IPC: F42B7/04
Filed: 1990-01-19
Abstract: Abstract of the Disclosure A tracer shotgun shell includes an improved tracer element and a single, integral wad member, which supports the tracer element within a shot charge.  The tracer element is in the form of a spherical ball with a cylindrically-shaped, radially extending tail.  A hole is formed through the tail and into the ball, past its center, and an igniter compound is positioned centrally within the ball.  A preferred form of the igniter compound includes a mixture, by weight, of 87% barium peroxide, 11% magnesium, and 2% strontium nitrate.  The single, integral wad member includes a transverse base section, having a downwardly extending perimetric flange; an upper transverse section; and a stem interconnecting and spacing the two sections.  A tracer element mounting platform is formed centrally atop the upper transverse section, and extends into the charge of shot 90 as to permit shot to laterally encircle the platform.  The tracer element mounting platform incorporates a centered concave depression corresponding in shape to the outer surface of the tracer element spherical ball, which provides extended surface contact between the tracer element and its mounting platform.  A hole is centrally formed within the concave depression, to accept the tail of the tracer element, which connects with an ignition passage extending axially through the wad member.

Title: Modular continuous vapor deposition system
Inventor: MADAN ARUN
IPC: H01L21/00
Filed: 1990-02-06
Abstract: A MODULAR CONTINUOUS VAPOR DEPOSITION SYSTEM                 ABSTRACT           A modular continuous vapor deposition system for the fabrication of semiconductor devices having a plurality of deposition modules isolated from each other by isolation modules which prevent the cross contamina-tion of the different processing gases used in the deposition modules.  Each of the deposition modules has a flow of a decomposable processing gas therethrough at a desired pressure, and means for generating a continu-ous glow discharge.  The glow discharge decomposes the processing gas to deposit a layer of amorphous semicon-ductor material on the discrete substrate sheets as they are transported through each of the deposition modules. A plurality of gate valves effectively seal the inter-faces between adjacent modules to isolate them from their immediate neighbors and are opened in a predeter-mined sequence to allow the substrate sheets to be transported from one module to the next.  The isolation modules are connected to a vacuum source and a back-fill gas source.  A control coordinates the activation of the gate valves, the vacuum source and the back-fill gas source so that the substrate sheets can be uninterrupt-edly transported through the system while maintaining the glow discharge continuous and gas pressure in each deposition module at the desired pressure.

Filed: 1990-09-06
Abstract: A compact disc program display mechanism in which album covers are displayed on pages similar to a book presentation; each album having a selection indicia visually associated therewith for selection by the customer.  The several pages are turned in response to energization of an electrical drive motor and gear train, controlled manually by customer accessible push button switches or automatically by a programmed microprocessor. Each energization of the motor serves to pivotally turn a pair of pages in one direction with the indexing movements of the pages being controlled by an opto-switch and the microprocessor for deenergizing the drive motor at predetermined page movement.  Reverse movement of the pages is also conditioned by the opto-switch which signals the micro-processor to reverse the rotational direction of the drive motor.  Each page displays album covers on both its front and back sides for customer viewing.

Abstract: VERY LOW TEMPERATURE CASTING OF CONTROLLED RELEASE MICROSPHERES             Abstract of the Invention A process for preparing microspheres using very cold temperatures to freeze polymer-biologically active agent mixtures into polymeric microspheres with very high retention of biological activity and material. Polymer is dissolved in a solvent together with an active agent that can be either dissolved in the solvent or dispersed in the solvent in the form of microparticles. The polymer/active agent mixture is atomized into a vessel containing a liquid non-solvent, alone or frozen and overlayed with a liquified gas, at a temperature below the freezing point of the polymer/active agent solution. The cold liquified gas or liquid immediately freezes the polymer droplets. As the droplets and non-solvent for the polymer is warmed, the solvent in the droplets thaws and is extacted into the non-solvent, resulting in hardened microspheres.
