Abstract: Emergency springs are disposed within air springs which are used for normally supporting a railway car body. When the air springs fail, the car body is supported by the emergency springs. Each of the emergency springs includes a conventional spring in combination with a pair of angularly disposed springs which changes operating chracteristics when the load is increased.
Abstract: A four passenger automobile frame includes a main platform and an open frame secured thereto for receiving panels thereon. Energy absorbing means are included in pairs of forwardly and rearwardly extending side rails which are connected from the platform to front and rear bumpers.
Abstract: A main tubular support structure extends along the length of a plurality of curved solar panels. Integral support sheet members are curved to receive the panels on one side. The opposite side of the sheet members include projecting sections welded to the tubular structure.
Abstract: A first set of selectively movable platens are disposed at a fixed station to receive a container therein to provide shoring of the external surfaces of the container. A second set of selectively movable platens are disposed to provide shoring of the internal surfaces of the container. Expandible and retractable slat members connect the upper corner portions of the second set of platens so that when these platens expand, the slat members provide internal shoring at the inside corners of the container.
Abstract: A hitch mechanism connected to a freight car is disposed to receive a king pin of a trailer to be carried by the car. The hitch mechanism is adapted to be selectively opened to receive the king pin therein and then closed by a lever to secure the king pin in place. A latch mechanism automatically locks the hitch mechanism in a closed position after the hitch mechanism is closed. A manual operation of the latch mechanism is required before the hitch mechanism can be opened.
Abstract: A source of relatively high air pressure is connected to a pressure regulator which provides a lower relatively uniform predetermined pressure to a plurality of tires on wheels of a vehicle. If the pressure in any one of the tires drop below the others, the pressure from the regulator automatically brings it up to the uniform pressure.
Abstract: Transfer apparatus is adapted to receive a mechanical part from a die and transfer it to a subsequent die. The apparatus may be movably aligned in place and includes means for aligning the part received from the first die and position it to permit transfer to the subsequent die.
Abstract: A support structure for supporting a plurality of solar reflectors include a truss structure having a plurality of bar elements welded together to provide strength and rigidity. Longitudinal connector elements are connected to the truss element to permit attachment to the aligned closely disposed reflector panels. A receiver element with means for compensating for dimensional changes is also attached to the support structure. A pedestal disposed at each end of the support structure is adapted to receive and hold the truss structure with the attached panels and receiver. The entire support structure is adapted to be rotatable in the pedestal structure about 360.degree..
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: A wire raceway for attachment under the floor of a railway car includes a plurality of spaced hangers connected to the floor and disposed to receive wires or cables thereon. A cover including a plurality of sections extending along the raceway is adapted to cover and protect the wires after installation. Joint butt supporting straps are connected at the ends of the sections of the cover to hold the sections in place against the hangers.
Abstract: An anti-locking system controls the service braking pressure for controlling the application of pneumatic braking pressure applied to a wheel vehicle. A valve responsive to the speed of the wheel causes actuation of a fluid pulse generator to generate fluid pulses of predetermined amplitudes and frequency to switch the braking pressure on and off when the vehicle wheel becomes locked.
Abstract: A first set of selectively movable platens are disposed at a fixed station to receive a container therein to provide shoring of the external surfaces of the container. A second set of selectively movable platens to provide shoring of the internal surfaces of the container are attached to a movable assembly which is normally disposed on a support platform at a second station. The assembly is selectively moved off and on the support platform in and out of the container to bring the second set of platens into alignment with the interior surfaces of the container.
Abstract: A secondary suspension system includes a pair of air springs connected between the bolster of a truck and the car body. The air springs are disposed at angles extending inwardly from opposite ends of the bolster towards the center of the car body to provide both vertical and lateral suspension for the car body.
Abstract: A fastener for retaining two adjacent edges of a pair of panels against the surface of a structure includes a head with an eccentrically disposed stem extending therefrom. A flange section around the stem is spaced from the head. Projecting sections extend from the stem below the flange. The projecting sections extend through an opening in the surface of the structure and retains the fastener therein.
Abstract: A guard beam is disposed below the bottom of the rear end of a trailer or truck. Energy absorbing members are connected between the trailer and the guard beam. When impact forces applied to the guard beam exceed predetermined minimum levels, the guard beam collapses and energy is absorbed in the absorbing members during the collapse of the beam.
Abstract: A side bearing comprises integrally bonded pieces including an elastomeric cushion member secured to top and bottom plates and flexible leveling means secured to the bottom plate. The bearing is designed for connection between the bolster and truck side frames of a railway car. The elastomeric member includes progressively larger openings therein extending from its center to its ends to provide varying flexibility to permit articulation of the truck side frames relative to the bolster during operation.
Abstract: A tilt system for a railway car includes mechanism for tilting the car only when lateral acceleration forces exceed preselected minimum levels and to limit the amount of tilting of the car.
Abstract: A basic truck for a railway car includes a pair of side frames connected by suitable transverse disposed members. Standard structural members for holding different types of suspension and journal bearings of the car are provided and are secured to the end of the side frames at predetermined locations dependent upon the types of suspension and journal bearings used. Gusset members designed in accordance with the operating car requirements are connected to provide the principal structural connections between the mountings and the side frames.
Abstract: This invention relates to an improved, matured, moldable flame resistant, thermosetting polyester resin system which includes two different polyester resin compositions. One of the resins is a relatively fast reactive resin and generally contains a minor amount of isophthalic acid and a second, slower reactive system devoid of such acid. The resin system includes suitable flame retardant or flame extinguishing compounds including antimony trioxide and a halogenated organic compound. Also present are inert filler materials such as reinforcing fibers or inert, inorganic materials.
Abstract: A swingable impact tool and a method of making it wherein the tool has a metal head fastened both chemically and mechanically to a handle made of a composite of materials including a pultrusion of fiberglass filaments in a matrix of polymerized thermosetting resin covered by elastomeric urethane form which protects the core member from impact loads and absorbs the transfer of shock loads to the hands of the user. Metal or plastic members are used to reinforce critical areas of the handle adjacent the head and the stem member disposed within the socket in the head.
