Abstract: A gear pump assisted screw conveyor extrusion system utilizing a cartridge heating device disposed axially within the screw and having the drives for the gear pump and the screw correlated in speed to create relatively little pressure in the thermoplastic material being extruded such that relatively little mechanical working thereof occurs. The thermoplastic material is melted in the screw conveyor primarily by heat transfer from the cartridge heater and the gear pump is utilized for conveying the melted material under pressure to a subsequent work station. A relatively deep material-conveying spiral channel is provided in the screw for maximized extrusion output per revolution of the screw and minimized mechanical energy generation by the screw. A motionless mixer may be employed intermediate the screw and the work station to homogenize the melted material for reducing temperature gradients therein. The system advantageously is capable of extruding material at a substantially greater rate and a lower material temperature and with substantially increased power economy than conventional systems utilizing a high pressure, externally heated screw conveyor portion.

Abstract: Apparatus for collating and stacking building components, for example tiles, has pairs of conveyors with shelves for supporting edges of tiles. The tiles are fed to the shelves by a conveyor and the pairs of conveyors move upwardly in timed relation to locate tiles on the shelves. When all the shelves are full, the pairs of conveyors move downwards and apart to deposit the tiles in a stack on to a support. The timing of this avoids shock loads on the tiles. The stack of components is then banded and removed from the apparatus.

Abstract: A steam dryer for pressed fibrous material, such as sugar beet cossettes, has a pressurized, horizontally arranged pipe or drum (1) closed at both ends and provided with a diametrically opposed supply manifold and exhaust manifold piping (5, 6) for the steam. At least one heat exchanger (7) is arranged in a lengthwise half of the pressurized pipe and extends across the entire steam flow-through cross-section. Endless loop screen or mesh belts (8, 8', 8'') are arranged one above the other in the other lengthwise half of the pressurized pipe. These belts are driveable in opposite directions for conveying the material to be dried, and to transfer the material from an upper belt to a lower belt. The mesh belts (8) define separation planes between pressure and exhaust chambers (24, 25) which are alternatingly arranged above and below each respective mesh belt. The pressure chambers (24) comprise inflow cross-sections open to the lengthwise half with the heat exchanger (7), and the exhaust chambers (25) comprise outflow cross-section open to at least one exhaust space (26). The steam flows in an essentially closed loop cycle, except for a small portion which is extracted and replaced by fresh steam, whereby the steam passes through the heat exchanger (7) and the separate mesh belts as it flows through this cycle.

Abstract: By expansion of the hearth lining when a blast furnace is lit, the tuyeres fixed to the furnace casing are displaced and rotated about the fixed point. The displacements impair the furnace operation and steam escaping from damaged cooling devices destroys the tuyeres. The novel lining is intended to prevent relative movements of the tuyeres and to screen the lining from the tuyeres. Plate-shaped compressible inserts (7), consisting of a plurality of alternating layers of laminated graphite (8) and metal sheets (9), are arranged in the lining in contact with the tuyeres. The inserts are enveloped in copper foils (11) and fixed to the furnace casing. The inserts absorb the thermal expansion of the lining and protect the latter from steam. <IMAGE>

Abstract: Two interacting stacks (26,28) of peripheral overlapping shredding members of disk form are mounted on substantially parallel shafts (30,32) and positioned transversely to the direction of waste material passing through a comminutor casing (10'). The casing opens upstream and downstream side for introducing liquid borne waste to the chamber and for discharging the comminuted waste therefrom after shredding, respectively. The casing is closed off by a pair of imperforate side rails (20'), each side rail (20') is slotted to form a series of inwardly projecting planar fingers (74) having front edges of circular arc form facing the periphery of the rotating cutting element disks (52,54) and having a radius larger than the radius of the disks (52, 54) and being spaced slightly therefrom. The array of fingers (74) extend over the complete height of the stack (26,28) shredding members. This facilitates greater flow of the liquid through the comminution chamber via slots between the fingers (74) carrying fine solids to enhance comminution.

The thickness may be stepwise variable. The layer may be produced by localised melting of the metal of the component, e.g. my laser, electron beam or microplasma.  The roughness may be produced by immersing the component in a medium which reacts with the metal when it is melted.
