Title: Load handling mechanism monitoring system - detects relative rotation between drive to load and measuring drive in parallel
Inventor: VOSS SIEGFRIED DIPL ING
IPC: B66D1/54
Filed: 1976-08-07
Abstract: The monitoring system is for load-handling mechanisms with lifting, travelling and slewing motions and brakes to halt load movement under dangerous conditions such as shaft breakage, distortion or excess wear of gears, supporting chassis etc. when a signal is emitted to stop the driving motor and engage the brake. Parallel to the gearbox driving the load an unloaded measuring drive is coupled giving the same overall ratio, and pref. to the free end of the motor shaft etc. to which no torque is applied. Under normal conditions the load and measuring drives run at the same speed, but they are coupled to a signal emitter, so that as soon as they start to rotate in relation to each other the motor is switched off and the brake applied.

Patent DE-2657826-A1 (DE)
Inventor: HOWELL THOMAS H
IPC: H03M13/15
Filed: 1976-12-21
Abstract: Apparatus for directly decoding and correcting double-bit random errors per word and for detecting triple-bit errors per word is disclosed. Said apparatus comprises a syndrome calculator which operates upon codewords received from memory and generates syndromes. The syndromes are operated upon and translated by a mapping device which generates pointers identifying the bits which are in error. The pointers are then passed through decoding means to generate error words which are summed with the received word from memory to provide a corrected codeword. The syndrome calculator may further provide a parity check signal to determine if a three-bit error is present, in which case the decoding means are not enabled and a signal is generated indicating that a triple-bit error has been detected which is not correctable.

Title: Electrochemical process esp. for moisture expulsion from masonry - uses conducting corrosion resistant electrodes esp. of fluorinated hydrocarbon
Inventor: TENGE HANS-WERNER
IPC: E04G21/24
Filed: 1977-02-11
Abstract: Appts. for carrying out electro-physical processes for influencing liquids in and on solids comprises anodes and cathods of the same material. Pref. the same inert materials are used for both anodes and cathodes, more specifically materials which are resistant to electroyltic, electrochemical, chemical (both inorganic and organic) and hydrolysis attack. An electrochemical potential of approx. 200 mV, esp. 50 mV, is produced in aq. electrolytes using identical anodes and cathodes. Used esp. for drying out moisture from masonry and other similar materials. The method enables a very low applied voltage to be used and is based upon the principle that the electrochemical potential between anode and cathode is zero or at least extremely small. This condition is associated with minimal destruction of the anode and/or cathode and results in long life. Both the corrosion of metallic anodes and the passivation of other types of anode are avoided.
