Title: Solid state iron prodn from powder or granule ore - by high intensity alternating current resistance heating
Inventor: VTR FISCHER A H DIPL ING
IPC: C21B13/08
Filed: 1971-07-13
Abstract: The extraction comprises the passing of highly conc. electric alternating current through the preheated raw material generating heat arising form the Joule-effect and electromagnetic forces resulting in the fast reduction and agglomeration into granules and rod shaped particles of the iron ore and the softening and separation of the gangue which coagulates into pumice stone.

Title: Gas engine running on oxygen hydrogen mixture - generates hydrogen by dissociation of steam in combustion chamber
Inventor: HOHMANN HERBERT
IPC: F01K25/00
Filed: 1974-05-21
Abstract: The engine has two small combustion chambers connected to a larger one by means of valves. The inner face of the chambers are lined with ceramic to withstand the temperatures involved. Hot steam is admitted through a valve and is heated further electrically or by residual heat from the previous explosion. Glow coils are provided in the cylinder walls for this purpose. The temperature dissociates the steam in to hydrogen and oxygen which then recombine explosively and pass into the main chamber where the combustion process is completed. The valves are controlled by the pressure of the generated gas which is admitted to valve cylinders. The steam formed is led back from the main chamber exhaust jet passage to the inlet valve.

Title: Speed control for motor - has reference oscillators frequency pulled by actual speed signal to avoid hunting convergence onto required speed
Inventor: CAUER ROBERT
IPC: H02P23/22
Filed: 1974-10-16
Abstract: The speed control, for a motor, has a comparator comparing the actual speed frequency and the required speed frequency and generating a regulating signal. The actual speed frequency is obtained from a pulse generator driven by the motor shaft and the required frequency is produced by an oscillator. A part of the actual frequency voltage from the pulse generator is fed to the required-frequency oscillator to pull its frequency. The advantage of this frequency pulling lies in its avoiding the 'hunting' convergence on the required value, due to the variation of the reference value with the speed of the motor.
