Title: Diagnostic X-ray appts with exposure control - has switch shunted by high resistance in series with triac shunted by capacitor
Inventor: GRASSME ULRICH DIPL-ING
IPC: H05G1/54
Filed: 1973-06-28
Abstract: The diagnostic X-ray apparatus is so designed that voltage peaks from the HV transformer cannot result in any undesirable firing of the triacs, nor can a defective triac cause X-rays to appear when the supply voltage fluctuates. The triac which switches the primary winding of the HV transformer for the X-ray tube has its gate connected to an mAs relay. An exposure trigger closes the switch, which is shunted by a 5 600 ohm resistor, as it actuates the relay to produce a firing voltage for the triac. A capacitor and a resistor across the triac reduce the inductive voltage peaks when the switch cuts in the primary winding.

Title: Plant for removing toxic components from flue gases by cooling - uses dry cooling tower and water spray scrubbed flue gases are added to cooling air
Inventor: HERTEL WILHELM DIPL-ING
IPC: B01D53/50
Filed: 1973-10-11
Abstract: Power generating unit flue gas washing plant for removing e.g. sulphur compounds from flue gases. The conventional existing cooling system are used additionally for cooling the flue gases to a temperature at which it is possible to precipitate the majority of toxic substances especially the sulphur compounds. Additional flue gas cooling plates are installed into a dry cooling tower over the cooling surfaces used for steam condensation. The flue gases are cooled in these elements in closed channels close to the ambient temperature. At the outlet of these elements are separators in which the sulphur diode is scrubbed from flue gases by means of water and removed downwards in a channel. The cleaned and cooled flue gases are mixed into the cooling air system, and the sulphur dioxide separated can be passed on for conversion into sulphur acid in the chemical industry. The circulation of air within the tower improves owing to higher temperature differences.
