Patent DE-3634733-A1 (DE)
Title: Suction device
Inventor: FREIMUTH FRIEDRICH
IPC: B67D7/04
Filed: 1986-10-11
Abstract: To avoid the occurrence of leaks during the evacuation of sewage containers, a coupling is arranged in the region of the connection. Automatic control ensures that the coupling is automatically closed on termination of the suction process. Sealing in the coupling body can be carried out by means of pistons and/or elastic moulded parts. The coupling region can be rinsed out during and after closing. The residual sewage which has penetrated the coupling region during suction and/or flushed-out residues which have penetrated the coupling region during closing are sucked out at the same time. Designing the coupling in this way makes it possible for the suction process to be carried out in a drip-free and odour-free manner, even when the coupling is being mounted and removed. A hose guide has been provided to permit handling of the coupling, removal and mounting of the coupling being facilitated both as regards the amount of space required and the flexibility of the hose.   The attached drawing illustrates one embodiment. <IMAGE>

Title: Method of constructing a tunnel under a stretch of water
IPC: E21D9/06
Filed: 1987-01-27
Abstract: In the construction of a tunnel under a stretch of water, e.g. a river course (1), first of all the part (5a) of the tunnel tube (5) which is located in the region of the river (6) is produced by an open method of construction, e.g. as an underwater tunnel, in which individual prefabricated sections of the tunnel tube are floated into position and sunk. Then the parts (5b, 5c) of the tunnel tube (5) which lie in the bank area are driven from the land by a closed method of construction, e.g. by shield driving by means of a driving shield (15). The driving-side ends of these parts (5b, 5c) are directly attached in a sealed manner to the end (17), corresponding in each case to these ends in inner cross-section, of the already constructed part (5a) of the tunnel tube (5). The end part (17) of the centre piece (5a) of the tunnel tube (5) can be of socket-like design, the driving shield (15) being moved into this socket. Owing to the fact that the inner cross-sections of the tunnel-tube parts constructed according to different methods are designed in a manner corresponding to one another, i.e. the ventilation ducts are also arranged at corresponding points of the cross-section, the different parts of the tunnel tube can be directly attached to one another without expensive transition structures. <IMAGE>
Patent DE-3718016-A1 (DE)
Title: Process for mechanical-chemical-thermal desulphurisation of bituminous coal
Inventor: WISSING WILHELM
IPC: C01B17/16
Filed: 1987-05-27
Abstract: For the separation of free, organically bound and inorganically bound sulphur from bituminous coal, coal grinding down to pulverised coal is indispensable because, in doing this, hard pyrite is also ground down and separated out from the coal-grinding plant together with the usual foreign materials wood, small iron parts and the like. The coal grinding is also necessary because the boundary layer of ground solid bodies has properties different from those of lump coal in the adjacent range of volume. The mean energy of the molecules in the surface layer, as surface energy, corner energy and edge energy, is different, according to crystal physics and crystal chemistry, from that of many superposed space groups of the lump coal. The surface area, enlarged many times, allows increased adsorption of paraffin chains on sulphur in the coal. Free sulphur reacts at 170@C with paraffin, with very good yield:  CnH2n+2+(n+1)S = nC+(n+1)H2S. In the case of organically bound sulphur, an exchange adsorption takes place in which the reaction occurs according to the equation:  AY+X = AX+Y in the same way as in other double decompositions in chemistry. The enthalpies of formation of sulphur compounds are extremely low; the reactions proceed towards the right. Inorganic grain material is precipitated in the pneumatic classifier.

Patent DE-3722311-A1 (DE)
Title: Vessel forceps
Inventor: BRAUN BERND DIPL CHEM DR MED
IPC: A61B17/00
Filed: 1987-07-07
Abstract: The vessel forceps for clamping of blood vessels has three clamping jaws (14, 15, 16) two of which are arranged rigidly next to one another with a small lateral spacing. The third clamping jaw (14) presses the blood vessel against each of the other two clamping jaws (15, 16), so that the mechanical pressure force is distributed while, on the other hand, large contact angles are avoided. All three clamping jaws (14, 15, 16) are provided with longitudinal grooves in order to prevent slipping. Concave grip plates (21, 22) permit reliable, simple handling. The vessel forceps with the crossing clamping legs (10, 11) has small dimensions and is lightweight. The essential advantage resides in the fact that traumatisation is prevented by the interaction of two pressure points and a small amount of wrap. <IMAGE>

Title: Dialling pause control in telephone stations with route selection
Inventor: HARTMANN KARL-DIETER
IPC: H04M1/27485
Filed: 1989-03-16
Abstract: The invention relates to a method for dialling pause control with route selection for outgoing exchange connections in telephone stations with an exchange code memory, name keys, a telephone number memory and a preferred route, the preferred route being automatically selected following a second dialling pause of more than 1 sec and the individual criteria in the exchange code memory and telephone number memory being compared with one another for selecting the exchange line. On activation or read-out of the flash key criterion in order to access the exchange code memory, a first longer dialling pause is always inserted and, following comparison and matching of the exchange line code, a second longer dialling pause is inserted which automatically activates the preferred route. This is intended to be prevented. To achieve the object, a flash key criterion is attached in front of each exchange code in the exchange code memory and the first comparison is then a flash key criterion comparison which produces a dialling pause of only 800 ms. In the event of a match in the route-determining part of the exchange code, the first longer pause is then inserted and there is therefore no changeover to the preferred route. For use in digital microprocessor-controlled telephone stations.
