Abstract: Hybrid resins result from the combination of urethane and unsaturated polyester technology.  Improved resin casting and laminate properties are obtained when polyalkylene terephthalate unsaturated polyesters are employed, in lieu of the isophthalic polyesters of the prior art.  Especially notable are improved heat distortion temperatures which exceed substantially those of the isophthalic based resins.  The economics of using such terephthalate resins is demonstrated.  Also within the scope of the present invention is the use of secondary hydroxyl compounds in the preparation of the polyesters. It has previously been believed that such compounds led to embrittlement of the final hybrid.

Title: Apparatus and method for flow control
Inventor: BRECKNER RAYMOND A
IPC: F04B15/02
Filed: 1989-03-16
Granted: 1992-06-16
Abstract: APPARATUS AND METHOD FOR FLOW CONTROL            ABSTRACT OF THE DISCLOSURE         The invention provides an apparatus and method for handling a solid/liquid mixture, for example for conveying fish immersed in a fish/water mixture.  The apparatus has a receiving chamber to receive the mixture through an inlet valve when the chamber is subjected to low pressure, and to discharge the mixture through an outlet valve thereof when pressure in the chamber is increased.  A quantity sensor is responsive to a predetermined quantity of mixture within the chamber to isolate the chamber from low pressure when the predetermined quantity is reached.  The inlet valve is positioned adjacent an upper portion of the chamber above a maximum upper level of mixture within the chamber, and has seat clearing structure to clear the inlet valve seat of solids when flow therethrough ceases.  An inlet flow sensor is responsive to inlet flow of mixture through the inlet valve and raises pressure in the chamber when the flow therethrough stops, to provide time for solids to clear the inlet valve before closure thereof.  The quantity sensor also has a mode selector for selecting mode of operation of the apparatus which is responsive to quantity of mixture and controls pressure changes within the chamber.  A valve/switch which controls actuation of controls for changing pressure within the chamber is magnetically responsive to flow sensors disposed within inlet and outlet ducts to permit actuation of the valve/switch without mechanical contact therewith.  This isolates the valve/switch from contamination with the mixture in the duct and vice versa.

Abstract: Bioparyl is obtainable by a disclosed extraction hydrolysis and purification procedure applied to golden autumn leaves of the Gingko biloba tree. Bioparyl plays an important role in the regulation of the activity of certain enzymes, particularly ribonucleases (RNases), implicated in the fundamental mechanism of gene expression. It is low in or free from toxic or side effects in healthy animals, and can be used to ameliorate several pathogenic conditions.  Bioparyl is effective in preventing or reversing fibrosis in various tissues, including the lungs and skin, engendered by radiation or chemotherapy. It reduces abnormally high concentrations of gamma-globulins and immuno-globulins found in certain inflammatory or auto-immune diseases, including Acquired Immune Deficiency Syndrome disease (AIDS).  In patients with leukemia or solid cancers, Bioparyl normalizes the activity of ribonucleases.

Abstract: MICROINSTRUCTION ADDRESSING IN HIGH-SPEED CPU         ABSTRACT      A memory stack used for storing microinstruction addresses in a pipelined CPU is constructed as a last-in, first-out memory using a stack pointer which applies a read control to one location of the stack and applies a write control to the next higher location.  An uncondi-tional read and write is done every machine cycle, before a microinstruction could be decoded, then the data on the read bus, or data from the write bus, is used and the pointer is incremented or decremented if a stack Push or Pop is decoded.  These correspond to a Call or Return microinstruction.  Thus the delay in decoding the micro-instruction does not prevent completion of the stack operation in one machine cycle.

Title: Polymeric ore agglomeration aids
Inventor: GROSS ANTHONY E
IPC: C22B1/244
Filed: 1989-08-21
Granted: 2001-07-10
Abstract: Low grade gold and silver ores are leached by spray-ing barren cyanide solution onto a large heap of ore. As the solution percolates through the heap, the precious metal is dissolved out of the ore. The resulting pregnant solution is then collected for further processing. A major problem is segregation of fines in building the heap and migration of fines during percolation which results in channeling and/or blinding. To overcome the problem, the heap of ore is treated with an agglomerating agent which is a water-soluble vinyl polymer having a molecular weight of at least 500,000.

Abstract: PROFILE TAILORED TRENCH ETCH USING A   BOTH ISOTROPIC AND ANISOTROPIC ETCHING IS ACHIEVED BY VARYING THE AMOUNT OF OXYGEN                    ABSTRACT OF THE DISCLOSURE         A dopant-opaque layer of polysilicon is deposited on gate oxide on the upper substrate surface to serve as a pattern definer during fabrication of the device.  It provides control over successive P and N doping steps used to create the necessary operative junctions within a silicon substrate and the conductive structures formed atop the substrate.  A trench is formed in the upper silicon surface and a source conductive layer is deposited to electrically contact the source region as a gate conductive layer is deposited atop the gate oxide layer.  The trench sidewall is profile tailored using a novel O2-SF6 plasma etch technique.          An oxide sidewall spacer is formed on the sides of the pattern definer and gate oxide structures, before depositing the conductive material.  A planarizing layer is applied and used as a mask for selectively removing any conductive material deposited atop the oxide spacer.  The polysilicon layer on the oxide is reduced in thickness during trenching so that any conductive material deposited atop the spacers protrude upward for easy removal of excess, conductive material.  The sidewall spacers can be sized, either alone or in combination with profile tailoring of the trench, to control source-region width (i.e., parasitic pinched base width) and proximity of the source conductor to the FET channel.  Electrical contact between the source conductive layer and the source regions is enhanced by forming a low-resistivity layer between them.

Abstract: Synchronization between a transmitter and a receiver is effected by encoding and transmitting a synchronization pulse as a series of m first waveforms followed by a series of n second waveforms. The first and second waveforms are of the same duration and are transmitted in phase with each other; and m and n are positive real numbers, with m greater than one. The second waveform is different from, and preferably negatively correlated with, the first. When the receiver detects a series of first waveforms in the received signal, it locally generates a series of (either first or second) waveforms and correlates the locally-generated signal with the received signal. A change in correlation is detected as the synchronization pulse.

Abstract: A reclining seat support (3) and a backrest support (4) are hinged on a chair frame with a support part (1) via a lever (7) by means of hinges (5, 8). Coupled to the backrest-side end of the seat support (3) is a link chain (15) which is connected at its other end to a slide (20) and a backrest (21). The link chain (15) causes the slide (20) to be moved downwards with the backrest when the chair is reclined. By this means, the pulling-out effect during the transition from the normal position into the reclined position of the lever is eliminated. However, if the chair frame is used as a chair without a link chain (15), although slightly less seating comfort is achieved by the reclining seat support, the expenditure is correspondingly less. <IMAGE>
