Title: Lock with letter code without a key
Inventor: ILIEV ALBERT DIPL ING
IPC: G07F17/14
Filed: 1983-08-09
Abstract: For public locking installations, such as lockers, ski stores, hotel rooms, safes in hotel rooms, changing booths and other similar places for individual use, there has hitherto been no known lock which requires no key, is codeable and chargeable and offers locking by special code without any adjustment by the user. The abovementioned lock with letter code without a key affords this possibility. It is installed both in the door and in the frame and has a very simple mechanical construction. The selected code is stored by a system of two wheels lying one in the other and, after the opening of the door, is cancelled automatically by a decoder, so that the previously selected code is of no importance for the next use with another code. A coin makes it possible to execute the entire operation.

Title: Process for the pollutant-free disposal of refuse, in particular municipal refuse
Inventor: HERCHENBACH HORST
IPC: F23N5/00
Filed: 1984-04-21
Abstract: In a process for the pollutant-free disposal of refuse, in particular municipal refuse, in an incineration process, it is important that pollutants or toxins do not pass into the environment and contaminate it either through exhaust gas or through residues such as fly ash or scrubbing water. The majority of the currently conventional processes for refuse disposal do not comply with this requirement or comply with it only partially. The invention proposes that an amount of lime-containing carbonate carriers is added to the refuse such that the CaO content of the incineration product is at least 30 per cent by mass and that the refuse having the lime-containing and, in particular, calcium-carbonate-containing substances is transformed into the incineration product at temperatures of at least 1200 DEG C.   <IMAGE>

Title: Process for removing SO2 and NOx from gases
Inventor: FRICKE HELMUT DIPL CHEM DR
IPC: B01D53/60
Filed: 1985-01-15
Abstract: A process is described for removing SO2 and NOx from gases. In order, in particular, to provide a process which can be used in already existing flue gas desulphurisation plants, it is proposed, to remove the SO2, to subject the gas to a dry or wet purification process and, to remove NOx, to treat the gas with a scrubbing agent composed of up to more than half of tetraethylene glycol dimethyl ether. Preferably, the SO2 is also removed by this scrubbing agent, so that the possibility exists of scrubbing SO2 and NOx simultaneously in a single scrubbing stage or sequentially in two separate scrubbing stages.
Patent DE-3504007-A1 (DE)
Title: Keyed guitar
Inventor: SCHMITZ WILLIAM
IPC: G10D3/16
Filed: 1985-02-06
Abstract: The invention relates to a keyed guitar, in which the strings are no longer struck or plucked by the fingers of a hand or with the aid of a single plectrum, but via individual keys which are built into an appropriate position in the guitar body alongside the main bridge. The keys actuate hammer parts via an appropriate mechanism which strike against the strings of the guitar from below. A special floating mounting of the hammer parts results in an especially effective sound-volume ratio when the individual keys are actuated. The invention makes it possible to learn even the most complicated playing techniques very rapidly and also to strike chords which are not possible using the conventional playing method. As a result of this, innovative acoustic effects can also be realised.
