Title: Control Valve with Lock Out Element.
IPC: F15B13/01
Filed: 1967-08-22
Abstract: 1,171,840. Vehicle power steering valves. NEW YORK AIR BRAKE CO. 22 Aug., 1967 [27 Oct., 1966], No. 38618/67. Heading B7H. A two-position lock valve 43 with means 61 for damping movement from its open position to its closed position is provided in a control valve 10 comprising inlet and exhaust passages, first and second delivery passages 44, 46, first and second motor passages 39, 41, an open-centre metering valve 22 and actuating means responsive to movement of the metering valve 22 for shifting the lock valve to its closed position when the metering valve is moved to its neutral position (as shown) and to its open position when the metering valve is moved from its neutral position in either direction. The spool of the valve 22 is provided with flats 31, 32, 33, 34 so that the control orifices A to D provide a throughflow proportional to movement of the spool from the neutral position which is adjustable through the centralizing spring device 35. The damping valve 61 which is movable to the left in its bore in the lock valve spool to permit relatively free passage of hydraulic pressure fluid from the inlet chamber 19 to a chamber 37 at the left-hand end of the lock valve spool, permits only restricted flow in the opposite direction, when it is seated by a biasing spring, through a bore 62 partly obstructed by a spring ring 63. In the metering valve neutral position the pressure of the inlet chamber 19, communicated through passages 45, 59, 58 and the damping valve 61 to the chamber 37, is insufficient to move the lock valve spool against the biasing spring 57 and the exhaust fluid pressure in the chamber 36a acting on the right-hand end of the valve spool, but when the metering valve spool is moved from its neutral position the increased inlet chamber pressure communicated to the chamber 37 is sufficient to move the lock valve to the right when the delivery passages 44, 46 are connected through the annuli 47, 49 with the respective motor passages 39, 41. When the metering valve spool is returned to or passed through the neutral position by a driver or the follow-up linkage 15, due to the restriction in the damping valve, the lock valve 43 is not immediately closed thereby reducing steering linkage shook loads.

Title: Improvements in or relating to an internal combustion engine change forming device
Inventor: ARMSTRONG JAMES FRED
IPC: F02M69/22
Filed: 1957-12-23
Abstract: 857,423. Spray carburetters. ACF INDUSTRIES Inc. Dec. 23, 1957, No. 39857/57. Class 7(3). In a fuel injection system having injection valves 29 carried by diaphragms 28 and controlled by the pressure of the metered fuel supplied to chamber 30 and by the constant pressure in a datum system 58 supplied to chambers 571, a pressure absorbing device 126 is actuated by the throttle valve 50 to absorb the fuel displaced from the chambers 571 when an increased fuel supply increases the opening of the valves 29. The fuel is delivered to a chamber A at constant pressure by a pump 20 and is metered by needles 23 controlled through a magnetic clutch 35 by a valve 37 which measures the air flow. The valve 37 is actuated by a diaphragm 40 subjected to suction at points 44, 45, on opposite sides of the valve, the suction in the chamber 43 being modified at part throttle openings by a bleed valve 212 controlled by the suction downstream of the throttle valve 50. At part throttle openings the valve 212 is opened to reduce the suction in chamber 43 and produce a leaner mixture, the mixture ratio being varied, as the throttle valve 50 opens, by a plate 37a on valve 37 which co-operates with the inlets 203 of the bleed passage 205. The fuel supply at cold starting is increased by a thermostat 102, combined with a suction-actuated piston 105, which acts on an arm 100 on the shaft 36 of the valve 37 to move the valve 37 and metering needles 33 in the opening direction. The datum pressure in pipe 58 is maintained constant by a valve 75 at its upstream end and by an outlet orifice 61 the pressure below which is maintained constant by a valve 167 actuated by a diaphragm 165. When the starter switch S is closed a solenoid 173 is energized to open valve 167, which reduces the datum pressure to allow the valves 29 to open and provide a rich starting mixture. A normally closed valve 303 in a by-pass around the valve 75 is opened during over-running by opening of a suction actuated switch 253 which de-energizes a solenoid in the circuit 298, increasing the pressure in the datum circuit 58 to equal that in the metering circuit 24 so that valves 29 close and cut off the fuel supply. Opening of the ignition switch 197 also breaks the circuit 298 and cuts off the fuel supply. The fuel supply is also cut off for deflooding during starting by de-energization of a second solenoid associated with valve 303 when the throttle valve is opened wide during cranking, which opens a switch TS. The absorbing device 126 is actuated from the throttle shaft 51 through a resilient connection 30 to a lever 311 which is connected to a diaphragm 127. Specifications 807,519 and 839.994 are referred to.

Abstract: 918,940. Ratchet gearing. GRETAG A.G. Nov. 10, 1961 [Nov. 12, 1960], No. 40364/61. Class 80 (3). [Also in Group XIX] In a step-by-step mechanism in which forward and reverse rotations are produced by separate electromagnetically operated pawl-andratchet mechanisms, a control member is movable to two discrete positions to render the non-driving pawl inoperative and the pawls are arranged that energization of the magnet moves the pawl through an idle stroke and de-energization allows an armature spring to produce a rotation of one tooth of the ratchet-wheel. In a stepping mechanism in which a shaft 23, carrying indicating, 26, and printing, 27, figure rollers, is rotated in either direction, the two rotations are produced by similar oppositehanded electromagnets 1F and 1B, the armatures 6F of which operate arms 11F carrying pawls 13F co-operating with forward and backward ratchet-wheels 16F and 16B, respectively, on the shaft 23. A common control member 53 freely mounted on the shaft 23 has an attachment 52F contacted by an extension 51F of the armature arm 11F to move a cam 54B into the path of the pawl 13B to hold it from engagement when the forward magnet 1F is operating, a similar cam 54F restraining the pawl 13F when magnet 1B is energized. Shock-absorbing stops 18F, 20F limit movement of the pawl 13F under the action of the armature spring 12F and magnet 1F, respectively, to one tooth stroke and ensure full tooth engagement of the pawl except when held from engagement by the cam 54F. A fivelobe cam 28, on the shaft 23, co-operates with five pairs of switch contacts 31I, 31II to provide for zeroizing, tens carry-over and pulse counting. A number of the stepping mechanisms may be placed side-by-side and the digits on the rollers 27 used for printing through carbon paper 45 (Fig. 10) on depression of a printing hammer 46. In modifications, the casing may comprise side plates held apart by distance pieces or may be hermetically sealed and filled with an inert gas.
