Abstract: A braking system for a wind turbine is provided. The system includes one or more motors for driving a part of the wind turbine, a first group of brakes for braking the part of the wind turbine, and a second group of brakes for braking the part of the wind turbine. The first group of brakes is in a normally closed condition and the second group of brakes is in a normally open condition, so that a default brake torque can be selectively chosen that is less than a maximum brake torque.

Abstract: A dry cryogenic shipping container having a removable absorbent assembly is provided. The dry cryogenic shipping container is structured to be a Dewar's flask having a first, outer shell assembly, and second, inner shell assembly disposed within and spaced from the first, outer shell assembly, and a cap. Within the shipping container is an absorbent assembly having a body with a central cavity. The absorbent assembly body is formed by a plurality of removable absorbent assembly elements. That is the absorbent assembly elements are sized to pass through the passage into the space within the shipping container. As such, after use, the absorbent assembly body elements may be removed and the remaining components may be sterilized. After sterilization, new absorbent assembly body elements are inserted into the inner space and the dry cryogenic shipping container is used again.

Abstract: The invention relates to a stack of wipes for use in a wipes dispenser. The stack includes a plurality of wipes, each wipe of the plurality of wipes formed from a portion of a common material. Each wipe includes a leading edge portion with a pleat-like zone located along at least a portion of a length of the leading edge portion and the pleat-like zone is distinct from an adjoining main portion of each wipe. Each wipe is folded upon itself at least once and each wipe is positioned relative to adjacent wipes to form the stack of wipes.
