Abstract: CCD COMB FILTER AND DEMODULATION SYSTEM .            ABSTRACT OF THE DISCLOSURE     A CCD comb filter and color demodulation system is described for use in a color television receiver.          The system includes a CCD comb filter receiving a video signal having interleaved luminance and color components, the latter components including a color subcarrier at a nominal frequency.  Preferably, the comb filter includes but two CCD devices which receive the input video signal and apply their sampled outputs to a summer to develop combed luminance components and combed color components which occupy different frequency bands.  The combed color components include a color subcarrier and side-bands which are translated upward in frequency by a given multiple of the nominal subcarrier frequency.  The latter components are applied to a pair of CCD output filters which are clocked to sample the color components at the given multiple of the nominal subcarrier frequency for developing baseband demodulated color signals.  The preferred embodiment also provides on-chip vertical peaking of the combed luminance components.

Abstract: ABSTRACT     A well jar having an elongated body with an axial passageway and threaded connections for assembly into a string of well pipe.  The body has a tubular mandrel slideably mounted within a tubular barrel with the annulus therebetween exposed to well fluid.  Fluid seals in the annulus provide an isolated chamber containing a latch whereby the mandrel and barrel are selectively released for delivering an impact to the wellpipe.      The improvement to the jar comprises a plurality of elongated, resilient vibration snubbers integrally carried by the mandrel and aligned longitudinally in the annulus between the mandrel and the barrel.  The snubbers slideably engage the barrel throughout its telescopic movement along the mandrel.  The snubbers are circumferentially spaced apart about the mandrel with the in-tervening spaces forming flow channels in the annulus to ac-comodate well fluid flows when the jar is mounted in the string of well pipe being rotated in the well bore.     In another embodiment, as a subcombination, an elon-gated, resilient vibration snubber is designed for mounting in a flat bottom groove in a cylindrical metal surface on a well jar.          The snubber has a rectangular body of resilient synthetic rubber integrally bonded to a thin metal base.  The base and body are provided with one or more transverse apertures to accomodate threaded fasteners.  The body has a curved surface on the side opposite to its mounting on the base.  Preferably, the snubber is formed of a synthetic rubber with a hardness of about 80 durometer shore-A.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for preparing a novel highly oil absorbent peat product useful to control oil spills for oil spill clean-up.  The process involves first preparing an initial mixture by mixing peat with an alkaline earth metal basic product, e.g., a magnesium/calcium hydroxide lime substitute material, e.g., at a ratio of 15:1 to 45:1.  Then, that mixture is partially dried by heating either directly in an oven or a microwave oven or indirectly by a heat exchanger for a predetermined period of time, e.g., at a maximum temperature of 300°F. for a maximum time of 15 minutes.  Then, a further mixture is prepared by mixing addi-tional such basic material with the partially dried peat;  and further heating the further mixture during a second stage until the peat has the desired moisture content magnesium/calcium hydroxide lime substitute material with the partially dried peat, e.g., at a ratio of 10:1 to 20:1.          The further mixture is then heated, either directly in an oven or a microwave oven or indirectly by a heat exchanger, e.g., at a maximum temperature of 300 F. for a maximum time of 15 minutes until the peat has the desired moisture content, e.g., 5 - 10%.  This novel product can absorb some 20 times its own weight of oil which makes it very advantage-ous for cleaning up oil spills either on land or on water.  Also, the oil in the present absorbent used to clean the oil spills may be easily removed.

Abstract: AUTOMATIC DOOR OPERATOR                 ABSTRACT OF THE DISCLOSURE      A door operator of electromechanical character for utilization with swing-mounted doors is provided in a self-contained unit for mounting as a part of a door frame of for attachment to existing doors and frames.  The opener has a door driving shaft mounted for rotation about a vertical axis and connectable to a door for closing and opening of the door when rotated, and a transmission interconnecting a prime mover and door driving shaft for rotation to open the door upon selective delivery of power by the prime mover.          A pinion interconnected with the shaft meshes with a rack gear for shifting of the rack gear about a longitudinal axis in response to rotation of the shaft.  The unit includes a module of interchangeable character having a preloaded spring and configured for the intended direction(s) of rotation of the door for opening.  The spring receives energy from the rack gear upon door opening and then transfers the stored energy to the rack gear upon cessation of delivery of power by the prime mover for producing rotation of the shaft in the opposite direction to close the door while returning power to the prime mover, which is preferably an electronically driven and controlled d.c. motor.  The rack gear and spring module permit rotation of the shaft also in a direction for emergency opening of the door.

Abstract: ABSTRACT             ALKALINE ELECTRIC STORAGE CELLS     An alkaline electric storage cell comprises a container 2 within which are positive and negative pocket plates 4 and 6 separated by composite separators 8. Each separator has a lower portion 30, 36 which is of conventional ladder type having a substantially open area and an upper portion which is a strip 38 of absorbent fibrous material.  The cell is filled with electrolyte up to a level 44 which is slightly above the bottom of the strips 38.  The high discharge rate voltage of the cell is scarcely impaired by comparison with a conventional cell, but the oxygen that is evolved at the end of charge is recombined at those portions of the negative plates which are above the electrolyte level but retained moist with electrolyte by the absorbent strips 38.  The cell thus loses no electrolyte and is of no-maintenance type at charging rates of up to C/60 or more.

Abstract: Abstract Disclosed is a dry or wet milling process for making fermentable sugars and high-protein products from starch bearing material, characterized by saccharification of the starch followed by recovery of fiber all other non-protein materials and of destarched protein as separate products, leaving a sugar solution that is essentially free of insoluble materials.  The sugars are fermented to ethanol and carbon dioxide by the action of added yeast.  After fermentation,      ?east is recovered for use in fermenting additional quantities of sugars supplied either for batch or continuous processing.  The alcohol is then removed leaving a dilute solution of unfermentable soluble materials, and this liquid, in whole or in part, is recycled to preceding steps in the process.
