Title: Television test signal generator
IPC: H04N17/00
Filed: 1962-11-13
Abstract: 961,913. Television; transistor pulse circuits. NORTHERN ELECTRIC CO. Ltd. Nov. 13, 1962 [Dec. 4, 1961], No. 42935/62. Headings H3T and H4F. The invention relates to a television test signal generator for use in conjunction with a television synchronizing generator of the type which is locked in frequency and phase to a sinusoidal signal A, Fig. 3, of field-scanning frequency and which also furnishes trigger pulses G at twice line frequency, and is concerned with the production of a test signal, which when applied to an image reproducing device, produces an image as shown in Fig. 2, comprised of a rectangular white area within a black field. The general procedure is to develop a sinusoidal signal D of adjustable phase with respect to reference signal A and to limit the signal at an adjustable level in an amplifier to furnish a waveform E of greater duration than the normal vertical blanking signals C. This signal constitutes the field frequency component of the test signal, adjustment of the phase of signal D controlling the vertical position of the white area and adjustment of the limit level controlling the vertical dimension of the area. The line frequency component of the test signal is obtained by dividing the frequency of the trigger pulse train G by two, using a monostable circuit to obtain a waveform H and then differentiating and limiting this waveform as at I and J to produce a waveform of duration greater than that of the normal line blanking pulses F. Adjustment of the trigger time of the monostable circuit controls the duration of waveform H and the horizontal position of the white area, whilst adjustment of the time-constant of the differentiation circuit controls the horizontal dimension of the area. Waveforms E and J are combined as at K and limited to produce the complete test signal L. A circuit for carrying out the invention is illustrated in Fig. 4 where the reference sinusoidal signal is applied through transformer T, and adjustable phaseshifting circuit S, R1, C1 to a limiter stage Q1 with the base returned to an adjustable bias network R3-R5, and the trigger pulses at twice line frequency are applied to monostable circuit Q2, Q3, Q4 of adjustable time-constant C3, R12, the output from which is differentiated in a circuit C4, R15 of adjustable time constant and then limited in stage Q5. Waveform E is produced at the collector of stage Q1, and waveform J is produced at the collector of stage Q5, the two waveforms being added in network R16, R17, R20, R21 and limited in stage Q6 to produce waveform L at the output. A feedback connection from Q5 via diode D2 to the base of Q2 prevents the monostable circuit responding to alternate trigger pulses F.

Abstract: 1489828 Stop-on-signal tuning systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Oct 1975 [14 Jan 1975] 43801/75 Heading H3Q In a stop-on-signal tuning system the search is under the control of a counter which counts at a fast rate when outside the desired waveband and at a slower rate within the waveband. The counter 11 controls a circuit 9 such as a potentiometer store, a digital to analogue converter or a frequency synthesizer to provide a tuning signal for the receiver tuning section 3. Circuit 19 determines which waveband is being searched, applying a corresponding signal to the tuning section 3 and a comparison circuit 39 which compares the signal with a desired waveband selected by switches 59, 61, 63, 65. Counting pulses are applied to counter 11 at a high frequency until circuit 39 detects coincidence. Switch 71 is then operated to make counter 11 count more slowly through the desired band. When the desired station is reached, switch 77 is opened to stop the search. Use of an UP/ DOWN counter for counter 11 permits the direction of search to be reversed at the end of the desired waveband. Detailed logic circuits for units 39, 57, 71 and 77 are described, Fig. 2 (not shown).

Abstract: 1,234,715. Fluidic relay. BARDONS & OLIVER Inc. 8 Sept., 1969, No. 44340/69. Heading G4P. A fluidic relay comprises a housing having a chamber vented to atmosphere, axially aligned inlet and outlet tubes 14, 14<SP>1</SP>, 15, 15<SP>1</SP> projecting into the chamber and spaced so that relatively high pressure fluid can flow linearly from one to the other, and interrupter means 32 movable to block said linear flow in response to a relatively lower pressure. The lower pressure fluid presses a diaphragm (Fig. 3, not shown), which causes a flexible member to move the means 32 up or down. In Fig. 4 projections 33 and 34 of the means 32 block one flow as the other is unblocked but only one pair of tubes may be provided as in Fig. 6. Here the lowpressure signal is fed into a bellows which moves a rod 50 between the high-pressure tubes 54, 55. When the low-pressure signal is removed the time of collapse of the bellows determines the interruption time, and this time may be varied using an adjustable screw-threaded member 57, holdable by spring-loaded screw 64, which engages with the end of rod 50. The high-pressure flow may be laminar or turbulent. The relay may be used in machine tools.
