Abstract: The invention provides a chemical mixture device that avoids the mixing of large batches of chemicals and provides a continuous and precisely mixed mixture. For mixing water and a chemical, a large water tank and a chemical tank supply water and chemicals to first and second mixing tanks. As small batches are mixed in one mixing tank, the mixture is drawn from the other mixing tank.

Abstract: Method for mixing granulates, powders and liquids in a continuous process, whereby the material is placed in a mixing housing and is mixed therein with the aid of a rotor equipped with mixing arms. The material is thereby moved to and fro many times during one rotation of the rotor, towards the rotor axis and away from it. For that purpose the device with which the method is implemented has longitudinal stators, mounted principally in the axial direction of the rotor, between which the mixing arms move when in operation. The mixing housing consists preferably of two chambers situated behind one another seen in the direction of the axis of the rotor and separated from one another by the rotor disk. The material which is to be mixed enters the housing in the first chamber, where it is undergoes a preliminary mix, then flows into the second chamber and is mixed further there.

Abstract: A rotatably driveable enhanced-flow impeller system has a radial flow impeller with a first impeller face disposed proximate the bottom of the tank and proximate or extending into an inlet port for liquids in the tank bottom. The radial flow impeller has a plurality of blades with radially outermost blade tips terminating along a blade terminating circle. The blades and inlet port are contoured to reduce shear stress on the liquids. Disposed adjacent a second opposing face of the radial flow impeller is a radial flow extension plate which preferably extends radially outwardly along the second face by a radial distance beyond the blade terminating circle. The radial flow extension plate may be fixedly attached to the second impeller face.

Abstract: A system and a process is provided for reducing the dust formation during the transfer of a particulate material on an endless conveyor belt. During transfer of the material on the conveyor belt the material is first sprayed with a wetting agent then by application of a plow the moving material is lifted from the bottom of the belt and is diverted towards the side edges of the belt thus creating additional exposed surfaces. The material is then again sprayed then contacted with baffles to redirect the material from the side edges towards the center of the belt thus creating additional exposed surfaces which are then again sprayed with a wetting agent to substantially eliminate dusting. The plow and baffle combination can also be used for uniformly mixing two or more particulate materials on a moving belt.

Abstract: The invention relates to a multiscrew, continuous mixing machine for plasticizable compounds with two screws, which rotate in a housing and which penetrate the cylindrical part of the housing that envelops the screw concerned and exhibit feed and metering sections and inbetween at least one homogenizing section and a mixing section, whereby the feed and metering sections are formed by intermeshing conveying screws, which rotate in the same direction and are arranged in the mixing elements, which are opposite the homogenizing and mixing sections and whose edges travel past each other with little clearance while rotating, whereby to form a chamber extending above the mixing elements, the edges maintain a distance from the part of the housing enveloping said edges that is significantly greater than the clearance.

Abstract: Homogenizing pressures are reduced by providing three homogenizing valves in series. The addition of a holding chamber between the first and second stages which provides a dwell time in the order of seconds can further reduce the pressure requirements or improve product quality for a given pressure.

Additionally a work station is provided that houses the apparatus of the present invention and allows the user to complete the mixing and extracting process without removing the vessels from the holding tray.

Abstract: There is described an apparatus for preparing a beverage, in particular coffee, of the type wherein an electric motor drives a piston in a filling chamber. In accordance with the invention, the motor power is controlled with a closed loop control, so that the rotational speed can be held constant and the attainment of an end position of the piston can be detected from the increase of the motor power required, without requiring elements mounted on parts which are to be cleaned regularly.Preferably, the apparatus is adapted to slightly press the coffee powder by means of the piston, and to slightly squeeze out the residual dregs, after the coffee-making process has ended, by means of the piston.

Abstract: A concrete mixer having a mixing drum constructed of high density crosslink polyethylene material. The drum includes a bottom supported by a conventional rigid metal pan secured to the external surface thereof to rigidify the plastic drum and extend the life expectancy of the plastic drum by enabling the concrete mixer to be used to complete a mixing job at a job site even though movement of the concrete mix within the drum during repetitive mixing cycles may ultimately wear a hole through the bottom of the plastic drum. Paddle assemblies are positioned interiorly of the drum and oriented to maintain minimum splashing during the mixing operation. A rigid ring gear is attached peripherally of the drum in spaced relation to the metal supporting pan with the drum, ring gear and metal bottom pan being uniquely related to facilitate assembly and disassembly of the components to facilitate easy replacement of the components.

Abstract: An automatic espresso and cappuccino machine comprises a number of individual filter units movable with respect to a coffee filling station, a coffee dispensing station, a filter cleaning station and a filter washing station. Ground coffee is introduced into each filter unit at the coffee filling station and then the filter units are selectively rotated by a filter indexing device to the coffee dispensing station where they are moved into engagement with a water nozzle which first compacts the coffee and then directs heated water through the ground coffee to form espresso. An emulisifier is also located at the coffee dispensing station, which is effective to produce foamed milk for combination with the espresso to form cappuccino.

Abstract: In a first embodiment, a beverage brewing machine has a reservoir in which water is heated, which is arranged upstream of a brewing unit and heatable by an electric heating device. At the bottom is an outlet valve which opens only on reaching a given water temperature so that the hot water flows through an outlet pipe downstream of the outlet valve from the reservoir over the upper surface of a product, preferably ground coffee or tea-leaves, contained in a brewing unit, from which it goes to a receptacle as a beverage after extraction of the product. Hot water from the reservoir can also be taken via a pipe along paths other than over the upper surface of the product into the receptacle. The pipe takes a siphon-like path, the vertex of which is far enough above the bottom of the reservoir so that hot water also flows via the pipe to the other path and not only over the upper surface of the product only when a certain level is reached in the reservoir.
