A mixing system has a single-use container (1) with flexible walls and a mixing device. The mixing device has at least one encapsulated drive (5) and a mixer shaft (3). The drive (5) can be disposed of after use together with the mixer shaft (3) and the single-use container (1). The mixing system can be used in biotechnology and the pharmaceutical industry for mixing liquids, dissolving solids or cultivating cells and microorganisms.

An auger protection system used in a stirring system is disclosed. According to a first preferred embodiment, an auger protection system is provided which protects augers on a stirring machine from breaking or bending. Accordingly to this first preferred embodiment, the auger protection system includes a switch which is enclosed in a housing and connected to a timer which supplies power to a gear motor that propels the unit around a silo. Preferably, the housing for the holding switch is attached pivotally to the structure on which the down auger is connected. Additionally, the auger protection system preferably further includes a spring which is connected to a pivot assembly and which extends horizontally and comes in contact with the down auger at one end.

The invention relates to a stirring device for wastewater includes a drive device having a drive shaft extending vertically therefrom in the assembled state, a stirring body mounted on the drive shaft, and a safety bearing, in which a free end of the drive shaft is rotatably held. In order to avoid damage to the stirring device, in accordance with the invention a slide sleeve to be mounted on the free end of the drive shaft, and for a device for detecting a state of wear of the slide sleeve is provided.

An inerting system for an aircraft and a method of inerting a hydrogen system in an aircraft. Also an aircraft with such an inert system. In the inerting system, a part of an inerting gas that has already been supplied to the casing of the hydrogen system is mixed with pure inerting gas through a fluid recirculation system.

A blender for home or commercial use that is rugged enough to blend frozen beverages, simple to use and safe. The blender includes an upper housing with a front housing door that covers the moving blending machinery. The blender also includes a cupholder receiving area which allows the user to safely insert a frozen food or beverage cup inside a cupholder for blending. After the start button is pressed, the cup and cupholder will be lifted together for blending in a balanced, linear motion by an elevator assembly. Dual lead screws or a dual belt drive are preferably used in the elevator assembly to achieve this balanced, linear motion. As the cupholder is lifted upward, a cover will be pressed over the top opening of the inserted cup to prevent spillage during blending. The elevator assembly continues to lift the cupholder upward until the rotating cutter blades of a spindle assembly cut through successive layers of the frozen food or beverage. To facilitate cleaning, the spindle assembly is preferably removable from the blender through use of a quick release coupling mechanism.

A blender includes a base unit having a receiving well, a container assembly and an actuation arrangement. The container assembly includes a container body having a blending cavity and a rim, and a connector member detachably attached on the container body to selectively seal the blending cavity, a driven unit and a blending blade. The actuation arrangement includes a plurality of actuating members outwardly extended from the rim of the container body, a plurality of actuating slots indently and spacedly formed along a side wall of the receiving well, and a plurality of actuating switches. When the connector member is slightly rotated in the receiving well, each of the actuating members is arranged to circumferentially move along the corresponding actuating slot so as to actuate the actuating switches for actuating the driving head to rotate.

A modular barrel storage and mixing system. Each module is designed to hold a 600 lb barrel, and the modules may be stacked up to 3 units high, with interlocking components for stability. Agitation of each barrel is controlled pneumatically, using a pressure regulator and drier, an emergency cutoff control valve, a pneumatic variable timer, a 3-way directional control valve, a limit switch and a pneumatic cylinder.
