Title: Improvements in or relating to Afterglow Correcting Circuit Arrangements.
Inventor: MILLWARD JOHN DAVID
IPC: H04N5/257
Filed: 1966-12-20
Abstract: 1,198,620. Television. RANK ORGANISATION Ltd. 22 Nov., 1967 [20 Dec., 1966], No. 57027/66. Heading H4F. In television film scanning apparatus to reduce the afterglow component in the video signal resulting from the optical decay of the phosphor of the scanning cathode-ray tube the video signal is fed to an amplifier 2, the output of which is applied in parallel via adjustable potentiometers 20-26 to a plurality of differentiating circuits 10-16 each comprising a common resistor 42 and a capacitor C connected in series with an amplitude limiting resistor R, and the outputs of the differentiating circuits are combined in amplifier 32 with an output from amplifier 2 derived via a signal level equalizing resistor 30. The differentiating circuits have different time constants, the combination of which is effective to match the complex time constant of the afterglow component. During operation complete afterglow correction is obtained by adjusting the relative levels of the inputs to the differentiating circuits by means of potentiometers 20-26. The differentiating circuits are arranged to provide a different degree, ranging from coarse to fine, of correction by suitable choice and adjustment of their parameters. The output of amplifier 2 and the input of amplifier 32 have very low (substantially error) impedance, thus ensuring minimum interaction between the differentiating circuits even though they share common resistor 42. The input of amplifier 2 and the output of amplifier 32 are matched to the characteristic impedances of their co-operating circuits. The values of the resistances of the potentiometers are low compared with the values of the corresponding resistors R so that adjustment of each potentiometer gives a linear response. A.C. coupling errors are avoided by employing resistors 40 and 42.

Title: Shutter device
IPC: G03B9/70
Filed: 1970-12-01
Abstract: 1327940 Photographic shutters CANON K K 1 Dec 1970 [1 Dec 1969 12 Dec 1969 18 Dec 1969 27 Dec 1969] 57047/70 Heading G2A A shutter device has a blade ring 3 arranged to move so that the shutter blades 3' open at a constant rate, and a flash synchroniser switch which is closed by the blade ring when the blade opening reaches a value determined for an appropriate flash exposure. A shutter release lever 2 is depressed in the direction of arrow A so that a stepped portion 2b engages with and rotates a latch member 13 to free control lever 14. A main switch 12 is closed to energize an exposure control circuit and an electromagnet 28 and an anchor 18 of a delay device starts to move. A gear 17, with a pin 19, starts rotating in a clockwise direction under the action of a spring (not shown) and frees lever 16. The blade ring 3 thus rotates under action of a spring 30 and the shutter opens at a constant rate. For EE photography, opening of contacts 42 allows a condenser to charge at a rate determined by scene illumination incident upon a photo-conductor. At the end of the exposure interval, an electromagnet 28 is de-energized. Lock pawl 26 is freed for rotation (lever 20 having been previously rotated by bottom end portion 2c of shutter release 2) and a convex end 26a thereof engages and rotates lever 16 counter clockwise and thus closes the shutter. The maximum value of the opening of the shutter is indicated in a viewfinder 46 by a lever 44 which is frictionally pivoted and reset by member 47. For flash operation, a change-over ring 29 is positioned according to the film guide number, and at the same time switches a fixed resistance in place of the photo-conductor in the control circuit to give a fixed shutter time. A distance ring 39 is also adjusted to the object distance. An adder member 4 rotates about a pin 7 during these movement so that a contact member 40 thereon lies in the path of movement of a pin 41, the position of contact member 40 thus determining the aperture opening of the shutter and at the same time ensuring that the flash occurs when the shutter is at the maximum aperture. The shutter is designed to allow for the rather long time-to-peak characteristic of a flash bulb. Alternatively, a flash discharge tube is used, and arrangements are described, Fig. 9-12, (not shown), using a contactless synchronizer, either associated with the electronic timing circuit or using a lamp which illuminates a phototransistor in the discharge tube trigger circuit, the lamp being lit upon de-energization of the electromagnet 28.

Abstract: 1,136,440. Train detector. COMPAGNIE DES FREINS ET SIGNAUX WESTING- HOUSE. 21 Dec., 1966 [5 Jan., 1966], No. 57208/66. Heading B7N. An arrangement for detecting the presence of a metallic mass, e.g. a train, comprises a number, e.g. three transistor oscillator circuits 1, 2 and 3 of similar form but operating at different frequencies arranged such that their respective tuning coils 20, 21; 51, 52 and 70, 71 are disposed in line adjacent and parallel to a railway track and connected such that the output signal of each oscillator controls the generation of a signal in the following oscillator and the last oscillator controls the generation of a signal from an output stage 82. The presence of a train wheel adjacent a tuning coil stops the associated circuit oscillating with the result that the following oscillators are cut off and the output stage, in the absence of an input signal, signals the presence of a train. The detection zones of the respective tuning coils overlap and the overall length of the arrangement is greater than the length of a train vehicle wheel base. The tuning coils are wound on ferrite rods 100 and supported on a plate 109 beneath the head of rail 107. The coils are partially screened by a metal bracket 108 and the associated circuits are embedded in a block 110 of epoxy resin disposed beneath the plate 109.

Title: Data transmission apparatus
IPC: G11B20/14
Filed: 1968-12-04
Abstract: 1,213,688. Data storage. INTERNATIONAL BUSINESS MACHINES CORP. 4 Dec., 1968 [15 Jan., 1968], No. 57457/68. Heading G4C. In data transmission apparatus, an error indication is given if signals occur during particular portions of clock intervals or fail to occur during the clock intervals, the clock intervals being derived from the signals. A phase-encoded data character read 21 from a moving magnetic store consists of a start bit 0, seven data bits, and an end bit 1. Each bit is represented by a positive or negative data transition in the centre of the bit cell for bit values 1 and 0 respectively, corrective transitions being provided at the cell boundries as necessary, the signal being at the lower level before and after the character. Each positive or negative transition sets flip-flop 23 to its left or right state respectively unless it is already in that state, such state changes each producing an output pulse at the upper left or right output of the flip-flop respectively. Every state change also produces an output pulse at the upper central output. The transitions at the beginning and centre of the start bit cell are detected at 25 to actuate sync circuit 29 and enable AND 31 to pass any pulse from the central output of flip-flop 23 occurring during time S 3  to actuate sync circuit 29. Whenever sync circuit 29 is actuated, it produces a sync pulse which is counted at 32 and initiates a chain of monostables 33, 35, 37 and 43 or 45 to produce strobe pulses S 1 , S 2 , S 2a  in turn, followed by S 3  if counter 32 indicates the end bit has not been reached or S 4  if it has. Each sync pulse occurs at the centre of a bit cell (in the absence of error) and the strobe pulses produced from it follow it in contiguous non- overlapping-relationship, pulse S 3  or S 4  being terminated by the next sync pulse (or after a predetermined time if the sync pulse does not arrive). An error latch 51 is set if a pulse is produced from the central output of flip-flop 23 during pulse S 1  or S 2a , or if one is not so produced during pulse S 3 , or if a pulse is not produced from the left output of flip-flop 23 during pulse S 4 . Thus in fact a check is made that positive and negative transitions follow each other alternately, that transitions do occur at or near the cell centres, that transitions do not occur except at or near the cell centres and boundaries, and that the number of transitions is correct (by checking the sense of the transition at the centre of the end bit cell).
