Title: Cracked gas reactor - using two separate swirling primary air streams and central fuel nozzle for optimum mixing
Inventor: SOBEK FELIX
IPC: C01B3/36
Filed: 1974-01-31
Abstract: Cracked gas is produced by introducing the prim. air for the substoichiometric combustion in the reaction chamber by two separate swirling air streams of different cross-section, flow rate and pressure. The fuel is introduced by a central nozzle at an atomization angle to penetrate the swirling air streams and to impinge in a cross stream of the air particles for intensive mixing and turbulence. Abrupt cooling to 400 degrees C in the last stage. The result is an improved mixing between fuel and oxygen molecules combined with a shorter dwell period in the reaction space. The low air factor (under 0.2) produces a cracked gas of higher calorific value than is obtainable by conventional processes. The gas qualities can be varied over a wide range by simple changes in the material compsn.

The diamond division is chosen according to the refractive index with a reducing number of corners on reducing refractive index.
Patent DE-2415865-A1 (DE)
Title: Diesel motor air cooling system - using cool air produced above the engine block by a blower ventilator unit, thermostatically controlled
Inventor: SCHMITZ RUDOLF WERNER
IPC: F01P7/12
Filed: 1974-04-02
Abstract: Alteration control in the cooling system for air-cooled diesel engines, consists of the cooling source operating from above the motor unit instead of being placed in front of the engine block with conventional systems. This change ensures that the cylinder heads are directly cooled from above by a cool air flow produced by a rotor type ventilator blower. The thermostatic control of the sealing source ensures that the required degree of cooling is rigidly adhered to. There are normally two separate cooler units in the system so that even in the event of one unit being out of operation the remaining unit prevents any serious damage to the motor during normal operations.

Title: Cable stranding machine - has braking device on core take-off mechanism with braking power automatically adjusted
Inventor: HOLLAND KARL HEINZ
IPC: B65H59/16
Filed: 1974-08-02
Abstract: The cable stranding machine is adjusted to the pulling force applied to the core by a coupling depending on the pulling force, thus ensuring uniform pull is applied to the core. The core is passed between two fixed smaller pulleys and a larger pulley mounted on a spring loaded lever (9). The swingable pulley (4) is magnetic or carries a permanent magnet. A magnetic disc (5) on a lever (7) is opposite this pulley (4) and can swivel about a threaded bolt (8), so that the disc (5) is pulled by the pulley (4) when it is deflected by an increased core (1) tension. At the same time its distance from the pulley (4) is increased, sot that the braking torque and pull are reduced. Damping devices are provided to damp the pulley (4) and lever (7) oscillations.

Title: Current source for magnetron transmitter - has low ohmic transmission tube and used Chopper dc voltage in ultrasonic frequency band
Inventor: FRITZ KARL DR
IPC: H03B9/10
Filed: 1974-08-30
Abstract: The current supply source is intended for microwave transmitters, such as magnetron transmitters, and uses a low ohmic transmitters tube. The main voltage is rectified and chopped, using ultrasonic frequency. The used ultrasonic frequency is transformed magnetically to approximately half the effective anode voltage. This voltage is transformed to the final anode voltage value by a single-or two-stage cascade. The anode current is stabilised by control voltage derived from the anode circuit which controls the input assembly. The arrangement enables earthing of the magnetron anode together with reduction of weight and cost, as compared with previous systems.

Title: Transfer arm for cigarette pack blanks - has two parallel hinged bars on suction head
Inventor: SCHUBERT BERNHARD
IPC: B65H3/30
Filed: 1974-11-30
Abstract: A cigarette packing machine for hinged lid packs uses a transfer arm to move the lowest blank (4) from the supply stack (3) to the machine. The transfer arm has a suction head (1) which consists of three parallel bars (14, 16, 17). After a blank is held by the head due to suction, the outer two members fold downwards about pivots (18, 19), whilst the stack brackets are momentarily retracted (7, 8).
