摘要： Device (1) for the placement of separators between products of concrete extruding machines, applicable for installation in an extruding, molding, profiling, slipformer or flowformer machine (2) of parts (3) of concrete, the machine (2) comprising a guillotine (5) to cut the concrete outflow and form said parts (3), the respective ends of which, i.e. rear and front end, are kept free of deformations by placing between them a separating caisson (6), wherein the device (1) comprises securing and displacing means (10, 11, 12, 13) to carry out the placement and extraction of said separating caisson (6), the caisson (6) remaining placed in an intermediate gap (7) between the rear and front end of consecutive formed parts (3) for a time period necessary to avoid deformation of said ends while the machine (2) goes on extruding. Preferably the device (1) comprises a carriage (10) adapted to slide along a horizontal guideway (11) that is incorporated into the machine (2), on its outlet (2a) of the concrete flow, together with the cutting guillotine (5) provided on said outlet (2a), securing means (12) to secure the separating caisson (6) and transfer it with the carriage (10) along the guideway (11) and vertical displacement means (13) for lifting and lowering the separating caisson (6), to lower the caisson (6) so as to deposit it in the gap (7) present after cutting of the part (3) of concrete by the guillotine (5) and to lift it anew later on.

摘要： A method used in a process of forming a ceramic product, the method comprising:
producing a ceramic forming mixture in the form of a slurry;
causing the slurry to foam;
extruding the foamed slurry, by passing the foamed slurry under pressure through a feed pipe into a die unit to produce a plurality of relatively fine lengths of extruded material;
firing the extruded material so as to partially sinter the extruded material by controlling, a thickness of material passing through a kiln, a speed of travel through the kiln, and a peak firing temperature in the kiln; and
pressing the partially sintered extruded material together, forming the partially sintered extruded material into a required shape for a product for subsequent firing to form the ceramic product.-
