Abstract: An independent adjustable axle suspension system for mounting a wheel to a frame of a trailer for transport of the trailer over a support surface. The axle suspension system includes a tower adapted to be attached to the frame and an axle unit adapted to receive the wheel. The tower is selectively moveable with respect to the axle unit along guide assemblies between extended and retracted positions to thereby selectively position the height of the frame with respect to the support surface.

Abstract: A frame for securing a wind deflector to a trailer includes a pair of vertically extending pivot tubes and brackets. The tubes include swing C washers which hook about a rod on each bracket. A pair of vertically extending support tubes is spaced apart by a pair of horizontal crossbars. The vertical pivot and support tubes are joined by upper and lower horizontal pivot tubes. The lower horizontal pivot tubes are spaced apart by an adjustable horizontal crossbar. Legs equipped with brackets extend from both ends of each vertical support tube. The wind deflector is secured to the frame by fasteners inserted in the brackets on the legs. In its lower position, the deflector is flush against the side of the trailer. The deflector may be raised to an intermediate position by pulling it away from the trailer, thereby swinging the horizontal pivot tubes outwardly with the vertical support tubes.

Abstract: A door hold back for holding the cargo door of a vehicle in the open positon while the vehicle is being loaded and unloaded wherein a link having spherical end portions is connectable between a socket provided in a mounting plate on the vehicle wall and a socket provided in a receiver on the cargo door. The spherical end portion on one end of the link in the base plate socket is larger than the spherical end portion on the other end of the link in the receiver socket so that the larger spherical end portion of the link is captivated in the base plate socket, and the smaller spherical end portion is releasably mounted in the receiver socket. The link and associated spherical end portions, mounting plate and receiver are all molded of high impact polypropylene plastic.

Abstract: A method and apparatus is provided for dispensing beer from a keg without excess foaming wherein the keg and beer temperatures and fluid pressures are controlled such that beer is dispensed at predetermined temperatures at substantially atmospheric pressures even over a wide range of atmospheric temperatures. Beer is supplied under pressure from the keg to a constricted flow line which abruptly decreases flow pressure. A portion of the constricted flow line is immersed in a refrigerating bath to reduce beer temperature. The length of the constricted flow line to the dispensing nozzle is sufficient long and its internal diameter sufficiently smooth that beer flow therethrough is stabilized to significantly reduce turbulence. Beer pressure drop through the nozzle is minimal and beer flow is relatively laminar.The portion of the constricted line immersed in the refrigerating bath is formed from coiled tubing. The bath fluid is recirculated and the bath temperature is sufficiently low as to cause ice to form.
