  • Patent number: 6736535
    Abstract: The act of heating water within a contained vessel that is common to most buildings, whether residential or commercial or located in recreational vehicles, mobile homes, aircraft, ships or marine pleasure craft, causes calcium carbonate to precipitate out and settle to the bottom of a heating or fluid containing vessel. The use of ultrasonic transmission within the vessel will agitate the water held within, preventing the normally stagnant hot water from producing calcium carbonate. Other benefits are the cleaning properties of ultrasonic transmission. Thus the internal parts of hot water heaters will enjoy a longer life. This benefit of agitation will also be found when applied to vessels that contain fluids that share similar problems as hot water heaters.

  • Patent number: 6491423
    Abstract: An apparatus for mixing particles in a liquid or semi-liquid medium, such as ceramic reinforcing particles in a molten metal or metal alloy matrix for the production of stir-cast metal matrix composite (MMC) materials. The particles can be introduced under the surface of the matrix by feeding the particles through the inner passage of a rotatable hollow impeller tube. The impeller tube is terminated at its lower end by an impeller head that includes teeth positioned proximate to an impeller base. The particles enter the matrix through a shear region in and around the volume between the impeller base and the impeller head. The rotating impeller and the high shear force thereby created wet the particles in the composite matrix and effect homogenization of the composite matrix. The present invention may be practiced either under vacuum or atmospheric pressure.

  • Patent number: 6196113
    Abstract: A versatile food appliance includes a set of hardware components common to a plurality of single-purpose food appliances. The set of hardware components is controlled by a microcontroller executing a program from a repertoire thereof stored in the general-purpose food appliance. Many processing programs are stored for operating the appliance in different modes and for processing different kinds of food by using different ingredients. Each processing program is assigned a code and can be selected by specifying the code associated with it from a control panel. The programs may be further modified parametrically by a group of process parameters. Ingredients to be used in each of the programs may be in a premixed form in a package with the code optionally labeled thereon. The repertoire of programs is updatable by the user. In the preferred embodiment, a memory card interface allows updated programs to be introduced via a removable flash memory card.

  • Patent number: 6012383
    Abstract: A kitchen appliance for preparing yogurt, soft frozen yogurt and ice cream, hard frozen yogurt and ice cream, and cheese. The appliance includes a housing having a base and side walls defining an open top. A motor-driven paddle device is rotationally journaled with respect to the cover and base and the motor therefor is adapted to be driven either continuously or with a predetermined duty cycle, dependent upon the product being made. Also mounted on either the cover or the base is a vent hole occluder that is normally positioned to block the vent holes in the cover or base, but which shifts to a second position uncovering those vent holes when the consistency of the product being produced, as tested by the paddle motion or other apparatus reveals that a predetermined cultured state has been reached. Shifting of the occluding device from the covering position to the open position also actuates a switch to shut off the drive motor and a warming element.

  • Patent number: 5993053
    Abstract: Electrographic toner fluid (15), contained in a reservoir (10), is convectively stirred through the application of a non-uniform thermal gradient by a heater (20). Convective flow in fluid (15) entrains colloidal particles (35) and other dissolved agents and causes them to be uniformly dispersed in the fluid (15), thus rendering the fluid (15) homogeneous and capable of making uniform prints. The heater (20) may be inside or outside the reservoir (10) and may comprise separate heaters, alternately or simultaneously energized.
