IPC: B28B3/02
Filed: 1982-06-18
Abstract: The invention relates to the process technology for manufacturing construction materials. The process for manufacturing concrete slabs is characterised by the compression of a prepared plastic mixture, which is in the stage of forming a coagulating structure, under processing conditions which permit the removal of the excess moisture whilst intensively pressing it through the mixture. The equipment for carrying out the process according to the invention contains a mixture preparing unit (1) for preparing a plastic mixture (15), which is then transported by a conveyor (2) to a shaping assembly (9) of the press (4). A slide block (6) is mounted on the frame (5) of the press (4), to which slide block is attached a press ram (7), which is enclosed by a frame (8). The frame (8) is connected with the slide block (6) by means of a displacing mechanism (10) for displacing the frame (8) with respect to the press ram (7). The displacing mechanism (10) effects a non-positive connection of the shaping assembly (9) with a bedplate (12) mounted on the frame (5). This bedplate (12) has a filter element (13) mounted on its surface, which is connected to a collection and draining means for excess moisture and comes into contact with the belt (14) of the conveyor (2).

Patent DE-3224989-A1 (DE)
Title: Shears for cutting strand-shaped material
Inventor: WOLTER ECKHARD
IPC: B23D29/02
Filed: 1982-07-03
Abstract: Mounted on a holding lever (1) in the bearing pin (2) is a pivoting lever (3), the pivoting of which causes, via the pawl (7, 8), the pinion (6) to pivot the movable cutter (22) towards the fixed cutter (21) by means of the toothed guide segment (24) fastened to said movable cutter. Both shearing cutters have an annular cutting edge (33) for an annular cutting opening (34) closed on all sides and a jaw cutting edge (31) for shearing jaws (32) open to the outside. Transverse forces acting between the edges (31 and 33) in such a manner as to spread them apart are taken up by grinding faces (35, 36), thus producing a clean cut, especially in the annular cutting opening (34). In addition, the fixed cutter (21) is supported on the inside of the guide segment (24). The radial forces exerted by the bearing pin (2) are therefore taken up over a short distance by the fastening screws (51) for the fixed cutter (21). With the aid of the shearing jaws, it is possible to work in tight spaces such as switch boxes, and it is possible to cut, for example, steel cables, whereas the annular cutting edge is used for the cleanest possible cuts, for fine-cord cables for instance. <IMAGE>

Title: Building unit for mounting working platforms on scaffolding towers or the like
Inventor: HOPPE LOTHAR
IPC: E04G1/15
Filed: 1983-02-02
Abstract: The invention relates to the erecting of working scaffolding which consists of scaffolding towers and working platforms mounted thereon.   In known working scaffolding of this type, the span of the working platforms is limited. The object of the invention is to achieve greater spans for the working platforms and hence a greater useful working surface without increasing the material requirement and production effort for the scaffolding towers. The object was therefore to connect the working platform to the scaffolding towers in such a manner that cantilevering of the working platform is possible and, when a plurality of working platforms are arranged in series, workers can walk from one platform to the next. This object is achieved by means of a set of building elements which consists of a bearing latch which can be positioned by means of flanged sockets on the uprights of the scaffolding tower and is provided with adjusting cams and connecting plates, an associated supplementary latch provided with a head plate and flanged socket, and two bearing cross-pieces which can be clamped onto the lower flanges of the working platform and are provided with clamping devices and pressure plates.
