Title: Dessicant filter - for radioactive gases with slump inhibiting make-up vessel
Inventor: NEUMANN GERHARD MAX
IPC: B01D53/04
Filed: 1971-12-20
Abstract: A dessicant type filter e.g. activated carbon, for filtration of air-borne or gaseous radio-activity in which the formation of free-air paths within the filter bed due to slumping is inhibited by an upper storage vessel connected to the filter chamber.

Title: Highly constant resistors - with carbon and organo-silicon insulating coatings produced on ceramic by pyrolysis
Inventor: KOSCHKINA LIDIJA PETROWNA
IPC: H01C17/02
Filed: 1971-12-30
Abstract: Resistors are produced by applying to a ceramic substrate an electrically conducting layer of C, obtd. by pyrolysis of hydrocarbons at 900-1050 degrees C, an insulating layer being applied, at least on one of the C surfaces, by pyrolysis of organo-Si cpds., e.g. dialkyldialkoxysilanes, at 850-950 degrees C. The resistors can be used for electronic communications equipment. The resistance layer is protected against outside influences. The insulating layer covers all surface flaws and roughness of the substrate, thus increases the homogeneity and closeness of the resistance layer and improve the resistance stability towards electrical and climatic influences. The outer insulating layer protects the resistance layer against adsorption of vapours and gases from the surroundings and thus also improves the resistance stability.

Title: Nuclear power station operational system - for reduction of power output with lower demand
Inventor: GRIGORIEWITSCH ILJUNIN WLADIMI
IPC: G21D5/14
Filed: 1973-10-12
Abstract: The station uses two fast neutron reactors, one of the breeder type meeting base load in part and also peak demands operating at lower temp with its primary coolant circuit supplying the main heat exchanger.
