  • Cosmonauts seal experiment A pair of cosmonauts in the Mir

    space station spent a fve-and-a-

    half-hour space walk to carry out

    an experiment on sealing minute

    cracks in the hul1 with specially

    designed glue.

    Cracks appeared when the

    station collided with a cargo craft in

    June 1997, and have caused

    constant air leakage from the cabin,

    forcing the crew to use more

    precieus energy to maintain normal

    pressure inside. Earher, other teams

    of cosmonauts tried to locate the

    puncture but failed.

    The latest attempt was said to be

    unsuccessful in stopping the

    pressure drop but mission control

    said experts believed the

    experience could be useful for

    further flights.

    Results of the experiment

    could come in handy during work

    at the International Space

    Station, the spokesman said,

    referring to a US$60 billion

    project in which Moscow is one of

    the main contractors after the

    USA. Russia says that Mir wil1 stay

    in orbit until at least August even

    though the cosmonauts also found

    that cables to a solar panel were

    blackened, indicating a short-


    Gasket problems delays launch Meanwhile, at Cape Canaveral,

    Florida, USA, the launch of the

    first US racket powered by a Russian designed and built

    engine was delayed because of a

    valve problem on the pad. Lockheed Martin Corp had

    hoped to have a fifth shot Sunday

    evening at launching its new Atlas

    111 racket with a European

    communication satellite on board.

    However, when it was routinely

    draining propellant from the racket

    after the failed launch attempt, a

    gasket in the liquid oxygen check

    valve wore out and delayed the

    work. Technicians were replacing

    the gasket as wel1 as the rockets


    Ironically, the scheduled launch

    attempt had been scuttled by a

    fishing tournament that drew more

    than 70 boats into the launch-

    danger area offshore, and a last-

    minute computer error. Earlier

    delays were caused by technical

    problems and bad weather.

    Gaska Tape foam solves auto problems Gaska Tape Inc has published a

    white paper describing the

    versatility of the companys new

    Polymerie Series Foam Tape for

    automotive applications:

    Polymerie Series Foam Tape:

    Solutions for a Wide Range

    of Problematic Automotive Applications details actual case

    studies of how this new material

    meets or exceeds some of the

    toughest automotive specification

    for both exterior and interior

    applications. The new white paper

    also details how Gaskas new

    generation of Polymerie Series

    Foam, patent pending, has cleared

    the way to meet or exceed the SAB

    J 1756 out-gassing specification.

    This makes polymerie the first

    material of its kind to exceed this

    hurdle without the aid of masking

    or coating.

    Seals workshop suspended The US Federal Aviation

    Administration has suspended

    certification for some of Qantas

    Airways maintenance and

    engineering operations on US

    aircraft. The suspension applied to Qantas bearing and seal

    workshop that works on engine

    bearings, rotating parts and

    seals. Technicalities included the

    kind of solvents used and the

    surface material of the workshop


    Qantas Airways says that the

    FAA issues do not affect the safe

    operation of its aircraft and that it

    was working on the FAAs


    Surgical sealant endorsed A US advisory panel has endorsed a surgical sealant made by Focal Inc for reducing or

    eliminating air leaks following

    lung surgery. A committee that advises the Food and Drug Administration unanimously

    recommended that the agency

    approve the sealant, known as FocalSeal-L, for marketing in the

    US. The sealant already is

    approved for use in Europe and Canada.

    The Lexington, MA, USA, based Focal hopes to sell the

    product in the USA market to

    prevent air leaks from occurring

    after surgery to remove lung

    tumours. If the FDA follows its

    panels advice FocalSeal-L would

    be the companys frst product

    approved in the US.

    There isnt anything more

    important than this, Focal

    president and chief executive

    officer Robert DePasqua said. Its

    nice to have approval for a product

    outside the United States, but our

    biggest markets are obviously


    The committee urged the FDA

    to require a warning on the

    products label that the clinical trial

    showed higher rates of wound

    infections and empyema, a

    collection of pus in a body cavity, in

    patients treated with the sealant

    than in the control group. They

    als0 recommended that

    the company conduct long-term

    studies to determine whether

    treatment with the sealant

    contributed to tumour growth.

    There needs to be further data

    accumulated before this question

    can be answered, said panel

    chairman Dr. Thomas Whalen,

    head of paediatric surgery at the

    Robert Wood Johnson Medical

    School in Camden, New Jersey.
