Abstract: A tire comprising a pair of beads; a carcass ply having ends, each ends anchored to a respective bead; at least one belt ply extending circumferentially around the tire and disposed radially outward of the carcass ply; and a tread portion disposed radially outward of the belt ply. The tread portion has a plurality of tread ribs or blocks and at least one groove disposed between adjacent tread ribs or blocks. In one aspect of the invention, the tread portion is formed from first and second rubber portions. The second rubber portion has a hysteresis value greater than the first rubber portion and a modulus value less than first rubber portion. In another aspect of the present invention, the tread portion is formed from a first and second tread compound. The hysteresis value of the second tread compound is greater than the hysteresis value of the first tread compound and the modulus value of the first tread compound is less than the modulus value of the second tread compound.

Abstract: A quick adjusting arm for an envelope spreader includes a bar member mounted to an articulated arm of the envelope spreader and a sleeve with a hook installed on the bar member. The bar member has a plurality of adjusting holes to position the sleeve at a selected position. The sleeve includes a single positioning hole, and a quick release pin, for example, a spring ball pin, is inserted through the positioning hole and the selected adjusting hole.

Abstract: A tire having a pair of beads; a carcass ply having ends, each of the ends anchored to a respective one of the beads; at least one belt ply extending circumferentially around the tire and disposed radially outward of the carcass ply; and a tread layer disposed radially outward of the at least one belt ply and formed from a first tread compound. The tread layer has a plurality of tread ribs; at least one groove disposed between adjacent tread ribs; and a groove wall lining covering from the at least one groove. The groove wall lining is made from a second tread compound different than the first tread compound.

Abstract: A display/storage rack system for hangings. The hangings are each carried by an elongated hanging member. Commonly the hanging is draped over the elongated hanging member. The rack system is affixed to a vertical support surface and supports a first end of the elongated hanging member as a cantilever; with an optional fixed bracket device supporting a second end of the elongated hanging member for displaying the hangings. A plurality of pivotal support devices of the rack system include offset arms for supporting and displaying the hangings in the rack in spaced apart vertical planes so that they do not contact one another and their top edges are at a different elevation. Hangings are displayed so that a top portion of each hanging is visible from the front of the storage rack. A pivot support rod of the rack system supports the pivotal support devices so that it can be rotated about a pivotal axis of the rack system.

Abstract: The present invention provides a truck tire with a siping geometry to protect the main ribs of the tire's tread by delaying the onset of irregular wear and the growth thereof. The improved tire tread comprises a plurality of main ribs formed by grooves extending generally circumferentially around an outer surface of the tire forming a tread width for contacting the supporting surface. A plurality of sipes, positioned on both lateral edges of each one of the main ribs, provide protection for the main ribs to delay the onset of irregular wear. A pitch length and a sipe length are both selected to be within a certain range of values, as well as a ratio of the sipe length to the pitch length is selected. The sipes are preferably narrow in width having a maximum width dimension of about 0.40 millimeter.

Abstract: The present invention provides a disconnect tool with a pair of fixtures having a central tool aperture or bore. The fixtures of the tool are placed around a second fitting of a spring-lock® type connector of a tubular conduit or pipe to be disconnected along a tubular axis of the conduit. The fixtures also provide a cage aperture to receive a cage portion of a first fitting of the connector. A pair of annular projecting collars extend between the tool aperture and the cage apertures. A pair of handles each have a lever arm and a shaft that is rotationally retained in a cylindrical bore of a respective fixture. The shafts of the handles each have a cutout forming a prying surface exposed to the cage bore within the respective fixture. In a first operating mode the fixtures are displaced along the tubular axis so that the collars inter a chamber of the cage and contact a circular locking spring within the cage.

Abstract: The present invention provides a protector assembly or fence type structure that is easily installed along the sides of a dock where water craft are docked or attempting to become docked. The fence type structure protects the water craft as well as the dock from being damaged. The invention includes a frame with spaced apart vertical members supporting a horizontal array of vertically supported tubular roller members which rotate when contact is made with a water craft as it approaches the dock. The fence type structure is attached by a bracket to a top side area of the dock so that it hangs vertically and extends to a location near the surface of the water. The fence type structure can be rotated about the top bracket to a position up and out of the water for cleaning and repairing, as well as for removing debris which may have been trapped by the dock structure and the fence type structure of this invention.

Abstract: The present invention provides a pneumatic tire having a tread portion comprising a plurality of axially spaced apart essentially longitudinal grooves separating essentially longitudinal ribs. On at least one of said ribs, transverse grooves or cuts repeat in the circumferential direction to form first and second land portions wherein the first land portions comprise blocks having a circumferential length greater than that of the second land portions. Said second land portion acts as a sacrificial bridge which provides traction improvement and minimizes undesirable surface anomalies during the service life of the tire.
