Patent DE-3100398-A1 (DE)
Title: Pressure-medium cylinder
Inventor: MUELLER ROLF DIPL ING
IPC: F15B15/10
Filed: 1981-01-09
Abstract: The pressure-medium cylinder has a piston which is guided on a rod. Disc-shaped end parts are fastened to the two ends of the rod, and from each of these end parts a telescoping element leads to the piston, to which it is firmly connected. This results in working spaces between each end part and the piston. The working spaces can be acted upon or relieved via a passage in the end part. Fastened to the outer periphery of the piston is a driver which transmits the movement of the piston to an implement. It is advantageous that from the piston to the driver no penetration of the working space is necessary, which - as known - has to be sealed off, which is very problematic. The proposed pressure-medium cylinder is consequently very simple and trouble-free. It is especially suitable as a pneumatic cylinder for lower to medium pressures, e.g. 20 bar.

Abstract: This bucket-wheel machine equipped with a slewing bucket-wheel boom has devices with which the speed (nS) of the bucket-wheel boom (1 or n13) of the slewing drive (13) can be limited as a function of the speed (nR) of the bucket wheel (5 or n6) of the bucket-wheel drive (6) to a value at which the superstructure (1, 3) of the bucket-wheel machine - while utilising the rated power of the bucket-wheel drive (6) and the slewing drive (13) - is loaded essentially uniformly in operation up to the permissible static loading capacity by the side force acting on the bucket wheel (5). To this end, the regulating or control unit (20) of the slewing drive (13) is connected via a computer (17) to the speed transducer (16) of the bucket-wheel drive (6). The "speed" (nS), limited by the computer (17), of the bucket-wheel boom (1) essentially corresponds to a value proportional to the square of the speed (nR) of the bucket wheel (5). For improved utilisation of the computer (17), the speed transducer (16) of the bucket-wheel drive (6) is in addition connected via the computer (17) to one current-limiting unit (18 or 21) each for the bucket-wheel drive (6) and the slewing drive (13) and to one regulating or control unit (19 or 22) each for safety devices (8 and 14) of the bucket-wheel drive and slewing drive respectively. <IMAGE>

Title: Wall which is in the form of a grid and comprises prefabricated compound units
Inventor: RAUSCH PETER ING
IPC: E04H17/14
Filed: 1981-06-01
Abstract: In the case of a wall which is in the form of a grid and comprises prefabricated compound units, in particular prefabricated concrete compound units, the aim is to standardise and to simplify the elements, which are necessary for building the wall, and the design for a very wide range of functions of walls in the form of grids, in order to make possible a cost-effective production of the prefabricated compound units, on the one hand, and a problem-free erection of the walls, on the other hand. For this purpose, the invention proposes to arrange cross-sectionally U-shaped or trough-shaped beams in an open stretcher masonry bond. Near the ends, the beams are provided with holes passing through the trough bases. The beams are mounted one upon the other, with holes one above the other, and are connected by means of bars pushed through the holes. In order to increase the stability, these bars may also be screwed into threaded sleeves, seated in foundation blocks, and clamped by means of screwed-on nuts which act on the uppermost beams in each case via pressure-exerting plates. The wall built in this manner can be used for many purposes, in particular for enclosing and fencing in, as a parapet, as a snow fence or, in an embodiment with a closed rear surface, as a noise-insulating wall.
