Appl. No.:

10/112337

Inventors:

Joseph Lucas - Portland OR, US
Thomas English - Portland OR, US

International Classification:

E06B003/00

US Classification:

Abstract:

A seal for a fixed window in a motor vehicle, including a pane-holding channel to receive and grip the opposite faces of a margin of a window pane. A sealing lip extending parallel with the pane-holding channel has a root located a small distance apart from the top edge of the pane-holding channel, and an outer margin of the lip extends to and presses sealingly against an outer surface of the window pane. In a preferred embodiment of the invention an outer margin of the main member of the seal defines a channel to receive and grip the opposite faces of a margin of the structure defining a window opening in the motor vehicle. A locking strip engaged in a locking strip groove keeps the seal in place after installation. Where two seal members meet, the respective sealing lips meet to form a curved concave corner.

Abstract:

A structural arrangement for an embedded and sealed railroad track and a method for its installation to provide a gutter defined along the rails of such a railroad track extending along or across a street or highway with rail tops at pavement level. Rubber filler bodies are held in place along the sides of each rail by retainer strips which lock into place on the filler bodies. A retainer form holds the filler bodies in place and provides space for the retainer strips when pavement materials are cast in place along the rails. Protective caps and sealing structures are installed before pavement materials are cast in place, to exclude the paving materials from space needed as a gutter along the rails to provide access to the rails and to spaced-apart supporting structures to which the rails are fastened, and to keep foreign materials from getting on the top of the rails and prevent them from becoming caught between the rails and the adjacent filler bodies.

Abstract:

A liquid-flow control valve with pressure-sensitive gas-bleed apparatus having a debris-catching feature. Included is a disc sealingly seatable selectively against a valve seat to open and close the valve. Apertures, which extend through the disc, remain open when the disc is seated on the seat. An aperture closure device, disposed adjacent the disc on the side from which fluid normally flows, has a pressure-responsive flex web biased by natural internal relaxed-state memory to form, in cooperation with the disc, a cavity which communicates with the apertures. The web has openings which are offset from the apertures when viewed along the adjustment axis of the valve and which communicate with the cavity. The web is moveable under the influence of liquid pressure from within the body toward the disc to collapse the cavity and to close the apertures when the disc is seated on the seat.
