Abstract: Disclosed is a device for intermittently conveying packages which are conveyed in a first moving direction in package carriers (2) in a first processing plane in positions underneath various treatment stations and are conveyed back in a second return motion plane in a second moving direction that is parallel in relation to the first moving direction, whereby a conveying cycle is formed. The aim of the invention is to enable such a device to be efficient, compact and be operated using simple devices. According to the invention, the respectively superimposed ends of the essentially horizontal first conveyor (19) in the first processing plane and of the essentially horizontal third conveyor (12) in the second return motion plane are connected to one another for forming the conveying cycle by means of vertically acting second and fourth lifting conveyors (9, 15). Each conveyor (9, 19, 12, 15) has a separate drive (22-24).

Abstract: The invention relates to a ring conveyor for conveying bulk material, especially brewing barley or long malt, from a feed pipe fitted permanently inside a building in the form of an annular tower and opening above the ring conveyor into the region of a radial charging and discharging machine circulating above a kiln floor. The ring conveyor has a circular base and a closed rotary ring, open-edged at its outer periphery, arranged coaxially with the floor and with a substantially vertically adjoining inner wall at its inner periphery. There is also a doctor blade firmly secured to the charging and discharging machine, engaging in the rotary ring and diverting the bulk material to the charging and discharging machine. The rotary ring turns at a higher cycle frequency than the charging and discharging machine.

A discharge device (21) is rotatably arranged in the channel or in each channel and is provided with recesses for accommodating material in the silo and for moving this material to a position in which it can be discharged from the silo. The discharge device or devices (21) suitably has/have the form of a cylinder provided with axially or helically cut grooves, these grooves forming the aforementioned recesses. A pillar (3) extends centrally through the silo (1), from the disc (15) to an inlet opening (4) in the top of the silo (1).

Abstract: A screw seal for conveying bulk particulate solids between spaces at differing gas pressures with minimal leakage of gas. A tubular housing encloses a screw conveyor section and a sealing section receiving the solids and forming a sealing plug. The sealing section has a divergent configuration that functions in combination with friction to create sufficient solids pressure with minimal driving torque and wear on the screw conveyor.

Abstract: The invention relates to the cocurrent gasification of coal and to a gas generator. The gas generator (11) comprises a vertical sealed vessel, the lower third of which is divided into several identical vertical compartments (12). Coal is loaded at the top (17). The major part of the hot reactive gas under pressure is introduced at the top (18), and the remaining part at lower levels (21, 22). Gas evacuation (24) is stopped from one compartment (12) in turn, gas produced is blown in order to unclog the filters (25, 26) and to loosen the ash, the ash is extracted at the bottom (23) and cold reactive gas is blown countercurrently in order to complete the combustion and to cool the ash. This gas generator enables coal from any source to be used and does not require purification downstream.

A plurality of hollow, fluid cooled flights are affixed to the outer shaft and are in fluid flow communication with coolant coursing through the screw. The coolant is first directed through the flights and then back through the outer shaft before exiting through the inner tube.

Abstract: A device is described for directly making liquid pig-iron from coarse iron ore. Hot sponge-iron particles are directly conveyed by a worm conveyor (17) through a communicating passage (19) from a direct-reduction blast-furnace shaft (2) into a smelter-gasifier (1), and a stream (24) of gas flows, after cooling to below 950.degree.

Abstract: Apparatus for discharging hot flowable solids comprises conical conveyor screws, which are arranged to form a star-shaped array and contained in respective conveyor troughs and at their inner ends are rotatably mounted in a centrally disposed hollow body. In order to ensure a gas-tight seal of the furnace and to permit a simple replacement of the conveyor screws, the conveyor troughs and the centrally disposed, open-bottomed hollow body are constituted by a bottom structure, which is adapted to be flange-connected to the shell of the furnace. The largest depth of each conveyor trough is at least as large as the largest outside diameter of the associated conveyor screw. Each conveyor trough is closed at its outer end by an end wall, which carries a discharge housing, which contains the outer end of the associated conveyor screw and carries a discharge fitting.

Abstract: Pieces of shredded tires are fed into the top of a vertical pyrolyzing furnace in a measured amount using a weighing hopper feed mechanism. Heated gas is introduced through inlet and pyrolyzing the tire pieces on a countercurrent flow principle to produce useful hydrocarbon volatiles and residues. The pyrolyzed residue including tire reinforcing wires are efficiently removed from the furnace by a plurality of downwardly inclined screw conveyors disposed in troughs. Each screw conveyor extends into an inclined conduit and discharges into a vertical branch conduit disposed at least partially within the cross-section of the furnace so that even discharge of the pyrolyzed residue is ensured by the combined action of gravity and the screw conveyors.

Abstract: A control system for a grain drying bin includes a pre-dry sensor mounted on the inside of a grain drying bin a short distance above the floor and a thermocouple grain temperature sensor mounted in the discharge tube of the grain drying bin. The discharge grain temperature sensor includes a thermal contact member made of copper or other heat conductive material having a thermocouple bonded thereto to intimate heat conducting relationship. The thermal contact member is mounted by a mounting block to the discharge tube to extend through a slot into the interior of the tube and is shaped to allow the grain to flow around it in thermal contact therewith. A gap is provided in the fighting of the discharge auger in order to provide clearance for the thermal contact member. The control system prevents discharge of grain until the pre-dry temperature is attained, and controls stopping of the grain discharge, in either a sample mode or a discharge mode, if the discharged grain is too cool.
