Title: Fifth-wheel coupling
Inventor: JAKOB LOTHAR
IPC: B62D53/08
Filed: 1986-08-06
Abstract: The invention relates to a fifth-wheel coupling with a coupling plate which has an insertion slot through which a kingpin can be inserted. The fifth-wheel coupling furthermore has a first and a second fastening part which surround a kingpin. In this arrangement, the kingpin (5) rests snugly in the first fastening part. Since the driving operation causes high wear on the kingpin or on the fastening part readjustment is often necessary in order to compensate for a clearance produced by the wear between kingpin and fastening part. To this end, an eccentric insert is provided which is arranged around the pivot of one fastening part. The insert has a lever-shaped extension (9a), with the aid of which the insert (9) can be rotated. If the lever (9a) is rotated the fastening part moves and entrains the second fastening part at the point of mutual engagement. This adjustment makes it possible for the kingpin (5) to be brought into close contact with the first fastening part so that the clearance produced by wear is compensated for. The proposed arrangement makes precise adjustment or readjustment possible and is easily accessible from the outside. By virtue of the simple construction expenditure on servicing and operation are insignificant. <IMAGE>

Title: Process and equipment for the manufacture of cement from moist raw materials
Inventor: KUNZE OSWALD
IPC: C04B7/40
Filed: 1986-11-28
Abstract: In the manufacture of cement from moist raw materials, these are, according to known processes, fed directly to a wet rotary kiln immediately after prior wet grinding and fired therein to give clinker. In this case, all the slurry water must be evaporated, which involves a high consumption of thermal energy. In another process, a part of the raw materials is in turn prepared in the dry state, and the remaining part is subjected to wet grinding. After prior mixing and granulation, both part quantities are then fed to the rotary kiln. In this case, the relatively high equipment cost and the increased consumption of thermal energy are disadvantageous. According to the invention, however, these disadvantages are avoided by mixing the moist raw materials, before they are preheated and dried, with dry raw materials of substantially the same composition. <IMAGE>
