Abstract: A first acceleration reference value is continuously determined by a nonlinear distance control. In parallel thereto, a second acceleration value is generated by a nonlinear velocity controller. A simple selection criterion that comprises only these two alternative acceleration values engages the second alternative acceleration reference value engagement for run up. The first alternative acceleration reference value initiates the destination braking. The second alternative reference value is used for approaching the destination position. The trip destination and the velocity of the positioning drive can be accommodate inching velocities.

Abstract: This invention relates to thermoplastically deformable branched aliphatic polyamides prepared by the hydrolytic polycondensation of lactams in the presence of small quantities of .alpha.-amino-.epsilon.-caprolactam (ACL) and approximately equivalent quantities of polycarboxylic acids (preferably dicarboxylic acids) and to a process for their preparation which is distinguished by considerably reduced polycondensation times without giving rise to cross-linked products. The process optionally in addition employs a solid phase after-condensation in which rapid further condensation takes place to the products with increased melt viscosity which are branched but are still soluble in m-cresol.

Abstract: A storage canister for process liquid includes a receptacle having a top side formed with two apertures. The receptacle houses two leakage proof pouches of elastic material each having an opening closed by a control valve. An upper part of respective valve housing projects through the aperture and is secured thereto while the lower part of the valve housing within the corresponding pouch extends up to the bottom of the receptacle. The pouches are arranged one above the other between the top cover and the bottom of the receptacle and being extendable to such an extent that their combined volumes correspond approximately to the volume of the receptacle. Preferably, the receptacle has the form of a flat parallel epiped so that a plurality of equal storage canisters are inserted into a drawer of wet processing apparatus and the normally closed control valves are activated by suction or by over-pressure from suction or pressure devices in the processing apparatus.

Abstract: A rod-shaped tension member formed of fiber reinforced composite material is utilized as an anchoring rod in foundation and mining construction, or as a reinforcing member in concrete and prestressed concrete construction. At least, in an axially extending region where it is to receive an anchoring member, such as a rod, the tension member has a continuous helical thread formed of alternating ribs and recesses. The anchoring member has a corresponding thread so that it can be screwed onto the tension member thread. An intermediate layer is provided between the threaded regions of the tension member and the anchoring nut, and is formed of a material affording large plastic deformation relative to the tension member when slight stress increases occur at overload conditions.

Abstract: A full mold casting process in which a complete, positive model made of a thermally decomposable material is placed in a molding box and filled with sand; the sand is hardened by tamping it in. Casting metal is poured on the thermally decomposable model and the model is decomposed by the casting heat. In order to fill up the cavities of the model and mold moldings with crucial cavities, reliably with the molding sand, the sand is subjected to either a positive or negative pressure differential during the sand-filling phase to enclose and fill the model. The filling and hardening of the sand is further assisted through the fact that simultaneous vibration of the molding box is carried out while the sand is subjected to pressure differential.
