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 blending appliance includes a housing with a jar receiving area defined between an upper housing and a support base. A blender jar includes a base portion and a receptacle portion, and is configured to be laterally received within the jar receiving area of the housing. A magnetic coupling system includes an upper magnetic coupler disposed in the base portion of the blender jar and a lower magnetic coupler disposed in the support base of the housing. The upper and lower magnetic couplers are magnetically coupled to one another for driving a blade assembly disposed in the receptacle portion of the blender jar. A brake mechanism is disposed on the upper magnetic coupler and is configured to stop rotation of the upper magnetic coupler when the blender jar is removed from the jar receiving area.

A mixing apparatus (1) for mixing slaughter offal with a preservative agent, the apparatus comprising an offal collection tank (3) with a bottom (4) provided with a discharge opening (5) connectable to a closable discharge, an agitator (8) extending into the offal collection tank, and a pump unit (9) operatively connectable to the discharge, wherein the apparatus further comprises a preservative reservoir (7) mounted on top of the collection tank (3). A collection and preservation system is provided, wherein the addition of preservation agent can be strictly controlled, can easily and quickly be installed and connected when it is to be used. After use, the system is easily removed and cleaned.

A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.

A safety and injection system for adding an additive to fuel in a fuel chamber, includes a portable additive source having a body, an additive chamber, a memory, a fuel inlet, and a fuel outlet. The system can also include a fuel inlet valve which is connected to the fuel chamber, and includes a connector for connecting to the fuel inlet; a fuel outlet valve which is connected to the fuel chamber and including a connector for connecting to the fuel outlet. The system can further include a platform having a memory reader/writer that reads the information in memory and is capable of writing information on memory, and on which the portable additive source is placed; and at least one control unit which is connected with the memory reader/writer, which includes a user interface device for receiving control information from the user, and which controls the operation of the safety and injection system.
