Title: Improvements in synchronizing-signal separating apparatus using electron-discharge devices
IPC: H04N5/10
Filed: 1951-03-19
Abstract: 696,308. Television. HAZELTINE CORPORATION. March 19, 1951 [April 26, 1950], No. 6528/51. Class 40 (iii). [Also in Group XL (c)] Fig. 1 shows a television receiver in which it is required to separate line synchronizing pulses from frame, equalizing and noise pulses. The receiver which is otherwise conventional comprises a stage 19 for separating the line synchronizing signals irom the combined synchronizing signals which are present in the output of the synchronizing signal separator unit 17. The receiver comprises an automaticfrequency-control of the line scanning frequency in which a saw-tooth wave is developed in unit 31 by partial integration of the positive pulses obtained from the line scanning circuit output transformer and in which a control voltage is derived by sampling of this sawtooth wave by the'incoming line synchronizing pulse in the phase-detector 33. The incoming pulses to unit 19 are differentiated by network 21, 22 and the resultant narrow pulses are applied to the pentode valve 25 to the screengrid circuit of which is applied a sinusoidal waveform produced by shock-excitation of the resonant circuit 28 by pulses from the line frequency generator 30. Resonant circuit 28 is tuned to the line synchronizing pulse repetition frequency and valve 25 functions as a coincidence circuit so that signals are passed to the output only upon the simultaneous presence of positive going signals at the control and screen grids. Thus, only the wanted line synchronizing pulses are passed to the input of the phase detector 33. In a modification, Fig. 5 (not shown), a double tuned circuit is used and the output signal from the pentode valve is applied to the phase detector via a clipping circuit. In a further modification, Fig. 6 (not shown), the pentode valve has applied to its screen-grid a positive pulse train derived from the output transformer of the line scanning circuit.

Title: Improvements in or relating to electrical servo systems
IPC: G05D3/14
Filed: 1942-05-14
Abstract: 565,116. Electric follow-up control systems. SMITH, C. S. May 14, 1942, No. 6585. [Class 40 (i)] In a follow-up system employing an electric servomotor, the power supply is intermittently interrupted and the armature short-circuited on the approach of the driven member to the desired position, by interacting relays controlled by the follow-up switch. Full power is thus applied to the motor, but the speed is reduced ; the short-circuit on the armature operates as a brake. The control member of the switch comprises a plate 1 mounted on links 2 for sideways movement of a contact 3 carried thereby and the secondary member comprises a conducting crank-pin 9 carrying a contact 10 for engagement with 3. The control member 1 also carries additional contacts 5, 6 pivoted on the plate and urged by springs 7 against a stop pin 4 on the plate, the crank-pin 9 being normally out of engagement with the contacts 5, 6. The arrangement is such that when the control member undergoes large displacement so that contacts 3, 10 disengage, the engagement between 9 and 5 or 6 as the case may be operates through relay set 12 to cause the application of power to motor 11 which drives the controlled shaft 17 and also a transmitter 18 of an electric link, the receiver 19 of which restores the crank-pin to its normal position relative to the control member. When the relative displacement is reduced to the point at which contact is made both at 9, 5 (or 6) and 10, 3, the relay set intermittently cuts off the power supply and short-circuits the armature, until in the normal position contact at 9, 5 (or 6) is broken. The electrical link may be replaced by a mechanical one. Circuit arrangement, Fig. 4. The crank 9 and contact 10 are represented by a single contact 9. Normally, relay 36 is short-circuited over contacts 42, 57 of relays 35, 37, one of which is operated when 9 leaves 3 and engages 5 or 6 to remove a short-circuit on motor armature 31. When the position has been restored to the extent that 9 engages both 3 and 5 or 6, relay 36 pulls up and interacts with 35 or 37 to effect the operations described above. Limit switches 33, 34 may be provided. The speed (motor action) of the release may be altered by including resistances 38, 39 which also improve the operation of interaction.
