Filed: 1994-08-22
Granted: 1999-12-07
Abstract: A portable air cleaner comprising a cylindrical filter element mounted on a circular base and encased by a cylindrical cover. A centrifugal fan mounted within the cover draws unpurified air into inlet openings disposed in the base and the side wall of the cover, and through the filter element. The resulting purified air is drawn into the centrifugal fan and forced radially outward therefrom.

Title: Method and apparatus for coating three dimensional articles
Inventor: OTANI TATSUO
IPC: B05B12/08
Filed: 1994-04-07
Granted: 2005-09-13
Abstract: A method and apparatus (10) for powder coating three dimen-sional articles (12) carried on a conveyor (14) includes a controller (36) for controlling the rate at which coating material is discharged from a gun (16), so that the rate is proportional to the surface area of the surface portions of the article (12) as they pass the gun (16). Some surface portions topographically have a greater surface area which must be covered, while others are flat or have cut-out regions, requir-ing less coverage or no coverage at all. In powder coating operations, the discharge rate is controlled via automatic or programmed control of an electro-pneumatic air regulator (42) which regulates the supply of pressurized air to a powder pump (24) connected to the spray gun (16). The apparatus (10) assures uniformity in coating for a three dimensional article (12) with multiple surface portions of varying to-pography such as curves, angles, cut outs, etc., while minimizing the amount of wasted coating material.

Title: Diversity path co-channel interference reduction
Inventor: ABU-DAYYA ADNAN
IPC: H04L1/06
Filed: 1996-07-10
Granted: 2003-04-08
Abstract: Diversity path signals, each comprising time division multiplexed symbols in a time slot including known symbols, are combined with respective weights to reduce co-channel interference. Initial weights are determined, using a window on the known symbols, to optimize signal to interference plus noise ratio. These weights are used to determine symbols adjacent the window, and the window is changed to include determined symbols and the weights redetermined. This process is repeated with the window being moved progressively, preferably with successive positions overlapping, throughout the time slot. The initially known symbols can comprise synchronization symbols and/or CDVCC (coded digital verification colour code) symbols. Desirably, both can be used with respective windows being moved in opposite directions through symbols between them to provide two results for each such symbol, the better one of which is selected in dependence upon a monitoring of possibly averaged errors for the symbols.
