Title: Roasting of fine-grain iron sulphide material
IPC: C22B1/16
Filed: 1971-04-19
Abstract: Roasting of iron sulphide material, in particular pyrrhotite or another pyritic material, from which sulphur was expelled by a partial roasting or another thermal treatment, is improved in that the sulphidic material is agglomerated e.g., by rolling or micropelletizing to a size suitable for a fluidised bed roasting; then roasted and simultaneously hardened in a fluidised bed (pref. at 700-1100 degrees C, under a controlled partial pressure of oxygen), and withdranw therefrom in the hot state.

Title: Heat-source regulated circulating water heater - with regulators adjustment of supply ducts temperature influenced by cold water supply temperature
Inventor: MEIER HANS
IPC: F24D19/10
Filed: 1974-07-13
Abstract: The circulating water heating system incorporates a heat source e.g. geyser which can be adjusted for output, a heat-exchanger heated by this and connectable to another heat-exchanger for draw-off water heating, circulating pump, and regulator for reading off the temperature of the supply duct between heat-exchanger and draw-off water treatment unit and controlling the heat source. The regulator for the heat source adjusts the temperature of the supply duct according to the output derived from the draw-off water treatment unit, being affected in this process by the temperature of the cold water intake, which may accommodate a heat sensor and water switch connected in series. A constant outflow temperature for the draw-off water can be achieved independently of flow and temperature of the cold water intake.

Title: Steam generating gas cooler - for synthesis or cracker gases with improved hot gas pipe arrangement
Inventor: VOLLHARDT FROHMUT
IPC: F28F9/00
Filed: 1974-12-10
Abstract: In a cracker or synthesis gas cooler for generating steam, of the known type having a heating tube bundle of gas transporting tubes installed vertically in a circle round a central guide pipe and surrounded in turn by a guide sleeve or baffle, the heating tubes are installed in staggered array in a series of concentric circles surrounding the guide pipe and spaced from each other by a distance of about one tube diameter.

Title: Underwater electrical signal transmission system - uses sea as transmission medium and generators coupled to submerged electrodes
Inventor: PRICHODJKO ALEXANDER
IPC: H04B13/02
Filed: 1975-03-14
Abstract: The underwater electrical signal transmission system, for transmitting electrical signals into the depths of the sea and horizontally through it using the sea itself as transmission medium in place of air, has its transmitters each connected via isolating transformers to feed lines leading to electrodes placed beneath the surface of the sea or on the surface. Electrical signals are propagated through the sea water between electrodes and their information retrieved from variations in their electric and/or magnetic fields. The system uses extremely low frequencies, e.g. 200 Hz., for transmission over the large stretches of water.
