Abstract:
A modular energy accumulator system using compressed air. The system comprises a plurality of bladder modules disposed underwater for subjection to a hydrostatic ambient pressure. The plurality of bladder modules include a first bladder module and at least a second bladder module, each of the bladder modules being oriented substantially longitudinally about a vertical axis when made buoyant by ingress of compressed air. An interconnection pipe assembly is configured to facilitate ingress of compressed air into the bladder modules to a pressure level substantially equal to the hydrostatic ambient pressure, and also to facilitate egress of air from the bladder modules at the hydrostatic ambient pressure. The bladder modules are tethered for being maintained in the underwater disposition.
Abstract:
A method of forming an inner can of a gas cartridge including securing inner can material and pre-stressing the material such that flexion thereof during gas cartridge use is distributed.
Abstract:
A fuel cartridge, which is capable of being mounted on a tool main body of a gas-combustion type driving tool so as to supply fuel gas to a striking mechanism of the tool main body, is provided with an ejection nozzle provided at a port portion formed at an end portion of a cartridge main body and slidable with respect to the cartridge main body; a compression spring for biasing the ejection nozzle so that a tip end of the ejection nozzle protrudes from the cartridge main body; and an ejection hole formed at a side wall of a tip end portion of the ejection nozzle.
Abstract:
Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision.
Abstract:
The present invention relates to a process for the manufacture of a bladder (2) of thermoplastic polymer for leaktightness to the gases of a type IV composite tank (1) and to a type IV tank (1) capable of being obtained by this process. The process of the invention comprises a stage of polymerization of a precursor monomer of said thermoplastic polymer to give said thermoplastic polymer in a rotating mold heated to a working temperature greater than or equal to the melting point of said monomer and lower than the melting point of said polymer, so as to form said bladder (2) by polymerization of said monomer coupled to rotomolding and without melting of the thermoplastic polymer obtained.
Abstract:
Apparatus has a body with a conduit defined therein. Body is mounted between, and connected to, a charging system containing pressurized fluid and a pressurized system. One apparatus has a retractable discharge tube inserted into a first end of the body. Once the body is connected to both the charging system and the pressurized system, a force is applied on the charging system toward the pressurized system. The force causes the charging system and the pressurized system to mate with the body urging the discharge tube to retract to release fluid into the conduit, and actuates the fitting to permit the fluid in the conduit to enter the pressurized system. Another apparatus has a manually deformable charging system and an adapter with a check valve to permit manual urging of fluid in the charging system through deformation of the charging system.

Abstract:
The present invention relates to a pressurized package and a method for manufacturing and filling a pressurized package. The pressurized package has an outer container (10) and an inner container (20) situated within the outer container (10). In the outer container (10) a chamber (11) for material (12) to be dispensed is arranged and in the inner container (20) a propellant chamber (21) for propellant (20) is arranged, which are separated from each other in a manner that is impermeable to liquid and gas. The outer container (10) is closed by a cover part (15) on which a valve part (16) is arranged for dispensing the material (12) from the chamber (11) outwards. To improve pressurized packages of this type, a pressurized cartridge (30) containing a propellant (22) is arranged in the inner container (20), and the pressurized cartridge is associated with an opening mechanism (31) for at least one-time opening of the pressurized cartridge (30) to the propellant chamber (21) of the inner container (20). The opening mechanism (31) reacts to filling of the chamber (11) with material (12) to be dispensed.
Abstract:
A vessel for retaining cryogens in the form of a flexible liner for compliably retaining a cryogen and designed for controlled release of vapors generated by the cryogen. The improved flexible liner is biodegradable, with the incorporation of the biodegradable component within the resin being accomplished without adversely affecting the properties of the film at cryogenic temperatures. A preferred biodegradable film consists of a polyester comprising butane 1,4-diol and adipic acid to which a controlled quantity of terephthalic acid has been added.
