  • Patent number: 6033102
    Abstract: A method and a system for controlling the mixing of raw materials for cement. Component contents of a sample material is obtained at an exit side of a mill system to obtain measured modulus values of hydraulic modulus HM, silica modulus SM, and iron modulus IM of a raw material mixture. Estimated modulus values of the component contents is determined and based on current takeout amounts of the raw materials, a mill system passage characteristic model, a component analyzer passage characteristic model, and preset component contents of the raw materials. Modulus deviation values are calculated based on differences between the estimated modulus values and the measured modulus values, and is passed through a noise removal filter. Future modulus values of the component contents are then calculated based on the raw material takeout amounts, and the preset raw material component contents. To determine predicted modulus values for calculation of updated takeout amounts.

  • Patent number: 6017022
    Abstract: Shear mixing apparatuses and associated methods are disclosed for producing small gas bubbles of a diameter of less than about 0.1 millimeters in a liquid, whereby mass transfer of the gas into the liquid is improved (as compared to the mass transfer achieved by conventional large bubble generators under the same circumstances) in applications benefiting by such improved mass transfer, involving injecting a gas under pressure via one or more orifices into a liquid that is flowing at a velocity sufficient to cause bubbles formed at the orifice(s) to subdivide to the desired small bubble size.

  • Patent number: 5342125
    Abstract: A feedscrew for an extruder or molding apparatus has an elongated body with a helical thread formed thereon defining a first channel "A ". At the start of a mixing section, a channel "B " is cut in the center of the channel "A " and both channels are of the same pitch. The channels start at the same depth, but the channel A decreases in depth to a minimum and the channel B increases in depth to a maximum. The channel B then decreases in depth to a minimum and the channel A increases in depth to a maximum where the channels are again at the same depth. This channel within a channel configuration is repeated along the mixing section. The purpose of the arrangement is to compress and decompress the material being fed through the assembly to obtain the desired mixing action for low shear homogenization of the viscous plastic polymer.

  • Patent number: 5188455
    Abstract: An apparatus for mixing fluids is described which includes a flexible tubular member disposed between opposed ends. Filling and clamp systems are placed adjacent each of the opposed ends, creating sealed chambers in the tubular member, each chamber including a reagent fluid. The sealed reagent chambers are separated by a mixing chamber, and all of the chambers are disposed within the tubular member. A spring driven plate pressurizes each of the reagent chambers. A control system is coupled to each of the clamp systems for selectively opening a channel between at least one reagent chamber and the mixing chamber, with reagent in a reagent chamber being forced, via the open channel, into the mixing chamber by the spring biased pressurizing plate.

  • Patent number: 5167448
    Abstract: A mixing apparatus for pastes comprises a mount (18) for a mixing container (19) supported on a rotor (10) for rotation relative to the rotor about an axis (16) which is eccentric with respect to the rotor axis (15). During a mixing phase, a transmission (20 . . . 22) causes the mount (18) to rotate about its eccentric axis (16) so that the mixing container (19) executes an overall circulatory reciprocation and the container contents (29) are subjected to a shaking motion. For a subsequent compression phase, the transmission (20 . . . 22) is switched-over while the rotor (10) continues to rotate, so that the mount (18) is now free to assume an orientation that is fixed with respect to the rotor (10) and in which the mixed paste is forced against a dispensing piston (55) provided in the container (19) and is thereby degassed.

  • Patent number: 5161281
    Abstract: An apparatus for cleaning the rim of a vehicle which including a buffer wheel head mounted adjacent a wheel mounting device and being pivotable toward the rim about a first axis which is parallel to the axis of rotation of the wheel. The buffer wheel head includes a pair of buffer wheel mounted on a drive shaft in the buffer wheel head, at least one of the buffer wheels being axially adjustable on the shaft so that the pair of buffer wheels can be positioned immediately within the side flanges of the rim. The head is pivotally about another axis spaced from and perpendicular to the first axis so as to allow the pair of buffer wheels to swivel to turn the buffer wheels at a slight angle relative to the side flanges first to one side and then to the other to thereby simultaneous engage both flanges with an enhanced buffing action.

  • Patent number: 5156082
    Abstract: A rice cooker includes an interlock that prevents the user from sliding the cooking pot out of the cooker without first disengaging internal assemblies that would otherwise be damaged. The rice cooker operates in any of three user selectable modes: a fully automatic mode in which the rice cooker measures out a user selected quantity of internally stored raw, unwashed rice, washes the rice, cooks the rice and then keeps the rice warm; a cook and keep-warm in which the cooking pot of the rice cooker is loaded with premeasured and washed rice from an external source and the rice cooker cooks the rice and keeps it rice warm; and a rice warming mode in which the cooking pot is loaded with already cooked rice and maintains it at a serving temperature. A startup routine checks that a pot is installed, that a lid is on the pot, that an upper pot cover assembly is at a required height, that a platform is in its latched position, and that a washer container is in its stowed position.

  • Patent number: 5147280
    Abstract: A centrifugal separator having a device for the transformation of kinetic energy of a liquid rotating in a chamber (12) to pressure energy comprising a discharge element (17) for the discharge of liquid out of the chamber. The discharge element (17) has a surface (20) arranged to be so located in the rotating liquid body that liquid flows in a predetermined direction along and in contact with the surface (20). The discharge element (17) forms an outlet channel (19) having an inlet opening (22) located in said surface (20), and limited downstreams by a cross edge (25) from which the outlet channel (19) extends a bit essentially in said predetermined direction. An increased outlet pressure is achieved by the fact that at least two passages (27, 28) are arranged in the discharge element (17) connecting a part each of the outlet channel located at axial ends of the cross edge (25), respectively, to the chamber (12) in such a manner that liquid flows through the passages (27, 28 ).

  • Patent number: 5074670
    Abstract: An integrated process blending apparatus which blends particulate material and is also adaptable to store blender inventory to thereby integrate process feed with the blending function. The apparatus comprises a fluidized bed blending means to preblend that raw feed which is not send directly to the gravity blender. Overflow from the fluidized bed means is directed into a storage chamber means from which it can be withdrawn upon demand and sent into the blender. The blender is also made more effective by dividing it into vertical compartments with separators which have angled portions preferably in their lower regions to cause different downward flow velocities in each compartment, and by creating a multistage blender by stacking sets of offset compartments one on top of another.

  • Patent number: 5060339
    Abstract: A blower attachment for a vacuum cleaner including an attached member disposed over the exhaust air discharge openings that extend around the vacuum cleaner casing. The attached member includes a strap section that extends over and blocks air flow from some of the discharge openings, and a plenum section that extends over and receives the flow of air from the remaining unblocked discharge openings. The plenum section tapers from the inlet port to an air output orifice that may be connected by conventional methods to inflate any of a number of devices that require a high volume of low pressure air. Tabs extending inward from the attached member are received in corresponding discharge openings to secure the attached member to the casing in an aligned position over the discharge openings.
