Abstract: In a procedure for starting an asynchronous motor, transferred voltage increases quickly until a change in the phase shift derivative between applied voltage and the input current is detected. Thereafter the input voltage increases more slowly until the input voltage has reached its total value. A device for execution of this procedure has a current detector (5) for generating a signal representing motor current, a voltage detector (6) for generating a signal representing motor voltage and a phase detector (7) for generating a signal representing the phase difference between motor voltage and motor current. There is also a unit (8) to detect any change exceeding a predetermined value in the said phase difference as well as a unit (8) to upon motor start quickly increase the part of alternating currents half periods, under which the motor is given current until said phase difference change is detected and thereafter said part increases more slowly until the voltage has reached its total value.<IMAGE>

Abstract: A fluid-permeable fibre matrix having a large surface area and a method of making said matrix are described. The fibre matrix is characterised in that its fibres are oriented to a high degree in such a manner that the total matrix fibre length is substantially oriented in a main orientation plane, and that membranes are provided between the fibres. It is recommended that at least 60%, preferably at least 80% of the total fibre length of the matrix deviate by at most about 20° from the main orientation plane. The matrix fibres suitably consist of mineral wool, preferably glass wool, while the membranes consist of a film-forming organic or inorganic material, such as synthetic or natural polymeric materials, glass, metals, ceramics, waxes, fats or oils. The membranes may be impermeable or porous, and active material, such as inorganic catalysts, biocatalysts or adsorbing materials, such as activated carbon and zeolites, may be affixed to or incorporated in the membranes. The fluid-permeable fibre matrix may be produced by arranging the main orientation plane of the original fibre matrix which has no membranes, substantially vertical, whereupon a film-forming liquid, such as gelatin, is supplied to the upper end of the fibre matrix. With suitable values of the viscosity and the surface tension of the film--forming liquid, membranes are formed between the matrix fibres, and these membranes are solidified, for example by polymerisation, evaporation of solvent, or in some other manner.

Abstract: A mixture of sulfuric acid and hydrochloric acid essentially free from dissolved sulfur dioxide to be used in a chlorine dioxide reactor is produced by reacting chlorine and sulfur dioxide in at least two reaction zones. In the bottom of a primary reaction zone the total amount of sulfur dioxide needed for the mixed acid production is introduced in an aqueous mixture of sulfuric and hydrochloric acid containing dissolved chlorine and gaseous chlorine. The sulfur dioxide reacts with chlorine in the aqueous phase to produce sulfuric acid and hydrochloric acid. The mixed acid produced in the primary reaction zone contains dissolved quantities of sulfur dioxide and is forwarded to a secondary reaction zone. Chlorine is introduced into the lower part of the secondary reaction zone. The amount introduced can be the total amount of chlorine to be used in the production of the mixed acid for the chlorine dioxide reactor, or it can be a part of that amount, the balance being introduced in the primary reaction zone. The amount should be large enough for a gaseous chlorine phase to leave the secondary reaction zone. The produced mixed acid is withdrawn from the lower part, and preferably the bottom of the secondary reaction zone. At least a part of the mixed acid is introduced into a chlorine dioxide reactor.

Abstract: A process is described for the determination of the aging condition of an exhaust-gas catalyst for an internal combustion engine which is fitted with  lambda -controlled regulation of the fuel/air ratio. In the process, the switching of the fuel/air ratio from rich to lean and vice versa is delayed and the content of the combustibles in the exhaust gas downstream of the catalyst is measured. With delayed switching, complete conversion of the exhaust gas only occurs when the catalyst still possesses its full oxygen-storage capability. Since the oxygen-storage capability decreases with increasing age of the catalyst, the degree of conversion or the proportion of combustible components arising in the exhaust gas when conversion is no longer complete is a direct measure of the aging condition of the catalyst. A catalyst can thus be replaced in good time before it is completely destroyed and before undesired components of the exhaust gas reach the atmosphere.

Abstract: Method for manufacturing form-pressed wood fibre panels, for example door skins, and panels manufactured according to the method. The process starts from a workable, mass produced panel displaying high thermal conductance, for example a so-called MDF-board or chip board. The panel is preheated to a condition where the wood fibres and the binding agent which binds the wood fibres form a pliable or stretchable composition though still in continous panel-like condition. This preheated panel is fed to a form-pressing device where the pressure is relatively slowly increased from 0 to approximately 30 kg/cm<2> during continuing heat supply to a temperature of around 150-200 DEG C. Usually this is attained in connection with door skins after a period of approximately 1,5 minutes. Finally, a form-stable, form-pressed panel is removed from the press.

Inventor: TAKASAKI H
IPC: B62K21/08
Filed: 1991-03-15
Abstract: The degree of damping is determined by a throttling arrangement, via which a medium in the cylinder (8) passes when the piston in the cylinder moves. The piston connecting rod (10), together with the piston, forms a common, integrated unit which with the aid of its location in bearing devices in the cylinder has a resistance to bending. The latter reduces the locking and interference tendencies during the function of the damper, even in the end positions of the piston. The cylinder space is connected to a shunt channel, in which the medium is conducted between the front and rear sides of the piston when the latter moves.

Abstract: In a method for manufacturing a stator for a rotating electric machine, for example an asynchronous machine, which stator comprises a stator core (21) and a tubular housing (1) which at the operating temperature of the machine surrounds the stator core with a shrinkage fit, the manufacture of the housing comprises the following steps. A number of extruded profiles (31, 32, 33, 34), each of which being defined by two edges (345, 346) and comprising a concave smooth limiting surface (341) located between said edges and formed by generatrices along an arc with a radius of curvature substantially corresponding to the external diameter of the stator core, are fixed in relation to each other such that their concave limiting surfaces form a tubular configuration with a predetermined internal diameter. The number and dimension of the profiles between said edges are chosen such that gaps (41, 42, 43, 44) are formed between at least some of their edges when they are fixed to said tubular configuration. Thereafter, the profiles are welded together along their edges into a tubular housing by means of weld joints (51), the width of which is adapted to fill up said gaps.
