Patent number: 8311678Abstract: The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (“NDR”) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.Type: GrantFiled: June 23, 2010Date of Patent: November 13, 2012Assignee: Verifi LLCInventors: Eric Koehler, Mark F.

Patent number: 8070354Abstract: A system for mixing a bioprocessing fluid includes a container receiving the bioprocessing fluid and a support member supporting the container in an interior of a housing. A first channel is bounded by a first stationary arm and a second stationary arm with the first channel receiving the container. A first mixing arm and a second mixing arm are located in the interior. The first mixing arm is connected to the second mixing arm by a connecting member. The first mixing arm is located in the first channel and the second mixing arm is located in a second channel. The connecting member is movable to cause the first mixing arm to contact a first outer surface of the container to cause mixing of the bioprocessing fluid.Type: GrantFiled: February 5, 2008Date of Patent: December 6, 2011Inventors: Henry Robert Bungay, III, James Steele Bungay, John Graul Sigsby

Publication number: 20110273954Abstract: A mixing apparatus for mixing at least two components comprises a mixing chamber having a first component and at least one component chamber having a further component. The component chamber is connected to the mixing chamber by a feed line. A negative pressure device generates a negative pressure in the mixing chamber in the starting position. By activating the negative pressure device, the pressure is equalized, whereby the further component is transferred into the mixing chamber. A display apparatus is provided at the component chamber to display a pressure change in the component chamber. The display apparatus is preferably formed by elastic bellows provided at one end of the component chamber, which is disposed opposite of the end of the component chamber following the feed line.Type: ApplicationFiled: December 2, 2009Publication date: November 10, 2011Inventors: Andy Greter, Martin Veid, Rochus Stockli, Wilhelm A.

Patent number: 8052929Abstract: A receptacle having a plurality of interconnected chambers arranged to permit multiple process steps or processes to be performed independently or simultaneously. The receptacles are manufactured to separate liquid from dried reagents and to maintain the stability of the dried reagents. An immiscible liquid, such as an oil, is included to control loading of process materials, facilitate mixing and reconstitution of dried reagents, limit evaporation, control heating of reaction materials, concentrate solid support materials to prevent clogging of fluid connections, provide minimum volumes for fluid transfers, and to prevent process materials from sticking to chamber surfaces. The receptacles can be adapted for use in systems having a processing instrument that includes an actuator system for selectively moving fluid substances between chambers and a detector.Type: GrantFiled: April 1, 2011Date of Patent: November 8, 2011Assignees: Gen-Probe Incorporated, Qualigen, Inc.Inventors: Scott S. Breidenthal, Sara H. Fan, Richard S. Lee, Norman C. Nelson, Matthew J. Scott, Jason A. Taylor

Publication number: 20110267919Abstract: An internal batch mixer is provided with: a casing within which a material is mixed; a door which opens and closes a material discharge opening of the casing by being rotated about the axis thereof and closes the material discharge opening when in a closed state; and a latch mechanism which, when the material is mixed in the casing, holds the door in a latched state, the latched state being a state in which the material discharge opening is being closed by the door and cannot be opened, and which, when the material having been mixed in the casing is discharged from the inside of the casing, releases the door from the latched state. The latch mechanism is provided with a linear actuator which has a movable section capable of moving linearly and moves the movable section to the door side to supply power to the latch member, the power causing the latch member to move to the door side, and a linear sensor for measuring the distance of linear movement of the movable section caused by the linear actuator.Type: ApplicationFiled: January 7, 2010Publication date: November 3, 2011Applicant: Kabushiki Kaisha Kobe Seiko Sho (Kobe Steel, Ltd.)Inventors: Masaki Naoi, Yusuke Tanaka, Taro Uchida

Publication number: 20110249526Abstract: A process bag container is provided comprising a flexible bag, at least one inlet sealed to the bag, and an outlet. A probe housing for a probe construction is sealed to the bag. Preferably, the probe housing extends at least partway into the bag interior and is connected to a cable for power and data transmission that runs along the outer surface of the bag to the top of the bag or its support container. The probe construction is adapted to monitor the composition of a reagent in the bag as well as the environment within the bag. A mixer is positioned within the bag to effect mixing of reagents in the bag.Type: ApplicationFiled: March 9, 2011Publication date: October 13, 2011Inventor: Dennis Wong

Publication number: 20110235462Abstract: The disclosed apparatus, system and method relate to a shaft-actuated spindle mixer where the spindle mixer includes a motor and at least one motor switch enclosed in a mixer housing. A spindle shaft extends from the housing and is mechanically connected to the motor. The motor is mounted to a moveable mixer component such that the spindle shaft can be displaced to thereby causing the associated movement of the enclosed motor and moveable mixer component to which the motor is mounted. Movement of the movable mixer component actuates a switch. Actuating the switch causes the selective activation of the mixer motor. Activating the mixer motor rotates the spindle shaft. The disclosed apparatus and method provide for the optional one-handed operation of a spindle mixer, eliminate the need for a user or a cup to directly contact a switch to engage the spindle mixer, and further provides for the sanitary operation of a spindle mixer.Type: ApplicationFiled: March 22, 2011Publication date: September 29, 2011Inventors: Benjamin H. Branson, III, Ernest B. Pryor, JR., Michael G. Sandford, Brian Paul Williams, Ann Marie Blackmon
