Abstract: ABSTRACT OF THE DISCLOSURE:     For use in cancelling a distortion caused by multipath transmission to an original radio frequency pulse of an original pulse shape, a multipath canceller comprises a priliminary circuit for producing a distortionless pulse of the original pulse shape and a distortion cancelling circuit responsive to the distortionless pulse and each distorted pulse having the distortion for producing a distortion cancelled pulse at a correct pulse position which the original pulse would have if received through a direct path alone.  The preliminary circuit may comprise a memory for the distortionless pulse.  The distortion cancelling circuit may comprise an envelope detector for envelope detecting the distorted pulse to produce a detected pulse, a composer for composing the distortionless pulse with different amplitudes and pulse positions repeatedly into a composite pulse approximating the detected pulse, and a generator for generating the distortion cancelled pulse by using the distortionless pulse and a pulse position of one of the composite pulses that has an earliest occurrence.          Alternatively, the preliminary circuit may comprise DFT and IDFT circuits for processing the distorted pulse into the distortionless pulse.  The distortion cancelling circuit may comprise a cross correla-tor for the distorted and the distortionless pulses and an autocorrela-tor for the distortionless pulse.

Title: Electro-optic switching system using circularly  polarized light
Inventor: BUZAK THOMAS S
IPC: G02F1/1335

Granted: 1987-07-07
Abstract: Abstract of the Disclosure A method and an apparatus provide an optical switching system (100) which maintains essentially constant transmissivity at its maximum value and develops independent of viewing angle two system optical transmission states of substantially contaminant-free light.  The system includes first and second light gates (102 and 104) of which each has associated therewith contaminant light intensity patterns (48 and 66) with points of local maxima (54, 56, 58, 60, 68, and 70) and local minima (62 and 72) in two system optical transmission states.  Quarter-wave plates (134 and 136) are positioned between the light gates to develop circular polarization of light propagating between them.  The presence of circularly polarized light maintains the system transmissivity at its maximum value while the relative orientation of the light gates is changed to align their contaminant light intensity patterns to block the transmission of contaminant light, and thereby improve the viewing angle performance.

Abstract: DOPPLER SIGNAL FREQUENCY CONVERTER     ABSTRACT OF THE DISCLOSURE         A Doppler signal frequency converter for use in an apparatus used to detect and measure the velocity of movement of an object by picking up the reflections of ultrasonic waves beamed at the subject of examination. The converter is provided with one or a plurality of complex signal converters, and a complex multiplier which computes the conjugate and complex products of the complex signals.          The complex signal converter converts the Doppler signals to a plurality -- for example two -- complex signals which differ in frequency.  By carrying out computations based on the real and imaginary parts of the complex signals, the conjugate and complex products of the two complex signals are obtained.  These conjugate and complex products are Doppler signals having a frequency which enables a wide range of velocity components to be detected, the conjugate product enabling the velocity of a distant rapidly-moving object to be measured accurately, while the complex product provides accurate measurement of the velocity of a slow-moving object.

Abstract: ABSTRACT OF THE DISCLOSURE           A considerable portion of the gas developed by fermentation in an anaerobic purification equipment for waste water, together with buoyant sludge, is collected by at least one additional collecting system, before it may reach the upper part of the reactor.  This additional collecting system is fitted at a distance below the collecting system fitted as usual just below the level of one or more overflow gutters for purified water.  The additional collecting system has a hydraulic link with one or more rising pipes for raising the liquid sludge mixture by gas lift action.  The rising pipes discharge into a separation device from which one or more downpipes for returning separated liquid and sludge extend to the lower section of the reactor chamber.  As a result of the tranquility at the top and the turbulence near the bottom, a substantial increase of the load capacity of the equipment can be obtained.

Abstract: ABSTRACT     A ratchet system (10) includes a "T" shaped stop-engaging member (50) mounted in a plane (72) perpendicular to a rotating spindle (22) and parallel to a circular carrier member (28) having stop members (40) mounted on the periphery and rotating with the spindle (22).  The stem (52) of the "T" member (50) is rotatably mounted in housing (60) surrounding the spindle (22), and upon selective rotation the ends (54a, 54b) of the cross-bar (54) of the "T" member engage the stop members (40) to prevent rotation in a selected direction.  The cross-bar (54) transmits the engagement force directly to a recess (70) in the inner wall of the housing (60).  A hand-actuated knob assembly (82, 94) located outside the housing (60) is connected to the "T" member stem by a resilient bushing (100) which provides a restoring force to return the "T" member (50) to a stop engagement position following deflection by stop members (40) travelling in a direction counter to that intended to be prohibited.

Abstract: ALGIN/CALCIUM GEL STRUCTURED MEAT PRODUCTS    ABSTRACT      Structured meat products, particularly structured raw meat products, are prepared by mixing comminuted meat or trimmings with powdered sodium alginate and powdered calcium carbonate.  A slow release acid,  such as glucono-delta-lactone, citric acid, lactic acid and the like, can also be added.  The slow hydrolysis of the powdered form of such acids slowly lowers the pH of the meat to improve its flavor, but still ultimately produces enough hydrogen ions to stimulate the release of sufficient calcium ions from the calcium salt to accelerate formation of an algin/calcium gel.  In either case, after being formed into the desired shape, the meat is stored, usually under refrigeration, from about one to four days to allow the algin/calcium gel to set. Thereafter, the resulting structured meat product can be conveniently portioned, packaged and marketed as a refrigerated raw meat product, a frozen raw meat product, or precooked and marketed refrigerated or frozen.

Abstract: ABSTRACT INTERLACE TO NON-INTERLACE SCAN CONVERTER FOR RGB FORMAT INPUT SIGNALS A speed-up memory (22,24,26), converts interlaced RGB input signals to double line-rate (progressive scan) form. A vertical detail signal (S3) is derived from the RGB input signals before or after speed-up and a vertical peaking signal (S4) is derived from the detail signal. During the first read operation of the speed-up memory both signals (S3,S4) are added (84,86 with 32,42,52) to the speeded-up signals to effect a preshoot of the resultant signal, and during the second speed-up memory read operation only the peaking signal (S4) is added (32,42,52) to affect an overshoot of the resultant signals whereby alternate lines of the converted RGB signals exhibit enhanced vertical detail.

Abstract: SYSTEM AND METHOD EMPLOYING NONLINEAR INTERPOLATION FOR THE DISPLAY OF SURFACE STRUCTURES CONTAINED WITHIN THE INTERIOR REGION     OF A SOLID BODY                 ABSTRACT OF THE DISCLOSURE           A method and apparatus for displaying three dimensional surface images includes the utilization of a case table for rapid retrieval of surface approxima-tion information.  Eight cubically adjacent data points associated with a given voxel element are compared with a predetermined threshold value or range to generate an eight bit vector.  This eight bit vector is employed to rapidly produce vector lists of approximating surfaces. A non-linear interpolation operation is performed so as to more closely approximate the desired surface and to provide more accurate representations of vectors normal to the desired surface.  The accurate representation of these normal directions provides means for accurately representing shading information on a display screen. The method and apparatus of the present invention are particularly useful for the display of medical images both from x-ray generated data and from data generated from various other sources including magnetic resonance imaging and positron emission tomography.  The present invention provides a means for rapid generation of three dimensional images so as to enable interactive use by medical practitioners.
