Patent number: 7677412Abstract: A fluid dispensing apparatus includes a pulse generator coupled to a pump that operates in discrete cycles. Each cycle includes a first part in which fluid is drawn into the pump through an inlet, and a second part in which fluid is expelled from the pump through an outlet.

The liquid pump transports liquid from a source to the mixing chamber. The air pump propels air through the mixing chamber wherein the air becomes pressurized. The liquid and air mix within in the mixing chamber. The liquid-air mixture is propelled through the porous material by the flow of air, creating a foam that is dispensed from the outlet.Type: ApplicationFiled: August 20, 2009Publication date: March 4, 2010Inventors: Yin Man John Wong, Kwok Yung Anthony Law

Publication number: 20100025435Abstract: A grease gun used by cooperating with a rotary tool comprises a connecting rod, a transmission mechanism and a push rod. The rotary tool drives the connecting rod to rotate, and then the connecting rod rotates the transmission mechanism, so as to make the push rod extrude grease from the grease gun. Since the grease gun is used by cooperating with the rotary tool, it is unnecessary to provide a power source in the grease gun, so that the cost is reduced.Type: ApplicationFiled: July 30, 2008Publication date: February 4, 2010Inventor: Wen-I GUO

Patent number: 7651015Abstract: A concentrate/extract cartridge for a beverage dispenser for dispensing a liquid concentrate/extract and a diluent is provided. The cartridge includes a hollow body and a dispensing tube connected to the hollow body. A piston is slideably contained by the dispensing tube. The cartridge includes a valve having a valve stem that passes through a port of a valve seat connected to the dispensing tube. The port defines a flow passage through the dispensing tube. The valve stem is connected to the piston at a first end of the valve stem, and a valve body is located at a second end of the valve stem in removable contact with the valve seat for alternately opening and closing the port. A beverage dispenser having a removably insertable concentrate/extract cartridge and a method of dispensing a beverage made from concentrate/extract and a diluent are also provided.Type: GrantFiled: November 3, 2005Date of Patent: January 26, 2010Assignee: Intelligent Coffee Company, LLCInventors: Jeffrey J. Girard, Nasser Pirshafiey, Mario E. Vassaux, Heather B. Kay, Shlomo Greenwald, Zipora Greenwald

Patent number: 7648083Abstract: A dispenser adapted to be coupled to a fluid container. The dispenser comprises a dispensing head, an energy source, and a fluid pathway. The dispensing head includes a fluid pump, a motor adapted to power the pump, a trigger adapted to control the motor, and a nozzle orifice in fluid communication with a discharge end of the pump. The fluid pathway has one portion in fluid communication with an intake end of the pump and another portion inside the container. In one embodiment, the fluid pump is a peristaltic pump. The present invention may further include a valve having a membrane for controlling flow through the valve, the membrane having open and closed positions; and an element urges the membrane to the closed position, and a vacuum pressure at one end of the valve may overcome the urging of the element, thereby moving the membrane to the open position.Type: GrantFiled: August 8, 2008Date of Patent: January 19, 2010Assignee: S.C. Johnson & Son, Inc.Inventors: James Russell Hornsby, Marcellus Rambo Benson, James Augustus Keefe, III, Joseph Lee McGowan
