    Abstract: A rotary sliding vane fluid pump having an open rotor and radially extended arms forming slots that support the radially extending vanes. The relative position of the vanes and the inlet and discharge ports provide sealing by the vanes to the pump housing whereas the surface of the rotor does not seal to the pump housing so that radial rotor clearance is not critical. The rotor can be manufactured and assembled at lower cost. The rotor shape uses a minimum of material so that it is lower in weight and gives good pressure loading of the vanes. The open rotor is without closed voids to allow quick draining of the pump.

    Abstract: A suspension system for the operator compartment of a mine vehicle suitable for working in underground mines having low head room. A pair of vertically extending guide tracks are rigidly secured to a frame member of the mine vehicle. Each of the track members has associated with it a roller bracket constructed so that all moving contact between the roller bracket and the guide track which guides it is a rolling contact. Each roller bracket includes a projecting stud member of substantial construction which passes through an opening in the rear wall of the operator compartment, the two stud members providing the only points of support for the operator compartment. The operator compartment normally rests on and slides over the floor of the mine and by this arrangement is free to move vertically up and down as the elevation of the mine floor changes or when the bottom of the operator compartment encounters obstacles or debris on the mine floor. One of the openings in the rear wall of the operator compartment is elongated to permit either end of the compartment to move in an arcuate path with respect to the other end so that the compartment may tilt from end to end as required and to prevent binding and sticking of the roller brackets as they move vertically on the guide tracks. Stop means and shock absorbing means are provided to limit movement of the roller brackets in the guide tracks and to cushion the shock transmitted to the operator when the roller brackets impact the stop means.

    Abstract: A tank with a circular horizontal cross-section, which expands and contracts in service, a tank support element on the tank and above the tank bottom extending horizontally around the tank and having a flat horizontal surface, a support base on which the tank support element flat horizontal surface rests in radial slidable contact, a horizontal collar member having a vertical or sloped circular face, a horizontal ring member having a vertical or sloped circular face, either the collar member or the ring member is joined to the tank and the other of the collar member or the ring member is joined to the support base, and the collar member vertical or sloped face is located around the ring vertical or sloped face, and restraining apparatus which prevents lateral movement of the tank when empty and at nonservice temperature. Desirably, at least the collar member circular face or the ring member circular face is insulated, and the faces are parallel to each other and matching for effecting surface-to-surface contact upon cooling of the tank, and at least the horizontal surface on the tank support element or the support base is insulated.

    Abstract: The present invention is an ergonomic safety work mat which includes a modular ergonomic wooden platform with a synthetic tapered marginal border. The purpose of this invention is to provide occupational workers with a therapeutic, forgiving work surface to protect them from the health risks of working, walking and standing on a concrete floor or common anti-fatigue mat used in many factories today. The wooden platform is raised off the floor to offer suspension, thus promoting a spring effect for absorbing and returning compression force resulting in reduced stress loads and compression force for people who work, walk or stand fort extended periods of time. This product is modular in design so that the tapered borders of separate modular sections connect for a snug fit. The vertical edges of the wood sections also have connection points that provide a leveling effect and further enhance the fit of the module sections.

    Abstract: An industrial symmetric pedal control system is provided which allows for ergonomically favorable operation by paired reciprocal control pedals which mirror an operator's right and left limbs. The reciprocal mirror control pedals allow operation of the same predetermined function within designated machinery by either the left or right foot of an operator, thus reducing fatigue while maintaining proper position at a particular workstation. Also included in the system is an ergonomically designed floor mat to provide the operator with more comfort and less fatigue while operating machinery.

    Abstract: A work mat on which a worker stands while operating a machine for comfort and for the purpose of easing of physical stress caused by standing on a non-compressible floor during a work day. The work mat includes a wooden platform with a peripheral synthetic border which tapers from the floor up to the top edge of the wooden platform. In addition, the synthetic border extends inward about one half inch under the peripheral edge of the wooden platform, thereby elevating the wooden platform above the floor. The wooden platform is therefore suspended over the floor and can flex up and down as a user walks on or stands on the mat, thereby absorbing some of the shock of walking and moving on the floor. The compressibility of the wooden platform adds to the comfort of the work mat as well.
