Patent GB-859070-A (GB)
Title: Accelerometer
IPC: G01P15/13
Filed: 1959-01-20
Abstract: 859,070. Accelerometers. CENERAL PRECISION Inc. Jan. 20, 1959 [June 16, 1958], No. 2068/59. Class 40 (1). [Also in Group XIX] An accelerometer has an arm pivoted at one end by means of a floating beam fixed at or near its centre to the end of the arm, which it straddles, and connected through resilient means to a stationary bracket fixed to a base-plate. The pivot is thus readily adjustable to bring the physical axis of the arm into alignment with, or parallel to, its inertial axis. The free end of the arm carries signal-producing means. In Fig. 1 a horizontal tube 12 is pivoted at one end 13 and carries at the other end a coil 15 which is normally equidistant from two energized coils 18, 19 and receives zero pick-up. When the device is accelerated vertically, the tube is displaced and a signal is generated in the coil 15. This is amplified and passed to the coil 87 of an electromagnet 81 to restore the tube to its original position. A further coil 86 exerts a steady force to counterbalance the pull of gravity on the tube, and this force is adjusted by means of four screws 89a, 89b, which act as magnetic shunts. The tube is partially enclosed in an outer tube 62 and by means of screws 63, 64 it can be tilted so that its physical and inertial axes coincide. Excessive movement is prevented by stops 71, 72. The tube is suspended (see also Fig. 2) from an L-shaped bracket 53, whose vertical lug is U-shaped and passes around the tube, which ends in a floating cross-arm 51. The latter is joined to a similar cross-arm 52 on the U-lug by two flexible connectors 55, 56 which are reduced to a very small thickness at their centres (Fig. 3, not shown) and hence are flexible about a horizontal line which is in the same plane as the axis of the tube. If the device is to measure horizontal forces (Fig. 7), the tube 12 is mounted vertically and the zero adjustment is effected by a screw 110 engaging a nut 111 on the end of the moving coil. The gravity-compensating coil is omitted in this case.

Title: Improvements in or relating to machines for consolidating the surfaces of roads or the like by vibration
IPC: E01C23/02
Filed: 1938-01-21
Abstract: 501,786. Consolidating, smoothing, and grooving road-surfaces. HELD, H., and VOGELE AKT.-GES.. J. Jan. 21, 1938, No. 2125. [Class 107] A machine for consolidating road and like surfaces by vibration comprises a vibrating tool 8 which is given a reciprocating motion in the direction of its length and which comprises two masses 9, 10, loosely coupled together and oscillating in opposition to each other. In the construction shown, the chassis 1 of the machine runs on side rails 3 which serve also to support the outer mass 10. This mass constitutes a housing for the mass 9, and the two masses are coupled together by rubber buffers 11. The tool is elastically suspended from the chassis by wire ,ropes which are connected to cranks 14 mounted on short shafts 12. Arms 15 secured to these shafts are connected by ropes 16 to a windlass 17 whereby the tool may be raised and lowered. The tool is vibrated by an unbalanced weight secured to a shaft 22 which is mounted on the mass 10 and is driven by an engine 4 mounted on the chassis. The engine also drives, through the medium of gearing in a box 5, a connecting rod 25 which imparts the endwise reciprocating movements to the tool. In order to protect the rails, elastic means 18 are arranged beneath the ends of the tool, and other devices may be arranged between the elastic means and the tool in order to tilt the latter. The chassis may carry also a levelling plate 7 which is given an endwise reciprocating motion. In a modification, the vibration of the tool is effected by a connecting rod leading from the shaft 22 to the inner mass 9. The tool may carry projections adapted to bear on a joint-cutting tool for forming grooves in the road surface ; the joint-cutting tool is mounted on a separate chassis which runs on the rails 3.

Filed: 1931-01-24
Abstract: 366,706. Loud-speakers. GRAHAM AMPLION, Ltd., LAURENCE, L. F., and BEARD, J. R., St. Andrew's Works, Slough, Buckinghamshire. Jan. 24, 1931, No. 2421. [Class 40 (iv).] A moving coil loud - speaker comprises a conical diaphragm A to the apex end and on the inner side of which is secured a moving coil C located in the annular gap of a permanent or electromagnet M, the outer surface of which is made conical or conoidal so that it can be arranged within or substantially within the diaphragm. When a permanent magnet is employed, this is formed as a conoidal shell M<1> having a central circular aperture which is so shaped as to be of reduced cross section at the air gap, the shell being formed in one piece with a wall forming a base in which the central polepiece P<1>, which is reduced in diameter near the air gap, is rigidly fixed. The external surface of the shell may be grooved or channelled to avoid air damping of the diaphragm. When an electromagnet is employed, the central pole may be formed in one with a baseplate closing the external shell and the exciting winding is formed with a conical outer surface so as to occupy substantially the whole of the interior of the shell. The coil C is carried by a tubular support T which is centred by a flexible spider carried by a pillar B on the central pole. Alternatively, the pillar B may carry a head of larger diameter than the support T, an external spider being attached to the head and support.

Title: Improvements in self-regulating piston pumps, in particular fuel injection pumps forinternal combustion engines
IPC: F02M59/32
Filed: 1959-01-22
Abstract: 850,151. Fuel injection pumps. BESSIERE, P.E. Jan. 22, 1959 [Jan. 28, 1958], No. 2447/59. Class 102(1). [Also in Group XXIX] A fuel injection pump comprises a piston 3 actuated on its delivery stroke to discharge fuel to the outlet 7, by fuel delivered by a piston 11 past non-return valve 16, this latter delivery also acting on the end of a spring- loaded valve 18 to close a conduit 5 which connects chambers 2 and 4 on either side of the piston 3. On the suction stroke of piston 11 the valve 18 moves to open the conduit 5 and fuel is transferred from the chamber 2 to the pumping chamber 4 as the piston 3 returns under the action of spring 22. The piston 3 is formed with a smaller portion of diameter d and a larger portion of diameter D so that a greater quantity of fuel exists in chamber 2 than can be received into the pumping chamber 4 during the suction stroke. The excess fuel escapes through conduit 9 provided with a throttle 6 which brakes the return movement of piston 3 such that when the engine driving the piston 11 exceeds a predetermined speed the piston 11 starts its delivery stroke and hence actuates piston 3 before this piston has completed its return stroke and thus the quantity of fuel delivered is decreased, the pump thus being self-regulating. The throttle 6 may be adjusted manually or may be adjusted in accordance with the engine speed by a servo-control system (see Group XXIX).

Abstract: 495,087. Converting. URMENYI, L. Jan. 29, 1937, No. 2610. Void. Convention date, Feb. 1, 1936. [Class 38 (ii)] In a converting arrangement comprising a grid-controlled discharge device commutation is effected by means of an auxiliary anode which is connected, at the moment commutation is desired, to a source of voltage through a condenser. In the form shown, an auxiliary electrode 9 is connected through a condenser 10, battery 12 and switch 13 to the star-point of the transformer 2. When the switch 13 is closed the arc transfers to the electrode 9 but as the condenser charges the voltage of the electrode reduces and the arc extinguishes or transfers to the next conducting anode. When the switch 13 is opened the condenser discharges through the resistance 11. In a modification the switch 13 is omitted and the electrode 9 grid controlled. In a further modification the electrode 9 is arranged nearer the cathode than the main anodes and is connected through the condenser 10 either directly or through a battery to the anode to be extinguished, by a rotary switch. In a further modification, each anode is provided with an auxiliary electrode, these electrodes being connected to the condenser through a rotary distributer, either to a battery or to the associated anode. In a modification of this in which each auxiliary electrode is connected to its associated anode through a condenser a battery is connected in parallel with the condenser through a resistance so that the condenser discharges to reduce the voltage on the auxiliary anode.
