Title: Improvements in servo-mechanisms
IPC: F16H61/46
Filed: 1969-11-27
Abstract: 1285930 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 27 Nov 1969 [28 Nov 1968] 57996/69 Heading G3P A servomotor system controlling the delivery of a reversible swash-plate pump 12 through movements of a differential piston 9, 10 seating a valve spool 18, has a bell-crank lever 33 which operatively engages the spool with its end 32, is pivoted to the piston at 34, and has cam surfaces 61-65 co-operating with a slot 42 in a push-rod 41 which is acted upon by the pistons 43, 44 in control cylinder 45, 46 which are selectively pressurized in response to variations in output pressure or flow-rate of the pump. Assuming pump 12 to be feeding motor 16 through line 15, pressure fluid is fed to chamber 59 through ducts 57, 58 and to cylinder 45 through conduit 49. The consequent movement of piston 43 causes slot 42 to engage the upper cam surface 61 to pivot the lever 33 anti-clockwise and thereby slide spool 18 to the left. This movement uncovers groove 22 to permit fluid in cylinder 6 to exhaust through duct 24, drilling 23 and hollow piston-rod 17<SP>1</SP>, and the pressure in chamber 59 moves the differential piston to the left until land 30 again covers groove 22. This movement of the piston is transmitted through a linkage (11) to the pump delivery control mechanism (not shown) to adjust the output pressure. Control cylinder 46 is pressurized to regulate the servomotor in the reverse sense when the pump is delivering through line 14. Piston-rod 17<SP>1</SP> is coupled through a spring link (20) to a lever (21) which sets the datum position, and which may be urged by a spring (66) to the maximum delivery portion. Lever pivot 34 is mounted on a rotatable eccentric to permit the lever 33 to be moved longitudinally to adjust the position of the cam surfaces relative to slot 42, Fig. 5 (not shown) illustrates a modification in which control cylinders (69, 71) are fed with a differential pressure generated across a metering orifice (76) in the pump output line so that lever 33 is moved to maintain a constant flow-rate. Valves (79, 81) in circuit with a pump (77) are provided to effect remote over-riding control of the servomotor by feeding pressure fluid into one or the other of the control cylinders.

Title: Combined Hydraulic System for a Vehicle Transmission Mechanism and Power Steering Gear
IPC: F16H61/14
Filed: 1968-12-06
Abstract: 1,193,930. Motor vehicle hydraulic systems. FORD MOTOR CO. Ltd. 6 Dec., 1968 [28 Dec., 1967], No. 58039/68. Heading B7H. In a motor vehicle hydraulic system for supplying hydraulically-actuated power steering mechanism 30 and an automatic transmission control circuit from a common positive-displacement pump 10, a regulator valve 27 which maintains a regulated pressure level in the control circuit receives fluid directly from the downstream side of the steering mechanism 30, and a valve 16 provides for controlled supply of fluid from the inlet side of the steering mechanism to the regulator valve. The delivery port 12 of the pump 10 communicates with a supply passage 28 for the power steering mechanism through a control orifice 34 and with a supply passage 26 for the regulator valve 27 through a port 22 in the wall of a valve chamber 14. The valve 16 slides in the chamber 14 and is urged by a spring 24 into a position in which the port 22 is blocked. The delivery pressure upstream of the control orifice 34 acts on the valve 16 in opposition to the spring 24, and the pressure downstream of the orifice 34 acts on the valve through a passage 36 to supplement the action of the spring. A spring-loaded check valve relieves excessive pressure downstream of the orifice 34 by passing fluid through a bleed orifice 44 to the port 22. The regulator valve 27 comprises a valve chamber 48 containing a spool having spaced lands 52, 54, 56 and loaded by a spring 58. Opening into the chamber 48 are a port 46 which receives fluid from the passages 26, 72, a port 62 communicating with an exhaust passage 66 which leads to the inlet side of the pump 10, and a feed passage 68 which communicates through a passage 63 with a transmission torque converter. A passage 60 in the spool 50 transmits the pressure at the port 46 to a space above the land 56. A line pressure boost passage 70 is connected to the chamber 48 below the land 52 for applying a control pressure which supplements the loading of the spring 58 to modify the characteristics of the valve. A converter pressure relief valve 64 limits the pressure in the passage 63.

Title: Work piece position control arrangement
IPC: G05B19/29
Filed: 1971-12-21
Abstract: 1400720 Automatic control of position WESTINGHOUSE BRAKE & SIGNAL CO Ltd 19 March 1973 [21 Dec 1971, 8 March 1972] 59468/71 and 10670/72 Heading G3N  An arrangement for controlling the position of a movable tool or workpiece relative to a datum in a metal working press brake, bender or guillotine comprises means for generating signals representing the actual and desired locations of the movable member, means for generating a signal representing the direction of the difference between the previous signals (error) and for generating a coincidence signal and means for moving the movable member to the position at which the coincidence signal occurs. As described the drive motor has a fast speed in both directions and a creep speed in the first direction only. When the initial drive is in the first direction, the motor is reversed at the desired point, but overshoots, is driven at fast speed in the reverse direction at fast speed, is reversed and overshoots and then creeps up to the desired position. When the initial motion is not in the first direction, the motor is reversed directly to the creep speed for final positioning. As shown the movable member is approaching the desired position from "behind". The desired position is manually set into the comparator and the actual position is derived from encoder 5 driven by the drive motor. The comparator coincidence signal is generated on line CC and line BB' is at "1" when the member is "behind" the desired position. A start signal is applied by switch START. As the driven member reaches the desired position (line 2 in Fig. 3) the value on line B changes from 1 to 0. This produces a 0 at the output of inverter 2.1, shuts off the fast forward drive relay RF and enables the fast reverse drive relay RR. The 1 output of inverter 3.2 is applied also to integrator INT, the output of which is connected to NAND gate 9.2. When the coincidence pulse #3 arrives at time 2 gate 9.2 is not enabled since the integrator output #4 is 0 and the slow forward drive relay RC is not operated. At time 3 when the reverse drive moves the member from in front to behind the desired position, the coincidence pulse is gated by the integrator output which is now 1 and actuates the creep drive relay RC. The drive is changed from reverse to forwards and the contacts RCI of the creep relay RC reset the start latch SBL so that no more changes can occur. In a preferred system (Fig. 8) for controlling the position of the back stop of a bending press, up to ten positions can be pre-set into the apparatus. Each desired location is set into one of stores 1-9 and after a bending operation at a particular position the step control is operated either automatically or manually to move the step selector one step and select the next comparator value from the store. The apparatus then moves automatically to this position. The step and the actual position of the member are displayed and the store contents may also be displayed as they are entered.
