Title: Replacing granular filling in a gas filter - the operation continuing as the filtration proceeds
Inventor: WEISS VIKTOR DIPL ING
IPC: B01D46/30
Filed: 1978-05-11
Abstract: A layer of spent filter material is mechanically scraped from the surface of the filter packing nearest to the compartment contg. the non-filtered gas and falls into this compartment from which it is removed. The filter packing is replaced from a supply at the top of the filter. Periodically the whole packing is changed. While this is being done a counter flow of air is passed through the appts. to stop impurities escaping into the clean gas compartment. The process avoids the escape of the dust particles during the replacing of the filter medium and thus avoids pollution. The efficient life of the filter packing is lengthened and the time taken up in replacing the filter is reduced.

Patent DE-2825809-A1 (DE)
Inventor: HUBER LUDWIG
IPC: F24H1/12
Filed: 1978-06-13
Abstract: A continuous flow water heater utilizes a submersible pulsating heating mechanism. A continuous flow water heater is provided with a caldron which may be closed by means of a cover. The pulsating heating mechanism may be mounted to the caldron cover with the pulsating heating mechanism and the cover being readily removable. The pulsating heating mechanism extends downward into the caldron. The pulsating heating mechanism is formed by a vertically standing sound muffling air cylinder with an intake muffler, a combustion chamber and a pulsation pipe connected to the combustion chamber. The pulsation pipe exhausts into a cylindrically shaped substantially vertically mounted exhaust muffler cylinder mounted adjacent to the air cylinder within the caldron. The caldron may be made of a synthetic material as the highest temperature which it must withstand is that of the temperature of the water to be heated. The water to be heated enters from the bottom of the caldron, is heated by the air and exhaust cylinders as it rises, and is heated to its highest temperature near the top of the caldron where it exits by means of a pretzel-shaped pulsation pipe. The heating capacity may be doubled by using a second substantially identical pulsating heating mechanism which operates 180 DEG  out of phase without increasing the volume of the exhaust cylinder.
