Abstract: A weight handling vehicle having a rear cargo compartment with a bed and side walls. A frame adjacent the sidewalls supports a carriage that moves horizontally along the top of the frame and telescopes out the rearward end of the vehicle. A trolley, supporting a hoist for lifting the weight units, moves on the carriage and, when used in tandem with the telescoping carriage, transfers weight units from within the rear cargo compartment to a point exterior of and spaced apart from the rearward end of the cargo compartment.

Abstract: A structural element having two opposed and parallel U-shaped members opening toward one another with a web of elongated corrugated form extending between the first and second U-shaped members. The web has a first set of coplanar flats fixed to opposed coplanar first sides of the two U-shaped members and a second set of coplanar flats fixed to opposed coplanar second sides of the two U-shaped members. The first coplanar flats alternate with and are joined to the second coplanar flats by secondary flats which have stepped relief cutouts and are spaced apart from the U-shaped members.

Abstract: A method and apparatus for impregnating a fibrous web is disclosed having a conveyor for advancing the fibrous web. The fibrous web having a first surface and a second surface. An applicator is provided for applying a foamed binder to the first surface of the fibrous web and the foamed binder seals the first surface of the web. A vacuum chamber is positioned adjacent the second surface of the web. The vacuum chamber contains a narrow slot adjacent the second surface of the web for applying a vacuum to the web. The vacuum acts upon the web to reduce the thickness of the web and to draw the foamed binder material into the web to impregnate the web.

Abstract: An improved roof structure using flexible sheets of waterproof roofing material such as a felt backed polyvinyl chloride. An inverted generally V-shaped channel joins adjacent edges of the sheets of material. The channels have sides and an apex extending above the normal maximum water level on the roof structure during heavy rains. The adjacent edges of the material are bonded to the opposite sides of the channel and are further sealed by overlapping and bonding together or by a bonding to the inside of a second, overlapping inverted V-shaped channel. The air space in the first generally V-shaped channel may be vented to the atmosphere to prevent sweating beneath the roofing material.

Abstract: A brake or clutch pedal actuated safety switch for use with an automotive speed control system is disclosed. The switch opens an electric circuit and admits atmospheric air to a vacuum line when the brake pedal or clutch pedal is depressed. The electric circuit normally opens first to deactivate the speed control system electrically at the system's regulator, and the vacuum line is opened subsequently to act as a backup for deactivation of the system. A rotatably mounted lever member, biased by a spring toward the deactivating position, controls both the electric and the vacuum circuits. When the pedal is fully released and returned to its undepressed position, a tension line rotates the lever member against the bias of the spring to a position wherein the electric circuit and the vacuum line are closed.

Abstract: A store display fixture for hanging garments and the like is disclosed hag at least one hangrod affixed to at least one downwardly extending rectangular or round or square tube in telescopic engagement with another rectangular tube. The inner tube includes a compression spring-biased plunger projecting therefrom and through one of a column of openings vertically spaced apart along the outer tube. The end of the plunger is beveled to form both an upward and a downward inclined surface such that the tubes are locked into place against collapse during use but may be extended by merely pulling the downwardly extending tube upward. The tubes are retractable by manually depressing the plunger and allowing the downwardly extending tube to slide into a lower position.
