Title: Dual polarized array antenna with central polarization control
Inventor: RUNYON DONALD L
IPC: H01Q21/26
Filed: 1996-12-11
Abstract: A planar array antenna (12) having radiating elements characterized by dual simultaneous polarization states and having substantially rotationally symmetric radiation patterns. A distribution network (16), which is connected to each dual polarized radiator, communicates the electromagnetic signals from and to each radiating element. A ground plane (14) is positioned generally parallel to and spaced apart from the radiating elements by a predetermined distance. The conductive surface of the ground plane operates to image the radiating elements over a wide coverage area, thereby enabling a radiation pattern within an azimuth plane of the antenna to be independent of any quantity of radiating elements.  A central polarization control (18) network (PCN), which is connected to the distribution network (16), can control the polarization states of the received signals distributed via the distribution network by the radiating elements.

Title: Rv refrigerator with combustion seal and heat deflection
Inventor: LEISTNER DAVID W
IPC: B60H1/32
Filed: 1998-06-26
Abstract: A refrigerator for recreational vehicles comprising a generally cubic cabinet having front, back and top sides along with absorbent-type refrigerating apparatus on the back side. A flap member adjustably mounted on the back side at a position above the refrigerating apparatus extends upwardly and outwardly from the cabinet into sealing engagement with the walls of the compartment in the recreational vehicle in which the refrigerator is installed. The configuration of the flap member and the mounting of the flap member so that it can readily be adjusted to a number of positions enhances the ability of the flap member to prevent gases created by the refrigerating apparatus from propagating into the living quarters of the recreational vehicle.

Patent CA-2250774-A1 (CA)
Title: Novel elastomer composites, method and apparatus
Inventor: RUMPF FREDERICK H
IPC: C08C1/14
Filed: 1997-03-25
Abstract: Elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end. Highly efficient and effective elastomer coagulation is achieved without the need for a coagulation step involving exposure to acid or salt solution or the like.  Novel elastomer composites are produced. Such novel elastomer composites may be cured or uncured, and combine material properties, such as choice of filler, elastomer, level of filler loading, and macro-dispersion, not previously achieved.

Title: Process and devices for characterising ground water measurement points by distinguishing ground water from subterranean water accumulation
Inventor: NESTLER WOLFGANG
IPC: E21B47/10
Filed: 1997-05-14
Abstract: A process and devices are disclosed for characterising ground water measurement points by distinguishing ground water from subterranean water accumulation, and are useful in particular for determining the optimum pumping times of ground water measurement points for representative quality tests and for recognising and localising defects in ground water measurement points. The invention is based on the measurement of radon activity concentration or the total activity concentration of ground water samples. Measuring concentrations off-line or on-line makes it possible to reliably determine the ratio from ground water to subterranean water accumulation in a ground water measurement point. A new type of flow measurement cell and a bore hole probe are disclosed. The invention is applicable wherever quality tests of ground water are carried out.

Patent CA-2255174-A1 (CA)
Inventor: HAMLIN JAMES K
IPC: H04L29/06
Filed: 1998-12-03
Abstract: The present invention provides a system and method for communicating data between a source application process and one or more destination application processes.  This system and method perform conversion and routing functions which require only a single conversion of all outbound transmissions regardless of the variety of destinations, and only a single conversion of all inbound transmissions regardless of the variety of sources.  The functions also enable changes, additions, and deletions of sources and destinations of transmissions to be made without modification of a source or destination application process and without taking a source or destination application process off-line.  The functions further enable this system and method to be implemented in virtually any enterprise architecture without requiring that each processing system of the architecture be custom built.  These conversion and routing functions are performed by first receiving data to be transmitted in a source format from a source application.  This data are then converted from the source format to a standard format.  Next, one or more destinations are identified in a database using a transaction type corresponding to the data and/or the address of the source application. After identifying the one or more destinations, a copy of the data is transmitted to each and the data are then converted from the standard format to a destination format. Lastly, this converted data are passed to the destination process.

Patent CA-2260875-A1 (CA)
Inventor: STURMAN ODED E
IPC: F02M59/10
Filed: 1997-07-23
Abstract: A pump which has a digitally controlled internal by-pass valve (46). The pump includes a housing which has a pumping chamber (20) that contains a piston (18) which pumps fluid from an inlet port (14) to an outlet port (16) to the housing. The pump also has an intake valve (34) that moves to an open position when the pump draws in fluid and moves to a closed position when the piston pumps the fluid through the outlet port. The intake valve can be maintained in the open position by a separate hydraulic system so that the piston pumps fluid back through the inlet port and by-passes the outlet port. The separate hydraulic system includes a three-way solenoid control valve (46) which directs fluid to the intake valve to open the valve. The control valve may contain a pair of solenoids (56, 58) which latch an internal spool (60) to control the flow of fluid to the intake valve. The spool can be latched into position by a digital pulse that is provided by an electrical controller. The controller can control the output pressure of the pump by opening the intake valve and by-passing the outlet port.

Patent CA-2275407-A1 (CA)
Inventor: CHAPMAN ALAN STANLEY JOHN
IPC: H04L12/56
Filed: 1997-12-03
Abstract: Multi-media networks will require that a data flow be given certain quality-of-service (QOS) for a network connection but pre-negotiation of this sort is foreign to the current data networking model. The real time traffic flow in the data network requires distinct limits on the tolerance to delay, and the variations in that delay. Interactive voice and video demand that the total delay does not exceed the threshold beyond which human interaction is unacceptably impaired. The present invention allows the network to discover the nature of the service for each traffic flow, classifies it dynamically, and exercises traffic conditioning by means of such techniques as admission control and scheduling when delivering the traffic downstream to support the service appropriately.

Patent CA-2279090-A1 (CA)
Title: Portable door lock and alarm
Inventor: COX KELLY
IPC: E05C19/18
Filed: 1999-07-29
Abstract: A portable door lock and alarm is adapted to connected to the hinge carried between a door and a doorjamb. The portable door lock and alarm provides an enclosure housing a lock mechanism which includes a claw defining small and large hinge passages adapted to surround small or large door hinges. A bolt, extending from the claw and through the enclosure, is threaded onto a knob. After attachment of the claw to the hinge, rotation of the knob retracts the claw into the enclosure, increasing the pressure between the door and doorjamb and the enclosure. An attempt to open the door will increase the pressure on the enclosure; however, in a typical application, the door will crack, break or deform before the enclosure of the lock is crumpled. A circuit provides a switch that is closed if an attempt is made to open the door, thereby resulting in activation of an annunciator.
