Abstract: A machine tool for machining a molded part, such as an elastomeric coated valve component includes a rotatable cutting tool having a shape corresponding to the shape of a cavity of the valve component. A method of machining the molded part is also disclosed.

Abstract: A partial valve assembly includes a wedge and a disk assembly that is assembled with at least one covered insert assembly and at least one O-ring. The insert assembly is covered with ethylene propylene diene monomer (EPDM) rubber or is covered with at least one of the following materials: styrene-butadiene (SBR), nitrile, neoprene rubber, adhesive backed rubber, cork, cork-rubber, Buna-n rubber, Buna-s rubber, nylon, silicon sponge rubber, fiber board, leather, natural rubber, synthetic rubber, plastic, polypropylene, polystyrene, thermoplastic elastomer (TPE), polyurethane, silicone, Teflon, urethane, and the like.

Abstract: A latch for releaseably securing one body portion, such as a hood, to another body portion, such as a cowl, of a semi-tractor or the like. One of the body portions has a hook member mounted thereon and the other carrys a securing device. The latch is of one-piece molded construction comprising an elongate elastomeric member having a handle at one end, an opening therein adjacent the handle and a tongue in the opening extending from the handle toward the other end, the handle and tongue being integral with the elongate member. The free end of the tongue is adapted for engaging the hook member, and an opening is provided at the other end of the elongate member for connection to the securing device. The free end of the tongue is spaced from the opening a distance less than the distance the hook member is spaced from the securing device when the two body portions are adjacent one another and the elongate member is untensioned.

Abstract: A coupling hose assembly with a flexible hose and two clamps each bonded for only a minor portion of the length thereof to the hose, each positioned adjacent an end portion of the hose. Ridges are formed in the hose on each side of each clamp to guide each clamp as it is being tightened. The inside of the hose is provided with a circumferential bead against which the ends of tubular members can be positioned so that they are inserted sufficiently in the hose so as to be in proper registry with the clamps, thereby ensuring that when the clamps are tightened they will constrict the hose uniformly about the tubular members to produce seals therebetween.
