Patent number: 5234134Abstract: A dosing unit for concentrate in a post-mix beverage dispenser is described which includes an enclosed cylinder space, and a pump piston with a bore running parallel with the axis. A control piston which is in contact with the input side shutoff of the cylinder space is disposed within and movable longitudinally of the bore in the pump piston. The control piston includes an intake opening, and in contact with the pump piston, forms an outlet opening, where the intake and the outlet openings are alternately opened or closed through axial movement of the control piston with respect to the cylinder space and the pump piston. The control piston movement is restricted with respect to the accelerator piston and constrained by axial impact points, so that an axial movement forced upon the control piston causes an impulse in both directions to open or close the intake or the outlet openings, after which by carry-over of the particular impact, the pump piston is moved axially the same distance.Type: GrantFiled: November 21, 1990Date of Patent: August 10, 1993Assignees: The Coca-Cola Company, Bosch-Siemens Hausgerate GmbHInventors: Alfred Raab, Alfredo D.

Patent number: 5230447Abstract: A self-closing push-pull top for a bottle includes a threaded collar adapted to engage a threaded bottle neck. A hollow stem extends from the threaded collar and engages a cylindrical guide aperture of a cap. The cap is slidable along the hollow stem about the guide aperture to a first position in which the hollow stem and the cap are positioned with respect to one another to prevent fluid flow from the bottle. The cap is further slidable along the hollow stem about the guide aperture to a second position in which the hollow stem and the cap are positioned to allow fluid flow therethrough. A biasing member is provided for biasing the cap in the first position. Since the cap is biased in this first position, it normally remains closed. Upon application of working pressure, the biasing member deforms to allow the cap to slide to the second position in which fluid may be dispensed from the bottle.Type: GrantFiled: May 23, 1991Date of Patent: July 27, 1993Inventor: Norbert Kirk

Patent number: 5226561Abstract: A projectile for releasing a gas or other suitable fluid to initiate operation of an inflator in a motor vehicle inflatable safety system. In one embodiment, the projectile has a plurality of intersecting, concave, and inclined faces which taper to a point at the tip of the projectile. This projectile is positioned on the convex side of a dome-shaped disk which isolates the inflator from an expandable confinement. When a condition is detected requiring operation of the inflator, the projectile is freely propelled toward the disk to controllably separate the disk along lines coinciding with the edges defined by the intersecting faces of the projectile to reduce the potential for portions thereof breaking or tearing off and entering the flow from the inflator to the confinement.Type: GrantFiled: March 1, 1991Date of Patent: July 13, 1993Assignee: OEA, Inc.Inventors: Brian K.
