Title: Improvements in or relating to hydraulic power transmission systems
IPC: F04C11/00
Filed: 1959-02-20
Abstract: 865,625. Hydraulic transmission of power. PAYNE, R. Feb. 20, 1959, No. 5932/59. Addition to 832,776. Class 69 (2). [Also in Group XXVI] An hydraulic transmission comprises a pump and motor having bladed rotors 87 which intermesh with recesses 89 in rotary baffles 90, the pump and/or motor being provided with by-pass means 204 to pass fluid from the leading side 210 of the blades to the opposite side 209 as the blades pass through the recesses in the baffle. The pump is partitioned into a plurality of sections each consisting of a rotor having blades 88 which are of gear-tooth shape to provide a close fit with the recesses 89 during the passage of the blades. As a blade enters the recess of a baffle, which is driven from the rotor by gearing 200, 201, fluid displaced from the leading side 210 of the blade passes through the by-pass passage 204 and a duct 206 to a passage between the housing 202 for the baffle and an inner part 203 of the casing 80. As the blade leaves the recess, fluid passes through a duct 205 and the passage 204 to the rear side 209 of the blade. The arrangement provides a leak-proof seal between the low and high-pressure chambers 101, 102, while permitting the baffle to spin freely. A chamber 103 formed between the minor part 203 and casing 80 provides a by-pass chamber between the chambers 101, 102 and is controlled by valves 98, 99, the former being operated by a cam 106. The various sections of the pump may thus be made operative for a particular gear ratio to be selected as is described in the parent Specification. The motor may be provided with a by-pass valve to enable it to be run free of the pump. A seal 217, Fig. 6, consisting of a ring of square or other section, may be provided in a groove in the rotor and be spring-urged against the wall of the rotor housing. The temperature of the fluid in the transmission may be controlled by maintaining a predetermined pressure in the return line of the system by an adjustable, spring- loaded relief valve disposed between the supply tank and a radiator, a small pump or reducing valve maintaining the supply at this pressure. A governor and pressure-operated valves may be employed to control the system automatically.

Abstract: 711,827. Casting-machines; making electric battery plates. LUCAS (INDUSTRIES), Ltd., J. Feb. 25, 1953 [March 10, 1952], No. 6139/52. Classes 83 (1), 83 (2) and 83 (4) An automatic metal-casting machine, more particularly for casting the plate grids of electric storage batteries comprises the combination with a body part of a mould, a trimming means, and a waste ejector all mounted at successive positions on the body, and an endless conveyer movable between the said positions, the conveyer having combined therewith means to be embedded in the casting and to anchor the casting to the conveyer. The body 2, Fig. 1, carries the mould 3, 4, of which the part 3 is closed at the appropriate time by a rod 8 operated through cam mechanism from a shaft 13 driven by a sprocket chain 21. The latter is rotated by an electric motor 14 which also drives, through a gear box 17, a driving sprocket 75 for the conveyer belt 67. The sprocket 75 transmits motion through an automatic one-revolution clutch to the conveyer so that it moves intermittently in timed relation with the casting &c. operations. A crank disc 24 is also driven intermittently to move, through a connecting rod 25, a ladle 23 for pouring metal into the mould. Fangs 95 project down from transverse bars connecting the two sides of the conveyer chain at spaced intervals around its length. These fangs depend into the mould cavity so that the articles being cast, such as the plate grids of storage batteries 96, Fig. 6, are cast thereon. When the mould is opened the conveyer thus moves the cast part to the next station at which is a trimming punch and die 32, 33. Shearing.-The punch 33 is operated by an eccentric 39 driven intermittently through a onerevolution clutch associated with a shaft 40 from a further electric motor 42, the operations being timed by the cam-shaft 13 driven by the first motor 14. The plate grids are severed from a surrounding waste portion, which is held by a spring-loaded frame 100, and pushed out through the stationary die 34. The conveyer is held stationary during the punching operation by a fork 97a carried by the punch 33. The waste remains attached to the fangs but is removed therefrom at the next station by an ejector 64 opposite the mould-closing device and operated by the same cam-shaft 13. The movable part of the mould and the trimming device may be operated by fluid-pressure devices in lieu of the cam operation.
