A protective cover for medical gas canisters includes a membrane that serves as a physical barrier to cross-contamination of biohazards in healthcare settings. An opening allows for insertion of the canister, and perforated access points that are permeable to gas provide access to valves. Sterilizing material in the access points help disinfect valves. The top of includes slack so that the membrane does not tear when handles and knobs are grasped and manipulated. A visual alignment marker indicates proper rotational alignment of the perforated access point with valves. The membrane is see-through so labels and gauges remain viewable. Elastic bands help provide a tight fit about the canister. A user slips the membrane over a canister, rotationally aligning the visual alignment marker with a valve, and connects a hose to a valve through the access point such that the perforated access point forms a seal over the valve.

A portable gas cylinder assembly is provided that includes a gas cylinder having a central axis and a protective shroud configured to encase the gas cylinder and including first and second opposed half-sections mechanically connected to one other along a vertical plane intersecting the central axis of the gas cylinder.

A high-pressure gas tank connection structure including: a tank main body; a tank side connector; a connection side connector; and a valve body, the valve body being provided further toward a deep side along the axial direction of the tank main body than the tank side connector, the valve body being urged toward the connection side connector, and, in a case in which the valve body is pushed by a distal end of the convex portion in a state in which the convex portion is joined with the concave portion, the valve body being opened from a closed state, and communicating the interior of the tank main body with the exterior to the tank main body.

A fuel transfer station may provide for the refilling of fuel canisters providing fuel to combustion powered equipment. The fuel transfer station may include a base, a frame coupled to the base, a first connection port and a second connection port provided in the base, and fluid flow lines connecting the first connection port and the second connection port. A supply tank may be supported by the frame and detachably connected to the first connection port. A fuel canister to be refilled may be detachably connected to the second connection port. Fuel contained in the supply tank may be selectively supplied to the fuel canister through the fluid flow lines in response to a pressure gradient drawing the fuel into the fuel canister.

The present invention is directed to a new concept for a large-scale high-pressure Honeycomb Set Tank in an ISO container and for its manufacturing facilities. A process for manufacturing a plurality of honeycomb cells with a high degree of accuracy is also provided.

A high pressure tank includes: a container body including dome parts; a reinforcement layer provided on an outer surface of the container body and including fiber-reinforced resin; and a protective member provided on an outer surface of the reinforcement layer, wherein the protective member includes a first layer disposed at the outer surface of the reinforcement layer that covers at least a part of the dome parts, and a second layer disposed outward of the first layer. The first layer is more deformable due to the same load applied from the outside than the second layer is.

An in-stock compressed gas delivery assembly to deliver gas to an airsoft gun, including a cartridge receiving portion to receive at least a portion of a compressed fluid cartridge, a locking cap to secure the compressed fluid cartridge in the gas delivery assembly, a puncture pin assembly to puncture a nozzle of the compressed fluid cartridge when the locking cap is closed over the cartridge, a regulator to regulate a volume of gas passing from the gas delivery assembly, and a plurality of expansion chambers configured to form a tortuous path, between the cartridge and the regulator, to expand liquid from the compressed fluid cartridge to gas, and a buffer tube having a first end configured to be coupled to the airsoft gun; and a second end configured to receive the gas delivery assembly such that the buffer tube houses at least a portion of the gas delivery assembly.

A device is provided for protecting a high-pressure gas tank in a motor vehicle The device has an intumescent layer which is arranged and designed such that the intumescent layer at least partially shields the high-pressure gas tank. The intumescent layer includes an intumescent metal material.
