Title: An improved servo brake
IPC: B60T13/48
Filed: 1926-12-24
Abstract: 279,905. Compagnie Internationale des Freins Automatiques. Dec. 24, 1925, [Convention date]. fluid-pressure.-Brake apparatus for vehicles provided with an internal combustion engine, wherein the brake is applied by a liquid under the pressure of a gas and is released by the. suction of the engine, as described in Specification 226,380, is provided with a vessel interposed between the suction pipe of the engine and the pipe connected to the brake to ensure that sufficient vacuum is available for releasing the brakes even when the accelerator valve of the engine is open. The apparatus shown comprises a differential piston 4<1>, 5<1> connected to the brakes, the part 5<1> of the piston being subject to fluid under pressure in the vessel 6 for applying the brakes. Release of the brakes is effected by connecting the chamber 3 of the piston by the pipe 2 to a vessel 71 which communicates past a non-return valve 72 with the suction pipe 1 of the engine. The valve device for controlling the application and release of the brakes comprises spring closed valves 7, 8 adapted to connect the pipe 2 respectively to the vacuum vessel 71 and to the atmosphere and operated by a lever 74 engaging a sliding member 73 secured to a diaphragm 32 which is subject on one side to atmospheric pressure and on the other side to the vacuum in the chamber 3 and to the pressure of a spring 29. Normally the spring 29 holds open the valve 7 and the brakes are released. To apply the brake the diaphragm 32 is depressed by the pedal lever 24 acting through a spring 75 so as to close the valve 7 and open the valve 8. When the pressure in the chamber 3 acting on the diaphragm 32 has risen sufficiently to overcome the spring 75 the diaphragm moves to permit the closing of the valve 8 and the brakes are thus applied to a degree dependent upon the amount of air admitted by the valve 8. Further depression of the lever 24 re-opens the valve 8 and the braking pressure is thus increased. The brakes may be released step by step in a similar manner bv the return movement of the lever 24, the valve 7 being opened at each stage. According to the Specification as open to inspection under Sect. 91 (3) (a) the brake may be applied by a spring or by a solenoid. This subjectmatter does not appear in the Specification as accepted.

Title: Data transmission systems
IPC: G06F11/08
Filed: 1972-06-22
Abstract: 1372133 Digital transmission; error checking INTERNATIONAL BUSINESS MACHINES CORP 22 June 1972 [26 June 1971] 29188/72 Heading H4P A data transmission system includes two units interconnected by a pair of signal transfer paths one for each direction of transmission, a check character generator in the first unit for generating a check character for signals transmitted in both directions, a single check character transfer path connecting the check generator to a check circuit in the second unit which is responsive to the check character and the signals on both transfer paths to check the correction of the signals transmitted in both directions. As described a plurality of stations A1-AN communicate with a central station B over respective pairs of signal buses C1, CB1; C2, CB2; &c. Each station A includes a selector circuit in the form of gates 40 and 41 which are enabled in response to selector signals on lines 44 from the central station. Assuming central station B requires the transmission of signals from station A2 a selection signal is generated on the line 44 associated with bus CB2. Gate 40 in station A2 is thus enabled and signals are applied from bus 43 to bus C2. Simultaneously control signals are supplied via bus CB2 from the central station to station A2. From these control signals and the parity bit provided on line 46 and associated with the data on bus 43 parity generator circuit, which may consist of a series of cascaded exclusive -OR gates, Fig. 5 (not shown), generates a common parity bit for the signals on both buses C2 and CB2. Gate 41 is opened by the selector signal 44 and the parity bit is transmitted to the central station over line P2. The error checking circuit 52 in the central station receives via OR gates 50 the signals on the bus C2 from unit A2, via OR gate 54 the parity bit on line P2 from unit A2, the control signals transmitted from the central station to station A2 via bus branch 59, and via OR 57 the station select signal applied by the central station to station A2. Circuit 52 checks its inputs for the correct parity, an error signal being supplied over line 58 to flip-flop 60 which is clocked by a timing signal on line 61 where appropriate. Flip-flop 60 is subsequently reset by a signal on line 63. In a further embodiment, Fig. 4 (not shown), only a single parity bit line P is provided between station A1 and the central station. Each station A has additional gating circuits actuated in response to the station select signals on lines 44 so that the parity signal from the selected station A is transmitted over the line P. The arrangement may operate with transmission in only one direction at a time in which case the appropriate parity generating circuit and the check circuit respond only to data on one of the buses Ci, CBi. It is stated that the parity bit transmitted over the lines P may be replaced by a more complex check character, e.g. generated by summing all the digits of a number. The digits being multiplied by their positional values.

Title: Lead-acid batteries
IPC: H01M4/14
Filed: 1968-01-26
Abstract: 1,214,440. Lead-acid batteries. JOSEPH LUCAS (INDUSTRIES) Ltd. 26 Jan., 1968, 29350/70. Divided out of 1,213,471. Heading H1B. A lead acid battery in which the plates are spaced apart by separators and comprise conductive grids supporting active material is characterized in that all the positive plates have a porosity within the active material of 60 cubic mm. per gram or more and the space occupied by pores of more than 1Á m. diameter is less than 20 cubic mm. per gram. The plates may be manufactured by supplying a non- flowable lead-acid battery paste to one face of the plate grid and then subjecting the paste to ultrasonic vibrational energy causing it to flow into the interstices of the grid. In a particular embodiment, the grids, each up to “ inch thick, are pasted in pairs each pair being joined together at their bases and lying flat with their lugs pointing outwards. The grid pairs 21 are transported through the apparatus on conveyer 22, the grids travelling on rails and being drawn along by chain-driven fingers which engage their lugs. The paste is mixed in hopper 23 and extruded from nozzle 39, the continuous strip being cut into sections by rotating wire cutter 41. Ultrasonic oscillator 25 is driven by transducer 54 through velocity transformer 52. Block and pad 57 and 58 are of rubber and bush 59 is of PTFE. The oscillator is cooled by water flowing in at 62 and out at 64. The oscillator dips into the paste on the grid and oscillates at a frequency up to 24 kc/s. and an amplitude of 0À0001-0À01 inch. Its lower surface is inclined at 30-45 degrees to the grids. To paste a pair of grids 4 oscillators are used side by side with PTFE shims in between. Flexible grids are supported by steel bar 24 whilst under the oscillator. The bar is supported on a mounting block (Fig. 3, not shown) which may be heated to 120-200‹ C. by steam passed through it. The support has channels in it to allow some of the paste to pass through the grid to the underside. The gap between the oscillators and support may be closed at the ends by guide plates (82, Fig. 3) which prevent spillage sideways. The upper surface of the pasted plates is smoothed by doctor blade 72 and the places then pass through sensor 73 which activates inverter 74. The-inverted grids are again subjected to oscillation at 28 and smoothed at 75 before entering drying oven 29. Inverter 76 also brushes surplus paste from the edges of the grid pairs before they are separated at 85. In a modification (a) a second paste hopper may be present between inverter 74 and the oscillator 28 to paste the second side of the plate; (b) the conveyers may be of sprocket-type engaging perforations made in special battery grids; and (c) the two oscillators corresponding to each plate may be inclined to give thicker pasting in the middle of the plate.
