Publication number: 20020140251Abstract: A window assembly for a vehicle provides at least one fixed panel or window and a movable panel or window. A one piece frame is formed which includes a perimeter frame and at least one dividing member. The window panel assembly may be adapted for a vehicle door, whereby the fixed window panel is secured to the dividing member and a portion of the perimeter frame, while the movable window panel slidably engages a portion of the perimeter frame with one edge and the dividing member with the other edge, which is opposite the first edge. A rail or guide member is secured to the second edge of the movable panel for slidable engagement with the dividing member. The rail member and guide member allow the movable window panel and fixed window panel to form a substantially flush, continuous, planar surface across their adjacent edges, while still providing a substantially airtight seal therebetween.Type: ApplicationFiled: May 24, 2002Publication date: October 3, 2002Applicant: Donnelly Corporation, a corporation of the State of MichiganInventors: Timothy A.

Patent number: 6394529Abstract: A window assembly module for a vehicle comprises at least one fixed window panel having an inner surface and an outer surface, a movable window panel having an inner surface and an outer surface, and a frame configured to secure to the vehicle. The inner surface of the at least one fixed window panel is secured to the frame. The movable window panel is movable relative to the frame. The frame includes a portion separating the at least one fixed window panel and the movable window panel. The portion of the frame is adapted to maintain the outer surface of the movable window panel generally flush with the outer surface of the fixed window panel as the movable window panel is moved relative to the frame. The window assembly is suitable for use as either a side door window of a vehicle or a rear window of a vehicle.Type: GrantFiled: August 24, 2001Date of Patent: May 28, 2002Assignee: Donnelly CorporationInventors: Timothy A.

Patent number: 5072145Abstract: A generator housing including a housing module having at least one relatively complex internal passage formed therein and housing flow control components for circulating a fluid coolant through the generator. The housing module is formed by forming a plurality of sub-components each having at least one relatively simple passage formed therein for defining part of the at least one relatively complex internal passage. The sub-components are combined together as by bonding to form the housing module with at least one relatively complex internal passage. The flow control components are contained in bores within the housing module in fluid communication with the relatively complex internal passage therein. The housing module if formed of a relatively lightweight, non-metallic material to enable reduction in the weight of the generator housing in cost-effective and technically accepted manner thereby providing an improved generator which can be used in aircraft.Type: GrantFiled: September 5, 1990Date of Patent: December 10, 1991Assignee: Sundstrand CorporationInventors: Timothy A.
