Abstract: The invention relates to a hollow fibre-reinforced plastic body comprising a curable resin-impregnated winding of high-strength fibres. To provide a strong hollow fibre-reinforced plastic body having a quick-to-make wall thickness the invention proposes that a double-walled shell which surrounds the hollow body interior is made by a first winding of one or more tapes of an uncut double pile cloth having a spaced-apart top cloth and bottom cloth and also binding pile threads which is covered by an outer winding, the windings being impregnated with a curable resin.

Abstract: A hatch in road or rail tanker (2) includes a hatch cover (7) mounted in a flange (8) of a compartment manhole (9). In order to prevent leaks from the hatch cover (7), a band (13) is welded to the top of the tank (2) around compartment manhole (9). The band (13) includes an outwardly concave flange (14) providing a groove for receiving a hatch sealing device (15). The hatch sealing device (15) includes a generally cylindrical rubber cylinder having an open end and a closed end closed by a seal membrane, also of rubber. Around the inside of the rim forming open end there is provided an internally extending lip shaped to fit into concave flange (14). Around the outside of the cylinder is provided a split ring of metal, the ends of which are drawn together in order to radially compress the cylinder and thus seal it around the flange (14).

Abstract: Method and apparatus for transporting, storing and delivering dangerous chemicals in a high pressure stacked tube array configuration. Tubes are divided into sub-groups with outside tubes containing inert gases and inside tubes containing chemicals. Inside and outside tubes in each sub-group are manifolded to permit off loading of dangerous chemicals into outside tubes in the event of a leak in an inside tube or tubes in the sub-group. The apparatus includes a manifold system for segregation of source chemicals to provide two independent outlets.

Abstract: A mobile storage tank having a jack system on the front thereof and a rear wheel lift system to facilitate the draining of fluid from the tank and the towing of an empty tank from one job site to another. Recesses are provided in the walls of the storage tank for receiving manholes, fittings and a ladder so that a maximum volumetric dimension can be obtained for the storage tank while still conforming to highway laws regulating the size of trailers. The manholes are positioned at a predetermined height above the ground to allow a person standing on the ground to have access to the interior thereof for cleaning and the like.

Abstract: A fuel fill pipe shelf for a generator set fuel tank is mounted in the upper end of a tower of the fuel tank. The fuel pipe shelf comprises an insert which is welded into an opening in the upper end of the fuel tank. The insertcupies a volume which otherwise would be part of the interior of the fuel tank. The fuel fill, vent and fuel gage are all supported on the fuel shelf. As a result, the fuel fill, fuel gage and vent are all within a protected recess in the fuel tank.

Abstract: A mounting arrangement for securing the neck of a compressed gas cylinder to a bulkhead is designed to permit articulation of the cylinder axis relative to the bulkhead without placing undue stress on the cylinder neck. The mounting includes a ball-and-socket-type arrangement in which the bail is provided by a ring formed from a sphere with a cylindricai through-passage, the ring fitting over the cylinder neck, and the socket is provided by a pair of mated flanges with flared inner edges which together contact and capture the spherical curvature of the ring. The flanges are bolted to the bulkhead. An anti-rotation plate is also mounted to the bulkhead over the protruding end of the cylinder neck, permitting the cylinder neck freedom of motion in two orthogonal directions but not rotation.

Abstract: A tank trailer assembly for transporting liquid bromine and hydrobromic acid which comprises an elongated substantially cylindrical container having three inner containers for transporting fluids. Two of the inner containers are internally lined with a poly(vinylidene fluoride) plastic material and the third container is internally lined with material that is chemically resistance to bromine.

Abstract: The present invention relates to protection against the corrosive action of hydrofluoric acid.According to the invention it has been found that a material consisting of an elastomeric substrate or matrix and a filler of metal particles dispersed in the substrate, of a metal which can be oxidized by ionized hydrofluoric acid, can limit or prevent the diffusion of hydrofluoric acid.The materials according to the invention can be employed in all the suitable forms, especially as sheets, for protecting metal walls.

Abstract: A damage-resistant containment device includes a high strength fiber covering the surface of the container and an elastomeric matrix supporting the fiber and bonding the fiber to the surface of the container. The device and method provide a damage-resistant polyolefin container which may be used to transport hazardous fluids by vehicles, such as trucks, on publicly used thoroughfares.

Abstract: A high density, substantially oxide-free metal layer is deposited by spray deposition on a substrate in an atmosphere containing ambient air having an oxygen content above about 0.1% by weight. This is accomplished by directing a supersonic-velocity jet stream of hot gases carrying metal particles at the substrate through an inert gas shroud. The layer is useful as a corrosion barrier and for repairing metal substrates.

Abstract: A fluid containment apparatus including a fluid tank, a well wall and a closure system. The tank has a tank shell, which defines at least in part a fluid containment compartment and has a tank shell opening therethrough. The well wall is secured to the tank shell, positioned at the shell opening, recessed into the fluid containment compartment and defines at least in part a recessed well. The well wall has a well wall end and a well wall end opening. The closure system selectively opens and closes the well wall end opening. The closure system includes a well head connected to the well wall generally at the well wall end, a sealing gasket, an elliptical manway cover having a plurality of drilled and tapped blind holes, a separate fastening ring having a plurality of circumferential drilled through-holes and a clamp for clamping the manway cover and the fastening ring together and sandwiching the sealing gasket on the well head.

Abstract: A fuel tank comprises a container having a chamber adapted to receive a body of liquid fuel and wall means defining said chamber, and a structure with a number of voids, said structure being so constructed and arranged within said chamber as to provide an arrangement wherein when said structure is exposed to the body of liquid fuel, said number of voids work to dissipate energy of waves created on the surface portion of the body of liquid fuel.

Abstract: An intake system comprising a conduit with a valve means which permits only passage of air in one direction overcomes liquid solidification problems associated with transporting liquid sulfur so long as the length of the conduit is sufficient that the free end within the container is below the surface of the transported liquid.

Abstract: A chamber intended for containing the effects arising from explosions, deflagrations, or detonations initiated intentionally or unintentionally inside the chamber. The chamber comprises an essentially cylindrical mantle (1) with associated sealing end pieces. Each end piece comprises an essentially flat part (2, 3) which preferably on its outside is reinforced with reinforcement members (13, 14) placed at right angles to each other. The reinforcement members are welded to each end piece and to the inner surface of the mantle, and they extend from the relevant side of each end piece in the longitudinal direction of the cylinder.

Abstract: A truck trailer useful for hauling liquid and granular material includes two liquid end chambers and one center chamber or hopper. The two liquid end chambers are frusto-conical in shape and have insulation within jacket pieces around them. The end chambers are connected by an insulated pipe extending through the center chamber.
