Title: Removal of corrosive gases from incinerator smoke - by water washing in tower with pressure regulating system maintaining pressure in furnace
Inventor: KLEEBERG ULRICH DR RER NAT
IPC: B01D53/34
Filed: 1974-02-23
Abstract: Corrosive gases, particularly hydrogen chloride produced by the combustion of PVC, are removed from the smoke of an incinerator by washing with water. The dissolved corrosive gases are neutralised and then recycled to a gas cooler where the solution is sprayed into the gas emanating from the furnace evaporating the water. Crystals of the salt formed by the evaporation are removed in a cyclone or electro-static precipitator along with other dust from the furnace. The water washing tower operates below the saturation point of the corrosive gases and incorporates a press. regulating system which maintains a constant press. in the incinerator furnace enabling an exhauster fan of constant power to be used. Method prevents pollution of the atmosphere and allows easy disposal of corrosive substances.

Title: Timing signal phase relation changing method - uses frequency multiplier and divider
Inventor: REISINGER KONRAD DIPL ING
IPC: H03K5/131
Filed: 1974-03-25
Abstract: The timing signal pulse repetition frequency is multiplied, and two pulse trains of the same frequency are derived from the higher frequency timing signal. Each pulse of the second pulse train lags by a certain first phase angle behind a pulse in the first train, and leads by a certain second phase angle the next pulse in the first pulse train. The first or the second pulse train is applied through a switch first or second contact to the frequency divider, whose output delivers a signal with a changed phase. A switching circuit switches over the switch contacts during the above first and second phase angle, so that a pulse flank in the timing signal is advanced or retarded.

Title: Testing of HV power line - involves deriving test value, modulating it, transmitting it to low voltage side and demodulating
Inventor: BRAUN ANDREAS DR ING
IPC: G01R15/22
Filed: 1974-07-05
Abstract: The direction of energy transmission is automatically detected by a suitable circuit and pulses are generated at the h.v. side, whose repition frequency is proportional to the energy. They are so modulated that their pulse width is different for different directions of energy flow. Test values are transmitted by non-electric means, e.g. by a light emitting diode, light conductor and photodiode, and demodulated by a suitable circuit in order to be evaluated for the energy direction of flow determination. The polarity of the instantaneous value of current is determined in each period at the instant of the positive voltage maximum.

Title: Joining metal parts of domestic ware etc by connecting elements - latter pressed into one component which undergoes plastic deformation and anchors element
Inventor: BLECKMANN RICHARD DR ING
IPC: F16B11/00
Filed: 1974-12-23
Abstract: In the fixing of connecting elements (I) to a metal part (II) made of plastically deformable material by using pressure the elements are made of a harder material than metal (II) which is stressed beyond its yield point by the pressure so the largest cross section of elements (I) penetrates some distance from the surface of the metal part (II), which flows round the elements (I) directly or indirectly, to close or reduce the zones where the penetration occurred so that the elements (I) are securely anchored in the parts (II). A suitable number and pattern of the elements may first be joined to a second metal part by welding, enveloping around soldering or pressing. Used on cooking utensils, hot plates irons kettles, food cans, radiators.
