  • Patent number: 6588930
    Abstract: A food mixer includes a head (12) that is detachable from a base (11) for use separately in mixing food such as cake ingredients. The turntable motor (25) in the base is controlled by an independent speed control (18). Control (18) and motor(25) receive their power from wires attached to a pair of electrically conductive hooks (32) which serve not only to physically secure the head (12) in position, but also to conduct the electric current.

  • Patent number: 6523994
    Abstract: A screw-threaded impeller 50 having a mixing device 55 thereon is provided in a container 10 of a food processor. A drive unit adjacent the bottom of the container is adapted to move the impeller in both a clockwise and a counterclockwise direction. During rotation, food placed within the container is lifted away from the mixing device when the impeller is rotated in one direction and is directed toward the mixing device when the impeller is rotated in the other direction. The mixing device includes a horizontal cutting blade 52 extending perpendicular to the impeller and a scooping blade 51 extending downwardly at an angle from the impeller. In order to lift over obstacles, the mixing device is spring mounted or can move along the helical protrusion toward the upper end of the impeller.

  • Publication number: 20020141286
    Abstract: A blender having a base, a container, and a blade base includes a motor, a microcontroller, memory, a sensor and a user interface. The blade base connects the container to the base and includes a blade unit having at least a first blade and a second blade of a different design from the first blade. The microcontroller is in communication with the memory, sensor, motor, and user interface. Programs with preprogrammed motor commands for desired operations are stored in the memory. The user interface includes a liquid crystal display, or function switches and light emitting diodes. Upon selection of a particular pre-defined function, the microcontroller retrieves the appropriate program from the read only memory and specifies the preprogrammed motor commands to accomplish the selected function.

  • Patent number: 6331070
    Abstract: The invention apparatus comprises a mixing vessel closure having rotating mixing blades secured thereto. The mixing blades are driven through an axially engaged and disengaged direct coupling. The closure is mounted on a power base structure for rotation about an axis that is substantially transverse of the mixing blade axis. Additionally, the closure mounting includes a translational drive for linearly raising and lowering the closure at each of two positions about the transverse axis. A portable mixing vessel including a material charge is placed under the vessel closure. The closure is translated down to a sealed cover position over a vessel opening and secured to the vessel. The unitized assembly of the closure and vessel is translated away from a vessel supporting transport base and rotated to a inverted position. The unitized assembly is then translated down to engage a rotatory power transmission coupling.

  • Patent number: 5855431
    Abstract: A rotating mixer for mixing drinks utilizes a tumbler-type container attached to a base and a rotatable whisk. The whisk is turned by rotatable gears, one of which is attached to a motor and one of which is attached to the base of the container. The motor is housed in a motor housing unit and is powered by batteries, or, alternatively, by an AC adapter. The motor housing unit includes a collar that is inserted into a sleeve in the bottom of the container base to provide a stable guide for aligning the motor gear and whisk gear. The detachable base also provides a stable platform for the container when it is not engaged with the motor housing unit. The detachable base may be a lightweight, yet sturdy, two-piece unit comprising a sleeve section and a coupling section. The motor housing unit fits into a tray which is adapted for use as a serving tray and which also functions as a battery recharger when plugged into an electrical outlet. The tray comprises holders for holding one or more containers.

  • Patent number: 4792236
    Abstract: A paint tinter system includes a plurality of canisters disposed in a circle about a rotatable plate. An orbiting plate, driven by a single motor, is connected to drive arms, each of which is connected to a crank arm of a stirrer in one of the canisters. The connection is made through a lost-motion device in a cap covering each canister. The cap captures the end of the drive arm, whereby the cap may be removed and hinged out of the way for providing access to the canister. An impeller is freely mounted for rotation in a socket in the bottom of the canister. The upper end of the impeller is driven by engagement between a pair of driver bosses rotated by the crank and edges of a top plate on the canister. Thus, when the cover is removed, the impeller may remain unmoved or be lifted from the socket for cleaning.

  • Patent number: 4403867
    Abstract: An emulsification tester for determining the amount of water a known amount of material such as printers ink or shellac will absorb when agitated or mixed a precise number of times and in a precise manner is disclosed. As is well known by those skilled in the art, certain materials, especially materials such as shellac and printers ink, will not function properly unless these materials have the ability to absorb a proper amount of water. That is, the material must be able to absorb a minimum amount of water but must not absorb an excess amount of water. The tester of this invention allows a precise amount of water and a material to be tested (such as printer ink) to be agitated by mixer blades rotating at a precise selected speed and for a precise number of revolutions.
