Patent number: 4800188Abstract: A method for supporting metalloporphyrins on polybenzimidazole articles is disclosed herein. Microporous polybenzimidazole articles are treated with a strong base to produce an anionized polybenzimidazole article. A metalloporphyrin salt is dissolved in a solvent and is mixed with the anionized polybenzimidazole article to produce a microporous polybenzimidazole metalloporphyrin complex. This compound can be used in the selective oxidation of alkanes, olefins and aromatic compounds and is quite useful in the separation of oxygen from a gas stream. An alternative method of forming this complex by mixing directly the polybenzimidazole particulate with a weak metalloporphyrin salt without the use of a strong base results in lower percentages of substitution then does the principal method.Type: GrantFiled: March 20, 1987Date of Patent: January 24, 1989Assignee: Hoechst Celanese Corp.Inventor: James P.

Patent number: 4728780Abstract: This invention concerns a heating pipe for panel heaters disclosed on walls, ceilings or floors to heat a room. The pipe is essentially constructed of a pipe itself, an electric heating wire running through it and aluminum granules stuffed between the two. Because of the simple structure, the production, the installment and the maintenance costs are cheap; as a matter of course, there is no additional need of a circulation pump for heating media and safety devices to watch the leak of heating media or the break of the pipe. Moreover, because spherical aluminum granules are closely packed, the heat conductivity is very good, which minimizes the heat loss and reduces the time to heat up a room. Also, the heat capacity is so small that frequency room temperature control by means of an automatic on-and-off mechanism has becomes possible.Type: GrantFiled: July 14, 1986Date of Patent: March 1, 1988Inventor: Eiji Uchino

Patent number: 4600642Abstract: Small lengths of conductors, cut to the appropriate size are used as radar "chaff" or passive reflectors to give spurious returns on an enemy radar and thereby act as an electronic countermeasure. Currently used chaff includes chopped aluminum foil, aluminum coated glass fibres and silver coated nylon monofilaments. Current radars operate in the 10.sup.10 Hz region and current chaff dipoles are of centimetric size, but future radar systems are likely to operate at higher frequencies requiring shorter dipoles lengths to achieve an increased packing density the dipoles also need to be thinner. Carbon fibres have advantages over existing chaff materials as they are fine, light and much stiffer than existing chaff materials. The electrical resistance is about 1000.times.higher than that of aluminum however and this invention therefore proposes the use of carbon fibres coated with a much more conductive coating. Typical coating materials can be copper, silver aluminium applied by a number of different methods.Type: GrantFiled: November 13, 1984Date of Patent: July 15, 1986Assignee: Plessey Overseas LimitedInventors: Kevin J.

Patent number: 4581291Abstract: A coaxial cable is provided having a ribbon inner conductor surrounded by a dielectric and a circumferential conductor. The coaxial cable may be microminiature comprising a very thin ribbon strip conductor from between 5 to 15 .mu.m thick and from 150 to 200 .mu.m wide, having a surrounding foamed dielectric or parylene applied thereon by a vapor plasma process and an outer conductor of an adhering high conductivity metal vacuum deposited on the dielectric. Alternately the foam dielectric embodiment may have a contiguous parylene coating applied adjacent the inner conductor or the outer conductor or both. Also, the cable may be fabricated by forming a thin ribbon of strip conductive material into an inner conductor, applying thereabout a dielectric by spraying on a solution of polystyrene and polyethylene and then vacuum depositing and adhering high conductivity metal about the dielectric.Type: GrantFiled: December 29, 1983Date of Patent: April 8, 1986Inventor: Wayne L. Bongianni

Patent number: 4556508Abstract: An electrically conducting material including a cyanic group-containing material substrate and adsorbed sulfides of copper and an auxiliary metal selected from silver, gold and elements of the platinum group. The cyanic group-containing substrate may be in the form of powder or a shaped body such as a fiber, film, plate, rod or like suitable substrate include a synthetic polymers such as polyacrylonitrile and polyamides having cyanic groups; naturally occurring polymeric substances such as cotton having introduced thereinto cyanic groups; and low molecular weight compounds such as phthalonitrile. The electrically conducting material may be prepared by treating the cyanic group-containing substrate with (a) a source of monovalent copper ions, (b) a source of ions containing the auxiliary metal and (c) a sulfur-containing compound to form sulfides of copper and the auxiliary metal adsorbed by the cyanic group-containing material.Type: GrantFiled: January 26, 1983Date of Patent: December 3, 1985Assignee: Nihon Sanmo Dyeing Co., Ltd.Inventors: Shinji Tomibe, Norio Murasaki
