Title: Electroslag remelting system - with screened electrode by light-weight disc floating on slag for better thermal efficiency
Inventor: RABINOWITSCH WOLF JU
IPC: C22B9/18
Filed: 1975-11-07
Abstract: In an electroslag remelting process the electrode is screened only after the slag has become liquefied and a molten pool of metal has been produced. A disc with a central hole for the electrode is lowered on the surface of the bath so that it floats on the slag without touching the molten metal. The material of the disc has a lower density than the slag but a better conductivity. This improves the efficiency of the electroslag remelting process because the heat produces is entirely used for melting the electrode and heating the bath. The oxidation of easily oxidisable elements in the metal is eliminated.

Title: Animal carcass quick refrigeration - uses refrigerating tunnel with cooling air stream velocities adjusted to carcass part thickness
Inventor: TAMM WALTHER DR ING
IPC: A23B4/06
Filed: 1975-12-24
Abstract: Refrigeration unit consists of a long, narrow tunnel with partition at one narrow end fitted with recirculating fan. The partition forms a chamber containing air cooling coil. Cooled air is blown at ceiling level along the length of the tunnel in which the carcasses are hung on support. When the air stream reaches the opposite end of the tunnel it is divered, turned back at the entrance door and returned via a false ceiling to the air cooler. Tunnel has a number of baffle grilles placed at certain distances. The grilles are of perforated sheet metal with dense perforation at the top part, which prevents intensive longitudinal cooling air flow where the thick parts of the carcass are located. The longitudinal air flow gradually increases towards the middle parts of the carcasses and is highest at the bottom part.

Title: Warning device for seat belt wearers - has optical and or acoustic warning which switches on automatically with ignition switch and is manually switched off
Inventor: STEUER HERBERT
IPC: B60R22/48
Filed: 1976-01-07
Abstract: The warning device is for reminding vehicle drivers and passengers to fit safety belts and provides an optical and/or an audible warning which can be manually switched off. The device is added to the ignition switch (1) which when closed passes current through a closed switch (4) to a light (35) and a buzzer (2). To switch off the signal the passenger closes a pressure switch (8) allowing current to pass to a magnet (5) to open the closed switch (4) thereby cutting off the signals. When the ignition is switched off, the power to the magnet is cut off allowing the closed switch (4) to reclose in readiness for the next journey. This enables a warning device to be fitted to the vehicle after assembly which does not limit the choice of the driver of whether to wear a seat belt.
