Title: Testing concrete containers for porosity - measuring resistance and potential difference between probe and conductive lining layer
Inventor: NEUMANN JOERG DR ING
IPC: G01M3/40
Filed: 1975-03-11
Abstract: After the initial known h.v. test continuous test is performed during sevice. A conductive layer is necessary between the lining and the wall of the container and an electrode is inserted into the fluid in the container. In the event of leakage through pores, the electrode closes an electrical measuring chain in which a resistance, current or voltage measuring bridge indicates the leakage. Pref. if pore leakage is discovered using the immersion electrode, the container is emptied and the location of the leakage is discovered using the conventional h.v. technique. The electrode can be built into the tank structure as a permanent unit or used for regular checking. Whichever way is chosen, leaks can be detected at an early stage before the aggressive fluid can cause major damage to the container.

Title: Primary current stabilised X-ray tube supply - uses paralleled regulated load fed through common series resistor
Inventor: ROSENFELDT WOLFGANG
IPC: G05F1/445
Filed: 1975-04-12

Title: Electrical drive for reciprocating compressor - has three phase inductor and field reversal system
Inventor: KIRN HERBERT ING GRAD
IPC: H02K41/03
Filed: 1975-07-11
Abstract: The reciprocating compressor or pump driving rod is connected directly to the armature (Wk) which typically takes the form of a short circuited winding similar to that of a cage type induction motor. The armature is enclosed by a three phase field system (Wi) which generates a linearly moving magnetic field when supplied with alternating current, and thereby causes the armature to move. At the end of each stroke the supply connections are reversed thus changing the field travel direction by 180 deg. and reversing the stroke. Reversal of supply leads is with advantage accomplished by a solid state switch typically composed of thyristors. Performance is improved by incorporating a spring (F) coupled to the armature and tuned to the oscillating frequency.

Title: Loading and unloading radioactive materials - using a cask submerged in a contaminated pool and surrounded by fresh water
Inventor: WODRICH DONALD DICKOVER
IPC: G21F5/14
Filed: 1975-07-14
Abstract: A nuclear material cask is placed in a sealed zone submerged in fresh water in a container continuously supplied with fresh water under pressure. The container and cask are lowered into a contaminated water pool, where the cask is loaded and/or unloaded, while maintaining excess fresh water pressure to exclude contaminated water. The cask is then raised to the surface and removed from the container. The method is used in handling casks for long distance shipment of radioactive material. Radioactive contamination of the outer walls of the cask by the pool water is reduced.

Title: Compensated bellows system for diff. pressure measurement - has double flexible chambers with electromechanical transducer
Inventor: TWISSELMANN LORENZ DIPL ING
IPC: G01L13/02
Filed: 1975-09-29
Abstract: The pressure and differential-pressure measuring apparatus consists of two corrugated tubes in the form of opposing bellows. The small differential force resulting from the subtraction of forces on the separate faces of the bellows, can be compensated using an electro-mechanical transducer whose output is proportional to the pressure difference. The measuring cell comprises a pressure container with two inlets. One inlet is connected to a reference pressure Po, the other to the unknown pressure P1. The different pressures act on the respective bellows (W1, W2) which have operating surfaces of different size. A force compensator (K) uses an electro-mechanical system such as a moving-coil transducer. The arrangement automatically compensates for temp. effects.
