Patent CA-2255516-A1 (CA)
Inventor: TUNG EDWIN
IPC: H01Q21/26
Filed: 1998-12-11
Abstract: A multiport beamforming antenna provides multidirectional beam patterns with minimum interference comprising multiple, as for example twelve, radiating elements mounted on a conducting ground plane. Multiple, for example six, reflecting surfaces, each having a shape of one quarter of a circle or an ellipse, are radially disposed about the center of a round ground plane conductor to give a hemispherical shape with multiple, for example six, equal sectors. Each sector of the multiport antenna contains two types of radiating elements mounted adjacent to the corner of the reflector. The first elemental antenna is responsive to energy having a first polarization, while the second elemental antenna is responsive to energy having a polarization orthogonal to the first polarization. With such an arrangement, all the radiating elements are located in close proximity without coupling signals to each other, and each element is capable of producing a directional radiation pattern in an independent manner. Consequently, the physical area required to install the antenna is minimized, and the antenna provides very good hemispherical coverage and for example may be placed anywhere on the ceiling of a room to provide coverage of the entire room. A method of processing signals received by the multiport antenna is also disclosed.

IPC: F04D7/06
Filed: 1997-06-18
Abstract: An apparatus for removing bottom dross from molten zinc (11) contained in a coating pot (10) includes a pump (22), a traversing carriage (16) for positioning the inlet of the pump in a desired horizontal location and a slide mechanism (18) for positioning the inlet of the pump in a desired vertical location. The pump is moved in horizontal and vertical direction to remove the accumulated bottom dross. The bottom dross contained in molten zinc is pumped into a V-shaped channel (39) and allowed to flow into either a removable basket (51) or into a pre-melt pot (53). The pump of the present invention is a pedestal, centrifugal graphite pump powered by an air motor. The pump has a housing enclosing an impeller. The distance between the impeller and the inner wall of the housing is sufficiently large to avoid plugging by the bottom dross but sufficiently small to permit pumping.

Title: Electric cooking oven with infrared gas broiler
Inventor: ADAMS CARL H
IPC: A47J37/06
Filed: 1999-03-31
Abstract: A cooking oven having an electric heating element in the bottom for baking, warming and high temperature-self cleaning, and an infrared gas broiler in the top of the oven. The infrared gas broiler is supplied with a fuel gas/air mixture from a venturi tube that uses the stream of fuel gas to draw clean air into the oven from outside the oven. A  flue duct is provided in the top rear of the oven for the discharge of the combusted gases but no other opening is provided, such as for secondary air that is normally required for a gas oven.  The venturi tube assembly creates a fuel gas/air mixture that contains 100% of the air necessary for full combustion of that gas and a positive pressure for distributing the gas/air mixture through ceramic radiants for combustion to heat the radiants to a temperature for producing the infrared light waves. The positive pressure created within the oven by the gas/air mixture and combustion causes a continual discharge of the hot gases from the oven through a flue duct without a draft normally created by the introduction of secondary air.

Abstract: A method and system for handling, that is routing and tracking, a plurality of incoming media streams of varying types - such as faxes, e-mail, Voice over IP, and others - is disclosed. The system analyzes the incoming media's type, header information and content and, in conjunction with other databases available within an enterprise, such as a human resources or customer information management databases, determines a plurality of suitable enterprise resources that may be able to adequately respond to said incoming media stream. The system may, again in conjunction with the enterprise databases, determine the availability of an identified enterprise resource and, if available, routes said incoming media stream to said identified and available resource. If the identified resource is unavailable, alternate resources are selected from said plurality of identified resources for possible routing of the incoming media stream. The system also tracks the disposition of the media stream by the identified and available resource, and if said disposition of said media stream does not occur within a predetermined time, the system increases the priority of said media stream and re-routes the media stream within the enterprise. The system also maintains a database of statistics relating to the receipt and disposition of incoming media streams.

Abstract: The dressing chair is a bedside chair designed especially for elderly people to help them make a safe and easy transition from a prone position in their bed to (including dressing) that point in time at which they are ready to grasp any ambulatory device that they may use to continue with their daily activities.  Likewise, it helps them make a safe and easy transition from their ambulatory device to (including undressing) a prone position in their bed, ready for a good nights sleep. The dressing and undressing activities in the aforementioned transitions are made safe by providing a sturdy seat to sit on during certain dressing tasks, and by rails on three sides for grasping during movements, or for leaning against during other dressing tasks. Dressing and undressing are made easy by the combined seat and rail designs which make it easy to transfer from a sitting to a standing position and vice versa, without the need for any artificial lifting devices.
