Title: Apparatus for preventing whiplash
Inventor: DELLANNO RONALD P
IPC: B60N2/48
Filed: 1996-06-25
Abstract: A vehicle-installed supporting seat for a passenger (28) is provided, which includes a seat back (12) provided with an integral head-neck restraint (14) comprisi ng a cranium support portion (16) and a cervical spine support portion (18). Each portion  includes a layer of resilient material (20) supported on an underlying inflexible suppo rt shell (22), which together act to effectively define a contour (24) that interfits with the posterior contour (26) of the passenger's cranium and cervical spine. A controllably deformable energy absorbing crush zone (40) is disposed to the rear of the shell as to be compressed by the rearward displacement of the shell. The cervical and cranium support portions act to substantially simultaneously decelerate the cranium and cervical spine of  the passenger during a vehicle rear end impact while the controlled deformation of the cru sh zone absorbs energy, to prevent whiplash-related injuries to the passenger.</SDOA B>

Patent CA-2242188-A1 (CA)
Inventor: SUBLISKEY EDWARD J
IPC: E05C1/06
Filed: 1998-07-03
Abstract: The sash lock has a rotatable cam which engages the keeper. The sash lock has a slide plate mounted below the cam and the slide plate moves between a retracted position in which its leading edge is flush with the sash to which the lock is mounted. In an extended position in which the leading edge of the plate extends far enough to block the narrow gap between the sashes. The slide plate is mounted for movement perpendicular to the edge of the sash and parallel to the plane of the top surface of the sash. The slide plate includes an arcuate recess in one side of the plate which is engaged by a pin extending from the rotatable cam. The recess in the slide plate is contoured so that during initial portion of the movement of the cam from its open position toward its locked position, the slide plate does not move. After the cam has moved far enough to engage the keeper, the slide plate moves outward toward the sash to which the keeper is mounted so as to block the gap between the two sashes in the region of the cam. It reduces the chances of a sash lock being forced open.

Title: Crystal recognition by diffraction behaviour
Inventor: DICKSON DAVID BRUCE
IPC: G01N23/201
Filed: 1998-08-11
Abstract: The invention concerns a method of identifying a randomly oriented crystal (12). The crystal is irradiated with an X-ray or neutron beam and a Laue spot diffraction pattern is obtained. A transform, typically a radial arctangent transform, is then performed on the Laue spot diffraction pattern in order to produce a transformed image in which distortions in the Laue spot diffraction pattern are reduced. A determination is then made as to whether the transformed image is characteristic of a particular crystal.

Title: Drain filtering device
Inventor: SILVA CHARLES
IPC: B01D35/02
Filed: 1996-05-21
Abstract: A drain filtering device (44) is disclosed. The improvement over the prior art is comprised of reducing the filter size from an elongated device that spans the length of the gutter system (46) to a modular unit which is neccessary only at the drain site.

Abstract: A burner controller ( 10) for safe operation of a furnace has a an electromechanical latch (34) for holding first and second fuel valves (41, 42) open responsive to an enable signal. The latch comprises an armature (32) attached to the second valve (42) and an electromagnet assembly (33) attached to the first valve (41). When the electromagnet assembly (33) receives the enable signal and the armature (32) is attracted to the electromagnet assembly (33), the magnetic force opposes force of a spring (27) urging the first and second valve (41, 42) simultaneously closed. When the enable signal is not present, the spring forces (27) both valves (41, 42) into their closed position. An auxiliary valve (58) in series flow arrangement with the second valve (42) opposes flow of fuel passing through the second valve (42) in certain situations.
