IPC: F02K7/04
Filed: 1953-04-07
Abstract: 739,729. Jet-propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. April 7, 1953 [April 11, 1952], No. 9436/53. Class 110 (3). [Also in Group XXIX] The flow of fuel to a pulsatory jet-propulsion unit is cut off in the event of cessation of operation of the unit by a valve which is held open against a spring by a pressure differential which exists only whilst the unit is functioning. The valve R (see Group XXIX) is inserted in the fuel line 15, 10 and has a pressure-responsive actuator connected by a pipe 19 with a point 32 in the intake E in which a sub-atmospheric pressure obtains during operation. The actuator is also subject, on its opposite side, to atmospheric pressure and has a valved connection 17 with a source of compressed air for initially opening the valve. In modifications, the pipe 19 may lead to a point at which pressure is above atmospheric, e.g. to a tapping in a hookshaped tubular member in front of the entrance to the intake E, or to the combusiton chamber. Also, instead of one of the pressures applied to the valve being atmospheric both may be obtained from different points in the jet-propulsion unit. The valve R may also be responsive to fuel pressure, tending to close with increase of that pressure. Specification 660,144, [Group XXIX], is referred to.

Title: Processes and devices for the demodulation of carrier waves phase modulated by telegraphic signals and the like
IPC: H04L27/233
Filed: 1967-02-28
Abstract: 1,117,724. Data transmission systems. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 28 Feb., 1967 [2 March, 1966], No. 9582/67. Heading H4P. A differentially phase-modulated carrier is demodulated by a logic arrangement in which the carrier is sampled several times in each cycle. The carrier is so modulated that a signal of duration T represents a pair of bits and its phase relative to the preceding period T is (2n + 1) 45 degrees, there being four phases to represent the four possible bit pairs. The carrier frequency is fo = 1/To and period T contains a whole number of half cycles. The received carrier is sampled at intervals of To/8N, N being integral, and each sample is represented as 1 or 0 depending on the instantaneous polarity of the carrier. By use of a shift register fed by the samples binary values x 2 , y 2 , x 1 , y 1  are obtained respectively representing the samples at an arbitrary time t, and at (t-T0/4), (t-T), and (t-T-To/4), Fig. 7 (not shown). These signals pass via respective majority decision circuits to a logic circuit, Figs. 8, 9 (not shown), which derives two bits representing the original bit pair. This is done by four modulo-2 additions, each relating to two of the values x 2 , y 2 , x 1 , Y 1  and their complements, and results in signals m, n p, q, from which, by logical addition and multiplication, signals S 1  (= m + n), S 2 (= p + q), P 1 (= mn), P 2 ( = pq) are derived. The product of each of these signals with its value at a time To/8 earlier is obtained -S<SP>1</SP> 1'  S<SP>1</SP> 2 , P<SP>1</SP> 1 , P<SP>1</SP> 2 - and the logical additions (S<SP>1</SP> 1  + P<SP>1</SP> 1 ) and (S<SP>1</SP> 2  + P<SP>1</SP> 2 ) respectively give the values of the bits of the input bit pair. Further, by modulo-2 addition of the signals P 1  and S 2  at one instant and the values of those signals at a time To/8 earlier, signals P<SP>11</SP> 1  and S<SP>11</SP> 2  are obtained. Modulo-2 addition of these signals provides a synchronizing signal which has an approximate period T.

Title: Improvements in electric switches or circuit breakers of the kind provided with separable electrodes, the arc gap between which is adapted to be swept by a stream of fluid
IPC: H01H33/70
Filed: 1934-03-28
Abstract: 432,453. High tension switches. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, THOMPSON, W. G., c/o General Electric Co., Wembley, Middlesex, and MARX, E., 3, Rankestrasse, Brunswick, Germany. March 28, 1934, No. 9711. [Class 38 (v)] In a switch of the kind in which the arc gap formed on separating the electrodes is swept by a stream of fluid, an orifice is provided at or towards an end of the arc gap, and the fluid, after passing through the orifice, is arranged to flow through a passageway of increasing crosssection but of narrow width, which is adapted to short-circuit the arc if the latter tends to extend therethrough. In one arrangement, Fig. 1, two electrode systems 1, 2 confront each other in a chamber 3 to which fluid under pressure can be admitted from a reservoir 9. The electrode systems are each provided with a cup-like part 4 or 5 having a nozzle orifice, behind which is a metal body 6 or 7 so shaped that the fluid leaving the pressure chamber is constrained to traverse radially a narrow disclike region between the metal body and the rear surface of the associated cup-like part. In the closed position, a metal rod 8 extends through the lower electrode system 2 and makes contact with the upper system 1. The circuit is opened by withdrawing the rod 8 into the electrode system 2, the rod being operated in conjunction with valves controlling the flow of fluid from the reservoir 9. The exhaust conduits 17, 18 are fitted with silencers 15, 16. In a modification, Fig. 2, the upper electrode comprises a fixed cup-like member 22 having an orifice behind which is placed the metal body 23. The lower electrode comprises a cup-like member 24 capable of limited longitudinal movement in a fixed insulating member 21 which carries a metal body 25, placed behind the orifice in the member 24. The member 24 is biassed away from the member 22 by a spring 27, and terminates in a contact member 26 adapted to be engaged by a contact rod 28 in the closed position of the switch. The rod 28 slides through a member 30, having contacts 37 in engagement with the rod, and through a member 31. Compressed air is admitted to the space containing the cuplike members 22, 24 and to the space between the members 30, 31 through a conduit 34. To open the circuit, the rod 28 is moved downwardly, to give a first break at the members 22, 24, and subsequently a break between the rod and the contact 26.
