Title: Device for loading a skip or container onto a vehicle
Inventor: CHAPLIN NEALE ALISTAIR
IPC: B60P1/64
Filed: 1983-01-17
Abstract: The device comprises an L-shaped member (11). A slide (12, 13) is pivotable about a first transverse axis (24) intermediate the ends of the vehicle and about a second transverse axis (27) adjacent to the rear of the vehicle. The slide slidably supports a rearwardly extending arm 16 and a ram is provided for sliding the L-shaped member between a forward and a rearward position. Two rams (29) are provided for pivoting the side and thereby the L-shaped member about the axis (24) when the L-shaped member is in the rearward position to unload the skip or container from the vehicle. Retractable means (34, 35) are pivotably mounted on the slide and are movable by rams (36) between a skip or container engageable position and a retracted position. When engaged with the skip or container with the latter intermediate its forward and rearward positions operation of the rams (29) cause the slide to pivot about its axis (27) so that the skip or container is tipped thereby and the contents do not foul or damage the rear of the vehicle. <IMAGE>

Title: Vapour pressure control
Inventor: EVANS ANTHONY CYRIL
IPC: H01J37/32
Filed: 1985-09-04
Abstract: Vapour pressure in a chamber (1) e.g. a plasma chamber is controlled by adjusting the heat applied to a supply of solid material from which the vapour is produced. An error signal responsive to the pressure in the chamber (1) controls the operation of a heater (4) which either heats a supply (5) of solid material which is fed directly to the chamber (1), or (Figure 2) heats a restriction defined by said solid material in a conduit leading from a further supply of solid material. The error signal can be generated from the supply voltage of a current regulated power supply (6) applied to electrodes in the chamber and compared with a reference voltage (3). The material may be iodine for use in etching semiconductor compounds. <IMAGE>

Title: Breaking pressure control unit
Inventor: REINARTZ HANS-DIETER
IPC: B60T11/34
Filed: 1985-11-15
Abstract: A braking pressure control unit with a closure member, comprising a closure portion and a shaft portion, movable along an axis relative to a valve seat to control fluid flow through the valve seat opening. The closure member (22) and the shaft portion (24) are undetachably interconnected by e.g. soldering or friction-welding to facilitate ease of manufacture and assembly. In one embodiment the unit has a closure sleeve (5) which can be inserted into a housing (1) of a braking pressure generator and which incorporates a first valve assembly (21, 22) for the braking pressure control and a second valve assembly (16) to act as a non-return valve. The first valve assembly (21, 22) comprises, as a closure member, a control piston (23) slidable pressure-responsively in opposition to the force of a control spring (25) and including a closure portion (22) which cooperates with a valve seat (21) provided in a second sleeve (12) which latter is displaceable in the first sleeve (5). Owing to the slidability of the second sleeve (12), there results a reduction of the outlet pressure which commences almost simultaneously with the reduction of the inlet pressure. Due to the arrangement of the valve seat (21) at a component movable separately from the first sleeve (5), materials may be chosen for the first valve assembly (21, 22) which ensure optimum tightness and, simultaneously, insusceptibility to brake fluid and high temperatures. <IMAGE>

Title: Speed control of A.C. motors
Inventor: FOX ALISTAIR MORLEY
IPC: H02P27/04
Filed: 1985-12-19
Abstract: A variable speed motor control system eg for an overhead crane or hoist comprises a pair of two- position switches 7 each of which can be manually actuated so as to switch from a normal state to either one of two actuated states and which assumes the normal state automatically when the switch is released. A control circuit 6 is responsive to actuation of the switch to apply inputs to an inverter 3 which inputs control the motor speed. The control circuit is responsive to actuation of the switch to a first one of the actuated states to accelerate the motor 1 to and thereafter maintain the motor at a predetermined minimum speed, or, where the motor speed is already at or above the predetermined minimum speed when the switch is actuated to the first actuated state, to maintain the motor speed constant. The control circuit is responsive to actuation of the switch to the second actuated state to accelerate the motor, and is responsive to the switch assuming its normal state to decelerate the motor to rest. The control system may be connected between a standard variable frequency or other drive and an operator's pendant. The pair of two-position switches can be provided in a single pendant so as to provide variable speed operation in two directions. <IMAGE>
