Granted: 1992-08-04
Abstract: ABSTRACT OF THE DISCLOSURE           A microprocessor-controlled microfiche viewer which is adaptable for displaying microfiche having any format. The viewer calls up selected microfiche images in either a sequential mode or a random mode.  In the sequential mode a carrier table follows a default sequence, and is cued by a keyboard control, by a dual-tone audio cueing signal that is received over a telephone line or from a tape player, or by a digital signal from an RS-232 port.  In the random mode, particular images are selected by moving the carrier table in desired directions with directional keys, or by providing the coordinates of an image to the microprocessor.  Image coordinates are entered manually at the keyboard, by dual-tone audio signals from a telephone line or a tape player, or by data from the RS-232 port.  Means are provided for generating audio tones for recording cue signals on one track of an audio tape while playing back an audio accompaniment pre-recorded on the other channel, in order to synchronize the selection of images with an audio commentary.  Also provided are means for holding the microfiche flat in the focal plane of the projection lenses, and a system of marking either the fiche to be viewed or a blank formatting fiche to adapt the viewer to the proper format.

Granted: 1991-07-16
Abstract: VEHICLE RESTRAINT Abstract of the Disclosure A vehicle restraint for preventing a vehicle such as a truck from accidentally pulling away from a loading dock during a loading operation.  The vehicle restraint comprises a mounting plate mounted on the front vertical face of the loading dock and a slide is mounted for movement on the mounting plate and is bias-ed to an upper position.  The slide is provided with an angular front surface that is inclined downwardly and outwardly.  When a truck backs toward the loading dock, an abutment, such as an ICC bar at the rear end of the truck, will engage the inclined surface, wedging the slide downwardly against the force of the biasing means and the ICC bar will then be received within a recess or notch located in the upper edge of the slide.  To release engagement of the ICC bar from the notch, a release bar is moved upwardly into engagement with the ICC bar, thereby driving the slide downwardly against the force of the biasing means to release the ICC bar from the notch and enabling the truck to pull away from the dock.

Granted: 1990-11-27
Abstract: CROSSLINKED POLYMERS WITH LOWERED RESISTIVITY AND MATERIALS AND    METHODS FOR THEIR PREPARATION            Abstract New crosslinked polymers are prepared from a combination of starting materials comprising a polymer, a crosslinking agent for the polymer, and a conductivity agent containing a quaternary ammonium moiety.  The conductivity agent contains at least one functional group which, during an otherwise typical process of crosslinking the polymer through the crosslinking agent, reacts to bond the conductivity agent covalently and pendently to the crosslinking agent or the polymer.  The resultant crosslinked polymer has lower electrical resistivity due to inclusion of the conductivity agent.

Title: Electro-optic animated displays and indicators

IPC: G09F13/10

Granted: 1990-04-24
Abstract: Electro-optic Animated Displays and Indicator by David Makow Abstract In this invention, animation effects have been obtained in a device containing a light source illuminating a linear polariser producing plane polarised light which is rotated in an electro-optical cell/cells such as a Liquid Crystal or PLZT cell. The angle of the plane is changed at the required speed by a voltage applied to the electrodes of the cell; this voltage being generated in an electronic circuit or obtained from the output of a transducer or manually. The rotated plane polarised light is shining through a stationary set of at least two linear polarisers oriented at different angles and then through a screen containing the art work. The emerging lighted image is perceived by the viewer as a change or as an animated movement of the art work. Colour effects can also be obtained when a chromatic polariser or a chromatic retardation plate is used. In the prior art, the change of the angle of the plane polarised light was achieved by mounting the linear polariser on a mechanically rotated wheel. The introduction of electro-optical voltage controlled cells has many advantaged such as speed of response, illumination of moving parts, feasibility of new effects, and flexibility of design. The applications of this invention are in advertising and exhibition displays, animated signage, animated printed material, instrument readout indicators and monitors, works of art, and in the field of toys and games.

Abstract: "PERMEATION PROCESS FOR SEPARATING AMMONIA FROM A GAS MIXTURE"                      ABSTRACT OF THE DISCLOSURE         A process is provided for separating ammonia from an ammonia synthesis purge gas stream containing ammonia, hydrogen, and contaminant gases.   The process involves introducing the gas stream into a permeator equipped with a polysulphone amide gas separation membrane, to selectively permeate ammonia therethrough.   The gas stream is at a temperature less than about 0° C upon introduction to the permeation step.   The polysulphone amide membrane surprisingly exhibits high permeability to ammonia permeation (relative to hydrogen) at low temperature.   The ammonia is thus first separated by low temperature permeation and the hydrogen may then be recovered from the residue gas using a conventional membrane that exhibits high permeability to hydrogen.   The two-step permeation process removers ammonia and hydrogen in two separate streams and permits the use of a second stage membrane that would be deleteriously affected by ammonia in the hydrogen recovery step.
