Abstract: Novel compositions comprising a high concentration of one or more extended chain homopolymer, copolymer, or block polymer and certain polyphosphoric acids are prepared. Such compositions are optically anisotropic (liquid crystalline), capable of exhibiting excellent cohesive strength, and are especially suited to the production of high molecular weight ordered polymer fibers by dry-jet wet spinning. These liquid crystalline compositions are capable of being drawn through long air gap distances and spun at exceptionally high spin draw ratios. Fibers, films and other articles formed from these liquid crystalline compositions exhibit exceptionally high physical and heat resistant properties.

Abstract: SYSTEM FOR ENABLING DESCRAMBLING ON A SELECTIVE-SUBSCRIPTION       BASIS IN A SUBSCRIBER COMMUNICATION NETWORK          ABSTRACT OF THE DISCLOSURE    A  system  in   a  subscriber  television  network  for enabling  descrambling  of a received scrambled signal on  a prepaid basis and/or an impulse-purchase basis.   A received mask  signal  uniquely related to the  scrambled  signal  is compared  with  a received authorization  signal  indicating whether   the  subscriber  is  authorized  to  receive   the scrambled signal on a prepaid basis and a prepaid signal for enabling  descrambling is provided when the compared signals match,   A  not-prepaid signal is provided when they do  not match,  A  received  cost signal indicating the  charge  for descrambling  the  scrambled signal and  a  received  credit signal  indicating  the subscriber's accumulated credit  are processed   with  reference  to  a  stored  record  of   the subscriber's prior accumulated charges to determine  whether the  subscriber  has sufficient available credit to pay  for descrambling of the scrambled signal.   If a program is  not prepaid   and  if  sufficient  credit  is   available,   the subscriber  is given  the option of causing the signal to be descrambled  on  an impulse-purchase  basis.  To  prevent  a subscriber  from obtaining descrambling through such  deceit as  changing  the mask,  authorization,  cost and/or  credit signals,  these signals are processed with key signals which are  used  in  scrambling and  descrambling  the  television signal  such  that descrambling is prevented if any  of  the mask et al signals is changed.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for recording a color video signal in which a luminance signal and a chrominance signal are recorded on separate channels and at least two chrominance component signals are compressed in timebase and alternately arranged in turn to be recorded on one track as the  chrominance signal is disclosed.  This apparatus includes timebase compressing and expanding circuits provided respectively for the chrominance compo-nent signals and for producing timebase compressed chrominance component signals by writing the chrominance component signals by a first signal and by reading them by a second signal with the frequency integer times as high as that of the first signal and a coupling circuit for simultaneously supplying the chrominance component signals, which are being read out from the output terminals of the timebase compressing and expanding circuits by the second signal, to the input terminals of the timebase compressing and expanding circuits, whereby the timebase compressed chrominance component signals are written in the timebase compressing and expanding circuits by the second signal.  In this case, when succeeding chrominance component signals are written in the timebase compressing and expanding circuits by the first signal, the timebase compressed chrominance component signals rewritten in the timebase compressing and expanding circuits are read out therefrom by the first signal so as to produce normal chrominance component signals.

Title: Hydraulic pressing shoe, its use and a method for operating it
Inventor: DAHL HANS K
IPC: D21F3/02
Filed: 1985-11-20
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE     A pressing machine includes a roller and a pressing shoe which can be moved towards and away from the roller to exert pressure on the roller or on a material in a gap between the shoe and the roller.  The shoe is mounted in a pressure chamber to which hydraulic pressure medium can be supplied to move the shoe.  Upon movement towards the roller, the shoe applies pressure over a zone extending for a part of the circumference of the roller.  Means is mounted on the pressing shoe for altering the length of this zone in the circumferential direction of the roller.  To this end, the shoe may have two movable jaws which establish said zone, the jaws being movable by adjusting means over a cylindrical surface of said shoe which has substantially the same centre of curvature as the roller.  The pressing shoe is particularly advantageous in a paper machine for dewatering a web of paper or for supporting the rollers of a rolling apparatus.

Title: Electrostatic pattern-coupled digitizer
Inventor: DHAWAN SATISH K
IPC: G06F3/033
Filed: 1986-02-20
Granted: 1990-11-13
Abstract: Abstract A digitizer in which position of a free moving cursor or stylus over a digitizing surface is determined by electrostatic coupling of the cursor with three coplanar electrodes imbedded in the digitizing tablet.  The electrodes consist of a repetitive sawtooth pattern to determine position in one axis, the sawtooths interleaved with progressively wider, repetitive stripes to determine position in another axis.  The third electrode covers the remainder of the coplanar surface area.  Only three electrode signals are required to be electronically processed to determine absolute vertical and horizontal position of the cursor over the digitizing tablet by a ratiometric measurement. The signals from the electrodes are processed synchronously to reject noise.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of controlling the profile of a sheet material while it is rolled between upper and lower working rolls that can be shifted axially and in opposite directions.   The profile of each working roll that varies during the time interval between one chang-ing of the working rolls and another is determined.  so the basis of the determined roll profiles, the relation-ship between the amounts of shifting in the roll posi-tion and the configuration of the gap between the upper and lower rolls in the axial direction is determined, so as to determine the amount of shift in the roll position that will provide the smoothest possible configuration for the gap in the axial direction within the area of contact between the work and the working rolls. The upper and lower rolls are shifted axially in accordance with the determination of how to provide the smoothest possible configuration for the gap between rollers.

Abstract: DUAL DIAPHRAGM DIFFERENTIAL PRESSURE TRANSDUCER            Abstract of the Disclosure A corrosion proof differential pressure transducer includes a central disk and two thin diaphragms mounted close to but spaced from the disk on both sides thereof, with the diaphragms being intercoupled to move together. This may be accomplished, for example, by a rod passing through a hole in the center of the central disk which is secured to each of the diaphragms; or by a fluid such as silicone oil in the space between the diaphragms and flowing through one or more holes through the central disk.  At least one of the diaphragms, the central disk and the rod (where one is used)  are formed of alumina, quartz,  or  other  inert,  insulating  material  having substantially zero mechanical hysteresis.   One of the diaphragms may be a thin, tough,  flexible insulating membrane.   Conductive plates providing variable  capa-citance with changes in pressure may be mounted on the inner surface one or both of the diaphragms and on the facing surface of the central disk.   Alternatively, resistive elements bonded to the inner surfaces of the diaphragms  may  be  employed  as  the  pressure  sensing elements, as their resistance changes with flexing of the diaphragms.  A housing and associated gaskets direct pressures from two different fluids to the two dia-phragms, so that the differential pressure is measured.
