Title: Spacer for supporting shuttering elements, and process for erecting pressure-tight, concrete-filled assemblies
Inventor: WERNER BERND
IPC: E04G17/06
Filed: 1984-05-08
Abstract: Spacers which are used to support shuttering elements and remain in the concrete-filled assembly after the concrete-filling process can be approximately sealed against water pressure or pressure of other media only by most complex processes. To eliminate this drawback, a spacer is proposed which, in order to provide mutual support of shuttering elements, is arranged between the latter. To provide a pressure-tight, concrete-filled assembly, a bar-shaped spacing element (12) interacts with a closure body (13) having two differently sized end faces (14, 15) which are located opposite each other in an essentially parallel manner. The smaller end face (14) of said closure body bears on the end face (16, 17) of the spacing element (12). <IMAGE>

Title: Compass knife
IPC: B26B11/00
Filed: 1984-06-28
Abstract: The invention relates to a simplification of the known pocket knife, which is achieved in that a tool steel is half forged into a blade with a straight cutting edge and a knife-cutting edge which is rounded off at the point. The steel is rounded off in a mirror-symmetrical fashion on the handle side, and the point is ground down to the base line at an angle of 110 DEG  and forged into an 8 mm wide screwdriver blade. The blade is magnetised and has a 5 mm hole drilled at the balancing point, and, held by a cord, the magnetised blade rotates in a north-south direction like a compass needle. The 65 mm long protective casing for the blade matches the shape of the blade, consists of reinforced plastic and has a slot on its rounded-off front, so that it can be placed onto the blade even when it has been turned through 180 DEG . The point of the blade which is exposed in this manner can now be used as a carpet knife. The protective casing is pushed over the handle side for use as a pocket knife.

Patent DE-3440603-A1 (DE)
Title: Shaft seal
Inventor: WARSCHKE WERNER
IPC: F04D29/10
Filed: 1984-11-07
Abstract: To avoid machine breakdowns involving a high repair outlay on sealing devices in bearing housings with rotating shafts, for example in centrifugal pumps, the end face at the shaft passage orifice of the machine housing is designed in the form of a spherical sector over the face of the bearing housing matched in diameter to the rotor traveller arranged opposite it, and a co-rotating disk fastened on the shaft together with the rotor traveller is likewise designed parallel and opposite in the form of a spherical sector, but, as a cavity, so arranged that the face of the bearing housing forming a cavity covers it without contact, as it were so as to surround it, with the result that, during operation, a pressure builds up between the faces arranged parallel to one another and prevents fluid from penetrating in the shaft passage orifice. This construction arrangement guarantees a sealing of the shaft passage orifices which needs little repair.

Title: Process for heat treatment of fine granular material
Inventor: ALBERS JUERGEN DIPL ING
IPC: C04B7/43
Filed: 1985-06-04
Abstract: The invention relates to a process for heat treatment of fine granular material, especially of cement raw meal, which is preheated in a multistage cyclone preheater by means of the hot off-gases of a rotary kiln and a precalciner, is precalcined while admixing additional fuel and utilising the rotary-kiln off-gases, is then fed to the rotary kiln for the purpose of completing the calcination and sintering, and is finally cooled in a cooler, precalcination being achieved by passing a part of the material emerging from the penultimate stage of the cyclone preheater into the kiln off-gas line running between the rotary kiln and the cyclone preheater, and the other part being passed into the precalciner which is fed with the additional fuel and preheated air, preferably from the cooler. In order to prevent obstruction of the precalcination taking place in the kiln off-gas line and to preclude unwanted thermal treatment of the material already treated in the precalciner, that part of the material which has been treated in the precalciner is fed to a cyclone, arranged in parallel to the kiln off-gas line, of the last stage of the cyclone preheater, and the material precipitated in this cyclone is fed directly to the inlet chamber of the rotary kiln.
