Title: Machine-tool numerical control circuit - has X-axis and Z-axis adaptive control using an adder to vary the displacement requirement
Inventor: MEYER JUERGEN DR
IPC: G05B19/416
Filed: 1973-09-27
Abstract: The displacements are controlled through a digital integrator consisting of a store for the displacement, a pulse stepped adder and a sum store. The adder is enabled by pulses derived from the rotation of the machine. The output of the sum store gives the X and Z drives. The displacement store contains a value which is controlled by a cutting parameter difference signal. This comes from a comparator fed by the set-point and measured variable. The value after limiting by constants is fed to a voltage controlled oscillator the output of which, dependent on the sign of the signal is gated into the add or subtract ports of an adder. The adder controls the displacement store value. Thus when the tool is far from the required position it is moved quickly and it is slowed as the position is reached.

Title: Method for detection of defective pipe in bundle - uses medium which flows through parallel pipes with pressure difference between inside and outside
Inventor: KUMPF HERMANN DIPL ING
IPC: G01M3/02
Filed: 1974-01-18
Abstract: The method has been developed with special reference to heat exchanger tubes in pressurised water reactors. Two ends of one of the pipes are closed by valves. After a time allowed for the pressure equalisation in case of a leak, an effort is made to open the valve, and the force necessary for it is compared with that when no leak is present. Force applied during this test is less than that necessary for valve opening when a leak is present, so that leaky pipes remain closed. The valves are connected to their driving shafts by a shear wire.
