Patent number: 5056716Abstract: A washer is described for cleaning the interiors of tanks that hold milk, beer, chemicals and so on. A body 2 reciprocates relative to a substantially surrounded and relatively fixed piston 19. The body 2 oscillatably supports three nozzles 7 each of which is movable through an arc of 60.degree. and which arc is angularly spaced from those corresponding to the other two nozzles 7 by further angles of 60.degree.. However, the body 2 and nozzles 7 are also indexed, during operation, in steps, around a further axis which is perpendicular to, and offset from the axis of oscillation and which substantially corresponds to the longitudinal axis of the tank washer itself. Thus, each nozzle 7 cleans not only an arc of 60.degree. but rotates that arc through 360.degree. so that the whole of the interior of a tank is both washed and substantially rinsed by the three nozzles 7.Type: GrantFiled: February 20, 1990Date of Patent: October 15, 1991Assignee: Breconcherry LimitedInventor: Michael Robinson

Patent number: 4251063Abstract: Disclosed is a device for guniting the lining of casting ladles, comprising a platform which is mounted by means of adjustable supports on the ladle to be repaired. On the under side of the platform a guide is mounted so as to extend downward from the platform into the casting ladle. A carriage with a nozzle for supplying gunite onto the surface being repaired is mounted for reciprocating motion along the guide. The guide is fitted on sleds which, in turn, are set on a swivel table so as to permit radial displacement of the sleds relative to the axis of rotation of the swivel table, the swivel table being rotatably mounted on the platform. On the under side of the platform there is also arranged a detachable templet whose curvature is similar to the curvature of the horizontal cross-section of the ladle. A roller pair is mounted on the templet to run around it.Type: GrantFiled: July 30, 1979Date of Patent: February 17, 1981Inventors: Ilya A. Goldberg, Boris A. Kobtsev, Jury A. Polonsky, Boris A.

Patent number: 4244523Abstract: 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 and forth along the longitudinal axis of the tank or vessel to be cleaned. The second gear box is operatively connected to the fixed support frame to tilt the tiltable frame and thereby move the wash nozzle in both directions along the latitudinal axis of the tank or vessel to be cleaned.Type: GrantFiled: March 15, 1979Date of Patent: January 13, 1981Inventor: Bruce T. Looper

Patent number: 4225083Abstract: Refractory material in wet slurry form is applied onto the inner surface of a furnace. The improvement is characterized in that the water to be added into the powder-like refractory material for producing the above slurry refractory material is finely and accurately regulated so that the resultant refractory material sprayed from the spray nozzle fixedly adheres onto the abraded or eroded portion of the inner surface of the furnace with a minimum amount of rebound loss.Type: GrantFiled: June 5, 1978Date of Patent: September 30, 1980Assignee: Kurosaki Refractories Co., Ltd.Inventors: Sueki Kubo, Toshiro Watanabe, Masayuki Fujita, Tadahiko Matsuno, Akira Morita

Patent number: 4214705Abstract: An apparatus for cleaning tanks which is inserted into an opening at the top of the tank to be cleaned. The apparatus has an elongated cylindrical housing with an upper fluid inlet portion and a lower portion having a cylindrical rotary member coupled for rotation to the housing. The apparatus includes an air motor in the upper portion. In the lower portion, the main component is a high pressure block with an elongated axial aperture and a plurality of feed tubes disposed parallel to the axial aperture are held by the block. There is a central rotating vertical main tube in the central aperture which carries high pressure liquid. At the end of the high pressure block is a bevel housing gear and a nozzle tube is coupled at right angles to the central vertical tube. This nozzle tube has vertically disposed spray nozzles at one end and a bevel gear at the other end which is engaged with the bevel housing gear.Type: GrantFiled: December 18, 1978Date of Patent: July 29, 1980Assignee: Chemdet Sonic Systems, Inc.Inventors: Grady Watts, Michael Robinson

Patent number: 4211367Abstract: A housing having an interior chamber with an inlet and outlet thereto is suspended by a crane within a ladle or furnace having an interior refractory surface to be relined. A feed conduit for conveying dry refractory material entrained in an air stream extends through the inlet into the interior chamber. A nozzle assembly having a pair of oppositely positioned spray nozzles is rotatably supported in the outlet of the housing. A conduit of the nozzle assembly is rotatably connected at one end by a coupling to the feed conduit within the housing and communicates with the spray nozzles. Each of the spray nozzles includes a water ring that receives a wetting agent, such as water, from a supply conduit that is connected by a swivel assembly to the nozzles to permit rotation of the nozzles relative to the supply conduit. Each water ring directs the water into mixture with the air entrained dry refractory material flowing through the nozzle.Type: GrantFiled: August 16, 1978Date of Patent: July 8, 1980Assignee: BMI, Inc.Inventor: Ralph E.
