Patent EP-0496096-A1 (EP)
Inventor: HEDDEN KURT PROF DR
IPC: B01D53/86
Filed: 1992-01-01
Abstract: A process is described for removing nitrogen oxides from an exhaust gas by selective reduction with ammonia in a catalyst zone, exhaust gas and ammonia flowing through the catalyst in one direction in one process section and in the opposite direction in a later process section, the ammonia being only fed at intervals, the exhaust gas flow direction being reversed prior to the exit of ammonia at the catalyst end and the process steps mentioned being alternately repeated. The process is characterised in that the site of entry of ammonia into the catalyst is arranged after the site of entry of the exhaust gas. This effects a high NO conversion without ammonia slip. <IMAGE>

Abstract: In order to secure the end of roving (5) on cops (9) on removal from a fly frame it is proposed initially to lower cop carriage (2) to a position such as to bring the top end of bobbins (4) to the height of compressor (16) of flyers (6), then to rotate cops (9) a few turns to wind roving (5) into a groove (17) or onto a roughened or similar surface of bobbins (4) capable of retaining roving (5), after which carriage (2) is further lowered or inclined to cause roving (5) to snap in the section between the end of bobbins (4) and flyers (6). Preferably, before lowering cops (9), a reserve of roving (5) is created by slowly rotating flyers (6) and cops (9) for a few turns with no supply, simultaneously imparting a twist to roving (5) and strengthening it.

Abstract: Method and apparatus for carrying out the  in   situ  inspection of the shaft of a pump. A spacer coupling or link is manually removed from a limited access area intermediate the pump drive and top of the pump shaft. Inspection then is carried out through a previously formed inspection bore extending concentrically along the interior of the shaft. A probe supported by an extension assembly is lowered into the inspection bore until characterizable portions of the shaft such as a labyrinth seal region are identified. A discrete small region of interest which will initially evidence any fault condition then is surveyed with a raster scan movement of the inspection probe. Lower components of the region of interest are also identified by a next adjacent characterizable region such as a fillet welding for a journal assembly. Because of the limited longitudinal extent of the region of interest, the raster type movement of the probe becomes available. A calibration mock-up of the shaft is employed to provide ultrasonic signal readout information to apprise the operator of the presence of characterizable regions and the effectiveness of inspection transducer operation.

Inventor: BELLAMY NORMAN WEST
IPC: F03B13/08

Abstract: The low head energy in for example a river flow is used to provide electrical energy by directing the water through a duct (70), and by inducing air into the duct to create an air flow which is drawn over an air turbine (76) to excite same, and thereby produce electrical energy. The air can be introduced into the flowing water in the duct by a switching arrangement to ensure that no bubbles or pockets of air travel along with the water, which impaires efficiency. The duct may be in the shape of an anti-gravity course (70) to prevent the bubbles from travelling.

Abstract: A method for manufacturing a single focus collimator in a high precision without increasing a cost for manufacturing. In this method, grooves are on a bulk block member first, and a metallic material having sufficient γ ray shielding property such as lead is casted into the grooves formed on the bulk block member, and then the bulk block member with the metallic material casted into the grooves is immersed into a solvent capable of dissolving the bulk block member but not the metallic material, such that a collimator body formed by the metallic material in a shape of the grooves is obtained as the bulk block member is dissolved by the solvent. The sensitivity of the single focus collimator can be made substantially uniform over the entire effective view field by forming the grooves with such intervals that holes formed on the collimator body have larger size toward a center of the collimator body.

Abstract: A known electrochemical actuator has two electrodes in a gastight expandable housing, which electrodes form a cell and on which reversible electrochemical processes take place when a DC voltage is applied; to be precise, depending on the polarity, either a gas is produced which increases the pressure inside the housing, or gas is decomposed, so that the gas pressure is reduced. The pressure changes can be converted into a movement, via the expandable housing. In order to achieve a higher speed for the movement processes, and a larger actuating force, a plurality of cells which in each case have a solid electrode (10), at least one separator (9) and at least one correspondingly designed multi-layer electrode are accommodated in a single actuator. A plurality of cells can be connected electrically in series, and a plurality of series circuits can be connected in parallel to a DC voltage source. For the electrochemical processes to take place, a different DC voltage must be set in each case for the possible types of wiring (in series or parallel). <IMAGE>

Abstract: Color bleed (the invasion of one color into another on the surface of the print medium) using ink-jet inks is alleviated by employing zwitterionic surfactants (pH-sensitive or pH-insensitive) or ionic or non-ionic amphiphiles. The inks of the invention comprise a vehicle and a dye. The vehicle typically comprises a low viscosity, high boiling point solvent, one or two amphiphiles at concentrations above their critical micelle concentration (cmc), while the dye typically comprises any of the dyes commonly employed in ink-jet printing. The amount of surfactant/amphiphile is described in terms of its critical micelle concentration (cmc), which is a unique value for each amphiphile. Above the cmc, micelles form, which attract the dye molecule and thus control the color bleed. Below the cmc, there is no micelle formation, and thus no control of the color bleed.
