Title: Improved method and system for asepticizing contact lenses and storing device.
Inventor: BARON NEVILLE A
IPC: A61L12/06
Filed: 1991-01-11
Abstract: Light-transmitting contact lenses of Polymethylacrylate, Gas Permeable of Hydrogel materials may be immersed in an aqueous liquid medium contained in a storing and processing device, all of which are substantially transparent to the ultraviolet radiation spectrum. The lenses, liquid medium and storing device are all irradiated with ultraviolet radiation in a preselected frequency range, while simultaneously being subjected to ultrasonic frequency vibrations to thereby cause asepticization of lenses, liquid medium and storing device. The ultraviolet irradiation and ultrasonic vibrations are insufficient to cause detrimental molecular modification to the lenses or storing device, but does cause the formation of oxidation free radicals in the liquid medium. The unique combination of ultraviolet irradiation and ultrasonic vibration in the presence of the liquid medium containing oxidation free radicals cause rapid destruction of all microorganisms associated with the lenses, liquid medium and storing device.

Abstract: La pression de vapeur réelle de compositions liquides, tout particulièrement de compositions à multi-constituants, est mesurée à l'aide d'un appareil (14) comportant un piston et un cylindre qui définissent une chambre de dilatation (84), dans laquelle un échantillon de liquide est piégé. La chambre (84) est dilatée en étapes multiples et des mesures de pression et de température multiples sont faites lors de chaque dilatation pendant une certaine durée. Lors de chaque dilatation, la pression résultante est déterminée à partir de mesures multiples en utilisant la méthode d'approximation des moindres carrés et les valeurs de pression résultantes sont extrapolées pour déterminer la pression de vapeur réelle en utilisant une approximation linéaire. L'appareil est conçu de manière à permettre des mesures continues de la pression de vapeur d'un courant de traitement en échantillonnant un courant de fuite de liquide qui est maintenu à une température constante. L'appareil est monté horizontalement afin de minimiser la profondeur du liquide et d'accroître la vitesse de formation de bulles durant la dilatation de la chambre.

Abstract: Superconducting composite elements having an oxide-ceramic superconductor material which is introduced into a metal sleeve are known as industrial conductors. The sleeve material preferred hitherto due to its good oxygen permeation was pure silver. However, this has the disadvantage of very poor mechanical properties, in particular low hardness and strength. A superconducting composite element (1) is therefore proposed in which the oxide-ceramic superconductor material (2) is surrounded by a sleeve material (3) of an oxide dispersion hardened or hardenable silver alloy. In particular, AgMgNi, AgMnNi and AgAl alloys are suitable for this purpose. In order to increase the specific resistance, the noble metal elements Ru, Rh, Pd, Os, Ir, Pt or Au can be included in the alloy. The composite element is produced by introducing the superconductor material into the oxide dispersion hardened or hardenable silver alloy sleeve, shaping the element to reduce the cross section, and subsequently heat-treating the element for recovery and adjustment of the oxygen concentration. <IMAGE>

Abstract: A closure (20) includes a grommet (50) having passageways (52-52) therethrough for allowing cables to extend into the closure. The grommet (50) comprises a unitary elastomeric body (60). Each passageway is defined by an interior sidewall from which a plurality of longitudinally spaced circumferential ridges (74-74) extend. For a substantial portion its circumference, each ridge has an axis of projection which forms an oblique angle with respect to a longitudinal axis of the associated passageway and is sufficiently elongated in longitudinal cross section so as to be capable of flexing with respect to the axis of projection during insertion of a portion of a cable and enlarging its opening diameter to accommodate and form a seal about the inserted cable portion. A slit (71) which is parallel to a longitudinal axis (73) of an associated passageway extends between end faces (62,64) and from the associated passageway to an outer surface portion of the grommet to facilitate insertion of a portion of a cable into the associated passageway. The grommet also includes a plurality of ribs (69,69) on an outer surface portion which provides a seal with a surface of an opening in which the grommet is disposed. Provisions are made to cause portions of each ridge and rib adjacent to each slit to be maintained with at least some overlap during installation and use of the closure in order to maintain the sealing effectiveness of the grommet.

Abstract: A technique for producing high reliability GaAs-AlGaAs heterojunction bipolar transistors by Molecular Beam Epitaxy with beryllium base doping. Beryllium incorporation and diffusion, during base-layer deposition, is controlled through a combination of reduced substrate temperature and increase As/Ga flux ratio during MBE growth resulting in extremely stable heterojunction bipolar transistor profiles. In addition, graded InGaAs surface layers with non-alloyed refractory metal contacts are shown to significantly improve ohmic reliability to alloyed AuGe contacts. High gain (DC beta) is achieved by the use of an increased substrate temperature during emitter deposition. The HBTs in accordance with the present invention are useful in a number of important microwave applications such as log amps, a/d converters, and sample and hold circuits where high reliability is desired.

Abstract: A rotary machine, such as a horizontally oriented scroll type refrigerant compressor is disclosed. The compressor includes a compressor housing, an inner block fixedly disposed within the compressor housing, a drive shaft extending substantially in the horizontal direction, and a driven mechanism, such as a compression mechanism operatively connected to one end of the drive shaft. The drive shaft is rotatably supported by the inner block and the compressor housing. A shielding element, such as an annular cylindrical member is fixedly held between the inner block and the compressor housing so as to prevent the drive shaft from passing through an oil sump of the housing. An internal lubrication oil pump is formed by the elements which are associated with the drive shaft, and is operated by virtue of the rotational motion of the drive shaft in order to supply the lubrication oil from the oil sump to the frictional surfaces of the internal component parts of the compressor. According to the construction and operational manner of the oil pump, the oil pump can be used for the various types of the horizontally oriented rotary machine. Furthermore, the drive shaft can rotate without receiving oil viscous drag.
