Patent DE-3727202-A1 (DE)
Title: Method of constructing sealing trench walls
Inventor: BORBERG ECKHARDT DIPL ING
IPC: E02D19/18
Filed: 1987-08-14
Abstract: In known methods, sealing sheets are drawn into a slowly hardening supporting suspension after the excavation of the soil trenches. The margins of adjacent sheet sections are threaded into hollow bodies which are pumped empty after the sheets are drawn in, whereupon the sheet margins are cleaned and welded to one another. The hollow bodies are then removed from the soil trench. This method requires hollow bodies of quite complicated design and is also complicated in application, since the sheet margins always have to be cleaned and then welded to one another. The method according to the invention provides for the hollow bodies themselves to be used as sealing elements by virtue of the fact that, after a sheet section is drawn in, the suspension which has penetrated into the slit hollow body is displaced by a sealing mass fed into the hollow body and surrounding the relevant sheet edges. The hollow body is left in the soil trench. The method is used for constructing sealing trench walls for sealing landfill sites or the like against groundwater and seepage loss water. <IMAGE>
Patent DE-3734303-A1 (DE)
Title: Set for processing root canals in a tooth, and cutter therefor
Inventor: GRABOSCH REINHOLD DR
IPC: A61C5/02
Filed: 1987-10-10
Abstract: In endodontology, location of the entrance of the particular root canal to be processed is difficult in teeth having several root canals, because the entrances of the root canals lie closely adjacent and they can be looked into only via a mirror, not directly. A new measure is intended to facilitate location of the entrances of the root canals. A set comprises cutter(s), nerve broaches and sleeves which preferably have different colours. The particular cutter is provided with continuous bores in the shaft and the cutter head which is coupled to the shaft via a helical spring. For processing of the root canals they are initially exposed and their entrances are marked by the sleeves inserted in the ends of the root canals on the side of the dental lumina. The tooth is then built up with a restoring filling up to the occlusal plane and with fixation of the sleeves. The individual entrances of the root canals are now clearly marked. A nerve broach with or without a very thin shaft is inserted into the corresponding sleeve and the associated root canal. The cutter is pushed onto the nerve broach and can be used without problems in the root canal under guidance by the needle.   <IMAGE>

Title: Method for producing line codes by printing on any kind of material, in particular on textiles, and device for carrying out the method
Inventor: HAAKERT MANFRED
IPC: B41M3/00
Filed: 1987-11-15
Abstract: The invention relates to a method for producing line codes by printing on any kind of material, in particular on textiles, and a device for carrying out the method. In this case, it is important that the production of any desired line code on any desired material is possible without a printing pattern and without exchanging the printing device with full-surface printing of the elements of the respective line code. By means of electronic control of the printing stamp of the printing device required for printing the basic elements and/or printing surface parts of the elements of the line code to be produced, it is possible, after automatic setting of the printing device to the raster setting of the line code, to produce the elements of the line code with one printing impression or with printing impressions following directly on from one another with appropriate horizontal displacement of the printing device.
Patent DE-3740418-A1 (DE)
Inventor: WOLF JOACHIM
IPC: B01D35/30
Filed: 1987-11-28
Abstract: A filter apparatus is equipped with easily releasable coupling ends (28) of the inlet and outlet connection pieces (27) respectively, and the top wall (11) carrying the inlet and outlet connection pieces is connected unreleasably to the adjoining peripheral wall of the filter housing. For maintenance or cleaning, the filter apparatus is exchanged as a self-contained unit. Since the filter housing itself is not separable in operational terms and there are therefore no sensitive separable seals between housing parts, the housing cross-section can be of any form and therefore especially cuboid for the most effective possible utilization of space.

Patent DE-3831952-A1 (DE)
Title: Arrangement in a torpedo search head
Inventor: BOEHM CHRISTIAN
IPC: F41G7/22
Filed: 1988-09-21
Abstract: In a torpedo search head, usually a sonar search arrangement is present in order to align the torpedo with the target in the end phase of the torpedo run. In order to prevent the fixing of the target from being falsified by an acoustic decoy which is released from the actual target, according to the invention an arrangement for determining the magnetic field is also provided in the torpedo search head. In the vicinity of the target the magnetic field of the earth is substantially disturbed, in particular substantially more strongly than by the acoustic decoy so that the approximate direction of the true target can thus be detected and the effect of the acoustic decoy can be eliminated. Additionally, there is also provision for the magnetic alternating field of the target to be evaluated. <IMAGE>

Title: Solar thermal power station (plant) using environmental heat
Inventor: TREPTOW ROLAND
IPC: F03G6/00
Filed: 1988-10-07
Abstract: In order to reduce the load on the environment, to lower costs and to lessen direct operational risks, this "energy carrier" in the form of a Rankine (thermal) steam power process (cycle) of a material which has a relatively low boiling point, such as the incombustible CO2 (circulating working agent), makes use of the self-regenerating continuity of the atmospheric temperature gradient due to the day/night rhythm of the sun (rotation of the earth), on the basis of which even in the case of relatively low temperature differences it is possible to convert thermal energy of "infinitely" large quantities, in particular in the case of exploiting the periodically stationary temperature gradient between in each case two agents (preferably atmosphere and ground; materials of truly infinitely large thermal (heat) capacity C = m . c = dQ/dT) to be found in nature. <IMAGE>

Title: Method for the production of tubular components
Inventor: KUHN RAINER DIPL ING
IPC: B21D26/02
Filed: 1988-12-05
Abstract: The invention relates to a method for the production of tubular components in which, starting from a metal sheet, a tube is formed and the two ends are welded together and the tube obtained subjected to an expansion process. The object on which the invention is based is to provide a method for the production of tubular components by means of which high-quality tubular components, for baking tubes for example, can be produced economically and in an operationally reliable manner. The invention consists essentially in that, before the expansion process, the tube is mechanically pre-expanded and in that both ends of the pre-expanded tube are sealed, after which it is subjected to a hydroforming expansion process. The advantages obtained consist above all in that, when the method is employed, there is a considerable saving in materials for the body to be produced and that there is virtually no waste produced in the course of the production process. In addition, tooling costs for conversion to different types of tubular components are low. There is also no problem in using sheets of very different quality, e.g. normal deep-drawing steel and austenitic and ferritic stainless steel. Different thicknesses of sheet can also be processed without problems.
Patent DE-3841979-A1 (DE)
Inventor: OSTWALD JUERGEN DR
IPC: G02B5/00
Filed: 1988-12-14
Abstract: A light trap free from backscattering for linearly polarized light comprises a polygonal housing, the side faces of which are parallel to an imaginary axis passing through the centre of symmetry and are arranged at constant angles to each other and to the input surface. Each side face is provided with grey filters with shiny smooth surfaces. Light-reflecting masks are arranged behind the grey filters in the path of the transmitted beam. The light entering the light trap strikes the first grey filter at the Brewster angle, and is largely absorbed by the first grey filter. Some of the incident light is reflected at the surface and the next face of the grey filter and at the light-reflecting surface of the mask to the next grey filter, which it also strikes at the Brewster angle. The serial connection of several grey filters results in a light trap virtually free of backscattering.
