Title: Improvements in jet propulsion engines including at least one control device for temporarily modifying the operation of said engine
IPC: F02K3/00
Filed: 1954-03-19
Abstract: 754.854. Gas turbine plant. SOC. D'EXPLOITATION DES MATERIALS HISPANO SUIZA. March 19, 1954 [March 20, 1953], No. 8129/54. Class 110(3) A jet propulsion engine having a control device operated by a servomotor using fuel supplied by the fuel feed pump as a power liuid has the power liquid taken from a by-pass between the discharge and suction sides of the feed pump through a reducing valve and an automatic valve device which is responsive to fuel admission to the servomotor to reduce or stop the flow of fuel through the by-pass. Fuel from a tank 1 is supplied by a pump 2 to main fuel injectors 3 and by a pump 4 to reheat fuel injectors 5. The pump 4 is controlled by an hydraulic servomotor 6 which is supplied with actuating fluid bled from a by-pass conduit 7 around the pump 2 to avoid any ill effects of the operation of the servomotor 6 on the fuel supply to the engine. The servo fluid is supplied through apparatus 8, Fig. 2, which comprises a spring-loaded slide valve 9 which maintains the pressure at its downstream side constant and a slide valve 16. The slide valve 16 controls the flow through the conduit 7a to the suction of the pump and the supply 18 to the servomotor 6. When the servomotor 6 is not in operation, the slide valve occupies the extreme righthand position and fuel flows through the by-pass circuit which includes conduit 7, chamber 11. orifice 13, chamber 15 and conduit 7a. When the servomotor is operated liquid is drawn from the chamber 15 and the orifice 13 causes a pressure drop in the chamber and slide valve 16 moves to the left and gradually closes the inlet ports to the conduit 7a and thus reduces the flow through the by-pass. After operation of the servomotor 6, the pressure in chamber 15 builds up and spring 17 pushes the slide valve 16 to the right and restores the flow through the by-pass. The valve 16 may be provided with slots 16a to prevent the action of the valve being too abrupt. The loading of the springs 10, 17 may be adjustable. To avoid a delay in starting due to the presence of the by-pass circuit, a valve 19, which is opened only when the speed of the engine reaches a predetermined value, may be provided.

Title: Digital data processors
IPC: G06F9/32
Filed: 1975-02-26
Abstract: 1493313 Data processing INTERNATIONAL BUSINESS MACHINES CORP 26 Feb 1975 [6 May 1974] 8141/75 Heading G4A In response to the decoding of a given instruction, control is passed from the instruction decoder to a feedback shift register which generates a sequence of instructions, the particular sequence generated being dependent on the initial word loaded into the register 20-28 and the modulo 2 (exclusive OR) feedback paths selected, e.g. by a control word in a register 50. Figs. 5A-5C (not shown) illustrate a practical embodiment in which a general purpose computer can operate in a first mode in which instructions of a program are sequentially accessed from memory using an instruction counter, each instruction so accessed being entered in an instruction register and its OP code decoded in the normal way. An instruction which calls for a subroutine causes a switch to a second mode of operation in which a sequence of instructions is generated by the feedback shift register. Different fields of the subroutine initiating instruction are first entered into appropriate registers for use as the initial word of the instruction sequence, the feedback control word, and as a prefix to the sequence generated by the shift register. Each instruction word generated by the shift register is decoded, together with the prefix to control the operation of the computer. Certain words in the sequence may be interpreted as conditional branch instructions which, if the conditions are satisfied, reset the shift register to another state in the same or a different sequence. At the end of the subroutine(s), which may be signalled by the shift register being set to all zeroes, the first mode of operation is returned to. Exemplary routines for evaluating square roots and polynomials are described. There may be several instruction sequence generating shift registers operating either in parallel or in a hierarchy in which the arrival of one shift register in a given state activates, e.g. shifts another shift register.

Abstract: 608,593. Reinforcements for concrete. SOC. DES GRANDS TRAVAUX DE MARSEILLE. April 4, 1945, Nos. 8367 and 8368. Convention dates, Sept. 30, 1943 and May 12 1944. [Class 20(iv)] A prestressed reinforcement for concrete comprises a sheath under tension and a core, which is ultimately removable, under compression, the ends of the sheath and core being locked together whilst the concrete is setting, and is characterized by the reinforcement being readily bent into a desired configuration. The sheath may consist of parallel wires 1, of any desired section, held together by spaced hoops 3 or by a coiled wire, and the core 2 may be a continuous rod, with or without hoops, or it may be a close packed, helical squaresectioned wire spring. The wires 1 are locked at each end in a head 4 of metal or hooped concrete, hooks 5 being embedded in the head so that tension may be applied to the wires 1 by a jack which reacts on and compresses the core 2. The sheath and core are maintained in stressed condition by a key bolt 6 which is inserted before the removal of the jack, and is knocked out after the concrete has set. In Figs. 5, 6, the core consists of parts 18 shaped to permit bending of the sheath, and kept together by balloon springs 19<1>. The sheath consists of twisted and braided wire 12 and the ends of the sheath are sealed in a fusible material 16 in the space between an outer sleeve 14 and an inner tapered sleeve 15. The stresses are applied to the core and the sheath by a jack which acts between the inner end of the. sleeve 14 and the end of a push rod 10 which bears on the core. After tension is applied to the sheath, the nut 21 is screwed into contact with the rod 10 and the jack is removed. The tensions are released when the concrete has set, by melting the material 16 by an electric heater 22. According to the e Specification as open to inspection under Sect. 91, the core may consist of hard metallic pellets or a bundle of hard parallel. wires. This subject-matter does not appear in the Specification as accepted.
