Abstract: The invention relates to a method for separating and/or enriching prokaryotic DNA, comprising the following steps: a) contacting of at least one prokaryotic DNA that is in solution with a protein that bonds specifically to prokaryotic DNA, the protein being 25%-35% homologous with the wild-type CGPB protein, thus forming a protein-DNA complex; and b) separation of the complex. The invention also relates to a kit for carrying out said method.

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.

Abstract: A device for grinding an end face at an edge of a workpiece bore of a workpiece has a driven grinding tool and a guide pin, connected to the grinding tool, for insertion into the workpiece. 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.
