The pipe or tube is spot heated and bent at that heated spot into a desired toy shape, and one toy shape is has the pipe or tube ends aligned and are joined, providing a toy with an open center area that is suitable as a bird perch and is fitted with a hanger for suspending it and may be drilled to receive a cord or cords fitted therethrough that toy pieces, such as sections of colored wood, plastic or other materials, are threaded on.

Abstract: A marble and granite nipping tool that includes a pair of blade support plates as blade mounting ends whereto nipping blades having opposing nipping edges are releasably mounted and provides for setting a selected opposing nipping edge spacing to allow a use of the tool on different widths or thicknesses of marble and granite slabs, for removing or nipping off edge sections thereof. The tool includes a linkage consisting of lever arms secured at lever arm ends to the blade support plates undersurfaces that connect, in turn, through a pivot coupling to scissoring arms that and operated to provide a mechanical advantage to multiply a closure force directed through the scissoring arms and linkage and into the blade support plates for facilitating the removal of marble and granite edge sections. Which scissoring arms can, in one embodiment, be manually closed by an operator moving ends of the arms together, and, in another embodiment, by operation of a an automated scissoring arm closure arrangement.

Abstract: A water structure formed from at least a pair of sleeves from a puncture resistant flexible material joined along common longitudinal surfaces, as by sewing, and include sleeve ends that are formed into closed to maintain closed-off ends of water filled tubes, and including an arrangement, such as an outer sleeve, for maintaining the pair of sleeves in side by side relationship and/or may includes at least one ground sheet for anchoring the water structure.

Abstract: A folding floor mat that is formed from a plurality of panels formed from a resilient polymeric material and having a work surface and a grip surface. Flexible hinge assemblies foldably join at least two of the panels along a fold boundary, which preferably incorporates a plurality of channels that are integrally formed in the work and grip surfaces. More preferably, the channels are laterally spaced apart about the grip and or work sides. Even more preferably, the channel or channels formed in the work surface are staggered relative to the channel or channels formed in the grip surface. Also, each channel is ideally shaped to optimize relief internal material stresses of the polymeric material during and after it has been folded.

Abstract: The invention is in a regulator and converter operated to fumigate a volatile material, preferably a liquified petroleum gas (LPG), under vacuum, into an intake air flow of an internal combustion diesel engine to provide, on demand generated by an operator closing a throttle, passage of LPG to the regulator and converter wherein it is vaporized and the LPG vapors are passed into the engine intake air flow that travels into the engine. The injection of LPG vapors provides for an increase in engine output power and an improvement in fuel percentage of burn. The regulator and converter is connected the engine coolant system to receive a hot coolant flow, heating an LPG flow path therethrough to vaporize the LPG with the LPG vapors then directed from the regulator and converter into the engine intake air flow.

Abstract: A run flat tire that includes a tire casing and an inner support fitted within which tire casing, with the inner support to support the tire casing load upon run flat tire deflation. The tire casing and inner support are for mounting to a rim, the tire casing side wall bead ends to fit against side wall ends of the inner support that are maintained against rim interior stepped sections. The inner support is formed from an elastomeric material, preferably by casting or molding methods, to include an interior arch shaped cavity centered under the inner support outer surface having at least one hundred forty (140) degrees and not more than one hundred eighty (180) degrees of arc, and has a uniform thickness between the inner support inner and outer surfaces that is selected to support a particular anticipated load, after tire deflation, to support, in compression, the tire load for a target distance and speed.

Abstract: A dust director portable vacuum guard for mounting onto a bore of a portable angle grinder. The dust director includes a housing with parallel inner and outer walls and an end web adjacent to a straight barrel that is secured along aligned edges of the walls. The barrel is slotted from a forward dust collected end to the web and is stepped at a selected distance apart from the inner wall upper edge, functioning as a baffle. An attachment ring is pivotally mounted in the housing inner wall to releasably couple to an angle grinder bore and pivot around that bore upon release of a spring loaded thumb screw. An extension cover is included on an end of the housing to allow for sawing through a corner.

Abstract: A cushioning hand grip formed from a polymer material having a vio-elastic character whereby the grip will exhibit nearly perfect (less than two (2) percent of an applied force only is not cushioned) recovery or compression set, provides, even when wet, a tacky surface that will adhere to an operators hand closed therearound and, additionally, provides a non-slip adherence to a handle bar end whereover the grip is fitted. The grip is formed as a cylinder that may include a liner, such as a nylon sleeve, wherearound the grip is formed, and preferably includes an end cap arranged for locking into a handle bar end, maintaining the grip fitted onto that handle bar. For ease of gripping the grip outer cylindrical surface includes lateral and longitudinal rows of spaced dimples formed therein, with grooves between which dimples for channeling water or allowing as air flow to pass therethrough.

The hub includes separate bearing systems for supporting, respectively, radial loads as perpendicular to a road surface, and axial loads as are side loads directed into the hub. The separate bearing systems include a pair of radial bearings for supporting radial loads, with each radial bearing of the pair mounted at each hub end to receive an axle fitted therethrough, and a pair of thrust bearings for supporting axial loads, with each thrust bearing of the pair mounted at a hub end, between the radial bearings outer surfaces and an axle mounting to a frame.

Abstract: A water structure formed from at least one flexible tube or sleeve, that functions as a water containment vessel when at least partially filled with water and closed at its ends, and includes a rope positioned therein. The rope is for connection, on one end, to a second flexible tube or sleeve and is for use in pulling the second flexible tube or sleeve through the first tube or sleeve. The second tube is then to receive a volume of water therein, that expands the second tube against the first tube inner surface to function as a water structure.
