Abstract: 1371899 Fluid-pressure servomotor systems NORMALAIR-GARRETT (HOLDINGS) Ltd 4 Nov 1971 [20 Nov 1970] 55348/70 Heading G3P [Also in Division F2] A pressure-regulation valve 14 is controlled by a piston 16 subjected to a datum pressure in a chamber 25 and to the downstream pressure communicated through apertures 26 with chamber 24. The datum pressure is derived from inlet flow delivered through passage 29, and is controlled by a reducing valve 32 having a restricted discharge 33, and by a bleed valve 34. The bleed valve is adjusted by variations in downstream pressure via diaphragms or piston means 35, 36 communicated with the downstream pressure via line 31. Departure from the selected downstream pressure causes appropriate movement of bleed valve 34 to alter the datum pressure in the appropriate sense, resulting in corrective movement of the valve 14. The restriction in passage 38 causes the rate of response of the bleed valve to follow the rate of change of the downstream pressure.

Title: Supervisory Signalling Apparatus for Graphic Communication Systems
IPC: H04N1/327
Filed: 1966-12-19
Abstract: 1,174,785. Facsimile transmission system; pulse signalling. XEROX CORP. 19 Dec., 1966 [27 Dec., 1965], No. 56660/66. Headings H4F and H4L. In a data transmission system employing transceivers at each terminal, periods of data transmission are separated by periods which are sub-divided into a plurality of intervals allocated to both forward and reverse supervisory or control signals. Thus, from one terminal there is transmitted the forward supervisory signal from the transmitter to the receiver of the second terminal and a reverse supervisory signal from the receiver to the transmitter of the second terminal. The invention is said to be of general application, but is described in detail only as applied to a facsimile system in which the flyback periods 25 which separate the line scan periods 23, Figs. 2A and 2B, are sub-divided into a plurality (n) of intervals, Fig. 3A, allocated to the supervisory or control signals. These are timed by single pulses, as illustrated in Figs. 3A, 3B and 3C for the first three intervals, and comprise combinations of pulses (forming binary " words "), as illustrated in Figs. 4A and 4B for the second interval. The specific embodiment of the invention which is described is a duplex system permitting simultaneous transmission in both direction and incorporating the staggered scan operation in odd and even lines which forms the subject of Specification 1,127,048. The signals illustrated in Figs. 4A and 4B are employed to synchronize the operations in alternate lines. Other control signals are concerned with forward and reverse supervision and control functions, such as " in sync." condition, presence of document in scanner, length of document to be scanned &c. The number of supervisory and control signals may be such that more than one flyback period is required to accommodate them. Detailed arrangements are described (in block diagram form only) with reference to Figs. 5-7 (not shown). The arrangements are timed by clock sources and digitize the facsimile signals in both time and amplitude. The control signals are inserted in the flyback periods by means of a shift register circuit which is actuated at the appropriate times from the block source and has its stages preset in an appropriate pattern by a diode matrix so as to cause the production of combinations of pulses in accordance with the required control signals. A similar arrangement is used to separate and distinguish the signals during reception. Scanning for transmission may be effected by a cathode-ray tube flying-spot scanner. Reproduction may be effected by a cathode-ray tube xerographic apparatus.

Filed: 1973-12-19
Abstract: 1453069 Automatic control of registration BROWN & WILLIAMSON TOBACCO CORP 19 Dec 1973 [20 Dec 1972] 58837/73 Heading G3R [Also in Division H2]  To cut a cigarette paper 16 in register with marks pre-printed thereon the speed of a rotating knife 18 is adjusted by a system in which lag, lead, or in-register pulses are formed in a controller 26 from the pulse output of a mark detector 24 and knife shaft encoder 28, the simultaneous occurrence of a knife pulse and a lag or lead pulse being entered in a reversible counter whose count is then entered into a store and also effects a step change in knife speed, while the simultaneous occurrence of a knife pulse and an in-register pulse causes the store to be read into the counter to cause adjustment of the speed to the stored value. The operation is such that speed adjustments are made in steps until registration is achieved, whereupon the speed is re-adjusted back to the penultimate step. Correction is effected by a stepping motor 30 driving one input to a differential gear 32, the other input to which is a constant speed drive and the output drives the knife. The knife speed encoder produces two sets of  pulses, one at 500 per revolution and the other at one per revolution. The latter acts as an enabling pulse for a counter, in which an appropriate one of the 500 is selected by thumb wheel switches. This selected one is compared in time with a pulse from the photo-electric mark detector 24, using logic circuits. The arrangement is such that each time the selected knife pulse lags or leads the mark pulse a reversible counter is stepped by one step. The count is supplied to the store and to a pulse rate multiplier which thus produces pulses whose frequency adjusts, in steps, to the magnitude of the error; these pulses are applied in the appropriate directional sequence to the stepping correcting motor. This may run continuously, to rectify errors due to paper stretch &c. The logic circuits also provide pulses to a registration indicator, comprising a rotating neon tube which flashes at instants corresponding to lag and lead errors, and the instant of cutting. This enables manual adjustment when starting the machine.
