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:
Process for evacuating the thermally insulating jacket (5) of a dewar (1) having an inner wall (2) and an outer wall (4), with the inner space between said walls completely or partially filled with an insulating material (9), containing also a moisture sorbing material (10) and a getter material (11), in which said moisture sorbing material is a chemical drying agent, and said getter material is a Ba-Li alloy.
Abstract:
A semi-ellipsoidal, semi-toroidal, or toroidal shell includes an annular sheet metal wall that is longitudinally segmented so as to include a plurality of annular wall segments. Each of the plurality of annular wall segments is joined to an adjacent wall segment by a respective latitudinal wall weld. Also disclosed is a tank including the shell, a vehicle including the shell, a multi-conic preform used to manufacture the shell, a method for assembling the preform, and a method for manufacturing the shell using the preform.
Abstract:
This invention relates to methods of fabricating components of a pressure vessel using a dicyclopentadiene prepolymer formulation in which the purity of the dicyclopentadiene is at least 92% wherein the formulation further comprises a reactive ethylene monomer that renders the prepolymer formulation flowable at ambient temperatures and to pressure vessels that are fabricated by said methods.
Abstract:
The present invention is directed to a protected pressure vessel comprising a one-piece electrically conductive composite boss that is isolated from contact with materials that have an electrical potential that differ from that of the conductive composite boss so as to substantially eliminate the possibility of galvanic corrosion cause by the differences in electrical potential.
Abstract:
Provided is a liquefied gas transfer device for reducing boil-off gas. The liquefied gas transfer device for reducing boil-off gas comprises: at least one transfer pipe formed in a vertical direction inside a quay for storing liquefied gas so as to transfer the liquefied gas; a branch pipe which is branched from a lower part of the transfer pipe to one side of the transfer pipe, and which has an end part opened toward a bottom surface of the quay; a valve which is connected to the branch pipe and/or the transfer pipe, and which opens and closes the branch pipe or the transfer pipe so as to move the liquefied gas from the transfer pipe to the branch pipe; and a resistance member disposed inside the branch pipe so as to interrupt the flow of the liquefied gas.
Abstract:
This invention relates to a pressure vessel having a one-piece polymeric composite with a weldable metal fitting such that the pressure vessel can be coupled to a source of compressed fluid by a welded connection.
Abstract:
This invention is directed to a polymeric pressure vessel comprising a wall prepared by living polymerization such that the wall comprises a single layer of polymer having two sub-layers, an inner sub-layer that is not a composite and an outer layer that is.
Abstract:
The present invention is directed to a pressure vessel comprising a conductive composite boss wherein the composite boss is isolated from contact with materials with different electrical potentials so as to substantially eliminate the possibility of galvanic corrosion.
Abstract:
Subject of the invention is pressure tank, especially three-bottoms tank, creating beneficially toroidal tank, comprising connected bottoms, equipped with connector pipes for installation, brackets for fastening the tank and cover, type plate, equipment equipment cover, inner bottom, inner shell, divider and is characterized by that the outer, upper bottom (1) together with outer, lower bottom (2) create outer tank shell, whereas inner bottom (4) is connected with the inner shell (3), creating the central, inner part (S) of the tank, and connector pipes (9, 9a, 9b and 14) and flow connectors (15, 15a) have on their length two zones: zone A with walls of increased thickness and zone B—with walls of reduced thickness, beneficially on the whole circumference of connector, whereas the wall thickness in zone B is between 0.5 up to 1.7 of the thickness of tank elements when the wall thickness is between 0.01 up to 2.9 mm and 0.3 up to 1.4 for walls thick above 2.90 mm.
