Abstract:
A pressurizable chamber device or containment vessel and method of use thereof. The device or vessel includes two chamber portions, a lid portion and a base portion, drawn to one another via a nut portion. The lid and base portions each include concave surfaces that matingly fit together, such that an internal chamber is formed when these portions are fit together. The lid and base portions each include a flange having a groove therein, such that a flexible seal element is fittable into the groove. The lid and base portions include features to matingly engage the nut portion, such that engagement thereamong draws the lid portion and the base portion toward one another, tightly sealing the formed internal chamber. A pressure, such as a resin pressure that may be precisely regulated, may then be applied, for example, to a mold contained within the formed and tightly sealed chamber.
Abstract:
Fluidtight and/or thermally insulated tank (1) comprising a bearing structure (4), a fluidtight barrier and/or a thermally insulating barrier, the said fluidtight barrier and/or the said thermally insulating barrier being of cylindrical shape and comprising a vertical wall (2) and a bottom wall (3), in which the said vertical wall has a plurality of vertical panels (8, 8′), the said bearing structure surrounding the said vertical wall, and in which the said bottom wall includes a plurality of rectangular components (5) arranged in sectors that are the image of one another but rotated, the edges of the rectangular components of one of the said sectors being respectively parallel and perpendicular to one of the said vertical panels (8), characterized in that the number of the said vertical panels is twice the number of the said sectors.
Abstract:
An apparatus for remote inspection of fire extinguishers at one or a system of fire extinguisher stations includes, e.g., at each fire extinguisher station: a detector for lack of presence of a fire extinguisher in its installed position at the fire extinguisher station; a detector for out-of-range pressure of contents of the fire extinguisher at the fire extinguisher station; a detector for an obstruction to viewing of or access to the fire extinguisher at the fire extinguisher station; and a device for transmission of inspection report information from the fire extinguisher station to a remote central station.
Abstract:
A gas storage apparatus comprises a pressure vessel in the form of a cylinder, closed by a valve, containing a non-permanent gas having under its storage conditions a gas phase and a liquid phase. A jacket formed of plastics sachets surrounds and is in heat transfer relationship with the outer surface of the cylinder. The sachets define closed compartments containing a heat release substance which is liquid at 20° C. On opening the valve, the non-permanent gas is delivered from the cylinder. The liquid phase of the non-permanent gas absorbs heat from the heat release substance which undergoes fusion. The heat release substance may be water.
Abstract:
A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.
Abstract:
A double-walled liquefied gas tank characterized in that one or more insulation spaces about the vat containing the liquid are filled with a mixture, consisting mainly of argon trapped by gravity, between the outer walls of the vat and: a) for the insulating space (2) located below the bottom wall of the vat, the base plate (3) supporting the vat; b) for the insulating spaces (5) and (6), the circular chamber (16); c) for the insulation spaces (7) and (25), the circular chamber (16) and the roof (17); d) for the insulation space (14), the suspended and sealed ceiling (12), respectively.
Abstract:
An independent vessel tank system for storing liquid gas on a vessel has a first tank member, a second, cylindrical tank member connected to the first tank member, a third tank member connected to the second tank member, wherein the first, second and third tank members provide a tank device for the liquid gas, a first supporting device provided between the third tank member and a hull of the vessel, for supporting the weight of the tank device, and a second supporting device at least partially provided along a periphery of the tank device, for supporting the tank device to the hull of the vessel. The second supporting device is flexible in a first direction parallel to the centre axis of the tank device, and flexible in a second direction perpendicular to the periphery of the tank device.

Abstract:
An aerosol container (10) dispenses a fluid product under pressure. A pressure relief mechanism (30) vents the container in a controlled manner when the container is subjected to excessive pressure so to prevent the container from bursting. The container has a container body (12) of a hollow, generally cylindrical shape. Pressurized contents of the container are expelled through a valve assembly (18) installed at one end of the container. An end piece (22) attached to the container body at the other end of the container has a first circular shaped section (26) surrounded by a ring shaped outer section (28). The pressure relief mechanism comprises U-shaped score lines (32) formed across the transition between the two sections of the end piece. These score lines create lines of weakness in the material from which the end piece is made for the end piece to fracture along the score lines when the pressure within the container exceeds a predetermined pressure level. This allows the container to vent a controlled manner rather than burst.
Abstract:
A pressure vessel is provided including an inner tank formed from a tank liner surrounded by a wound layer of composite filaments. A protective jacket is disposed on the inner tank that facilitates stacking and portability of the pressure vessel and helps to define an air passage for convective heat transfer between the hybrid tank and the environment.
