Abstract: ABSTRACT A freeze-dried soluble coffee product in the form of particles or granules and having a microporous structure is prepared by prechilling a metal plate in a liquid refrigerant, immersing the plate in aqueous extract of coffee solids, reimmersing the plate in a liquid refrigerant, removing the frozen particles in the form of flakes from the plate, grinding and freeze-drying the flakes to produce frozen extract particles with reduced entrainment losses. The product so prepared has a unique porosity and is capable of sorbing, retaining and releasing volatile aromatic compounds.

Abstract: Abstract  of the Invention Modem apparatus comprising circuitry featuring two loosely coupled microprocessors; and a receiver featuring means for inhibiting the updating of adaptive equalizer coefficients in the presence of periodic data, improved automatic gain control and carrier detect/loss circuitry, improved circuitry for filtering and demodulating received signals, and improved timing recovery and timing initialization circuitry.     Background of the Invention This invention relates in several aspects to modem apparatus in which a modulated carrier signal represents digital bits, and in one aspect to modem apparatus in which a received, modulated double sideband carrier signal, representing digital bits, is converted to a stream of digital samples which are then filtered and demodulated.         Recently, efforts have been made to use programmable microprocessing circuitry to carry out certain modem functions, e.g., as described in Walsh et al. U.S. Patent No. 4,085,449.         P. J. Van Gerwen, N.A.M. Verhoeckx, H. A. Van Essen and F.A.M. Snijders, "Microprocessor Implementation of High-Speed Data Modems", IEEE Transactions on Communica-tions, Vol. COM-25, No. 2, February 1977, pp. 238-250 shows a microprocessor implemented modem receiver wherein an incoming QAM signal passes through two digital phase-splitting filters prior to demodulation.

Abstract: HYDROCRACKING OF HEAVY OILS IN PRESENCE OF PYRITE PARTICLES     Abstract of the Disclosure An improved process is described for the hydrocracking of heavy hydrocarbon oil, such as oils extracted from tar sands.  The charge oil in the presence of an excess of hydrogen is passed through a tubular hydrocracking zone, and the effluent emerging from the top of the zone is separated into a gaseous stream containing a wide boiling range material and a liquid stream containing heavy hydro-carbons.  According to the novel feature, the charge stock is in the form of a slurry of heavy hydrocarbon oil and finely divided pyrite.  The presence of this pyrite in the charge stock serves to greatly reduce coke precursors and thereby prevent the formation of carbonaceous deposits in the reaction zone.

Abstract: DIRT REMOVING GRID SYSTEM FOR FLOORS      Abstract A floor grid is provided for a trafficway for removing debris from traffic passing thereover.  The grid comprises a support structure below the surface of the trafficway, a plurality of spaced tread rails defining an upper surface which is generally flush with the surface of the trafficway and being supported by the support structure, and a plurality of traverse spacer bars or channels positioned immediately beneath the tread rails.  Each tread rail is secured to each spacer channel by a bolt where both cross.          Each bolt has a head which is received in and is slidable, when the bolt is not tightened, along a pair of confronting slots in an associated tread rail.  Each of the slots has a flat vertical surface which respectively butt against a pair of flat vertical surfaces of the bolt head preventing rotation of the bolt relative to the tread rail.  Preferably the slots are just high enough to snugly receive the bolt heads.  Feet extend outwardly from the lower end of each tread rail and engage the spacer channels.  The feet in conjunction with the tightened bolts resist movement of the tread rail with respect to the spacer channels.  The tread rails and spacer channels together form an insert which is easily removable for repair or cleaning.  Cushions are provided between the tread rails and support structure to absorb vibration and impact.

Title: Adjustable clamping wedge system for cutting insert  of a milling cutter
Inventor: ERKFRITZ DONALD S
IPC: B26D1/12
Filed: 1981-08-21
Granted: 1984-01-03
Abstract: ABSTRACT OF THE DISCLOSURE A milling cutter includes an array of pockets each having radially extending side walls and a base wall from which radially projects an elongated locating rail. A safety wedge has one surface in engagement with one wall of the pocket and its opposed surface in engagement with one surface of a cutting insert.  The latter includes a central hole through which extends a projection extending from the safety wedge.  One edge of the cutting insert engages the locating rail, while the opposite surface of the cutting insert is engaged by a wedge surface of a wedge assembly which is connected to the body of the cutting tool, and is selectively operable for shifting of the wedge assembly into wedging engagement with the cutting insert.  By this arrangement, the cutting insert is clamped intermediate the safety wedge and the wedge assembly, and the edge of the cutting insert bears against the locating rail.   As the milling cutter is rotated, the hard wedge assembly is behind the cutting insert and thus provides protection to the cutter body in the event of a wreck that would destroy the carbide cutting edge of the cutting insert. In addition, the hard safety wedge disposed ahead of the cutting edge protects the body from chip-erosion.

Abstract: PHASE DETECTORS FOR DETECTING A MUTUAL PHASE DIFFERENCE        BETWEEN TWO SIGNALS     ABSTRACT OF THE DISCLOSURE         A phase detector for detecting a mutual phase difference between two signals, such as first and second microwave signals, comprises first and second signal paths for being supplied with first and second input signals of the same frequency, respectively, and providing with a predetermined additional mutual phase difference between the first and second input signals at their output ends and a field effect transistor having a pair of input electrodes connected to the output ends of the first and second signal paths, respectively, and an output electrode from which an output signal representing a mutual phase difference which the first and second input signals have originally therebetween is derived.  The first and second input signals at the input electrodes of the field effect transistor have the original mutual phase difference which is to be detected and the predetermined additional mutual phase difference added by the first and second signal paths therebetween.  The field effect trasistor is biased to operate with a gate bias voltage nearly equal to a pinch-off voltage thereof.  In order to establish such biasing state without reducing the operational gain of the field effect transistor, a biasing resistance connected to the source of the field effect transistor is selected to be low and a cuurent source is provided for supplying an external biasing current to the biasing resistance, thereby to produce the gate bias voltage required.

Abstract: ABSTRACT         Described herein are "polydomas", the product of the fusion of a hybridoma with a B-lymphocyte or another hybridoma. The polydomas produce a hybrid monoclonal antibody having a dual specificity against two different antigenic determinants. Also described are immunodiagnostic and immunotherapeutic pro-cesses which utilize the hybrid monoclonal antibodies or other antibodies having a dual specificity.  In those processes, one specificity of the antibody is directed against a target antigen and the other against a moiety which permits a diagnosis to be made or which delivers an agent lethal to the target antigen or associated tissue.
