Patent number: 5174163Abstract: A gas sampling apparatus including a flexible, substantially gas-impervious, closed bag and a valve assembly mounted in a wall of the bag for providing control of gas flow between the interior and exterior of the bag. The valve assembly includes a valve body mounted in the bag wall for providing a first gas conduit to and from said interior of the bag, and a valve stem for providing a second gas conduit, the stem terminating at one end in a ball mounted on the valve body. The stem is movable about the ball between an opened position in which the gas conduits are in communication with one another and the bag may be filled or emptied through the coupled conduits, and a closed position in which the ball seals the first conduit. A valve cap is provided for capturing the stem at variable pressures between the valve body and the cap. The cap has a slot in one side in which the stem is movable tranversely to its long axis between its opened and closed positions.Type: GrantFiled: January 18, 1991Date of Patent: December 29, 1992Assignee: BGI IncorporatedInventors: Robert A. Gussman, Gertrude A. Gussman, Kevin E. DeVoe

Patent number: 5135140Abstract: A sealable and dispensing pouring spout is disclosed. A collar member is mounted on a tubular body member, these two parts defining a cam follower surface therebetween. The tubular body member has a stopper attached at an open end thereof. A spout shaped member is rotatably mounted on the tubular body member and has a cam follower which engages the cam follower surface. The spout shaped member can be rotated on the tubular body member into engagement with the stopper member to close the pouring spout or to other positions to open the pouring spout.Type: GrantFiled: August 7, 1991Date of Patent: August 4, 1992Inventors: Paul R. Maguire, John M. Lown

Patent number: 5129584Abstract: An adjustable valve nozzle assembly is provided wherein a partially circular male body is disposed in a socket of a female body so that conduits in each of the bodies may be in fluid communication. A nozzle is mounted in the male body, with the fluid inlet being in the female body. A gasket is provided in the female body for sealing between the socket and the partially circular male body. The socket has an adjustment opening larger than and receiving an extending neck on the male body for permitting angular adjustment of the nozzle in all directions, and a slot extends along a diametral plane from the opening in the socket to form a keyhole-shaped slotted aperture to receive the neck and for permitting the nozzle to be rotated at least about 45 degrees relative to the female body for a shut-off or trickle-flow condition of the valve nozzle assembly.Type: GrantFiled: November 13, 1990Date of Patent: July 14, 1992Inventor: Ralph G. Ridenour

Patent number: 5110086Abstract: An improved irrigation valve has a valve housing with a tubular passage and an inlet opening in one side. The valve housing can be attached to an opening in an irrigation pipe so that water from the pipe can flow into the housing and through the inlet opening. A tubular valve in the tubular passage has a flow opening in its wall and an open outlet end, the valve member being rotatable in the passage to align the flow opening with the inlet opening to different degrees to control the flow of water through the valve from the pipe to the outlet. A baffle extends along an inside wall of the valve member to interfere with circular flow of water within said valve member to thereby reduce a fan effect at the outlet which such circular flow causes, the fan being a cause of erosion of the irrigated soil. Annular and axial ribs between the valve member and tubular passage reduce the ingress of dirt to reduce maintenance of the valve.Type: GrantFiled: April 30, 1991Date of Patent: May 5, 1992Assignee: Aqua Control, Inc.Inventor: Guy A.

Patent number: 5045068Abstract: A flow rate regulator includes a first cylindrical member, a second cylindrical member and a disc-shaped member to regulate, the flow rate of liquid flowing through a transfusion unit. The liquid is introduced into the second cylindrical member via an inlet port. It flows through the disc-shaped member via a through hole and flows further along a peripherally extending groove in the first cylindrical member. Then, it is discharged from the first cylindrical member via an outlet port after the flow rate is regulated as required. The disc-shaped member is fitted in the second cylindrical member so as not to be rotated relative to the latter, and the sub-assembly is then fitted into the first cylindrical member. The peripherally extending groove is so designed that its cross-sectional area is gradually varied on the bottom portion of the first cylindrical member. The through hole in the disc-shaped member is communicated with the peripherally extending groove.Type: GrantFiled: April 10, 1989Date of Patent: September 3, 1991Assignee: Japan Medical Supply Company LimitedInventors: Tatsuya Kawai, Takashi Matsuda

Patent number: 5014964Abstract: An adjustable vent nozzle has two nozzle members turnable relative to one another, the first nozzle member having an inlet opening for communicating an interior of the nozzle with ambient atmosphere and a lower surface provided with a guiding, the second nozzle member having an outlet opening with a passage which is open in the outlet and formed to guide the guide of the first nozzle member so that in an assembled condition when one of the nozzle members is turned relative to another of the nozzle members the guide is guided in the air passage. In a predetermined angular position of the nozzle members relative to one another they can be fixed relative to one another to define a predetermined length of the passage between the inlet opening and the outlet opening and therefore to adjust an air supply through the nozzle into an interior of a device to be vented and communicating with the outlet opening.Type: GrantFiled: February 9, 1990Date of Patent: May 14, 1991Assignee: K.
