Abstract: 769.002 S P E C I F I C A T I O N        VARIABLE VOLTAGE DIRECT CURRENT POWER SUPPLY                 AND MOTOR SPEED CONTROL     INVENTOR:  STANLEY G. PESCHEL                 ABSTRACT OF THE DISCLOSURE         A continuously variable voltage direct current power supply is provided using a variable transformer with a core of magnetically permeable material which is encircled by at least one electrical winding, with segments of the turns of the winding being exposed along two spaced traverse paths for electrical contact by movable brushes.  First and second electrically conductive brushes are sumultaneously movable along the respective traverse paths of the winding, with at least one of the brushes at all times contacting an exposed segment of the winding.  First and second bridge rectifier circuits couple the first and second brushes to the same DC electrical load.  The first and second bridge rectifier cir-cuits are coupled in parallel between the respective brushes and load circuit.  Turn-to-turn short-circuit AC current be-tween the adjoining turns contacted by the brushes is eliminated by employing a transformer winding having a turn-to-turn voltage which is less than the forward turn-on voltage through two or more rectifiers (unidirectional conduction devices).  Turn-to-turn current can only flow from one brush to the other through at least two rectifiers plus the resistance or impedance of the electrical load. Where it is de-sirable to utilize higher turn-to-turn voltages, more than one rectifier can be connected in series in each branch of the rectifier circuits.  In those cases where the DC load can function with a relatively minor component (approximately one percent or so)of superimposed AC current, then irrespective of the turn-to-turn voltage and the number of rectifiers in series, the turn-to-turn current circulating from one brush to the other through the load is held to an insignificant value by the load resistance or impedance itself.  The variable transformer which is utilized may include both primary and secondary windings or an autotransformer may be utilized.  Single-phase or multi-phase variable transformers can be used in this DC power supply, and advantageous DC power control can be effectuated on a considerably more economic basis than heretofore, for example, to control the speed of large (multiple Horse Power) DC motors.

Abstract: Abstract of the Disclosure In the recording operation of a video recorder, a color signal (3.58 MHz) is frequency-converted to a low frequency converted color signal (688 kHz) by a color signal processing device.  In the reproducing operation of the video tape recorder, the regenerative low fre-quency converted color signal (688 kHz) is reconverted to the color signal of original frequency (3.58 MHz) by the color signal processing device.  The signal (3.58 MHz or 688 kHz) which has passed a switching circuit is gain-controlled by a color signal amplifier and is input to a balanced modulator.  A converting signal (F03 = 4.27 MHz) is also input to the balanced modulator.          The output of the balanced modulator is obtained as a frequency-converted signal (688 kHz or 3.58 MHz) through a low-pass filter or a band-pass filter.  The converting signal (F03 = 4.27 MHz) is obtained by balanced modulation, at a second balanced modulator, of an oscillation output (3.58 MHz) of a first voltage controlled oscillator and a divided output (fO2 = 688 kHz) of a divider for dividing the output of a second voltage controlled oscillator.

Abstract: ABSTRACT OF THE DISCLOSURE         Every pressure vessel is connected by the agency of a connection channel to a control chamber. In both con-nection channels a shut-off valve is provided. The control chamber comprises a spring bellows  whereby a spring counteracts a pressure force acting onto the mean  area of said spring bellows. A ring is arranged on a control rod which controls the position of said shut-off valves. Upon a pressure loss in one of the pressure vessels the control rod operates the shut-off valves into their shut-off position such that upon a later pressure rise in one of the pressure vessels these shut-off valves remain closed.          This ensures that upon a later pressure rise in an undamaged of the two pressure vessels such will remain separated from the damaged one. This pressure control means is preferably used in a motor vehicle having twin tires such as a truck or bus.

Abstract: ABSTRACT OF THE DISCLOSURE            A novel fish lure is provided herein,  The lure is shaped in the form of a tail-less minnow having a main body of generally hydrodynamic shape including a head portion and a tail tip portion, the main body having, in side elevational view, a gently rounded upper back surface and an arcuately, oppositely, rounded lower belly surface and having, in top plan view, side faces which diverge from the head portion to a maximum body thickness and then converge to the tail tip portion.  A projecting, flat plate-like nose extends from the head in the form of a smooth continuous extension of the gently rounded upper back surface and extends downwardly less than the height of the body from the upper surface to the surface, the nose having a shape, in top plan view of forwardly diverging side faces, which terminate in a transverse, connecting bevelled edge, to provide two downwardly sloping side nose surfaces, the nose being provided with a plurality of spaced apart holes therethrough, disposed along the central longitudinal central axis thereof for securing a fish line drawn through a selected such hole.  A depending fin extends along the central longitudinal axis of the body, the tail fin being provided with a fish-line-guiding channel extending along an arcuate path longitudinally through it and along the body.  A fish line is adapted to be threaded through one of the holes. One hole imparts the most erratic action.  A second hole imparts lessened erratic action, and the third hole imparts extremely vibrant but tight movement from the center.  In all cases, the action of the plug is side-to-side at the same time as the plug oscillates on its longitudinal axis.  The fish lure is one to which can be imparted erratic action in which the ac-tion is a simultaneous side-to-side and oscillation on its longitudinal axis.  The lure may be patterned to represent a minnow more closely.

Abstract: ABSTRACT Disclosed is a microprocessor-based torque measuring system for a twin engine-aircraft gas turbine engine installation comprising respective induc-tive sensors, one for each engine.  The sensors are positioned to cooperate with respective pairs of toothed wheels, which are secured to axially spaced points on the engine shaft whose torque is to be sensed and have interlaced teeth whose spacing circumferential of the wheels varies with torque.  Each sensor produces a torque signal which, after suitable shaping, has a mark-space ratio representative of torque, and the respective durations of the mark and space periods of the signal are measured digitally by counting clock pulses during successive groups of mark periods and space periods.  The accumulated counts are then subjected to recursive digital filtering by the microprocessor, in accordance with a predetermined function approximating the response of a second order Butterworth filter.  The microprocessor then calculations the torque for each engine, using the appropriate filtered counts together with digital signals respectively representative of the temperature, stiffness and zero-torque twist of the respective shaft.
