Abstract:
A tank jacket fits over the outside of a storage tank. The jacket includes a hole for receiving the regulator assembly. The tank jacket supports a hose support assembly for storing the supply hose and a plurality of pockets for retaining various accessories and tools. A gauge protector fits over the regulator assembly and includes a first housing section defining a first cavity for receiving the regulator and a second housing section defining a second cavity for receiving the pressure gauge. A handle is formed on the gauge protector to facilitate carrying of the tank. The gauge protector and tank jacket protect the tank and regulator assembly and provide a system for transporting the tank and related equipment.
Abstract:
A one piece, lightweight, compressed gas module (10) designed for easy loading, unloading and transport to and from automobiles, aircraft, etc. as well as easy transport across a variety of terrains including floors, asphalt, and other surfaces. The compressed gas module (10) includes a pressure vessel (14) and a frame (12) wherein the frame (12) includes a vertical member (32) and horizontal members (34, 36) extending perpendicular to the vertical member (32) at opposing ends of the vertical member. The pressure vessel (14) includes polar ends (16, 18) wherein each polar end includes a boss (20, 24) for rigidly engaging a respective horizontal member whereby the pressure vessel (14) forms a load bearing component of the module (10) in combination with the frame (12).
Abstract:
A lined composite pressure vessel (10) is adapted for mounting in upright position on a flat surface or the like in which a filament wound pressure vessel has a polar closed end (20) and is formed with a liner (15). An end boss extends through the closed end with an annular skirt positioned adjacent to an outside surface of the liner (15) in which the skirt (32) is encapsulated by the filament windings of the pressure vessel. The end boss has a generally axial portion extending from the skirt (32) forming an outwardly opening annular recess, the recess having an outer knurled surface, and receives therein winding filaments of the pressure vessel body so that the end boss is encapsulated in place. A face portion of the end boss is provided with a means by which a support platform (55) may be mounted on the end boss for supporting the torsional and bending stresses are distributed by the end boss over a substantial area of the pressure vessel.
Abstract:
A portable rack (1) for storing and transporting welding equipment such as a welding hose (2B), gages, controls (2A) and a torch (2C), is configured so that the portable rack (1) can be easily removably mounted on a standard welding gas tank (3), such as an oxygen tank. The storage rack (1) includes a vertically extending rack body (10) with a hose support member (15) on which the welding hose (2B) can be coiled for storage, a mounting member (20) extending from the top of the rack body (10), and a support yoke (30) extending from the bottom of the rack body (10). The mounting member (20) is preferably a circular ring dimensioned to fit snugly, but removably on the neck (3B) at the top of the welding gas tank (3). The support yoke (30) is preferably an arc-shaped member dimensioned to rest fittingly against the side (3A) of the welding gas tank (3). A hanger bar (40) is provided at the top of the rack body (10) to hang the gages and controls (2A) therefrom, and a hook (50) is provided at the top of the rack body (10) to hang the torch (2C) therefrom. The welding hose (2B) and other accessories may be hung on the rack (1), and then the rack (1) may be easily carried from a storage location to a welding job site, where the rack (1) may then be lifted onto the welding gas tank (3) for neatly, safely, and conveniently managing great lengths of welding hose (2B) and other welding accessories.
Abstract:
The invention relates to an acetylene capillary tube, a device which can be safely used for transferring acetylene at standard operating pressures and relies on the creation of an overload connection between two steel bottles with a U-clamp connection. Use of the invention is basically restricted to the filling of small acetylene bottles (13) involving the removal of gas from a donor bottle (12). The overload connection takes the form of one or more parallel, connecting tubes (1) as fine as a hair at each end of which is provided an end piece (2) which positively fits the steel bottle connection and is securely held by a U-clamp (3) or screw closure on the steel bottle valve. The end pieces are adapted to the respective standard connections. The capillary tube, whether connected singly or in parallel, creates a defined gas flow with its strong choke effect, preventing blowback even with incorrect use, and largely compensates for the acetone loss in the small bottle resulting from the removal of gas.
Abstract:
A tank filling system comprising a first filling coupler that couples to a first set of fittings disposed at a first tank end of a tank; a second filling coupler that couples to a second set of fittings disposed at a second tank end of the tank; a fluid source; a set of fluid lines and one or more fluid valves that communicate fluid from the fluid source to the first and second filling couplers; and a computing device configured to control the one or more fluid valves. In some examples, the tank can comprise an elongated folded tank having a plurality of elongated rigid tubing portions having a first diameter, a plurality of connector portions having a second diameter that is smaller than the first diameter and flexible corrugations and a rigid cuff, and taper portions disposed between and coupling successive tubing portions and connector portions.
Abstract:
This invention relates to a pressure vessel that is wrapped with a high-tension winding that prevents or ameliorates the effects of fatigue due to cyclic pressurizing and de-pressurizing of the vessel.
Abstract:
The present invention refers to replaceable upper or handle (2) and lower or support/base ring (4) elements for a pressurized container having an upper portion and a lower portion, wherein said upper and lower rings elements are manufactured from a thermostable material, a thermosetting material or a combination thereof, e.g. polyurethane, and comprise fastening means to releasably engage the ring elements with projections (3, 5) provided on the upper and lower portions of said pressurized container. The invention also refers to a pressurized container having said replaceable ring elements.
