Title: Pressurisation of a container prior to filling with beverage
Inventor: JONES MICHAEL EDWARD
IPC: B65B31/04
Filed: 1991-10-08
Abstract: A method of and apparatus for packaging a beverage in a container 1 having a primary chamber and a relatively smaller secondary chamber which communicates with the primary chamber by way of a restricted orifice has the exterior of the container maintained at atmospheric pressure. The container such as a can 1 to be charged with beer is engaged within a filling head block 24 through nozzles 35 from which beer 9 is to flow into the can 1 from a bowl 8. Prior to filling the can 1 is pressurised through the head 24 with nitrogen gas to greater than atmospheric pressure and subsequently evacuated to atmospheric pressure by control of valves 32, 33. Such pressurisation and evacuation may be repeated sequentially to dilute the atmospheric oxygen content within the primary and secondary chambers of the can 1 where the oxygen has negligible effect on the beer which is to be sold in the can. A gas exchange conduit 40 extends between the bowl headspace 12 and the can 1. Conduit 40 has a port 41 of a gas control valve 55 which port 41 is closable by movement of lever 60. A beer flow valve 37/46 controls flow of beer 9 from the bowl through nozzles 35. During pressurisation of the can 1 with nitrogen gas the lever 60 is adjusted to maintain closed the port 41 of the gas flow valve and the beer flow valve 37/46 to ensure that high pressure gas in the can 1 cannot flow by way of the gas exchange conduit 40 into the bowl headspace 12 and again flow through the nozzles 35 into the beer 9 in the bowl 8. <IMAGE>

Patent GB-2271863-A (GB)
Title: Power window safety device
Inventor: TAKEDA HITOSHI
IPC: E05F15/16
Filed: 1993-07-16
Abstract: A power window has a safety device which stops and reverses the closing operation of the window in response to the detection of an object-caught state by detecting a reduction in the speed of window movement. The opening/closing position of the window and its speed are detected by counting pulses generated as the window moves. Safety control is carried out over a region of window openings based on its detected position, but when the window reaches a position near to fully closed the safety control is disabled so that the speed reduction on closure does not result in reversal of the window movement. At the near closed position, the count indicative of the opening/closing position is also reset to ensure the position indicated by the counter reflects the actual position of the window. <IMAGE>

Title: Magnetic antenna system having independently controllable electrical field shielding and magnetic field balance
Inventor: CORDERY ROBERT ARTHUR
IPC: H01Q7/04
Filed: 1994-02-28
Abstract: A magnetic antenna system particularly useable in electronic article surveillance systems for detecting the presence of a resonant tag utilizes multiple loop shielded transmitting and receiving antennas (12, 14). The antennas employ shield structures (28 - 38) that are designed to minimize the electric field response and to provide a balanced magnetic field response. The shield has an open circuit along its length and balancing conductors (40, 42) connected across the open circuit at appropriate locations to tend to balance the magnetic response of the antenna. The magnetic field responses of different ones of the loops (16, 22; 50, 52) in each of the antennas are different, and the loops are oriented so that more responsive loops of the transmitting antenna are positioned opposite less responsive loops of the receiving antenna, and vice versa, in order to reduce the coupling between antennas without reducing the sensitivity of the receiving antenna to a tag signal. <IMAGE>

Title: Valve for pressure line of spring applied brakes
Inventor: POWNALL COLIN STEPHEN
IPC: B60R25/08
Filed: 1994-10-05
Abstract: A valve comprises an inlet port 11, an outlet port 12 and an exhaust port 13. Valve member 15 is biased towards a seat 14 by spring 21 and valve member 17 is biassed towards seat 16 by spring 22. Valve members 15 and 17 are coupled to move in unison between a first position (figure 1) and a second position (figure 2). When no pressure is applied to port 11 a solenoid 20 will, when energised, move the valve from its second position to its first position, and de-energising the solenoid will return the valve to its second position since spring 21 applies a greater force than spring 22. When fluid pressure is applied to port 11 the pressure forces exerted on the valve members is such that changing the status of solenoid 20 will not change the status of the valve until the fluid pressure is released. <IMAGE>
