Abstract: Contact lenses are disinfected in a method including treating the contact lenses with an aqueous system of hydrogen peroxide in the presence of a hydrogen peroxide decomposition catalyst, and heating the system in order to accelerate decomposition of the hydrogen peroxide. In a preferred embodiment of the method, the initial concentration of hydrogen peroxide in the system is approximately 3-4% and the heating promotes decomposition of the hydrogen peroxide to a concentration of 50 parts per million or less within six hours following initial contact of catalyst with the system. The catalytic decomposition can be performed in a conventional lens sterilization vessel which is inserted within a heated receptacle to heat the reaction vessel and the contained sterilization system. The heated receptacle controls the temperature of the inserted vessel and sterilization system within a range of approximately 60.degree.-80.degree. C.

Abstract: Disclosed is a viewing system (30) for displaying and viewing stereoscopic images to a viewer's full field of view. The viewing system includes an image display assembly (32) including display surfaces (34) for displaying images primarily to the viewer's area of visual attention and display surfaces (36) for displaying images primarily to the viewer's area of peripheral vision. The display surfaces are mounted in relatively close proximity to the viewer's eyes. The viewing system further includes an optical component (33) having optical systems (40 and 42) for focusing images displayed on the display surfaces (34 and 36), respectively, to the viewer's eyes.

Abstract: The apparatus displays successive pictures of different-type game animals on a screen, preferably each for a predetermined interval of time. The bowman releases an arrow in an attempt to strike the heart or lung of each animal while its picture is being displayed. A scoring target overlies the screen and is imprinted with the heart and lung area identified for each animal, and in positional correlation with its displayed picture. Each arrow released is similarly identified so that after all arrows are released, the target can be inspected to establish a scoring accuracy of the bowman, by comparing each identified arrow with each heart and lung area aimed at.

Abstract: A bending section of an endoscope is constructed from non-round vertebrae. The vertebrae are D-shaped, having a planar portion and an arcuate portion. A first pair of protrusions extends from a first surface of the vertebra, defining a vertical bending axis. A second pair of protrusions extends from a second surface of the vertebra, defining a horizontal bending axis. Because the vertebra is D-shaped, the second pair of protrusions are farther from the longitudinal bending axis of the bending section than the first pair of protrusions. To provide uniform, symmetrical bending of the bending section, the first pair of protrusions are shorter than the second pair of protrusions. In addition, the first pair of protrusions extends at a different angle than the second pair and thus have a different shape, so that the first and second pair of protrusions are not symmetrically shaped with respect to each other.

Abstract: A lighting or indicating unit, such as a direction indicator, is fitted in a wing of a motor vehicle between the wing itself and a headlamp. A fastening means for fastening the unit includes a first zone of engagement between the unit and the adjacent wing, which defines a notional axis of rotation for the unit and determines, at least partly, the correct positioning of the latter with respect to the wing; a spring which applies a resilient force to the unit so as to apply a turning moment to the latter about the notional axis; and a second zone of engagement between the unit and the adjacent headlamp, this second zone being subjected to the turning moment and applying a reaction force which ensures that the unit bears on the wing in the first zone of engagement.

The proportions are preferably 60% to 70% glass fibre and 30% to 40% wollastonite.

Abstract: Methods and compositions for preventing or treating ophthalmic diseases or disorders wherein an ophthalmically effective amount of the C.sub.20 through C.sub.26 aminosteroids of formula XI and their pharmaceutical, acceptable salts, hydrates or solvates is administered in an inert vehicle to arrest oxidation processes damaging to the eye.

Abstract: A helmet-mounted night vision system that is compact, light in weight and ejection-safe. The system incorporates a night vision goggles apparatus for receiving incoming infrared and/or visible light from a viewed object and for converting the incoming light to an intensified visible light for presentation to an eye of a user, a visor mounted to a helmet to be worn by the user and adapted to be positioned in front of the night vision goggles apparatus, and connecting structure for connecting the visor to the night vision goggles apparatus for retaining the visor in position in front of the night vision goggles apparatus. By ensuring that the visor is safely retained in front of and substantially fully covers the goggles apparatus at all times, the system of the invention is rendered ejection-safe. The system also provides the user with numerous other structural and operational advantages.

Abstract: Improved linear sensor array and scanner apparatus and operating methods to reduce noise and streaking in a digitized image produced by the scanner. The scanner uses a charge coupled device linear sensor array having a pair of sensor output channels, each for processing one half of the array sensor elements which are interleaved with the other half of the sensor elements. To provide a reference, the CCD outputs are read a plurality of times with the system on but no article in scanning position, with the multiple readings for each sensor element being averaged to provide an average reference level therefor. These averages are stored in digital form, each to provide a calibration factor (multiplier) for the corresponding readings of the array during scanning of an article. During scanning, the output corresponding to each sensor element is multiplied by the corresponding calibration factor to normalize each output to a common reference.

Abstract: A multi-function headlamp, in particular for a motor vehicle, is arranged to improve the illumination of road signs and other external objects. It includes an occulting means for defining a cut-off line for a beam such as a dipped beam or fog penetrating beam, lamp means of the kind that emits both visible light and ultra violet radiation simultaneously, and a front closure glass of a material which is at least partially transparent to ultra violet radiation. The occulting means is also opaque to visible light radiation and at least partially transparent to ultra violet radiation, and the occulting means is mounted for displacement between an occulting position, in which it intercepts all visible radiation directed above the cut-off line, and a retracted position in which it has substantially no effect on the transmission of visible light radiation.

A control circuit may be used to automatically adjust the input signal levels as well as the combined output signal level.

Abstract: A motor vehicle headlamp glass washing apparatus comprises a jet nozzle mounted on a retractable jet carrier and supplied selectively from a source of washing liquid under pressure. The jet carrier comprises a variable volume chamber, which is defined by a fixed element and a movable element which slides on the fixed element and which carries the jet nozzle. A spring acts between the fixed and movable elements to bias the movable element into a retracted position. Supply of liquid under pressure to the variable volume chamber initially moves the movable element against the action of the spring into a deployed position, and then supplies the liquid to the jet nozzle.The fixed element is a tube open at a free end and connected to the liquid source at its other end, the movable element comprising a closed body having an internal space communicating with the jet nozzle.

Abstract: An apparatus for molding a soft ophthalmic lens, having a male and female portion, one having around the periphery of the optical surface a knife edge and one containing a rim bushing peripherally exterior to the knife edge. The two portions are mated so that the knife edge deformably penetrates the other portion. Excess material is expelled from the mold cavity and separated from the lens by a region of prepolymer discontinuity defined by the rim bushing contact area. The mold portion containing the rim bushing is produced by using a cylindrical insert and an annular sleeve machined to have the rim bushing on the surface of one end.
