IPC: B23D21/14

Abstract: An apparatus for cutting hollow, metal, spirally formed pipes is disclosed. The apparatus uses two passive, rotatable knife blades to cut the pipe. An upper knife blade is positioned inside the pipe so that its cutting edge is adjacent to the inner pipe surface. A lower knife blade is positioned outside of the pipe so that its cutting edge is adjacent to the cutting edge of the upper knife blade in the lateral direction, but is clear of the pipe and upper knife blade in the longitudinal direction. To cut the pipe the lower knife blade is raised until its cutting edge overlaps the cutting edge of the upper knife blade. The knife blades then puncture the pipe. The pipe is rotated through the overlapping blades to completely cut the pipe. Since the pipe moves spirally (i.e., it moves forward while it rotates), the knife blades are adapted to move in the direction of the pipe during the cutting process. This permits the overlapping knife blades to cut the pipe rectangularly. The upper knife blade is attached to a cantilevered boom, and the lower knife blade is attached to a knife holder and a vertical raising device. These components are all attached to sliding guide rails so that they move with the cutting blades in the direction of the moving pipe during the cutting process.

Abstract: A voltage converter provided for use in power electronics, particularly as an inverter for generating alternating voltages for vehicle motors. Electric energy is supplied to the converter via direct-voltage connections (2, 3). The desired alternating voltage can be tapped off at an alternating-voltage connection (1). The alternating-voltage connection (1) is connected via at least one of series connected gate turn-off thyristors (Th1, Th2) and via at least one current limiting reactor (L1), which is connected in series with the gate turn-off thyristors to respective of the positive and negative direct-voltage connection (2, 3). Each gate turn-off thyristor is provided with a turn-off relief circuit (5). In parallel with the current limiting reactor, a reactor free-wheeling diode (D1) is connected in series with a reactor free-wheeling resistor (R1) in a free-wheeling branch. To reduce overvoltages during the turning-off of the gate turn-off thyristors, which overvoltages originate from stray inductances in the feed lines, an overvoltage capacitor is connected in parallel with these thyristors via the reactor free-wheeling diode.

Abstract: A method for the conversion of C₃ and C₄ hydrocarbons to less saturated hydrocarbons, such as ethylene and propylene and particularly ethylene, includes contacting the feed hydrocarbons with mixed oxides comprising a major proportion of magnesium and a minor proportion of manganese, preferably under conditions which selectively convert the feed hydrocarbons to ethylene and ethane and particularly ethylene, including a temperature between about 625°C and 850°C. The method is preferably carried out in the presence of steam at a mole ratio of steam/hydrocarbon of less than about 10:1. Selectivity to ethylene and ethane and particularly ethylene is improved and the life of the catalyst, during which the desired selectivity is attained, is extended by adding a promoting amount of at least one oxide of calcium, barium, strontium, tin and antimony. Further improvement can be obtained by limiting the amount of bound or fixed sulfur in the catalyst.

Abstract: For some applications of slide layers, for example in connecting rod bearings of internal combustion engines, for individual sites of a formed piece, high load bearing capability are required while for other places of the same formed piece good embedding abilities are demanded. A composite material with a slide layer applied by cathode sputtering of a tightly cohesive matrix and an insoluble component distributed statistically in it, is adapted to these opposite demands in that the diameter of the particle of the insoluble material has gradients at predetermined sites, which extend parallel to the surface of the slide layer, and to which slide layer hardness gradients correspond. These gradients are generated during the cathode sputtering process in the substrate to be coated to form a growing slide layer having temperature gradients which are maintained and which extend parallel to the substrate surface.

Abstract: Scale-forming metal oxides and carbonates, such as cupric oxide, can be precipitated from an ammonical leaching solution with minimum scale build-up by evaporating the solution in an externally heated rotary drum (16). The rotary drum includes a plurality of axially spaced annular baffles (80) defining a plurality of compartments (84-100) containing a tumbling medium (140), such as spherical balls. The solution (108) is continuously introduced into the inlet end (58) of the rotary drum (16) and heated under pressure to a temperature above its boiling point as it flows over the baffles (80) toward the outlet end (60) of the rotary drum. A slurry containing the precipitated cupric oxide is continuously withdrawn from the outlet end (60). Vapor and gases are continuously withdrawn from the inlet end (58). The balls (140) rub against each other, the interior of the rotary drum (16), and the sides of the baffles (80), as the drum is rotated at a non-centrifuging speed, to provide a grinding or scrubbing action which minimizes a scale build-up of the precipitating cupric oxide.

Abstract: A grinding method for profiled parts, in particular turbine blades, blades manufactured accordingly and also typical associated intermediate products. In order to reduce the number of operations during manufacture and to make possible efficient production, the contours of base (2), head (3) and convex suction side (4) of a turbine blade are manufactured by deep grinding in one clamping set-up. A blank suitable for this machining has at its ends residual pieces (8, 9) which are used for the clamping and are cut off later. The entire blade contour with the exception of the pressure side is manufactured by rotation and translation of the blank relative to a rapidly rotating grinding wheel. In order to ensure an efficient grinding operation, the volume of metal removed per unit of time follows a predeterminable function during the pre-forming, which function can also be constant if need be. This possibly location-dependent and/or time-dependent function of the volume of metal removed per unit of time takes into account the heat dissipation in the workpiece in the vicinity of the respective grinding point in order to avoid thermal stresses in the surface layer. Finally, the final contour and surface finish is obtained during finish-grinding in the same clamping set-up.
