Abstract: 829,794. Circuits of bi-stable magnetic elements. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Jan. 20, 1958 [March 15, 1957], No. 8599/57. Class 40 (9). [Also in Group XIX] A counter or frequency divider comprises a plurality of counter stages each consisting of a magnetic core counting ring and has auxiliary cores acting to transfer pulses between the counter stages. As shown, Fig. 2, a binary counter comprises stages such as A each comprising two cores A1, A2, coupled bidirectionally by R-C delay networks A11, A13, are interconnected by transfer cores ABC. Input pulses at the terminals CPN are supplied at a frequency nF, where n is the number of stages, to all the transfer cores such as ABC, and to a frequency-divider N, F being the rate at which the first stage A is supplied with pulses. Initially the first cores A1 of each stage are in the " 1 " state, and the second cores A2 are in the " O " state, the auxiliary cores ABC being in the " O " state. Pulses supplied to the terminals CPN tend to switch the cores to the " O " state. In a modification (Fig. 3, not shown), the auxiliary cores ABC and an additional input core for the first stage are fed sequentially from a circulating stepping register.

Filed: 1953-03-31
Abstract: 735,913. Centrifugal pumps ; gas turbines. ROLLS-ROYCE, Ltd. May 14, 1953 [March 31, 1953 ; May 20, 1952], Nos. 8977/53 and 11457/53. Divided out of 735,874. Classes 110 (1) and 110 (3). In a gas turbine installation, having a fuel system comprising a centrifugal pump designed to deliver a quantity of fuel greater than that required in the combustion equipment has a conduit to bleed fuel from the delivery of the pump and to deliver it to a heat exchanger where it is cooled and restricting means in the conduit so that part of the fuel discharged by the pump is delivered to the combustion equipment and part to the heat exchanger. In the arrangement shown, fuel is supplied to the combustion equipment 11 by an engine-driven pump 19 through a pipe line 17, throttle 18 and injectors 15. To prevent boiling of the fuel after it has passed through the throttle 18 due to the excessive heating of the fuel as the result of the reduction of the quantity of fuel delivered by the pump at high altitudes, the pump 19 is arranged to deliver a quantity of fuel greater than the maximum amount required by the engine and the excess fuel is returned to the fuel tank 121 by a pipe line 127 having a fixed area restrictor 128. The fuel tank is cooled and in the arrangement shown, the walls of the tank form the surface of the aircraft wing. In a modification, a cooler is arranged in the pipe line 127 between the restrictor 128 and the tank 121. In a further modification the restrictor 128 is replaced by an hydraulic motor which may be arranged to drive a booster pump 122 or a fuel pressure pump of an auxiliary fuel system. The auxiliary fuel system may supply fuel to the exhaust pipe of a jet propulsion engine or to a reheat combustion chamber arranged between two turbines of a compound gas turbine engine. The conduit 127 may be connected to the discharge volute of the pump 19 and discharge into a low pressure pipe-line upstream of the centrifugal pump 19.

Jackets w may be used to heat the chambers a, and the oil and chlorine may be preheated. The upper end of the topmost chamber may he extended and arranged to form a reservoir for preheated oil and a condenser for vapours from the reaction chambers. Powdered lime may be fed into this reservoir by a worm or other device, and the mixed oil and lime after treatment be passed through a cooler and over a rotary or other filter to separate precipitated sulphur and bituminous matter. The treatment may take place simultaneously with the fractioning or distillation of the oil.

Title: Improvements in apparatus for dropping bombs or other articles from a height, as from aircraft
IPC: B64D1/04
Filed: 1933-03-29
Abstract: 420,594. Bomb-dropping apparatus. THOMSON, A. A. B., c/o Air Ministry, Kingsway, London. March 29, 1933, No. 9513. [Class 9 (ii)] Bombs and other articles are released from aircraft by the direct action of an explosive charge on the member normally preventing the bomb or the like from falling. In one construction, the bombs are held up against crutches 4, 4<1>, Fig. 1, carried by the longitudinal cross members 2 of a frame 1 which is secured beneath the lower wing or body of an aeroplane. The crutches are adjustable lengthwise in slots and vertically by screwed pillars 6. Bomb-supporting devices 7 are secured by pins 20 within an inverted channel member 3 of the frame, and comprise each a body portion 8, Fig. 3, having a vertical slot 9 at one end and a recess 10 adjacent the other. An open ended cartridge 11 is mounted in this recess and is held therein by a looped spring 12. The bomb is supported on a bolt 16, of which one end enters the cartridge and the other end is forked, the arms of the fork embracing a cross-bar 17. Accidental release of the member 16 is prevented by a spring detent 18 and by a pair of plates 19 mounted on either side of the unit and abutting against the ring of the bomb. Release is effected by firing the charge in the cartridge, by closing an electric circuit including leads 30 and terminals 13, 14. A spring 15 forming part of the circuit ejects the cartridge case when the spring 12 is moved down. In a modification the bomb is supported on a pivoted lever the free end of which enters the cartridge. In another construction, a hook 22, Fig. 6, of a pivoted lever 21 supports the bomb, and the upper end of this lever houses the cartridge 11. A forked member 16 sliding in a guide 25 enters the explosive chamber or the cartridge and thereby prevents movement of the lever 21 to release the bomb. When the cartridge is fired, the member 16 is forced upwardly to release the lever which then rotates to release the bomb. A spring- urged rod 27 passes beneath the open end of the guide 25 and thereby prevents the falling of the member 16. In another modification, the bomb is supported by a bent lever the free end of which after passing through the ring on the bomb enters the cartridge chamber. In a further modification the bomb is supported on one arm of a lever, the other arm of which abuts against a rod extending into a cartridge chamber. On discharge the rod is moved to bring a slot therein over the lever which is thus free to pivot and to release the bomb. In all constructions a chamber for the direct reception of an explosive charge may be provided instead of for the reception of a cartridge. Further, the chamber may be provided in the member 16.

IPC: B61G5/08

Abstract: 147,272. Broschart, J. L. April 15, 1919. Stuffing-box joints.-For restoring the air-line pipes of brakes, or steam pipes on railway vehicles &c. to working condition should a break occur, an emergency coupling is employed which comprises a screwed pipe the ends of which are inserted into the sections to be joined, from which are fitted expansible rings which form a fluid-tight joint when expanded by a sliding nut, and the joint also comprises expansible split sleeves, or pivoted arms, with pointed ends which are forced into the tubes to lock the coupling securely in position. As shown in Figs. 2 and 4, the screwed tube 15 is provided with two sets of packing and locking members arranged symmetrically, and each set, after insertion into the pipe sections 16, 17 to be joined, is secured in position so as to form a tight joint between the sections 16, 17, by screwing up sleeves 28 with bevelled ends 30. These act on rings 32 provided with spring arms 33 with curved ends 34 which rest on the tapered ends of rings 24; when moved longitudinally, these force the peripheries of packing-rings 22 into engagement with the interior of one of the pipe sections, the other end of which ring 22 being pressed against a screwed collar 19 locked to the screwed tube 15. Simultaneously with the expansion of the packing rings 22, the curved ends 34 of the spring arms 33 are also expanded, and grip the pipe section. In modified forms, the spring arms 33 are replaced by split rings 36, Fig. 6, with concave peripheries held together by an expansible wire 38; or a single ring with a concave periphery split in two diagonally may also be employed.
