Sealing Stainless Steel

by

Amy Nutt..

Many products are made of stainless steel. These products can be countertops, buildings, appliances, and so much more. It is hard to list them all because everyone encounters a stainless steel item or structure every single day, which defines steel as being a very important material used in the construction of many everyday goods. Depending on the type of product depends on whether or not stainless steel needs to be sealed. Items such as countertops do not have to be sealed because they are usually one large slab placed upon a base.

However, there are certain items or even components of items that must be sealed. Take the cook stove, for instance. The cook stove may actually be made up of two different types of materials such as aluminum and stainless steel. These two metals have to be fused together in some way. Even certain components such as screws need to be altered in order to work properly with both types of metals and keep the appliance intact. There are various methods in which stainless steel is sealed and there are times when it needs to be completely sealed, partially sealed, or not sealed at all.

Aluminum and stainless steel tend to be two metals that are commonly used together. Certain components may require sealing and these components can be sealed with a corrosion resistant primer.

Instances in which this sealing may occur between steel and aluminum are:

Heat sealing

Heat sealing is another method used to seal stainless steel. This method uses heat to seal two pieces of a material together at the place in which the pieces connect. The temperature in which these materials are heat sealed reach the temperature at which fusion occurs, which also involves a certain degree of pressure.

Thermal sealing

In instances where temperature may remain constant because of a rotating wheel, the sealing is considered to be thermal sealing. The remainder of the process is the same of heat sealing because temperatures reach the point of fusion in which the two pieces of steel fuse to each other, making a very strong bond between the two.

Impulse sealing

Impulse sealing involves the heat being applied to the steel by resistance elements, which are applied to the project when the metal is relatively cool and then heated at a rapid rate. It is through this method that simultaneous cutting and sealing can be performed.

Dielectric sealing

Dielectric sealing uses radio frequency waves to induce heat within the steel. However, if ultrasonic vibrations are used in sealing, this is called ultrasonic sealing.

It is obvious to see that there are many methods of sealing. Some may even prefer to call it welding. Everyone has most likely seen someone with a welding torch and a face mask fusing together two pieces of metal. In this case, two pieces of stainless steel can be sealed together to form many types of objects and structures. Nevertheless, the next time you see two pieces of stainless steel

forming a 90 degree angle, you will know how it was probably done.

A permanent memorial for the victims of the July 7, 2005 London bombings has been unveiled in Hyde Park, London, England. Today is the fourth anniversary of the bombings, when 52 people were killed by suicide bombers on board three Underground trains and a bus.

52 stainless steel columns standing 3.5m (11.5ft) tall were inaugurated in the presence of Prince Charles, the Duchess of Cornwall Camilla Bowles, Prime Minister Gordon Brown, London Mayor Boris Johnson and Minister for London, Tessa Jowell.

Each column represented “a unique person and a unique grief” according to the Minister for London.

Jowell continued, “Each one casts a shadow just as they do – each one standing tall and proud just as they did, and each one will in an individual way absorb and reflect light just as they did.”

A 1.4 tonne stainless steel plaque with the names of the people killed was also unveiled.

Prince Charles laid a wreath on behalf of the nation. The Duchess of Cornwall left a floral tribute for the families of the victims.

The families themselves laid roses and then met the prince and the duchess.

In our last summer vacations while returning from Goa we took a halt at Malvan. The halt actually was not a pre planned visit. It was possible for us to take halt as we were travelling in our own vehicles. The visit being not previously planned we were supposed to make our own arrangements upon arrival. We made enquiry with the local people but were not satisfied from the feedback. So we adopted the best alternative of contacting the local travel agency office. The info we received was there were many budget and luxury hotels in Malvan city. Some of the hotels were also near Malvan beach. We dropped the idea of booking the hotel through the agency. Taking advantage of our Laptop with internet we searched hotels over various available sites to book hotels via. Online booking facilities. We were surprised to see a list of budget and luxury hotels and resorts at Malvan, because we imagined Malvan to be only a small town. When tried for booking a budget hotel in Malvan we came across Hotel Sagar Kinara as it was the only hotel which displayed some good images about their hotels. So without any further delay we booked two rooms in Hotel Sagar Kinara Malvan near Sindhudurga fort. After we checked in we decided to have some rest before venturing out. In the evening went to the Malvan city center purchased some required stuff and went straight away on a round trip of Tarkarli beach, Chiwala beach and Tondavali beach. The Tarkarli beach which is around six km from Malvan had crystal clear water and it was one of the hot spot for snorkeling and scuba diving. The convergence of Karli River with the Arabian Sea is the most spectacular scene. Next morning we went to the Sindhudurg fort for trekking.

We enjoyed our stay at Hotel Sagar Kinara, Malvan and enjoyed its popular Malvani sea food. The hotel was very comfortable because of its proximity to the city as well as the beaches of Malvan. Upon request the hotel staff also arranged Dolphin Safari for us. The unexpected halt at Malvan and stay at Hotel Sagar Kinara was a unique experience, which was pleasure to remember. Exactly on the third day we were back on our journey back to Mumbai, but Malvan was still appeasing before our eyes.

You can also enjoy your visit to Malvan staying at any one of the budget or luxury hotels near Malvan beach. These hotels can be booked online too. If you ask us we would be suggest you to book Hotel Sagar Kinara, as we had one of the best experiences there in Malvan.

United States congresswoman Stephanie Tubbs Jones, representing Cleveland, Ohio died on August 20, 2008 following a brain aneurysm.

Jones was observed by police driving erratically on the evening of August 19, 2008. When police approached her car, they found her unresponsive. She was rushed to Huron Hospital in East Cleveland, where she remained overnight. She never regained consciousness. Jones died the following day, at 6:12pm EDT (UTC-4).

Stephanie Tubbs Jones leaves behind a son, Mervyn Leroy Jones II. Her husband of 27 years died in 2003.

Senator Barack Obama issued a statement: “Michelle and I are saddened to hear today’s news about Rep. Stephanie Tubbs Jones. She is a passionate and tireless advocate for the people of Cleveland and a devoted public servant for all Americans. We send our heartfelt prayers to Stephanie and her family at this very difficult time.”

The mayor of Cleveland released the following statement prior to Jones’ passing: “My thoughts and prayers are with Stephanie and her family. I have known the Congresswoman for my entire political career and for several years prior to taking public office. She has supported me professionally and has been a loyal friend. As a public servant, she has stood firm with, and for, so many of us and I am asking everyone to take a moment to pray that she makes a full recovery.”

From 1991 to 1999, she was the prosecutor in Cuyahoga County, Ohio. She was both the first female and the first African American to hold this office.

Jones had served in the United States House of Representatives since 1999 and was currently the co-chair of the Democratic National Committee. She was the first African American woman to be elected to Congress from Ohio.

Paris hotel fire kills 22

A Paris fire in a hotel killed 22 people, 10 of whom were children, while injuring 53 — 11 seriously. The hotel was an overcrowded, budget accommodation type of housing. Most of the inhabitants were African, many housed by social services, according to an Associated Press report.

The 32 room, six-story Paris Opera hotel, was made to house 61 guests, but 90 were staying at the time of the fire, with 84 of them placed by city or state social services.

The fire is thought to have started in the breakfast room at 2:20 am Friday, local time.

Along with the Africans, who were mostly refugees, others wounded included French, Senegalese, Portuguese, Americans, Ukrainians, and Tunisians, according to a report from Turkish Zaman.com. The hotel is situated near to La Galerie Lafayette, Printemps shopping center, and Paris Opera.

It took nearly 250 fire-fighters to control the fire, and the number of casualties was high because of the single exit.

“It’s hard in that kind of situation to tell people to calm down. They jumped. People on the first floor threw their children out the windows,” Alfred Millot, head of the fire service at the nearby upmarket Galeries Lafayette department store, told Agence France-Presse.

“With our own equipment, we started fighting the fire from the ground floor. I came running and people were already jumping through the windows,” said Millot.

His store warehouse was used as a temporary morgue. Families were counselled and assisted in re-uniting by the Red Cross.

Cypriot cargo ship “Server” went down in Norwegian territory of the North Sea near the Norwegian city Bergen around 6pm local time on January 12. The ship broke into two parts and the accident is described as a catastrophe for the environment in the area due to a significant fuel oil leak. The oil reached land a short time after the breakdown.

The entire 25-man crew was brought to land around 9pm by a Sea King-helicopter. At noon next day it was reported that 290 tons of heavy fuel oil had leaked out onto the sea. The spilt oil has covered ground along the coast and is reported to be still spreading. A nature reservation area for birds is in imminent danger of pollution.

Pain Pump Litigation ? News, Updates, Settlements Information

Using a pain management pump following minor joint surgery has turned into a nightmare for many people across the country. After seemingly routine procedures, many people start to develop cartilage damage as a result of these pain pumps. This condition is called PAGCL or Postarthroscopic Glenohumeral Chondrolysis. Evidence is mounting that the manufacturers of these pumps aggressively promoted the use for shoulder as well as knee and ankle surgeries, and litigation is pending. There has been a lot of research done regarding chrondrolysis.

One interesting study was titled: Bilateral Shoulder Chondrolysis Following Arthroscopy

A Report of Two Cases

Here is an exerpt:

?Shoulder arthroscopy has become a common means of treating shoulder instability. Recent reports have documented the rare but devastating complication of chondrolysis following arthroscopic shoulder procedures. Although the cause of chondrolysis following these procedures remains unclear, an association with a number of variables has been suggested.

We present the cases of two individuals, each of whom presented to our institution for the evaluation and treatment of severe shoulder pain after having undergone bilateral arthroscopic shoulder procedures at separate operative times at another institution. Each patient subsequently developed severe chondrolysis of both shoulders. The demographic information, surgical records, and clinical course of the patients were reviewed in an attempt to identify factors associated with this problem. Our patients and the original treating physician were informed that data concerning the cases would be submitted for publication, and they consented.?

Subacromial pain pump use with arthroscopic shoulder surgery: A short-term prospective study of complications in 583 patients

Journal of Shoulder and Elbow Surgery, Volume 17, Issue 6, Pages 860-862

Here is an excerpt:

?Abstract

Pain pumps containing local anesthetics, with or without opioids, can be used for perioperative analgesia after arthroscopic shoulder surgery to reduce pain. Although several smaller studies have demonstrated the analgesic properties, no large series to date has reported the short-term complication rate of subacromial pain pumps. We prospectively studied (2005 to 2007) 583 patients who underwent arthroscopic shoulder surgery at a single outpatient surgery center and had intraoperative placement of a pain pump catheter into the subacromial space. Patients had at least 1 month of follow-up. No patient received perioperative brachial plexus regional anesthesia. There were no cases of infection, internal catheter breakage, pump failure, or hospital admission for pain control. The only complication was external catheter breakage that occurred when a patient attempted to remove the pump without removing the tape fastening the catheter at the skin. Subacromial pain pumps used for arthroscopic shoulder procedures are safe in the short-term.?

A number of pain pump lawsuits have been filed in state and federal courts across the country. If you have been harmed by one of these pumps, you should contact an attorney as soon as possible to discuss your legal rights. This article should not be construed as medical or legal advice.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.
