Patent DE-4021931-A1 (DE)
Title: Heat-insulated piston-engine - has combustion piston with hollow ceramic crown working inside annular one
Inventor: TAUSEND ERICH
IPC: F02B41/06
Filed: 1990-07-10
Abstract: The piston engine is extensively heat-insulated, having connected chamber in which two pistons work. A mixture of fuel and air is formed and compressed in the first chamber (R), which has cooled walls, and is transferred in the compressed state to the second (B), whose walls are not cooled, inside which combustion takes place. The walls of the second chamber, and the piston working with them are heat-insulated by ceramic material. Charge-changing takes place in the first chamber, using a slot system controlled by the piston. The pistons consist of an outer annular one (KR) and a concentric combustion piston (KB) working inside it. The annular piston has cylindrical liners for the sealing ring and guidance of the inner one. The latter has a thin-walled hollow ceramic crown, whose height is such that the swept volume of this piston is outside that of the annular one in the axial direction. USE/ADVANTAGE - IC engine runs on gaseous or vaporising fuelds and ensures complete combustion.
Patent DE-4027125-A1 (DE)
Inventor: IRPS HARTWIG DR ING
IPC: A01K1/01
Filed: 1990-08-28
Abstract: The cleaning of agricultural stables is to be carried out in a manner treating the floor carefully by means of one or more sliding plates (figure) mounted on a travelling frame (a). An electrical drive (d) attached to the travelling frame and having a current supply from outside the region of the animals makes it possible to travel over the predetermined runway. In semi-automatic or fully automatic operation, the pit cleaner runs under or through animal partitions (n) adapted to the cleaner. During the return also, it is to be possible, if the farmer so desires, to remove dung which has occurred in the meantime. The use of the self-propelled pit cleaner is intended to improve low-straw or strawless stable systems in conjunction with the appropriate floor design. Operating reliability is to be increased in comparison with existing installations. The travelling frame (a) of the pit cleaner will, as far as possible, not exceed a constructional height of ten to twenty centimetres. A low running speed of up to approximately three metres per minute will have no adverse effect on the behaviour of the animals. <IMAGE>

Patent DE-4141020-A1 (DE)
Inventor: HEINRICH PETER DIPL ING
IPC: C23C4/134
Filed: 1991-12-12
Abstract: The invention relates to a process for coating a surface by means of a thermal spray method, in which a spray jet of hot carrier gas and molten material particles is directed at the surface in question and at the same time cooling is effected adjacent to the spray jet by means of a cooling jet which consists of substantial proportions of carbon dioxide and contains cold gas and snow particles. Hitherto, such a process was carried out based on liquid carbon dioxide, in order to ensure that a useful cooling jet with correspondingly high snow particle fractions is obtained. According to the invention, the carbon dioxide fraction in the cooling jet is obtained from gaseous carbon dioxide which is at a pressure of at least 45 bar, specifically by the carbon dioxide gas first being expanded, via a slit nozzle or another slit-like orifice, into an expansion volume which is disposed about said expansion slit and is largely enclosed with respect to the environment, and starting from this expansion volume and its outlet orifice the cooling jet is formed and is directed at the region to be cooled. <IMAGE>
