Title: Temperature monitoring system for power cable protecting insulation - has high frequency cable with resistors at regular intervals
Inventor: HILDEBRAND HELMUT
IPC: H01B7/32
Filed: 1973-10-20
Abstract: The system is intended for monitoring the temperature of a power cable in order to protect the insulation against overheating. A high frequency cable is laid alongside and in physical contact with the main cable. The conductors of the high frequency cable are spanned by resistors with positive or negative temperature coefficient. The resistors are installed at measured intervals along the length of the cable. The reflection characteristics of such a monitoring cable will vary and will show up on an oscilloscope. If overheating should occur anywhere along the cable, the position will be established from the resistors sensing the change so that speedy remedial action can be taken.

Title: Electroslag remelting system for complex tube structures - joins central tube to prefabricated ancillary parts located in fixture
Inventor: UJIIE AKIRA
IPC: C22B9/18
Filed: 1974-10-25
Abstract: A tubular metallic structure which includes ancillary parts such as flanges, connections and hollow rings is produced by the electroslag-remelting process. The ancillary parts are prefabricated and located in a fixture at the desired positions. A tubular component is fused by the electroslag-remelting process and is joined up with the ancillary parts as it is being completed.

Title: Multilayer loudspeaker diaphragm production method - is from fibrous materials whose thickness density and kind varies from layer to layer
IPC: H04R31/00
Filed: 1974-12-21
Abstract: Fibres for each diaphragm layer are at first separately dispersed in water, and then precipitated as a felt-like fleece of the required shape. The complete diaphragm is then dried under pressure. After deposition of fibres for each diaphragm layer, dispersion solution is removed from each layer, and the still wet diaphragm layers are placed inside each other. The assembled diaphragm is then filled and covered with water, so that the layers are intimately felted with each other. Water is then sucked away through one of the layers.
