  • Patent number: 5650060
    Abstract: An ionically conductive agent having means for reducing passivation of metal subject to anodic dissolution is disclosed. The ionically conductive agent is interposed between metal to be protected from corrosion and metal to be sacrificed to provide cathodic protection. An electrical connection between the two metals completes a galvanic circuit. The means for reducing passivation can be either a complexing agent for ions of the metal to be sacrificed or can be a membrane to inhibit flow of ions that would affect the ability of the ionically conductive medium to support continued anodic metal dissolution. The ionically conductive agent and a system for cathodic protection using the ionically conductive agent is particularly suitable for a galvanic circuit to cathodically protect reinforcement bars in concrete structures such as transportation bridges, transportation highways, parking facilities, and balconies exposed to corrosive environments.

  • Patent number: 5603207
    Abstract: Apparatus for making decorative crafts ropes including a hand-held motorized strand twisting unit and an improved method for rigging, anchoring and spreading strands. Strand twisting unit includes a frame or housing, hand grip, electrical circuit, motor, drive mechanism and twisting hooks. In the rigging process, twisting hooks are aligned and interspaced with a series of anchoring hooks on a strand anchoring unit so as to capture or snag two or more strand segments in a single motion.

  • Patent number: 5240256
    Abstract: Tethered ball and receptacle toy incorporating a tethered ball, one or more catcher loops, and a revolving frame adapted to be spun in relation to one or more rotating handles. Revolving frame (20) includes rod (22), catcher loops (48), handle mounts (24) and tether anchor (37). Catcher loops (48) incorporate an aperture (50) just large enough to receive ball (46) in a nested fashion. Handle mounts (24) include handle receiving holes (34) which receive rotating handles (26) with grip (28), axle (30), and hub (32).

  • Patent number: 5147236
    Abstract: Levered whirligig of the string torsion variety which employs the forces generated by contraction of string torsion device (26) to actuate an articulated frame (10). Articulated frame (10) includes levers (12) and upper struts (18). Levers (12) including handles (16), fulcrums (11) lower struts (14) and hooking member (22) with notches (24). Upper and lower struts are joined together at hinged joints (20), thereby providing an enclosed, articulated frame easily manipulated using a variety of methods. String torsion device (26) includes intertwistable strands (28) and spinning member (30).

  • Patent number: 4998724
    Abstract: Improved apparatus for playing a game of thumb wrestling includes a stabilizing handle which employs forces generated by firmly interlocking fingers of players' hands to stabilize and anchor a game ring surface. Game ring surface includes holes through which the thumbs of opponents are inserted upwardly, and a solid wrestling region upon which one thumb can forcibly pin another thumb, thereby giving the realistic impression of a pin in wrestling.

  • Patent number: 4548862
    Abstract: Flexible tape having a pressure-sensitive adhesive layer containing particles, each particle having a ferromagnetic core and an electrically conductive surface. By virtue of the ferromagnetic cores, the particles can be magnetically attracted to form a large number of discrete electrically conductive bridges extending through the thickness of the adhesive layer. The tape can be used both to bond together and to electrically connect individual members of facing arrays of electrodes.
