Title: Improvements in or relating to aircraft power plant installations incorporating gas-turbine engines
Inventor: HOLLINGS JOHN SHAW
IPC: F02K1/30
Filed: 1954-04-27
Abstract: 795,651. Gas turbine jet propulsion plant. ROLLS-ROYCE, Ltd. March 31, 1955 [April 27, 1954], No. 12244/54. Class 110 (3). In a gas turbine engine jetpropulsion plant designed to operate efficiently at a constant value of N/#T 1 , where N is the actual rotational speed and T 1  the engine air intake temperature, in which during low-speed flight the engine speed is reduced, the jet nozzle is provided with means to inject air which has been compressed in the compressor system of the engine into the exhaust gas stream at or near the throat so as to reduce the effective area of the nozzle and thus tend to restore the turbine inlet temperature. An axial flow compressor comprising a stator casing 10 and a rotor 12 feeds air to combustion equipment 15 supplying combustion products to a turbine, comprising a stator 16, nozzle guide vanes 17 and rotor blades 19, driving the compressor through a shaft 14. The turbine exhausts through a jet-propulsion nozzle consisting of a short frusto-conical outer wall 26 forming an extension of the stator 16 and an inner frustoconical wall 27 formed as the periphery of a disc 28 attached to the downstream side of the turbine disc 18. A manifold 29 secured to the wall 26 is supplied with compressed air from the compressor discharge through a manifold 31, conduit 30 and control valve 32. The manifold is connected to the turbine exhaust passage by a ring of orifices 33 situated at the throat of the nozzle. The orifices 33 may be replaced by a circumferential slot or slots. The jets of air passing through the orifices reduce the effective area of the nozzle, the amount of the reduction being determined by the valve 32. In a modification, Fig. 2 (not shown), the invention is described with reference to a convergentdivergent propulsion nozzle suitable for supersonic aircraft speeds. When used in an engine having high and low pressure compressors on independent rotors, the air for reducing the area of the nozzle is taken from the discharge of the high-pressure compressor and used to control the rotational speed of the low-pressure compressor in the manner described in Specification 757,981.

Patent GB-783007-A (GB)
Title: Oil soluble resins
Inventor: HOLLAND STEPHEN DONALD
IPC: C08F240/00
Filed: 1955-04-29
Abstract: Oil-soluble resins are prepared by polymerizing a mixture of a -methyl styrene and a hydrocarbon fraction rich in aromatic hydrocarbons containing olefinic unsaturation, such as styrene, indene and their homologues, and having a boiling range between 150 DEG  and 210 DEG  C.  The hydrocarbon fractions generally contain more than 40 per cent of aliphatic olefines and are obtained by distillation of the liquid products of petroleum cracking processes, or of coal tar.  An alkyl phenol, preferably p-butyl and p-octyl phenols may partially replace the a -methyl styrene, in an amount generally not exceeding 4 parts by volume per 100 of the hydrocarbon fraction to give a product of higher softening-point.  Catalysts such as aluminium trichloride, stannic chloride, boron trifluoride, activated clays and sulphuric and phosphoric acids may be used and dry lime is used to neutralize the reaction mass after polymerization.  In examples, the catalyst is added portionwise and resins of softening-point between 90 DEG  and 130 DEG  C., of molecular weights from 900 to 1200, and soluble in stand oil, are obtained.

Abstract: 310,380. Siemens &. Halske Akt.-Ges. April 24, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Relay devices.-An apparatus for displacing a member in accordance with the movements of the pointer of a measuring instrument comprises means acting periodically to arrest the pointer and means acting preferably at right angles thereto to cause the member to follow the movements of the pointer. In the form shown in Figs. 1 and 2, the pointer 1 is movable between a stirrup 2 and fixed support 3, the stirrup being rocked to press the pointer against the support whereupon actuating members (not shown) open and close the tong arms 4, 5 to adjust the slide 7 arranged between the arms. The slide carries a pen arm 6 to mark a record sheet in accordance with the pointer movements. In a modification, Fig. 3, the tong arms are replaced by spring-controlled arms 14, 15 pivoted to a body member 13 having a slotted arm 11 co-operating with a driving crank pin 10. Movement of the arms is limited in one direction by stops 19, 20. In another modification, Fig. 4, a clockwork or ether motor 22 drives a double-threaded worm 21 having a nut 23 on which is pivoted a double-armed lever 25 co-operating with the pen arm 6 carried on guide bars 26. In another form, Figs. 5 and 6, the stirrup 2 is operated by a roller 27 engaging a cam 28 on a driving-spindle 31 carrying an arm 32. The arm 32 has a pin 34 adapted to cooperate with the pointer 1 and with an arm 36 on a sleeve 35 loose on the spindle 31. The sleeve 35 through gearing 37, 38 adjusts the arm 39 of a regulating resistance in accordance with the movement of the pointer. The drive to the spindle may be through a friction gear or motor which can be braked on the arrest of the arm 32 by the pointer. The member to be adjusted instead of being a recording pen or contact arm may be constituted as a distant optical indicating means.

Abstract: 757,827. Borehole linings. NAAMLOOZE VENNOOTSCHAP WERF GUSTO VORHEEN FIRMA A. F. SMULDERS. April 30,1954 [May 11, 1953], No. 12634/54. Class 85 In the operation of sinking a lining 3, 4, with closed bottom 5, into a borehole 1 filled with, for example, a loaded liquid such as clay suspension 2, the gap between the floating lining and borehole is sealed by an annular sealing ring 10, formed of arcuate members, so that the pressure of the liquid 2 will normally be increased as the lining sinks, the sinking of the lining being controlled through the discharge or supply of liquid 2 to the borehole accompanied, if desired, by the weighting of the lining by liquid ballast. Fig. 1 shows the sealing ring 10 provided in the inner tubbing 11 of the preshaft and in sliding contact with the lining 3, 4. the latter being formed from sheet steel walls confining cement 7 and being continually lengthened at the top by the addition of sections such as 8. Circulation of the clay suspension 2 is affected by pumps 13 which have suction pipes 15, depending to the bottom of the borehole through packed glands in the bottom 5 of the lining, and discharge pipe 16 opening into the space between said borehole and lining; discharge line 17, for draining liquid 2, from the borehole, and liquid supply line 20 are also provided. In a modification, the pipes 15 are disposed between the borehole and lining. Fig. 3 shows a further modification in which a pair of sealing rings 25, 26 are secured to and move with the lining 3, 4, and the lining is fitted with liquid discharge and supply pipes 28 which are extended simultaneously with the building-up of the lining. The annular space 36 above the upper sealing ring 26 is maintained filled with bitumen or a loaded oil, and, after the sinking of the lining has been completed, the space between the rings 25, 26 is plugged with con. crete.

Title: Improvements in or relating to rotary electrical switches
Inventor: DRAGE JAMES JOHN
IPC: H01H1/40
Filed: 1961-04-07
Abstract: 938,106. Retractive switches. BELL PUNCH CO. Ltd. April 3, 1962 [April 7, 1961], No. 12641/61. Class 38 (5). An insulating plate A having conductive areas thereon is urged against fixed contact studs (Figs. 1 and 2, not shown) by a coil spring J, and is rotatable on a fixed spindle F riveted into an insulating base board (not shown) which also carries the fixed contacts. A nylon actuator arm M is secured to the plate A and has a slot M1 accommodating a lug N1 projecting from a key stem N, suitably guided and retractively urged by a spring means, not shown. The arm M is laterally flexible such that any inadvertent side play of stem N when key N2 is depressed is not transmitted to plate A, thereby avoiding intermittent contact as the conductive areas are rotated to bridge the fixed contacts. As additional protection against unwanted operation by vibration the base-board is resiliently mounted on short rubber spindles. The conductive areas on the plate A are formed by an overall copper coating which is etched away to provide electrically-separated segments and subsequently palladium-plated. The fixed contacts comprise silver-graphite studs.
