Title: Improvements in or relating to fluid pressure regulating valves
IPC: B60T13/14
Filed: 1944-12-18
Abstract: 593,479. Fluid-actuated valves. BENDIX AVIATION CORPORATION. Dec. 18, 1944, No. 25385. Convention date, Dec. 17, 1943. [Class 135] A pressure-regulating valve in which a motor port can be connected to either a pressure port or an exhaust port has separate inlet and exhaust valves, the former being movable from its seat by the latter and being connected to a plunger-like extension which reduces the effective area on which the supply pressure acts and also to a further pressure-responsive element which acts, under the pressure at the motor port, to urge the inlet valve to closed position. This arrangement reduces the manual effort required to open the inlet valve and prevents the inlet valve from remaining permanently open when relatively high pressures are required at the motor port. Fig. 2 shows a self-lapping valve 16 for controlling fluidpressure brakes which has an inlet port 29 connected to an accumulator or other source of pressure, a port 30 connected to the brakeoperating cylinder and an exhaust port 31. The inlet valve 32, Fig. 3, and the exhaust valve 33 are arranged in an insert 36 screwed into the valve casing and are operated through a piston 34 and a compression spring 54 by a rod 28 actuated by the brake pedal. The piston is in two parts secured together by a hollow bolt 52. A diaphragm 51 is clamped between the two parts and also to the wall of the valve casing. The inlet valve 32 has a piston 61 loosely connected thereto by a pin 63 moving in a hole in the valve stem 64. The piston 61 preferably has a diameter slightly less than that of the inlet valve seat 35 and operates in a bore 62. The inlet valve is also connected to a piston 71 operating in a bore 40 connected to the motor port 30 by ports 47. The exhaust valve has a seat 41 on the piston 34 and is loosely retained by a. flanged nut 44. A stem 39 on the piston 71 extends into a guide opening 43 in the exhaust valve. Specification 562,871 is referred to.

Title: Improvements in or relating to electronic apparatus for detecting a change in position of a conductive or magnetic body
IPC: B61L1/10
Filed: 1960-07-25
Abstract: 944,018. Locating conductive or magnetic bodies. R. G. F. ZINNASER. July 25,1960 [July 28,1959], No. 25824/60. Heading G1N. In apparatus for detecting the proximity of a conductive or magnetic body, the sensing head comprises an oscillatory circuit, fed from a pulse generator the frequency of which is automatically adjusted so that it remains in fixed relationship to the natural frequency of the oscillatory circuit. Compensation is thus arranged for slow changes in reactance of the sensing head due to deposition of moisture or metallic powder. Fig. 1 shows a block diagram suitable for use with the railway axle counting system described in Specification 845, 460 [Group XXX]. The sensing head A, located adjacent a railway track, is fed with pulses from a multivibrator A2 the frequency of which is maintained at 1. 1 times the natural frequency of the sensing head A. This results in the waveform shown in Fig. 3 being present across the sensing head A. The positive pulses are passed by a circuit A4 and integrated at A5 and A6 to provide a D.C. control voltage dependent on the pulse repetition frequency which is used to control the frequency of multivibrator A2. A further sensing head B, located adjacent the track near head A, is connected to a similar circuit. The outputs of integrators A4, B4 are compared by a circuit 14 which gives two outputs of small pulses unless the outputs from heads A, B become different due to the proximity of a train wheel to one head. The difference in the output pulses from circuit 14 is now amplified at 29 and operates a pulse routing gate 15 to direct pulses from a generator 20 to operate bi-stable circuits A1 or B1. Circuits 29, 15 are corrected against long term drift by feedback via integrators 21, 22. Figs. 7, 8 (not shown) relate to suitable transistor circuits not described in detail in the Specification.

Abstract: 601,830. Inductances. TENENBAUM, B. Oct. 4, 1945, No. 25582. [Class 38 (ii)] [Also in Group XL (c)] A band spreading tuning arrangement for use in radio apparatus, comprises a tuned circuit in which a variable capacity and a variable inductance are so arranged that as the value of one decreases, the value of the other increases, throughout the required frequency band. Fig. 1 shows a tuning arrangement suitable for use with a superheterodyne receiver, comprising two ganged condensers a' and a2 respectively associated electrically with variable inductances b<SP>1</SP> and b<SP>2</SP> containing cores f<SP>1</SP> and f<SP>2</SP>. A disc c secured to the condenser spindle is provided with cam surfaces e which engage and move cores f<SP>1</SP> and f<SP>2</SP> axially as c is rotated. The cores f<SP>1</SP>, f<SP>2</SP> are secured in alignment with each other, and are urged against the cam surface by spring g. Each cam comprises two inclined portions, one of which is associated with a particular frequency band over which spreading is required, the arrangement then being such that inductance varies inversely as capacity. The other inclined portion of each cam is associated with the interval between the required frequency bands, the arrangement then being such that capacity and inductance increase or decrease simultaneously, so that the unimportant interval band is covered by a small tuning movement. The cam formation e may be constituted by an adjustable ribbon secured to disc c by means of screw-threaded members. Where two short wave ranges are required, a second series of cams associated with additional tuning inductances may be provided on disc c. A .modification provides for a number of cams to be associated with each frequency band and arranged to operate the cores of separate inductances simultaneously.
