Abstract: An integrated adsorbed gaseous fuel storage and delivery system comprising an adsorbent in a tank wherein the adsorbent has (a) an initial Working Storage capacity of at least about 140 v/v % at a storage tank pressure of 900 psig, (b) a residual loss of storage capacity that is no more than 10%, and (c) it releases adsorbed gaseous fuel via a pressure differential between the tank pressure the pressure out of the tank without the application of a vacuum to the tank or heat to the adsorbent. The system also comprises a filter capable of passing through the filter at a rate of at least 50 cubic feet of gaseous fuel per minute at 50 psi, a pressure regulator for adjusting the pressure of the filtered gaseous fuel to an operating pressure for a fuel injection system, and an electronic control module capable of operating the fuel injection system.

Abstract: A fuel extraction and pressurization system for delivering a gaseous fuel from a adsorbent fuel tank to a fuel injection system of an internal combustion engine, wherein the fuel extraction and pressurization system comprises one or more components for applying a vacuum to the interior of the tank to facilitate the extraction of the adsorbed gaseous fuel from the tank and compressing the extracted gaseous fuel to a pressure appropriate for the fuel injection system.

Abstract: An automatic switchover valve includes first and second regulator valves arranged to oppose each other axially in a single housing, and ducted in a parallel configuration within the housing. Each regulator valve includes an inlet port, a diaphragm poppet valve, and a common outlet port. Each regulator valve includes structure for adjusting the pressure setting of the diaphragm poppet valve. During operation, the poppet valve of the first regulator valve is selectively adjustable between a first setting providing a first pressure P.sub.1, and a second setting providing a second pressure P.sub.2 less than P.sub.1 by an amount equal to 2 p. The poppet valve of the second regulator valve is preset at a reference pressure P.sub.R wherein P.sub.1 >P.sub.R >P.sub.2, and P.sub.1 -p=P.sub.R =P.sub.2 +p, and wherein p is greater than or equal to the incremental pressure characteristic of the regulator poppet valves.

Abstract: A gas cabinet for enclosing one or more compressed gas cylinders is ventilated for rapid removal of any gas leaked from the cylinders. The cabinet has a perforated plate as its floor which also serves as a fresh air inlet. Since the entire floor is used as the air inlet, the airflow through the interior of the cabinet is uniform and across the full width and depth of the cabinet, virtually eliminating dead areas or channels where leaked gas could accumulate. A tapered roof provides a smooth air handling transition to an exhaust port in the roof. The exhaust port may be connected to a plant ventilation system for removing the exhausted air from the cabinet.

Abstract: A hermetically sealable fluid containment assembly is provided. Fluids, such as compressed gases, are typically stored in a base container having a shoulder with a neck projecting outwardly from the shoulder. In accordance with the invention, a collar member generally surrounds the neck and rests upon the shoulder of the base container. A locking arrangement is provided to securely fasten the collar member to the base container. A closure member in the form of a protective cap engages the collar member. To prevent the leakage of fluid between the collar and the base container, a seal is provided between respectively engaging surfaces of the base container and the collar. The leakage of gas between the collar member and the closure member is also prevented by a second seal disposed between respective engaging surfaces of the closure member and the collar member.

Abstract: A process is disclosed for use in the manufacture of multilayer thin film integrated circuits for selective removal of specific layers, and a composition of matter useful in the process for selective etching of polysilicon and silicon nitrides during the manufacture of thin film integrated circuits. A multi-layer thin film integrated circuit is exposed to a plasma formed from a gaseous mixture of nitrous oxide and a fluoro compound. The nitrous oxide preferably comprises between 2.5% and 9.0% of the mixture and the fluoro compound preferably comprises between 91.0% and 97.5% of the mixture.

Abstract: An efficient, compact boiler system providing both heating water for heating an enclosed space, such as a home, and domestic hot water for washing and similar purposes, has a limited fluid capacity primary heating coil within a combustion chamber. The coil supplies heated water to a larger capacity storage boiler located directly below the primary boiler and connected to it by header pipes which themselves form a manifold into which the primary coil is connected. The storage boiler distributes the heated water through the heating system. An elongated secondary heating coil within the boiler heats the domestic hot water supply by heat transfer from the boiler water. The return header pipe discharges heated water directly into the interior loop of the secondary coil to quickly heat the domestic hot water when the burner is "on".
