Patent number: 8096329Abstract: A hand-held vacuum device includes a housing to hold an electrical motor operable to drive a piston pump that is configured to draw a substantially continuous vacuum for each complete cycle of the piston pump. The hand-held vacuum device also includes an expansion chamber releasably connected to and in fluid communication with the housing and a vacuum interface that has a vacuum connector in fluid communication with the expansion chamber and is configured to releasably couple to a valve disposed on a container. The expansion chamber separates air and liquid from a fluid drawn into the expansion chamber.Type: GrantFiled: June 15, 2007Date of Patent: January 17, 2012Assignee: S. C. Johnson & Son, Inc.Inventors: Raechell M. Thuot, Bryan L. Ackerman, Brian C. Dais, Robert R. Turvey, Jeramy M. Dubay

Patent number: 7219818Abstract: A dispensing device that can economically and reliably dispenses predetermined quantity of fluids accurately comprising an elongated rod with one or more through holes formed perpendicularly through its axis defining one or more fluid flow paths. Adjacent to each through hole is an angular fluid flow path with one section generally parallel to the through hole and another section generally perpendicular to the through hole. In the preferred embodiment, the through holes and the angular fluid flow paths are positioned alternately through most of the length of the elongated rod. The elongated rod slides within a base component that has corresponding openings to enable accurate and reliable dispensing of predetermined quantity of fluids through the controlled dispensing device.Type: GrantFiled: March 15, 2005Date of Patent: May 22, 2007Inventor: Shun-I Pan

Patent number: 6726389Abstract: A paint brush assembly includes a control valve, a first rubber, a control rod, a connecting pipe, and a second rubber. Thus, the paint brush assembly has a two-stage anti-reverse effect, so that the paint contained in the container can be supplied into the barrel conveniently and can be supplied into the connecting pipe conveniently. In addition, the paint brush assembly has a two-stage anti-reverse effect, thereby preventing the paint from leaking.Type: GrantFiled: May 15, 2003Date of Patent: April 27, 2004Inventor: Kuo-Jium Lee

Patent number: 6640840Abstract: This invention relates to methods and apparatus for delivering liquid precursors to semi-conductor processing apparatus. The liquid precursor delivery system is generally indicated at (10) and includes a source (11), an inlet tube (12), a two-way valve (13), a pump assembly (14), an outlet tube (15), a shut-off valve (16) and a flash evaporator (17). The pump assembly (14) is in the form of a syringe or variable volume pump and is controlled by a combination of a step motor (27) and a linear encoder (30). The arrangement is such that unused liquid precursor can be returned to the source.Type: GrantFiled: September 21, 2000Date of Patent: November 4, 2003Assignee: Trikon Holdings LimitedInventor: John MacNeil

Patent number: 5121773Abstract: In the equipment for drawing off milk samples from a milk conveyor pipe (1), in order to remove any milk remaining from the previous supplier and adhering within the suction pipe (5) and the injection syringe (6), before taking a sample from the current supplier the suction pipe (5) and the injection syringe (6) are filled with milk and after being completely filled they are emptied again by pumping the milk back into the conveyor pipe (1). The process of filling to fullness is monitored by a control means (9) which operates a hose pump (7) such that only the exact quantity of milk required to fill the suction pipe (5) and the injection syringe (6) is conveyed. Only after this filling and emptying procedure is the injection syringe (6) inserted into a sampling bottle (8) disposed on a dish (15) which can be raised. A holding down device (16, 17, 18) guarantees perfect withdrawl of the injection syringe (6) from the sampling bottle (8) when the dish (15) is lowered at the end of the sampling.Type: GrantFiled: September 20, 1990Date of Patent: June 16, 1992Assignee: Ewison AGInventor: Heinrich Kochli
