Title: Transceiver for locating buried cables - passes medium frequency current through cable and detects stray field
Inventor: KLIMKEIT HANS JOSEF
IPC: G01V3/06
Filed: 1977-08-05
Abstract: A transmitter (S) generates a medium frequency signal in the range 25KHz to 125KHz, pref. 62.5KHz. It is coupled to the neutral poles (5, 6) of socket outlets in the wiring of a building.

Title: Cooling hot objects esp. chill moulds for ingots - using stream of air contg. fine drops of water (SW 14.8.78)
Inventor: LARSSON BERTIL
IPC: B22D27/04
Filed: 1978-01-16
Abstract: Hot objects are cooled, esp. chill moulds for ingots, by directing a stream of air onto the moulds for >=1 period of time. Fine drops of water are distributed in the air stream. The air is prf. fed through nozzles to increase its velocity, and then meets sprays of water flowing in the opposite direction to the air so an air-water mist is formed and flows onto the moulds. Cooling pref. consists of (a) directing pressurised water onto the moulds; (b) using an air-water mist; and (c) using an air stream contg. no water. The pref. plant has rails via which the moulds are fed into a chamber fitted with air and water nozzles for the three periods(a,b,c). In period (a), the water jets blow casting residue and casting powder off the mould. Conventional air cooling of moulds takes e.g. >12 hrs. The above process reduces this cooling time to 4-5 hrs. so the moulds are more rapidly available for re-use.

Title: Diagnostic X=ray generator with automatic tube current adjustment - switches resistors in primary voltage supply to compensate changed tube voltage in dependence on tube current
Inventor: KLAUMUENZER HARTWIG ING GRAD
IPC: H05G1/54
Filed: 1978-12-02
Abstract: The generator improves diagnostic operations with dropping load by replacing the rigidly preprogrammed course of the rated value using a capacitor and discharge resistor. The decreasing X-ray tube current is automatically adjusted using automatic comparison of actual and rated values and determination of their magnitude. The change of the X-ray tube voltage, resulting from changes in the tube heating current, is compensated by connecting resistors into the primary circuit of the tube current supply in dependence of the tube current. Pref. the actual tube starting current is stored in a starting current memory, supplied to a voltage divider and, on underreaching certain partial values of the tube starting current, contactors are enabled into switching state to effect the connection of the compensation resistors into the primary circuit. The max. permissible X-ray tube rated current value may be preset for each focal point and for each time instant.
