Abstract: A flat screen autostereoscopic display for bright wide angle stereoscopic images employs a flat screen on which are displayed a light pattern such as a plurality of regularly spaced, thin, vertical light emitting lines. The light lines are formed through use of electrically switchable materials such as liquid crystal or electrochromic materials. A transmissive electronic display, e.g., a liquid crystal display, is located in front of the light lines. The display and light lines are arranged in such a way that an observer sees the light emitting lines through one set of pixels with the left eye and the same lines through a different set of pixels through the right eye. Methods and apparatus for the simultaneous formation of a two-dimensional image and a three-dimensional image on such a transmissive electronic display, and for moving or dragging the display area of the three-dimensional image from one location to another on said display, are also disclosed.

Abstract: A photographic film construction at least one side of which is coated with an antistatic layer comprising a binder of gelatin grafted to a poly(ethylenic) polymer having acid functional groups on the polymer and a dispersion of vanadium oxide particles in the grafted gelatin binder.

Abstract: An improved side bearing for installation between a railcar body and the bolster of the railcar track, said side bearing having an open cylindrical housing with a mounting plate, a top cap for vertically reciprocating within said cylindrical housing and a one piece compression spring resisting the reciprocation of the top plate, the compression spring being formed, of a copolymer elastomer having a ratio of plastic strain to elastic strain that is greater than 1.5 to 1.

Abstract: A coating of a mixture of sodium metasilicate together with a silica sol and a silane coupling agent provides antistatic protection when overcoated with a gelatin containing photographic construction.

Abstract: A polymeric film substrate is first modified, then coated with a polyalkyl acrylate/gelatin layer to improve the wet adhesion of the layer to the substrate. The layer may itself contain a photographic emulsion or emulsion layers may be adhered to that layer.

Abstract: A coating of a mixture of sodium orthosilicate together with a silica sol and a silane coupling agent provides antistatic protection when overcoated with a gelatin containing photographic construction.

Abstract: This specification is directed to electrochromic optical shutter (10) in which an electrochromic material (12), an ion conductor (14), and a counter electrode (16), in that order, are sandwiched between visibly transparent electrodes (18). The shutter is improved by forming the ion conductor from a lithium-doped aluminum oxide applied to, as a base therefor, either the electrochromic material or the counter electrode. The material is applied by a pyrolytic spray process in which a solution containing lithium and aluminum as pyrolyzable organic salts dissolved in an organic medium are sprayed on the base. The base has been previously heated to a temperature sufficient to pyrolyze the sprayed materials and form a lithium-doped, aluminum oxide ion conductor layer. The counter electrode may be removed, in which case the ion conductor would be applied to either the electrochromic material or one of the visibly transparent electrodes.

Abstract: This specification is directed to electrochromic optical shutter (10) in which an electrochromic material (12), an ion conductor (14), and a counter electrode (16), in that order, are sandwiched between visibly transparent electrodes (18-18). The shutter is improved by forming the counter electrode from a nickel oxide applied to, as a base therefor, either the ion conductor or one of the transparent electrodes. The material is applied by a pyrolytic spray process in which a solution containing nickel as a pyrolyzable organic salt dissolved in an organic medium is sprayed on the base. The base has been previously heated to a temperature sufficient to pyrolyze the sprayed material and form a nickel oxide counter electrode layer.

Abstract: This disclosure teaches a new article of manufacture. The article includes a glass substrate and an adherent coating on the glass substrate of a gray color. The coating on the glass substrate has a composition selected from the group of glass coating compositions consisting essentially of oxides of cobalt, manganese, and copper, wherein the metal content of the metal oxide composition contains 45-60% by weight of cobalt, 26-39% by weight of manganese, and 12-20% by weight of copper. The actual weight percent of each metal is adjusted so that all metals are within their stated ranges when providing a total of 100% by weight metal. The coated glass substrate can be made into a product which has particular utility as a tinted architectural or a tinted automotive glass product.

Abstract: A tool for insertion and extraction of a packaged IC to and from a socket includes a pair of flexible, parallel arms joined at two ends by a "U" shaped portion. The free ends of the two when moved towards each other are adapted to grip the IC at opposite ends and allow a rocking motion to be applied to loosen the pins of the IC within the socket and then for a lifting force to be applied to remove the IC the socket, all with minimum distortion of the pins. A plunger having a base which is positioned and is free to move between the two parallel walls within the "U" is used to insert an IC into its socket. The IC is positioned between the two walls of the "U" with the pins of the IC pointing outwards and the surface opposite the pins in contact with the base of the plunger. The IC is retained within the "U" by a predetermined interference fit between the walls and the IC.

Abstract: A side bearing unit for attachment to a bolster of a truck of a railroad car has a base which may be fastened to a top wall of the bolster. A housing, carried by the base, includes spaced sidewalls joined by end walls to define a cavity for an elastomeric device. A cap, positioned within the housing, is integrally joined to the elastomeric device with a top surface of the cap located above the housing for engagement with a wear plate attached to a bottom of a body of the car. During travel of the railroad car, sets of side bearing units are particularly effective in regulating independent rolling of the car body as well as impeding truck hunting.

Abstract: A printer ribbon cartridge arranged to house an endless band of ribbon formed in a mobius loop which enables different halves of the width of the ribbon to be presented for printing during successive cycles of the ribbon past a printing position.The ends of the ribbon are joined in a lap splice so that the cut end of the half of the ribbon presented for printing trails as it passes the printing position.
