Abstract: 1,105,950. Power assisted steering; telemotor steering. INTERNATIONAL HARVESTER CO. 26 Nov., 1965 [21 Dec., 1964], No. 50315/65. Heading B7H. In a power-assisted steering system having a power-driven pump 12 supplying pressure fluid and a manual control pump 20 which directs, and adds to the pressure of, the pump output to a reversible steering or other servomotor 18, a spool valve 16 is provided with a third chamber 46 (or 48), receiving pump pressure fluid, between a first chamber 50 (52), receiving working pressure fluid from the control pump 20, and a second chamber 40 (or 42), receiving return pressure fluid, to reduce fluid leakage between the first and second chambers. To steer a vehicle, for example to the right, the pump 20 is rotated clockwise by a steering wheel 22 producing a pressure differential between the valve end chambers 120 and 124 to displace the valve spool 34 to the right (Fig. 2, not shown) against the force of the centring spring 70. Pump pressure fluid then flows through inlet 54, valve spool bores 132 and 128 and a line 78 to the control pump 20 further rotation of which increases the fluid pressure to a working pressure and directs the fluid through a line 76, valve chambers 120 and 50 and a line 84 to the servomotor to displace the servomotor piston 74. Fluid is displaced from the servomotor at a return pressure through a line 86, the valve chamber 52, passage 94 and 44 and an outlet passage 88 to a reservoir 10. Fluid is supplied to the third chamber 46 from the pump 12 through valve passages 54, 53 and 92. Telemotor.-Should the pump fail, the system acts as a telemotor and the pump 20 displaces the valve spool 34 and draws fluid from the reservoir through a check valve 102 and directs it to one or other side of the servomotor 18, exhaust fluid from which returns to the reservoir.

Patent GB-506225-A (GB)
Abstract: 506,225. Fluid-pressure servomotor-control systems; liquid-pressure engines SPERRY GYROSCOPE CO., Inc. May 27, 1938, No. 15871. Convention date, May 29 1937. [Classes 69 (ii) and 135] A control system for aircraft control surfaces provided with auxiliary control surfaces such as " trim tabs " has a servomotor for operating the auxiliary surfaces controlled by the tension in the cables operating the main control surface. The main control surface is operated by cables 6, 7 connected to a hand lever 5 and also to the power device of an automatic pilot (not shown). The auxiliary control surface 3 is pivoted at 4 to the main surface and is coupled by a cable 69 with a pulley 68 adapted to be rotated by a hand wheel 5<1> or a servomotor 21 acting through a pulley 65 and cable 67. The tension-sensitive devices which are fitted to each of the cables 6, 7 comprise three pullies 9, 14, 15 of which the pullies 14, 15 arranged below the cable are carried by brackets 16, 16<1> secured to a valve casing 13 while the pulley 9 arranged above the cable is secured to a spring- loaded piston valve 12 mounted in the valve casing. An increase in cable tension lifts the valve member causing grooves 23, 23<1> to connect pipes 20, 22 leading to the servomotor with pipes 24, 26 connected respectively with a motive fluid pump 25 and a sump 27, so causing the servomotor to operate in the direetion necessary to adjust the auxiliary surface to the sense required to reduce the cable tension. The tension-sensitive devices on the two cables operate to rotate the servomotor in opposite directions. The speed of operation of the power device is controlled by a needle valve 28 actuated by a hand-operated screw geared to an indicator. The power device comprises a rotating cylinder-block housing four equally spaced pistons coupled by connecting rods 71 with a stationary eccentric shaft. The cylinderblock has trunnions mounted in ball bearings 35, 351 and is connected by a universal coupling 66 with the pulley 65. The side walls of each cylinder have ports 62, 62<1> adapted to cooperate with pairs of semicircular grooves 37, 37<1>, 38, 381 in the casing connected to the supply and exhaust conduits. The supply and exhaust grooves are connected by two byepass conduits, one controlled by a valve 43 adapted to be manually actuated from a remote point by a cable 45 and pulley 42, the other housing a double-acting relief valve 53 of the kind described in Specification 455,673 and U.S.A. Specification 2,069,214. Passages connecting the crank-case with the supply and exhaust conduits are fitted with spring-loaded looseball relief valves adapted to relieve excess pressure in the crank-case.

An apparatus for filling bags 2 with compacted rubbish comprises a rotatable carrier 1 arranged to reciprocate a bag, between a shoot 3 from which rubbish drops into a bag A and a compacting station 3a where the rubbish is compressed by a reciprocating plunger, until the bag is full. The plunger (Fig. 2) has a rack engaging a gear (21) driven by a motor. The carrier 1 is rotated by reversible motor 10 controlled by a photo-electric relay 6, a limit switch 12 actuated by a cam 14 on the carrier 1 and a time-delay switch (26) associated with the plunger. Rubbish collected in the bag A interrupts a light beam 4 causing the photoelectric relay 6 to activate the motor 10 which moves the bag A to the compacting station 3a, the limit switch 12 maintaining the motor 10 in operation until the bag A arrives at the compacting station. The plunger is then activated and if its upper end descends below a rod (25) actuating the time-delay switch (26), the latter is activated and the bag is returned to the shoot 3 for a further fill. When the plunger does not descend below the rod (25) the carrier is rotated under an impulse produced by the photo-electric relay is response to the filling of bag B to move bag A to a position 3b and bag B to the compacting station 3a.

In information retrieval apparatus, a member has translucent and opaque sections through which light is transmitted as a binary code to a number of photo-cells one of which serves to control the light source so that the output of that cell is maintained constant. As shown, light from a lamp 10 passes down a light guide 12 to illuminate a member 13 which carries binary information constituted by translucent and opaque portions such as 14, 15. A number of photo-cells 16 is arranged so that each is adjacent to one portion of member 13 and the photo-cell outputs are transmitted through amplifiers 17 to an information processor 18. A portion of the light passing through one translucent portion determined by a diaphragm 23 or, alternatively, by an attenuator or filter, falls on a control photo-cell 19 the amplified output of which is compared with a reference signal 22 so that any difference is effective to control the energization of lamp 10 and thus maintain the output of photo-cell 19 constant. If member 13 is moving, the proportion of light falling on the control photo-cell may be determined by alternate translucent and opaque portions an integral number of which are viewed by the photo-. cell.
