  • Hot gas, regenerative, supported H.sub.2 S sorbents
    Patent number: 5252528
    Abstract: Efficient, regenerable sorbents for removal of H.sub.2 S from moderately high temperature (usually 200.degree. C.-550.degree.C.) gas streams comprise a porous, high surface area aluminosilicate support, suitably a zeolite, and most preferably a sodium deficient zeolite containing 1 to 20 weight percent of binary metal oxides. The binary oxides are a mixture of a Group VB or VIB metal oxide with a Group IB, IIB or VIII metal oxide such as V-Zn-O, V-Cu-O, Cu-Mo-O, Zn-Mo-O or Fe-Mo-O contained in the support. The sorbent effectively removes H.sub.2 S from the host gas stream in high efficiency and can be repetitively regenerated at least 10 times without loss of activity.

  • Dental applicator
    Patent number: 5244388
    Abstract: Dental impression material is applied to the surfaces of teeth under pressure and in a direction of flow perpendicular to the underlying tooth surface. The impression material is pushed into the sulci, interstices of teeth and crevices in adjacent tissues which presses air out and prevents formation of voids. The applicator can be an accessory which is frictionally and sealingly received over the tip of a syringe. The distal end of the applicator may contain a vertical flap spaced from the outlet orifice and adjacent side walls, forming a chamber. As the impression material is extruded, it collects in the chamber under pressure. The end wall may be hinged to wipe the material onto surfaces and may be cut into mini-flaps to conform to cusps and adjacent depressions on occlusal surfaces of teeth.

  • Self closing hinged syringe guard
    Patent number: 5242417
    Abstract: A syringe is molded with an integral needle cover or guard that pivots about a main living hinge on the side of the syringe near the base of the needle. A tension spring formed from an L shaped integrally molded part of the syringe and guard extends from a location closer to the syringe than the main living hinge to the center part of the pivoting guard. The user, while holding the syringe with one hand, can extend a finger to initiate rotation of the guard toward the needle. This extends the tension spring at first, but beyond a certain angle, the tension spring contracts again, pulling the guard the rest of the way into a position surrounding the needle.

  • Cryogenic thermoelectric cooler
    Patent number: 5241828
    Abstract: A Seebeck effect thermoelectric cooler, operative at cryogenic temperatures, in which two materials having different Seebeck coefficients are in electrical contact so that current flow thereacross cools the junction. One or both of the materials comprise a metal-insulator transition material characterized by doping, alloying, or other means to be just slightly metallic so that electrical resistance becomes lower at lower temperatures, but the Seebeck coefficient does not decline at lower temperatures, as would be the case if the material were allowed to become fully metal-like.

  • Rapid miosis with control of intraocular pressure using a mixture of a cetylcholine and carbachol derivatives
    Patent number: 5229127
    Abstract: Quick miosis with 24 hour control of intraocular pressure of patients undergoing extracapsular cataract extraction surgery is achieved by applying to the eyes of the patient during surgery acetylcholine as a first miotic agent and carbachol as a second miotic agent. Acetylcholine provides quick miosis while carbachol enhances the miotic effect while providing post-surgery control of intraocular pressure. The two miotic agents can be dissolved in a common saline carrier. The two agents can be combined in a unit dosage package by disposing acetylcholine in powder form in a first compartment and a solution of carbachol in a second compartment. The combined miotic agent of the invention is especially useful when substances which raise IOP such as viscoelastic agents are used during ocular surgery and/or with sensitive patients who enter the surgery with elevated pressure such as those suffering from glaucoma.

  • Surgical drill collet mechanism and bur
    Patent number: 5222956
    Abstract: A surgical drill uses burs with circular grooves about the circumference that are polygon shaped in cross section but curved along the length of the bur so as to accept locking balls therein. The burs slide within a tubular drive shaft that has transverse holes therein to guide the locking balls. A cylindrical cam surrounds the drive shaft and the locking balls to urge the balls radially inward into the bur groove. The cam is spring loaded axially. A spring loaded central pin within the drive shaft slides between the balls and urges the balls radially outward when no bur is inserted. A thumb button is used to disengage the ball surrounding cam.

  • Superconducting junctions and method of making same
    Patent number: 5219826
    Abstract: A superconducting Josephson junction is created in high T.sub.c superconducting film, with a bridge connecting two superconducting banks, by subjecting the bridge to a tunneling electron current from a sharp electrode close to the bridge. The tunneling current alters the structure over atomic dimensions to create a weak link of length comparable to high T.sub.c coherence lengths so as to permit phase coherent Cooper pair current flow across the weak link.

  • Superconductor deposition system
    Patent number: 5207884
    Abstract: To deposit a plurality of substances on a substrate while the substrate remains in a low pressure oxygen environment, several target carriers are mounted around the edge of a disc and the disc is rotated to position the targets at the focal point of a fixed laser. The target carriers are themselves rotatable in bearings on the disc and are turned by a sun gear that is carried about the same shaft that turns the disc so that the heat of the laser beam is not concentrated at one spot on the surface of the target. All the apparatus is contained in a oxygen chamber. The substrate is heated and the targets are cooled continuously.

  • Stoop labor assist device
    Patent number: 5176622
    Abstract: A hip mounted, springable frame that compresses between the chest and thighs of a worker when he stoops over so as to help the worker to stand erect again and ease back strain. The center of the frame comprises a pair of arc-shape springs that wrap around cylindrical spools of elastomer. The spools are attached to a belt surrounding the worker's waist at hip level. The frame is easily removed and reattached by snapping the springs over the spools. Wear is reduced since there are no moving parts, and the spring forces are adjustable with the use of variable compliance and or springs having different spring constant such as priorities by different spring geometry.

  • Hanging heating element for high temperature furnace
    Patent number: 5157242
    Abstract: Six curved hanging electrical heater panels made of tungsten or molybdenum are arranged to form a hollow cylinder, and are supported at their upper ends by electrical connectors. The hanging panels are electrically interconnected at adjacent lower corners by removable links. Six phase electrical current is applied to the hanging panels through the respective upper connectors, with phases of opposite polarities being applied to diametrically opposed panels. The net current flow through the removable links is zero, enabling the links to be designed to fail electrically and/or mechanically before the panels, thereby protecting the panels from electrical burnout and mechanical damage. Each removable link includes a unique arrangement of a link member, two pins, and a wedge which tightly interlocks the pins, link member and panel corners together.

  • Grain boundary junctions in high temperature superconductor films
    Patent number: 5157466
    Abstract: Grain boundary, weak-link junctions are formed at a predermined location of a uniform, planar substrate by depositing superconducting film on two sections of the substrate. The film is grown as a bicrystal having two distinct areas of superconducting film whose crystal lattices are rotated with respect to each other, either in-plane or out-of-plane, by more than 5.degree. and less than 90.degree.. The grain boundary acts as a weak link junction. The film can be induced to grow as a bicrystal by depositing intermediate strata such as seed layers or buffer layers or by modifying the growth conditions during deposition.
