Abstract: The present invention relates to a coffee-brew percolator. The percolator comprises an outer vessel, a bottomless boiler slidably and removably arranged in the vessel, and one or more filters designed to confine in the vessel a space above the boiler for accommodating coffee powder. The boiler has one or more calibrated openings or holes through which steam or vapor can be discharged in use. The boiler is free to slightly move towards and away from the space containing coffee powder so that the latter is packed and amounts of water calibrated in accordance with the pressure level in the boiler are released from the bottom of the boiler towards the coffee powder in the space.

Abstract: An automatic paste-producing apparatus which includes a vertical assembly constituted by a tubular chamber whose upper end communicates with a metering tube of enlarged diameter to which flour or other powder is supplied. Coaxially mounted within the assembly is a rotating shaft having a main screw section of uniform diameter operating within the chamber and a conical screw section operating within the metering tube. Slidable within the metering tube is a ring which surrounds the conical screw section to define an annular valve orifice, the ring being axially shiftable to set the size of the orifice. The flour admitted into the chamber by the metering tube is hurled by the main screw section against the inner wall of the chamber to create a thin powder film thereon which is then intermixed with a liquid to form a paste, air being drawn from the chamber through the main screw section to control the entrainment of air within the paste.

Abstract: A product such as ground meat is efficiently chilled in a blender device having an open top. Liquid carbon dioxide is introduced into the blender at a location below the surface of the product to thereby form solid and gaseous CO.sub.2. Mixing elements such as a ribbon screw or the like are operated to pass the product in a countercurrent relation to the carbon dioxide introduced into the blender thereby chilling the product and causing the resulting CO.sub.2 gas to rise along one wall of the blender. Deflector means are provided along such wall to direct the rising vapor toward an exhaust plenum located above the open top of the blender.

Abstract: A turbine rotor structure is disclosed in which shrink-fitted turbine wheels are keyed to the turbine shaft to prevent rotation of the wheels with respect to the shaft in the event of any loosening of the shrink fit. In a preferred arrangement, the rotatable shaft of the turbine is provided with an integral flange, near one end, having two diametrically opposed, notched keyways formed at peripheral locations thereon. Each wheel of the set of wheels used to carry the turbine buckets includes an integral, central hub which extends axially to both sides of the wheel. Further, each hub has pairs of complementary keys and keyways whose members are axially opposite each other at peripheral locations on the wheel hubs. Thus, the key of the first wheel on the shaft mates with the keyway of the integral flange of the shaft and subsequently added wheels mate with each other.
