Patent GB-883364-A (GB)
Title: Improvements in apparatus for measuring the mass flow rate of a fluid
IPC: G01F1/82
Filed: 1959-08-12
Abstract: 883,364. Flow-meters. BENDIX CORPORATION. Aug. 12, 1959 [Sept. 5, 1958; Sept. 17, 1958], No. 27610/59. Class 40 (1). [Also in Group XXIX] In a mass-flow meter of the kind shown in Specification 857,052 wherein the rate of flow is represented by the angular displacement of two coaxial members, the members carry circular segments or sectors, one end of each of these being angularly coincident when the flow rate is zero, and measurment is made of the relative angular displacement of these segments when the fluid is flowing. In Fig. 1 a member 30 is driven constantly by a motor 20 and a further coaxial member is carried round with it by a spiral spring 45 which connects the two members. Fluid enters at 11 and flows through channels 37 and 40, thereby causing a drag on the member 31 and introducing a relative angular displacement between the two members. Circular segments 50, 51 (Fig. 2, not shown), are attached to the members and are adjacent to two of the limbs of an E-type transformer having two opposed primary windings 57, 58 and a secondary 59. If there is no angular displacement between the members, the ends of the segments coincide, the reluctance of the path between 57 and 59 is constant throughout a revolution and no output comes from the secondary. Fluid flow causes one segment to lag behind the other so that a gap appears between the segments and the secondary gives an output for a time proportional to the rate of flow. The output from the E-type transformer can be turned off instead of on by the gap between the segments. Preferably the latter overlap at their other ends so that only one gap passes the transformer per revolution. The E-type transformer can be replaced by a condenser whose capacitance is changed by the gap between the segments. Alternatively the segments can be replaced by opaque sectors in otherwise transparent discs and the angular displacement measured photo-electrically. The flow-meter can be modified so that the members 30 and 31 are at rest with a definite angular displacement (assuming constant rate of flow) and the sensing device rotates. In this case the fluid is given a certain initial angular velocity by means of an impeller and is then passed through stationary vanes until its angular velocity is again zero. The pulse-duration signal can be measured as in Specification 883,365.

Title: Improvements in mechanical time fuses for projectiles
IPC: F42C9/04
Filed: 1928-09-27
Abstract: 319,144. Liebergeld, P. Sept. 27, 1928. Projectile fuzes.- Relates to clookwork time fuzes in which a pointer 6 is released when the projectile is discharged, for example by the set back of a pivoted locking member 7, and then bears on a timing ring 10 until at the appointed time it escapes through a gap in the timing ring and thereby causes the firing of the fuze. According to the invention, in addition to the locking member 7, there is provided on the stationary frame of the clockwork a securing member 14 entirely independent of the timing ring and adapted to prevent the pointer 6 from passing through the gap in the timing ring if this gap is opposite the pointer at the moment the projectile is discharged. The securing member 14, however, does not prevent the rotation of the pointer 6; and after a short time the pointer 6 is free from the securing member and can bear on the timing ring 10 and afterwards pass through its gap. This arrangement ensures that the fuze cannot be fired until the projectile is at a safe distance from the gun. In the Figure here shown, the pointer 6 rotates with the axial spindle 2 of the the clockwork and moves up to the timing ring 10. In a modification, the pointer slides radially to bear on the timing ring.

Title: Improvements relating to electrical signal-separating apparatus
Inventor: ALEXANDER LUDOVIC WILLIAM GRAN
IPC: G05B19/16
Filed: 1959-08-14
Abstract: 923,898. Electric copying machines. FERRANTI Ltd. Aug. 10, 1960 [Aug. 14, 1959], No. 27790/59. Class 38 (6). [Also in Group XL (c)] In a machine tool control system, gating circuits provide for the separation of two pulse signals which are either recorded on a common magnetic track or received from an unspecified source. Four channels are provided, one carrying reference pulses, Fig. 2 (a)R, the other three carrying pulses modulated in phase relative to the reference, in order to control the movements of the machine tool along 3 axes. At intervals, an auxiliary binary coded signal is introduced by either marking or not marking the 3 control signals (and the reference signal if desired) to provide the appropriate code combination. The marking is effected by "notching," Fig. 2 (b) eight successive control pulses in the selected channel by means of auxiliary pulses. For each channel, a reading head 12, Fig. 1, is provided. This controls a bi-stable circuit 14 the output of which is the waveform as originally recorded, Fig. 2 (d). The leading edge of each main pulse triggers a blocking oscillator 15 to generate gating pulses of opposite polarity, Fig. 2 (e) and (f), these pulses being shorter in duration than a main pulse, but long enough to include an auxiliary pulse. Gating the incoming signal at 16 and 17 with the positive gating pulses reconstitutes the main signal free from auxiliary pulses, and gating the incoming signal at 22 with the negative gating pulses produces the auxiliary pulses only, Fig. 2 (h). These are integrated at 23 so that if at least 6 out of the 8 auxiliary pulses are present, a signal is passed via a bi-stable circuit 25 to a binary signal decoder 33. The outputs of the other channels are also applied to decoder 33, provision being made that the arrival of a group of auxiliary pulses in any one of the channels first resets at channels 8 the decoder 33 from its existing reading.

Title: Improvements in or relating to infinitely variable change speed gears
IPC: F16H13/14
Filed: 1956-09-11
Abstract: 870,914. Variable-speed gearing; shaft couplings; universal joints. PERBURY ENGINEERING Ltd., and PERRY, F. G. DE B. Sept. 9, 1957 [Sept. 11, 1956], No. 27819/56. Class 80 (2). In an infinitely variable speed gear having first, 10, and second, 11, coaxial torus discs connected by rollers 13 precessionally rocked to vary the transmission ratio and in which the pressure between the discs and the rollers is increased with the load on the input shaft 1 of the gear. a flexible coupling connects the input shaft 1 with the means for generating the frictional engaging pressure. The means for generating the engaging pressure in a Hayes type gear comprises cam surfaces 8, 9 and tapered rollers 15, as described in Specification 870,913. The end of the input shaft 1 is formed as a drum 6 having axially-extending dogs 7 engaging dogs on a coaxial ring 31 to which is welded a ring 32 having offset parallel faces. The periphery of the ring 32 is riveted to a plane coaxial disc 34. The driving-cam 8 is similarly attached to a disc 36 through dogs 41 and a ring 38. The discs 34, 36 are connected by a ring 35 of synthetic rubber bonded thereto, to provide a flexible coupling. In modifications the rings 32 38 are flanged inwardly for connection by a pleated spring welded to the flanges, or are flanged outwardly and connected by rubber rings bonded to the flanges and to an enveloping cylinder. In other modifications, the drum 6 and driving cam 8 are formed with radial slots engaging radially disposed spring strips retained by a cover member, alternatively one spring carrier may be dogged to the cam 8 and the springs arranged at an angle to the axis of the gear unit.

Title: Fluid pressure servomotor
IPC: B60T13/565
Filed: 1966-06-22
Abstract: 1,144,944. Hydraulic brakes. BENDIX CORP. 22 June, 1966 [28 June, 1965], No. 27856/66. Addition to 1,139,053. Heading F2F. In a fluid pressure servomotor adapted to assist application of an hydraulic master cylinder 88 supplying fluid to the wheel brakes of a vehicle via aperture 98, the servomotor consists of a front movable wall formed by a diaphragm 20 and a support plate 50 separating a forward vacuum chamber 110 and a rear control chamber 112, a valve member 40 being carried by rearwardly extending support plates 36, 38 formed conjointly by a rear movable wall which also supports a hollow diaphragm 26 filled with atmospheric pressure. In the position shown, vacuum from the inlet manifold is supplied via connection 104 to each side of the diaphragm 20 via conduits 48, 46, 44 and passage 113. When the brake pedal (not shown) is depressed the push rod 68 allows the poppet valve 54 to seat on a valve seat 52 to close off the vacuum supply to the chamber 112 via the passage 113. Further movement of the plunger 70 removes the plunger seat 72 from the poppet valve to communicate atmospheric pressure passing internally of the poppet valve from a filter 116 to the control chamber 112 via passage 113. During this initial movement the forward face of the plunger 70 approaches the face 80 of a reaction plunger 78, located within a force transmitting member 84, but does not contact the latter until hydraulic pressure developed in the master cylinder 88 is sufficient to cause the wheel brake cylinders to expand the brakes shoes into contact with the brake drums. During this operation the pressure in chamber 112 is less than the atmospheric pressure between the chamber 114 of the hollow diaphragm 26 so that the hollow diaphragm will remain expanded to hold the whole rear movable wall to the rear. The push rod 68 will only move a sufficient amount to open the valve seat 72 of the plunger 70 and thereafter will be held from following up the motion of the front movable wall. As the pressure in the master cylinder 96 builds up the reaction plunger 78 is moved to the right to compress the spring 82 and abut the forward face of the plunger 70 to provide reaction forces for the operator after the hydraulic brakes have been applied. When the chamber 112 reaches atmospheric pressure the hollow diaphragm 26 will collapse to permit push rod 68 to act upon the reaction plunger 78 so that the fluid in the master cylinder may be actuated by the operator directly in the event of a power failure. The servomotor may be operated by superatmospheric pressure, such that superatmospheric pressure could be fed to the valve housing and the hollow diaphragm. The connection 104 would be open to atmosphere.
