    Abstract: Portable emergency breathing apparatus is disclosed which is comprised of a compressed breathing gas container having a housing mounted on the open end thereof which supports a pressure gauge, a pressure reducing valve assembly, and burst valve, fill valve and needle valve components. The pressure reducing valve controls the flow of breathing gas from the container to a breathing hose attached to the housing and leading to a face mask or hood worn by the user. The housing has a flat axially outer end relative to the container and a radially outer periphery which is within the cylindrical plane of the side wall of the container, and the housing is structured for mounting on the container so as to optimize compactness of the apparatus and protection of the pressure gauge and the pressure reducing, burst, fill and needle valves from damage during storage and use. A modification of the housing enables the apparatus to include two or more compressed breathing gas containers in side-by-side relationship, thus to increase the duration of use of the apparatus.

    Abstract: A controlled stream of liquid cryogen is delivered from a system comprising: (a) a source of liquid cryogen at a substantially constant pressure, remote from the outlet; (b) a conduit connecting the liquid cryogen source to the outlet; (c) means to maintain cryogen flowing through the conduit sub-cooled at all points along the conduit (i.e., at any given point in the conduit, the cryogen's equilibrium vapor pressure is below the pressure experienced at that point in the conduit), and to deliver the cryogen to the outlet at a temperature equal to or below its boiling point at atmospheric pressure; and (d) a flow-rate control restriction, positioned in the conduit. By maintaining the cryogen sub-cooled, the flow is kept substantially (at least about 95% by volume) liquid. Therefore, the flow in the conduit is controlled reliably as to pressure, flow rate, and size. Specifically, the rate at which liquid cryogen is delivered at the outlet is controlled by the cross-sectional area of the flow-control restriction, and severe flashing at the outlet is avoided.

    Abstract: A safety relief valve for liquified gas containers has dual pilot valves, one set to a given operating pressure and one adjustable. A main valve is responsive to the pilots, which are connected in parallel. The adjustable pilot is continuously adjustable and may be set below the operating pressure of the set pilot. The main valve has an inlet at the tank wall and a valve seat with a lateral outlet downstream thereof. The piston is faced at the inlet side by the gas pressure in the tank and on the control-pressure space side with a closing pressure adjusted by the pilots. If a given pressure in the tank is exceeded, the piston lifts from its valve seat, so that gas can flow from the inlet to the outlet. The second pilot valve can be provided with a thermal or other enabling means to initiate its operation when desired.

    Abstract: A charging fixture for gas charging a damper includes a pair of body members adapted to be forced together under pressure. Alignment pins align the body members as they are forced together. Compressable elastomeric members define a cavity in the body members and are disposed in the body members and sized for compressing and deforming portions of an outer cylinder surface of the damper during charging. A passageway to the cavity is connected to a high pressure source of gas, and the damper is charged by gas entering from the cavity by displacement of a piston rod seal from along an intermediate cylinder head.

    Abstract: A pallet for handling and transporting a plurality of pressurized gas cylinders includes a floor structure on which the cylinders stand and side walls to retain the cylinders in place on the floor structure. For certain gas delivery applications it is desired to gang the cylinders by connecting them to a common manifold which is protectively supported on the pallet. To this end, a pair of upright center posts are provided at opposite sides of the pallet. The posts extend above the tops of the cylinders. A cross bar interconnects the upper ends of the posts and provides a structure for protectively supporting a manifold. An elongate manifold depends from and is supported by the cross bar. The manifold has ports which are connected by flexible high pressure hoses to each of the cylinders. The cross bar preferably takes the form of a truss structure which additionally cooperates with the center posts to provide a lifting frame that can be engaged by a crane for handling the pallet.
