Title: Pressure-regulators for fluids
Inventor: MENNESSON ROBERT MAURICE
IPC: G05D16/06
Filed: 1959-10-12
Abstract: 871,273. Valves. SOC. D'APPLICATIONS ET DE CONSTRUCTIONS POUR MATERIEL AUTOMOBILE. Oct. 12, 1959 [Nov. 3, 1958], No. 34515/59. Class 135. A pressure-regulator device for supplying fluid at a practically constant predetermined pressure comprises a main chamber 4 having a supply outlet 8 and communicating with a source of fluid at a pressure which differs from atmospheric pressure by an amount greater than, and in the same direction as, the difference between the constant pressure and atmospheric pressure, a passage 10 leading from the chamber to atmosphere being normally closed by a valve 11 which tends to be opened by the action of the said pressure difference, the valve being supported by at least one deformable diaphragm 13. As shown in Fig. 1, the valve 11 is attached to a rod 12 which is supported at one end by the diaphragm 13 and at the other end by a second diaphragm 14, the latter defining one wall of a dashpot chamber 16; the valve is loaded to the closed position by its own weight and the diaphragms may be of a fabric coated with natural or synthetic rubber. In operation, fluid such as air is fed from a pressure source 7 through a restrictor 6 into the chamber and passes out through the outlet 8. Since the incoming pressure is greater than that required in the chamber, the excess is relieved by the air passing through a port 15 in the diaphragm 13 and leaking-off through the valve 11. The action of the valve is stabilized by the dashpot chamber 16 which communicates with the chamber 4 via a restricted orifice 17; the chamber 16 may communicate with atmosphere through a port controlled by a variable throttle. A deflector 18 is provided for directing condensation, oil or dirt into a trap 19 which drains away through a port 20. In the alternative construction shown in Fig. 2 for applications wherein the pressure in the chamber 4 is required to be below atmospheric, the valve 11 is reversed, the dashpot chamber 16 then being at the top; in the latter construction the deflector 18 is dispensed with.

IPC: H03M1/00
Filed: 1964-08-24
Abstract: 1,057,696. Selective signalling. SOLARTRON ELECTRONIC GROUP Ltd. July 29, 1965 [Aug. 24, 1964], No. 34543/64. Heading G4H. In a voltage digitizing system an integrating capacitor C1, Fig. 2, is so arranged in a cyclically operating loop that during a first portion of cycle (see Fig. 1) the potential of the capacitor falls to zero under the joint action of the input voltage ( + ve) and a reference voltage VR ( - ve) and a counter N counts clock pulses via a gate G1, and during the second portion of each cycle the potential of the capacitor rises under the action of the input voltage by itself and the counter counts clock pulses via a gate G2 until it is full when a new cycle commences. With appropriately chosen parameters the loop described eventually reaches a condition of stable equilibrium in which the transition from the first part to the second part of each cycle does not alter from cycle-to-cycle. The count reached at the end of a first part, which is determined by opening a switch S2 at the beginning of the cycle and thereby preventing the counter receiving any clock-pulses after the end of the first part of the cycle, is then proportional to the input voltage. The stable equilibrium condition can be detected automatically by examining C2, G3 the lowest significant bit in the counter at the end of successive first parts.

A phase shift sine wave oscillator has an amplifier V whose output is connected to its input through a network as shown wherein F, G are capacitors (or resistors) and Q<SP>1</SP>, S<SP>1</SP>, T<SP>1</SP> are resistors (or capacitors), the element P being either a switch or a resistor or a capacitor. If the amplifier V instead of being a voltage amplifier is a current amplifier, its input and output connections to the network are reversed. The output frequency is varied, without changing the voltage dividing ratio at E and therefore without affecting the output amplitude, by any of the following methods: (a) by opening or closing a switch constituting the element P to give two different frequencies whose ratio depends on a given relationship between F, G, Q<SP>1</SP>, S<SP>1</SP>, and T<SP>1</SP>; (b) by varying a resistance (or capacitance) constituting the element P to give a range of frequencies between the two frequencies in (a); or (c) varying a resistance (or capacitance) constituting the impedance T<SP>1</SP> provided that the capacitors (or resistors) F, G are equal and that P<SP>2</SP> = Q<SP>1</SP>. S<SP>1</SP>. In these arrangements, the element P is of the same impedance type (i.e. resistor or capacitor) as Q<SP>1</SP>, S<SP>1</SP> and T<SP>1</SP>. If the amplifier is a differential amplifier, its second input is fed from the junction of two resistors connected from the output to earth.
