Abstract: ABSTRACT OF THE DISCLOSURE :           For the generation of inverse time characteristics for time-lag type over-current relays or the like, by approxi-mation of the time function by means of individual, linear parts into a time function which is discontinuous at a number of break points, there is provided an integrated circuit fed by an ope-ration amplifier.  A plurality of amplifier circuits correspon-ding to the number of break points in the approximated time function each has at least one input and at least one output and operates as an ideal diode.  The input of each of the am-plifier circuits is connected to an input voltage source.  An arrangement is provided for selectively connecting the output of each of the amplifier circuits to the input or output of the operation amplifier, depending on whether the linear part of the time function, determined by a selected amplifier circuit, has a greater or smaller derivative than the preceding linear part of the time function.

Abstract: ABSTRACT OF THE DISCLOSURE         In a system for measuring the time delay existing between two pattern related random signals of similar but not identical modulated characteristic, utilizing the techniques of cross correlation, two analogue input signals are digitally quantized into binary form according to signal polarity. The first or leading quantized signal is delayed by a series of sequential time intervals or sampling periods to provide a time controlled sequence of delayed leading-signals at equal intervals.  These delayed leading-signals are compared by a multiplication technique with the quantized second or lagging-signal, the occurrence when the signals correspond being summed in a series of overflow counters.  The rate of filling of the respective counters is proportional to the respective degree of correspondence and leads to one counter overflowing first, being indicative of the most probable time delay between the two signals.  A variable frequency oscillator is used to control the sampling period so that overflow takes place most often in a selected one of the series of counters.  To improve the time delay resolution, and to utilize higher frequency components of the signals, once a definite indication of cross correlation is achieved, the sampling period is reduced to a chosen fraction, such as one fifth, and increasing the number of time delay intervals imposed on the leading signal by the corresponding integral multiple, namely five to maintain the overflow in the same selected counter.  The two mode operation described permits enhanced precision of time delay determination with economy of components.  The readout for the system is derived from the oscillator frequency.  The system is suitable for use with an ultrasonic velocity meter for measuring  liquid flow in a pipe.

Abstract: ABSTRACT OF THE DISCLOSURE An all-channel two mode television tuning system includes a presettable counter for deriving the number of a receivable television channel by counting the local oscillator frequency.  The frequency is varied by a ramp voltage circuit under the control of a comparator which adjusts the tuning based upon the difference between the derived channel number and a desired channel number sequentially generated by externally activated counters.  A 82 x 1 bit read/write memory is addressed in the first or program mode by the generated channel number to provide locations for storage of signals for tuning to preselected channels.  In the second or operate mode logic circuitry interrupts the advancement of the channel counters whenever a generated channel number corresponds to a preselected channel number.

Abstract: ABSTRACT      An archery bow accessory having a hand grip with a bow string holding and releasing mechanism, a draw tube projecting from the hand grip, and a guide connected with the bow and receiving the draw tube.  The guide has a lock for retaining the draw tube in a bow flexed position.  By drawing back on the hand grip the bow can be flexed and if desired retained in such condition by the lock means on the draw tube and guide until an arrow is to be projected.  This function can be performed by depressing a plunger with thumb pressure to release the bow string and arrow from the handle.  A simple twist of the handle will release the draw tube from the lock on the guide to permit the hand grip to be moved toward the bow for repeating the bow flex-ing operation.  If the bow is to be unflexed without discharging the arrow, the hand grip may be slightly twisted to release the draw tube from the lock in the guide and the bow string moved toward the bow under the control of the operator.

Abstract: ABSTRACT OF THE DISCLOSURE        A system for using a video signal recorder/playback device of the type normally adapted to record and/or reproduce video signals on a record medium, for recording and/or reproduc-ing pulse signals on the record medium. The system includes time-compression/time-expansion apparatus for compressing the time domain of the pulse signals which are to be recorded and for expanding the time domain of the pulse signals which are reproduced. The time-compression/time-expansion apparatus includes a memory having addressable storage locations for temporarily storing pulse signals therein; write-in circuitry for writing pulse signals into the addressable storage locations pulse signals at a second rate, the write-in and read-out cir-cuitry operating substantially independently of each other and at the same time; and an address generator for generating selected write-in and read-out addresses corresponding to the storage loca-tions into which the pulse signals are written and from which the pulse signals are read. The apparatus also includes a detector for selectively detecting when all of the storage locations are filled or are empty, in which the detector includes an address compactor for comparing each bit in the write-in address code to each corresponding bit in the read-out address code to detect when all of the compound bits represent the same storage location. For time-compression, the read-out rate is faster than the write-in rate. For time-expansion, the read-out rate is slower than the write-in rate. The apparatus further includes a pulse generator coupled to the address comparator for generating a reset pulse when the address codes generated by the write-in and read-out address generators are equal.
