Title: Reducing gas and dust emission from a coal seam - using methane-oxidising bacteria and sealing with a polymer
Inventor: RSCHEVSKIJ VLADIMIR V
IPC: E21F5/00
Filed: 1976-07-02
Abstract: The emission of gas and dust from a coal seam is reduced by opening up the seam through cased holes drilled from the surface. Then fluids of different viscosity and acidity are injected in the course of hydraulic fracturing with seam cracks, and expanding and forming a single hydraulic system. Then liq. and gaseous reaction products are removed through the holes. Then a suspension contg. methane-oxidising bacteria, air and a nutrient medium for the bacteria is injected. Finally solns. of polymers or monomers, plus catalysts providing the transition to the solid state, are injected. The sequence of treatment steps provides a reduction in gas and dust not possible from any of the steps performed alone. The treatment can be effected through test walls specially designed for the purpose.

Title: Removal of oil from contaminated surfaces - by washing with aq. soln. of cationic emulsifier and sepg. oil from the emulsion
Inventor: CHAMBERS DAVID BRIAN
IPC: C23G5/06
Filed: 1976-08-11
Abstract: Removal of oil from contaminated surfaces by (1) washing with an aq. soln of an emulsifier which can be decomposed by varying the pH; (2) chaing the pH to partially break the emulsion, (3) sepg the oil from the aq. phase, (4) passing the aq phase through >=1 fibrous structures which cause the remaining oil droplets to coalesce; and (5) removing the sepd. oil. The process is used for cleaning tanks used for transport of mineral or vegetable oils, etc., cleaning undersides of road or rail vehicles, floors of buildings, and garages, etc. Use of hydrocarbon solvent in the wash fluid can be avoided. The emulsions formed are readily broken and most of the solid matter separates in the oil layer Over 99% of the oil droplets left can be removed in stages (4) and (5). giving relatively clean effluent water. In an example, arail tanker is cleaned with a 10% soln of trimethyl dodecyl oxycarbonyl methyl ammonium chloride in paraffin, diluted with 9 vols. water. 70% NaOH soln is added to break the emulsion, amd the aq. layer run through a non-woven polyester heterofilament fabric, of core/jacket type, contg. silane-coated silica particles.

Patent DE-2653574-A1 (DE)
Inventor: KOBEL KARSTEN ING GRAD
IPC: H02H3/44
Filed: 1976-11-25
Abstract: The tripping apparatus is particularly suitable for a railway installation. It has an integrator (17) which is connected downstream of the converter (10) in a first channel (14) and integrates the secondary-voltage pulses of the converter over a predetermined time, and has a comparator (18) in the same channel, which comparator compares the integrator output voltage with an adjustable reference voltage and, if the latter is exceeded, emits a trip command for a trip device. In order to achieve unambiguous and reliable differentiation between the short-circuit currents which are to be switched off and the operating currents which are not to be switched off, at least one further (15, 16) identically constructed channel, whose tripping limit can in each case be adjusted to a different value, is connected in parallel with the first channel (14) with its integrator and comparator. <IMAGE>
