Title: Operating and braking circuit for several AC motors coupled via load - has single brake switch connecting braking resistance bridged by free-running diode across DC voltage rail pair supplying all motors
Inventor: WEGENER KLAUS ING GRAD
IPC: H02P5/74
Filed: 1992-10-13
Granted: 1993-11-11
Abstract: The circuit for an AC network (1) has a choke coil (1.5, 1.6 - 5.5, 5.6) bridged by a free-running diode (1.12, 1.13 - 5.12, 5.13) acting as a coupling between a DC voltage rail pair (14, 15) and an intermediate DC circuit capacitor (1.3 ... 5.3) of each motor (19). A braking resistance (10) bridged by a further free-running diode (11) is connected across the DC voltage rail pair (14, 15) via a brake switch (12). An auxiliary capacitor (6) is coupled to the AC network via a rectifier (3) at one side and via individual diode pairs (1.14, 1.15 - 5.14, 5.15) to the intermediate DC circuit capacitor at the other side. The voltage across the auxiliary capacitor is compared with a reference voltage to operate the brake switch when the reference voltage is exceed. ADVANTAGE - Provides common dynamic braking of all AC motors without overvoltages in intermediate DC circuits.

Title: Catalytic gas and air mixture burner - has catalyst-coated combustion gap heat sealed from water space by air gap
Inventor: FAUST HANS-JOACHIM DIPL ING
IPC: F24H1/00
Filed: 1993-03-04
Granted: 1994-03-03
Abstract: A burner catalytically combusts gas and air mixtures via a catalytically coated combustion gap. The gap is heat sealed from the water space by means of an air gap (5) which is flowed by the combustion air (L) between combustion gap (3) and water space (1). If the space (1) is vertical, the air gap is flowed downstream by the combustion air for preheating so that the air mixes in the lower zone (6) with the fuel gas (B) and in so doing preheats the gas. In detail, the catalytic coating (2) in space (1) forms the first combustion stage in the combustion gap (3), using as second stage the monolithic burner itself (4). Fuel gas rises into gap (3) and combustion air descends via gap (5) for preheating and so acts as seal between water space (1) and the combustion gap (3). The mixture rises through gap (3) to react with the catalyst 92) prior to total burn in the burner (4). USE/ADVANTAGE - Water heaters. Air gap as seal between water space and combustion gas also preheats combustion air and fuel gas for total combustion.

Abstract: FIELD: mining industry, sealing of drill string-borehole annulus in oil and gas wells. SUBSTANCE: packer has body 1 with sealing member 2, sleeve 3, end piece 5, powder charge 6 with electric initiating unit and stop unit. External surface of end piece 5 has annular recess forming with sleeve 3 the airtight chamber filled with labelling substance 11. Packer is lowered into well on the pipe string. Using radiation logging instrument lowered on a cable into pipe string, background diagram is taken on which position of labelling substance 11 in packer is fixed. Then, cable inductor is lowered and packer electric initiating unit is actuated. Under the action of pressure of powder gases of charge 6, sleeve 3 compresses sealing member 2 and opens airtight chimaera with labelling substance 11 which is mixed with well mud In this case, stop unit keeps sealing member is compressed position. In case of unreliable packing, labelling substance appears on the other side of sealing member whose presence is registered on the diagram when the radiation logging instrument is lowered again in the well, that is indicative of the packer service conditions. EFFECT: higher reliability in checking the packing tightness.

Title: Method of delignification and bleaching of cellulose
Inventor: LENNART ANDERSSON
IPC: D21C9/153
Filed: 1992-04-29
Granted: 1997-01-10
Abstract: The present invention relates to a process for delignification and bleaching of chemically digested lignocellulose-containing pulp, where the pulp, from which essentially no magnesium ions have been removed by acid wash, is treated with a complexing agent at a pH in the range from 4 up to 9.0, whereupon the pulp is bleached with ozone. The initial treatment with a complexing agent removes the ions of certain metals detrimental to the subsequent ozone bleaching, while retaining in the pulp the desirable ions, primarily of alkaline earth metals. Thereby, the selectivity in the delignification is increased and the strength of the pulp maintained. The pulp can be bleached with peroxide after the treatment according to the invention, to obtain the desired final brightness and completely avoid formation and discharge of chlorinated organic compounds.
