  • Patent number: 7097254
    Abstract: The present invention provides a height-adjustment mechanism for an armrest. In an embodiment, a height-adjustment mechanism for an armrest includes an integral one-piece leverage body, and an integral one-piece sleeve. In an embodiment, the integral one-piece sleeve has pivot seats formed on a pair of locking arms depending from a first wall of the sleeve. These parts may be made of low cost materials suitable for integrally forming their features in an injection-moulding operation. Various features built into these parts may provide a user with a sense of quality.

  • Publication number: 20060131944
    Abstract: A chair adjustment mechanism has a pin retaining member (as, for example, a sleeve) with a slot having two laterally spaced pin receptors. Each receptor is partially defined by a peripheral wall of the slot and is further defined by a spring finger that projects along side of the peripheral wall. With this arrangement, a pin may be received through the slot and into a longitudinal slot of a second member (as, for example, a J-bar), which longitudinal slot defines a rack. The pin receptors may be positioned such that with the pin in a first of the pin receptors, it is engaged by the rack. In consequence, the pin retaining member may be moved upwardly with respect to the second member by notching the pin over teeth of the rack against the urging of the spring finger. The top of the longitudinal slot may have a cam surface to cam the pin into the second pin receptor such that the pin is now spaced from the rack. This releases the pin retaining member to be lowered with respect to the second member.

  • Publication number: 20040091030
    Abstract: A process for refurbishing cable modems which are not compliant with DOCSIS 2.0 to create a cable modem which is compliant with DOCSIS 2.0 and which reuses many of the components and circuits of the non compliant target modem in the circuitry which is compliant with DOCSIS 2.0. A replacement circuit board is mounted on the PCB of the target modem and connected to predetermined points to replace the functionality that is not DOCSIS 2.0 compliant with functionality that is.

  • Publication number: 20040090291
    Abstract: A process for refurbishing analog set top tuner/decoders which are not compatible with digital cable to convert same into a digital set top tuner/decoder which can tune any channel on a digital cable system and convert the digital data received on that channel into a video signal. The process comprises forming a replacement circuit and mounting said replacement circuit on the motherboard of the target set top tuner/decoder and then making circuit breaks at the appropriate points on the motherboard of said target set top tuner/decoder and connecting the appropriate points on the replacement circuit to the appropriate circuit breaks to complete the conversion.

  • Patent number: 4171463
    Abstract: An electric cable assembly and method for protecting an electric cable assembly for rendering the cable repellent to rodent attacks. A non-lethal toxic chemical, such as lithium chloride, which produces lithium ions when dissolved in the saliva of an animal, is incorporated in an electric cable as either a layer within the electric cable assembly around the circumference and along the length of the cable assembly or by providing a coating on the surface of the electric cable assembly by spraying or painting thereon a mixture containing, for example, lithium chloride.
