Title: Electro chemical machining of fuel valves - inlet chamber of fuel injection valve is recessed using profiled electrode
Inventor: MAI BERNHARD
IPC: F02M61/16
Filed: 1973-11-22
Abstract: The supply valve for a fuel injection system utilises a needle valve that moves vertically and which provides a seal against a conical surface. Output orifices from a central bore supply fuel to the injection system. In order to provide fuel flow to the needle valve with a minimum restriction, an inlet chamber is of larger diameter than the guide bore for the movable needle. The size of the valve is small and difficulty is experienced in machining the recessed chamber using conventional methods. An electrochemical machining process uses a profiled electrode inserted through the main bore and is rotated. Current flowing between the electrode and a suitable electrolyte provides an efficient metal removal process.

Title: Coking coal preheating system - using waste heat from dry coke quenching antechamber and chamber with steam jackets
Inventor: SCHAEFER HUGO DR ING
IPC: C10B57/10
Filed: 1974-07-24
Abstract: In a dry coke quenching system, the inlet part of the coke cooling chamber is designed as a steam boiler and/or as a steam superheater in which the hot coke releases its heat to the walls of a steam jacket. The cooling chambers or a part of it is also equipped with a steam jacket. The recovered waste heat is used to preheat the coking coal to 150-250 degrees C. This prevents coke heat from disturbing the environment and recycles it in the process. Expensive refractory linings with their rapid wear by the hot coke, causing downtimes are saved. The CO content in the cooling chamber is lower thus reducing the risk of explosions.
