Patent number: 8590811Abstract: A device enables fluid pumps not specific to producing foam to be modified to be foam pumps by adding several elements to the pumps. The added elements include a supply conduit extending from an inlet of the pump to an elbow below the level of foaming liquid and hence rising above the level of the liquid to terminate in air. The supply conduit has a suction hole through which the liquid is sucked when air circulates in front of the hole. A foam discharge conduit connected to the pump outlet has a filtering grate. The foaming liquid includes water to produce foam without additional water. Additional grates and a removable extension grate are added optionally. Dimensions of the elements and dilution level of the foaming liquid are a function of the nature of the foam.Type: GrantFiled: July 25, 2006Date of Patent: November 26, 2013Inventor: Francis Poizot

Patent number: 7094135Abstract: An abrasivejet cutting head is disclosed that includes a valve assembly for preventing back-flow to the abrasive hopper of abrasive-laden fluid from the cutting head when the discharge path for the abrasivejet becomes clogged or otherwise blocked. The valve assembly is positioned within the abrasive line to conduct abrasive from the hopper towards the abrasivejet nozzle. The valve assembly further includes a discharge path which is sealed off from the abrasivejet nozzle during normal operation in response to the relatively lower pressure in the abrasive jet nozzle that results from the flowing fluid therein. If the jet path is blocked or competed in a manner that causes a backflow of the abrasive-laden slurry therein, the cessation of low pressure permits the backflowing slurry to exit via the discharge path and bypass the hopper, substantially avoiding the downtime previously required to clean the hopper.Type: GrantFiled: August 10, 2004Date of Patent: August 22, 2006Assignee: International Waterjet Parts, Inc.Inventors: Dennis Chisum, Stanley Swenson

Patent number: 6536685Abstract: A foam dispenser utilizes a deformable reservoir, a foamable fluid and air or other gas; a discharge device and an arrangement for producing foam that includes a plurality of mesh screens. When the dispenser is operated, air from inside the dispenser is mixed with the fluid to produce foam. The dispenser employs a shaped and resilient deformable seal for use in quickly recharging the container with air used in the creation of foam. The dispenser also advantageously employs an integrally molded swirl manifold to create a foam of excellent quality and consistency.Type: GrantFiled: March 16, 2001Date of Patent: March 25, 2003Assignee: Unilever Home and Personal Care USA, division of Conopco, Inc.Inventor: Robert Alfred Bennett

Patent number: 6237815Abstract: A dispensing device for pourable, especially powdery material, has a charging chute, a vertical filling pipe adjoining the lower end of the charging chute, and a closing cone arranged at the lower end of the filling pipe. The closing cone is displaceable in the longitudinal direction of the filling pipe by a shaft. The closing cone, in its open position, provides an annular gap at the lower end of the filling pipe. In its closed position, the closing cone rests against an annular face or annular edge at the lower end of the filling pipe. The closing cone, on an upwardly pointing conical face, includes blades with a desired slope. The closing cone is rotatingly drivable to convey material through the annular gap by the blades.Type: GrantFiled: June 24, 1999Date of Patent: May 29, 2001Assignee: Chronos Richardson GmbHInventor: Werner Schlösser

Patent number: 6200387Abstract: Invented is a method and system for wet processing substrates (especially for semiconductor wafers and flat panel displays) using nebulized chemicals created and carried by heated chemical gases. Different heated nebulized process chemicals are sequentially pressurized into a process chamber based on various process recipes. The micro nebulized chemicals would penetrate the intricate topologies on the substrates with heated and pressurized energy, and form a process effective thin film on each substrate. The process chamber is made of a material that is well compatible to all process chemicals and gases. It is designed to have the capability of circulating the flow of nebulized chemicals and gases to uniformly treat the inside substrates. The chamber is also designed having minimum open space to save process chemicals and deionized (DI) water.Type: GrantFiled: October 30, 1998Date of Patent: March 13, 2001Inventor: Dangsheng P. E. Ni

Patent number: 5000624Abstract: Fluidized powder in a powder preparation container is treated to impart to it a desired moisture content through the feeding into the fluidized powder of a stream of compressed air whose moisture content and temperature have been carefully regulated. Powder in the preparation container which has attained the desired moisture content is then transferred to a powder holding container and from there to a spraying device by which spraying device the powder is electrostatically charged and sprayed on articles. Further, the powder preparation container is heated along several distinct heating zones which are arranged one above the other along the axis, i.e. height, of the container. The powder in the powder preparation container is stratified with the powder at the bottom of the container being affected only negligibly by the continuous introduction of fresh powder through the top of the container.Type: GrantFiled: September 1, 1988Date of Patent: March 19, 1991Assignee: Ransburg-Gema AGInventor: Peter Steiger

Patent number: 4877158Abstract: The fluid dispensing apparatus includes a body portion supporting a pump assembly and a valve assembly. A fastening ring has an internal screw-thread for screw-threadedly engaging the neck of a container. A fastening ring retaining member allows the ring to rotate freely with respect to the body portion but also has a central opening for accommodating a fastening member which acts both to lock the member to the body portion and to couple with an outlet duct in the body portion leading to the valve assembly. In addition the member defines a separate passage which provides communication between the pump assembly and the interior of the container. The fastening member has a central opening for receiving a pipe which is arranged to extend to the bottom of the container.Type: GrantFiled: April 12, 1988Date of Patent: October 31, 1989Inventor: Tilmann L.
