Title: Process and portable assembly for multichannel metal UV spectroscopy
Inventor: STURM ADOLF PROF DR
IPC: G01J3/18
Filed: 1991-02-27
Abstract: Multi-channel UV metal spectrometers having high selection and high resolution generally require high-precision relative movement between slit and sensor plus extensive sensory electronic circuitry. The novelty is that during each measuring cycle of the opto-electronic bilinear sensor, switches open and close another measuring channel; that the sequential switches control polychromatic radiation from the receiving side ends of the light waveguide; that the incident beam always passes through the respective condensor and slot to impinge on the element from a different angle; that this produces an image from another spectral range on the opto-electronic converter with no relative movement of grid polychromator or light beam.

Title: Incinerator exhaust gas cleaner - has smelting reactor to dispose of toxic salts and heavy metals
Inventor: PONTO HANS-ULRICH DR
IPC: B01D53/73
Filed: 1991-03-15
Abstract: For the disposal of matter from exhaust gas cleaning plants, such as toxic heavy metals and organic materials and similar cpds., the material such as boiler ash (1), filter dust (2) and washing foams (3) are fed together to a smelting reactor (5). The reactor (5) gives an output in the form of a safe glass material (6), a residue (7) containing salts and heavy metals, and an exhaust (8) to augment the combustion air (14) for further thermal processing. The heavy metals and salts (7) are carried out of the smelting reactor (5) by the exhaust gas (9), to which ambient air (10) is added to give a rapid cooling to condense the salts and heavy metals (7) to be separated out by a filter (13). The conc. salts and heavy metals (7) can also be taken from the reactor (5) as a vitrified prod. from a number of outlets. Before the feeds (1,2,3) are passed to the reactor (5), they can be treated with one or more additives (11,12) for modification according to their physical and/or chemical characteristics and mixed together. The washing foam (3) can by sprayed or otherwise fed separately into the reactor (5) in a continuous or interrupted action. The washing foam (3) can also be used to pelletise and/or compress the boiler ashes (1) and filter dust (2). The additives are of synthetic and/or mineral waste in a suitable chemical composition esp. phonolite and/or quartz sand. USE/ADVANTAGE - The technique is for cleaning the exhaust from rubbish incinerators, to prevent toxic matter from being released. In a single assembly, the salts are removed, the toxic heavy metals are immobilised or removed, and toxic organic materials and similar cpds. are destroyed by heat.

Title: Hot sand bed gasifier for straw - has high throughput and provides gasification at very low temp. enabling plant to be simple and sturdy
Inventor: COST KARLFRIED
IPC: C10J3/12
Filed: 1991-10-22
Abstract: In sand-bed gasifier the straw is pyrolysed, gasified and burned in a hot sand-bed, and the heat of the sand, weight, very large surface area and the friction of the moving sand together act upon the straw. Temp. is several hundred kelvin below that of coat gasification, so that the plant heat-resisting requirements are much reduced. Plant is pref. arranged as a large vertical pipe, with a straw inlet, hot sand inlet, mechanical mixer, and low-temp. carbonisation gas outlet. Pyrolysis takes place, and the gases are drawn off. Sand/coke mixt. (the coke is the pyrolysis residue) descends further, and at a lower level a gasifying agent (air/O2/steam) is blown in. At a certain distance above this level there are suction outlets through which the gas prod. from the gasification leaves. Mixt. of sand and ungasified coke sinks further, combustion air is blown in for the coke that remains, and the gases from this are drawn off. Straw/ash mixt. is mechanically removed from the bottom of the reactor, the ash and hot sand are sepd. in another plant, and the hot sand is fed again into the top of the reactor. USE/ADVANTAGE - Variants claimed include: the use of metallic, ceramic or other particles instead of sand; removal of ash from the hot sand and re-use of this sand; and some constructional and operational details of the plant.
