Abstract:
PROBLEM TO BE SOLVED: To keep piston rotation prevention function.SOLUTION: A piston rotation prevention device 50 is used in gas storage equipment including a cylindrical storage part body and a piston provided in the storage part body in such a way that it can be lifted up or descended in the storage part body. The piston rotation prevention device 50 includes a protrusion 51 that protrudes inwardly from an inner surface of the storage part body and extends in a vertical direction and a pair of claw members 55 provided in the piston and arranged at both sides of the protrusion. The piston rotation prevention device 50 further includes slide members 56 which are supported at a piston side in such a way that the slide members can slide toward a diametral direction of the storage part body and which are provided in association with the respective claw members; a rotation shaft 57 crossing at a right angle with a moving direction of the slide member and provided at the piston side; levers 58 rotatably supported in respect to the rotation shaft and having abutting segments 58a arranged at the extremity end in such a way that it can be abutted against the slide member; and springs 59 which are provided near the rear end of the lever and generate a pushing pressure causing the abutting segments of the levers to be abutted against the slide members and pushing the claw members toward the protrusion.
Abstract:
The present invention provides a compressed fuel tank, comprising: an inner tank in which liquefied gas is stored; a support rod penetrating a central axis of the inner tank and having both sides of the inner tank fixed at both ends thereof; an insulating member provided to surround the inner tank so as to block heat transfer to the outside; an outer tank accommodating the inner tank, the support rod and the insulating member therein; and a rod support part fixed to both sides of the inside of the outer tank to support both ends of the support rod so as to transfer the load of the inner tank to both sides of the outer tank.
Abstract:

Abstract:
Containment systems are provided. In one example embodiment, a containment system is provided, the containment system comprising: a container; and a skeletal reinforcement comprised of flexible fibers.
Abstract:
Novel means for the inexpensive long-term storage on farms of hydrogen produced from wind power or solar energy is provided. The means allow hydrogen stored at near-ambient temperature and pressure to heat farm buildings and crop dryers many months after the hydrogen has been produced, at projected initial cost savings of 92% to 96% of the initial cost of present state of the art storage means. The novel means include inflatable and deflatable balloons protected by shields which, because they are not subjected to the stresses and loads of pressurized gas or liquid heads and because they rest on relatively cheap rural lands, are lightweight and cost-effective despite their bulk.
Abstract:
Portable cooling systems, employing a high pressure reservoir adapted to ergonomically interface with a user and/or a wearable article to deliver a flow of cooling gas through a conduit system are provided. Such a system is adapted to provide powered cooling to locations where only very small and portable cooling systems can fit. Various user retainable appliances or articles may have cooling features incorporated therein. The molded plastic high pressure reservoir may have other uses as well.
