Title: Auto-manual electrically-operable controller
IPC: G05B11/36
Filed: 1971-11-02
Abstract: 1360807 Auto/manual controller PRZEMYSLOWY INSTYTUT AUTOMATYKI I POMIAROW 2 Nov 1971 [16 Nov 1970] 50811/71 Heading G3R In an auto/manual controller, smooth switching is effected between a manual control, including an integrator, and an automatic control having a proportional and integral characteristic. As shown, a process variable Xwe is fed to a differential circuit D, and is compared, in summer S1 with a pre-set value X o  to produce an error signal E which is fed to a proportional circuit P and integrator I, the PID circuits forming the auto controller. When the auto mode is selected, ganged contacts Sk1, Sk2, of switch Pr, are connected to contacts A, the output Z of the integrator I being fed through resistor R1 to a further integrator C, which forms part of the manual controller, and which acts as a time delay in the auto selected mode due to feedback resistor R2. A smooth auto to manual changeover is achieved since the controller output V is held by the time delay at its last value before changeover until selection of manual control, when control signals +U or -U are fed directly to integrator C via contacts R of switch Pr. Changeover from manual to auto is also smoothed because the output Z of integrator I, which acts as a time delay in the manual selected mode, follows the controller output V, due to feedback resistors R1 R2. In Fig. 2 (not shown) the integrating, proportional differential circuits and summer S2 are amplifiers with appropriate feedback elements, which may include potentiometers to vary the parameters of the automatic control.

Title: Fluid pressure servomotor

Abstract: 1512409 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 12 Dec 1975 [31 Dec 1974] 51013/75 Heading G3P Electrical signals, which may be dependent on the operating conditions of a vehicle turbine, operate a valve 12 controlling a piston 19, which may be connected to the turbine guide vanes, and provides a feedback position signal to the valve. If the electrical system fails, the valve 12 is biased to a position 68 to connect a space 23 to a pump 65 and a space 26 to a sump 66 causing the piston 19 to move to the right until an auxiliary piston 35 mounted for limited axial movement on the piston 19 abuts an end-face 50. Simultaneously, a space 57 is connected with the sump instead of the pump output so that a telemotor piston 54 can be displaced by a transmitter 14 coupled to the vehicle accelerator. A rod 51 moves with the piston 54 to actuate a control valve 41 forming a moving seat follow-up with the piston 19 which may thus be moved to a limited extent with respect to the piston 35 and allow emergency operation of the guide vanes. In a second embodiment, the telemotor is replaced by a Bowden cable (101), Fig.2 (not shown) and the space 23 is permanently connected with pump pressure through a passage 104 concentric with the cylinder (16) and an electrically operated valve (103) fitted with an inductively operated position transmitter (105).

Abstract: 1410946 Mechanical switches J R HOLLINS 8 Nov 1972 [8 Nov 1971] 51540/72 Heading H1N [Also in Division H2] The electrical system of a vehicle is provided with means whereby when the ignition switch is returned to the OFF position, the lighting control switch is moved to a position wherein all the lights on the vehicle are extinguished. The electrical system of a motor vehicle includes an ignition switch 10 having, in addition to the normal contacts 14, 16, 18, an OFF position terminal 12, together with movable contacts 78, 80 which are connected to a terminal of the vehicle battery 44, the contact 78 being in connection with the OFF terminal 12 when the ignition switch is in the off position. The system further includes a lighting control switch 20 which has a movable contact 38 co-operating with fixed contacts 32, 34, 36 the contact 32 being connected to the battery 44 and the contacts 34, 36 to the various lights on the vehicle.

When the ignition switch 10 is returned to the OFF position current is supplied to the heating coil 82 of the latching member 60 which deflects away from the member 58 thus to release the member which then moves to the off position by means of the spring 52. If desired a further switch 83 may be placed in the circuit of the heating coil 82 whereby to disable the operation of the latching member 60, the switch 83 being interlocked with the switch 20 and having an indicator lamp 90 associated therewith. The system also includes an overload device 40. In other embodiments the latching device consists of a pin retracted by a solenoid which may have a bimetallic switch in the coil circuit and yet again, movement of the contact 38 may be effected by means of a solenoid instead of a spring, the coil of which solenoid may also have a bimetallic switch in series therewith.
