Title: Boiler feed-water loop safety circuit - tests salinity with two cation exchangers feeding conductivity measuring cells of difference amplifier
Inventor: ECKER ERNST H DR RER NAT
IPC: G01N30/96
Filed: 1979-06-15
Abstract: Risk of corrosion in the circulation loop of boiler feedwater due to seepage of brackish cooling water is eliminated by connectin connecting the piping of the heat exchanger to two cation exchangers (6,6').

Inventor: ZIMMERMANN ACHIM DIPL ING
IPC: G01B5/00
Filed: 1979-06-20
Abstract: The method of measuring small variations in a large distance between two measurement planes (OM,UM) occurring between two measurement time points is applicable to measuring displacements with machine bedplates and involves compensation of temp. effects on the measurement instrument. Two weighted measurement wires (MD1,MD2) of different linear thermal expansion coefficients beta 1 and beta 2 are suspended from the upper measurement plane (OM). They have lengths RO1 and RO2 at the first time point.
