Patent number: 9417145Abstract: A technique to assess or analyze cap removal or opening torque or rotational position is provided. In at least one form, a high speed, on-line machine vision system measures or determines the rotational position of a cap on a bottle, measures or determines the rotational position of the finish or neck of the same bottle, and then optionally uses such positional information to predict the opening or removal torque that will be required for a consumer to remove the bottle cap from the bottle.Type: GrantFiled: April 22, 2014Date of Patent: August 16, 2016Assignee: Pressco Technology Inc.Inventors: Don W. Cochran, Thomas P. O'Brien, Thomas Henry Palombo, John A. Seifert

Publication number: 20150209741Abstract: A polymer mixer comprising an impeller formed from a series of rotating discs mounted to a drive shaft and driven by an electric motor. Polymer is piped through a mixing chamber to the inlet of the rotating discs that creates a high shear mixing zone. Dilution water is also piped to the high shear mixing zone which is a concentric hole in the center of the discs which serves as a liquid inlet when the discs are spinning. The discs are in close proximity creating high velocity and turbulence via centrifugal force. An open design between the discs allows the disc surface to pass the solution molecules multiple times before the molecules exit the perimeter, creating a shearing affect by the high speed surface in the solution. Discs of smaller diameter are coupled to the high shear discs to further mix and recirculate more viscous solutions.Type: ApplicationFiled: January 27, 2015Publication date: July 30, 2015Inventors: Ralph Leavelle Morrison, Glen John Seifert, John M. Strack, Edward J. Thomas

Publication number: 20090243281Abstract: A connector includes gripping features. The gripping features can comprise two surfaces that generally oppose each another. Each surface can be configured to facilitate or hamper rotation of the connector in a direction. Some embodiments can hamper tightening and facilitate loosening of the connector. Other embodiments can facilitate tightening and hamper loosening. Still other embodiments can hamper both tightening and loosening. Yet other embodiments can facilitate both tightening and loosening.Type: ApplicationFiled: March 26, 2009Publication date: October 1, 2009Applicant: ICU Medical INC.Inventors: John Seifert, Mark Lindsay, Jeffrey Woods

Patent number: 4969581Abstract: An unequivocal bottom delivery package with a self sealing valve for storing and dispensing a fluid material. The package has a shipping configuration in which a shipping cap is located over the self sealing valve to provide leakage resistance during shipment. Upon receipt it is obvious that operation of the package first necessitates removal of the shipping cap. Removal of the shipping cap transforms the package into a dispensing configuration. The dispensing configuration provides easy one step dispensing and makes it obvious that the container is intended to be stored with the self sealing valve between uses. A travel cap is provided for placement over the self sealing valve, transforming the package into a traveling configuration, which provides leakage resistance during subsequent transportation. It is obvious the package is not intended to be placed into the travelling configuration between every use.Type: GrantFiled: August 8, 1989Date of Patent: November 13, 1990Assignee: The Procter & Gamble CompanyInventors: John A. Seifert, Rocco D. Papalia, Craig F. Sampson, Christopher Loew
