Abstract: The invention relates to a mixing and conveying system for dry mortar materials. The dry mortar materials can be obtained from a storage silo (1) through an openable closure panel (3). A pipe (17), in which a drivable screw conveyor (4) is mounted, is arranged under the closure panel (3). The pipe (17) leads into a mixing and buffer container (18), in which a coil (20) is rotatably mounted on a central axis (19). The mixing and buffer container (18) has a volume which equals at least 1.5-times the minute capacity of the pump-screw conveyor (14). It is thus ensured that the dry mortar material is mixed therein with the added water for at least 90 seconds or longer. The mixing and buffer container (18) leads into a pipe (15) at the bottom having a pump-screw conveyor (14) which conveys the mixed mortar into a hose (5). The pump-screw conveyor (14) can be allowed to run backward. The coil (20) runs continually such that the mortar is constantly agitated to prevent setting.

Abstract: Anchoring system is appropriate for solid rock and concrete (2) and any firm bearing system. The anchor rod (4) of for example a threaded bar out of a shape memory alloy (SMA) is held in the armature bore (3) with a filling compound (5) as anchoring means. For filling the achoring bore (3) between anchor rod (4) and wall of the armature bore (3) a heat resistant filling compound (5) of a polymer connection on a two-component-basis or such on a cementous basis is used. Then the anchor rod (4) is heated by heat input over its butt that is emerging the filling compound on its austenit phase, which pre tensions the anchor rod (4). Finally, after the cooling of the filling compound (5) the anchor rod (4) is cooling of to ambient temperature. A counter bearing board (10) lays on the outer wall (1) around the port of the armature bore (3) and is tensed up with the anchor rod (4).

Abstract: A reinforcing mesh for a reinforced mortar or sprayed mortar layer on an underlayment. The reinforcing mesh includes carbon fibers extending only in a marked direction as a special feature and together with inexpensive stabilising fibers made of glass or polyester which extend in one or more other directions, the reinforcing mesh forms a woven fabric, a scrim or a knitted fabric. The reinforcing mesh can be layed by roughening the surface of the underlayment; applying a leveling layer of cementitious mortar to the roughed surface of the underlayment; fastening the reinforcing mesh by processing the reinforcing mesh into the wet, not yet set leveling layer; and applying a cover layer of the identical cementitious mortar to the wet, not yet set, reinforced leveling layer.

Abstract: A process for machining a blank from all directions with a machine tool, such as a milling machine, involves the machining from all directions being based on a three-dimensional template. In a first step, the three-dimensional form and, if need be, also the surface finish of the three-dimensional template may be automatically measured, and the associated data may be saved. In a second step, a blank may be held by at least one clamping adapter and a first region is brought into its final, ready to use partial form by the machine tool or the milling machine using said data for numerical control. In a third step, the partially machined blank may be held by at least one clamping adapter in the first, finally machined region and the remaining region may be brought into its final, ready to use overall form by the same machine tool or milling machine.

Abstract: The corresponding machine tool or milling machine for carrying out the method described has a milling spindle which is displaceable in three spatial directions and with which the workpiece can be machined in a machining region, the machine tool or milling machine having at least one mounting slide, with which the workpiece, for the first machining step, can be mounted in gripping adapters. Furthermore, the machine tool or milling machine has at least one rocker, with which the partly machined workpiece can be mounted by means of at least one special gripping adapter in the first, finally machined region of the workpiece for the second machining step.

Abstract: The invention relates to a support element, especially for concrete constructions and concrete building components, comprising at least one supporting fiber system embedded in a binder. The aim of the invention is to provide a support element that comprises at least one supporting fiber system embedded in a binder and that is characterized by excellent vapor permeability and at the same time by high stability and good modulus E values. To this end, the binder contains at least one polymer component that has a specific water vapor diffusion resistance value ? of at least 20000, a modulus E of transverse elasticity G of at least 3000 N/mm2 and a tensile strength of at least 10 N/mm2. The binder further contains at least one granular component that extends at least through parts of the supporting fiber system and that forms together with the supporting fiber system, in the cured state of the binder/polymer component, a solid body dispersoid with a water vapor diffusion resistance value ? of not more than 10000.

Abstract: In a method of machining a blank from all directions using at least one machine tool, such as a milling machine, production of the ready-to-use, measured component which is controlled and classified with regard to quality, such as a turbine blade, occurs in as few steps and setups as possible with the use of machine tools and milling machines that as far as possible are of identical design. The blank, in a first machining step, is held by at least one first adapter and a first region is given its final partial shape corresponding to the intended use by a machine tool or milling machine. In a second machining step, the partly machined blank is held by at least one second adapter in the first, finally machined region, and the remaining region is given its final overall shape corresponding to the intended use by a machine tool or milling machine.

The rotating device penetrates the support and the longitudinal axis of the rotating device extends parallel to the longitudinal axis of the digging part.
