Title: A storage system for a volatile liquid
Inventor: CHUNG KIM LEONG
IPC: B67D7/04
Filed: 1983-05-06
Abstract: A storage system for a volatile liquid includes a storage tank (1) for the volatile liquid and a reservoir (4) for vapour derived from the volatile liquid. During supply of volatile liquid to the tank (1), vapour in the tank (1) is transferred via conduits (7-9) for storage under pressure in the reservoir (4). During withdrawal of volatile liquid from the tank (1), the vapour in the reservoir (4) is transferred back to the storage tank (1) through an expansion tank (5) via further conduits (10-12). The vapour is thus kept in a closed circuit and evaporation losses are minimised. <IMAGE>

Filed: 1984-04-19
Abstract: A box-like tray 25 holds a stack 27 of more than 1,000 sheets of paper and is positioned so that extension (28) is received in the paper-receiving slot 22 of a photocopy machine 20. Independently driven sheet-separator 29 rides on top of the stack 27 and feeds the top sheet to an independent feed- drive mechanism 30 which advances the sheet onto a teetering paper-receiving tray 31, the discharge end of which is positioned within the machine 20 beneath the copier sheet-take-away roller 23. A cam mechanism causes the discharge end of the tray 31 to press the leading edge of the sheet against the take-away roller 23, and, when the copier 20 is actuated and the sheet is drawn into the copier 20, a sensing finger 67 located on the tray 31 detects the passage of the sheet and actuates the drive motors 44, 54 for the sheet separator 29 and the feed rollers 47, 48 to advance the next top sheet of the stack onto the tray 31 as before. <IMAGE>

Title: Adaptable remote control interface
Inventor: PATFIELD KEVIN MICHAEL
IPC: G11B15/02
Filed: 1984-10-22
Abstract: A control interface for connection between a computer and a video recorder to be controlled by the computer. The computer has an input port (10) connected to a cable assembly via a multi-way plug and socket (11). By selectively earthing a number of bits of the input port via wire links (12) the cable assembly presents a unique type code to the computer from which the latter can determine which cable and hence which video recorder is connected. The cable also serves to connect output switches (13) within the computer to the video recorder remote control. The latter may be of 3 types and changing the cable serves to adapt the system to either a resistor array (Fig. 1), an infra-red link or a parallel interface. <IMAGE>

Title: Fluid control valve
Inventor: URBANI PAUL VALENTINE
IPC: F16K31/22
Filed: 1984-11-28
Abstract: The invention provides a fluid control valve in which a biassing means such as a float 10 urges the valve 4 to the open or closed position, depending on the application of the valve, and is normally overridden by a restraining means 13, 14, the valve further including a control 16-19 by means of which the effect of the restraining means can be broken so that the biassing means can open or close the valve. The restraining means may be a magnet which holds the valve open or closed against the force of the float until its hold is forcibly broken by the control. The control may be pneumatic and may be operated remotely from the valve eg when used in a cistern, it may be operated by opening a door or by a floor pressure plate. <IMAGE>

Title: Hydro-pneumatic suspension device with adjustable valve
Inventor: MUTO TOSHIAKI
IPC: B60G17/08
Filed: 1984-12-19
Abstract: A hydro-pneumatic suspension device for a vehicle comprises an extendable and contractible suspension main body 1,5 having a variable volume liquid chamber R2, R3 therein, an accumulator 2 having a variable volume liquid chamber R1, a liquid passage 3 connecting the variable volume liquid chambers in the suspension main body and the accumulator, and a damping force generating mechanism 4, and Fig. 3, provided in the liquid passage and having a rotary shutter 28 for selectively opening a plurality of orifice passages 37, 38 thereby changing the effective area of the passage. The opposite ends 28a, 28b of a shaft rotatably supporting the rotary shutter extend respectively outside of the liquid passage and have equal areas exposed to atmospheric pressure. Virtually no axial force is therefore extend on the shutter by the liquid pressure within the device. This means that the power of the actuator 46 for rotating the shutter can be reduced. The shutter 28 is made up of two cylindrical parts 26, 27 rigidly interconnected. The flow path adjusted by the shutter bypasses the damping valves 21, 22. A check valve 36 gives a differential flow through the bypass. <IMAGE>
