Abstract: ABSTRACT OF THE INVENTION   A sensor array provides a plurality of distinguishable bitmap images and comprises an array of sensor cells capable of sensing radiation. The cells are connected in a manner to form distinguishable bitmap images through a pattern of correspondence among the cells. Each bitmap image formed comprises a combination of one or more cells indicative of detecting a irnage pixel within a field of array cells that have been nonindicative of such detection. The pattern of correspondence may be one of inhibition of the operation of other cells in the array or one of indication of operation to other cells in the array. Various patterns of correspondence can be created among the cells creative of bitmap images. Bitmap images may consist of combinations of responsive cells within a field of nonresponsive cells in the array. For example, each bitmap image may comprise radiation responsive array cells that have sensed a sufficient quantity of radiation within a field of cells which have not sensed radiation or have been inhibited from sensing radiation. On the other hand, each bitmap image may comprise array cells that have not sensed a sufficient quantity of radiation within a field of cells that have sensed a sufficient quantity of radiation. An application of the sensor array is in an IC chip for a curser control device or an optical mouse" for use with an interactive display orientedcomputer system to provide movement for a visible cursor from position to position on a display screen of such a system.

Abstract: ABSTRACT OF THE DISCLOSURE           A float valve mechanism for a cistern or tank comprising a housing defining a closed chamber having an inlet port connected to an inlet pipe to the cistern or tank, an outlet port from the chamber having a valve seat surrounding the port.  A valve member passes through the opening and has a valve head located within the chamber, the valve head being integrally formed, preferably from a plastic material, with a lever which is pivotal about axis and carries a float.  The valve head is pivotally movable in an integral manner with the lever along a path passing through the outlet port of the chamber.  Water pressure within the chamber normally urges the valve to the closed position and the weight of the float when the water has fallen below a given level in the tank overcomes this pressure to allow water to flow from the chamber into the cistern.

Abstract: Abstract of the Disclosure A process for regenerating a resin, comprises the steps of dissolving a waste resin in an organic solvent to provide a resin solution, mixing the resin solution with a liquid of normal temperature, the liquid being immiscible with the solvent, scarcely dissolving the resin, and having a specific gravity smaller than that of the solvent and larger than that of the resin, thereby separating the resin from a mixture of the resin solution and the liquid, and recovering the resin.  The liquid may have a temperature higher than the boiling point of the solvent.  In this case, the solvent evapo-ration takes place together with the resin separation.          The evaporated solvent is cooled later for recovery of the solvent.

Abstract: AUTO TUNING FOR AN OSCILLATOR              ABSTRACT OF THE DISCLOSURE           To adjust the free running frequency of a voltage controlled oscillator so that it is close enough to a target frequency for a phase locked loop to lock the frequency, a reference signal is derived from a stable external source.  A derived signal is generated from the oscillator.  The derived signal and the reference signal are applied to a comparison circuit which examines the relationship of a specific edge of the reference signal at times determined by the signal derived from the oscillator.  If the oscillator is within its proper frequency range, the edge of the reference signal will have a certain relationship to the times determined by the derived signal.  If this relation-ship is found to be improper, correction signals are applied to the oscillator.  In the preferred embodiment, this occurs in a television receiver where the reference signal is based on a 3,58 megahertz signal.  The examination which is made takes an output from a counter which divides by 455, specifically, the 160 count.  Times T1 and T2 are developed based on the output of the oscillator,  At time T1, the counter output should be low, but at time T2, the counter output should be high. Approximately a 1 microsecond tolerance is provided in both directions,  Error is permitted to accumulate during a part of the vertical retrace time.  If the error becomes too great, corrective action is taken.

Abstract: BICOMPONENT FIBERS AND WEBS MADE THEREFROM        Abstract Bicomponent fibers, and webs made therefrom, are taught in which one component of the fibers is a crystallizable material.  When a web of the fibers is heated in a mold above the temperature at which crystallization occurs, the fibers tend to be set in the position they are held in the mold.  A preferred fiber comprises blown fibers comprising as one component amorphous, crystallizable polyethylene terephthalate, and as the other component polypropylene.  A web of such fibers not only becomes formed into a shape-retaining form by crystallization during the molding process, but also can be further established in its shape-retaining character by heating the web above the softening point of the polypropylene, whereupon the fibers become bonded at their points of intersection.

Abstract: Abstract of the Disclosure An uninterruptable power supply and line con-ditioner of the class using a local battery and the util-ity power lines as the sources of power for an AC load, and in which a pulse width modulation (PWM) inverter is used to convert the battery DC to the load AC and to charge the battery from the power lines.  The utility power lines are effectively connected to the load by way of a series inductance, and the phase angle between the inverter out-put voltage and the effective input voltage to the induc-tance from the power lines controls the proportioning of current to the load and to the battery from the power lines, and from the inverter to the load.  The necessary inverter current is reduced and the throughput efficiency improved by, in effect, providing a predetermined ratio R between the voltage applied to the input side of the inductor and the voltage at the inverter output; in a preferred embodiment the effective input voltage is about 1.1 times the inverter voltage, and is produced by use of magnetic shunts in a transformer which couples the utility line to the load.
