Title: Image recording apparatus
IPC: H04N5/84
Filed: 1949-04-05
Abstract: 662,870. Television. RADIO CORPORATION OF AMERICA. April 5, 1949 [April 17, 1948], No. 9255/49. Class 40 (iii). An apparatus for the photographic recording of images, such as television images, produced in sequence by a scanning beam executing recurrent sweeps, in which the rate of production of images is faster than the intermittent movement of the recording mechanism, initiates a count of the beam sweeps immediately following one such intermittent movement and blanks the beam when a number of sweeps corresponding to a complete image has been counted, the blanking continuing until the next intermittent movement is completed when the beam is restored and a new count started to repeat the recording cycle. In Fig. 2 curve A shows the production of standard television pictures in which the pictures occur at a rate of 30 per second and are each comprised of 525 lines made up by two interlaced fields 31, 32. The recording apparatus, curve B, operates at a frame rate of 24 per second, the film movement occupying <SP>1</SP>/ 150  second. Curve C illustrates the blanking wave which is derived by counting 525 line synchronizing pulses commencing immediately following each film movement. Alternate film frames record two whole consecutive television fields, the other frames recording a whole field and two complemental fractions of a field. In the apparatus, Fig. 1, the composite television signal is applied through a video amplifier and D.C. inserter 21 to cathode-ray tube 10, the screen images being recorded on film 41 pulled through gate 48 by intermittentfeed mechanism 46. Attached to the drive mechanism 51, 52 is a contactor 56, 59 connected to a pulse generator 82 and arranged to generate positive pulse when the feed mechanism has advanced the film to a new frame position. The pulse from 82 triggers a modulator 78 and allows the television line synchronizing pulses, which have been extracted from the composite signal by stages 72, 74 and 76 to pass to a counter 93. The counter is set to a ratio of 525 to 1, and at the end of 525 pulses a negative pulse is applied from the counter back through generator 82 to trigger off modulator 78. In this way, for the duration of a complete television picture, synchronizing pulses are applied through modulator 78 to a rectifier integrator 91 to generate a square wave which is applied through a modulator 103 to control the blanking of the C.R. tube beam. An abrupt termination of the blanking wave is effected by feeding the negative pulse from the counter to modulator 103. A network 96 having a delay equal to the time of one line is included in this connection to extend the blanking wave to the duration of a complete television picture since with a counter set to 525 the 525th line in each picture would be lost. The delay network may be omitted if a counter set to 526 is employed.

Title: Improvements in or relating to the automatic control of the calorific value of gas
IPC: G01N25/28
Filed: 1932-04-05
Abstract: 399,798. Fluid-actuated valves. BRITISH ARCA REGULATORS, Ltd. and LINDSAY, T., Windsor House, Victoria Street, London. April 5, 1932, No. 9773. [Class 135.] The calorific value of a gas is automatically controlled by varying the output of the gasmaking plant in accordance with the variation of the calorific value of the gas, by causing the heat generated by combustion of a portion of the gas, to influence temperature-sensitive means adapted to vary the flow of a portion of the gas flowing to the gas mains, and causing such variation in flow to control the nature or amount of the output of the plant. Assuming that the calorific value of the gas increases, the temperature in a calorimeter C, to which the gas is supplied from a pressure governor 44, rises and expands a sleeve 41 which, by a rod 40, opens valve 42 and admits more gas than formerly to a conduit 9, and, by virtue of a constriction 7, increases the pressure on a diaphragm 11. Levers 13, 14 are thus moved to cause a checking member 15 to approach a discharge aperture 16 of a leak-port relay R similar to that described in Specification 116,074*, [Class 135, Valves &c.]. The slide 21 moves to the right, and permits pressure fluid to enter by a pipe 24 a cylinder 50 above a piston 25, which is depressed, and causes, by a chain 51, a valve 2 in a gas main to open, thus increasing the gas withdrawal rate, which can be arranged to induce a flow of inert gas into the main 1 and reduce the calorific value of the gas. Conversely, when the calorific value of the gas is lowered, the rate of gas withdrawal is decreased. In a modification, the servomotor S and pilot valve P may be replaced by a diaphragm-operated valve which increases the steam supply to the coke to yield an. increased amount of gas of low calorific values. The construction of the pilot valve P is similar to that described in Specification 197,682, [Class 135, Valves &c.].
