Title: Electricity meter protection circuit - using magnetic field recording element to indicate possible falsification of readings
Inventor: DELLIEHAUSEN KLAUS DIPL CHEM D
IPC: G01R11/04
Filed: 1975-08-08
Abstract: The method detects if an electricity meter has been subjected to a strong magnetic field in order to falsify the reading of energy consumed. It consists of incorporating a permanently magnetic material in the plastic casing in such a way that a small mark dependent on the magnetisation of this material can be examined when the meter is read. Any change or obliteration of this mark can be observed either with a probe or magnifying apparatus, and this signifies previous application of a magnetic field.

Title: Sorter for dust particles by different sizes - has auxiliary air streams to carry very fine particles to separate bin
Inventor: HILLEKAMP KLAUS DR ING
IPC: B07B7/01
Filed: 1975-12-16
Abstract: The machine for sorting dust particles into different sizes consists of a cylindrical shell surmounted at one end by a hopper. The ungraded dust slides from the chute through the hopper into the interior of the shell. An air stream induced by the fan passes through the air straightener and blows the dust towards the outlet duct. The falling dust is separated into three grades which fall into the hoppers. A system of ducts are fitted with fans which suck air through the openings and blow it under sieves so that it returns to the interior and carries the lightest particles out through a duct around the swirl inducer and out through another duct.

Title: Removal of radioactive iodine from impure air streams - by preheating the air or heating the adsorbent
Inventor: WINTER KARL DIPL PHYS
IPC: B01D53/02
Filed: 1975-12-24
Abstract: Separation of radioactive iodine from a stream of air charged additionally with organic impurities, is carried out at elevated temp., either by pre-heating the air to be purified or heating the iodine absorption medium. Method enables the iodine content to be reduced below the upper tolerance limit despite sharply varying amts. of organic impurities. The air be treated enters a heat exchanger where it is heated indirectly by e.g. steam, hot gases or electrically to the desired temp. controlled via the senser. The hot air then enters the absorption unit where the radioactive iodine is retained on an adsorption medium. Further temp. sensers control the inlet and outlet temps. of the air stream. A fan draws the clean air away and delivers it to a chimney discharding to atmosphere.

Title: Backflushing filters with pulsed injection of purge fluid - after partially emptying vessel with compressed air
Inventor: FRIEDRICHS DIETER
IPC: B01D29/62
Filed: 1976-01-19
Abstract: Process for purging filter chambers in a filtration unit with several chambers interlinked involves taking the chamber off stream and opening a sludge drain valve. A compressed air or gas source is then used to expel the slurry and deposit cake, acting against the normal filtrate flow. First of all the dirty side of the filter chamber is at least partly emptied. Then a backflush of purge fluid is injected under pressure as a sudden pulse. The clean side is first partly emptied. At least part of the incoming purge liquid is accelerated and injected into the clean side of the filter chamber. The mixture of slurry, residues, purge filtrate and compressed gas is collected in a sludge tank. Uniform and complete cleaning of the filter surface is obtd.

Title: Solvent recovery from air of dry cleaning machine - by varying vol. of air for drying by condensation and adsorption
Inventor: ZIMMERMANN MARTIN RICHARD
IPC: D06L1/10
Filed: 1976-10-11
Abstract: Solvents are recovered from the circulating and outgoing air of a dry cleaning machine, in which circulating and fresh air drying occurs by means of condensation and adsorption, is carried out by varying the air flow vol. according to conditions which determine recovery by condensation and adsorption. The air vol. is pref. reduced to 1/10 of the initial vol. during circulatory air drying, and increased again from a low level during fresh air drying after a fresh air interval. Pref. the air is heated up before entering the material to be cleaned, and the heating and/or cooling energy is reduced with the decreasing air vol. Dwell times of the air laden with solvent vapours in the material being cleaned and in the condenser and adsorber and in the heater are thus controlled to provide optimum recovery conditions.
