Abstract: 1,036,860. Gas turbine engines. ROLLSROYCE Ltd. Dec. 30, 1964, No. 52886/64. Heading F1G. [Also in Division F2] In a bearing device a shaft 14 of a gas turbine engine rotates in a bush 15 having a longitudinally arcuate outer surface 16 abutting a longitudinally arcuate inner surface 17 of a fixed housing 18, the radius of curvature of the said outer surface 16 being less than that of the said inner surface 17, so that the bush may rock when the shaft tilts. Oil is supplied to the inner surface of bush 15 via duct 23 in the housing and drilling 24 in bobbin 25. The bobbin has flanges 26, 27 in apertures in the housing and bush, diametrically opposed flats 28 to allow relative movement of bush and housing, and rectangular boss 30 to prevent its rotation. The bush bears on annular springs 21, 22 during tilting of shaft and bush, and the springs also tilt the bush when the shaft is not tilted, to reduce oil loss. The bush may be assymetrically curved and may contain a roller bearing. The bearing is applied to a shaft of a gas turbine jet engine used as a "tip jet" on the end of a helicopter rotor blade.

Abstract: 1496147 Reciprocating pumps J EBERSPACHER 9 Dec 1974 53143/74 Heading F1A A pump, especially for the injection of fuel to combustion chambers, comprises a cylinder 2 divided by a reciprocable piston 1 into a suction space 6 and a delivery space 5, the spaces being inter-connected by a constricted passage 7 whereby during contraction of the space 6 fluid previously admitted thereto through a non-return suction valve 3 is transferred to the space 5 through the passage 7. Delivery of fluid past a non-return valve 4 occurs when the space 6 is expanding since the constricted passage 7 inhibits return flow to the space 6. The piston may be reciprocated by an electro-magnet, Fig. 3 (not shown) or a piston rod passing through the space 5. If the piston is of sufficient dimensions, delivery also occurs during contraction of the space 6. The passage 7 may be in the piston or be constituted by the clearance between the piston 1 and its cylinder 2.

The composition can be made by granulating the copolymer, coating the granules with the polysiloxane, transporting the granules into a pressure zone sufficient to cause the granules to pass through the remainder of the process, melting and shearing the mixture. By separating the two extrusion functions of transportation and mixing, the oily nature of the additive does not inhibit full mixing.

Abstract: 1,160,709. Gas turbine combustion chambers. JOSEPH LUCAS (INDUSTRIES) Ltd. Dec. 8, 1966, No. 55005/66. Heading F1L. A gas turbine engine flame tube formed by annular walls 10, 11 is axially movable relative to a fixed annular member 25 carrying fuel nozzles 26 so as to vary the size of the apertures defined between the member 25 and walls 10, 11 and thus to vary the quantity of primary combustion air flowing therethrough. At the same time the quantity of cooling air flowing to the spaces between walls 10, 11 and casings 12, 13, respectively, is varied. Some of the cooling air flows through outlets 15, 16 to the turbine. The axial movement of the flame tube is effected by a mechanism including a shaft 23 rotating a gear 21 threaded on a screw 20 attached to the flame tube by an arm 19, the gear 21 engaging also an outer ring gear 22 supported on rollers 22a. The ring gear meshes with further gears 21 on screws 20 spaced around the flame tube.

The downstream ends of the walls 10, 11 slidably engage casings 12, 13 through shoes 18. Movement of the flame tube may be controlled manually or in response to the fuel supplied. The construction is applicable also to angularly spaced cylindrical flame tubes mounted within a common annular casing or within individual casings.

In a battery of standard cells in which the cells have heating means for maintaining them at a predetermined temperature, the cells are contained in an inner box 13 within an intermediate box 15 enclosed in an outer casing 17, and the length of the part of each of the leads 18, 19 joining the cells to the external terminals 20, 21 associated with the wall of each box is greater than the thickness of these walls. This arrangement enables a part of each lead between its cell and the intermediate box to be at the temperature of the inner box; and a part of each lead between the inner box and its external terminal to be at the temperature of the intermediate box. As shown in Fig. 2, the inner and intermediate boxes 13, 15 are made of aluminium and are separated by insulating material 14. Another layer 16 of insulating material separates the intermediate box 15 and outer casing 17. Each cell is connected to a pair of external terminals 20, 21 by a pair of leads 18, 19 which are wire coils each enclosed in an insulating sheath. Each lead passes through a channel 23, down a channel 22 between the inner and intermediate boxes and up a channel 24.
