Abstract: A grate bar is provided for use in forming a grate bar assembly of a sintering pallet car. The grate bar comprises an elongate body having top surface for receiving a load, a pair of opposed arms, and a pair of opposed feet, with each arm and foot pair retaining the frame of the car therebetween. Each of a pair of peripheral spacers extends laterally away from the body to distance the body from a body of an adjacent grate bar. Each of a pair of central spacers is located between the peripheral spacers and extends laterally away from the body to distance the body from the body of the adjacent grate bar. At least one of the plane defined by a peripheral spacer top wall and the plane defined by a central spacer top wall is below the plane defined by the top surface of the elongate body.

Abstract: The invention relates to a sidewall for use in a sintering pallet car. The sidewall has a base for connection to a frame of the pallet car and a wall extending upwardly from the base to a top. The wall has opposing ends, opposing interior and exterior faces, and a height as measured from the base to the top. An elongate brace is disposed on the exterior face intermediate of the opposing ends, the brace extending downwards from the top towards the base. The sidewall may include an arcuate protrusion disposed on the interior face intermediate the opposing ends of the sidewall or a cap extending between the opposing ends of the sidewall and joining the exterior and interior faces, the cap having a protruding lip extending from the exterior face. The sidewall may comprise a top segment and a bottom segment, releasably securable to each other.

Abstract: The combination of a jack stand and a vertically oriented, compact hydraulic jack enables a user to avoid misplacement when lifting a load. The stand includes a vertically oriented column moveable between a plurality of different elevated positions. An underside of an overhanging member attached to the column is engaged by a piston member of the jack to elevated the column as the jack is elevated.

Abstract: A jacking system is disclosed in which a hydraulic jack, having a raisable piston, is used, in combination with a jack stand having a raisable support column, to raise a load. In a preferred embodiment, the support column has two components that may telescope into each other and that may be held in fixed position by two ratchet mechanisms. The jack stand is configured so that, when the hydraulic jack is positioned alongside the jack stand, the piston of the hydraulic jack is able to interact with and raise the support column along with the load.

Abstract: A hydraulic jack system is described, suitable for lifting heavy loads such as automobiles. The jack system is operable by a powered driver fitted with a socket for coupling to a nut rotationally fixed to the jack system, wherein the driver is removable directly after use. As such, no handle is required for activating the hydraulic jack system. The jack system has a low profile, reducing the danger of being accidentally knocked into during operation. When operated by a powered driver, the driver rotates a camshaft mounted to the jack system, the camshaft reciprocally drives a push rod that activates a plunger for hydraulically elevating a piston ram.

Abstract: A tape measure device has an elongated blade with a central concave-convex segment with at least one planar segment adjoining edgewise the central concave-convex segment to form a junction that extends substantially along the entire length of the elongated blade. During formation of the blade the junction is annealed to avoid formation of a flaw or incipient fracture along the junction.

Abstract: A tool includes a pair of spaced apart substantially parallel arms carrying a mounting member to which are detachably connected axially oriented driver and drill elements. The mounting member is moveable along the arms reciprocally between a first position where it is manually rotated to select the axial orientation of the driver and drill elements and a second locked position to hold the driver and drill elements in a selected axial orientation until the mounting member is return to the first position. The locking function is provided by a spring element actuated upon the mounting member being moved from the first position to the second position to apply pressure against the mounting member while in the second position.

Abstract: A tool adapted to be coupled to a power drill includes a multi-component bit mounted to reverse positions so that in one position its drill element drills a hole and in another position its driver element drives in a fastener.

Abstract: Pliers having, for example, needle-nose and blunt-nose heads are manipulated using handles connected to pivot and move between a needle-nose head, grip-ready, position and a blunt-nose head, grip-ready, position. Each handle has a stop member having two faces. One face of each stop member is adapted to abut a needle-nose head and the other face is adapted to abut a blunt-nose head.

Abstract: A method and device is disclosed for displaying a plurality of tools on a point-of-sale display. The device may comprises a pair of support members, each retaining a tool such that one tool partially obscures the other while allowing a customer to properly identify each tool.
