Abstract: In a sink-float separation process, e.g. for storage battery scrap, the material to be segregated is fed into a rotary drum containing high-density separation medium and both the sinks and floats are discharged from the drum purely mechanically. Coaxially to the drum (2) containing the medium (5), is a conical drum (4) for the sinks and coaxially within the latter a conical drum (3) for the floats. All the drums are rotationally fixed to tone another.

Patent GB-2060171-A (GB)
Title: A touch sensitive control
IPC: B60L3/02
Filed: 1980-08-06
Abstract: An electric locomotive is provided with a touch sensitive control responsive to signals generated and transmitted through the driver either by the driving gear of the locomotive or by an artificial signal generator and antenna. The driver transmits these signals by hand contact with a touch plate 309 on the locomotive control handle to amplifiers 301 to 303. Amplifiers 301 and 302 have resistive capacitive circuits to effectively exclude unwanted signals and circuit 331 provides a threshold. A further amplifier (Fig. 3 B1) connected to amplifier 303 controls a relay through a transistor, which in turn controls an emergency brake. Providing a signal of the requisite frequency is present at touch plate 309 the brake is held off, but not otherwise. If the driver removes his hand from the control handle the transmission link is broken and no signal is present at the plate 309. A resistive capacitive time delay circuit connected to the input of the further amplifier delays operation of the brake and disconnection of the propulsion mechanism from the driving wheels for a predetermined period the duration of which is pre-set by a variable resistor and provision is made for preventing release of the brake after operation until a requisite signal is present at plate 309 for more than a predetermined minimum period. <IMAGE>

Abstract: A clutch release mechanism in which a clutch release fork (14) forms part of a closed bar linkage (22), (23) and (14) for converting rotary movement of a clutch actuating shaft (27) in one direction (clockwise) into substantially axially linear motion of the release fork end for operation of the release bearing assembly (11), and rotary motion in the other direction (anti-clockwise) into transverse motion of the fork (14) to retract the fork (14) from engagement with the bearing assembly. The closed bar linkage is shown as a three bar linkage but in another embodiment is a four bar linkage. <IMAGE>
Patent GB-2082651-A (GB)
Title: Method and apparatus for the control of fluid flow
IPC: E21B34/00
Filed: 1980-08-28
Abstract: In methods for controlling fluid flow, a pressure-actuated main valve (57) is conditioned to operate by fluid pressure actuation of a pilot valve (84) which closes a fluid flow passage (78) through the main valve so that the main valve may then be actuated by fluid pressure. Apparatus for carrying out the method comprises a self-piloting check valve apparatus, (disclosed in three embodiments) wherein dual valves are provided. One of the valves serves as a pilot valve and is shown in the form of a spring-biased check valve (84), closing of which permits closing of a main ball valve (57) adapted to withstand highly elevated pressures. The sealing elements of the valve are fully protected during flow periods whereby fluid erosion is prevented. Full opening low passages (78) are provided through the valves in each embodiment of the apparatus. <IMAGE>

Filed: 1980-10-01
Abstract: In a data transfer system an interface unit (17) has a fibre optic path (18) to a star point (20) access coupled (14) to a bi-directional data highway (10). The path (18) leads to a transmitting transducer (32) and a receiving transducer (31) which interface via a control circuit (34) with data input 35 and output 36. Reception of a signal on the highway (10) further triggers the control circuit (34) to constructively transmit to reinforce signals on the highway (10). <IMAGE>
Patent GB-2086591-A (GB)
Title: A periodic averaging correlator
IPC: G01R29/00
Filed: 1980-10-23
Abstract: The correlator is arranged to establish when the time constant of a repetitive time-varying function x(t) reaches a predetermined level in response to variations in one of the factors of the function x(t).   The correlator includes an integrator (16) and an analogue store (24) for periodically sampling and storing the output level of the integrator. A switching assembly (6) is switched by a control circuit (28) to correlate the function x(t) with a function y(t) by feeding in succession to the integrator the sum of the time varying function x(t) and the stored voltage level, and the sum of the inverted time-varying function x(t) and the stored voltage level. The achievement of a peak in the stored voltage level will indicate when the time constant function x(t) reaches the predetermined level. By repeated operation of the switching assembly an averaging action takes place so as to eliminate noise. In addition the level of the stored signal at its peak value will be directly proportional to the amplitude of the function x(t). <IMAGE>

Title: Devices for securing and clamping rubber blankets
IPC: B41F30/04
Filed: 1982-03-25
Abstract: A clamping shaft (6), formed as a hollow shaft, is rotatably mounted in a bore (2) disposed in a cylinder (1). In the cavity of the clamping shaft (6) two gripping shafts (11) are disposed at a distance from one another and are held at both ends in bearing members (12) such that they may rotate and are freely movable with respect to one another. Each bearing member (12) is slidably guided on a pin, which is mounted transverse to the clamping shaft (6), and is urged towards a passage or aperture in the clamping shaft (6) by means of a compression spring. The wall of the cavity of the clamping shaft (6) thus brings about the clamping of the ends of the rubber blanket (15) between the two gripping shafts (11). Rotation of the shaft after clamping of the ends tensions the blanket. <IMAGE>

Title: Electric circuit incorporating safety means
Inventor: WALTON COLIN ROBERT GEORGE
IPC: H01H47/00
Filed: 1982-07-15
Abstract: A relay, such as a reed relay, having a solenoid (17) and a mechanical switch (15) permits electricity from a point (20) to flow through a load (10). Safety means is provided to prevent trouble if the switch (15) should fail to open. The safety means comprises an electronic switch in the form of a thyristor (30) in series with the mechanical switch (15), the load (10) being connected to a terminal (11) between the switches. A control transistor (22) renders the thyristor (30) non-conductive when a current passes through the solenoid (17), and renders it conductive when no current passes through the solenoid. If the mechanical switch (15) fails to open when the current through the solenoid ceases, a current passes through the thyristor (30) causing a fuse (16) to blow. In the absence of a fuse the potential across the load (10) may be reduced to an acceptable level. <IMAGE>
