Patent ZA-813316-B (ZA)
Title: Linear motor
Inventor: KELLY H
IPC: H02K41/035
Filed: 1981-05-18
Abstract: A linear motor comprises an armature and a stator each adapted to provide a sequence of North and South poles along the length of the motor. The pole pitch of the stator magnets is different from that of the armature coils such that with appropriate energization of the coils this difference in pole pitch and stator can result in a net thrust of the armature relative to the stator in a desired direction at any location within a range of relative longitudinal positions of the armature and stator. The motor may be subject to closed loop velocity-and/or positional control and means are disclosed to achieve this. Several variations in pole configurations and means of controlling the coil energization are disclosed.

Title: Cyclone separator
Inventor: BRUCE STUART ROBERT
IPC: A47L9/16
Filed: 2005-07-04
Granted: 2010-07-28
Abstract: A cyclone separator unit comprising a cyclone assembly mounted to a dirt collection receptacle 24. The cyclone separator unit comprises a cyclone chamber 28 and a cyclone outlet tube 32 formed with a number of windows in which a mesh is fitted to provide perforations 31. In use dirt-laden air enters the cyclone chamber 28 via inlet port 30, and is constrained to follow a swirling path so solid particles migrate towards the circumferential wall of the cyclone chamber 28. The air from which the solid particles have been separated is drawn through the perforations in outlet tube 32 and flows upwardly through the outlet tube 32. The solid particles pass into receptacle 24 through opening 37. A secondary airflow is set up between the outlet 37, the interior of the receptacle 24 and the outlet tube 32 without returning to the chamber 28. The secondary airflow assists in transferring the separated dirt and dust into receptacle 24. The cyclone assembly is pivotally mounted to the receptacle 24 to allow the receptacle to be emptied. Other optional elements include filter unit 26, chamber lower wall 34, mesh screen 36 and radially enlarge portion of chamber 29.
