Abstract: 1521108 Sensing pressure in a fiber layer MASCHINENFABRIK RIETER AG 17 Oct 1975 [1 Nov 1974 30 Sept 1975] 42661/75 Headings D1F and DIN In a fiber handling machine a cover plate 7 is located over a fiber layer 14 on a moving surface 5, e.g. a carding cylinder, and pressure variations are measured under the plate 7. Such pressure variations are proportional to the thickness of the fiber layer and are used to control the speed of suitable elements of the machine, e.g. the feeding arrangement, carding cylinder, doffer or drawing device, and hence even out variations in fiber layer thickness. A swelling out on the plate 7 provides a throttling effect with a pressure increase at A and decrease at B, the difference can be used as the measured valve. This valve is compared with a preset desired valve and retroactive control is applied. Pressure sensing bores 9, 21 may be located across the width of the fiber layer, or a single bore can communicate with a transverse groove in the cover plate 7.

Title: Thrust reverser for a gas turbine engine
Inventor: MORTLOCK JAMES OSWALD
IPC: G01F23/16
Filed: 1968-09-11
Abstract: 1,209,098. Thrust reversers. ROLLSROYCE Ltd. 11 Sept., 1968, No. 43257/68. Heading B7G. A thrust reverser for a ducted fan engine comprises an outer easing 12 supported by struts 13 from an inner casing 11 which contains the engine compressor and turbine. The outer casing 12 has an aperture at 22 through which air from the fan 14 may be deflected to give reverse thrust. During forward thrust the aperture is covered by an axially movable sleeve 34, and by flaps 26, 27, 42 and 43. Flaps 26 and 42 are pivotally connected to a bracket 33 on the sleeve 34, while flaps 27 and 43 are pivotally connected to the rear part 21 of casing 12 at 31; flaps 26 and 27 are pivotally connected to one another at 30. Rams 25 are connected by rods 36 to the sleeve brackets 33 so that to reverse thrust the sleeve 34 may be moved to the position shown in chain lines, causing the flaps to pivot to a position 25 in which they prevent axial exhaust from the duct 15; in the aperture 22 so exposed are vanes 24 shaped to deflect forwardly the air flowing through the aperture. The brackets 33 may either pass through slots in beams 23 on which the vanes 24 are mounted, or may pass between adjacent beams 23. Because the circumference of casing 11 is less than that of casing 12, flaps 26 and 27 are trapezoidal, this, and the manner in which gaps between adjacent  flaps 26 or 27 are sealed by overlapping flaps 42 or 43 being shown in Fig. 2. Another embodiment, Fig. 4, has the overlapping flaps hinged to the edges 37 of the flaps 26, 27 shown in Fig. 2, and also hinged along their centre lines. In a further embodiment, Fig. 5, that part of the aperture not blocked by flaps 55 is blocked by flaps hinged about axes parallel to the duct axis; in this case the flaps 55 are operated by rods 54, and the longitudinal flaps are arranged to be pointed radially into the duct during reverse thrust by rods (not shown) connected to the sleeve bracket.

Title: Gas turbine jet propulsion engine
Inventor: JOHNSON CHRISTOPHER LINLEY
IPC: F02K3/02
Filed: 1968-09-11
Abstract: 1,175,037. Jet propulsion engines. ROLLSROYCE Ltd. Sept.11, 1968, No.43258/68. Headings F1J. [Also in Division G3] A gas turbine jet propulsion engine comprises conduit means in which are arranged in flow series combustion equipment and variable area nozzle means; means for measuring the dynamic pressure in the conduit means upstream of the combustion equipment; and means, acted upon by the measuring means, for controlling the nozzle area. The engine shown comprises front nozzles 14, 15 and rear nozzles 22, 23, all rotatable to vary the efflux direction. The nozzles 14, 15 receive air from the L.P. compressor 3, and their thrust can be increased, e.g. for vertical take-off, by supplying fuel to injectors 16, 17 from a vapour core centrifugal pump 34 having an inlet throttle 36 controlled by at least one engine variable and pilot's lever 39. The area of each nozzle 14, 15 is adjustable by a ram 18 connected by pipes 49 to the high and low-pressure sides of a swash-plate pump 48. For this purpose, the inclination of the swash-plate 47 is adjustable by a piston 40 subject on one side 43 via a duct 45 to a high-pressure, e.g., that of the fuel supply to the main combustion equipment 5, and subject on the other side 44 to a variable pressure intermediate the high-pressure in the duct 45 and a low-pressure in a chamber 50 connected to a low-pressure source. This variable intermediate pressure is established by a potentiometer comprising a fixed restriction 46<SP>1</SP> and a variable restriction 51, the latter being controlled by a valve rod 52 which is rotated to avoid stiction and is adjusted axially by a bell crank 53, 54 bearing against a roller fulcrum 62 and pivotally connected to the casing through a link 60. The bell crank 53, 54 is acted on by opposed diaphragms 63, 64, both of which are acted on one side by the total pressure of the air at a point 73<SP>1</SP> immediately upstream of the region of the fuel injectors 16, 17, communicated via a duct 73 to a chamber 66. The other side of diaphragm 64 is acted on by the static pressure at the point 73<SP>1</SP>, communicated via a duct 74 to a chamber 67, while the other side of diaphragm 63 is acted on by the pressure in a chamber 65, established by a potentiometer 68, 69 connected between the chamber 66 and a duct 70 open to atmosphere. The net force on diaphragm 64 therefore represents the dynamic pressure at the point 73<SP>1</SP>, while the net force on diaphragm 63 represents the dynamic pressure at the fuel nozzles 16, 17 (once this dynamic pressure is a fixed fraction of the total pressure when the fuel nozzles are choked). Accordingly, the control of the area of the nozzles 14, 15 maintains the ratio of these two dynamic pressures at a constant value.

Abstract: 1445002 Selective signalling SOC INDUSTRIELLE DE LIAISONS ELECTRIQUES 14 Sept 1973 [16 Jan 1973] 43376/73 Heading G4H  In a monitoring system in which a central station interrogates a plurality of substations over a two-wire line, the identity of a substation giving a given response signal to the central station is determined by counting the time from the origin of the interrogation signal to the receipt at the central station of the response signal, the position of a signal within the response signal indicating the state of the substation, A.C. being applied to the line to charge accumulators in the substations and to provide a clock signal for the substations and central station. To start an interrogation cycle, the central station interrupts the positive halfcycles of this A.C. for 200 ms. and this starts counters at the substations counting the A.C. cycles. Each station responds at a characteristic count to interrupt the positive half-cycles again at one of two positions in a respective time-slot depending on the state of the substation apparatus. A counter at the central station, counting in synchronism with the substation counters, routes the state information to storage and displays. A manual test circuit with lamp is provided in each substation.

Abstract: 932,169. Electric selective signalling. GENERAL ELECTRIC CO. Ltd. Nov. 27, 1961 [Dec. 16, 1960],.No. 43492/60. Class 40 (1). The invention provides a system for signalling between the winder house and the cage in a mine lift. At the transmitter, a recurring sequence of 7 pulses is obtained from a phasediscriminator transformer 6 having saturable cores, which is fed from a 3-phase supply. By virtue of diodes 10 the sequence appears as a 14-pulse cycle, alternate pulses having opposite polarity. Closure of certain of switches 11 causes a train of pulses having +, -, or zero polarity to be passed to the receiver. Units 13 reverse the sign of pulses fed to alternate coincidence gates 12 which are also supplied by a 14-pulse recurrent pulse train, this being derived by a transformer 14 similar to transformer 6 and supplied from the same source. Certain of units 12 will pulse, in correspondence with the closed switches 11. The outputs of units 12 are fed, via suitable delays, to a number of coincidence gates. According to the particular switches 11 which were closed one of the coincidence gates will give a control signal. In a second embodiment, Fig. 2 (not shown), communication in either direction is obtained, the pulse signals modulating an ultrasonic carrier-wave. Each transformer has an additional winding which serves to block the receiving units at the winder house or at the cage while data is being transmitted to the cage or to the winder house, respectively.
