Abstract: ABSTRACT OF THE DISCLOSURE       This invention relates to a novel process for producing polymer/polyols characterized by the use of specific combinations of acrylonitrile and styrene and by utilizing certain peroxyester catalysts.  Methacrylonitrile and/or alpha-methyl styrene may optionally be used as substitutes for the acrylonitrile and styrene, respectively,  The process produces novel polymer/polyols characterized by relatively high polymer contents and increased stability.  These polymer/ polyols are stable, fluid, essentially free from scrap and seeds as produced and contain relatively small polymer particles such that, in the preferred embodiment, essentially all are less than about 30 microns in diameter.  The novel polymer/polyols are useful in producing polyurethane foams of reduced scorch and improved load bearing properties and polyurethane elastomers having improved stiffness properties.

Abstract: ABSTRACT OF THE DISCLOSURE      A frequency spectrum analyzer adapted for use in a real time signal processing radar system is disclosed.  In such system a plurality of sets of radar returns, each one of such sets corresponding to radar returns from objects disposed in each one of a like plurality of range cells, is stored in a time compressor section, the radar returns in each one of the sets thereof being stored at the pulse repetition frequency (PFR) of such radar system.  After storage of such radar returns, a like plurality of chirp pulses is produced, each one of such pulses having a dispersive time K?. Synchronously with each one of the chirp pulses, one of the plurality of sets of stored radar returns is retrieved from the time compressor section, in of chirp pulses to produce a series of mixed signals which is coupled to a pulse compressor.  Each one of the mixed signals is compressed into a pulse occurring at a time related to the Doppler frequency of any object in the range cell producing such associated radar returns.  The time compressor section is used prior to pulse compression to effectively "match" the radar dwell time, generally several milliseconds in duration, to the dispersive time of the chirp pulse, generally several micro-seconds in duration, thereby enabling the pulse compressor to include a practical surface acoustic wave (SAN) delay line.

Abstract: ABSTRACT OF THE DISCLOSURE       This is a device for forming vents or bores in con-crete floors.  A cylindrical base portion is secured to the surface upon which the concrete is to be poured and a rigid foam cylindrical portion is pushed downwardly into the base whereupon an upper cylindrical guard portion may be pushed over the upper end of the cylindrical core.  Both the base and the-guard portion are provided with inwardly projecting lugs which hold the cylindrical core into the base and hold the guard portion of the upper end of the cylindrical core.          An ignitor cord harness extends around the cylindrical core which, when ignited, melts this core.  The concrete floor is poured with the guard portion projecting above the floor level and after the concrete has set, the ignitor harness can be ignited thus melting and charring the core thus leaving a smooth cylindrical bore through the concrete floor.

Abstract: DIGITAL PRESSURE STANDARD          Abstract of the Disclosure Pressure regulator system and apparatus for producing a controlled output pressure corresponding to a pre-programmed BCD set point command. Measured values of output fluid pressure emitted from the regulator is applied in BCD signal form to electronic logic in which the measured signal is compared with the signal of the set point.  In response to a determined differ-ential between signals, output pressure is changed in a series of repetitive but rate variable differential reduction steps until set point pressure is achieved.  In each step a D. C. motor under control of a logic actuated servo-system operates a force balanced air system to adjust a primary control pressure which in turn operatively resets the output pressure of the regulator.

Abstract: ABSTRACT OF THE DISCLOSURE      A semiconductor amplification device which can be fabricated as a monolithic semiconductor structure is provided for use in an automatic gray scale control circuit for a color television receiver.  During the blanking inter-val, the control circuit senses the cut-off voltage of each gun of a three gun color cathode ray tube and stores that voltage.  During the video field, the stored voltage is used to energize the driver for the individual gun and to bias that gun.  The automatic gray scale function for each gun requires two amplifiers of high current gain, high inverse impedance, only one of which is on at a time, and a consolidation of the sensing and output functions in two terminals.  These functions are achieved in a four transistor configuration in which two cascaded pairs of emitter folloer transistor am-plifiers are connected in a closed loop.  A high inverse impedance is achieved by the provision of a second emitter in the output transistor of each cascaded pair, coupled to the base of the preceding transistor to insure turn off.

Abstract: ABSTRACT OF THE INVENTION          A data transmission system using analog to pulse width to digital conversion for transmitting data generated by an analog sensor to a digital processor is disclosed. A data request signal generated by the digital processor is gated by a processor interface circuit along a single wire data transmission line to a remote sensor activating both the sensor and its associated interface electronics. The data request signal also provides electrical power to the sensor and sensor interface electronics eliminating the need for separate electrical power leads. The sensor interface electronics after a period of time determined by the value of the analog signal generated by the sensor generates a low impedance to ground signal on the data transmission line. The low impedance to ground signal is detected by the processor interface circuit which terminates the transmission of the data request signal. The processor interface circuit further includes a pulse width to digital converter generating digital data indicative of the duration the data request signal is transmitted. More than one sensor may interface the single data transmission line and each sensor interface may be individually activated by interrogation signals generated by the digital processor.
