Title: A system for separating an entrained liquid component from a gas stream
Inventor: WEST HUGH M
IPC: B01D45/14
Filed: 2002-06-13
Abstract: A system for separating an entrained immiscible liquid component from a gas stream employing a vessel having a wet gas inlet, a gas outlet and a liquid outlet. At least one vortex tube is supported within the vessel and has a liquid outlet end and a wet gas inlet tangential to its sidewall and arranged so that wet gas rotates within the vortex tube to cause the liquid components to be forced against the interior wall surface by centrifugal action. An orifice plate closes the vortex tube first end and has a concentric gas outlet opening therein. A vortex finder tube is axed to the orifice plate in communication with the gas outlet opening and extends concentrically within the vortex tube, the vortex finder tube providing an annular area between itself and the vortex tube internal wall. A gas deflector positioned within the annular area, the gas deflector having a downwardly spiraled surface that diverts wet gas downwardly away from the wet gas inlet. One embodiment may include at least one free-fall preventer within the vortex tube positioned below the tangential inlet and having a plurality of spaced apart radially arranged flow diverting vanes positioned in a plane perpendicular to a longitudinal axis of the vortex tube and serving to augment the rotation of liquid as it traverses towards the outlet end of the vortex tube.

IPC: A01G3/053
Filed: 2004-07-29
Abstract: A handle assembly for a power tool is disclosed, in which the power tool has a housing, a motor provided in the housing and an output shaft adapted to be caused by the motor to execute reciprocating motion. The handle assembly (2, 102) comprise a front handle (6, 106), a rear handle (7, 107) integral with the front handle, and a mounting portion adapted to be mounted to the body of the tool, wherein the front handle defines a first aperture, and the rear handle defines a second aperture larger than the first aperture. By providing a rear handle that forms a continuous loop defining such an aperture, this provides the advantage that the rear handle can be made as large as possible, and therefore positioned as far away from the centre of mass of the power tool as possible, without significantly increasing the overall weight of the power tool, and in particular without unnecessarily increasing the size and weigh of the front handle. This allows a user to apply a torque about the front handle, with as little force to the rear handle as possible.
