The outer panel is secured to the inner panel with the window frame disposed within the two panels. Hinge and latch elements may be connected to the metal frame through the inner panel.

Abstract: A bracket for supporting a cover structure for the contact rail of electric railroads which is made of plastic materials and in which the supporting bracket for the cover structure is so formed that it has a substantially uniform cross sectional thickness and forms a channel opening away from the rail which facilitates manufacture and reduces weight.

Abstract: An overhead wiring arrangement for a railway car includes an enclosed raceway attached to the main roof. The raceway includes a plurality of wires to be distributed to different locations in the car. Some of the wires are then diverted in different paths to different locations down into the interior of the car. Some of the wires pass through the raceway for connection to a flexible cable leading to a next adjacent car.

Abstract: A water ski formed of molded upper and lower shells made of sheet molding compound which have mating and overlapping flanges around the entire perimeter of the shells which are bonded together to form a buoyancy chamber. In one embodiment, the chamber is filled with polymerized foam and in another embodiment longitudinally extending ribs are formed to maintain the upper and lower surfaces of the shells in spaced relationship to each other.

Abstract: An environmental testing system for a product such as a railway car or a trailer includes a seismic mass having a "T" shaped cross-section, supported by a plurality of air mounts or cushioning means. The seismic mass is subjected to compression due to post tensioned reinforcement in three directions. A plurality of actuators are connected between the seismic mass and the product being tested to vibrate the product in accordance with a desired program. The reaction forces from the product under test are absorbed by the seismic mass and the air mounts. The air mounts are connected in series with a large air reservoir to permit the system to be tested under very low resonant frequency conditions.

Abstract: A door connected between reinforced "A" and "B" posts of an automobile includes a horizontal beam extending from the front to the rear of the door. Extension members are connected to the beam with interlock members connecting the extension members to the side sill of the automobile.

Abstract: A plastic door comprises inner and outer sub-assemblies. The inner sub-assembly includes the inner trim, panel, hardware mounting panel, window mechanism and other hardware which may be manufactured off line and attached to the outer sub-assembly as one of the final steps in the manufacture of the automobile on an assembly line.

Abstract: A pre-heater for fuel includes a corrugated tubing for passing hot water therethrough. An outer cylinder forms a jacket around said corrugated tubing to form a chamber to receive therethrough the fuel to be heated. The heat from the hot water is transmitted through the corrugated tubing to heat the fuel. Welding of the ends of corrugated tubing and the outer cylinder to end enclosures provide effective sealing among the parts.

Abstract: A construction beam includes solid strips of material forming inner and outer skins. Foam plastic material is disposed between the solid strips. Means are provided along the top and bottom of the strips to interlock one beam with a next adjacent beam to form a structure. Means for locking the strips to the foam plastic material may be provided.

Abstract: A forced steering mechanism is connected to a truck to steer an axle and associated wheels. Coupling means are provided for loosely connecting the car body of a vehicle to the truck and the forced steering mechanism. The coupling means permits relative lateral movement between the car body and truck while maintaining the forced steering mechanism in a position so as to permit self steering, but no forced steering when the vehicle is moving over tangent or rectilinear tracks. At the same time the degree of such lateral movement and amount of self steering is limited. The coupling means causes the forced steering mechanism to become operative when the vehicle is moving over sharply curved tracks.

Abstract: A tapered blade for use in a windmill comprises a main spar or beam assembly having top and bottom flat sheets of metal. Tapered angle strips are welded along the edges of the sheets. With the sheets and strips twisted to the proper angles, they are joined together by shear web channels welded along the edges of the strips. Leading and trailing edge assemblies, comprising primarily foam material, are bonded to the spar. A fitting is provided to permit the blade to be attached to the mechanism to be driven on the windmill.

Abstract: A molded plastic replacement handle for a tool, such as a sledge hammer, which includes an opening tapered from both ends so that the narrower part is located close to the center of the tool. A plastic adapter element is dimensioned to fit over one end of the handle and includes a tapered area in the same general direction as the bottom taper in the opening in the tool. After placement of the adapter element on the handle, the tool is placed on the adapter element. A metal insert having an opening therein is dimensioned to fit over to enter space between the top tapered area of the tool and the handle. The metal insert includes bottom sections disposed to bend inwardly into the space when the insert is forced downwardly to secure the tool to the top of the handle.

Abstract: A band comprising continuous glass fibers provides intrusion resistance for a plastic door mounted between two vertical posts in an automobile. The continuous fibers of the band are disposed horizontally and may be separate from the door or form an integral part thereof.

Abstract: A wheel anti-lock system includes switching means located outside of a vehicle wheel with means passing from the switching means through or across the wheel to a source of control pressure inboard of the wheel which controls the application of service pressure to the brake of the wheel.

Abstract: A power actuating mechanism uses a mechanical spring to normally urge a pin through openings in a track and rail of a trailer and bogie, respectively, to lock the trailer to the bogie. Structure is provided to selectively apply air pressure to an actuator to overcome the bias of the mechanical spring and move the pin out of the opening in the track of the trailer to unlock the bogie from the trailer for repositioning or removal.

Abstract: An anti-locking mechanism includes an assembly attached to move with a wheel of a vehicle. The assembly includes a spring biased inertia wheel movably mounted to a manifold. A valve connected to control the application of braking pressure is normally held closed when the inertia wheel and manifold are rotated at the same rate by the wheel. When the vehicle wheel is decelerated at an excessive rate, the inertia wheel overcomes the bias of the spring and continues to rotate about the manifold to open the valve and prevent braking pressure from being applied to the wheel.
