Abstract: A vehicle bumper and underride crash guard protection device to prevent other vehicles underriding the protected vehicle. The bumper or guard system uses pre-tensioned brake plates which absorb energy by moving at a predeterimined force. The bumper structure has a pivoting arrangement such that upon contact of the main bumper guard by a vehicle, the pivoting member transmits the horizontal force of the moving vehicle to the pre-tensioned energy absorption devices usually located under the vehicle. The bumper system allows large, load-carrying vehicles to comply with certain vehicle regulatory requirements for a crash guard bumper with the capability of deforming, moving or absorbing crash forces at predetermined impact points in a predetermined and regulated fashion.

Abstract: Two wheeled units of a vehicle are adjustably interconnectably positioned relative to each other. An apertured track assembly is stationarily mounted on one of the units, while a locking assembly is mounted on the other of the units. The locking assembly includes at least one locking pin displaceable into and out of at least one aperture on the track assembly. The locking assembly may be unlocked either manually or with power assistance. The two wheeled units may be leading and trailing cargo units of a vehicle whose spacing apart from each other is to be controlled in a load-bearing drawbar arrangement. Alternatively, the wheeled units may be a bogie subframe mounted underneath a cargo unit and movable relative thereto for better weight distribution of the payload in a suspension system.

Abstract: In a cargo-carrying vehicle having a power unit, a first cargo-carrying unit releasably affixed to the power unit, the first cargo-carrying unit not being pivotal on the power unit, and a second cargo-carrying unit releasably and pivotally connected to the first cargo-carrying unit, wherein the improvement comprises:a drawbar affixed to said cargo-carrying unit;an eye affixed to a free end of said drawbar;a safety hook connected to said drawbar;a chassis affixed to said first cargo-carrying unit;a ring affixed to said chassis and adapted to receive said safety hook; anda coupler affixed to said chassis and adapted to engage said eye.

Abstract: In a cargo-carrying vehicle having a power unit, a first cargo-carrying unit releasably affixed to the power unit, the first cargo-carrying unit not being pivotal on the power unit, and a second cargo-carrying unit releasably and pivotally connected to the first cargo-carrying unit, wherein the improvement comprises:a plurality of cross members extending across the width of the second cargo-carrying unit;a tie plate located on each lateral edge portion of the second cargo-carrying unit, said cross members being rigidly affixed between said tie plates; anda drawbar rigidly affixed to said cross members.

Abstract: In a cargo-carrying vehicle having a power unit, a first cargo-carrying unit releasably affixed to the power unit, the first cargo-carrying unit not being pivotal on the power unit, and a second cargo-carrying unit releasably pivotally connected to the first cargo-carrying unit, wherein the improvement comprises:said power unit including a frame;said first cargo-carrying unit including a chassis;a fifth wheel rigidly affixed flush within said frame;a kingpin affixed to the underside of said first cargo-carrying unit for engagement with said fifth wheel;a coupling unit rigidly affixed to the frame at the rearmost end of the power unit;a coupling unit rigidly affixed to said chassis;whereby joining said coupling units and engagement of said kingpin with said fifth wheel affixes the first cargo-carrying unit on the power unit.

Abstract: In a cargo-carrying vehicle having a power unit, a first cargo-carrying unit releasably affixed to the power unit, the first cargo-carrying unit not being pivotal on the power unit, and a second cargo-carrying unit releasably and pivotally connected to the first cargo-carrying unit, wherein the improvement comprises:a folding door including a first and second halves, each half having a first and a second section, a plurality of hinges mounting said first section to said cargo unit, a hinge mounting said first section to said second section, a predetermined distance between the first and second cargo-carrying unit, said first section having a width less than the predetermined distance.

Abstract: A method for manufacturing a refrigerating system. According to the method, adhesive is applied either to outer faces of an intermediate insulating body or to inner faces of a pair of outer metal skins which are to engage the outer faces of the insulating body to form a wall structure therewith, or to all of these faces. Evaporator and condenser coils are introduced into grooves of the insulating body at opposed faces thereof so as to directly engage the metal skins. These coils may be introduced either before or after the application of the adhesive. Then after the skins are applied to the assembly of the insulating body and coils, the assembled insulating body, coils, and skins are situated in an evacuated atmosphere for eliminating any air bubbles in the adhesive while tightly pressing the metal skins against the insulating body and coils.
