Patent DE-4222065-A1 (DE)
Inventor: GUGLIELMO AGRADI
IPC: G01K5/32
Filed: 1992-07-04
Abstract: A connection, such as a soldered connection between the ends (4, 5), which can be fitted together, of two tubular piece parts, has interacting sloping surfaces (16, 17) at both ends. The sloping surfaces (16, 17) orientate the inner end (5) in a sliding and centring manner relative to the outer end (4) in such a way that the connecting or soldering surfaces (14, 15) closely adapted to one another find their way into their predetermined congruent position by themselves. At the same time, the connecting or soldering agent (30) can be applied to the joint with the inner end (5) and while being stripped off can be collected there in an annular bead. This results in substantial simplifications in the making of the connection, which is thus suitable for fully automatic mechanised production. <IMAGE>

Title: Disposal of films carrying information by treatment with solvent - comprises removing information layer, followed by disposal or reuse of film
Inventor: AKPINAR AHMET
IPC: B29B17/02
Filed: 1992-07-09
Abstract: In disposal of films used to carry information, to remove the information layer, the film is placed in a container with a solvent, and the treated film is thrown away or used again. The solvent is harmless to man. For vesicular and diazo films, and dry films the solvent dissolves the binder layer between the film support and the layer carrying the information, and contains an organic solvent, esp. acetone or more than 50% (more than 95%) of an alcohol, pref. ethanol. For Ag films, the solvent contains an oxidising agent, esp. more than 4% (more than 30%) of H2O2. The solvent also contains a salt, esp. where the negative acid residue forms with Ag a salt which pptes. from the solvent, esp. Cl. The pref. salt is NaCl, in amt. about half that of the oxidising agent. The salt and the oxidising agent are dissolved in deionised water, and the solvent pref. contains 4% of H2O2, 2% of NaCl and 94% of deionised water. ADVANTAGE - Data, esp. confidential information are removed quickly, and the film can be processed again by personnel without security rating.

Title: Coupling device for pipes
Inventor: MAECKLE RAIMUND
IPC: F16L23/06
Filed: 1993-06-07
Abstract: The invention relates to a coupling device for pipes for the pressure-feed of thick matter, such as concrete. At the mutually facing pipe ends, the coupling device exhibits essentially radially projecting coupling flanges (14, 16), a sealing ring (30) arranged between the coupling flanges, and a clamping mechanism (36) which presses axially against one another the coupling flanges (14, 16) bearing against one another on the end sides. In order to be able to join the coupling flanges (14, 16) together in a positively locking manner before pressing and to centre them with respect to one another and adjust the sealing forces independently of the pressing by the clamping device, the invention proposes that the coupling flanges (14, 16) engage one in the other in each case by an outer connection stub (24) and an inner connection stub (20), projecting axially beyond an annular flange part (18, 22) and that an interspace (32) for receiving the sealing ring (30) is arranged between the inner connection stub (20) and the outer connection stub (24), and that the inner connection stub (20) and/or the outer connection stub (24) can be pressed, with their end surfaces, against the adjacent flange part (18) and (22) respectively of the other coupling flange (14, 16) by the clamping mechanism (36). <IMAGE>

Title: Releasable connecting element
Inventor: SCHULZE LOTHAR DR ING
IPC: E05B17/00
Filed: 1993-08-14
Abstract: The invention relates to a releasable connecting element for the damage-free dismantling of an article, having a locking piece which is guided in a framework and, when the closure is produced, is locked automatically by a locking device. The object of the invention is to provide a connection which can be released easily and reliably either sequentially ("by hand") as well as simultaneously (by the action of a non-directed physical variable). Said connecting element is intended for use with such articles which are intended to be easy to demount or remount since, in this arrangement, the particular wish is for separation without damaging the connecting elements. The object is achieved in that the locking device (2) disconnects the closure both directly by the exertion of a directed force on the locking piece (5) and indirectly with the action of the change in a non-directed physical variable. <IMAGE>
