Abstract: A linear motion valve is provided. The valve spool employs magnetically permeable rings, spaced apart axially, which engage a sealing assembly having magnetically permeable pole pieces in magnetic relationship with a magnet. The gap between the ring and the pole pieces is sealed with a ferrofluid. Depletion of the ferrofluid is minimized.

Abstract: A dispensing nozzle adapter for use in conjunction with nozzle down valves that are utilized in pressurized container applications. The nozzle encloses the stem and has a top portion which can be cut to create a desired nozzle opening. The bottom portion of the nozzle contains a lug which snaps over the flared section of the stem of the valve. The lug not only immovably locks the nozzle to the valve but also forms a seal with the flexible section of the valve.

Abstract: A throwaway type gas lighter is disclosed which comprises a windbreak, a fuel tank filled with a liquefied fuel gas, a spark generating mechanism including a rasp wheel and a spring-biased flint, fuel supplying means including a fuel injection pipe for supplying the fuel gas from the fuel tank, an outer valve member made of elastic resilient material and sealingly surrounding the fuel injection pipe for selectively preventing the fuel gas from flowing and allowing the same to flow therethrough when the outer valve member is suitably deformed, and fuel supply adjusting means for adjusting the fuel flow rate in the fuel injection pipe whereby when the outer valve member is actuated and the rasp wheel is rotated, the ignition is completed.

Abstract: The combination of an automated hematology analyzer (21) with an input device (20) enabling closed transfer of blood to said analyzer to a sealed specimen container having a perforable closure, and the input device itself.

Abstract: A tilting nozzle closure for a bottle includes a cap of plastics material having a side wall which has a low elastic deformability carrying an internal annular bead adjacent its open end for engagement with the neck of the bottle at least part of the end wall of the cap being more resilient than the side wall and carrying a tubular nozzle and a closure member for sealing the neck of the bottle which, in use, engages with the end of the neck of the bottle and which includes a reduced portion which in use projects into the neck of the bottle.

Abstract: The rotary drum humidifier is mounted in an opening in the horizontal supply duct of a forced warm air furnace. An annular mounting bracket surrounds the opening on the inside of the duct and has a plurality of spaced apart mounting studs extending through holes provided in the wall and surrounding the opening. The humidifier includes a housing having a bottom wall and upstanding side walls forming a water reservoir, with the side walls being provided with horizontally extending mounting flanges having apertures for receiving the studs which are then provided with nuts. A cylindrical porous drum, motor driven, is rotatably mounted in the housing and is adapted to be wetted by the water in the reservoir. Hinge means are provided along one flange of the housing through which a pair of adjacent mounting studs extend.

Abstract: A valve for an inflatable prosthesis of the type which comprises a fluid-containing envelope with an aperture closed by a valve through which a desired amount of fluid can be filled or withdrawn. The valve comprises a flat elongated conduit having a pair of sealed edges, and between said edges a pair of flat flexible wall members facing each other to form a fluid seal when they bear against one another. The conduit is open at one end. At the other end it is closed except for a slit formed in one of the walls without removal of material. The valve tends to remain closed both as a consequence of inherent closure of the slit and also as a consequence of pressure of the walls against one another.

Abstract: A tiltable discharge valve for pressurized containers especially suitable for dispensing a high viscosity product, at an unexpectedly low pressure: the valve provides for increasing flow-through cross-sectional area, as the container pressure falls; the valve includes a large disc or head secured to a tiltable stem; the container pressure presses the disc into the valve seat; the valve disc tilts around its fulcruming ring to raise its sealing ring off the valve seat; the valve seat is quite yieldable and the sealing ring sinks in deeper into the seat under higher container pressure and sinks less deeply into the seat as the container pressure decreases, whereby the extent the sealing ring rises off the seat upon tilting of the stem is container pressure determined, and the amount of product delivered to the stem outlets remains generally constant even as container pressure decreases.

Abstract: A water faucet is opened by swivelling the faucet pipe to at least one predetermined position and is closed by swivelling to any other position.

Abstract: Valve for a swiveling faucet having a valve casing, a valve disk inserted in the valve casing and an outlet tube swivelable to operate the valve disk and to thereby open and close a water passage. The valve disk comprises a unitary assembly of a first member, a second member and a soft packing interposed between the first and second members. The second member has a semicircular recessed surface and thick plate-like portions at the opposite ends of the recessed surface respectively. The valve casing is formed with vertical guide channels for guiding the thick plate-like portions of the second member.
