Abstract: A stacking apparatus comprising a rotatable stacking wheel with a multiplicity of fingers, of which one end is fastened on the circumference of a hub, enclosing a stacking-wheel spindle and between which there is formed in each case one receiving gap for sheet-like articles, said stacking apparatus being characterized in that the width of the receiving gap can be adjusted between an open position, in which the sheet-like articles can be introduced into the gap, and a position in which the sheet-like articles are retained.

Abstract: A rotary feeder includes a housing which accommodates a rotor extending between two lateral disk members. Bearing against the peripheral area of each disk member is a slide ring which is acted upon by a pressure fluid with a constant holding force by which the slide ring is pressed against the associated disk member. Thus, the axial sealing of the rotor within the housing is independent of the wear of the slide ring. In addition to the holding pressure, the slide rings may also be subjected to a momentary displacement force which exceeds the holding force and ensures that the slide rings overcome frictional forces in the area of their guides.

Abstract: An apparatus for charging refuse into an incinerator comprising a housing and a drum disposed in the housing for rotation about a horizontal axis, the housing having an inlet communicable with an elevated mass of refuse for guiding the refuse into the housing and depositing it on a periphery of the drum and an outlet communicable with an incinerator at a lower level, and the housing having a wall spaced from the periphery of the drum defining a passageway intercommunicating the inlet and outlet of the housing whereby upon refuse being guided through the inlet and deposited on the periphery of the drum and the drum being rotated, the refuse deposited on the periphery of the drum will be conveyed through the passageway by the drum and discharged through the housing outlet.

Abstract: A solder feeding system including an apparatus for supplying a predetermined number of solder balls to at least one soldering bath once the level of liquid solder in the bath drops below a defined limit. The solder ball is shaped to have a diameter of from 5 mm to 50 mm, preferably 10 mm to 30 mm by casting, forging, or rolling. The number of solder balls added have a volume capable of raising the level of liquid solder in the bath by a distance similar to or less than a range of tolerable upper and lower limits and a thermal capacity to lower the temperature of the liquid solder within a tolerable range.

Abstract: The invention relates to a bucket wheel valve heated by hot gas flowing through an axial gas chamber in a rotor which is spaced axially from the side walls of a housing. The spaces between the rotor and the side walls are screened from the exterior in the radial direction by annular members forming extensions of the chamber.

Abstract: The novel gasification reactor comprises a vertically oriented chamber with an upper pyrolysis section, a lower feed opening, and a primary combustion section. A lateral passage on each side and near the top of said primary combustion section each communicates with a separate secondary reaction chamber where a partially reacted feed is further reacted to form the product gas. In each passageway is a venturi nozzle or preferably a plurality of nozzles which accelerates the gas carrying entrained carbonaceous materials to produce a swirling curvilinear motion in the secondary reaction chambers.The reactor is fed by means of a plurality of hoppers and screw conveyors whereby the flow is regulated and positively fed both by gravity and the screw conveyors into rotary valve cavities in which counter rotating valves travel. The valves feed a piston which charges the reactor.
