Title: Method and apparatus for the collection and treatment of liquid manure
Inventor: MANNEBECK BERNHARD
IPC: A01K1/01
Filed: 1981-01-17
Abstract: Liquid manure, especially from pigs, is collected from the animals stabled in a byre under the animal standing plane permeable to liquid manure and is aerated before being discharged from the region of the byre. To improve the byre climate and reduce odour, the liquid manure occurring continuously during the stabling time of the animals is collected in an intermediate collector under the standing plane of the stabled animals, and the quantity of liquid manure collected in the intermediate collector is circulated constantly or at short time intervals in closed forced circulation and, during circulation, is aerated constantly or at short time intervals. The collection of liquid manure in the intermediate collector is limited to a part quantity which corresponds to a small fraction of the total quantity of liquid manure occurring during the stabling time of the animals, and this limited part quantity is kept essentially constant in that a portion is extracted constantly or at short time intervals from the part quantity contained in the intermediate collector and is fed to a main collector which corresponds in terms of quantity to the constant supply of fresh manure.

Title: Connection between two components, in particular housing elements of brake cylinders, and a method for the production of the connection
Inventor: LECHNER ANTON DIPL ING DR
IPC: B60T17/08
Filed: 1981-06-29
Abstract: The invention is implemented in a connection between two components, in particular casing and flange elements of brake cylinders, locking elements or locking pins which can be inserted into slots or grooves in the casing element and in the end or flange element being provided. If the casing element and the flange element are clamped together at the time of assembly, these components can be displaced slightly in such a way relative to the locking elements or locking pins inserted between them, when the clamping force is removed, that the locking elements or locking pins are fixedly secured. The removal of the connecting or locking elements is correspondingly simplified. According to one embodiment, countersunk screws known per se are used and are tightened in such a way relative to the holes in the casing element which receive them, or to the associated threaded holes in an intermediate flange, that flow of the material occurs in the region of the contact area of the screw with the inner wall of the hole in the casing element. This eliminates expensive countersinking by machine in the region of the entry to the hole. Work hardening at the bearing surface of the screw or screw head can furthermore be achieved.
