  • Patent number: 6464192
    Abstract: A vehicle support apparatus includes lower and upper parallel plates connected by plural telescoping vertical supports. The upper plate is adapted to receive an elevated vehicle wheel and provide support therefor. Locking pins are spring-biased to a locked position wherein each pin is inserted in one of plural pairs of aligned apertures disposed in a spaced manner in a telescoping vertical support to maintain the telescoping members in fixed relative position. The vehicle is first lifted by a jack and the apparatus positioned so as to place one of the vehicle's wheels on the upper plate to support the vehicle. The jack is then removed from the vehicle, placed between the spaced, parallel lower and upper plates, and the upper plate and vehicle wheel are further raised using the jack, with the telescoping vertical support locked at the desired height either manually or automatically by the locking pins.

  • Patent number: 5008298
    Abstract: A process for producing expandable thermoplastic resin beads which comprises suspending in an aqueous medium interpolymer beads comprising a polyphenylene ether resin and a polymerized vinyl aromatic monomer such as styrene, polymerizing the vinyl aromatic monomer in the presence of a polymerization catalyst to interpolymerize the vinyl aromatic monomer with the polyphenylene ether and, optionally, adding a cross-linking agent, to form interpolymerized thermoplastic resin beads, and introducing a blowing agent under pressure into the thermoplastic resin beads. The resulting resin beads have excellent foamability and molding fusability, and a foamed shaped article having superior thermal stability can be prepared from these beads.
