Abstract: Abstract The stereophonic sound synthesizer utilizes a phase splitter in the form of a transformer (20) to develop two oppositely phased audio signals, (A,B) from an applied monaural signal (M).  One (A) of the two oppositely phased signals is applied to a transfer function circuit (30,40,50) of the form H(s), which modulates the intensity of a monaural signal as a function of the frequency.  The intensity modulated H(s) signal may be applied to via an output (92) an amplifier for subsequent amplification and reproduction.  The H(s) signal is also combined in a passive combining circuit (72, 74) with the other (B) of the two oppositely phase signals to produce at an output (94) a difference signal H(s) + M' which is the complement of the H(s) signal.  The difference signal may be applied to an amplifier for subsequent amplification and reproduction.  No differential amplifier is necessary to producer the difference signal because the necessary selective phase opposition of the signals combined in that transformer output signals.  The synthesizer is especially applicable for use in a television receiver in which the transformer (20) electrically isolates the television's electrical system from the stereo synthesizer system's signal outputs, which may thus be applied to an external stereo amplifier safely.

Abstract: ABSTRACT     A switch assembly adapted for actuation by connection to an engine throttle shaft.  The switch housing is adapted for mounting on an engine and has a rotary cam received therein having a socket for connection to the engine throttle shaft.  Rotation of the cam sequentially actuates a plurality of electrical switches.  The housing has a stationary and movable member with some of the switches mounted on each.  A helical screw engages teeth on the movable member and for adjusting the relative position between the housing members.  The screw is readily accessible from the exterior of the housing and rotation of the screw adjusts the at-rest position of the cam with respect to the switches for enabling easy calibration after installation on the engine.

Abstract: Abstract Compressed-air pile-driver The invention relates to a compressed-air pile-driver, especially for axially insertable tools, which consists of a ram 20 located in a housing 8.     The housing interior is divided by the ram 20 respectively into an upper compression or expansion chamber 21 and a lower compression or expansion chamber 22 which can each be connected alternately to a compressed-air source via air connection pipes 19, 30 and a control valve 83 and which each have an air-outlet-orifice 27 opened alter-nately by the ram 20.     In the upper expansion chamber 21, a pressure chamber 18, into which the upper air connection pipe 19 opens, is divided off by an intermed-iate plate 5 approximately parallel to the end face 80 of the ram 20.     Located in the intermediate plate 5 is at least one orifice 38 which connects the pressure cham-ber 18 to the expansion chamber 21 and which is closed in a leak-proof manner by the ram 20 in its upper dead-center position, the ram 20 additionally being retained firmly in its upper dead-center position by a retaining device.     Only when a pressure overcoming the retaining force of the retaining device is built up in the air-inlet orifice 38 is the ram 20 thrown explosively downwards, absorbing high energy in the course of short acceleration paths.     The housing 8 of the compressed-air pile-driver is injection-moulded from plastic, preferably polycarbonate, in order to save weight and cost.

Abstract: REAL TIME DIGITAL SCAN CONVERTOR Abstract of the Disclosure A digital scan converter is disclosed wherein signal information supplied by a sector scanning surveillance system relative to a polar coordinatesystem is converted to a signal for driving a television-type display or other Cartesian coordinate device by: (a) sampling the signal associated with each consecutive scanning path of the surveillance system at a rate determined by theazimuthal angle that defines the scanning path of interest; (b) storing each set of signal samples as a column of data in a rectangular memory array; (c) accessing the stored data on a row-by-row basis; and (d) utilizing a previously determinedmapping strategy to cause each accessed signal sample to form a segment of a line of display within the Cartesian-formulated display devices so that the length of the segment formed by each signal sample is determined by the row and column address of the storage location that is associated therewith when forminga television compatible signal, each signal sample dictates video signal level during a portion of a corresponding horizontal sweep period that is determined by the mapping strategy.

Abstract: ABSTRACT OF THE DISCLOSURE         A steam turbine system which includes a steam generator  and  a  steam  bypass path for bypassing steam around the turbine.  The outlet throttle pressure of the steam generator is controlled by controlling admission of steam into the bypass path by means of a bypass valve.  A desired throttle pressure set point is generated which is independent of steam flow and this set point is compared with the actual throttle pressure for governing the bypass valve during turbine start-up.  When the turbine is fully operational  the bypass valve  control  is  effected by a comparison of the actual throttle pressure with the de-sired throttle pressure set point plus some bias.

Abstract: ABSTRACT:               An electron source having a rapid response time comprises at least on n-p-n structure (and possibly an array of said n-p-n structure) formed in a silicon or other semiconductor body (10) by a p-type first region (1) between n-type second and third regions ( 2 and 3).  Electrons (24) are generated in the n-p-n structure (2,1, 3) for emission into free space (20) from a surface area (4) of the body (10) after flowing from the second region (2) through the first and third regions (1 and 3).  The n-p-n structure (2, 1, 3) has electrode connections (12 and 13) only to the n-type second and third regions (2 and 3).  The first region (1) provides a barrier region restricting the flow of electrons from the second region (2) to the third region (3) until a sufficient potential difference is applied between the electrode connections (12 and 13) to bias the third region (3) positive with respect to the second region (2) and to establish a supply of hot electrons (24) injected into the third region (3) with sufficient energy to overcome the electron work function between the surface area (4) and free space (20). The barrier region (1) forms depletion layers with both the n-type second and third regions (2 and 3) and is depleted by the merging together of these depletion layers when the potential difference is applied to establish said supply of hot electrons (24).
