摘要:
A fitting with a dual locking swaging mechanism includes a projection to be inserted into the open end of an elastomeric tube. A protective sleeve is disposed over the projection. A ferrule is connected at one end thereof to a body portion of the fitting and is swaged over the tube to hold the tube onto the projection inserted into the tube. The tube is thereby held to the fitting by both frictional engagement of the tube with the projection and the ferrule and by the connection of the ferrule with the main body of the fitting.
摘要:
A wheeled personal transport device, for example, a wheelchair, includes a pressure vessel for providing a portable supply of medicinal gas for a user of the transport device. The pressure vessel is formed from a plurality of polymeric hollow chamber having either en ellipsoidal or spherical shape and interconnected by a plurality of relatively narrow conduit sections disposed between consecutive ones of the chambers. The pressure vessel includes a reinforcing filament wrapped around the interconnected chambers and interconnecting conduit sections to limit radial expansion of the chambers and conduit sections when filled with a fluid under pressure. The container system further includes a fluid transfer control system attached to the pressure vessel for controlling fluid flow into and out of the pressure vessel and a gas delivery mechanism for delivering gas from the pressure vessel to a user in a breathable manner.
摘要:
An auto-switching sub-atmospheric pressure gas delivery system (10), for dispensing gas to a gas-consuming process unit (80), e.g. a semiconductor manufacturing tool (82, 84, 86), without the occurrence of pressure spikes or flow perturbations.
摘要:
A system and method for withdrawing gas from a plurality of vessels is provided. The system is characterised by each vessel having a respective actuated valve associated with the vessel to selectively permit the withdrawal of gas from the vessel. Each vessel also has a sensing means to determine when it is substantially empty. A control means is arranged to receive a signal from a vessel when that vessel becomes substantially empty, and to close that vessel's actuated valve.

A compressed gas storage cell (30A, 30B, 30C) interconnecting manifold (41) includes a thermally activated pressure relief device (72), a manual safety shut off valve (55) and a port (74) for connecting the compressed gas storage cells (30A, 30B, 30C) to a motor vehicle power source and to a refueling adapter. The manifold (41) is mechanically and pneumatically connected to a compressed gas storage cell (30B) by a bolt (42) including a gas passage (43) therein.
摘要:
A compressed gas vehicle storage system comprised of a plurality of compressed gas pressure cells (30) supported by shock-absorbing bumpers (21, 22) positioned within a low cost, shape conforming container (11, 12). The container (11, 12) is dimensioned relative to the compressed gas pressure cells (30) whereby a radial air gap (26) surrounds each pressure cell (30). The radial air gap (26) allows pressure induced expansion of the pressure cells (30) without resulting in the application of pressure to adjacent pressure cells (30) or physical pressure to the container (11, 12). The pressure cells (30) are interconnected by a gas control assembly (40) including a thermally activated pressure relief device (74) and a conduit (63) connecting the fuel storage system to a vehicle power source and a refueling adapter. The system is attached to the vehicle with straps (14, 15) to enable the chassis to deform as intended in a high-speed collision.
摘要:
Apparatus is disclosed forming part of a liquefied gas tank, in which are integrated means to control replenishment of the contents of said tank (2, 3), means to automatically terminate replenishment flow at a designed percentage of total tank contents, means to control dispensing of the contents from said tank (4, 12, 21), means to generate an indication of the contents of said tank (13), and means to protect said tank against excessive internal pressure (20), said integrated means being all incorporated into or attached to a single, compact block (1).
摘要:
A fluid dispensing Nozzle comprising: a body (115) which is axially aligned with, and is surrounded by, a connector portion (102) for coupling and uncoupling onto a matching and mating connector receptacle (not shown) which is associated with a further fluid transport mechanism; a connection present sensor (114) which is positioned so that during the coupling process it will experience an interfering contact with the matching and mating connector receptacle; a pressure chamber (104) within which is an axially aligned pre-flow pressurised power snout (103) which is able to move along the central axis of the pressure chamber and which has a sealing portion (128) which can come into engagement with the seal or sealing section on the mating connector receptacle; a pressure chamber supply valve (107) which is located within a trigger passageway (110) between the main fluid supply and a trigger passageway valve (109) which is responsive to the positional placement of the connection present sensor. A main dispensing valve (112) for initiating or terminating the dispensing flow of fluid which can only be opened when there is static supply pressure within the pressure chamber sufficient to establish and maintain a seal between the pre-flow pressurised power snout and the sealing section on the mating connector receptacle.
摘要:
A mounting system (10), for supporting semiconductor process gas delivery and control components (26, 28, 30, 32) for assembly and use as a gas stick, aligns the connection union seals between fittings on adjacent components (26, 28, 30, 32) to absorb accumulated stresses resulting from manufacturing tolerances and reduce the likelihood of seal leakage. Components (26, 28, 30, 32) are mounted on individual upper clamp members (36) which are secured to lower clamp members (38) to form a slidable but non-rotatable radially aligned yoke around a rigid elongate support member (12) for subsequent longitudinal positioning and joining of adjacent fittings (25).
