Abstract: A material not releasing gaseous organic substances during use is used as a filter medium and a sealing material for tightly sealing between the medium and a frame. Specifically, a synthetic paraffin not containing an aliphatic hydrocarbon having not more than 19 carbon atoms or less is used as a non-silicone type water repellent contained in a treatment agent for forming fibers into a cloth-like filter medium. A carboxylic acid ester having 400 or more molecular weight is used as a plasticizer and a phenolic compound having 300 or more molecular weight is used as an antioxidant to be added to the treatment agent and the sealing material. This enables that the gaseous organic substances are not present in a clean room, a semiconductor production apparatus or the like.

Abstract: A fluid coupling apparatus for communicating fluid between a fluid hose and a heat exchanger wherein the fluid coupling apparatus minimizes or eliminates the spacing required or necessitated from the bending of a fluid hose.

Abstract: A spray painting apparatus and methodology. A plurality of parts are loaded onto a carrier at circumferentially spaced locations about a central spin axis of the carrier whereafter the carrier is moved in indexing fashion to a spray station where drive means engage the carrier to spin the carrier about its spin axis while a spray gun assembly is moved up and down in reciprocal fashion parallel to the spin axis. The parts are mounted on the carrier in a fashion to simulate impellers which have the effect of sucking air into the center region of the carrier to augment painting of the interior surfaces of the parts. The carriers are preferably moved to the paint spray station by a power and free conveyor system wherein the carrier is disengaged from the power conveyor at the paint spray station and is reengaged with the power conveyor following spinning movement of the carrier and reciprocal movement of the spray gun assembly.

A gasket may extend between the cover outer periphery and the outwardly extending grip portion of the riser section, and a mechanism removably secures the cover to the outwardly extending grip portion with the gasket therebetween, in a substantially water resistant sealing manner. The cover may alternately be cut away from the body and discarded.

Abstract: A positive displacement type pump used for applications such as pressurizing beverage dispensing containers, filling fire extinguishers, and pressuring welding tanks. CO.sub.2 or similar fluids are drawn into and discharged through the pump by a reciprocating piston driven by a rotating eccentric main bearing mounted on a bearing frame. The bearing frame comprises an open, unsealed pair of structural plates connected by tie rods, the main bearing itself being sealed by one of two seal arrangements to make it easily convertible between oil-lubricated and oil-free operation. For oil-lubricated operation, the main bearing is supplied with a surrounding sealed bearing sleeve compressed between the plates of the bearing frame. For oil-free operation, the main bearing is internally sealed. The main bearing is driven by a shaft supported on bearings in the plates, the bearings also being changeable between sealed and unsealed bearings for oil-free and oil-lubricated operations, respectively.

Abstract: A liquid level detection apparatus includes an outer tube of substantially constant diameter. A magnetostrictive wire is supported within the outer tube. An electrical circuit is mounted within the outer tube and is electrically connected to a pickup coupled to the magnetostrictive wire.

Abstract: An onboard vapor recovery system for a vehicle fuel system having a fuel tank, a filler neck dynamically sealed by high pressure fuel flow from a filler nozzle, and a vapor recovery apparatus such as a carbon canister. The system includes a liquid level operated control valve which shuts off refueling with a two-stage closing operation providing an initial soft shutoff and a final shutoff. The system also preferably includes a valve in the fuel tank to maintain a predetermined pressure head sufficient to hold the system closed against further refueling at least temporarily, and a positive action, one-way check valve in the lower end of the filler pipe to prevent spitback of fuel from the pressurized tank once refueling has ceased.

Abstract: This invention is directed to a solid electrolyte containing an alkane multifunctional acrylate polymeric matrix, a salt, a solvent, and preferably a viscosifier, as well as, electrolytic cells prepared from such solid electrolytes.

Abstract: A method of making a lithium manganese oxide intercalation compound in powder form comprises forming a solution of a manganese compound and a lithium compound in a solvent; and spray-drying the solution by atomizing the solution to form droplets thereof and contacting the droplets with a stream of non-oxidizing hot gas at a first elevated temperature to evaporate at least a major portion by weight of the solvent present in the solution thereby providing a precursor powder. The precursor powder is heated at a second elevated temperature which is below the melting point of the lithium manganese oxide compound. The second temperature is sufficient to cause reaction among constituents in the precursor powder thereby providing the lithium manganese oxide compound having a spinel unit structure.

Abstract: An anchor base for mounting machinery supports wherein fasteners extend through holes defined in the base. The base holes are provided with a concave countersunk surface which receives a complementary shaped convex fastener guide permitting the fastener to be obliquely oriented to the plane of the base, and the supporting surface and yet providing an effective holding force. This construction of the anchor base also permits an adapter to be used in conjunction with the base wherein if the supported machinery overlies the machinery support as not to provide access to the regular base mounting holes, a mechanical hold-down force on the base is still possible.

The flexible entry boot comprises a seal member disposed within the containment region; and a securing plate disposed within the containment region and releasably mounted to the seal member. A flexibly rigid, hollow support sleeve is attached to the seal member. The hollow support sleeve has a degree of flexibility sufficient to allow for the insertion of the conduit at angles equal to or other than an angle normal to the fluid containment wall while maintaining a fluid-tight environment. A mechanism is provided for releasably attaching the hollow support sleeve to the conduit.

Abstract: A stock stop for screw machines and the like for determining bar stock positioning and which is capable of sensing short stock. The stock stop includes a housing affixed to the machine tool having a slidable sleeve in which a threaded stop is adjustably positioned. A spring biases the sleeve and stop toward the advancing bar and the sleeve is displaced to a stop position by the advancing bar stock. Motion multiplying means multiply the sleeve movement upon engagement by the bar stock to actuate a proximity switch indicating proper advancement of the bar stock and permitting continued machine tool operation. As the components of the stock stop are encased and protected against contamination, a high degree of reliability is attained while providing accurate machine tool control with respect to the presence of adequate bar stock for machining.
