Patent DE-2034376-A1 (DE)
Title: Vapour scouring metal pieces
IPC: C23G5/04
Filed: 1970-07-10
Abstract: The metal pieces are introduced into a vapour area including a volatile solvent.

Title: Road tanker filter for pump feed - can be inactivated for gravity feed by shifting or bypassing
Inventor: WEBER PETER
IPC: F16L55/24
Filed: 1973-02-16
Abstract: A filter upstream of the pump must be provided in the line for petrol or fuel oil from a road tanker to an underground tank, to prevent contamination of the pump. When the pump is not in use and gravity is used as prime mover for the petrol flow, the filter element can be made inoperative.

Patent DE-2326172-A1 (DE)
Title: Gas sterilizer door/piercing interlock - using spring-loaded piston actuators with one sided vacuum application
Inventor: KRICK GERD DR ING
IPC: A61L2/20
Filed: 1973-05-23
Abstract: A gas sterilizer consists of chamber which can be evacuated and can be closed by door; a cartridge containing toxic gas is pierced to release the gas into the chamber. To prevent accidents, the door is locked by a cylinder as long as a vacuum is maintained in the chamber. This vacuum assists a spring inside the cylinder. To open the door, a vacuum will have to be applied to the other side of the piston. The gas cartridge is moved by a similar cylinder against a piercing pin only when a vacuum is maintained in the chamber. This prevents gas poisoning even when less skilled personnel operate the gas sterilizer, because the system is foolproof.

Title: Inductive heat hardening of strip-like material - is continuous process using HF or MF inductor with concentrators
Inventor: OVERKOTT FRANZ J
IPC: C21D9/60
Filed: 1973-12-17
Abstract: The inductive heat hardening of the strip material, such as steel rods etc, uses a continuous material feed and a high or medium frequency inductors. The concentrators, allocated to the inductors are displaced with respect to the former, in order to influence the power delivers by the inductor. This displacement can be axial. The relative position of the concentrators relative to the inductor may be continuously adjusted in accordance with the temperature of heated material at the inductor end, measured contactlessly and free from inertia. The material speed is preferably maintained constant. If the inductor is in the form of a semi-shell, the concentrators may be concentrically rotated. The concentrators displacement may be automatically controlled by the material final temperature.
