Composition and method for gel electrophoresis with in-situ calibration
Patent No. 9,005,419
The invention relates to, among other things, a method for performing electrophoresis with in-situ calibration. The method includes combining a volume of a test sample with a volume or quantity of a calibrating sample to form a final volume, where the volume of the calibrating sample includes a known concentration of a calibrator and the final volume includes a known ratio of test sample to calibrating sample. The method also includes depositing a loading fraction in a receiving well of an electrophoretic gel, in which the loading fraction is a fraction of the final volume, and separating the loading fraction along a common separation lane of the electrophoretic gel such that components of the test sample and the calibrator are separated from one another along the common separation lane. The method also includes detecting the calibrator and separated components of the test sample within the common separation lane and measuring the level of the calibrator and separated components of the test sample based on the detecting, thereby performing electrophoresis with in-situ calibration.

Mineral slurry drying method and system
Patent No. 9,004,284
The present invention provides methods and systems for reducing moisture in mineral slurries, particularly mineral slurries containing minerals of small particle diameter, using a granular drying material. The invention also relates to novel mineral products and intermediates useful in connection with the process. The method and system reduced moisture by contacting the mineral slurry with the granular drying material. The granular drying material is selected to be readily separated from the dried minerals using a size separation technique such as a sieve screen. The granular drying material is the regenerated, preferably using a process involving heat exchange and cross-flow air. The granular drying material is preferably capable of regeneration and recycling in a continuous process with minimal attrition.

Method for forming a smoking article capable of delivering flavorant to mainstream smoke when ignited during smoking
Patent No. 9,011,603
Delivery of additives in a smoking article is provided through thermally degradable, robust immobilized additive inserts. Additives can be immobilized in an elongated device or an insert, wherein the elongated device or the insert is sufficiently robust to allow the elongated device or the insert to be manually or machine inserted into a smoking article while maintaining the structure of the elongated device or the insert. By providing additives in the form of thermally degradable immobilized additive inserts, migration and/or loss of the additives in a smoking article prior to smoking can be reduced.

Fuel composition containing a hydrocarbyl-substituted succinimide
Patent No. 9,011,556
The present disclosure is directed to a middle distillate fuel composition comprising a friction modifying effective amount of a hydrocarbyl-substituted succinimide derived from maleic anhydride, polyisobutylene and ammonia; and a middle distillate fuel. A method for modifying friction in a compression engine comprising providing to the engine the disclosed fuel composition is also disclosed. Moreover, there is disclosed a method for improving fuel mileage.

Shaft-actuated spindle mixer
Patent No. 9,010,990
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.

Loose fill tray packaging system
Patent No. 9,010,571
Disclosed is a packaging system (10) for containing and dispensing loose filled product units. An inverted tray (20) is sealed to a backer board (40) with a guide insert disposed there between defining an interior chamber that is also filled with product units. The guide insert may include a base flange (38), a pair of side flanges for funneling product units into the truncated area that defines a next dispensing position. A flexible bridge (34) includes at least one high point and a fence portion that can descend into the base flange upon application of sufficient pressure to the at least one high point. This allows a product unit to advance to a dispensing position such that product units can be dispensed one at a time through user manipulation of the flexible bridge.
