  • Patent number: 6698806
    Abstract: An elongated channel protector has an end wall that precludes axial displacement of the protector along an elongated rail car plug door operating handle in one direction. Angle shaped members extend from the protector laterally for engaging a cover appurtenance on the door for precluding axial displacement of the protector in the opposite direction. A pair of legs depend from the protector side walls and have aligned holes for receiving a bolt seal. Tubular elements surround the holes to protect the seal head and locking body. The seal is seated beneath the handle which is covered by the protector locking the protector to the handle.

  • Patent number: 6308840
    Abstract: A golf club holder suspends golf clubs beneath an umbrella to keep the grips dry during rain. The holder comprises a head with clip devices for attachment to an umbrella shank and for attaching the shafts of clubs upside down to the holder. The clip devices comprise in one embodiment a molded plastic head with receptacles for attachment to the umbrella shank and for receiving the club shafts, the receptacles each comprising a bore lined with high friction rubber and a slot for receiving the shank or shafts laterally into the receptacle. A stem extends from the head to provide enhanced gripping action to the umbrella shank. The devices may be hinged to the stem to permit the holder to remain with the umbrella shank so that the umbrella may be collapsed with the holder attached. The holder stem may be permanently attached to the umbrella shank with the shaft clip devices hinged to the stem.

  • Patent number: 6265973
    Abstract: A molded transparent thermoplastic housing has a programmable transmitting circuit for transmitting seal identifying serial number, seal location, container identification and other data to a local receiver. A door in the housing permits access to the circuit for programming the seal indicia and related data for transmission. A contact arrangement forms a switch upon insertion of a locking bolt into a locking mechanism in the housing and applies battery power through the bolt to activate the data generating circuit. A conductor along the bolt shank is connected to the circuit provides a tamper evident signal to the circuit when the bolt is severed. The circuit senses the removal of the bolt or severed bolt condition for generating a “tamper” signal which is transmitted to a local receiver/reader.

  • Patent number: 6182877
    Abstract: A cane with an arm cuff C-clamp and a lateral handle has an accessory article carrying sack comprising a cloth or other material drawstring sack attached to the C clamp with a loop of the drawstring. Clips attach the sack to the leg of the cane to hold the open bag top closed and to keep the sack from moving about as the person using the accessory walks. Various embodiments of clips and fasteners are disclosed for attaching the sack to the cane leg and for precluding lateral displacement of the sack during walking of the user.

  • Patent number: 5328948
    Abstract: A composition comprising a halopolymer, such as an ethylene/chlorotrifluoroethylene copolymer, an effective stabilizing amount of an ionomer, and an effective stabilizing amount of a compound such as a phosphite of an organic polyhydric phenol; a thioester; a phosphite; or a hindered phenolic antioxidant. Preferred ionomers are metal salts of ethylene-acrylic acid copolymers, and metal salts of sulfonated polystyrenes. The stabilized halopolymers have improved resistance to thermal degradation and suffer less discoloration when subjected to high melt processing or extrusion molding temperatures.

  • Patent number: 5195609
    Abstract: A retractable step is movable from a position located in a cavity to an extended position located outside of the cavity. The invention provides for a latching facility to hold the step in the extended position against the bias of a retracting spring. A person standing on the step, exerting a downward force thereon disengages the latching facility. As the downward force is removed from the step, the step automatically retracts in response to the bias of the retracting spring.
