Title: Delivery restricting equipment for use with pumps
IPC: B67D7/44
Filed: 1958-09-30
Abstract: 871,172. Dispensing liquids. SLADEN, C. B. Sept. 30, 1959 [Sept. 30, 1958], No. 31116/58. Class 116 An electronic timing device cuts off the delivery of a petrol pump after a period corresponding to a predetermined maximum delivery. When the pump is out of use a capacitor Cl is charged and renders a pentode VP non-conductive. When the pump 10 is taken into use, a switch 11 is closed to complete a circuit through a high resistance transformer primary Tl, the current being insufficient to operate the pump motor. The current induced in a low resistance secondary operates a bridge circuit to actuate relay L/2 which closes contacts L2 to prepare the pump operating circuit and closes contacts L1 to discharge capacity Cl, rendering pentode VP conductive which energises relay K/3 to close contacts K3 and open contacts K2, whereby the pump motor starts operating. Simultaneously relay KK/1 opens contacts KK1 to break the discharge circuit of capacity C1 which starts to recharge. After a predetermined time interval, corresponding to the maximum permitted delivery, the charge on capacity C1 reaches a value to render VP non-conductive which deenergises relay K/3 to open contact K3 and close contacts K2 whereby the pump motor stops automatically if it has not already been stopped by the operator. Relays L/2 and KK1 remain energised, however, so that capacity C1 cannot be discharged to render the pump operative again until relay L/2 has been released by opening of the operator's switch 11.

Patent GB-521947-A (GB)
Title: Improvements in or relating to the regulation of gas flow
IPC: B64D13/04
Filed: 1938-10-29
Abstract: 521,947. Regulating fluid flow. BENDIX AVIATION CORPORATION. Oct. 29, 1938, No. 31351. Convention date, Oct. 30, 1937. [Class 135] Consists in a gas flow regulator for controlling the supply of gas to a gas-consuming device under variable pressure conditions, e.g., the flow of oxygen to the cabin or to a mask worn by the pilot or passengers on aircraft. Use is made of a porous element one side of which is exposed to the changing pressures,. the other side receiving the gas at constant pressure, the effect being to obtain a flow of gas which is a linear function of the difference of pressures on the two sides of the element and therefore also of the variable pressure at the place of consumption. A casing 10, Fig. 2, is supplied from a source of oxygen by a pipe 11 controlled by a valve 12 and having a nozzle 13 adapted to be controlled by a valve 14 carried by a lever 15 pivoted at 16. An evacuated diaphragm or aneroid 18 is connected to the lever at 17 and, at the free end, is connected a spring 19 which just balances the force of the diaphragm at a pressure within the casing equal to that at, say, an altitude of 15,000 feet. A porous element 21 leads to the pipe 22 conveying the gas to the place of consumption. A relief valve is provided at 24. Thus, fluctuations in pressure in the casing 10 produce such movements of the valve 14 as to tend to keep the pressure constant and an approximate linear flow is thereby obtained. True linear flow, however, is obtained by the modified apparatus shown in Fig. 3, in which the supply pipe 11, controlled by the valve 14, leads into a chamber 26 which communicates with the outlet chamber 36 through the porous diaphragm 21. The valve 14 is mounted on a lever 27 pivoted at 27a and loaded by a spring 28. A lever 29 pivoted at 30 has, at one end, an adjustable screw 31 bearing on the spring 28 and at the other end 32 a connection with an aneroid diaphragm 33 urged to expanded position by a spring 34. A link 35 connects the lever 29 with a bellows 37 loaded by a spring 38 and communicating through an aperture 35b with the chamber 26. The gas is led away through the pipe 22. In this modification, true linear flow is obtained by arranging that the average of'the pressures on the two sides of the plug is constant and equal to the pressure at which the device begins to function.

Title: Pulse code modulation encoding and decoding apparatus
IPC: H03M1/00
Filed: 1964-08-04
Abstract: 1,038,540. P.C.M. systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 4, 1964 [Aug. 6, 1963]. No. 31490/64. Heading G4H. In a P.C.M. system, bipolar P.A.M. samples are applied to a pulse compressor the output of which is fed to a polarity detector and a fullwave rectifier; the latter being connected to an amplitude quantiser and the polarity detector adding a polarity bit to the output of the quantiser. The quantiser comprises seriallyconnected stages 11-15, Fig. 2, each having a reference input terminal 20 to which potentials of 32, 16 ... 2, 1 volts are applied. The rectified P.A.M. input 16 is applied to a comparator comprising diode 18 and resistor 19 in stage 11, gate 22 being normally opened by the stable output of monostable circuit 25. If the input 16 is less than 32 volts, there is no output from comparator 18, 19, and after a 1-bit delay, the input pulse passes through gate 22 to form the input of stage 12 where it is compared with the 16 V. reference. If the input 16 is greater than 32 volts, comparator 18, 19 produces an output pulse having an amplitude equal to the difference between the input and the 32 volts reference. After a 1-bit delay at 27, this difference pulse forms the input to stage 12, gate 22 being closed by the triggering of circuit 25. The output of comparator 18, 19 also triggers a blocking oscillator 29 to provide the most significant code bit. The remaining stages operate in a similar manner and produce their outputs at 1- bit intervals. The final stage comprises diode 31 and resistor 32 connected to 1 volt reference. The polarity bit is added in the first time slot by OR gate 7. The decoder comprises a tapped delay line 36, Fig. 3 (not shown), the parallel output of which passes through gates 45, which are opened by a timing pulse, and sets bi-stable circuits 52-57 and 58a. The polarity bit stored in 58a selects either gate 70 or gate 71 so that when the delayed timing pulse enables these gates, the output from summing resistors 58-63 is applied to the output either directly or through an inverter 79. The reconstituted P.A.M. output is applied to an expander to obtain the original signal. Alternatively the expansion can be performed by resistors 58-63.

Abstract: 661,553. Valve circuits for radio reception; frequency modulation. BRITISH THOMSONHOUSTON CO., Ltd. Dec. 8, 1949 [Dec. 18, 1948], No. 31552/49. Classes 40 (v) and 40 (vi). A screen-grid valve operating as a normal grounded-cathode amplifier on one frequency band is switched to function as a triode grounded-grid amplifier on another band of higher frequency. As applied to a superheterodyne receiver convertible for either amplitude (A.M.) or frequency (F.M.) modulated signals, the valve 8 is used in the first instance (A.M.) as an intermediate-frequency amplifier, its cathode being grounded by switch 32. The receiver then comprises a tuned loop aerial 1 together with an optional external aerial 3, a frequency-changing stage 5, an intermediate-frequency amplifier comprising the valve 8 and having tuned input and output circuits 7, 9 respectively, and a detector 10 feeding audio circuits 11. On the higher frequency (F.M.) band the valve 8 is used as a high-frequency amplifier, a dipole aerial 14 being coupled over a cable 29 and blocking condenser 31 to its cathode circuit, which comprises a biassing network 27 in series with an inductance 26, the circuit being broadly tuned by the stray capacities to the centre of the band. The grid is grounded by switch 32, which is in the reverse position. The output is taken from the screen, to which the anode is also coupled via the primary tuning capacity 22 of the circuit 9; the output circuit includes an inductance 23 broadly resonant, in conjunction with stray capacity to the centre of the band, and a tunable circuit 34 for selecting the desired signal within the band. The circuit 34 is coupled over a blocking condenser 38 to the input of the frequency-changer 5, switch 6 being reversed. A different intermediate-frequency is used on the F.M. band and is selected by means of a tuned circuit 16, being applied to a super-regenerative detector 15, from which demodulated signals reach the audio stages 11 over switch 12 in reversed position.

Abstract: 447,118. Fluid -pressure brakes. GRESHAM & CRAVEN, Ltd., GRESHAM, J. N., and MARSH, G. C., Ordsall Lane, Salford. Nov. 7, 1934, Nos. 31984/34 and 21258 /35. [Class 103 (i)] Fluid-pressure brakes particularly for railway vehicles, controlled in accordance with the speed of the vehicle comprises a valve i between the driver's valve m and the train pipe, which closes when a certain train pipe pressure has been attained, and is controlled by a pressure which is proportional to the speed of the vehicle, a spring j and train pipe pressure acting on a diaphragm k. The brake described is a vacuum brake. Another valve p is also provided which connects a vacuum reservoir q to the train pipe when the speed has been reduced, in order to reduce the power of the brake application progressively. A compressor a is driven from a wheel of the vehicle and charges a reservoir c, the pressure in which acts on a piston g on the stem h of the valve i. The reservoir c is provided with a leak d so that pressure does not commence to build up till a definite speed has been attained. When the brakes are applied, the valve i is closed when train pipe vacuum has decreased by a certain amount and the brakes are applied with only a part of the maximum force available unless the speed is high in which case the pressure developed in the reservoir c holds open the valve i until a greater braking force has been exerted. The valve p is also controlled by the pressure in the reservoir c, the train pipe pressure on a diaphragm a and a spring u. If the speed has been high, the reduction in train pipe vacuum causes a sufficient pressure above the diaphragm s to open the valve p when the pressure in the reservoir c falls when the train slows down, and connects the vacuum reservoir q to the train pipe in order to reduce the brake pressure as the speed falls. The train pipe is exhausted by means of a check valve v.
