Abstract: An activation device useful for drag racers comprising a body, a trigger, a cocking pressure spring plunger set screw, a trigger tension spring plunger set screw, a trigger tension jam nut, a body cover, cocking safety button, screws, a microswitch, a wave washer, and a trigger set screw. The body comprises a trigger pivot post, a wiring channel, a wiring aperture, and a recess surface. The trigger comprises a trigger pivot post aperture, a trigger released position notch, a trigger cocked position notch, and a cocking channel.

Abstract: A disclosed method of downhole tool system development comprises: receiving specifications of a downhole tool system that comprises multiple strings, each string having one or more components; and checking for interference between the multiple strings in an initial position. A disclosed system comprises: a memory that stores software; and a processor coupled to the memory to execute the software. The software causes the processor to provide a graphical user interface that enables a user to specify a downhole tool system having multiple strings, and to test the strings for diametrical overlap attributable to relative motion of the strings.

Abstract: A heat tolerant, pressure resistant elastomeric composition comprising a blend of a first ethylene-vinyl ester copolymer and a second copolymer selected from the group consisting of chlorosulfonated polyethylene (CSM), chlorinated polyethylene (CPE), polychloroprene (CR), ethylene-acrylic elastomer (AEM), alkyl-acrylate copolymer (ACM), polyvinyl acetate (PVA), nitrile-butadiene rubber (NBR), hydrogenated nitrile-butadiene rubber (HNBR), and mixtures thereof; a hose manufactured therefrom; and a method for preparing the hose are described.

Abstract: A vinyl ester composition; a tubular structure such as a hose for conveying fluids in an automotive engine cooler, transmission oil cooler, power transmission cooler, radiator or heater; and a method for preparing the tubular structure are described. The tubular structure includes a single layer of a heat tolerant, pressure resistant, hydrocarbon fluid impermeable composition comprising a copolymer of a first vinyl ester and a second vinyl ester, and one or more additives. The composition may, optionally contain a second polymeric component such as an ethylene-vinyl ester of a C2 to C6 carboxylic acid, chlorinated polyolefins, chlorosulfonated polyolefins, polychloroprene, ethylene-acrylic rubber, alkyl acrylate copolymer, polyvinyl acetate, acrylonitrile-butadiene rubber, hydrogenated acrylonitrile-butadiene rubber, ethylene-propylene-diene terpolymer, styrene-butadiene rubber, ethylene-propylene rubber, butyl rubber, cis-polybutadiene, cis-polyisoprene, polyurethane, polyamide and combinations thereof.

Abstract: A vulcanized tubular structure for conveying fluids in an automotive engine cooler, transmission oil cooler, power transmission cooler, radiator or heater; and a method for preparing the tubular structure are described. The tubular structure includes a single layer of a heat tolerant, pressure resistant, hydrocarbon fluid impermeable composition comprising a copolymer containing at least one vinyl ester having incorporated therein one or more additives. Preferably the copolymer is an ethylene-vinyl acetate copolymer.

Abstract: Methods of expanding well tools, which permit operation of the well tools after expansion, are provided. In a described example, a cementing tool includes a valve and a packer. After the cementing tool is expanded, the valve is selectively opened and closed, and the packer is sealingly engaged in a wellbore.

Abstract: A pad dispensing device includes a receptacle having a dispensing slot in its top wall and a stack of pads contained in the receptacle, the pads being interconnected by elongated pull tabs having transverse lines of weakness at their junctions with the leading pads. The stack of pads is formed of a continuous web including longitudinally spaced pads which may be circular or other shapes, successive pads being connected by intervening elongated tabs, and the web being accordian folded to superimpose the pads. The pads are impregnated with an active ingredient. The leading tab projects through the dispensing slot and as a pad is withdrawn the next pull tab is exposed.
