Patent number: 7883164Abstract: A liquid storing device includes a storage unit that stores a liquid to be consumed and a rotation member inside the storage unit that rotates around a rotation axis. A blade member is installed to the rotation member to be movable in the axis direction of the rotation axis with respect to the rotation member and has a specific gravity smaller than that of the liquid. A detection member detects the blade member when the blade member is located vertically at a detection position. When the rotation member rotates in one direction, the blade member agitates the liquid while moving toward the lower side of a liquid surface of the liquid in the vertical direction along the axis direction in accordance with rotation of the rotation member. When the rotation member stops rotating, the blade member floats toward the liquid surface due to buoyancy of the liquid.Type: GrantFiled: January 28, 2009Date of Patent: February 8, 2011Assignee: Seiko Epson CorporationInventors: Hideo Noro, Toshio Kumagai

Patent number: 6120174Abstract: A method and apparatus for mixing bone cement which produces bone cement essentially free of entrained air. The apparatus includes a cartridge having two telescoping cylinders. The outer cylinder receives a cap thereon which hermetically seals the cartridge. The cap includes an outlet port in which a break-away agitator is installed and a port for connection of a vacuum pump. In use, a desired vacuum pressure is drawn on the cartridge and the inner cylinder is allowed to be drawn into the outer cylinder while the vacuum is being drawn, whereupon the inner cylinder automatically stops moving relative to the outer cylinder when the desired vacuum pressure is reached. Mixing of the bone cement is then performed under the partial vacuum thereby created. The agitator paddles provide a scraping action against both inner cylinder walls of the telescoping cylinders thereby improving mixing.Type: GrantFiled: January 14, 1999Date of Patent: September 19, 2000Assignee: Bristol-Myers SquibbInventors: Stephen H.

Patent number: 4547076Abstract: Soft-ice mixture, consisting of water or milk and commercially available powder, is frozen solid in a cylindrical container, then presented to a machine whereby the container is pressurized and which has an agitator that engages the surface of the solid to exert force along a narrow zone, whereby the material is locally melted. The momentarily melted material is immediately whipped by the agitator, before it refreezes. The agitator rotates at high speed (2,000 rpm) but advances into the material very slowly. For such action the agitator shaft is surrounded by an outer driver confined to rotation in one direction, with which the shaft has a splined connection, and the shaft in turn surrounds a threaded inner driver, with which the shaft has a threaded connection. For driving the agitator downward the inner driver is rotated in said direction, but slower than the outer driver; for driving it upward the inner driver is also rotated in said direction, but faster than the outer driver.Type: GrantFiled: March 11, 1985Date of Patent: October 15, 1985Inventor: Wilhelm Maurer
