Title: Metal melt sampler - with coarse and fine ceramic screens for slag retention
Inventor: KOLB GUSTAV
IPC: C21C5/46
Filed: 1979-11-15
Abstract: The Parent Patent No. 2840745 described a sampler for molten metal baths with a slag cover, specially for steel melts, which consists fo a casing with a cavity for the sampel, joined by a riser channel to the melt. A ceramic screen directly at the face of the channel holds back any coarse slag particles an internal ceramic screen after the mixing cavity retains any fine slag particles. This ensures that the steel samples are free from slag, even when a more crumbly slag is used to reduce its attack on the lining. The larger slag particles which would have clogged the fine screen are thereby retained.

Filed: 1980-01-18
Abstract: A high voltage insulator bushing is formed of wound insulating foils and is provided with conductive parts which are at different electric potentials and with a wound insulator body arranged between the conductive parts. The wound insulator body contains layers of an embossed insulating foil which consists of a plastic material which shrinks above a predetermined temperature. The embossed insulating foil is subjected to a thermal shrinking treatment prior to being wound as part of the insulator body. Such preshrinking prevents further shrinkage which would occur when the high voltage bushing is operated. Smooth insulating foil may be wound as part of the insulator body so as to be interposed between the layers of the embossed insulating foil. The gaps and voids which are formed between the layers of insulating foils caused by the irregular surface of the embossed insulating foil are filled with an insulating medium.

Title: Emergency radio transmission from vehicle involved in accident - initiated by switch of passenger restraint system and powered by buffer energy store
Inventor: ENGEL VOLKER
IPC: B60Q1/52
Filed: 1980-07-23
Abstract: The proposed addition simplifies the equipment for switching on the transmission automatically. Instead of using a separate switch with an inertia element responsive to sudden deceleration it is proposed to use the switch provided for the passenger restraint system, e.g. an inflatable air bag. To allow for interruption of the normal power supply a buffer store is provided, activated by the same switch, to power the transmitter for a short period. The buffer may take the form of a reservoir capacitor or a small battery. The capacity of the buffer is enough to ensure that the emergency services can recognise the signal and obtain a radio bearing on the transmission. Manual operation of the emergency signal is unaffected.
