Patent CA-2366278-A1 (CA)
Title: Vent closure member with lift spacer
Inventor: SELLS GARY L
IPC: F24F7/02
Filed: 2001-12-27
Abstract: A ridge vent assembly extends along a roof ridge of a building. One embodiment has corrugated plies defining small diameter passages that communicate a vent opening cut along the ridge of the roof with ambient atmosphere. A moveable valve member extends along the outer edge of the vent parts and includes a lift spacer to keep the valve member spaced from the roof when in an inactive position. When wind speed increases above a predetermined wind speed, the movable member moves into a position adjoining the edge of the vent parts and the bubble is compressed against the upper edge of the corresponding vent part, thereby preventing entry of wind driven moisture and snow into the passages and into the building structure through the vent opening. Accordingly, the moveable valve member acts as a weatherstripping material for the vent. A similar flexible member is usable to weatherstrip windows, doors, and other building openings.

Patent CA-2376344-A1 (CA)
Inventor: ZHU PETER
IPC: G01N21/77
Filed: 2002-03-12
Abstract: A simple assay is described to determine the presence of a point of interest of an aldehyde such as OPA, glutaraldehyde or formaldehyde in a test solution such as a disinfectant. The aldehyde is reacted with a calculated amount of a reagent such as sodium bisulfite or sodium cyanide. This reaction produces a solution with a first color. This first color may be colorless. The remaining aldehyde is reacted with a compound containing an amino group such as an amino acid to produce a second color. The observation of a color confirms the presence of a certain amount of the aldehyde in the test solution. If no color is developed, then the aldehyde concentration is below a certain specification. The specific concentration point may be adjusted to practically any point by adjusting the amounts of the chemical reagents used or by using a different amount of aldehyde in the solution to be tested.

Title: Image projection system and its method of use
Inventor: MARTIN TRENT
IPC: G03B21/10
Filed: 2002-04-18
Abstract: The present invention provides a projection system for the display of images in a wide range of ambient light conditions. The system comprises a system control component, two or more projectors and a screen unit. The system control component synchronises two or more images for projection by the projectors, with the image synchronisation enabling the generation of a coherent single image from multiple projected images. There are two or more projectors which project separate images and each projector projects an image onto a unique area of a screen unit. The synchronisation of the projectors is also controlled by the system control component. The screen unit has one or more screens for receiving the projected images and these screens are compatible with a rear projection system. The screens incorporate a contrast enhancing component which improves the resistance of the projected image to contrast degradation due to a wide range of ambient light conditions.
