Patent SE-8605347-D0 (SE)
IPC: G05F1/44
Filed: 1986-12-12
Abstract: The primary (10) and secondary (11) windings of the transformer are nominally dimensioned for the lowest nominal mains voltage level occurring. In order to regulate at all times the current pattern in the primary winding at a level which ensures that the required output voltage is received from the secondary winding over appropriate terminals (13,14) with a thyristor (15) incorporated in the primary winding. - The thyristor obtains its ignition voltage from the output terminals, the voltage is stabilised form occurring over a capacitance (16) on the output from a rectifier (17) connected to a secondary circuit. The output voltage monitored on leads (18,19) has a constant dimension, i.e. is not allowed to increase or diminish since any tendencies in the leads bring about an immediate adjustment of the ignition time point for the thyristor.

Abstract: The rotor is of dynamo plate or other conductive material, and the stator poles are of material with similar magnetic properties, each pole being enclosed by a concentric magnetising winding. There is an even number of stator poles, equal to the number of rotor poles, and the rotor pole width is approx. half the distribution of the stator poles. The stator poles have tracks with even or uneven distribution. A three-phase system is only obtained with connected windings which have track stages approx. the same as the pole distribution, and in a twin-poled generator with even slot distribution, the number of slots per pole is two, as is the number of windings. A symmetrical three-phase system is obtained where the adjacent outputs (B1,B2) of the two windings in the one stator pole are joined to the output (R) of the three-phase system. The second and third outputs (S,T) of the system comprise the adjacent winding ends (S1,S2) of the other pole.

Abstract: The invention relates to a tubular pole 1. The rigidity thereof is maintained by static interaction between at least two elements disposed at different radial centre distances and forming part of the pole. As a result of local stress in the transverse direction of the pole 1, the said static interaction is brought to an end. The result is that the pole collapses. According to the invention, the said elements are layers 4,5,6 in a laminate material which forms the wall of the tubular pole 1. The pole 1 has been given a local region A in which the said static interaction is weakened by a delamination tendency of the layers 4,5,6 which is enhanced relative to rest of the pole. When the pole 1 is subjected to transverse forces in the region A, it collapses here but remains otherwise intact. <IMAGE>

Abstract: Described is an esterification process for the preparation of esters from carboxylic acids and lower alkanols, in which the alkanol is added to the reaction mixture beneath its surface and the temperature of the reaction mixture is kept above the boiling point of water. By shifting the reaction equilibrium towards the formation of ester, the process allows a high reaction rate of carboxylic acid to ester, requires less alkanol than conventional processes and dispenses with the necessity of azeotrope-like solvents or other dehydrating agents during the reaction.

Such a network (300) consists of the original circuit and the alternate circuits: the original circuit, which are the nodes (202-212) having links (214-222) between them; the alternate circuits, which are nodes (302, 306 and 304) having alternate links (308-314 and 316, 318) between them. Each node in the network has incoming/outgoing burst detectors and arbiters controlling the node.
