Patent DE-4022087-A1 (DE)
Title: Converting solvent-laden gases into frozen snow - in which has purificn. stream descending towards base separator
Inventor: GEIER-HENNINGER KURT
IPC: B01D53/72
Filed: 1990-07-11
Abstract: Waste gases contg. light or heavy organic pollutants such as benzene or benzol are fed by a pipe  into a bath of liq. contg. foaming agent, forming multiple small bubbles which tip over an end partition into a shaft, cooling into snow while descending a chamber cooled by a deep-freezing evaporator. While water content freezes, solvents in the gases are converted into liq. leaving the gas purified. Solvents collect in layers, based on gravity, in a separately mounted PVC freezer vessel, and are removed via a solenoid valve, leaving the frozen water ready for melting if necessary and re-use. ADVANTAGE - Process is simple, needing little  maintenance, and low cost of foaming agent is compensated by recovered solvent value.

Title: Acoustic separation transport monitoring system - automatically adjusts measurement or frequency range to thickness of paper sheet in paper or printing industry
Inventor: SCHWARZ SIEGFRIED
IPC: B65H7/06
Filed: 1990-07-13
Abstract: An arrangement for acoustically monitoring a desired sequence of objects (6,6a) passing a monitoring station one at a time contains a sensor unit with a transmitter (1), a receiver (2) and evaluation electronics (3). There are no manual adjustment facilities. When an object first passes the monitoring station a microprocessor system in the evaluation electronics automatically adjusts to the thickness of the object, e.g. by detecting and storing the alternating sound pressure at the object and adjusting the receiver gain. The optimal  measurement or frequency range is automatically selected for the object. USE - Collecting machine, e.g. for sheet, plate, foil or ribbon material in the paper or print industries.

Filed: 1990-07-21
Abstract: An electric dryer, in particular a hairdryer having an electric heater 10 and a blower motor 20, is proposed, the heater 10 having a plurality of resistors 12, 14 connected in parallel, and it being possible to vary the heating power by means of electrical switchgear in accordance with a settable desired value 40 by means of multi-cycle control. In this arrangement, the at least two resistors 12, 14 are in each case assigned a controllable semiconductor component 28, 30, in particular a triac, and means are provided which prevent simultaneously switching of the semiconductor components 28, 30. It is thus possible to carry out practical temperature regulation even for high heating powers. <IMAGE>

Title: Method of using refuse and other burnable waste - by partially burning in air deficient atmos. then burning in exceair in IC engine
Inventor: BLASCHKO SIEGFRIED
IPC: F02B45/08
Filed: 1990-09-28
Abstract: Method comprises gasification of these materials by partial burning with an air deficiency followed by burning of the resulting gases with an excess of air in an internal combustion engine. Before gasification, the waste materials are dried and preheated by heat exchange with the fuel gases, and finely atomised water is added to the fresh air and/or the fuel gases immediately before they are fed to the engine or immediately before compression. There are a number of variants both for the method and for the plant, including the engine. A pref. embodiment of the plant has two main parts; the reactor (2) for gasifying the refuse and the piston-type internal combustion engine (4). To start the plant, the reactor chamber (14) is charged with burnable refuse; electric heating (12) e.g. glow plugs in the ceramic insertion(8) is used for the gasification. Any necessary fresh air is fed in at the entries (20). Slow burning begins in the reactor chamber (14) and gives carbonaceous fuel-gas which dries and preheats the refuse above it. USE/ADVANTAGE - The method, as compared with others, enables a greater amount of energy from refuse to be converted into useful mechanical work. The plant's internal  combustion engine can also be used with other fuels.

Title: Foamed glass - used as chemical carrier medium esp. for delayed release of artificial fertiliser
Inventor: MUELLER-HOLTZ CHRISTOPH
IPC: C05G3/00
Filed: 1991-03-08
Abstract: Foamed glass, as carrier medium for agricultural chemicals, is claimed.

IPC: A61K36/16
Filed: 1991-04-02
Abstract: Extracts of Ginkgo Biloba leaves are used for the prodn. of medicaments for treating sleep apnia.

Patent DE-4111855-A1 (DE)
Inventor: PLENGE GEORG
IPC: H04H20/33
Filed: 1991-04-11
Abstract: The invention concerns a process for radio transmission of a data stream in an already occupied frequency spectrum without disturbing the stations already allocated to the spectrum. To this end, a plurality of RF carriers modulated with the data stream are transmitted either in the frequency spaces between two FM stations ofadjacent frequency ranges at the same place or in the free frequency ranges on either side of an FM station, while avoiding this allocated nominal frequency. The level of the plurality of RF carriers is set sufficiently low in comparison with the level of the RF carrier of the FM stations of adjacent frequency or of the central FM station to obtain a sufficiently large signal-to-noise ratio in the FM reception of the FM station(s) but sufficiently large to preclude interference from the geographically remote FM stations which fall in the frequency range or frequency spaces reserved for the transmission of the plurality of RF carriers. The data stream which modulates the RF carriers has an enhanced error protection to preclude interference from the FM stations of adjacent frequency or from the central FM station.
