A soldering device for radiator tanks comprises a large number of burner nozzles disposed along the entire width of and directed to the soldering area. Cooling pipes are provided on burner tables which can be adjusted so that the radiator can be inserted inside the gap formed therebetween. A control means shifts the times for starting and shutting off the supplying of an oxygen-containing gas from the burner ignition and fire extinction times.

A security system for preventing theft of the liquid contents of storage tanks, such as those used for storing crude oil. The security system includes a first selectively locked access way, a second locked access way and a discharge valve security control subassembly accessible from outside the tank only by way of both access ways when both are unlocked. The discharge valve control subassembly is operatively associated with a housed, inaccessible discharge valve which can be opened only when the...

A transportable tank for liquids is mounted in a supporting frame. The tank is covered with a detachable insulating jacket which is formed in section comprising a layer of insulating material enclosed within inner and outer skins of weather-resistant fabric. The inner skin is faced with aluminium foil to provide sacrificial cathodic protection to the tank. The sections are secured by elastic lacing which is itself protected from sunlight by flaps carried by the sections.

A ventilation device on a top wall of a fuel tank mounted on a motor vehicle includes an upper panel fixedly mounted on an inner surface of the top wall of the fuel tank and extending substantially horizontally, the upper panel having an opening vented to atmosphere. A middle panel is fixedly mounted on a lower surface of the upper panel, and a lower panel is fixedly mounted on a lower surface of the middle panel and has first and second openings communicating with an interior of the fuel tank. ...

Filling units for filling small tanks or the like with gasoline, kerosene, or other flowable materials which attach an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, removal of the displacer section from the tank, as by sliding...

A Patch for Ruptured Fluid Tanks consisting of a container having an opening a peripheral edge. A rupture in a fluid tank is enclosed within the peripheral edge of the opening. A fluid filled tubular seal is provided along the peripheral edge of the opening. The tubular seal compresses to bring the opening of the container enclosing the rupture into sealing engagement with the fluid tank. A fluid bypass passage is provided through the container. Fluids escaping through the rupture flow through t...

Concrete septic tanks have inflow and outflow orifices and near the outflow orifice have screening or baffles which are stapled or bolted to the concrete inner wall so as to force the outflowing liquids to pass a predetermined flow path with the hope to avoid solids passing out of the tank and into a draining tile bed. A novel baffle structure and device for attaching the baffles is disclosed using a linear race with forward and rearward recesses and flexible marginal flap that seals the race on...

An insulating system for storage tanks uses vertical straps and horizontal cables to form a web on the outer surface of a spherical storage tank. Fasteners and clamps positioned at intervals along the vertical straps anchor the cables in place. Panel sections are positioned transversely to the horizontal cables, the panel sections having opposing side flanges that are folded over flanges on adjoining panel sections as well as the attachment means looped around the cable.

The invention concerns a device in fuel tanks, preferably for vehicles, said tanks being provided with a mouth socket to which a filler tube is connected so as to have its one end portion projecting into the tank. Between the mouth socket and the filler tube a seal is provided, the latter being formed with a portion grippingly enclosing the mouth edge of the socket and defining, together with the filler tube, an intermediate space allowing oscillation of the filler tube relatively to the socket....

Apparatus selectively positionable in a boat for holding at least one scuba tank. The apparatus includes a receptacle, a cover covering the receptacle interior and having holes for receiving scuba tanks, and lock plates adjustably slidably mounted on side walls of the receptacle for engagement with the boat.
