Patent CA-2011615-A1 (CA)
Inventor: SODEN GEORGE
IPC: F24H3/04
Filed: 1990-03-07
Abstract: ABSTRACT       An electrically powered heater for instantly heating the interior of motor vehicles and the like uses DC current to actuate a plurality of heating coils located in an under-dash mounted casing.  The casing has an air flow passage therein and a motor driven fan arranged to draw ambient air through apertures in the rear of the casing, over the heated coils and back into the vehicle interior through the front of the casing.  Each heating coil is connected either singly or in pairs with a manually operated toggle switch so that each coil may be turned on separately or all coils together to adjust the heat and power consumption levels.  The fan is separately switched and may be operated independently of the coils.  An electronic control circuit for the heater includes an on-off switch and a manually adjustable time delay network which automatically turns off the heating coils after a preselected time.

Patent CA-2017770-A1 (CA)
Inventor: ERNST RICHARD J
IPC: B05C17/015
Filed: 1990-05-29
Abstract: A pneumatically actuatable dispenser for a two-part adhesive, as provided in a cartridge having two chambers and having a mixing nozzle mounted to a first end, each chamber having a plunger accessible from a second end. A front frame holds the cartridge.  A piston is arranged to be selectively driven within a cylinder in a forward or reverse direction.  A pair of piston rods operate in tandem to drive the plungers toward the nozzle, when driven conjointly with the piston in the forward direction. A first valve, when actuated, delivers pressurized air driving the piston in the forward direction. A second valve, when actuated, delivers pressurized air driving the piston oppositely. A third valve, when actuated while the first valve is actuated, vents pressurized air from the cylinder. A first control rod, which moves conjointly with the piston, and a second control rod may be selectively linked to each other for conjoint movement or unlinked from each other, via a linking lever and a cam. An actuator, which is positionable adjustably along the second control rod, actuates the third valve after conjoint movement of both control rods and the actuator, along with the piston, by a distance correlating to a controlled dose of the mixed parts of the adhesive. A valve can be manually actuated to divert pressurized air, via a hose, to a nozzle for blowing water or debris from a hole to receive the adhesive.

Patent CA-2023880-A1 (CA)
Title: Electronic control for an appliance
Inventor: BASHARK LARRY THOMAS
IPC: B30B15/26
Filed: 1990-08-23
Abstract: ABSTRACT An electronic control for a motor which eliminates the motor centrifugal switch and more particularly a control for a domestic refuse compactor which permits the user to control the approximate full trash bag weight and obtain more compaction from a split phase induction drive motor. A ferrite core sensor on the main winding of the drive motor samples the lagging phase angle of the motor main winding current during a compaction stroke. A low force cycle is achieved by terminating the stroke as soon as phase samples fall below a threshold defined at the start of each cycle by a locked motor main winding phase sample acquired prior to starting the motor. A medium force cycle terminates the stroke when compaction forces exceed the main winding breakdown torque. A high force cycle is achieved by re-activating a motor start winding when compaction forces exceed the main winding breakdown torque and terminating the stroke as soon as the phase samples exceed a threshold defined at the start of each cycle during motor starting. The control uses programmed referencing techniques to eliminate factory pre-calibration.

Patent CA-2030303-A1 (CA)
Title: Hollow fiber bundle element
Inventor: PAN CHUEN Y
IPC: B01J35/06
Filed: 1990-11-20
Abstract: A hollow fiber bundle element is provided comprising a bundle of microporous hollow fibers disposed in a cylindrical impermeable casing. with respect to each fiber, its wall is selected to provide a permeability in the microfiltration range (0.05 to 5 micrometers). The bundle forms two longitudinal passageways, being the lumina of the fibers and the other being the void space between the fibers. A first of these passageways is densely and uniformly packed with minute solid particles. No binder is used to fix the particles - they maintain their distribution in the passageway as a result of having been densely packed under pressure. The ends of the first passageway are sealed and the fiber wall pores are smaller than the particles, whereby the particles are immobilized therein. The hollow fiber module packed with minute adsorbent particles in the first passageway provides an adsorber. A fluid mixture comprising a carrier and an adsorbate is introduced into the second passageway. The adsorbate diffuses through the fiber walls and is collected by the adsorbent particles. By way of result, the particles used in this adsorber can be of much smaller size than those used in a conventional fixed bed column. The use of small adsorbent particles enhances adsorption rate, and availability of a separate longitudinal flow passageway reduces pressure drop across the adsorber. Alternatively, the hollow fiber module may be packed with minute catalyst particles to provide an effective catalytic reactor with improved mass transfer between the catalyst particles in the first passageway and surrounding fluid containing the reactants, in the second passageway.
