The frame (2) comprises lateral sprayers (5) for spraying water to the sides of the vehicle (3) and overhead sprayers for spraying water to the upper part of the vehicle (3). The overhead sprayers (8) are divided into at least two groups such that the overhead sprayers in one group swing synchronously with the overhead sprayers in the other group to the opposite direction transversely to the vehicle (3) to be cleaned. The forces generated by the water jets from the sprayers (8) thus compensate for each other, whereby the vehicle washing apparatus (1) does not swing in the lateral direction.Type: GrantFiled: April 19, 1996Date of Patent: March 10, 1998Assignee: Tammermatic Ltd.Inventor: Seppo Jaakkonen

Patent number: 5680990Abstract: A rotary head structure of a lawn sprinkling seat, including a base seat, a sprinkling head and a T-shaped locking body. The base seat is formed with a central water-outgoing connector. The sprinkling head has three radially extending water-outgoing passages spaced by equal angle and an insertion post on bottom face for fitting into the locking body which is screwed into the water-outgoing connector of the base seat. The water is conducted from the base seat to the sprinkling head to flow out from the water-outgoing passages thereof. A free end of each water-outgoing passage is formed with a large diameter hole having a conic peripheral wall for receiving a valve post of a hollow ball valve. The valve post of the ball valve is first passed through a tapered opening of a cylindrical valve sleeve and then fitted into the large diameter hole of the water-outgoing passage and fused therewith by ultrasonic wave.Type: GrantFiled: December 27, 1995Date of Patent: October 28, 1997Assignee: Yuan Mei CorporationInventor: King-Yuan Wang

Patent number: 5673716Abstract: The invention relates to a device for sealing the transitional region between a rotatably mounted spraying arm of a dishwashing machine and its stationary bearing member by means of a sealing element, which is disposed therebetween and is impinged by the rinsing water flowing therethrough. The sealing and sliding friction functions are separated through the inclusion of a slip ring in the transitional region and this achieves significant sealing with a long service life.Type: GrantFiled: October 25, 1995Date of Patent: October 7, 1997Assignee: Whirlpool Europe B.V.Inventors: Vincent Paulraj Gurubatham, Bernhard Mohrbacher, Ludwin Rauber, Gerd Kloss

Patent number: 5662270Abstract: A straight line motion producing apparatus useable in the papermaking process includes a base, a first arm rotatable about a first axis being stationary relative to the base during rotation of the first arm. A second arm is rotatable about a second axis extending through the first arm such that the distance between the first axis and second axis remains constant. The second arm should be of a length relative to the distance between the first and second axis to produce a straight line motion at a particular location of the second arm upon rotation of the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis. The apparatus further includes a mechanism for rotating the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis to produce a straight line motion at a particular location on the second arm.Type: GrantFiled: June 29, 1994Date of Patent: September 2, 1997Inventor: Robert V. Scarano

Patent number: 5660633Abstract: A powder supplying apparatus supplies, for example, a powder spraying apparatus with fine powder particles such as of ceramics having particle sizes of several .mu.m to 10 .mu.m at an extremely small rate of several grams to several tens of grams per hour, in the form of micronized discrete particles dispersed at a high degree of uniformity. The powder spraying apparatus is capable of spraying the fine powder particles on an object surface with a high degree of uniformity of distribution. The disclosed apparatus is used typically in uniformly spraying the above-mentioned fine powder particles which serve as spacers between a pair of transparent substrates of a liquid crystal display panel, for the purpose of maintaining a uniform and constant gap to be filled with a liquid crystal between these transparent substrates.Type: GrantFiled: August 17, 1995Date of Patent: August 26, 1997Assignees: Nisshin Flour Milling Co., Ltd., Nisshin Engineering Co., Ltd.Inventors: Hiroshi Murata, Kimio Miyagawa, Eiji Shinoda, Hideo Moriyama

Patent number: 5657782Abstract: A header, a rotating head and a base piece are sequentially mounted on the end of a stand pipe. Water hoses attach to threaded connections in the header. Channels in the header and rotating head supply water from the water hoses to number of passages, that in turn carry water to a number of nozzles located along an outer face of the rotating head. The nozzles are pointed so as to create water jets, which break up material on the floor of a septic tank and generate a torque in the rotating head that turns it about the stand pipe. Spring-loaded legs on the base fold up to allow the apparatus to be inserted through an opening in the septic tank, then extend outward to provide a stable stand. An extension fits over the opening in the septic tank and effectively raises the opening of the septic tank to ground level. A cap covers the extension when not in use.Type: GrantFiled: January 5, 1996Date of Patent: August 19, 1997Inventor: Robert D. Berning

Patent number: 5615696Abstract: The disclosed apparatus and method relate to a cleaning nozzle which, in multiple embodiments, is rotated in a circle or in an ellipse, being one nozzle in one embodiment and multiple nozzles in alternate embodiments so that the surface of a pipeline can be clean with high pressure water or other fluids. Furthermore, the rotating nozzle is supported in a carriage in one embodiment which encircles and travels along a pipeline. The carriage is supported by drive wheels which cooperate with separate drive motors and a control circuit to assure that the carriage remains upright. Multiple rotating nozzles are supported in the carriage to clean adjacent portions of the pipeline. Alternate embodiments are shown for cleaning a horizontal surface with a hand pushed or motorized version, and another version is disclosed supported on a moveable boom, thereby enabling cleaning of an upstanding vertical surface such as the hull of a ship.Type: GrantFiled: August 16, 1993Date of Patent: April 1, 1997Inventor: Oliver W. Lawler
