Title: Method for operating a networked computer system to minimize data conversion overhead
Inventor: CARPENTER RICHARD A
IPC: G06F15/16
Filed: 1992-03-12
Abstract: ABSTRACT OF THE DISCLOSURE A method is provided for operating a networked computer system including a plurality of computers, some of which exhibit different data formats and some of which exhibit identical data formats.   Prior to sending  a message  from  a  sending  computer  to  a receiving  computer  on  the  network,  the  sending computer sends its data format requirements to the receiving computer.   When  the  receiving computer receiving the message from the sending computer, the message is converted from the data format of the sending computer to the data format of the receiving computer  if  the data  format  requirements  of  the sending  and receiving  computers  are  found to  be different.  The converted message thus generated is then passed to application software.  If however, the data format requirements of the sending and receiving computers are found to be the same, then the received message is passed to application software without conversion.

Title: Power Supply and Oscillator for a Computer System Providing Automatic Selection of Supply Voltage and Frequency
Inventor: FAIRBANKS JOHN P
IPC: G05F1/565
Filed: 1990-06-28
Abstract: Disclosed is a power system (13) for use with a computer, the power system (13) having incorporated in it circuitry for auto-matically varying the supply voltage (VDD) output to the computer system based upon the magnitude of the current being suppli-ed to the computer by the power system.  Also included in the computer system is a variable frequency clock circuit, the frequency of which changes based upon the supply voltage (VDD) produced by the power system (13).  This permits, during computer sys-tem operation where low voltage and low clock speeds will be sufficient to provide the performance needed achievement of a power saving since both the voltage and frequency at which the system operates is reduced, thereby markedly reducing the power consumption.

Title: Control circuit for an imager used in a document processing machine
Inventor: LUCKHURST GRAHAM
IPC: H04N1/401
Filed: 1992-04-06
Abstract: Abstract Of The Disclosure A control circuit for processing image data received from an imager, like a CCD, with the circuit providing automatic compensation for those factors usually associated with imaging systems.  The imager generates image data for a predetermined number of pixel positions in a scan line at a predetermined rate for a document being moved relative to the scan line.          This image data is processed, amplified, and fed (at the predetermined rate) into a flash A/D converter used in the circuit.  Offset and gain compensation data are supplied as reference levels to the converter at the predetermined rate to provide offset and gain compensation for each pixel position in the scan line.          This ensures predictable post processing performance with regard to binarization, compression, and machine reading plus a consistent and undistorted gray level representation of the imaged document.

Title: Polymerization of vinyl chloride
Inventor: SEIICHI MASUKO
IPC: C08F14/06
Filed: 1990-12-28
Abstract: ABSTRACT  In a novel method of homo- or copolymerization of vinyl chloride, a specified coating agent is applied on the surfaces of the portions which will become into contact with the vinyl chloride monomer during the polymerization process. The coating agent is in a form of an aqueous solution of a modified condensation product of phenol and aldehyde, the pH of the solution being adjusted in a range that the product is dissolved at an ambient temperature upon coating of the solution and separates out of the solution upon being heated on the surfaces.  The wall surface of the polymerization tank and the like is then coated with a thin film of the coating agent having a uniform thickness and being strongly adhered to the wall surface, thereby providing an excellent effect of preventing adhesion of the product polymer to the wall surface.

Abstract: A cell exchanging apparatus which distributes cells input through a plurality of input lines to output lines by destination for output.  Without stopping the operation of the cell exchanging apparatus, active and standby cell switches of the cell exchanging apparatus can be changed over.  The cell exchanging apparatus comprises a first and second cell switches, input selectors for feeding input cells only to either of the first and second cell switches, and output selectors for outputting cells output from either of the first and second cell switches to an external system.  When a change-over is instructed by a system change-over signal, the input selectors start to feed input cells into the cell switch in the standby mode.  When detecting completion of cell output operation from the active cell switch, the output selectors select a new active cell switch.  Upon detection of completion of cell output operation from the former active cell switch, a controller sends an output permission signal to the new active cell switch.          Resultantly, the new active cell switch starts to output cells to the output selectors which then output the cells to an external system.

Title: Stage cementer and inflation packer apparatus
Inventor: STREICH STEVEN G
IPC: E21B33/127
Filed: 1993-07-28
Abstract: Abstract Of The Disclosure A stage cementer and inflation packer apparatus.   The apparatus comprises a mandrel with an external closing sleeve and an operating sleeve interlocked therewith.   Below the operating sleeve is an opening sleeve.  The opening sleeve is mechanically acutated by a pump-down plug in a plug-operated embodiment or by a differential pressure acting on the opening sleeve in a hydraulically operated embodiment, to actuate the opening sleeve to allow inflation of the packer element.  A back check valve prevents the packer from deflating.  After the packer is inflated, additional pressure is applied which ruptures a rupture disc to open a port to the well annulus above the set packer element.  Cementing may be carried out through this port, and after the cementing operating, a plug engages the operating sleeve to move the operating sleeve in the external closure sleeve, thereby closing the cementing port.  After cementing is complete, the center components of the apparatus may be drilled out, leaving the external closure sleeve to permanently seal the cementing port.
