Abstract:
A process of constructing a large diameter tank is provided. The process includes the step of providing a tank wall mandrel that has at least one drive wheel and at least one curved panel. Glass fibers are applied from a vertical winder to the curved panel in order to form a segment of a tank wall shell. Additional glass fibers are also applied to the curved panel at a location above the segment of the tank wall shell in order to form a unitary tank shell.
Abstract:
A gas cylinder, such as a scuba tank, is formed with raised ribs that extend longitudinally from near the top of the cylinder to near the bottom of the cylinder. The longitudinal ribs may be arcuate and equally spaced along the outside circumference of the cylinder so as to protect the body of the cylinder from damage. The gas cylinder may be made from steel or an aluminum alloy, such that the longitudinal ribs are formed by backward impact extrusion. The gas cylinder may be configured with a cylindrical neck at the top of the body so as to house a valve and valve stem. The gas cylinder may be transported using a wheeled pedestal having an adjustable strap for securing the cylinder to the pedestal. A valve protector with an optional handle and retaining clip is provided.
Abstract:
A gas pressure regulator is provided that includes a body defining a front portion and opposed side portions. A first gas pressure indicator is mounted to a lower end of the front portion of the body, and a second gas pressure indicator mounted to an upper end of the front portion of the body, wherein the first gas pressure indicator and the second gas pressure indicator are stacked in a vertical configuration. Additionally, a pressure adjustment knob is mounted to one of the side portions of the body in one form of the present disclosure.
Abstract:
A mounting bracket assembly includes a clamping arrangement mounted for vertical movement on a mounting structure and is movable between an engaged position and disengaged position relative to a self-contained breathing apparatus held in the mounting bracket assembly. A camming arrangement is located between the clamping arrangement and the mounting structure for permitting and preventing vertical movement of the clamping arrangement relative to the mounting structure. A powered latching mechanism is engageable with a portion of the clamping arrangement for providing unlatched and latched positions. A control arrangement separate from the powered latching mechanism is operatively connected thereto to selectively control the powered latching mechanism and effect release of the self-contained breathing apparatus from the latched position when the vehicle is in a stationary and parked condition.
Abstract:
Vessel comprising a number of composite storage tanks for transport of compressed natural gas (CNG) or a combination of gas and liquid, which tanks have an elongated, cylindrical intermediate section and a lower end and an upper end, the tanks being arranged side-by-side vertically standing in the vessel, distinguished in that the hull, the bulkheads and the deck of the vessel form a closed space enveloping all tanks except from the upper end of each tank or selected tanks, for which tanks the upper end extends sealingly out of the closed space, all feed-throughs in the tanks with couplings for loading and unloading are outside of the closed space, at the upper end of the tanks, and the tanks are supported such that each tank can expand or contract freely within the operating range of the tanks with respect to pressure and temperature.
Abstract:
A tank for storing gas is provided with a dye capsule layer including capsules containing dye or with an impact recording layer formed on the outer surface of the tank body. The impact recording layer has, for example, a hear-insulating material layer formed on the outer surface of the tank body, having a heat-insulating function, and capable of holding deformation, a dye capsule layer formed on the outer surface of the heat-insulating layer and including capsules containing dye, and a dye absorbing layer formed on the outer surface of the dye capsule layer and capable of absorbing dye. By an impact, the dye released from the dye capsule layer is absorbed into a dye absorbing layer of the tank. The dye exudes on the surface of the dye absorbing layer and spreads. The degree of impact given to the tank is estimated from the degree of spread of the dye or the degree of density of the dye.
Abstract:
A compressed gas cylinder hanger having resiliently flexible engagement with the neck of the compressed gas cylinder to fix or resist rotation of the compressed gas cylinder hanger about neck.
Abstract:
A vertical fuel tank support system for efficiently supporting a vertical propane tank above the ground. The vertical fuel tank support system generally includes a support pad including an internal cavity, wherein the internal cavity extends throughout the support pad, an inner platform defining a first portion of an upper surface of the elongated support pad, wherein the inner platform is comprised of circular configuration, an outer platform defining a second portion of an upper surface of the elongated support pad, wherein the outer platform is comprised of circular configuration and an internal ribbing structure extending within the internal cavity and beneath the inner platform and the outer platform. The internal ribbing structure includes a first ribbing portion and a second ribbing portion, wherein the first ribbing portion interconnects with the second ribbing portion. The first ribbing portion extends across the inner platform and the outer platform and wherein the second ribbing portion extends solely around the outer platform.
Abstract:
The present invention provides a handle or shroud for carrying or manipulating portable gas cylinders and gas cylinder valves for the administration of medical gases, such as oxygen. The shroud of the present invention provides improved safety and versatility to the handling process of such cylinders and valves. In one embodiment, the handle or shroud allows an individual to lift the cylinder, valve and shroud from about 26″ off the ground or floor with the wrist turned up.
Abstract:
A cylindrical structure includes a vertical wall (3) and a bottom wall (2), the bottom wall having a plurality of sectors (4) which are rotated images of each other, each sector including a plurality of adjacent rectangular elements (8), characterized by the fact that the bottom wall has the shape of a regular polygon whereof each side (6) corresponds to one of the sectors, the edges of the rectangular elements of one sector being respectively perpendicular and parallel to the side of the polygon corresponding to the sector.
