摘要： A plant and method for the manufacture of cementitious products, viz. cast concrete roof tiles (T), the plant comprising a mixing station (2) where the constituents of a cementitious composition, less an air entraining agent, are admixed under atmospheric pressure and further mixed under a partial vacuum of 200 to 340 mBar after the addition of an air entraining agent, the plant also comprising a molding station (4) where the tiles (T) are cast in a gang-mold (6) before being cured in a conventional autoclave for up to 10 hours at 45 degrees C. The cured concrete roof tiles (T) are de-molded after curing and conveyed to a surface preparation zone (12) where a primer coat of a water based epoxy and a surface coating of a water based emulsion paint are applied to at least an upper surface in use of the cast concrete roof tiles (T). The admixed cementitious composition has a Ford Cup flow of between 40 and 60 seconds and a slump test of between 180 and 220 mm. In an alternative method, instead of applying a primer coat, the upper surfaces, in use, of the roof tiles T are subjected to abrasion by grit-blasting to remove a thin layer from the upper surfaces thereby facilitating the subsequent application thereto of a surface coating.

摘要： The object of the invention is a method for manufacturing concrete elements, in which method backing plates are transferred on a transferring device (1) to a conveyor (2), along which the backing plates are being moved, concrete is continuously fed by a feeding device (3) onto a backing plate in a compacting machine (4) which is situated near the said feeding device, fresh concrete is pressed into a desired shape in a compacting machine (4) and cut by a cutting device (5, 6) into desired sizes of concrete elements. With the present methods and equipment, it is not possible to manufacture sufficiently strong and variably shaped elements. In the method, according to the invention, reinforcing material is fed to the compacting machine from a reinforcing device (7) which is situated before the concrete feeding device (3).

摘要： The reinforcement ribs on the underside of a concrete roofing tile (2) are formed during the manufacture thereof by directing mortar into recesses (19) in a pallet (P) on which the tile is made, compaction means (18) in the form of multi-tined wheels (18a, 18b) being provided to compact the mortar in said recesses (19) and thereafter providing a secondary layer (46) of mortar over the compacted reinforcement ribs to complete the tile in a conventional manner. A tile provided by the invention comprises reinforcement ribs which are compacted to the same degree as the remainder of the tile thereby ensuring that the finished product, when cured, has a uniform strength or substantially so.

摘要： Hardmetal lamina (15) are cut, by a process known as electrical discharge machining, from a block of hardmetal (10) using a wire electrode (12). The laminae so formed may then be attached by adhesive or epoxy resin to a suitable base (16) in order to form a hard metal surfaced tool. Provision is made for preventing this hardmetal from shearing from its mounting, and also to remove any heat generated within the hardmetal. Reference is made especially to using the above construction for a 'slipper' within a tile producing machine. The word 'hardmetal' is used to denote powdered carbides of the transition metals, cemented into solid masses by a matrix of a metal of a lower melting point.
摘要翻译：通过称为放电加工的工艺，使用线电极（12）从硬质合金块（10）切割硬质合金薄片（15）。然后可以通过粘合剂或环氧树脂将如此形成的薄片附着到合适的基底（16）上，以形成硬质金属表面工具。规定防止这种硬质合金从其支架上剪切，并除去硬质合金内产生的热量。特别是在瓷砖生产机器中使用上述结构用于'拖鞋'。 “硬质合金”这个词用来表示过渡金属的碳化物粉末，通过熔点较低的金属基体凝固成固体。
