  • Patent number: 4577883
    Abstract: A vehicle tow bar comprises a longitudinally extending, tubular cross bar mounted laterally across the front of the vehicle to be towed, the cross bar mounting for longitudinal movement thereon, pivotal rotation thereabout, and laterally pivotal movement relative thereto, a longitudinally extensible, two section telescoping reach having a hitch coupler mounted on its forwardmost end arranged for connection to an associated hitch ball component on a tow vehicle. A pair of tow chains connect opposite longitudinal ends of the cross bar to the forwardmost end of the reach and are arranged to become taut when the reach is extended to a desired maximum length. A locking screw on the rear section of the reach releasably engages the forward section of the reach to move the latter forwardly in order to tension the chains attached thereto and to prevent inward collapsing of the telescoping sections.

  • Patent number: 4549663
    Abstract: A trailer frame storage system comprises a plurality of storage units connected closely together in laterally spaced apart condition, each storage unit having a plurality of longitudinally spaced, folding trailer frame support arms each arranged to receive and support a trailer frame for storage in a substantially vertical position in which the trailer frame is rested on its rear end on the ground and its forward end extends upwardly. Each arm is extended, one at a time from rear to front, by movement of the next rearward arm to fully extended position as a trailer frame is rested against it, the frames being transported longitudinally into the storage unit, successively filling the unit from the rear end to the front end. Removal of the stored trailer frames follows the reverse order, and removal of each frame results in it engaging the next adjacent forward arm from which a trailer frame has been removed, to cause said forward arm to be moved toward retracted position.

  • Patent number: 4546226
    Abstract: Particulate dielectric material is processed by radio frequency (RF) energy while being simultaneously conveyed from an inlet to an outlet, by disposing the transmitting and receiving electrodes of an RF generator diametrically opposite each other on the outside of a conveyor tube containing a screw conveyor, both the tube and screw being made of dielectric material. A fiberoptic probe is located at one end to sense the temperature of the particulate material in the conveyor tube and is connected at the opposite end to an infrared sensor which provides an electric output signal proportional to the sensed temperature. This output signal is coupled to a set point controller which provides an electric output signal representing a small temperature range above and below a selected set point temperature, and the latter output signal is coupled to a duty cycle regulator which operates to regulate the "on" time of the RF generator.

  • Patent number: 4525119
    Abstract: A wheeled vehicle mounts a rotary framework providing a plurality of longitudinally extending, peripheral and inner compartments for the removable storage of a multiplicity of hay bales or like objects. The framework is rotated by a driven endless chain wrapped about the framework centrally of the longitudinal ends thereof. Communication between the peripheral and inner compartments is controlled by movable gates operated selectively by spring-loaded latching mechanism at predetermined intervals of rotation of the framework. A longitudinally extending, reversibly movable feed conveyor below the framework registers with each of the peripheral compartments selectively for moving bales to and from the compartments. The arcuate shields extend from the opposite sides of the feed conveyor upwardly to form with the latter a semicircular shield surrounding the lower half of the framework to confine the bales in the lower peripheral compartments.

  • Patent number: 4500381
    Abstract: Multiple ply corrugated or solid fibre paperboard having any desired number of plies is made by adding to the delivery end of conventional corrugator or paster apparatus, between the cut-off section and the stacker section, a glue applicator system controlled, preferably by computer program, to apply glue only to the desired areas of those outfeeding paperboard sheets which are to be bonded together to form the desired multiple ply paperboard. The glued and unglued paperboard sheets proceed to the stacker section where they are stacked one upon another. The paperboard sheets having an interface of glue are bonded together to form the multiple ply end product and the paperboard sheets having no glue interface allow subsequent separation of the plurality of multiple ply corrugated paperboard end products in the stack. Offsetter mechanism is provided to offset corresponding margins of certain plies of a group before depositing them in the stacker, to form a splice joint.

  • Patent number: 4473345
    Abstract: An inlet gas pressure passageway is associated with the movable mold section of a molding press and terminates at and therefore in the plane of the surface of said movable mold section which confronts the surface of the fixed mold section of the press. An outlet gas pressure passageway is associated with the fixed mold section and terminates at and therefore in the plane of the surface of said fixed mold section in alignment with the inlet passageway opening. Air or other gas under a predetermined superatmospheric is applied to the inlet passageway for delivery to the outlet passageway, and the latter is connected to a pressure switch operable at said predetermined gas pressure to effect application of high hydraulic closing pressure to the movable mold section.
