Abstract: The present invention provides a method of starting up a loop reactor system, which method includes heating a reaction mixture present in the loop reactor system with the heat of reaction of at least one exothermic reaction occurring in the loop reactor system. The method of the invention makes possible an inexpensive, reliable and simple start-up of loop reactor systems, since the heat liberated when carrying out an exothermic reaction is utilized for heating the reaction mixture present in the loop reactor. Use of the method of the invention makes it unnecessary to switch heat exchangers over from coolant to heat transfer media such as steam. Since the method of the invention is able to heat up the reaction mixture in the loop reactor system more rapidly than in conventional methods, the number and the amount of by-products formed by secondary reactions during the start-up phase is reduced.

The guide pin is dimensioned so as to precisely match the workpiece bore. The guide pin has a central axis. The grinding tool has a grinding surface extending angularly to the central axis. The grinding tool is periodically displaceable transverse to the central axis.

Abstract: A sinterable mixture comprising iron-containing materials and solid fuel is sintered on a sintering machine; to decrease the rate at which exhaust gas is to be removed and to produce a desirable sinter, a part of the exhaust gas is enriched to an oxygen content of up to 24% by the addition of higher-oxygen gases and is then recirculated as a recycle gas, and exhaust gas is removed as a tail gas from the process only at a rate which corresponds to the rate of the gas which is formed during the sintering process plus the rate of the gas added for enriching plus the rate of inleaked air which has infiltrated from the outside minus the rate of oxygen consumption.

Abstract: The tool for machining bore transitions includes a holder drivable rotatably through at least one rotation, and drivable in an advance stroke and in a return stroke; and a spring wire having at least two resilient arms with overlapping movable free end, the spring wire being bent into a hairpin shape so as to have a stem or bent end portion structured to be inserted and held in the holder and a cutting medium provided on the free ends of the resilient arms for machining the bore transitions. The holder can advantageously be provided with a slot for the stem, threaded bolts which engage between the resilient arms of the spring wire and a spring which spring-loads the side of the spring wire inserted in the slot.

Abstract: A tool for processing holes has a shaft which can be clamped in a drive element for executing a forward stroke into a working position within a hole, a return stroke, and an at least rotating working motion of the tool, two support elements arranged on the shaft, wires clamped at one end of the shaft between the support elements and being sprung bowing away from the shaft in an arc shape, the wires being coated with a cutting medium. One of the support elements is axially adjustable relative to the shaft. The shaft has axially positioned slots distributed on a circumference in two regions axially offset from one another. The shaft also has an axial hole leading out from both ends of the shaft and extending into the regions. The support elements are formed as limit stops inserted in the axial hole and each end just short of an entry of the hole into an area of the slots. The wires have ends extending through the slots and coming to rest on the limit stops.

Abstract: A magnetic chuck assembly comprises top and bottom plates separated by a layer of non-magnetizable material, each plate having magnetizable sections separated by strips of non-magnetic material. A rotor mounted between the top and bottom plates carries a plurality of permanent magnets substantially symmetrically disposed therein. The magnets in each half of the rotor are of the same polarity but those in one half are of opposite polarity to those in the other. When the rotor is turned to a position in which all the magnets of like polarity in one half thereof lie between the magnetizable sections of the plates on the same side of the non-magnetizable strips, the sections become magnetized and hold a magnetizable workpiece in place on the edges of the plate. Switching the rotor to a position in which equal numbers of magnets of opposite polarity lie between the magnetizable sections serves to de-energize the latter and release the workpiece.

Abstract: A pressure valve, which is installed in the delivery line leading from a fuel injection pump to a fuel injection valve, and which has a valve closing member opening in the direction of delivery, which is provided with a return collar. To achieve uniform injection, particularly a uniform curve of injection at a given load plotted against the speed, the opening rate of the connecting cross-section at the valve closing member is controlled by the guide part being provided immediately adjacent to the return collar, which guide part has three excisions at its circumference. These excisions are bounded by a flow channel guiding the valve closing member and have a defined flow cross-section of equal size, which in total is of the order of magnitude of the cross-section of the delivery line.

Abstract: The process for cleaning collecting surfaces of dedusting electrostatic precipitators includes the steps of introducing a coarse-grained cleaning dust into the dedusting electrostatic precipitator, collecting at least the cleaning dust electrostatically in the dedusting electrostatic precipitator and periodically removing the cleaning dust so collected from the collecting surfaces to form a collected dust. To provide a more complete cleaning, the cleaning dust is fed into a gas-flowless space above the fields containing the collecting electrodes and the cleaning dust is distributed in the gas-flowless space according to the cleaning requirements. An apparatus for performing the above cleaning process is also described.

Abstract: A process and apparatus are used for purifying dust- and pollutant-containing exhaust gases, which are first subjected in a first stage to a dry purification in a mass separator and are subsequently subjected in a second stage to an electrostatic purification in an electrostatic precipitator. In the second stage the exhaust gases are passed through one or more fields provided with liquid-wetted collecting electrodes, which define gas passages. The electrostatic precipitator also has an overflow trough and a collecting trough for each collecting electrode. Liquid supplied to the overflow trough flows onto the collecting electrode and then is collected in the collecting trough.

Abstract: A process and an apparatus for the electrostatic purification of dust- and pollutant-containing exhaust gases in multiple-field precipitators are proposed. The exhaust gases are first subjected in a first stage to an electrostatic purification under dry conditions in gas passages defined by platelike collecting electrodes and are subsequently passed in a second stage through one or more fields defined by liquid-wetted collecting electrodes, which define gas passages. The liquid which is supplied in the second stage at the top ends of the collecting electrodes is laterally discharged from the precipitator and the substantially dry dust which is still collected in the second stage is fed to dust-receiving means.

Abstract: The separation rate of electrostatic precipitators associated with sintering plants is improved in that the exhaust gas is conditioned by means of solid particles. For that purpose, part of the coke breeze as a fuel for the sintering process is branched off, separately ground, supplied to the exhaust gases to be dedusted, collected together with the dust in the electrostatic precipitators and returned to the sintering process.

Abstract: A package for photoresist material, particularly a dry resist, is substantially impermeable to water vapor, thereby preventing humidity-related effects which adversely influence the processability of the photoresist. The package can comprise a film tubing, the ends of which are closed by welding or gluing, into which a photoresist roll is placed. As the material for the film tubing, a composite material can be used which is formed of a polyester film as the support film, to which an aluminum foil is laminated or which is vacuum-metallized with aluminum and a polyethylene film laminated on top. A tinplate container can also be used as a package, the container being closed by soldering after placing the photoresist material inside the container. These packages generally have a permeability to water vapor of less than 0.01 gram of water vapor per square meter per day, at a humidity gradient of 97% and an ambient temperature of 23.degree. C.

Abstract: When collecting electrode walls are cleaned by rapping blows, a discharge of dust is prevented in that the aligned collecting electrode walls which are arranged one behind the other in the direction of gas flow are cleaned at the same time in all fields, the associated gas passages on opposite sides are shut off at the same time and an entraining gas stream is caused to produce in said gas passages a gas flow which is opposite to the normal direction of gas flow.

Abstract: A slot closure for the semi-closed slots of the stator of an electric machine is disclosed. The slot closure comprises slot closing bars interconnected in a ladder-like arrangement by flexible strips. Flexing of the strips by about 90.degree. correspondingly rotates individual bars and permits them to be successively inserted edge-wise through the slot openings. Advantageously, the ladder-like arrangement of bars and strips is made of a moldable or stampable material.
