Title: Internal combustion engines
IPC: F02B25/14
Filed: 1972-01-17
Abstract: 1383994 Combustion chambers A MOIROUX 17 Jan 1972 [18 Jan 1971 13 Jan 1972] 2053/72 Heading F1B I.C. engine comprises at least one separate combustion chamber connected to at least one compression and expansion chamber for the engine fluid and a distribution member for controlling communication between the compression and expansion chamber and the combustion chamber. Two stroke reciprocating piston engine has inlet and outlet valves 4 and 5 (only one of which is shown) and a further valve 6 which allows communication between a combustion chamber 7 and the cylinder space 1. All the valves are controlled by a cam shaft 8, and push rod and rocker 9. The combustion chamber has a cooling jacket and contains a refractory steel sleeve 10 which guides the air to sweep past the tip of a fuel injector 11. In a four-stroke rotary engine, Fig. 2, combustion occurs in the chamber 22 and the valve 18 is opened to allow the gases to act on the rotor 12. In the two-stroke engine the cylinder is scavenged by air from a rotating blower, the valves 4 and 5 close and the air in the cylinder is compressed during the upward stroke of the piston. The valve 6 is opened to allow air to flow into the combustion chamber when the piston is nearing the top of its stroke, combustion occurs and the expanding gases drive the piston down, the valve 6 closing when the expansion has continued to a point such that the pressure in the combustion chamber is equal to the pressure which existed at the beginning of the cycle. In the rotary engine a half revolution of the engine is used for expelling the burnt gases and drawing in a fresh charge.  The communicating valve 6 or 18 may be shaped in the region immediately behind the valve head to act as a deflector to direct air into the combustion chamber and may open to a lesser degree during this admission of air to the chamber than during the passage of combustion gases from the chamber to the cylinder. In a modification, Fig. 10 (not shown) the seat for the valve 6 or 18 has tangential slots formed in it and the combustion chamber is generally spherical and co-axial with the valve, so that the air is swirled as it enters the chamber. The valve lift for the passage of air to the chamber is less than that for the passage of burnt gases to the cylinder.

Title: Improvements in variable-speed gears
IPC: F16H47/06
Filed: 1938-01-21
Abstract: 509,839. Hydraulic power transmitters. VOITH, W., VOITH, H., and VOITH, H., (trading as VOITH, J. M., [Firm of]). Jan. 21, 1938. No. 2100. Convention date, Jan. 21, 1937. [Class 69 (ii)] Variable-speed gear for vehicles, the lowerspeed stage of'which includes a constantly filled turbo converter, the guide ring of which is adapted to be held fast by a brake which is released when a mechanical connection is engaged between the driving and the driven shafts of the gear for the higher-speed stage, is characterised in that the mechanical connection between the driving shaft which is connected to the pump rotor and the driven shaft which is connected to the turbine rotor has the form of a jaw clutch which is adapted to resist engagement when not in synchronism. The engine shaft 1, Fig. 1, drives the shaft 2 carrying the impeller 3 of the torque convertor and provided with gear teeth 8; the turbine 4 drives a shaft 6 on which is splined a wheel having gear teeth 7. The teeth 7, 8 are backed off as shown in Fig. 3. The wheel carrying the teeth 7 is movable axially by a lever 9 acting through spring 10 and lever 9a. When the lever 9 is moved from its converter-drive position shown over to the direct-drive position, a brake band 11 restraining the reaction member 5 against rotation is released, and the teeth 7 are urged by the spring 10 into contact with teeth 8, but engagement does not take place since teeth 8 are over-running teeth 7. To effect engagement, the driving shaft 2 is temporarily decelerated; this may be effected, automatically as a consequence of movement of the lever 9, by a control connection arranged to over-ride the ordinary throttle control means and to shut the throttle when the spring 10 is expanded; this over-riding connection may include an electrical control circuit comprising a brush and a contact segment mounted respectively on the levers 9, 9a. When the lever is moved back to its original position the brake band 11 is applied; disengagement of the teeth is prevented by the loading thereon, but deceleration of the shaft 2 by the over-riding throttle control permits the spring 10 to disengage the teeth. The gear may be followed by a planetary gear 14 capable of being changed while running to interrupt or reverse the drive to the road wheels 16. The reversing gear may be of a type which is incapable of being changed while running; a clutch is then interposed between the engine and driving shafts ; the clutch is so connected with the gear that as soon as the clutch is disengaged the lever 9 is forced into the converter drive position, thus rendering impossible starting on direct drive. The clutch, the lever 9 and the brake 11 may be actuated manually or automatically, by vacuum or otherwise; a multi-ratio tooth wheel gear capable of being changed while running may be disposed behind the gear.

Abstract: 874,998. Disc brakes. DUNLOP RUBBER CO. Ltd. Jan. 21, 1960 [Jan. 23, 1959], No. 2502/59. Class 103 (1). In a disc brake comprising angularly moving pressure plates 12 pivotally secured at 15 to a non-rotatable support 1 and having a pad of friction material 13 pivotally secured to each pressure plate 12 to frictionally engage a rotatable disc 2, means (7) is provided to effect frictional engagement and resilient and deformable members 17 comprising initially straight metal wires or rods which engage at each end with anchor pins 16 and pivots 15 of fixed support 1 and which engage between their ends with angularly movable pressure plates 12, the members 17 being deformed by angular movement of the pressure plates 12 towards the disc on application of the brake and being sufficiently resilient to separate the friction pads from the disc when the brake is disengaged. As the brake pads gradually wear during service the pressure plates gradually advance towards the disc and application of the brake thus progressively deforms the resilient wire members 17 as angular movement of the pressure plates gradually increases at every brake application. The inherent resilience of the resilient wire members is sufficient to retract the brake pressure plates a predetermined distance away from the disc when the braking pressure is removed, irrespective of wear of the pads. When fresh pad assemblies are assembled to the brake to replace worn pad assemblies the members may be straightened for re-use or may be simply replaced.

Title: Improvements in or relating to insulated electric terminals for leading electric conductors through metal surfaces and containers for electric components
IPC: H01G2/10
Filed: 1944-02-11
Abstract: 577,219. Mounting terminals ; metal-glass seals. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and POWERS, S. J. Feb. 11, 1944, No. 2537. [Classes 36 and 38 (i)] [Also in Group XXIII] In an insulated electrical terminal, a tubular member of fusible insulating material is sealed through an aperture in a metal plate and has a conductor member passing co-axially therethrough, sealed to the inner surface thereof at a constriction formed in the neighbourhood of the aperture in the plate. A long electrical leakage path is thus provided between the conductor and one side of the metal plate. The latter may form part of a hermetically sealed vessel or cable head for multiconductor cable or a container for an electrical element. Fig. 1 shows one embodiment in which the conductor is a copper rod 12 having a ferrule 13 on its upper end to which is soldered a cap 7 so as to shroud the glass tube 3 of lime-soda glass fused to the copper plate 1. In a modification, Fig. 2, a long leakage path is provided on both sides of the plate, by sealing a second glass tube 4 thereto, co-axially with the tube 3, the conductor comprising a metal tube 5, the end of which is spun over to form a flange 6 for soldering to the cap 7. A wire 9 may pass through a hole in the cap, afterwards sealed by solder, and through the tube 5. The leakage path may be increased by providing further glass tubes of larger diameter co-axially surrounding the existing tubes and sealed thereto adjacent the plate, the cap 7 being preferably increased in diameter to shroud the outer tube. The plate 1 and central conductor may be of different metals, the tubular insulator being composed of two different types of glass suitable for sealing respectively to the two metals. For example, the plate may be of copper with a preliminary button of lead glass sealed in the aperture therein, the conductor being of chrome iron sealed in an insulator of lime-soda glass, the two glasses then being sealed together to form a composite member.
