Title: Pharmaceutical preparation and method for inhibiting replication of htlv-iii (aids) virus
Inventor: USHER THOMAS C
IPC: C08L/
Filed: 1988-08-02
Granted: 1992-08-25
Abstract: ABSTRACT          Dextran sulphate and salts thereof are used to inhibit replication of HTLV-III (AIDS) virus both in vivo and in vitro.  The same compounds are used in solution to inhibit the destructive action of HTLV virus upon human lymphocyte T helper cells.  The dextran sulphate or salts thereof may have a molecular weight in the range of 3,000-500,000 and a sulphur content of 12-25% with a preferred molecular weight range of about 7,000-12,000.  In view of the fact that the most effective dosages are such that the anticoagulant activity of dextran sulphate offers a significant potential to cause bleeding or hemorrhaging after extended use applicant has discovered that the hydrogenation of the dextran prior to sulfation produce a dextran sulphate derivative having   a greatly lowered anticoagulant activity  without affecting efficacy and thus permits the administration of higher dose levels of the compound.

Title: Process of dezincifying a material flow when operating a pig-iron production plant
Inventor: KEPPLINGER WERNER
IPC: C21B13/14
Filed: 1988-11-09
Granted: 1995-04-04
Abstract: Disclosed is a process of dezincifying the flow of material during the operation of a plant for the production of pig iron including a direct reduction shaft furnace and a meltdown gasifier.  A crude reducing gas drawn off the meltdown gasifier is dedusted in two steps.  In the first step, zinc-poor coal dust is separated in a cyclone operated at a higher temperature, which is recycled into the meltdown gasifier.  In the second step, upon cooling of the gas leaving the first cyclone, solid particles enriched with zinc are separated at a lower temperature. The dezincified reducing gas is fed to the direct reduction shaft furnace and the zinc-rich substances separated off the second cyclone are processed to a zinc concentrate.

Title: Corrosion resistant fuel cell substrates
Inventor: BOSE SUDHANGSHU
IPC: H01M4/88
Filed: 1989-02-10
Granted: 1993-08-03
Abstract: Abstract of the Disclosure A porous substrate of a fuel cell electrode assembly is formed by producing a fibrous carbon precursor web by means of a conventional wet paper-making process.  The precursor web is then dried and saturated with a wet resinous binder which will carbonize when heated.  Substantially the entirety of all of the carbon fibers in the web are thus coated with the binder, and substantially all of the inter-fiber junctures in the web will also be coated with the binder.  The saturated web is then dried, and heat treated to convert the binder to a glassy carbon which exhibits superior resistance to corrosion.

Title: Magnetic stem and vertically fixed pocket device for a stationary riveting machine
Inventor: EARL GORDON C
IPC: B21J5/10
Filed: 1989-02-17
Granted: 1993-04-20
Abstract: ABSTRACT   A magnetic riveting stem and a novel vertically fixed pocket device is provided for a stationary riveting machine which permits stationary riveting machines to be used for riveting applications which were impossible or impractical with prior art stem and pocket devices. The vertically fixed pocket receives ferrous rivets from a rivet feed mechanism and aligns them in a head-up orientation to be picked up by the stem for setting through the registered holes in the work.  A stationary riveting machine equipped in accordance with the invention is capable of setting a ferrous rivet in practically any location on a work piece where the head of the rivet can pass.  This offers an advantage over traditionally equipped stationary riveting machines which require vertically displaceable pockets for guiding a rivet to the pilot pin of a rivet anvil.

Title: Dispersion-compensating diffraction grating
Inventor: JOHNSON KENNETH C
IPC: G02B5/18
Filed: 1989-09-11
Granted: 1993-08-24
Abstract: ABSTRACT      A transmission grating is used to reduce chromatic aberration in an optical system, wherein the system's chromatic dispersion is offset and substantially canceled by the grating's diffraction-induced dispersion. The grating comprises a Fresnel-type pattern of microscopic facets molded directly into one of the system's refractive optical surfaces. The facets would typically have a profile height of around 4.10-5 inch and a profile width of at least 10-3 inch. In its primary intended application, the invention would function to improve the optical performance of a Fresnel lens used to concentrate direct sunlight into a piped daylight illumination system. For this application, about a ten-fold reduction in chromatic dispersion would be attained with only about a 2% loss in optical efficiency.
