Patent DE-2059974-A1 (DE)
Title: Reactor control rod - electro-magnetically operated
Inventor: IRION LEONHARD
IPC: G21C7/12
Filed: 1970-12-05
Abstract: Reactor control rod operating mechanism in which linear motion is imparted by magnetic induction. The rod which is manufactured from magnetic material has an external spiral thread- and is surrounded by a magnetic nut formed of alternate spirals of magnetic and non-magnetic material. The rod and nut assembly are housed within a pressure vessel flange mounted on the reactor stand pipe.

Title: Sieving wet sticky material without clogging sieve - using inclined surface with transverse bars, pref with vibration of sieve
Inventor: BARTA SANDOR DIPL ING
IPC: B07B1/28
Filed: 1972-09-07
Abstract: Sorting granular, esp. moist and sticky materials according to their particle size, in which the material is fed onto an inclined surface of cords or rods extending transversely to the line of max. slope; the spacing between the rods exceeds the max. particle size to be sorted, and the material is moved during the sorting operation, pref. by vibrating the sieve, at such a speed that the particles below the predetermined sorting size just fall between the rods or cords, while those greater than that size just remain above them.

Title: Coke oven battery dust extraction - by mobile one-chamber cowl locally connectable to exhaust main
Inventor: MEURER WINFRIED
IPC: B08B15/02
Filed: 1973-05-25
Abstract: A dust extractor plant for coke over batteries includes a dust collection hood which fits around a single coke oven chamber and can be moved from oven to oven in line with the coke guide.
