Title: Improvements in or relating to pulse converters
IPC: H03K9/08
Filed: 1965-08-06
Abstract: 1,062,675. Pulse modulation circuits; transistor gating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 16, 1965 [Aug. 19, 1964], No. 34944/65. Headings H3T and H4L. In a circuit for demodulating duration-modulated pulses, control pulses applied at A cause transistors T 1 , T 2  to conduct and capacitor C 1  to be charged to a reference voltage VB. Duration modulated pulses applied at B cause capacitor C 1  to discharge via resistor R 3  and transistor T 3  for the duration of the pulse so that a residual voltage inversely proportional to the pulse duration remains across C 1 . A further control pulse applied at C at the termination of a signal pulse causes transistor T 6  to conduct and one or other of the opposite conductivity transistors T 4  or T 5  to conduct (dependent upon the relative voltages on capacitors C 1 , C 2 ) so that capacitor C 2  assumes the residual voltage on capacitor C 1  and provides a direct voltage at D varying in amplitude in accordance with the input pulse modulation. Transistor T 6  preferably is of the symmetrical type. The output signal may control the frequency of an oscillator.

Title: Control system for fluid-driven motors
IPC: F15B13/04
Filed: 1974-08-08
Abstract: 1427503 Valves CATERPILLAR TRACTOR CO 8 Aug 1974 [8 Aug 1973] 35040/74 Heading F2V [Also in Division F1] In the circuit shown, Fig. 1, in which a main control valve 17 controls an actuator 10 and is itself controlled by a pilot valve 25 valves 78, 79 prevent cavitation if the actuator tends to overrun by opening to connect opposite sides of the piston. When the piston is being retracted, fluid is supplied from an inlet 16 of valve 17 through a passage 69 to port 11 of the actuator and fluid returns from a port 12 through a passage 64 to a reservoir 14. If the actuator starts to overrun, a pressure drop occurs in the passage 69 which is communicated to a chamber 84 through a bore 85. At the same time, a pressure increase occurs in the passage 64 and this is transmitted through the drain passage 74 to a passage 75. This pressure difference across the valve 78 lifts it against a spring 86 so that fluid being discharged from the port 12 is supplied to the port 11. Valve 29 opens in a similar manner, if required, when the piston is being extended. The pilot valve has a " float " position F, Fig. 4, in which the actuator 10 is free to move in either direction as determined by external forces. In this position pilot pressure from an inlet 28 is transmitted to a spring chamber 52 of valve 17 so that port 11 of the actuator is supplied with fluid whilst port 12 is connected to reservoir. In addition a groove 91 in the pilot valve is connected to the reservoir. This allows pressure in a line 108 to move a spool 106, of a float valve 93, to the left to close a line 99 and connect a line 95 to the reservoir. This vents the spring chamber 84, Fig. 1, to reservoir so that the valve 78 is lifted from its seat by pressure in the passage 69 which acts against a shoulder 87, or in response to pressure in passage 75 received through passage 74.

Title: Improvements relating to time base circuits
IPC: H03K4/12
Filed: 1938-12-02
Abstract: 522,165. Valve generating circuits. KOLSTER-BRANDES, Ltd., SMYTH, C. N., and SHANNON, D. S. B. Dec. 2, 1938, No. 35165. [Class 40 (v)] A time-base circuit of the non-self-running type for television systems, oscillographs &c. includes means for applying to a control electrode of a discharge tube for periodically charging or discharging a condenser a bias which changes to render the tube more susceptible to triggering pulses as they become due. In the circuit shown in Fig. 1 a resistance R1 and condenser C1 are connected in parallel in the anode circuit of a grid-controlled valve V, to the grid of which synchronizing impulses are applied over a condenser C2. On receipt of an impulse the valve conducts, the condenser C1 is rapidly charged through the valve, and then slowly discharges through the resistance R1 until the next impulse is received. To reduce the effects of interference the control grid is connected to the slider of a potentiometer R. While the condenser C1 is discharging the anode voltage rises, and a fraction of this rising voltage is applied to the control grid in addition to the constant bias from the network R3, C3. Over the greater part of this time the grid bias is too negative to allow interference pulses to trigger the valve. Alternatively a discharge tube of the deflection control type may be used for charging and discharging the condenser as shown in Fig. 2. The electron tube V2 comprises a cathode K, focussing electrode F and two anodes A1 A2, with a deflecting plate A3 for deflecting the stream from one anode to another. A relaxation condenser C is connected between the cathode K and the main anode A2, in series with which is a condenser-charging resistance R4. A current limiting resistance R5 is inserted in the connection to the auxiliary anode A1. Television signals are applied to the plate A3 and normally deflect the beam to the auxiliary anode A1 so that the condenser C charges over the resistance R4. On the arrival of a synchronizing pulse the potential of the plate A3 becomes less negative and allows the beam to fall on the main anode A1 and discharge the condenser. A fraction of the anode voltage is applied to the deflecting plate A3 which is thereby prevented from becoming highly positive, due to the arrival of an interfering pulse, until the condenser C has become charged. A pentode amplifier may be incorporated in the envelope of the deflection control tube as shown.

Abstract: 788,608. Aircraft feel simulators. HOBSON, Ltd., H. M., SMITH, C. P., HULLEY, B. J., and PUGH, A. T. Oct. 26, 1955 [Dec. 7, 1954], No. 35409/54. Class 4. An aircraft fitted with power or servo-tab operated ailerons includes a feel simulator comprising a housing and a piston therein linked to a control column so as to be moved by departure of the column from neutral position, and means for establishing in the housing a hydraulic pressure opposing movement of the piston and increasing the pressure with increase in the rate of roll. In Fig. 1, the pilot's control stick 10 operates the ailerons 12 through servo-mechanism 13, 14, and is coupled to the piston 17 of a jack 16 pivoted to the aircraft, the jack containing fluid at a control pressure which offers resistance to the movement of the pilot's control stick from its neutral position. The control pressure fluid is supplied by a conduit 21 from a hydraulic valve block 22, supplied at a port 23 with fluid under pressure by a pump 25 and a reservoir 25<SP>1</SP> connected to an exhaust port 26 on the valve. Bob weights 49, 50 mounted on levers pivoted to the fuselage and connected by links 52, 53 to a lever 47 pivoted on the aircraft at 48, exert a torque on the lever proportional to the square of the rate of roll, due to centrifugal force. The lever 47 is also connected to a damper 55, and has an integral part 46 abutting a push rod 44. The hydraulic valve block 22, Fig. 2, comprises a valve 28 having lands 29, 30 and a waisted part 31 co-operating with a pressure part 23 an exhaust port 26, and a port 41 leading to the control pressure conduit 21. The control pressure acts on one end of valve 28 through a passage 34, and a spring 35 acts on the other end through a push rod 37 and a relief valve 38. The push rod 44 abuts a member 43 which forms one abutment for the spring 35, so that if the push rod is urged upwardly by the bob weights due to an increase in the rate of roll, the force of the spring is increased, and the valve 28 moves upwardly against the control pressure, placing the pressure port 23 in communication with the control pressure port 41, raising the control pressure until this is sufficient to return the valve 28 to its neutral position. Similarly a decrease in the rate of roll decreases the control pressure. The valve is also moved to allow fluid to flow into and out of the jack 15 as the pilot moves his control stick. Should the valve stick, the pilot can still move his stick, opening the relief valve to put the jack in communication with the exhaust port 26 through passage 40. Specification 734,437 is referred to.
