Abstract: The present invention relates to a method of recovering chemicals from spent liquors while at the same time utilizing energy liberated during the process. The spent liquors are gasified and partially disintegrated in a reactor (1), external thermal energy independent of combustion being simultaneously supplied to the reaction zone (2) of the reactor, after which the resultant melt is separated (at 9) at substantially the temperature prevailing at combustion, the gaseous product thereby formed being quenched in a quenching and cooling zone (6), to a temperature below 950.degree. C. A product gas is thus obtained which contains substantially no sulphur impurities, an alkali product with high sulphide content and an alkali product substantially free from sulphide and having low Na.sub.2 CO.sub.3 content.

Abstract: The invention refers to a seal for bearing spaces, wall channels for shafts and the like, where the seal is fitted to the shaft. The seal is characterized in that it incorporates a sheet metal strutting projecting radially outwards, and on the side facing away from the space intended to be sealed off being equipped with mainly radially extending vanes, the radial extension of which mainly coincide with the radial extension of the sheet metal strutting.

Abstract: In a process for case-hardening rolling bearing elements of low-alloy nickeliferous steel, the rolling bearing elements are carburized in a dissociating carburizing gas, cooled down, heated to hardening temperature, austenitized in the carburized layer and, lastly, quenched.So that no brittleness of the rolling bearing elements takes place upon carburization due to dissociated hydrogen, the bearing elements are cooled from carburizing heat down to about 300.degree. C. in agitated inert gas and then held at this temperature, so that sufficient dissociated hydrogen escapes from the carburized layer of the rolling bearing elements. Subsequent heating of the said elements to hardening temperature or to intermediate annealing temperature is advantageously effected after holding at 300.degree. C.

Abstract: In a drive device for pumps consisting of a pump impeller mounted in a pump chamber, a pump cover covers the pump chamber and has an extension and a bore passing from the pump chamber to the outside. A shaft is connected at its inner end to the pump impeller and at its outer end in a torsion-proof manner by way of a coupling element to a drive wheel. A bearing supports the shaft and drive wheel in the housing bore and extension respectively. The coupling element is formed by an external edge rigidly connected to the drive wheel and covers the outer bearing and the extension laterally on the outside. A cover plate with a center section connects in a torsion-proof manner to the shaft, and is adjusted to elastically adjust the cover plate relative to the pump cover either inward toward the pump chamber or outward away from the pump chamber, thereby providing for automatic adjustment of the radial and axial load-supporting bearings means to remove their play.

Abstract: A method of grinding rough-shaped spherical objects to a finished spherical form comprising the steps of freely supporting the rough-shaped spherical object on one end of a vertically oriented tube. This one end is open and has an inside diameter such that a segment portion of the object lies within the tube. Next, an abrasive is applied to the surface of the object, and the object is ground by vibrating the tube axially at a frequency in the range of approximatelly 20-25 KHz, whereby the surface of the object is ground to a truer spherical shape.

These assemblies have a common centerline, and the rotary assembly comprise the rotor and the stationary assembly the stator, located concentrically inside the rotor, of an electric motor. The rotatable assembly is mounted rotatable relative to the stationary assembly by means of a tubular member extending coaxially with the centerline and a shaft located therewithin. Two bearings are located at a distance one above the other and are mounted between the shaft and the tubular member, at least one of which bearings comprises a rolling bearing. The other one of the two bearings comprises a journal bearing.

Abstract: A bearing assembly comprises a housing, a bearing and a shaft. Reaction to a radial load includes substantial components to each side of the radial load line and opposing each other. These components laterally stabilize the bearing. These reaction components arise because the assembly has an arcuate less stiff portion in line with the radial load line.

Abstract: To regulate the speed of a plurality of asynchronous motors fed by a converter having a variable output frequency and output voltage and having a load-dependent slip, particularly asynchronous motors for driving spindles of a textile machine, the rotational frequency of several selected asynchronous motors is measured by means of respective digital frequency indicators. This measurement takes place in continuous repetition, always beginning simultaneously. The pulses of the frequency indicators are counted by means of respective first counters (1-6), all of which release a pulse when they reach the same counter condition. An OR circuit (13-17) connects the counter outputs with a second pulse counter (18) in such a manner that this condition is reached first by the output pulse released by the highest rotational frequency and then by the output pulses released by the second-highest rotational frequency, etc.

Abstract: Two springs inserted in series, which press a tension roller against a drive belt, are provided in a tension device for a drive belt. The tension spring essentially effects adjustment of the tension roller during assembly and after that effectively is inoperative. The working spring is active during operation and within a limited range of adjustment of the tension roller. The tensions of the two springs are designed so that during assembly equilibrium of forces exists at a middle working point within the path of adjustment. These features result in a simple and precise adjustment during assembly.

Abstract: A method for assembling bearing rings in an elongated sleeve member consisting of the steps of forming a roller shell with three sections of varying wall thicknesses separated by angular circumferentially extending shoulders, deforming the shoulder between the middle section and one end section to form a ring-shaped radially, inwardly directed projection by axial displacement of the shoulder. A bearing ring is inserted in the interior of the shell member so that one axial end face engages the first radially oriented projection formed and deforming the shoulder between the middle section and the other end section to form a second radially inwardly directed projection by axial displacement of the shoulder which confronts the opposite axial end face of the bearing ring.

Abstract: A device for measuring the effective viscosity of a lubricant in which a motor rotates one element of a bearing with respect to the other, the lubricant being supplied to the bearing. The bearing is part of a sensor that outputs a signal corresponding to the percentage of contact time between the elements of the bearing. A speed regulator for the motor is responsive to the output of the sensor to maintain the speed of relative movement so that no roughness contacts occur in the bearing, at which time the motor speed is a measure of viscosity.

A third plane extends perpendicular to the axis. The angle is between the first and third planes. .mu. is the coefficient of friction between the element and the bore or shaft.
