    Abstract: A liquid dispensing system and a packaging apparatus which includes such a system has a chamber 6 of a chryogenic vessel 2 containing a reservoir of liquid gas 1 (such as nitrogen, oxygen or argon) which is to be dispensed in doses 26 through an outlet port 12 which is in constant communication with a sub-chamber 17. The sub-chamber 17 is part of a piston 16 and cylindr 15 device in which the piston is reciprocated by means 21 and 24 to expand and contract the sub-chamber. When the sub-chamber 17 is expanded, liquid gas enters from the reservoir 1 through flow ports 18 which are closed by the piston 16 during contraction of the sub-chamber to dispense a dose 26.Mounted beneath the outlet port 12 is a tubular skirt having internal passages 30 through which purging gas directed into the region 29 adjacent to the outlet port 12. The region 29 is purged of air to alleviate ice build-up at the outlet port 12. The purging gas liquifies at a temperature not greater than the temperature of the liquid gas at the outlet port and provides a back-pressure at the outlet port to restrain flow of liquid gas therethrough prior to the contraction of the sub-chamber 17 to dispense a dose.The doses 26 are dispensed into open topped containers that are moved successively beneath the outlet port 12 and means 50 is provided for sensing the containers and controlling the devices 21 and 24 to maintain synchronization between the dispensing and the movement of the containers.

    Abstract: The holding container comprises an inner casing and an outer casing of the same or different materials and a cryogenic liquid withdrawing pipe including an inner portion having a section advantageously in the form of adjacent spiral turns, which is kept in resilient contact, typically by means of a spring spacer against the inner face of the other casing, thus enabling to provide heat exchange contact between the section of the first part of the pipe and the outer casing notwithstanding the nature of the materials constituting the pipe and the outer casing. Application for example to self-pressurizable holding containers.

    Abstract: A ring assembly for compressed gas cylinders includes either a separate adaptor removably attachable to existing gas cylinders or, a ring member integral with the top portion of manufactured cylinders. In any case, a ring plate provides a horizontal, radially disposed lift plate that serves to allow lifting, transporting and storage of the cylinders. In the adaptor version, the ring plate surrounds a collar having upper and lower portions respectively provided with external and internal threads. The lower portion threads engage with the existing external threads on the top portion of gas cylinders and which normally provide for attachment of the required safety cap while the upper portion threads duplicate the cylinder threads and thus enable attachment of the protector cap thereto. Manipulation or hanging of a cylinder equipped with the ring adaptor may be by manual grasping of the ring plate or by insertion of lift hooks into holes formed in the ring plate or by placing lift forks beneath the plate. Such lifting means may be part of a hand operated grappling device, suspended from a hoist line, mounted upon a hand truck or the like or, fixedly attached to a wall or panel. Securing and removal of the ring adaptor from a cylinder is facilitated through use of a spanner tool having prongs engageable within diametrically opposed notches on the periphery of the ring plate.

    Abstract: A removeable protective cover for attachment to the valve and gauge assembly commonly used with portable compressed gas cylinders. The protector is easily attached to an existing valve, regulator and gauge assembly in basically two mating elements constructed for strength to absorb unexpected impact to the valve assembly. The protective cover is removeably attached to the gas cylinder and is placed adjustably into counter opposing contact with the valve assembly so that the force of any impact to the valve assembly area is transmitted through the protective cover, rather than into potentially damaging contact with the valve assembly. The mating halves of the protective cover are clamped around the threaded neck of the cylinder for basic support, constructed to totally enclose the valve assembly, and include contact between the cover and the valve assembly which may be adjusted by means of locking screws, while still exposing the reporting gauges through openings in the protective cover.

    Abstract: High pressure gas storage bottle with a single, small diameter filler neck aperture are charged with a powdered adsorbent such as activated carbon by drawing an evacuation air flow from the bottle receptacle at a point slightly below the filler neck. A charging fitting comprises a chambered body having an O-ring seal base which is clamped against the bottle nipple face by a compression nut. A length of rigid tubing having a tubular filter of pressed, microsphere tube walls at the distal or lower end thereof, descends through the body chamber and filler neck aperture. The tubular flow channel is connected to a vacuum source whereas the body chamber is connected to a powdered adsorbent supply conduit.
