Title: Improvements in and relating to stercophonic radio signal receivers
IPC: H03D1/22
Filed: 1965-01-04
Abstract: 1,074,071. Stereophonic radio signal receivers. PHILCO-FORD CORPORATION. Jan. 4, 1965 [Jan. 3, 1964], No. 229/65. Heading H4L. In a radio receiver for monophonic signals or for use with the standard U.S.A. stereophonic broadcasting system, comprising a switching or sampling type of stereo decoder, means are provided for deriving a crosstalk correction signal from the composite stereophonic signal and for applying the correction signal to the input of the sampling circuit. As shown in Fig. 2, the composite signal from the F.M. detector 11a is supplied at 15a to the decoder circuit comprising diodes 19a to 21a and the 19 kc/s. pilot signal is supplied via tuned amplifiers 43, 45 and frequency-doubler 47 including the primary of transformer 18a tuned to 38 kc/s., as a switching signal to the decoder circuit. The transistor 47 operates as a Class C amplifier so that with no signal input the emitter current is zero, a neon lamp 54 indicating stereophonic reception. Negative feedback between the emitters of transistors 45, 47 provides automatic amplitude control. During stereophonic reception a direct voltage is developed across resistor 52 rendering diode 50 conductive so that a portion of the composite signal, as determined by potentiometer 49, is supplied to the centre-tap of the secondary winding of transformer 18a to correct for crosstalk. Capacitors 41, 42 correct phase errors in the derived stereophonic signals which appear at L and R respectively, and capacitors 33a, 34a provide de-emphasis. During monophonic reception there is no voltage across resistor 52 and diode 50 is non-conductive.

Title: Multiple channel trace recorder with trace indentification
IPC: G01D1/00
Filed: 1973-01-03
Abstract: 1415911 Cathode-ray tube displays HONEYWELL Inc 3 Jan 1973 [3 Jan 1972] 322/73 Heading H4T [Also in Division G1] A multiple channel trace recorder produces a plurality of traces 4 (Fig. 1) on a record medium 2, a series of channel numbers 1, 2, 3 ... 10 along one margin thereof and an indicator line 6 extending from each number of the corresponding trace. The invention is described in connection with a recorder employing a cathoderay tube but is stated to be applicable to recorders such as those which record by selective energization of pins in a row transverse to the record medium or those using a mirror galvanometer. As shown in Fig. 2, the traces appertaining to respective ones of m input channels 16 are produced, in known manner, by comparing the channel input data in comparators 20 with the output of a sawtooth wave generator 10, the comparators supplying an output when the magnitude of the sawtooth equals that of the input data such output being fed directly to one input and via delay lines 24 to the other input of exclusive-OR (XOR) gates 22 which produce "connected" samples for unblanking via OR gate 26 and amplifier 14, the beam of a cathoderay display tube 8 as it is scanned in a repetitive single line scan by the sawtooth from generator 10. This scan is transverse to a moving record member 2 on which a printing assembly 28 prints the channel numbers and as the assembly 28 is actuated to index it to the next number as the record member 2 moves vertically, a signal generator 30 is energized to produce a pulse of duration equal to that of the sawtooth from generator 10. This pulse is applied to a divider counter 32 and also conditions an AND gate 34 which passes a trigger signal, derived via inverter 38 and differentiator 40 from the retrace portion of the sawtooth, to " set " a bi-stable flip-flop 42 the Q output of which, via OR gate 26, unblanks the beam at a position adjacent the channel number which has just been printed so that the beam commences to trace an indicator line. Divider counter 32 produces a number output corresponding to the appertaining channel number and this number which may be in any convenient code configuration is decoded in 46 to produce an output indicative of the particular channel which output conditions AND gates 50 such that when the particular channel data is supplied by the appropriate gate 22, the appropriate gate 50 passes a signal via OR gate 52 which resets flip-flop 42 and removes the unblanking signal. Thus the indicator lines starts from a channel member and terminates at the trace corresponding to that channel. Means may be provided for suppressing channel indicator lines corresponding to unused traces and instead of employing the printing assembly 28 the channel numbers may be produced by supplying suitable signals to the tube.

Abstract: 100,818. Westinghouse Brake Co., (Assignees of Turner, W. V.). July 13, 1915, [Convention date]. Addition to 8375/15. Fluid-pressure.-In a device of the hind described in the parent Specification for restricting the discharge of air from the train-pipe at the driver's valve so as to obtain a more uniform reduction of pressure and application of the brakes throughout the length of a long train, the restriction is effected by a piston valve 16 separate from the equalizing-piston 7, leakage around which is thus prevented from affecting the proper operation of the device. The valve 16 working in the fixed bushing 22<1> is open above by passages 8<1> and 23. 4 to the equalizing-reservoir 5 and equalizing-valve chamber 8, and below at the central part to the train-pipe 6 by passage 14. The remainder of the lower face of the valve 16 is exposed to equalizing- reservoir pressure when the valve is seated in the lower position shown, by ports 27, 29 and passage 28. The train-pipe further communicates with the equalizing-valve chamber 9 by ports 11, 12 in the bushing 22<1> and annular passage 13 in the valve 16. If, in making an application of the brakes, the pressure reduces faster in the equalizing-reservoir than in the train-pipe, the valve 16 is forced upwardly when a sufficient differential pressure has been established, so as to cover the ports 12, leaving open only the ports 11. When the driver's valve is moved to lap position, the valve 16 again falls, and final exhaust from the train-pipe takes place at the initial rate.

Title: Motor control systems
IPC: H02P5/69
Filed: 1966-01-06
Abstract: 1,134,054. Automatic control of speed. BROOKHIRST IGRANIC Ltd. Jan.6, 1966 Jan.6, 1965], No.626/66. Heading G3R. [Also in Division H2] A system for controlling the speed of a printing press with load sharing between its plurality of D.C. driving motors comprises means for comparing the output of a single tachogenerator with a speed reference signal, the resultant error signal between supplied to each motor control unit as a current reference with which the respective armature current is compared. Comparison is made in magnetic amplifiers MFC (one only) and MX (one for each motor) which are stabilized by a feedback loop which for MFC is adjustable to vary the gain. Current limiting is provided by the saturation point of MFC. The speed error/motor current characteristic, and the actual current limit, may be modified by supplying a speed reference signal to an additional winding on the amplifiers MX via a rheostat or function generator CTSG. The speed reference signal is produced by a potentiometer driven by a push button controlled pilot motor for automatic acceleration. For inching a separate reference voltage and winding on MFC is provided. The motor armatures are energized from a three phase supply via thyristor bridge power circuits, with separate firing circuits controlled by amplifiers MX; the shunt fields are energized via normal rectifiers. Dynamic braking into a resistor is provided, during which the field is weakened until the armature voltage drops to a given value. A solenoid operated brake is controlled by the pilot motor. Operation is controlled by a push button and relay system which is fully described, and provides for inching, threading, running, normal stop and emergency stop due to power failure or web breakage. For emergency stop, dynamic braking is automatically applied after a timed interval and for all stops the internal feedback of amplifiers MX is increased to switch off the power. Various safety measures are incorporated, including the sounding of an audible warning when the press is set to "ready", and automatic reversion to "safe" if no motion buttons are pressed within three seconds. Two stages of testing are provided, one for the control circuits only, the other up to and including the power circuits, which are then connected to resistors, with the motor armatures open circuited. All the motors are coupled via clutches, and an individual one may be operated alone; in this case the tachogenerator signal will be absent, and the appropriate amplifier MX has an armature voltage feedback signal applied to a special winding.
