Abstract: MICROPROCESSOR SIGNAL DETECTOR                     Abstract A programmed processor is utilized for serial signal detection.  Signals generated by double frequency magnetic recording are received by logic which is controlled, and sensed, by a sequence of program instructions from a microprocessor. In particular, a technique is disclosed by which a special pattern of signals is to be recognized.  The special pattern of signals is known in the magnetic disc recording art as an address mark which is a unique pattern of interspersed clock signals and data signals.  The pattern is made more unique from any other pattern of data by the fact that certain of the clock signals are missing.  The ability to utilize a microprocessor, which is relatively slow, in a magnetic recording system in which the bit rate is relatively fast, is enhanced by a particular processor program instruction which is effective to access a next following instruction from program storage and then stop the clock of the processor.  The clock is re-started, and therefore execution of the next instruction initiated, upon receipt of a timing signal from the logic receiving the signals to be detected.

Abstract: OPTICAL SYSTEM FOR MULTIPLE IMAGING OF A LINEAR OBJECT          Abstract of the Disclosure An optical system for imaging a linear object, such as for a solid state imaging device as used in a facsimile printing apparatus, uses a multiplicity of mirrors to produce a similar number of images.  The mirrors are tilted and rotated relative to each other so as to produce the images side-by-side and also staggered longitudinally.  The mirrors need only be of a width to reflect part of the object, resulting in the imaging of different portions of the object by each mirror, the different portions imaged side-by-side on the imager array so that the whole object can be reconstituted from the various sections.  This enables a relatively short and wide imager array to be used instead of a long thin one.                             -i-

Abstract: Application of Richard P. Heintz Title:  Hybrid Propulsion System ABSTRACT OF THE DISCLOSURE         The hybrid propulsion system utilizes an internal combustion engine for driving a free-piston engine-pump unit, which pressurizes a working fluid, which in turn is used for driving a hydraulic motor.          The free piston engine pump has opposed power pistons and pumping pistons fixedly connected therewith.  Air is supplied to the combustion chambers of the power pistons from an intermediate air supply chamber associated with each of the power pistons.  High and low pressure accu-mulators for the working fluid are also connected via a conduit and valving system to the pumping chamber so that fluid is supplied from the low pressure accumulator to the pumping chambers, and is pressurized by the engine-pump unit and discharged to a high pressure side of the system, which includes the high pressure accumulator.  The cycling con-trol valve assembly is activated during startup of the engine-pump unit to drive the unit until self-sustained reciprocating movement of the unit can be achieved.

Abstract: IMPROVED WALLAWAY RECLINER CHAIR                      ABSTRACT OF DISCLOSURE         A recliner chair with "wallaway" action which permits the chair to be placed adjacent a wall without striking the wall when the chair, is moved to reclining positions.  The wallaway action is achieved through a linkage which suspends the seat and its rigidly incorporated armrests, relative to a fixed base for swinging move-ment between a normal or generally upright position, and a number of reclining positions where the backrest extends rearwardly at an incline and the seat also extends at an incline.  A handle-operated footrest is provided and an actuating and control link is connected between linkage which actuates the footrest and the linkage which mounts the seat to the base so as to move the latter forwardly rela-tive to the base when the footrest is moved to extended position to provide a certain amount of wallaway action.  This actuating and con-trol link prevents movement of the backrest relative to the seat when the chair is in normal position or is operated to extend the footrest.  However, once the footrest is in extended to "TV" posi-tion, the backrest may be pivoted rearwardly relative to the seat to provide advanced reclining positions by the occupant exerting back pressure on the backrest.  This also operates to swing the seat forwardly and upwardly relative to the base to provide further wall-away action and also to position the seat in a comfortable reclining position. The chair is maintained in any of its positions by virtue of the balance of the linkage system, and no spring assists are needed to help to maintain position or move the chair into any new position.

Abstract: ABSTRACT OF THE DISCLOSURE             The apparatus includes a fluid-tight housing oscillated about a vertical axis, the housing containing a central deflector separating the housing into an upper chamber and a lower chamber.  Baffles are provided in both chambers, above and below the deflector.  The upper baffle directs the incoming slurry radially outwardly in a torical path, throwing the particulate material toward the periphery of a housing in the first separation zone the particulate material passing in a gravity induced flow, through the annular passageway into the lower hopper where the relatively lighter and heavier constituents are then separated and separately discharged from the housing.  A ring dam formed in the second baffle provides a recess into which the lighter constituents overflow where they are reunited with the liquid flow path and thus discharged from the housing.  An aspirator removes air automatically from the top of the chamber.  The method carried out by the apparatus is claimed.  In a second embodiment the slurry is introduced tangential in the upper chamber and radial paddles or baffles arrest the whirlpool thus created, so that during the first portion of operation the slurry is subjected to centrifugal action and subsequently to settling action.  In other forms of the invention, recirculating closed systems are provided for re-circulating the fluid medium.  Also, the flow rates of the fluids and solids or particulates are independently adjustable by various means.  The slurry is formed from fluid particulate material. Either gas (air) or liquid (water) is used as the fluid medium and finely divided solids such as gold ore is used as the particulate material.
