An improved apparatus for cleaning large tanks or vessels, such as automotive and railway tank cars. A tiltable frame having a wash nozzle assembly pivotedly mounted thereon is pivotedly mounted above a fixed support frame. The tiltable frame has, fixedly mounted thereon, an air motor which is operatively connected to a first gear box which, in turn, is operatively connected to a second gear box. The first gear box is operatively connected to the wash nozzle assembly to move said assembly back a...

An apparatus for casting toilet tanks from ceramic material in slip form is disclosed. A plurality of mold parts which include two side mold parts which when assembled define a casting cavity and a core part which is positioned in the mold cavity and is spaced from the mold surfaces of the two side parts to define the front back and side walls of the toilet tank. One of the side mold parts includes an integral base for forming the bottom wall of the tank. Each side mold part arranged in a genera...

An improved cleaning system for removing residue from the inside walls of a tank by directing a cleaning solvent flow completely over the tank inner walls at a controlled, minimum pressure. The cleaning solvent is directed through a ring assembly, which equalizes the flow of cleaning fluid through a series of equally spaced openings around the outer periphery of the ring assembly, and is supported such that the openings direct the fluid onto the uppermost surfaces of the tank interior wall. The ...

A tank installation comprising a tank having at least one flexible wall arranged to rest on a rigid apertured partition, which per se does not form part of the invention. A flexible duct is joined to said wall and is intended to pass through the aperture in the partition. One end of the duct is connected to the flexible wall of the tank by a folded-over portion located inside the tank, and the other end of the duct is arranged for connection to another device that is to be placed in communicatio...

A method of sealing leaks is disclosed comprising the use of a bituminous rubber latex emulsion. The emulsion is introduced into the passage through which a fluid is leaking by injecting, often at considerable pressures and a coagulant is used to coagulate the emulsion. Water may be used as a coagulant. Alternatively, the emulsion may be carried into the passages by the water.

An improved glass melt tank (10) having a feeder (15) and a channel (14) which interconnects the tank and the feeder and in which is arranged a rotary, raisable and lowerable regulator (20, 21) which opens and closes the channel (14) so that the feeder (15) is supplied with molten glass from the tank (10) when a level sensing means (22) senses a lower level in the feeder, the supply of molten glass being caused to cease when an upper level is sensed. The regulator (20, 21) rotates continuously i...

A leakproof soldered joint between overlying surfaces of two pieces of metal which are riveted together to bring areas of said surfaces into intimate contact with one another all around the holes through which the rivets pass, said joint being achieved by a method which, before the riveting operation, involves placement of thin washers of solder between said pieces of metal in register with aligning rivet holes therein, to establish a slight space between said pieces, and after the riveting oper...

Filling units for supplying small tanks or the like with gasoline, kerosene, or other flowable materials which attach to 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 and 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, manipulation of the displacer section, as for example by...

Apparatus for removing a liquid (2) containing suspendible solid matter from a tank (1) comprises a plurality of nozzles (47) located at the lower region of the tank. A pump (10) removes the liquid and ejects it through the nozzles (47) to cause resuspension of settled solid matter. When sufficient resuspension has occurred, the tank (1) is emptied by opening a valve to remove a portion of the liquid being transferred to the nozzles (47). The nozzles (47) are arranged as oppositely facing pairs ...

In combination, a tank and a support system located about a circular horizontal section of the tank, the support system comprising a plurality of essentially identical composite supporting units spaced around the circular horizontal section, with each said supporting unit being joined to the tank and to a base, each supporting unit having a vertical key with radial contact faces located between and in slidable contact with a pair of opposing vertical faces of a keyway, each supporting unit havin...
