  • Patent number: 6575781
    Abstract: A power cord securing device is installed within a housing of an electrical appliance for securing a power cord. The power cord securing device includes a rotatable plate having a first part for being wound by the power cord, and a resilience element having a first terminal and a second terminal respectively connected to a second part and a third part of the rotatable plate. When the power cord is stretched, the rotatable plate is forced to rotate in a first direction and allow the resilience element to result in an counterforce, and when the counterforce is relieved, the rotatable plate rotates in a second direction opposite to the first direction.

  • Patent number: 5527506
    Abstract: The invention discloses a composition and method for the enhancement of polyguanide based water sanitizing systems and for conversion of such systems to alternative water sanitizing systems if desired. The method includes the addition of an enhancing or conversion agent selected from the group consisting of a halogen salt, a Bromohydantoin and a chlorobromohydantoin in an amount to provide a concentration of approximately from 1 to 50 parts per million. Sodium borate and/or polyphosphate may also be added to the system to improve the effectiveness of the enhancing agent. The system may be converted to an alternative water sanitizing system by the addition of a sanitizing agent selected from the group consisting of chlorine, copper, silver, quaternary ammonium compounds, and polyquaternary ammonium compounds, which may be released into the water at a rate of 0.01 to 1 ounces per hour per 10,000 gallons of water for a period until conversion is complete.

  • Patent number: 5439256
    Abstract: A bulkhead fitting for draining fluids off the topside of a thin flexible barrier cover (31), comprising: a male threaded member (1), a female threaded member (11), and an o-ring seal (21). The male threaded member (1) has a male threaded spout (4), and a wide flange (2) that extends outward from the top end of the male threaded spout (4). The wide flange (2) rests on the topside of the barrier (31) and the male threaded spout (4) extends through an opening made in the barrier (31). The wide flange (2) distributes the weight of the fitting over the surface of the barrier (31), so that the barrier (31) can support the fitting. The female threaded member (11) has a female threaded spout (15), and a seal supporting flange (12) extending outward from the top end of the female threaded spout (15). The female threaded spout (15) threads onto the male threaded spout (4) from the underside of the barrier (31).

  • Patent number: 5431074
    Abstract: The present invention is directed to a device for removing lug nuts from the axles of vehicles. The improvement comprising a stabilization platform having four legs with at least one of the legs having an incline edge which has at least one retaining means or notch formed therein. The platform interacts with a torque tool having a socket arm with a lug nut socket at one end and an extension arm secured at a right angle to the socket arm. When the socket engages a lug nut, the socket arm is placed within the retaining means and the extension arm is actuated to remove or tighten the lug nut.

  • Patent number: 5254526
    Abstract: The invention discloses an anti-microbial composition, and method for its use for the long term inhibition of the growth of algae in swimming pools, spas, and similar bodies of water. The method includes the addition of bromide ions to the body of water in amounts sufficient to provide a concentration of bromine of approximately 0.1 to 100 ppm. A polyphosphate is premixed with the source of bromide ions in a ratio of from 5 to 15 weight parts polyphosphate to each 100 weight parts of said source of bromide ions. A chlorine containing oxidizer is added to the water in a amount sufficient to oxidize the bromide ions to bromine and provide a concentration of chlorine containing oxidizer of approximately 0.2 to 10 ppm to safely sterilize the water.
