Title: Improvements in electrical controlling apparatus
Inventor: BOUNDY JAMES REILLY
IPC: G05B11/01
Filed: 1952-08-13
Abstract: 723,825. Automatic liquid-level control systems. EVERSHED & VIGNOLES, Ltd. Aug. 7, 1953 [Aug. 13, 1952], No. 20386/52. Drawings to Specification. Class 38 (4). In the system of Specification 704,885 the outlet from a tank is controlled by an error signal, from a float-level detector, including an integral component which will build up if the inflow to the tank ceases temporarily ; according to this invention a contact making ammeter is connected in the control circuit of the outlet valve to restrict the current to a value corresponding approximately to the limits of travel of the valve. As described the contacts connect resistors in the grid circuit of a thermionic valve from which the integral component is derived, to produce a change in the opposite sense to the error signal, whereby the controlcurrent cycles about a limiting value. Specifications 688,462 and 688,464 also are referred to.

Title: Method for the simultaneous transmission of binary signals
IPC: H04L5/12
Filed: 1966-05-09
Abstract: 1,130,023. Multiplex signalling; data transmission. STIFTUNG HASLER-WERKE. 9 May, 1966 [10 May, 1965], No. 20500/66. Headings H4L and H4P. In a system for the simultaneous transmission of binary signals on two channels by means of two carriers of the same frequency but phasedisplaced by 90 degrees, the signal elements of the signals of the two channels are displaced by half the signal element period, the changeover between the binary conditions occurring in accordance with a cosine function whose halfperiod is equal to the signal element period, each carrier being amplitude modulated with one of the signals thus obtained and the modulated carriers being combined for transmission. A single input signal may be divided to form the two channels. Transmitter, Fig. 1.-The two signal sources produce square waves D and E whose elements are shifted with respect to each other by half the pulse period, Fig. 5 (not shown) and are converted at 3, 4 into signals D<SP>1</SP>, E<SP>1</SP> in which the change from one binary condition to the other takes place in accordance with the cosine function specified. Signals D<SP>1</SP>, E<SP>1</SP> are applied to modulators 7, 8 respectively together with quadrature carrier waves 5, 6 and supplied via a common low pass filter 9 and amplifier 10 to line or the modulator of a radio transmitter. Receiver, Fig. 3 (not shown).-The incoming signals are fed via a bandpass filter (20) to synchronous detectors (21, 22) provided with quadrature carrier signals at (23, 24) respectively. The outputs of the detectors are supplied via filters 25, 26 respectively to signal recognition circuits 27, 28 for utilization. Single signal input.-A single binary signal (A) may be distributed over two channels (B, C), Fig. 2 (not shown) and converted into a pair of signals (D, E), Fig. 5 (not shown), each comprising bits at half the rate of the input signal (A) and being the differential form of (B, C) respectively, the signals (D, E) being supplied to the arrangement shown in Fig. 1. It is shown that the resulting composite signal (F) is a carrier which is frequency-shifted in correspondence with the input signal (A), the mean carrier frequency representing " 0 " and either of the side bands representing " 1 " and this may be detected at the receiver by a conventional frequency discriminator. Alternatively the carrier and two side bands may be detected separately and used for error detection, since certain sequences of carrier and side band would not be present with normal operation.

Title: Improved automatic brake adjuster
Inventor: DOWELL FREDERICK SIDNEY
IPC: F16D65/56
Filed: 1961-06-10
Abstract: 1,001,267. Disc brakes. DUNLOP RUBBER CO. Ltd. June 4, 1962 [June 10, 1961], No. 21041/61. Heading F2E. An automatic adjuster for a disc brake of the kind wherein a tie-rod interconnects a pair of applying levers carrying pads adapted to engage opposite faces of a disc, comprises a nut threaded on the tie-rod and having circumferentially spaced saw-teeth adapted to co-operate with complementary teeth on an adjuster wheel loosely mounted on the tie-rod, spring means to rotate the adjuster wheel in one direction, means to prevent rotation of the nut in the opposite direction, and a connection between the adjuster wheel and a brake operating lever, whereby the adjuster wheel is rotated to slip a tooth when wear becomes excessive. As shown, the adjuster is associated with a disc brake having a pair of applying levers 1 carrying pads 2 for engagement with a disc 3, one lever 1 being connected to an operating lever 6 which in turn is connected to the other lever 1 by tierod 4 threadedly engaging a nut 10 which bears against a trunnion block 5 carried by the lever 6, the tie-rod passing loosely through an aperture in the trunnion block. The nut 10 is provided with sawteeth as shown engaging complementary sawteeth on an adjuster wheel 11. A pair of helical interwound springs 16, 17 are held in compression between diametrically opposite points on the wheel 11 and a support 11 which is located against inturned flanges on one end of a split sleeve 12 of resilient material arranged to grip the nut 10 and positioned by apertures engaging projections 13, 14 carried by the trunnion block 5. The aperture engaging projection 14 is elongated circumferentially and the arrangement is such that the sleeve grips the nut tightly if it tends to rotate in the direction to increase pad clearance, but allows it to move in the clearance reducing direction, the springs 16, 17 being prewound to balance the friction force in the latter direction. A projection 8 is provided on the adjuster wheel and extends through an aperture in the sleeve 12 and through a rubber sheath 18 which encloses the mechanism. In the arrangement shown in Fig. 4, the projection 8 engages a lug 7 on the lever 6 such that the wheel 11 is rotated in a direction to wind up the springs when the brake is applied, excessive wear causing the wheel to slip a tooth on the nut 10 so that on subsequent brake release the springs overcome the friction between the sleeve 12 and the nut to effect adjustment. In an alternative arrangement (Fig. 5, not shown), the brake operating lever may be caused to rotate the wheel 11 in the direction to slip a tooth on the nut during release instead of during braking, the springs acting to rotate the nut during braking until the braking force is such that friction between the nut and the trunnion block 5 prevents further adjustment.

The shields are preferably rigidly attached to the rotor so as to project at all times by 60% to 90% of the distance between the rotor wall at the point where the shield is mounted and the peripheral wall of the engine cavity. A shield 41 may be mounted in a slot 42 with a pin 43 being force-fitted through the rotor and shield to provide the rigid attachment, or the shield 45 may be welded in the slot at 46. Alternatively, a shield 48 can be T-sectioned and inserted in a corresponding groove 47. Also shown are an integral shield 49 and a shield 51 freely slidable in a slot 50. The shields may be slotted, and if more than one shield is used on one side of the tip seal, then the slots are offset from one another Figs. 5 and 6 (not shown). The shields are preferably metallic with high melting point, high thermal conductivity, moderate ductility and high creep strength.

In a fuel injection pump, the piston 32 is reciprocated by the cam 34 and rotated from a pinion 37 on the camshaft so that an axial groove 52 in the piston registers in turn with a number of outlets connected to the engine cylinders. The delivery ports 49 are at a different level in the cylinder to the suction ports 48 and delivery commences when the trailing edge of the groove 52 closes a suction port and ends when a groove 53 in the piston opens the suction ports 48. To vary the delivery and beginning of injection, the phase of rotation of the plunger relative to the camshaft is varied by arranging that the driving sleeve 39 rotated by the pinion 37 is splined at 40 to a slider 41 which has internal inclined grooves 42 engaged by members 43 attached to a plunger guide 44 that has slots 45 engaged by pins 46 on the plunger; the slider 41 is adjusted axially by a lever 54. Alternatively the pump barrel 31 may be adjusted by rotation. The beginning of injection may be constant and the end varied bv varying the phase of the reciprocation of the piston relatively to the camshaft by rotation of the cam 34 on the shaft 36. In a modified construction, the groove 53 is omitted and the end of injection is determined by the groove 52 opening the vent adjacent suction port. Specification 647.687 is referred to.
