Patent number: 6739483Abstract: A liquid dispenser has an augering screw that serves both a metering function and a valving function. The augering screw is axially movable between a position in which fluid can flow and a sealing position in which liquid flow through the nozzle is substantially prevented. The screw is preferably designed with a curved contour between the threads and with a plurality of thread-defining channels to allow liquid to fill more completely around the screw and to dispense more liquid with fewer screw turns than prior screw designs.Type: GrantFiled: February 14, 2002Date of Patent: May 25, 2004Assignee: Speedline Technologies, Inc.Inventors: Thomas J. White, William A. Cavallaro

Patent number: 6540832Abstract: A liquid dispensing system has a number of cartridges, preferably two or four, selectively coupled to a single motor with a respective clutch for dispensing dots of liquid at high speed. The motor drives a spur gear that meshes with individual spur gears associated with each of the clutches. Multiple cartridges are thus activated with a single motor and are housed together in one housing. Each cartridge is movable relative to the housing and is biased downward to a dispensing position with a spring. Air is selectively provided between the dispensers and the housing to drive the cartridges upward to a non-dispensing position. When the air is not provided, the spring returns the cartridge to its downward position. By moving the cartridge relative to the housing, the assembly can dispense at different locations without it being necessary to move the entire pump assembly every time a dot is dispensed.Type: GrantFiled: April 30, 2001Date of Patent: April 1, 2003Assignee: Speedline Technologies, Inc.Inventor: William A.

Patent number: 6299031Abstract: A pusher is disposed to drive material out of a dispensing outlet and extends into a first chamber that is configured to contain a hydraulic fluid disposed to drive the pusher. A second chamber is configured to exchange hydraulic fluid with the first chamber. A fluid control mechanism is disposed between the first chamber and the second chamber. Air under pressure is applied to urge a rapidly transforming material to flow toward one portion of a bifurcated chamber from another portion of the bifurcated chamber. The driven rapidly transforming material is allowed to drive a material from a dispensing outlet. At least a portion of the rapidly transforming material is caused to physically transform to a form that is more resistant to flowing. The dispensing outlet is caused to change position. At least a portion of the rapidly transforming material is caused to physically transform away from the form that is more resistant to flowing.Type: GrantFiled: July 28, 2000Date of Patent: October 9, 2001Assignee: The Knight Group LLCInventors: William A.

Patent number: 6082289Abstract: A liquid dispenser has a pump assembly with a housing and a cartridge that is movable relative to the housing between an upper non-dispensing position and a lower dispensing position. The movement is controlled by the selective introduction of air to create a column of air. The dispenser is otherwise biased downward. The movement of the dispenser can be used to avoid repeated upward and downward movement of a pump assembly. In a pump assembly with multiple dispensers, all but one can be raised while only the dispensing cartridge is lowered.Type: GrantFiled: August 24, 1995Date of Patent: July 4, 2000Assignee: Speedline Technologies, Inc.Inventor: William A.

Patent number: 5957343Abstract: A liquid dispensing system includes a selectively adjustable material control device and a sealing device within a dispensing device. The sealing device is in communication with a switching device to move the sealing device between a first position and a second position. The first position of the sealing device allows the material control device to draw a volume of material into the dispensing device and the second position of the sealing device allows the material control device to force the volume of material to dispense from the dispensing device.Type: GrantFiled: June 30, 1997Date of Patent: September 28, 1999Assignee: Speedline Technologies, Inc.Inventor: William Cavallaro
