Title: Flow control sytem for a pipe network
Inventor: MALHAM KEVIN SHAUN
IPC: E03B7/00
Filed: 1995-09-15
Abstract: A system for monitoring and controlling the flow of water within a pipe network in a building to limit damage caused by leakage comprises a plurality normally open flow control valves within the network and manual switch means remote them which is operable to drive the valves closed. The valves are locatable within individual pipes of the network and are electrically drivable closed and manually resettable. One or more manual switches may provided at different locations spaced from the valves and each valve may be closed by the any of the switches. To provide protection when the building is unoccupied each valve has an associated flow sensor and the system provides that the output of any sensor may cause its associated valve and any or all of the valves to be closed. In one described arrangement the outputs of the sensors input to an OR gate the output of which forms one input to a two-input AND gate the other input to the AND gate being taken from a switch settable by a user. The output of the AND gate drives the valves closed. Another described arrangement provides the outputs of the sensors form first inputs to individually associated two input AND gates the second inputs to which are provided by a switch settable by a user, and that the output of each AND gate is used to control operation of the valve individually associated therewith. An LED display indicates that the system has functioned.

Title: Beverage packaging method and apparatus
Inventor: REYNOLDS ANDREW JOHN
IPC: B65D79/00
Filed: 1994-03-31
Abstract: Method and apparatus is described for removing oxygen from a can (12) and frothy head inducing capsule (10) of a lightweight two piece can beverage pack storing alcoholic beverage under gaseous pressure. The method involves evacuating the can and the capsule combination and purging with an inert gas such as Nitrogen and retaining the purged condition of the capsule and of the can by filling the can with water. Just before the can is to be filled the can is inverted to pour the water away and is washed in a conventional manner and reinverted ready for filling. The method may be automated by marshalling cans on a conveyor and purging a large number of cans simultaneously in a batch first of all to the evacuation, then the purging step and then the water filling step. Two batch purging units (94, 96) may be provided and operated out of synchronism to provide a continuous supply of purged cans partly filled with water ready for feeding to the can washing (56) and filling (64) facility. Alternative apparatus involves injecting Nitrogen gas in liquid or gaseous form into the capsule before or after it is inserted into the can and plugging the hole made by the filling device (24) so as to retain the gas charge within the capsule. <IMAGE>

Title: Vehicle safety system switching arrangement
Inventor: DARRABA ROGER
IPC: B60R21/01
Filed: 1998-01-29
Abstract: In a vehicle safety system, a plurality of safety devices are each associated with a resistor (93) forming a squib associated with an explosive deployment charge. Each charge may be deployed by activation of a control unit (94) responsive to the conditions sensed by the sensors (95,96). The wiring arrangement of the deployment devices is such that each device needs the operation of two switches (one each from group 90 and 91) to be activated. All devices either share a common switch at one of their ends (figure 2) or form a matrix array. Preferably the devices are pyrotechnic explosives but they may also be solenoid activated. They are used for deploying crash-bags (airbag), seat-belt pre-tensioners and the like in the event of a vehicle accident. The advantage is a reduction in the number of switches needed to control the deployment of a multiple collection of safety deployment devices.

Title: Reevaluation of a Boolean function applicable to event driven transaction processing
Inventor: MUNDY PAUL
IPC: G06F7/00
Filed: 1998-10-16
Abstract: A method, apparatus and computer program product reevaluates a Boolean function such as may arise as triggering events in the data processing of long running business transactions. The Boolean function consists of multiple groups of component Boolean functions which may be represented as respective nodes in a hierarchy and whose inputs may be externally input Boolean values or the Boolean values of other groups lower in the hierarchy, the current values of each of the groups and of the overall function being known in advance. The method stores for each group its current value then, in response to a change of any external input, reevaluates the value of any group to which the external input is applied. If the group value has changed, the reevaluation is repeated for any present group receiving that group value as input until the value of the respective group does not change or until there is no parent group. In this way, the overall value of the Boolean function may be reevaluated without a total recalculation.
