Abstract: A powered window regulator for use with a horizontally sliding window assembly may be disconnected from a sliding pane to permit manual operation of the window. The regulator has a tubular guide rail mounted adjacent and parallel to the lower edge of the window assembly by pivot brackets which engage the respective ends of the guide rail such that the guide rail is rotatable about the pivot brackets. A carrier block slides within the guide rail, and a portion of the block extends out through a longitudinal slot extending along the length of the guide rail to engage a pane attachment affixed to the sliding pane. The carrier block is moved reciprocally along the guide rail by a motor-driven cable to slide the sliding pane between open and closed positions. Rotation of the guide rail about the pivot brackets through approximately ninety degrees moves the carrier block between an upright position wherein it engages the pane attachment and a depressed position wherein it is disengaged from the pane attachment.

Abstract: A mechanically interlocking belt weatherstrip for a motor vehicle. The weatherstrip is formed by three separate components: a cover, a body and a sealing lip. The weatherstrip may be made from separate, all-extruded components, or may be a made from a combination of molded and extruded components. The weatherstrip is formed by snapping the body and the cover snap together to hold the sealing lip securely in place. Because the cover can be easily interchanged with a different cover, the cover can be made to include properties, such as color and gloss, desired by a particular motor vehicle manufacturer while the remaining components remain unchanged. Thus, the weatherstrip allows versatility of the selection of the separate components to meet the individual style and functional needs of a particular motor vehicle design.

Abstract: A system for servicing an overhead door having a spring counter balance mechanism, an operator and a directional control system. The servicing system includes a counter, information cards, and contact cards. The counter includes a counting device and a numeric display. The counting device records the number of full cycles of the springs used in the counter balance mechanism measured from the fully closed position of the door. The numeric display shows this number of full cycles. An inspector of the door compares this number to the cycle failure specification for the springs used in the counter balance mechanism listed on the information cards. If replacement or attention is required, the inspector uses the contact cards to inform the appropriate parties that the door is not functioning properly or that the springs require attention.

Abstract: A louvre shutter adapted to be assembled from elements forming a kit.
