Abstract:
An elastomer seal is described which is useful for forming a sealed, flat mounting surface on a curved housing. The elastomer seal has a flat sealing face opposite a curved sealing surface. An angled transition surface is adjacent to the curved sealing surface forming a bevel. The bevel assists the seal in properly deforming so that a sealing area is formed across the curved housing. This seal provides peripheral and central contact so that the distribution of compressed seal material is well spread over the surface of the sealed area. The elastomer seal is able to effectively seal housings with radii of curvature from 1 to 6.4 times the curvature radius of the curved sealing surface.
Abstract:
A trailer for cylindrical fluid containers, particularly compressed gas tubes, arranged in modules individually removable from the trailer. Each module has a front and a rear bulkhead between which tubes are supported. The tubes have reduced cylindrical ends which protrude through and are supported in openings in the bulkheads. At least one end of the tubes is threaded and clamped by a nut or a collar flange to a bulkhead. Each bulkhead has a stiffening, right-angle flange along each vertical edge which aligns with and is clamped to each adjacent module. At their bottom, the bulkheads abut and are attached to an upwardly extending side of an L-shaped structural member, the other side being mounted to the trailer frame. The tubes are arranged in line horizontally and vertically with space between them.
Abstract:
A portable air accumulator for pneumatic tools comprising a air tank which is mounted on a supporting base. The air accumulator also includes an inlet fixture for connecting the tank to an air compressor and a plurality of outlet fixtures for connecting the tank to a plurality of pneumatic tools.
Abstract:
A containment vessel system including a containment vessel into which a leaking fluid-containing cylinder may be quickly placed. The containment vessel is designed to withstand the pressure of the fluid and has closure means that may be quickly secured. Once the leaking cylinder is isolated within the containment vessel, the vessel may be relocated to facilities where the fluid can be properly disposed of. The vessel may be mounted to a carriage which may have wheels, and/or fork lift brackets, and/or lifting lugs to enhance its portability. The containment vessel may be conveniently carried on a cylinder transport truck to permit quick isolation of a leaking cylinder.
Abstract:
A swivel mount for the outlet conduit of a pressure vessel is disclosed that can be rotated to a desired position to provide access to a component attached to the mount without interrupting the flow of material from the pressure vessel to the mount and the component. The mount includes a hollow stem that is surrounded by and is in rotational sealing engagement with a sleeve. A sealed chamber is formed between the sleeve and the stem that receives material from the outlet conduit of the pressure vessel through a laterl aperture in the stem. The sleeve itself has at least one outlet conduit that is joined to the chamber and can direct material from the chamber to the component.
Abstract:
There is provided a closed storage vessel having a heat conductive mesh-like interior affixed to the shell of the tank in secure heat conductive contact.
Abstract:
An anti-rotation device having a bracket adapted for attachment to a platform and a blade projecting generally upward from the bracket for a wedge-like engagement in an opening in the neck of a cylindrical fuel tank to prevent rotation of the tank about its longitudinal axis and limit the longitudinal movement of the tank when attached to the platform.
Abstract:
A tank for the transport or storage of liquified natural gas under pressure is of generally rectangular form and has its side, top and bottom walls each composed of a series of parallel lobes of part-spherical cross-section and of say, 3.0 to 4.0 meters chord distance, each tank end consisting of either a like series of lobes or a mosaic of domes. All the inter-lobe nodes of the top wall of the tank are united to the corresponding nodes of the tank bottom by vertical tie-plates; likewise all the corresponding inter-lobe nodes of the two side walls are united by transverse tie-plates which intersect the vertical tie-plates orthogonally, and thereby define with them a plurality of tunnels of square cross-section.The tie-plates extend longitudinally to unite the end walls of the tank and are welded to one another at all tie-plates inter-sections. The tank is supported on a series of parallel support ribs or frames that connect with the tank along the inter-lobe nodes of the tank bottom.
Abstract:
A pressure release valve is located in the domed bottom of an aerosol can. A centrally located area in the domed bottom having a lesser resistance to eversion than the peripheral area in the domed bottom includes several score lines which meet at a common point in a spoke-like configuration. The centrally located area of the bottom will evert at a pressure of 170 to 200 p.s.i. so as to rupture the bottom at the source lines before any substantial eversion of the peripheral area occurs.
