Title: Device for connecting two pipes
Inventor: SCHNALLE WILLY
IPC: F16L21/06
Filed: 1982-12-08
Abstract: The invention relates to a device for connecting two pipes, in order to produce pipes of a given pattern, especially in aircraft construction, using a pipe connecting piece which is screwed into the two pipe ends to be connected. The device consists of two half shells which have holes directed tangentially, by means of which the two half shells can be screwed together. Furthermore, threaded holes are incorporated in each half shell, into which holes beading screws are inserted. The device, which is fitted to the pipe connecting point, is now used to the effect that, with the aid of the beading screws, a bead is incorporated into the pipe material beneath it, which bead propagates onto a connecting collar. In consequence, an immovable attachment is created between the pipe and the pipe connecting piece.   <IMAGE>

Patent DE-3311203-A1 (DE)
Title: Method for reproducing a reference position
Inventor: BURKHARDT HORST DR
IPC: G01D5/36
Filed: 1983-03-26
Abstract: In this method, a reference position can be reproduced at any time independently of the instantaneous position of the objects (A and B) movable relative to one another. After decoupling of the objects (A or B) to be measured, either the scanning plate (8) or the measuring graduation (4) of a measuring device is pivoted until a reference mark (Ri) is overrun. The scanning of the overrun reference mark (Ri) generates in the counter (Z) a signal with which the counter (Z) is set to the value "zero" or to another prescribed value. Starting from there until the return to the instantaneous starting position, the grating lines of the graduation (4) are counted, so that subsequently the difference is known with respect to the reference mark (Ri) which represents the reference position. The measurement position is reproduced by return to the instantaneous starting position, and the operations can be continued. <IMAGE>

Title: Method of producing a foundation
Inventor: WACKENHUT ERNST
IPC: E02D27/44
Filed: 1984-05-03
Abstract: The invention relates to a method of producing a foundation, in particular for heavy machines, with excavation of the foundation pit and subsequent concreting with the use of wall formwork. Here, in order to dispense with the measures for securing the foundation pit, the excavation is effected step-by-step first of all to a small depth, whereupon the wall formwork is erected, and only then is the first step repeated in one or more further steps. Consequently, not only is the object achieved, but the total production costs are also reduced and the time taken is considerably shortened. This method is used in particular in the case of foundation bodies of square or rectangular shape with side lengths of 6-7 m. The conventional protection by driving sheet pile walls is dispensed with by the method according to the invention. In this way, the noise nuisance is also reduced and cracks are avoided.
