Abstract:
This invention relates to a method for the preparation and metering of substances, mixtures of substances and/or compounds in general, characterized by bacteriostatic and/or bactericidal activity, using a single pressurized container in which the substances, mixtures of substances and/or compounds in general are mixed with carbon dioxide in the form of vapour, liquid/vapour mixture or supercritical fluid for the purpose of mixing, dissolving, storing and dispensing at constant predetermined doses. The invention also relates to pressure containers suitable for dispensing the substances in accordance with the invention.
Abstract:
The invention relates to a method and a filling station for filling a motor vehicle with gaseous fuel. The fuel is compressed, stored temporarily and expanded in the fuel tank of said vehicle. The fuel has a high water content. According to the invention, oil or an oil mixture is added in a dosed manner to said fuel.
Abstract:
A pressure vessel having a relief area onto which a flange of a side port can be attached. The relief area includes a planar mating surface raised from the cylindrical sidewall of the vessel. A method for forming the pressure vessel includes providing a cylindrical mandrel provided with a side port spacer. Fiberglass is wrapped onto the mandrel and space. The fiberglass is impregnated with resin and the resin is cured. A metallic insert ring is embedded in a full bore open end of the pressure vessel. The ring has a cross-section having a height to width ratio of less than 0.7.

Abstract:
The present invention relates to a method for the manufacturing of very high pressure vessels (10) so that they survive high cycle fatigue loading. In particular, the method requires creating a residual tangential stress at a bore radius (a) of a vessel (10) such that the stress under load is more compressive than a maximum applied internal pressure (pi). Furthermore, the method may require creating a residual stress at the inner radii of the supporting jackets (30, 40, 50) such that the stress under load is compressive or zero.
Abstract:
A process is disclosed for unloading a plurality of containers (1, 2) having pressurized liquefied gas contained therein. A pressurized displacement gas (10) is fed to a first container or group of containers to discharge the liquefied gas therefrom. The displacement gas is then withdrawn from the first containers or group and is separated into a first vapor stream and a second vapor stream. The first vapor stream is heated (52) and passed to the first container or group. The second vapor stream is fed to a second container or group to discharge liquefied gas therefrom. Communication between the first container or group and the second container or group is severed and the foregoing steps are repeated for all of the containers in succession, with only the last container or group emptied of liquid remaining at the pressure of the displacement gas, and all of the containers at the end of the process except the last container or group being filled with a lower pressure vapor.
Abstract:
A container is provided for storing pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 °C (-190 °F) to about -62 °C (-80 °F). The container is constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 °C (-100 °F).
Abstract:
An opening apparatus for a gas pressure container for inflating an airbag is provided. A housing is fixedly connected to the container and communicates therewith via a discharge opening. The housing includes a principal member that has oppositely disposed open ends. A sealing element for initially sealing the discharge opening is supported by a pressure piece on a counterbearing against opening forces acting on the sealing element via gas pressure in the container. A triggering device is provided that when activated removes support for the sealing element so that the discharge opening is opened by gas pressure in the container for inflating the airbag. The triggering device is in the form of a separate unit that is independently mountable on the housing and is held n one of the end plates. Support of the sealing element is stable independently of the triggering device.
Abstract:
The invention concerns safety tanks, toric or not for motor vehicles with dual-fuel carburation LPG, to be generally located in the spare wheel housing, characterised in that their structure consists of the assembly of two shells completed or not by a central portion, 19 models as per figure 1. They are all fitted with novel single-piece multiple flanges (8 a, b, c and d), oval-shaped and comprising two orifices, one for the operating multiple valve and the other for the pressure control valve as per R 67 standards and capable of being open-air mounted for economising energy and protecting the environment.
Abstract:
An automated gas cylinder monitoring system includes: a data storage collar associated with a gas cylinder including a resident memory and an insulated housing, the insulated housing being configured for coupling with a gas cylinder; a read/write probe for writing data to and receiving data from the resident memory of said data storage collar; measuring devices for determining the volume of gas in a gas cylinder; and a host computer for transmitting information to and receiving information from the read/write probe.
