Title: Improvements in and relating to pneumatic apparatus for raising liquids
IPC: F04F1/06
Filed: 1939-05-18
Abstract: 528,988. Raising liquids. CLEMENTS, H., HOLMES, F. B., and HOLMES & CO., Ltd., W. C. May 18, 1939, No. 14887. [Class 102 (ii)] In pneumatic apparatus for raising liquids in which a pair of ejector vessels are alternately filled with liquid and then discharged by compressed air, the admission of air to the vessel to be discharged and its withdrawal from the vessel to be filled is controlled by a single rotary valve element having a plane seating surface incerposed in the passages affording communication between the respeccive vessels and the suction and delivery sides of the air compressor. In the form shown, the control valve comprises a seating 15 for a circular disc valve element 19 and three ports spaced 90 degrees apart. Two diametrically opposite ports 16, 17 (not shown) are connected by passages 16a, 17a to the ejector vessels, whilst the third port is connected by a passage 18a to the suction side of the air compressor, the delivery of which is connected to a supply 26 above the valve element 19. The latter is formed with a kidney-shaped through port 23 and on its underside with a Kidney-shaped passage 24, rotation of the valve element being restricted to 90 degrees by means of a rib 25 co-operating with a pair of lugs on the valve cover 14. The valve element 19 is held in position by a spring 22 and is mounted on a shaft 20 which is connected through a friction coupling 30 with a shaft 29, reduction gearing 28, and a pneumatic or electric motor 27. The coupling carries a pair of projections 31 spaced 90 degrees apart so that as the valve element 19 reaches its correct end positions, one of a pair of limit switches 32, 32a is opened to stop the motor, whilst the other is closed in readiness for rotating the valve element to its other position when the appropriate ejector vessel is filled ready for discharging and its float-actuated limit switch 36 or 37 is actuated.

Title: Improvements in or relating to electric pulse generating apparatus
IPC: H03K5/00
Filed: 1953-05-29
Abstract: 767,685. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and BAYLISS, A. J. May 24, 1954 [May 29, 1953], No. 15017/53. Class 40 (4). [Also in Group XL (b)] In an arrangement comprising a closed loop containing a delay line for producing a recurring pulse whose position is determined by that of an input trigger pulse, the application of a second trigger pulse automatically clears the first out of the system. As shown, Fig. 1, a pulse present in the delay device 1 is recirculated via gates 7, 8 and amplifiers 2, 9, the former gate being fed by a master pulse generator 8 producing all the pulse trains interlaced, and passing only that pulse train coincident with the pulse output from the delay device. Gate 6 is normally open. When a second trigger pulse is applied from the source 5 it enters the circulating system in the normal way and is also passed to a differentiating and clipping circuit 12 for producing a pulse coincident with its leading edge. This pulse on passing through the gating circuit 11 operates a bi-stable trigger circuit 13 whose output thereupon closes the gate 6 to remove the original pulse from the circulating system. A pulse coinciding with the trailing edge of the latter, obtained from the differentiating and clipping circuit 14 restores the trigger circuit 13 in time to open the gate 6 for the newly introduced pulse. Since the differentiating and clipping circuit 12 produces a pulse on each circulation of a pulse in the system, the gate 11 is arranged to be closed at that time by a pulse from the output of gate 7, so that the trigger circuit 13 is affected only by newly applied trigger pulses. The delay device may be of the magneto-strictive kind and may consist of a bundle of fine nickel wires soldered together at their ends and having input and output coils one at each end. Means is provided for holding the gate 11 closed for a period of at least one cycle when the first pulse is injected into the system. The Provisional Specification describes an arrangement in which the pulse is converted into supersonic form for transmission through a delay line of aluminium alloy, quartz or mercury. The trigger pulse is arranged to be injected into a gating circuit positioned as at 7 and the input lead to the gating circuit 11 is taken from the output side of the delay line. Specification 767,684 is referred to.

Abstract: 504,507. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. May 20, 1938, No. 15107. Convention date, June 11, 1937. [Class 40 (v)] An elevated aerial system for transmitting a vertically-inclined beam, suitable for guiding an aeroplane to ground, consists of two dipole aerials 1, 2 spaced apart by half a wavelength in the vertical plane, a reflector 3 in the same vertical plane and spaced a quarter wavelength away from the lower dipole 1, and a second reflector 4 at the same distance from the dipole 1 and in the same. horizontal plane. The system gives a vertical radiation-field of the form shown in Fig. 2, the direction of the "zero-feld" axes 1Y, 1X being varied by altering either the phase or amplitude, or both, of the currents in the dipoles 1, 2 without involving any mechanical displacement of the aerial elements. This allows the mean slope of the lower portion of the lobe F to be controlled and also the width of the lobe as a whole. The arrangement also minimizes the "back lobes F2, F3 and reduces reflection from the ground.
