Title: Monitoring Device for Servo System
IPC: G05D1/00
Filed: 1966-09-28
Abstract: 1,164,511. Alarm systems. KOLLSMAN INSTRUMENT CORP. 28 Sept., 1966 [28 Oct., 1965], No. 43210/66. Heading G4N. A monitoring device for a servo system comprises a monitoring amplifier 20 coupled to the servo error signal and feeding a first relay 21, arranged to operate an indicator 38 and to energize a further relay 22a, contacts of which isolate the error signal from the monitoring amplifier. In the altimeter shown, the output of an aneroid 10 is compared with the setting of an indicator 12, the resulting error signal being amplified at 18 and used to drive a motor 19 which corrects the error. In the event of a fault in the system the error signal may be sufficiently large to operate a relay 21 having a three-second time delay capacitor 33. Energization of relay 21 releases a further relay 32 after a further three-second time delay imposed by capacitor 34. The contacts of relay 32 disconnect a solenoid 37 controlling an indicator flag 38 and disconnect the servomotor 19. Relay 22a is also energized at this stage, contacts of which shortcircuit the input to the monitoring amplifier 20 and restore normal operation. If the fault is still apparent, this sequence of operations continues, until relay 31a is manually energized, to inhibit the system.

Title: Self-steering axles for road vehicles
IPC: B62D13/06
Filed: 1966-09-29
Abstract: 1,110,307. Self-steering wheels. K. W. VIGUS. 6 March, 1967 [29 Sept., 1966], No. 43469/66. Heading B7D. In a vehicle having a pair of self-steering wheels 2 means are provided for reversing the trail 12 of the wheels when the direction of motion of the vehicle is reversed. In Fig. 1 an axle 1, carrying at its ends the self-steering wheels, is rotatable mounted in bearings connected to springing 8. A lever 4 rigid with the axle is pivoted to a piston-rod of a piston and cylinder arrangement 5, the cylinder being pivoted to a clamp 14. When the direction of the vehicle is reversed hydraulic fluid is supplied to or withdrawn from the cylinder, shortening the exposed length of the piston-rod and thereby rotating the axle so that the king- pin axis 11 cuts the ground a distance 12 from the opposite side of axis 10. The fluid may be controlled by valves operatively connected to the vehicle gear-box and supplied by a vehicle engine operated pump. In the case of independent suspension the king-pin or equivalent axes are rotated by altering the lengths of suspension linkages. In the embodiment of Figs. 5 and 6 the piston and cylinder arrangement may be operated pneumatically with the axle positively located mechanically. The pistonrod is connected to the axle by a socket joint 19, a system of levers 18 pivotable about a pin 17 passing through the axle, rods 21, 22 and a plate 26 rigid with the axle. The rods are pivoted to the levers 18 via clevis blocks 20 from which also extend rods 23, 24 to similar plates 26, 25 at the opposite end of the axle. As illustrated, rod 22 passes through plate 26 into a hole 27 in the plate 25 rigid with axle bearing 3. To reverse the trail the piston-rod is shortened, causing the lever 18 to pivot about pin 17 and withdrawing rod 22 from hole 27. Further pivoting is prevented by the end of rod 21 contacting plate 25 but continued shortening of the piston-rod causes the axle to rotate until plate 26 is stopped by upper block 29. Rod 21 is now aligned with hole 28 in plate 25 and may enter it thereby locking the axle in its new position.

Title: Control device for electric storage heaters
IPC: G05D23/19
Filed: 1975-10-23
Abstract: 1480870 Control circuits for storage heaters DANFOSS AS 23 Oct 1975 [25 Oct 1974] 43576/75 Heading H2H A circuit 8 for controlling the thermal charging of an electric storage heater 1 comprises a signal generator 10, 19 for providing a signal the value of which depends on the outside temperature, an integrator 15 for integrating the signal with respect to time, a sensing circuit 20 which examines the value of the integral and controls the supply of energy to the heater in dependence on the result of the examination, and a re-setting circuit 21 which examines the integral at a pre-set time and controls the integrator to set the integral to a predetermined value if it is not already equal to that value. The circuit 8, which is shown in detail in Fig. 2, includes a logic circuit 22 the input II of which receives a high or low tariff signal from a right tariff meter 3. During the day or high tariff period an output V of the logic circuit enables a transistor switching circuit 16 to connect a charging circuit 17 to the integrator 15. The integrator is a coulometric device consisting of a silver and a gold electrode separated by a silver halide solid electrolyte. At the end of the day and upon changing over to the low tariff period, the logic circuit causes the switching circuit 16 to connect the integrator to a discharging circuit 18 and the rate at which the integrator discharges is made dependent on the outside temperature by means of an outside temperature sensor 10 connected to an amplifier 19. When the integrator is completely discharged its change in resistance is detected by the sensing circuit 20 which causes the logic circuit 22 to supply a heating signal Sh to a thermal control circuit 25 and a relay switching circuit 24. The relay 4 closes its contacts 5 to energize the storage heater 1 from the mains supply 2. The circuit 25 supplies pulses from a circuit 26 to heaters 11, 12, the width of the pulses being modulated in dependence on the outside temperature. A core thermostat 6 controls contacts 7 in dependence on signals from a core temperature sensor 14 and an auxiliary sensor 13 so that heating of the core is stopped at a temperature which varies inversely with the outside temperature. If, at the end of the low tariff period, the integrator has not been completely discharged for example due to high outside temperatures, the logic circuit 22 switches on the resetting circuit 21 which discharges the integrator until the sensing circuit 20 detects the completely discharged state.
