Patent GB-2256726-A (GB)
Title: Dispensing gas-containing beverages
Inventor: FREESTON MICHAEL RICHARD
IPC: B67D1/14
Filed: 1992-06-12
Abstract: An apparatus for dispensing beverages such as lager beers has an inlet passage, the flow along which is controlled by a valve, leading to an outlet passage 14 which has two branches 12, 13 both loading to a dispensing point. One branch is substantially unrestricted but the other branch, through which a minor proportion of 1 the beverage flows, incorporates a restrictor 15. The restrictor acts to provide the required degree of frothing. Branch 13 reduces a small amount initially and then gradually widens. This is to control turbulence in the liquid flow and reduce the speed of flow respectively. The outlet of branch 13 is slightly beyond that of branch 12 so that the two flows combine smoothly at the dispensing point. <IMAGE>

Title: Process for chromatographic separation
Inventor: MASUDA TAKAYUKI
IPC: G01N30/58
Filed: 1992-06-12
Abstract: A series of packed beds 1-8 linked in a circuit and provided with appropriate valves is used in a cyclic process to separate two or more components of a sample. In a first step, Fig. 3 (1-1), a separation cycle is interrupted by closing valve 9 when bed 5 contains some slower component B1 together with the tail of the faster component A. Fresh mixture "f" is then added to bed 5 downstream of valve 9 and, simultaneously, a desorbent "D" is added via valve 1d to the upstream side of bed 1 and so to elute slower component B1 through valve 4b. In a second stage the faster component A is eluted during circulation of fluid by adding desorbent "D" through valve 2d and withdrawing A via valve 7a - Fig. 3 (2-1). As the chromatogram develops, the prints of addition of desorbent and withdrawal of component A move stepwise along the beds (Fig. 3 (2-2) to (2-5), not shown). The method is illustrated for saccharides and may be adapted for more than two components. <IMAGE>

Patent GB-2273319-A (GB)
Title: Fuel injection pump.
Inventor: THOMAS GERALD SYDNEY
IPC: F02M59/46
Filed: 1993-11-22
Abstract: A spill valve for a fuel injection pump includes a valve member (23) movable towards a seating (24) to prevent spillage of fuel via a passage (25) from the pumping chamber of a fuel injection pump. The valve member is actuated by a piston (26) against which fluid pressure can be applied via a passage (32), a restrictor (33A) and a chamber (29) to close the valve member onto the seating (24). The movement of the valve member away from the seating is initiated by the opening of a valve (21) to lower the pressure in the chamber (29). When the pressure in the pumping chamber is low, e.g. during the pre-delivery phase of the injection pump, movement of the valve member (23) is limited by a stop member (28) but this can move to allow increased movement of the valve member when fuel at high pressure is spilled from the injection pump through the passage (25).   <IMAGE>

Title: Tissue characterisation using intravascular echoscopy
Inventor: WILSON LAURENCE SYDNEY
IPC: G01S15/89
Filed: 1994-04-18
Abstract: Calcification of an artery wall and the presence of degenerative plaque on an artery are two symptoms of arterial disease. Ultrasonic echoscopy is used to monitor the presence of calcification of an artery wall. An intravascular transducer (10) at a location within an artery (15) is used to obtain frames of ultrasound during at least on cardiac cycle of a subject. The ultrasound data obtained is processed to produce an indication of the elasticity of the artery wall (12), namely the average fractional deformation of each region of the arterial tissue. This "elasticity" data is displayed simultaneously with an image of the artery wall. The presence of degenerative plaque is determined using intravascular echoscopy and monitoring the frequency content of echoes produced by backscatter from the tissue in the artery wall. <IMAGE>

Title: Controlling evaporated fuel purge device for engine.
Inventor: KAWASAKI TAKAO
IPC: F02D45/00
Filed: 1996-03-12
Abstract: Based upon the running condition of the engine 1, the air-fuel ratio of the fuel mixture supplied to the engine is controlled by open loop control to a target air-fuel ratio. The purge device includes a canister 22 which adsorbs evaporated fuel from the fuel tank 20, and a purge conduit 24 which supplies a purge gas (a mixture of the adsorbed fuel and air) to the engine 1 in a predetermined running condition. The purge gas flow rate is changed according to change in the target air-fuel ratio by controlling the flow rate through the purge conduit 24 according to the proportion between the target air-fuel ratio and a predetermined value. The predetermined value is determined by measuring the amount of fuel supplied to the engine when it is operated in a feedback mode. By doing this, deviations in air-fuel ratio precipitated by purging are eliminated.

Title: Electric power supply for vehicle; heating catalytic converters
Inventor: TANIGUCHI MAKOTO
IPC: H02K11/04
Filed: 1996-05-10
Abstract: The vehicle power supply has an alternator 10 which charges a battery Ba, switches 41, 42 for connecting the alternator output selectively to a low voltage load 50 and battery Ba or to a high voltage load 60, the switches 41, 42 being disposed in a housing 10a of the alternator 10. The high voltage load 60 may be a windshield heater, or particularly a catalytic converter which is energised by the high voltage for a while after the engine is started. The alternator housing 10a also accommodates a microcomputer 70 which controls switches 41, 42 and regulates the alternator output at 28 volts initially for energising the catalytic converter, and thereafter at 14 volts. The switches 41, 41 may be SiC-MOSFETs having a high resistance in series with a parasitic diode (Figs.2,7). A rectifier unit 30, the switches 41, 42 and the microcomputer 70 have cooling fins (Pa, Pb, 40a, 70a, Fig.3). In an alternative arrangement, a rectifier unit for the high voltage load has a low-side half-bridge formed by diodes and a high-side half-bridge formed by SiC-MOSFETS (81, 82, 83, Fig.6) which are sequentially pulse width modulated by microcomputer 70. Further SiC-MOSFETS (37,38,39, Fig. 14) may provide a high-side half-bridge for the low voltage load and are also sequentially pulse width modulated so that the alternator may then power the low voltage load simultaneously with the high voltage load. The low-side half-bridge may have SiC diodes requiring no cooling.

Title: Hop Harvester
Inventor: PEERS ROBIN
IPC: A01D46/02
Filed: 1996-09-09
Abstract: A hop harvester has a chassis (1) that straddles a row of dwarf hops. It carries stripper units (2) that engage opposite sides of the row. Sensors (8) also engage these opposite sides and respond when the stripper units (2) go out of symmetry with respect to the row. These units may float laterally with respect to the chassis (1) and the sensor response can be used to shift them back towards symmetry, while the driver of the harvester also steers towards that ideal. Alternatively the stripper units (2) may be effectively rigid with the chassis, and the sensor response can be used to govern some or all of the steering to maintain symmetry.

Abstract: A virtual non-thermionic cathode, e.g. for a flat panel electron beam display, as the position of a space charge cloud associated with it fixed by the geometry of a fixed insulating layer 402. The layer 402 can be made to accurate dimensions and hence the cathode 404 to control grid 406 dimension can be accurately controlled and will not change as a result of any mechanical, electrical or physical changes in the construction. The fixed insulating layer 402 is located on a surface of the control grid 406 facing the cathode 404. A space charge layer is built up on the surface of the insulating layer 402 facing the cathode 404, and thus emission from the cathode 404 is stabilised.
