Title: Improvements in and relating to swash plate internal combustion engines
IPC: F02B75/28
Filed: 1965-03-24
Abstract: 1,102,514. Swash-plate mechanisms; pistons. P. MONGITORE. 24 March, 1965 [25 March, 1964; 10 Sept., 1964; 16 Nov., 1964], No. 12479/65. Headings F2K and F2T. [Also in Division F1] Swash - plate mechanisms.- Piston rods 7 are formed integrally with a swash-plate 8, the latter being provided with a sleeve 13 mounted on an inclined sleeve 14, which is keyed to the engine main shaft 22 at 24. Rotation of the swash-plate is prevented by partially meshing gears 17, 18. The sleeve 14 is provided with a flange 15 formed with a balancing weight 25. Between the swash-plate and the flange 15, an internally toothed annular disc 16 rolls on a stationary gear 20 at a lesser speed than the sleeve 14. The disc 16 may be omitted. The flange 15 may be omitted, the axial location of sleeve 13 on sleeve 14 then being effected either by a partspherical extension of the swash-plate, which engages a similarly shaped part of the engine casing. Fig. 9 (not shown), or by a flange, at the end of sleeve 13 remote from the swashplate, which engages a track secured to the cylinder block, Fig. 8 (not shown). Gears 17, 18 may be dispensed with, rotation of the swash-plate then being prevented by forming the latter with outwardly directed fingers which engage in closed tracks formed by recesses in the engine casing, Fig. 7 (not shown). Pistons.-In the modification shown in Fig. 4, the pistons 7a are formed integrally with the connecting rods and are shaped so as to permit tilting during reciprocation. Piston rings, Figs. 5 and 6 (not shown), comprise four annular coaxial and coplanar segments located in a groove in the piston and biased against the cylinder wall by a spring located at the bottom of the groove. The segments may be held together by clamps.

The member 3 is formed with a head 4 and legs 3a, 3b and is held in position by bending pins 12 round a washer 11. The clamp may be released by pinching the sidewalls 2b 1 , 2b 2  together thereby disengaging the pawl from the ratchet. Alternatively Figs. 6, 7, 9, the member 31 is U-shaped, has a band receiving slot 10, and is held in position by a rocking cam 13. The cam is rocked to the position of Fig. 6 to pinch the side walls, from a rest position shown in Fig. 7.

Title: Improvements in or relating to the manufacture of articles of a porous or cellular nature
Inventor: HORSLEY GEOFFREY WINTON
IPC: C04B38/06
Filed: 1965-03-25
Abstract: 1,131,425. Porous refractory oxides. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 4 March, 1966 [25 March, 1965], No. 12705/65. Heading C1A. [Also in Division G6] Porous articles are manufactured by forming a coherent particle incorporating both grains of a refractory or metallic substance and grains of a non-metallic substance which is oxidizable below the melting-point of the refractory substance, sintering and heating in an oxidizing atmosphere e.g. air, CO2, steam or steam and hydrogen to oxidize and remove the non- metallic substance. The refractory substance may be urania, thoria, beryllia, zirconia, alumina, yttria, or silica. The non-metallic substance may be carbon. The particles may be prepared by adding carbon black to an aqueous sol of thoria and urania, the thoria/urania ratio being approximately 10: 1 and carbon/urania plus thoria ratio being 2: 1, dispersing the mixture in a gelling medium, washing and drying the particles, which are then sintered and oxidized as indicated.
Patent GB-1001606-A (GB)
Title: Manufacture of carbon fibres
Inventor: DYNE MICHAEL DAVID CAMERON
IPC: D01F9/16
Filed: 1962-04-03
Abstract: Carbon fibres are produced by heating pure or regenerated cellulose material to between 280 DEG  and 320 DEG  C. for between 1 and 30 minutes in a continuously changing inert atmosphere and then exposing the resulting partially carbonized material to a temperature between 800 DEG  and 1200 DEG  C. in a continuously changing inert atmosphere, the resulting carbon product being then allowed to cool in an inert atmosphere. In an example, a loose roll of viscose rayon cloth is heated slowly over two hours to 300 DEG  C. at which temperature it is maintained for 10 minutes; the oven is then slowly heated to 1000 DEG  C.  During the whole process so far, N2 is flushed through the oven.  After a few minutes the material is allowed to cool in an inert atmosphere.  It has the form of a mass of smooth fibres of pure electrically conducting carbon, having the shape and flexibility of the original roll of cloth.  The process may be carried out continuously in a tunnel furnace. The cloth may be thrust repeatedly into and out of a region of a furnace maintained at between 900 DEG  and 1000 DEG  C.  The carbon fibres are non-crystalline and resemble, in form, a glass. A more crystalline structure is achieved by heating to 2000 DEG  C. at which temperature the fibres crystallize to a graphite form. Other cellulose materials that may be used are nitrate or cuprammonium process rayon or cotton wool. Specifications 998,089 and 1,001,607 are referred to.

Inventor: SMEDLEY FREDERICK EDWARD SAMUE
IPC: F02C7/236
Filed: 1952-05-20
Abstract: 735,874. Centrifugal pumps; gas turbine engines. ROLLS-ROYCE, Ltd. May 14, 1953 [May 20, 1952], No. 12785/52. Classes 110 (1) and 110 (3). A gas turbine fuel supply system comprising a main fuel pump and at least one other pump, has fuel bled from the discharge of the main pump and led to an hydraulic motor driving the other pump. The second pump may be a booster pump for the main pump, a pump for supplying fuel to the exhaust pipe of a jet propulsion engine or to a reheat chamber between two turbines in a compound gas turbine engine or a pump supplying liquid for injection into the intake of the compressor. Fuel is supplied to the combustion equipment 11 of a gas turbine jet propulsion engine by an engine-driven main fuel pump 19 through a fuel line 17, throttle valve 18, manifold 16 and burners 15. The pump 19 may be of the positive-displacement fixed capacity or positive-displacement variable capacity or of the centrifugal kind. Fuel is supplied to the inlet 19 from the fuel tank 21 by a booster pump 22 driven by an hydraulic motor 23 supplied with working fluid from the fuel line 17. In a modification, additional fuel is burnt in the exhaust pipe 13. This fuel is supplied by a pump also driven by an hydraulic motor supplied with working fluid from the fuel line 17. This pump may draw fuel either direct from the tank 21 or from the discharge of the pump 22. In the arrangement shown in Fig. 4 the booster pump 22 is driven by an electric motor 26 and the pump 42 which supplies a mixture of water and methanol to the intake of the compressor 10 through injectors 45 is driven by an hydraulic motor 46 supplied with working fluid by the pipe line 17. Modifications of the arrangement shown in Fig. 1 in which the fuel tank is cooled or the fuel leaving the hydraulic motor is cooled in a heat exchanger before entering the tank are described. The working fluid for the hydraulic motor may be taken off from the discharge volute of the pump 19 and may be returned to the suction side of the pump. The hydraulic motor may be of the turbine or Pelton wheel kind or may be of the positive displacement type such as a gear or sliding vane motor. Specification 735,913 is referred to.

The proportions of the levers is such that the window is balanced in the two extreme positions. If it is desired to balance the window in all positions, each lever i is replaced by a cam acting on a second cam to which the links h are pivoted.
