Title: Device for utilising the heat of the exhaust gas in internal combustion engines
Inventor: PIETZNER PETER
IPC: F01N5/02
Filed: 1983-12-02
Abstract: Device for utilising the heat of the exhaust gas for internal combustion engines. Mounted on each side of the engine, e.g. a V8 cylinder engine, is a water container which is connected to boiling tubes which are mounted spirally around the exhaust manifold or exhaust pipes underneath the water container and in which high-pressure steam can be produced by heating of the water in the said tubes. The steam is passed from the heater into the water container or tank and from there, by virtue of excess pressure, into the two front cylinders, which are no longer supplied with fuel. After the working stroke, the spent steam is cooled in a cooling system and passes back into the water container in the form of water.   In the engine, the functions of the outlet and inlet valves are reversed (the inlet becomes the outlet and the outlet becomes the inlet). The steam is propelled into the combustion chamber of the cylinder by the excess pressure in the water container.

Title: Drum-type mill with internal rotating shovel grinding roller
Inventor: EMMERMANN ELISABETH
IPC: B02C17/18
Filed: 1984-01-13
Abstract: The drum casing which revolves about its own axis at about 300 rpm drives a shovel grinding roller in its interior, preferably of about 0.6 times the drum diameter, constructed such that it can grind the material to be ground and itself feed it again, and such that after grinding it repeatedly throws the material within the drum casing so high that an air stream flowing along the axis can withdraw a first fine fraction and discharge it through the central middle opening, and that the ground material, thrown high, flies in a wide arc onto the free drum wall and thus arrives in front of the grinding discs, where, because of the grain distribution, the thicker, unmilled grain always breaks first, while the ground fine grain remains on the drum wall and is drawn off and discharged from the slot opening.

Patent DE-3411285-A1 (DE)
Title: Reusable, frictionally-locked threaded bolt securing device of a screw connection having a threaded bolt and nut
Inventor: LE THANH-SON DIPL ING
IPC: F16B13/06
Filed: 1984-03-23
Abstract: In the case of screw connections having threaded bolts and nuts, the threaded bolts are connected to the braced part in a frictionally-locked and positively-locked manner by means of thread inserts. In this case, the securing part of the thread insert is pressed firmly onto the thread of the threaded hole of the braced part, over the projection of the threaded bolt, by means of the screw pretensioning force. The higher the screw pretensioning force, the greater is the friction lock between the thread insert and the threaded hole. In this way, the threaded bolt is secured against becoming loose on its own and against becoming lost. The projection on the threaded bolt can either be designed such that there is a self-locking conical connection between it and the thread insert or such that the threaded bolt becomes flexible with respect to the transverse displacement of the nut. The two braced parts can be connected to one another in a positively-locked manner by means of suitable design of the thread insert. As a result of the use of thread inserts, the screw connections are more elastic and hence more secure against settlement. In addition the thread pitches of the threaded hole are loaded more uniformly. The threaded bolt is detachable and the thread insert is always reusable.
