Patent CA-2130108-A1 (CA)
Inventor: KOSAK KENNETH M
IPC: C12Q1/68
Filed: 1993-02-12
Abstract: Heat-releasable reagent compositions are disclosed comprising a dispensable body formed from a coating material (D) which entraps a reagent material (B).  The entrapped reagent material does not react until the dispensable body is heated to a min-imal temperature.  When heated to the predetermined temperature, the reagent is released into the surrounding medium and be-comes available for reaction with other substances in the medium. The heat-releasable reagent compositions are particularly use-ful in various types of nucleic acid hybridizations, polymerase chain reactions (PCR), reverse transcriptase reactions (RTR), nucleic acid sequencing and product generating reactions such as colorimetric, fluorometric and chemiluminescent enzyme lab-eled immunoassays.

Title: Exhaust system
Inventor: RAHN DANIEL
IPC: F24F7/003
Filed: 1995-03-20
Abstract: An exhaust system for residential applications which utilizes a remote central vacuum system and connected inline piping to remove stale air, odours, gases and steam from a room or enclosed area.  The polluted air is draw through an opening in the bottom of an outer housing to which the piping is connected by means of an opening at the top of the housing.  The polluted air is drawn over a solid faced baffle composed of a rigid material which is attached to the inner surface of the housing.  The central vacuum system then expels the polluted air to the outdoors.  The central vacuum system is turned on by means of a manual switch in the room.  The vacuum is supplied to the top of the housing by means of a valve set in the piping which can block the flow through the piping.      This valve can be operated from within the room as well.   The manual switch and the valve are preferably operated at the same time by means of a dual purpose switch.

Title: Process for preparing ammonium zeolites of low alkali metal content
Inventor: COOPER DAVID A
IPC: B01J37/30
Filed: 1994-07-20
Abstract: Ammonium zeolites of extremely low alkali metal content are prepared by a process of potassium ion exchange followed by ammonium ion exchange. Zeolite X or zeolite Y that contain a significant amount of sodium are contacted with a potassium salt solution under conditions that provide a substantial exchange of potassium for sodium. The potassium enriched zeolite is then contacted with an ammonium salt solution so that the ammonium ion replaces the sodium and potassium ions. The resulting ammonium zeolite X or Y contains considerably less than 1 % alkali metal calculated as Na2O.

Title: Coil tubing injector unit
Inventor: ELLISTON TOM
IPC: E21B19/22
Filed: 1995-06-23
Abstract: A coil tubing injector unit is shown for injecting tubing into a well bore. A main injector frame is positioned adjacent the well bore and includes a longitudinal opening which defines a vertical run for the injector unit which is alignable with the well bore vertical axis. Gripper block assemblies are carried on the main injector frame and include plier-like halves which are pivotable between an open position and a closed, gripping position as the assemblies enter the vertical run so that the plier halves grip a selected length of tubing fed into the main injector frame along the central vertical axis of the injector unit to inject the tubing into the well bore. The profile of the vertical run is designed to minimize loading on the gripper block assemblies. The section modulus of the material used to manufacture the vertical run is also designed to allow a controlled flex of the run in order to soften the gripper loading as the gripper block assemblies enter the vertical run.

Title: Prism Light Guide Luminaire with Efficient Directional Output
Inventor: WHITEHEAD LORNE A
IPC: G02B6/42
Filed: 1994-02-22
Abstract: A prism light guide luminaire (84)  has opaque (102)  and  light  emitting  (88)  surface  portions  which together form a selected cross-sectional configuration. The opaque surface portion has a light reflecting characteristic. The light emitting surface portion is prism light guide material  (100)  which confines,  within the luminaire, light rays which strike the material at angles falling within the material's acceptance angular range. Within the luminaire,  a light scattering area  (92,  94) having a predefined shape and location redirects light into angles falling outside the material's acceptance angular range.  The luminaire's cross-sectional configuration, the opaque surface portion's light reflecting characteristic, and the shape and location of the light scattering area are selected  such that  (i)  light redirected  by the  light scattering area which does not pass directly from the scattering area to the light emitting surface portion and escape through that portion is substantially efficiently reflected by the prismatic material directly back onto the scattering area; and, (ii) all paths along which light may pass directly from the scattering area to the light emitting surface portion define a solid angle less than 2.pi..
Patent CA-2160813-A1 (CA)
Inventor: CORBETT STEVEN R
Filed: 1995-10-18
Abstract: The invention provides a method of transporting freight by truck between two load points located long distances apart.  The method comprises dividing the route between the load points into segments, each segment being a distance of about a half days' drive for a driver and each segment between the load points terminating in switch points.  Trucks carrying freight are dispatched from each load point towards the other at about the same time.  A driver of each truck meets a driver and truck with a load of freight dispatched from the opposite direction at about the same time so as to meet at the adjacent switch point. The drivers are switched at each switch point so that each driver will then return to the point from which that driver commenced.  The progress of the trucks towards the switch points is monitored and the location of the switch points are adjusted, if necessary, so the trucks will arrive at the switch points at about the same time, whereby the freight from each load point will continue on non-stop in a similar manner to progressive switch points and to its final destination while each driver will return to that driver's starting point each day with another load of freight.
