Title: Gas valves
Inventor: ROBERTS PETER DEREK
IPC: F23N5/02
Filed: 1987-05-15
Abstract: A gas valve has an operating member made of or coupled to an SME brass component which expands when exposed to a heat source and thus controls a valve member 34. In one embodiment the valve includes a heat conducting member 16 which extends in use between a flame and a coil 10 made of shape memory effective brass which expands rapidly when heated through its transition point so as to displace stem 20 and hold valve 34 in an open position. If the flame fails, the heat conducting member cools, the S.M.E. brass contracts and spring 36 closes the gas valve. In another embodiment an electric resistance heater (48 Fig.2) is arranged to raise the temperature of an S.M.E. brass coil when direct current is applied. <IMAGE>

Title: Electromagnetic injection valve
Inventor: MESENICH GERHARD
IPC: F02M69/08
Filed: 1987-09-14
Abstract: An electromagnetic injection valve especially for fuel in which a valve needle or spherical armature is controlled by an electromagnet comprising an armature (52), guide tube (53) and yoke (46). There is a gap between abutting surfaces of armature guide tube 53 and pole piece abutment 44. With the gap closed and the abutting surfaces lying one on top of the other a certain free cross-section remains permitting uninterrupted fuel flow. Additionally one of the abutting surfaces is flat, the other beveled. These features prevent hydraulic sticking and interruption of flow. Hydrodynamic oscillations in the electromagnetic valve may be reduced by a hose-like elastic damping body within, or embracing, the fuel inflow cross-section, The jacket of the magnetic circuit of the valve may be broken by large area openings to reduce field leakage. <IMAGE>

Title: Gaming and amusement machines
Inventor: CHADWICK NEVILLE DALE
IPC: G07F17/32
Filed: 1988-02-17
Abstract: In a gaming or amusement machine 1 of the kind known as a fruit machine, the 'payout factor' (i.e. the average payout within a period of time during which the machine is played continuously) is altered by a machine control unit 2,5' in accordance with predetermined periods of the day or week. The payout factor may be altered in response to signals from a real-time clock 9' and in-accordance with pre-programmed information stored in the control unit 2, 5'. During predetermined periods of the day or week when the machine is played less frequently the payout factor may be raised, e.g. by increasing the payout ratio, to make the machine more attractive to a player. Conversely, during busy periods the payout factor may be adjusted by decreasing the average duration of a game so that more players can play the machine in a certain time. <IMAGE>

Title: Semiconductor switching device
Inventor: BYATT STEPHEN WILTON
IPC: H01L29/87
Filed: 1988-07-22
Abstract: A semiconductor switching device for use as a remote isolation device (RID) in telephone networks is a two-terminal voltage sensitive circuit comprising two mutually interconnected bipolar transistors (1, 2) with a breakdown diode (3) connected between them so that the circuit switches from an open-circuit condition to short-circuit condition at a fixed breakover voltage, appearing as an open-circuit below the breakover voltage, and appearing as a short-circuit above the breakover voltage. When semiconductor switching devices are installed in a telephone network, they are held in their short-circuit condition network voltage supply and do not affect the normal operation of the network but will switch to their open-circuit condition if the network voltage supply is reduced to below the breakover voltage, and therefore, parts of the network may be isolated from each other, for testing, by reducing the voltage supply. <IMAGE>

IPC: H04M3/00
Filed: 1989-06-16
Abstract: Apparatus for managing a plurality of terminal endpoint identifiers which are to be assigned to terminal equipment units, includes an up-down counter 26 to count the number of the terminal equipment units to which the terminal endpoint identifiers are assigned, a read-only memory 16 which memorizes a first threshold signal and a second threshold signal having a value greater than that of the first threshold signal, and a comparator 25 which compares the count signal with the first threshold signal to produce a coincidence signal when the count signal is coincident with the first threshold signal. On production of the coincidence signal, the terminal equipments to which the terminal endpoint identifiers are assigned are monitored by a central processing unit 13 to judge whether or not the terminal equipments in question are actually connected, the first threshold signal being changed to the second threshold value under the control of the central processing unit in response to the coincidence signal, and the second threshold signal being changed to another threshold signal greater than the value of the second threshold signal, and wherein the central processing unit assigns an idle terminal endpoint identifier to a terminal equipment, issuing an identifier request code without executing a predetermined check routine.

Title: Method of packaging a beverage
Inventor: LYNCH FRANCIS JOSEPH
IPC: B65B31/02
Filed: 1991-06-25
Abstract: A method of packaging a beverage having gas in solution has an open topped container 1 in which is located a hollow insert 5 having a restricted aperture 12. The container is charged with the beverage such as beer 15 so that the aperture 12 is submerged in the beverage and the container is sealed to form a headspace 19 which is pressurised, preferably by dosing with liquid nitrogen. Following sealing the container is rapidly inverted to locate the aperture 12 in the headspace 19 so that gas pressures in the insert chamber 10 and the headspace 19 come into equilibrium. With the fluid contents in equilibrium, or substantially so, the package is reinverted so that gas under pressure in the insert chamber 10 communicates directly by way of the aperture 12 with beer in the chamber 10. Upon opening of the headspace 19 to atmospheric pressure for dispensing the beer a pressure differential is developed by which gas from the insert chamber 10 is initially ejected through the aperture 12 into the beer 15 to effect in the development of a froth on the beer 15. Beer 30 which may flow into the insert chamber 10 prior to the aperture 12 moving to communication with the headspace 19 is accommodated within a well 13 of the insert chamber 10 remote from the aperture 12 to alleviate the ejection of such beer 30 into the beer 15. <IMAGE>
