A gas bottle assembly includes a container for containing a pressurized gas, and an operating head, the operating head including a valve member which in the absence of any demand for the gas, is positioned close to a valve seat such as to permit only a minimal flow of gas from the container past the valve seat, and an actuator moveable to move the valve member away from the valve seat thereby to permit a greater flow of gas past the valve seat, to an outlet for use, and wherein the actuator includes a plunger with which the valve member is integral or to which the valve member is affixed, and the actuator includes a piston part which is movable in a piston chamber in one direction in response an actuator spring acting at a first side of the piston part, to move the valve member away from the seat, and in an opposite direction in response to a combination of gas pressure and a valve return spring which is located in the piston chamber at a second opposite side of the piston part to the actuator spring.

Gas bottle assembly

A method of controlling a gas adsorption apparatus including a sieve bed containing molecular sieve bed material, the bed being cyclically operable in a charge mode to adsorb non-product gas from an air supply thereby to increase the concentration of a product gas in a product gas supply which passes to a product gas line and in a vent mode to desorb the adsorbed non-product gas which passes to a non-product gas line, and there being a passage to permit a restricted amount only of the product gas supply to pass from the product gas supply line to the bed when operating in vent mode, and wherein the method includes operating a variable flow device to permit an increased amount of the product gas supply to pass to the bed when operating in vent mode, under predetermined conditions.

Method of controlling a gas adsorption apparatus

A canister for containing a bed of particles, for example sorbent particles, which includes a loading device for applying a predetermined compressive load to the bed of particles and an adjusting device for automatically adjusting the loading device to maintain substantially the predetermined compressive load. The adjusting device functions in conjunction with the pressure of an operating fluid in the canister.
