Patent DE-2538555-A1 (DE)
Title: Spherical industrial steam generator - has compressed air and water droplets heated directly by burning gas
Inventor: PILZ FRANZ
IPC: F22B1/18
Filed: 1975-08-29
Abstract: The industrial steam generator heats a mixture of air and water droplets. The water evaporates and steam generation is rapidly matched to the continuously fluctuating demand levels without loss of efficiency in steam generation. The water is atomised by compressed air into fine droplets. The droplets are evaporated by hot combustion gases in burning fuel and air mixture. The steam and exhaust gas mixture generated is drawn off for consumption elsewhere. The evaporator has a spherical housing (1) with a row of radial nozzles (6, 7) for injection of compressed air, water and fuel.

Title: Ring spinning or twisting underwinding crown - has a thread catching pot round the crown mantle for easy thread severing
Inventor: BEREND WOLFGANG
IPC: D01H1/38
Filed: 1975-10-06
Abstract: A spindle appts. is claimed for use with a ring spinning or ring twisting machine, particularly a cord twister. An underwinding crown for underwinding the thread is located on the spindle below the spool but above the whirl, with a cylindrical mantle ranging up to a proud ring edge as a cutter acting with a blade. A thread catching pot surrounds the cylindrical mantle of the underwinding crown with an open top. Its circular base ranges outwards from the lower end of the mantle. A circular gap is located between its outer wall and the circular edge as far as the height of the upper end of the mantle. The design ensures that when the full spool is removed, the thread is parted easily without interfering with adjacent spools and, when winding flanged spools, the cutter does not sever the thread accidentally when the ring rail is raised.

Title: Gas turbines working in closed cycle - have counter stroke thermostats to control combustion chambers
Inventor: VESTER GERHARD
IPC: F02C1/10
Filed: 1976-04-07
Abstract: An endless acceleration tube (7) is filled with a working medium such as a gas or liquid. The tube contains two function units each enclosed by an annular closed combustion chamber (A, B).

Title: Rotational velocity transducer with pulses at proportional frequency - is particularly suited to liq. flow rate measurement devices using immersed impeller
Inventor: DUELL PETER G DIPL ING DR TECH
IPC: G01P5/06
Filed: 1976-10-08
Abstract: An angular velocity transducer produces a pulse train of frequency proportional to that angular velocity, which is suitable for use in a liquid flow rate transducer. An impeller wheel (2) is immersed in the liquid in a suitable tubular chassis (1) and rotates at a rate proportional to the flow rate of the liquid.

Title: Boiler fuel gas and air supply system - has turbulent mixing channel and divided outlet channels ensuring optimum combustion
Inventor: ZENKER KURT DR ING
IPC: F23D14/62
Filed: 1976-11-17
Abstract: The arrangement for supplying and ignition of a fuel gas and air mixture is used esp. for a radiating heating boiler. Turbulent mixing of air and gas takes place in the supply channel and this mixture is blown into a combustion chamber (3). Optimum heating effect takes place in the burner and the combustion chamber area, and this ensures optimum performance in the actual radiation and convection area of the boiler. The mixture components are mixed roughly at first. This mixture is converted into an isentropic turbulent flow with fine turbulence structure. This stream is accelerated and the stream is divided into individual streams and ignited directly downstream of the dividing area on transition into the combustion chamber.

Title: Totally enclosed motor with squirrel cage rotor - has heat transfer structure surrounding stator windings assisting rotor cooling
Inventor: KRAUS KURT
IPC: H02K9/22
Filed: 1977-03-14
Abstract: The application is typically to totally enclosed torque motors which can be operated for appreciable periods at a speed well below the synchronous. In order to remove heat from the rotor, thermally conducting inserts (4a) are placed in the stator slot openings. These are then attached to the stator frame (1) so that the heat is dissipated to the surrounding air. The stator end windings (3) can also be enclosed by the heat transfer system (4, 4b). In addition to acting as a heat sink for the rotor thermal losses the structure (4) also serves as a thermal shield for the stator windings. The thermally conducting material is normally copper or aluminium.
