Abstract: ABSTRACT OF THE DISCLOSURE          Comminuted fat and comminuted lean meats with ap-propriate additives, are pumped through separate manifolds to a die.  The die has various partitions or dividers and the fat enters the rear of the die and is shaped thereby.          The lean meat is extruded into the fat as it passes through the die and is shaped by the partitions.  The resultant slab is processed and then sliced to provide bacon analogue pro-duct with the various layers of lean meat being situated within the fat forming the remainder of the slab.  In another embodiment, the lean meat is pumped through a die at the rear of the machine and through shaped elements.  The fat is pumped around the elements whereupon the mass is extruded from the machine.  This permits islands of lean meat to be situated in the fat as well as lean strata partially or wholly on the outside of the slab.

Abstract: ABSTRACT OF THE DISCLOSURE       Two coaxial lines mounted orthogonally to each other and within a common shield to form a doubly balanced heter-odyne converter, the shield being connected from a first to a second point on each line and the outer conducter of each line being discontinuous at an intermediate point inside the shield.  The intermediate terminals can be connected to opposite terminals of a four-diode bridge mounted between baluns which are formed by the shield and the lines.  A heterodyne output signal is derived at the intermediate terminals of one of the coaxial baluns by means of two quarter wave lines which are connected at their ends remote from the balun to form a heterodyne output terminal.  The coaxial balun is capacitively coupled to the joint shield at the first and second points to avoid shorting the heterodyne output circuit.

Abstract: Abstract of the Disclosure Apparatus for heating the outer surface of an object such as a loaf of bread.  The object is conveyed through a heating chamber which has a plurality of aper-tures therein.  A plurality of laser beams of a wave-length that is readily absorbed by the outer surface of the object are generated and each beam is directed through a respective aperture in the chamber.  Each beam entering the chamber is diverged to scatter the beam and spread the energy contained therein out over a wider area than that in which the energy is initially contained.  The divergent beams are directed into a predetermined zone within the chamber through which the object must pass and the laser radiation within the zone strikes the outer surface of the object and is absorbed thereby to heat the outer surface.

Abstract: LIQUID SPREADER CONTROL SYSTEM             Abstract of the Disclosure An automatic control system for use with a vehicular liquid sprayer of the type which pumps the liquid to be sprayed at a desired pressure to a plurality of nozzles which dispense the liquid at a predetermined desired density relative to the area being sprayed, with the density being a function of a plurality of liquid spraying parameters which may vary from one spraying application to another or from time to time during a given spraying application.  A pressure transducer senses the pressure of the liquid supplied to the nozzles and develops a corresponding electrical liquid pressure signal.          A ground speed sensor measures the speed of the vehicular sprayer and develops a corresponding electrical ground speed signal.  Programming means are coupled to the ground speed sensor for selectively modifying the ground speed signal to obtain a modified ground speed signal having a characteristic which corresponds to the values of at least two of the liquid spraying parameters required to obtain the desired density.          A difference amplifier is responsive to the liquid pressure signal and the modified ground speed signal for generating a corresponding valve control signal.  A control valve is operatively coupled to the nozzles and is responsive to the valve control signal for adjusting the rate of flow of the liquid to the nozzles to maintain the pressure of the liquid at the nozzles at a level which corresponds to the selected values of the liquid spraying parameters to thus spray the liquid at the desired density.                             -1a-

Abstract: ABSTRACT OF THE DISCLOSURE            Abrupt transitions in the televised scene between areas of low and high brightness can occasion horizontal sweep system loading to produce raster distortion. Scan compensation circuitry which utilizes the loading of the horizontal sweep system as an input corrects raster position distortion, raster width dis-tortion and raster tearing distortion.  Position distortion is corrected by delay of the start of horizontal retrace in order to shift the start of trace.  Control of horizontal yoke drive to maintain appropriated yoke drive to CRT anode voltage ration corrects width distortion.  Raster tearing is prevented by limiting the drive to the picture tube when sweep system loading would exceed a predetermined threshold.

Abstract: IMPROVED SKID CONTROL SYSTEM      Abstract of the Disclosure:  A skid control system is provided for use with a vehicle having a pair of spaced apart wheels and having a braking system for applying braking forces to the wheels.  A brake control circuit responds to a skid signal obtained from any one of a plurality of in-cipient detector circuits to act upon the braking system to release the braking forces.  A delayed skid signal is provided whenever the difference in wheel speeds of the two wheels exceeds a given amount.  A delayed skid signal is also provided if the average wheel speed of the two wheels de-creases at a rate greater than a desired decreasing rate. If both wheels decelerate, a skid signal is provided upon sensing that the faster wheel is decelerating at a rate greater than a reference rate.  As the wheels spin-up toward an ideal velocity for a braked vehicle, an accelera-tion detector serves to insure wheel roll up on low friction surfaces.  If the wheels spin up at an acceleration greater than an acceleration level, the acceleration detector output is inhibited.  If the acceleration is less than the preceed-ing level and more than a second level, a skid signal is provided.  Also, as the wheels spin-up to a desired velocity, braking forces are restored when the rate of acceleration declines below the second acceleration level.  Monitoring circuits are provided for monitoring various operations of the skid control system and deactivate same when the operation is not within prescribed limits.

Abstract: Abstract of the Disclosure A tiltable discharge valve for pressurized containers is suitable for dispensing a high viscosity product, at an unexpectedly low pressure. The valve provides for increasing flow-through cross-sectional area, as the container pressure falls, and includes a large disc or head secured to a tiltable stem.  The container pressure presses the disc into the valve seat and the valve disc tilts around its fulcruming ring to raise its sealing ring off the valve seat.  The valve seat is quite yieldable and the sealing ring sinks in deeper into the seat under higher container pressure and sinks less deeply into the seat as the container pressure decreases, whereby the extent the sealing ring rises off the seat upon tilting of the stem is container pressure determined, and the amount of product delivered to the stem outlets remains generally constant even as container pressure decreases.
