Abstract: A radiator comprising two or more radiator sections (1). Adjacent radiator sections (1) are in fluid communication with one another via a coupling (2). The coupling (2) comprises a fluid channel through which fluid is flowable between adjacent radiator sections (1), a liquid sealing gasket (8) for providing a liquid-tight seal around the fluid channel, and a separate gas sealing gasket (9) for providing a gas-tight seal around the liquid sealing gasket (8).

Abstract: A housing is provided for connection between a replaceable lighting unit and a standard lighting unit socket. The housing includes a main body, a holding mechanism for releasably holding a lighting unit and an openable cover for covering a lighting unit held by the holding mechanism. The cover includes a UV filter and the non integral component parts of the housing are held together mechanically without adhesive, such that the housing provides a minimal chemical and UV emission signature.

Abstract: An apparatus for actuating one or more functions on a remote electronic device comprises one or more button members (41) provided within a housing having no electronic components, each button member (41) being associated with at least one fluid channel (45a, 45b). A remote conversion means is also provided which is associated with the or each fluid channel (450, 45b). The or each button member (41) is movable with respect to its at least one fluid channel (450, 45b) to cause an internal pressure change in the fluid channel (450, 45b). The remote conversion means can detect any pressure change in the fluid channels to thereby produce an electrical signal for actuating an appropriate function on the remote electronic device.

Abstract: A pin comprises an inner element and an outer sleeve. The inner element is insertable into and removable from the outer sleeve, and the outer surface of the inner element and the inner surface of the outer sleeve are tapered along at least a part of their lengths.

Abstract: The present invention is an apparatus and method for controlling a process flow rate and a pressure in a vacuum process chamber that is evacuated by a turbomolecular pump. A throttle valve between the pump and the process chamber is controlled to regulate the pressure and flow rate. A backing valve downstream of the pump is also controlled to maintain the setting of the throttle valve within a preferred, stable operating range.

Abstract: The invention relates to an integrated pump apparatus for use in semiconductor processing. The apparatus may include a turbomolecular pump and a dry pump positioned no more than about 20 centimeters away from each other. The turbomolecular pump and dry pump may share at least one of a common housing and a common controller. The apparatus may also include at least one of an abatement device and a cryogenic water pump.

Abstract: A hub (2) includes a spindle (14) which projects through a housing (4) and rotates relative to the housing (4) on a bearing (6) that is located between the spindle (14) and the housing (4). The bearing (6) has two sets of raceways (28,40) that are oblique to the axis x, and in addition rolling elements (36) arranged in two rows between the sets of raceways (28,40). The inner raceways (28) that fit around the spindle (14) and have back faces (32), with the back face (32) for one of the races (26) being against a shoulder (18) from which the spindle (14) projects. Initially, the end of the spindle (14) projects straight beyond the back face (32) of the outer race—indeed, so that the races (26) can be installed over the spindle (14).

Abstract: A hub assembly includes a hub having a spindle with a flange and a shoulder at one end of the spindle and a formed end turned outwardly at the other end of the spindle. In addition, the hub assembly includes a bearing having two cones set end to end and an outer race in the form of a housing located around the cones, and tapered rollers arranged in two rows between the outer race and cones. Initially the formed end of the spindle exists as an axially directed end portion of the spindle. The bearing is installed over this end portion and moved further along the spindle to bring the back face of one of its cones against the shoulder on the flange. The back face of the other cone lies at the end of a spline that leads out to the end portion on the spindle. A coupler ring having exterior and interior splines is installed over the spindle end porotion with its interior spline engaged with the spindle spline.

Abstract: A synchronous transmission system is adapted to carry both synchronous and asynchronous traffic and has a number of nodes providing ingress and egress of the traffic. Each node includes first and second ATM/SDH identifiers whereby the switch can separate the synchronous and asynchronous traffic Separate processing of synchronous and asynchronous traffic is performed at each node.
