Title: Communication system
IPC: H04B1/7136
Filed: 1963-06-19
Abstract: 1,129,882. Radio signalling. RAYTHEON CO. 19 June, 1963 [28 June, 1962], No. 24489/63. Heading H4L. In a coded radio transmission and receiving system, each digit of information transmitted (numerals or alphabetic elements), is represented by a unique frequency spectrum. A fixed number of separate frequencies are generated at the transmitter and all of these are transmitted in a separate sequence for each information digit, with a separation of 200 cycles per second. The transmitted signal consists of a series of separate frequencies occurring in sequence during a specified time interval. The digit pulse is thus expanded, giving increased power and range. At the receiver, the series of frequencies, representing each digit is subjected to a delay so that the frequencies appear simultaneously at the delay output terminals and are applied on code selector which selects the coded information in conjunction with a summing device to provide an output signal in the form of a time compressed pulse from the particular output line corresponding to received frequency signal, i.e. to the transmitted digit. The digits to be transmitted are introduced by the teletypewriter 12, Fig. 1a, through the code selector 16. The latter selects the appropriate frequency spectrum from the filters 30, by means of the gates 47 and the succession is formed by the summing circuit 34. The transmitter output comprises concentric frequency steps separated by multiples of 200 cycles/sec., ranging from 100 kc. to 109À4 kc. At the receiver, Fig. 1b, the received pattern of frequencies pass into the delay line 54 and appear simultaneously at the output lines. The particular code is selected at 56, which has selector cards corresponding to ten like cases in the selector 16. The component output frequencies are supplied to the correct filters of the matrix 58 and the output of the summer circuit is a composite pulse.

Title: Dynamoelectric machine control system
IPC: H02P9/04
Filed: 1953-09-08
Abstract: 745,695. Automatic control systems for motoralternators. BENDIX AVIATION CORPORATION. Sept. 8, 1953 [Sept. 26, 1952], No. 24836/53. Class 38 (4). A D.C. motor 5 energized from a battery 1 drives an alternator 15 producing an A.C. output between line 83 and earth. Networks 79, 80 and 70, 71 connected to the alternator output are resonant above and below the desired alternator frequency so that frequency deviations are automatically corrected by the consequent alteration in the relative energization of opposed windings 55 and 56 of a carbon carbon pile regulator 10 in series with a shunt field winding 7 of motor 5. Deviations of alternator voltage from a desired value influence a winding 31 of a carbon pile regulator 23 in series with field winding 14 of alternator 15 to effect automatic voltage correction. Winding 54 constitutes the main winding of carbon pile regulator 10 and compensation for variations in the load on alternator 15 is provided by an opposing winding 21 through which the alternator field current passes. Compensation of the voltage regulator for variations in frequency is provided by a winding 39 energized through a saturable reactor 45 from the alternator output. An opposing winding 40 eliminates the effect of temperature variations on winding 39. During the starting period when motor current is high, the volt-drop across a motor series field 8 is sufficient to operate a relay 27 which temporarily disengages automatic frequency control and opens the alternator field circuit.

Title: Improvements in means for the mechanical removal of dung
IPC: A01K1/01
Filed: 1944-12-11
Abstract: 583,603. Control of motors. BERGMAN, L. G. Dec. 11, 1944, No. 24842. [Class 38 (iii)] [Also in Group XXX] Dung is removed from a gutter 1, Fig. 1, in a stable floor by a reciprocating scraper 2, the length of travel of which is increased gradually. The scraper is driven by an endless rope 12 actuated by a motor 13. The motor 13 drives a threaded shaft 18, Fig. 4, on which is mounted a nut 19 carrying pivotally an arm 20. One end of this arm is linked to a pole-changing switch 21 connected with the motor. The other end of this arm moves over a series of liftable stops 27 mounted on a shaft 26 which are raised in succession by projections 23 on rings fast on a shaft 22. The projections are arranged in a helical line. When the arm engages a stop, the continued movement of the nut actuates the switch 21 and the motor is reversed. The nut then travels in the opposite direction until it strikes an actuating member 25 which engages a toothed wheel 24 on the shaft 22. The resulting partial rotation of the shaft brings the stop on the next ring into the path of the arm, thus permitting. a longer travel of the nut.

Filed: 1964-06-24
Abstract: 1,069,675. Electric analogue multipliers. BECKMAN INSTRUMENTS Inc. June 24, 1964 [June 25, 1963], No. 26051/64. Heading G4G. [Also in Division G1] In apparatus for providing a signal representing a product of first and second input signals e 1 , e 2  for use with a potentiometric recorder which records the first signal, the slider 23 of a D.C. energized potentiometer 22, which is coupled to the recording element of the recorder, is set to a position corresponding to the input e 1  by a conventional potentiometer system (Fig. 1, not shown). The second input signal e 2  is modulated at 33 and applied via a transformer 27 to the potentiometer 22, so that the output at the slider 23 contains the product e 1 , e 2 . Choke arrangement 28, 29 blocks the modulated signal from the balancing potentiometer system D.C. path while the filter 39 passes the modulated signal but blocks the D.C. The modulated signal is passed via a demodulator 41 which operates in synchronism with the modulator 33 to provide the product output signal at the terminals 44, 45. The modulating and demodulating arrangements 33, 41 may consist of transistor choppers supplied from the A.C. source 34. Capacitor 37 decouples the D.C. supply to the potentiometer 22 and four quadrant operation is facilitated by using balanced positive and negative supplies to energize the potentiometer. In an arrangement wherein several different functions may be simultaneously multiplied by e 1  (Fig. 3, not shown), each function modulates a different frequency carrier. All the carriers are added and passed through the system described. The different carriers are then separately demodulated. In an alternative system a potentiometer system incorporating an A.C. energized rotary differential transformer (70) (Fig. 5, not shown) is used in place of the conventional D.C. energized potentiometer 22. In this system a three-legged core has its centre leg A.C. energized, and a displaceable armature (75) alters the coupling between the centre and the other two legs. The outputs from windings on the other two legs are fed via a differential amplifier (76) and demodulator to a differential D.C. amplifier whose other input is the voltage e 1 . The output from this drives the armature (75) to a balance position. The signal e 2  modulated at a different frequency to the A.C. energizing the transformer is added to the transformer energizing signal, and extracted after multiplication by e 1 , from the output of the differential amplifier (76) by appropriate demodulating and filter arrangements.
