Title: Process for thermal conversion of hydrogen sulfide to elemental sulfur
Inventor: HEISEL MICHAEL
IPC: B01D53/50
Filed: 1992-06-30
Abstract: Abstract of the Disclosure For the thermal conversion of hydrogen sulfide con-tained in a gaseous stream, the gaseous stream is intro-duced into a non-catalytic reactor together with sulfur dioxide obtained from a waste gas purification facility arranged downstream of the reactor.  (If necessary, the sulfur yield can be regulated by feeding additional fuel gas and/or reducing gas and/or process air into the reac-tor.)  The thus-produced vapor-phase sulfur is condensed out by cooling and is obtained as a product; the resul-tant gaseous stream extensively freed of sulfur compounds is discharged and fed into the aforesaid downstream waste gas purification facility.

Title: Process for manufacturing tagatose
Inventor: BEADLE JAMES R
IPC: C13K13/00
Filed: 1991-01-07
Abstract: A process is disclosed for the synthesis of D-tagatose by isomerizing a mixture containing D-galactose with a metal hy-droxide in the presence of a catalyst at a relatively low temperature to form an intermediate metal hydroxide-D-tagatose complex, and then neutralizing the intermediate with acid to yield D-tagatose. The method is also suitable for the synthesis of L-tagatose from L-galactose, and for the recovery of pure tagatose from crude tagatose syrups. Whey, deproteinized whey, or lactose may be used as the raw material for the D-galactose. The lactose in such cases is hydrolyzed to D-galactose and D-glucose before the is-omerization step.
Patent CA-2077742-A1 (CA)
Title: Syringe with protective housing
Inventor: HOLLISTER WILLIAM H
IPC: A61M5/31
Filed: 1992-09-08
Abstract: To provide a high degree of protection against the possibility of someone being accidentally punctured by a contaminated needle, the syringe of the present invention has directly connected thereto a protective housing, which can be pivoted to a position in alignment with the contaminated needle to envelop the same. As the housing is pivoted into the alignment position, locking mechanisms integral of the housing would fixedly retain the needle within the housing. The syringe of the present invention may be modified to include a housing containing an integral collapsible section and a sealer adapted to the distal portion of the housing such that, upon collapse of the collapsible section of the housing, the tip of the contaminated needle would penetrate into and be sealingly secured by the sealer. Another modification of the syringe of the present invention involves utilizing a collapsible hinge to connect the protective housing to the main body portion of the syringe. Upon collapse of the collapsible hinge, the longitudinal distance separating the housing from the main body of the syringe is reduced, thereby causing the tip of the contaminated needle to pierce and penetrate into the sealer and be sealingly retained thereby.

Title: Electrotiltable material (tilter)
Inventor: CULP GORDON W
IPC: H01L41/09
Filed: 1992-11-04
Abstract: Abstract Tilters 2, are made of an electroiltable material comprising an electroshearable   material   having   a   unidirectional   gradient   of responsivity, such as piezoelectric ceramic. Responsive to an activating electrical signal, tilters 2, tilt surfaces 26, with large side strain and negligible side stress.  Forcible tilt provides forceful positioning of  objects  such  as  rollers,  optical  elements,  and  fluids.  Tilting combined with a normal  force of traction 16, forcefully moves a roller 12. Rollers pass tilting power to objects 14, in tractive contact such as a motor shaft 14. Alternating activation sense and tilting gradient 10 giving zero tilt at support surfaces 7, provide rigidity with negligible stress. Other embodiments use tilt to position optical elements, vary the flow resistance of  fluid  in a duct,  and bunch charged particles.  The actuator's tiltable surface 26 has an  optical  or acoustic  element 52 attached for changing the angle at which radiation interacts with the element. A variant having tilt position sensors constitutes an accurate angular accelerometer.

Title: Color Head-Up Display System
Inventor: SUVADA THOMAS C
IPC: G02F1/1347
Filed: 1992-11-19
Abstract: A field sequential color head-up display system includes image generating means including a source of light of at least two different wavelengths. A color selective polarizing filter having first and second absorption axes, enables the passage of linearly polarized light of first and second colors.  Optical retardation imposed by variable optical retarding means determines the color of the light transmitted by circular polarizing means.  Image collimating means apply a generated image of selected colors to an image combiner placed in the line of sight between an observer and a scene, thereby superimposing a generated image over the scene visible to the observer.  Holographic elements tuned to the selected wavelengths improve reflection of those wavelengths to the observer.

Title: Method of forming coatings by plasma spraying magnetic- cermet dielectric composite particles
Inventor: BULLOCK RONALD E
IPC: C23C4/02
Filed: 1993-07-16
Abstract: A method of forming high temperature resistant coatings from a quantity of composite particles, each comprising very small magnetic particles in a ceramic matrix by plasma spraying the composite particles onto a surface. Typically, the surface to be coated is pre-treated by a combination of solvent cleaning and abrasion, such as by- grit blasting. In some cases the surface is coated with a thin electrically conductive transition layer having a coefficient of thermal expansion intermediate those of the surface and the composite coating. A quantity of finely divided composite particles are then prepared, each of the particles comprising a ceramic matrix containing plural spaced very small magnetic metal particles. In some cases, a small quantity of smaller pure matrix particles or lower melting particles are mixed with the composite particles to improve bonding. The composite particles are plasma sprayed onto the surface to be coated at temperatures such that only the surfaces of the composite particles are melted, thereby permitting higher magnetic material loadings without forming an excessively electrically conductive coating. The resulting coating is durable, has high temperature resistance and absorbs incident microwave energy.
