Patent CA-2351933-A1 (CA)
Inventor: LEE BRIAN THOMAS
IPC: F16N7/38
Filed: 2001-06-27
Abstract: A sump for use with a transmission or lubricating system of an internal combustion engine includes a sump pan which has a partition wall supported therein, the partition wall having an opening therethrough in which is positioned a filter element. The partition wall divides the pan into an upper chamber and a lower chamber with a suction tube that passes through the partition wall and projects, into the lower chamber. Dirty oil pools in the upper chamber and then passes through the filter element into the lower chamber by gravity and by suction created by a recirculation pump attached to the suction tube. In order to keep the partition from flexing so that the filter element restricts flow of oil in the lower chamber to the suction tube, a plurality of spacers are mounted between a frame of the filter element and the floor of the lower chamber. The spacers maintain a gap, which gap provides a channel allowing filtered oil to flow without undue restriction or blockage to the suction tube.

IPC: B66F7/24
Filed: 2002-04-17
Abstract: The vehicle leveller consists of one or more pieces of flexible material of sufficient length and width, which may or may not be tapered on either end. The base of the vehicle leveller (A  in Figures 1 and 2) are placed on the leveling surface and are thin enough to allow a vehicle or trailer to be driven on top. A second layer of flexible material (B in Figures 1 and 2) could be fastened to (A) by mechanical or other means (E). Additional layers of flexible material (C in Figures 1 and 2) may be fastened to (B) in a similar manner as (B) to (A). The balance of the material behind the fasteners (E) are left unfastened and can be lifted and separated from one another. This allows separate, shorter pieces of flexible material (D in Figures 1 and 2) to be inserted between (A) and (B) or (B) and (C) at the unfastened end, thereby adding to the overall height of the vehicle leveller. Additional pieces of (D) can be added and placed between (A) and (B) or (B) and (C) as required. Specifications

Title: Eye tracking and positioning system for a refractive laser system
Inventor: FREEMAN JAMES F
IPC: A61F9/007
Filed: 2000-08-10
Abstract: An eye tracking, and positioning system (10) for use with a refractive laser system (14) includes a camera interface (30), a computer (12), and a system for moving the patient relative to the laser beam. The computer (12) includes a video frame grabber (32) which extracts images of the eye from the camera (22), and is programmed to perform an eye tracking algorithm. The eye tracking algorithm calculates the exact center of the eye pupil, and compares the center with the desired location of the laser beam, as determined by a surgeon, with an image processing algorithm. If the relative location of the eye center, the laser beam fall outside a predetermined value, the patient chair (42), and thereby the patient, is repositioned relative to the laser beam, as opposed to the laser beam being repositioned relative to the patient.  The repositioning counters the movement of the eye.
