Patent CA-2124472-A1 (CA)
Title: Utility vehicle bed partition
Inventor: GOSNELL RAYMOND H
IPC: B60P7/14
Filed: 1994-05-27
Abstract: Abstract A bed partition arrangement for a utility vehicle such as a pickup truck in which a flat panel has laterally opposed side edges and a bottom edge.  A pair of latches are disposed at the respective side edges of the panel, with each latch including a latch bar for engagement with opposed longitudinally spaced openings in a pair of rails mounted along opposed sidewalls of the vehicle bed.  The latch bars are urged by coil springs laterally outwardly of the panel for releasable locking engagement with openings in the side rails, and the latch bars are movable by handles inwardly against the springs for selective positioning of the panel lengthwise of the vehicle bed.  Resilient feet are carried along the bottom edge of the panel for compressive frictional engagement with the floor of the vehicle bed when the panel is mounted between the side rails to hold the panel in position and prevent the panel from swinging about the axis of the latches.

Inventor: DOBROWOLSKI JERZY ADAM
IPC: H01J29/89
Filed: 1994-06-01
Abstract: An optical filter is provided for suppressing unwanted reflections of background light when used with a display device such as a cathode ray tube or an electroluminescent screen, or in optical communication or surveillance. The filter has multiple thin layers including a first series of layers for suppressing reflections from its outer surface and a second series of layers constituting a bandpass interference filter. The first series of layers is arranged to suppress reflections over a broad wavelength band while the second series of layers allows transmittance over a relatively narrow wavelength passband within the broad wavelength band, resulting in improved contrast when the display is used in situations of high background light.

Patent CA-2137318-A1 (CA)
Title: Electric accumulator
Inventor: LICHTENBERG FRANK
IPC: H01M10/34
Filed: 1994-12-05
Abstract: The positive electrode of a Ni/metal hydride accumulator is formed from a mass mixture of Ni(OH) 2 and an oxidation-resistant graphite.  The stable graphite is notable for a high degree of crystallinity and a low ash content.  In conventional Ni/metal hydride accumulators, cobalt compounds play an essential part in developing a conductive matrix within their positive nickel hydroxide electrodes, leading to reductive destruction of the matrix by severe high temperature short circuit testing.  In contrast, the same accumulators, with positive electrodes produced according to the present invention, survive the test with only a temporary and slight decline in capacity.

Patent CA-2138966-A1 (CA)
Title: Ceiling vent with movable vane
Inventor: PETTERSON BART
IPC: F24F11/75
Filed: 1993-06-21
Abstract: A ceiling vent (10) diffuses air from a heating or cooling system in a laminar flow into a room for optimum dispersion in the room. Inlet air strikes a hinged vane (26) within the vent. The vane deflects the air in a narrowing air way along a continuous concave curvature and extending all the way to the outlet opening of the vent.  The vane responds to the force of air flow to narrow or enlarge the air way and, thus, regulate the velocity of air exiting the vent. A curved air catch (32) associated with the vane directs the outflow of air and also laterally disperses air within the vent.  The vent maintains a relatively constant velocity and diffusion of air into a room despite variable flow rates from the source of air.

Patent CA-2158412-A1 (CA)
Title: Apparatus for de-entraining liquid in gas scrubbers and the like
Inventor: TAUB DAVID B
IPC: B01D45/16
Filed: 1995-09-15
Abstract: A mass contactor apparatus is provided which includes an annular-shaped enclosure having an inlet for introducing gas thereinto. An entrainer deflects air flowing into the inlet into a hollow interior region of the entrainer, thereby creating a vortical flow of gas within that hollow interior region. An annular outlet enables the vortical gas flow to move upwardly and out of a central region of the entrainer. A de-entrainer is positioned directly upon the entrainer for deflecting vortical flow, entering into an inlet of the central region surrounding the outlet, radially-outwardly through spaces provided between vertically-aligned, curved deflection plates in the de-entrainer to create an upward, outward circular flow along an interior surface of the enclosure. A  liquid source delivers liquid to the hollow interior region of the entrainer so that the vortical gas flow draws the liquid into intimate contact therewith. This causes the liquid to be accelerated and broken up into a cloud of droplets which approach a velocity of, and move in a direction of, the vortical gas flow. A cone is positioned directly upon a top of, and covers, the de-entrainer, thereby causing droplets to move downwardly along the cone, and thereby preventing the droplets from being re-entrained with upwardly flowing scrubbed gas in a central region of the enclosure.
