Title: Method of separating a particle mixture using a biphasic system
Inventor: TORRECILLA JAUREGI PAULA
IPC: B01D21/00
Filed: 2000-06-28
Abstract: A method of separating a particle mixture comprising first and second types of particle which differ chemically from each other, using a biphasic fluid system comprising a relatively dense first fluid and a relatively less dense second fluid, said fluids being substantially insoluble in each other. The particles PM to be separated and the two fluids are introduced into a separation chamber 10; the content of said chamber is allowed to settle to form an interface between said fluids; particles at the bulk interface are separated from particles near the bottom of the separation chamber - part of the settled material is discharged from 10 as a first stream H1 (denser fluid enriched with second-type of particles) into separation chamber 20, part of inter-phase material discharged as second stream L1 (less dense fluid enriched with first-type of particles) into separation chamber 30. The method is characterised in that: <UL ST="-"> <LI>at least the first fluid is a liquid; <LI>each particle can be found at the interface between said fluids in the absence of said other particle; <LI>the amount of particle mixture introduced into the separation chamber is chosen such that the ratio between the surface area of an interface formed when only the two fluids are present in the separation chamber while at rest and the smallest area occupied by the particles while in contact with a flat surface is   &   1. </UL>

IPC: H01H13/56
Filed: 2000-08-07
Abstract: An operating mechanism comprises an operating member 4 which is coupled to the trip lever 3 of a steam sensor switch 2 and an actuator 10 for moving the operating member 4. The actuator 10 is movable transversely to the operating member and has an end portion which, when the actuator is depressed, moves into an aperture 6 in the operating member 4 where cams on the actuator co-operate with cam follower surfaces of the aperture 6. On one side of the aperture the cam on the actuator 10 is a simple inclined surface 13 for moving the operating member 4 in a first direction and on the other side of the actuator the cam is a pivotally mounted member 14 which is compliant for accommodating movement of the operating member 4 in the first direction but has only limited pivotal movement in the opposite direction. A first depression of the actuator 10 brings one of the cams into play to move the operating member 4 in a first direction and a second depression causes the other cam to come into play to move the operating member 4 back in the opposite direction.

Title: Self-levelling projector for use with power tools
Inventor: BONE DANIEL
IPC: G01C15/00
Filed: 2001-12-14
Abstract: The device is for projecting an alignment guide (34,36) onto a workpiece, such as a wall to have holes drilled in. It comprises a mount (2) for mounting the device on or upon the wall, by fitting into a pre-drilled hole in the wall, and a self levelling projector such as laser (12) for projecting the alignment guide (34,36), which can be a beam or plane of red light, in a predetermined orientation relative to the vertical. Extra holes can then be drilled in a straight line with reference to the original hole using the alignment guide. The laser (12) is articulated to the mount (2) so that the alignment guide (34,36) emanates from that point on the workpiece where the mount (2) is situated and the device is oriented in a vertical position by means of ball race (8) which allows for free rotation between plastics disc (4) and retaining member (6). The gravitational force of battery (18) causes a pendulum action and results in the mounting bracket (16) coming to rest in a vertical axis. A gimbal mechanism (see Fig 6) can also be used as a self levelling mechanism to allow for the original mounting hole not being straight. The device may form part of a kit of parts which includes an electric drill (Fig 5, 28).

Title: Integrated circuit with multi-plate capacitor having lowest plate connected to a virtual ground node
Inventor: LAWS PETER GRAHAM
IPC: H01L23/522

Abstract: An integrated circuit comprises a substrate (1) and a multi-plate capacitor having at least three plates (3,4,7), where the multi-plate capacitor is composed of two capacitors where one plate (4) is shared by both capacitors. The plate closest to the substrate (3) is connected to a virtual ground node Vgnd which may be insulated from substrate (1) by dielectric layer (2). The virtual ground node Vgnd is at constant voltage and therefore parasitic losses through coupling to substrate (1) are minimised. The central plate (4) may be connected to a control element such as a variable capacitance diode or a switch which may be a field effect transistor. The integrated circuit may be a frequency selective LC circuit comprising an inductor (11) with parallel capacitors (10,20,21, Fig. 4), and therefore may act as a filter or be used as a radio tuner.

Title: A system for controlling a purge time cycle and a fill time cycle of an emission control device.
Inventor: MEYER GARTH M
IPC: F01N13/02
Filed: 2002-06-05
Abstract: A system for controlling a purge time cycle and a fill time cycle of an emission control device that receives exhaust gasses generated by an internal combustion engine, the device being filled with a constituent gas from the exhaust during a first engine operating condition and purged during a second operating condition, comprises open loop cyclical fill and purge times being initially determined from a set of predetermined values as a function of the engine operating condition with the device being adapted to periodically determine a first value representative of the total device capacity at a given time and a second value representative of the quantity of oxygen stored in the device at the same time and then adjust at least one of the cyclical fill and purge times as a function of the first and second values. A third value, representative of the oxygen concentration present in the exhaust gasses flowing through the device may also be generated. If the third value is less than a reference value an adaptation value, which may be a function of the length of time the third value exceeds this reference value, may be generated. In use, the vehicle emission control device, and a control system therefore, initially work from a baseline set of parameters but these are modified in use to take into account actual engine/exhaust system wear and performance as the vehicle ages and the control system notifies the user when the exhaust catalytic system needs to be regenerated and/or replaced.
