Abstract: A corrected torque command value P_TRQ which is produced by correcting a torque command value TRQ with a torque command correcting unit 34 is substantially propor-tional to the armature current of an electric motor. Using the corrected torque command value P_TRQ and its average value P_ATRQ, an inferred temperature change .DELTA.tf of the electric motor is determined in each predetermined cycle time. The inferred temperature change .DELTA.tf calculated in a fuzzy inference operation, for example. The inferred tem-perature change .DELTA.tf is integrated by an integrating unit 37 to determine an accumulated temperature change .DELTA.Tf. The output of the electric motor is limited when the accumulat-ed temperature change .DELTA.Tf exceeds a predetermined value.

Abstract: The invention provides a method for the biological purification of wastewater by means of activated sludge. In a system with an aerated activated sludge tank that is permanently hydraulically connected to at least two sedimentation and recirculation tanks. In the method waste water is introduced into the aerated activated sludge tank and then the waste water is sequentially introduced into the sedimentation and recirculation tanks. A plurality of operating cycles are carried out, with each cycle comprising several phases. In the stirring phase, the wastewater is remixed with activated sludge, which is then allowed to settle during the pre-settling phase and drawing off water clear water in a discharge phase.  Then, reintroducing the settled activated sludge back into the aerated activated sludge tank during the reintroduction phase, which occurs after the pre-settling phase but before the stirring phase. The method operates according to a throughflow principle.

Title: Sprinkler head trigger assembly
Inventor: VOS KENNETH GORDON
IPC: A62C37/12
Filed: 2003-04-14
Granted: 2009-06-23
Abstract: A quick response trigger assembly for an automatic sprinkler head comprises an inherently unstable compression element positioned between the frame of the sprinkler body and sealing assembly. A thermal sensor surrounds the periphery of the compression element and includes at least one heat gathering element positioned a preselected distance from the compression element. The thermal sensor maintains the compression element in compression when the sprinkler head is in the non- activated condition. The presence of a heat gathering member spaced a preselected distance from the compression element increases the surface area through which conduction occurs, and thus, enables the trigger assembly to exhibit sufficient thermal sensitivity necessary to classify the sprinkler head as a quick response. Additionally, the thermal sensor is formed of two or more members which are substantially identical in configuration to thereby decrease manufacturing costs.

Abstract: Il s'agit d'un vibrateur asymétrique fonctionnant à l'air comprimé. Il est placé dans un boîtier doté de deux cavités disposées parallèlement de chaque côté opposé du boîtier. L'une des cavités est plus petite que l'autre. Le piston fonctionnant dans la petite cavité est appelé le piston lent, car il est actionné par de l'air se déplaçant relativement lentement, alors que celui fonctionnant dans la grande cavité est appelé le piston rapide, puisqu'il se déplace plus rapidement quand il est directement entraîné par l'air comprimé. Le déplacement vibratoire asymétrique peut être utilisé pour déplacer des matériaux vers le haut dans les usines ou sur les sites d'assemblage. Les vibrateurs asymétriques à air comprimé nécessitent peu d'entretien et ne comportent pas les risques d'étincelles dus à la présence des câbles d'alimentation électrique des moteurs d'entraînement.

Abstract: The invention relates to a method for cold-rolling strips consisting of, inter alia, special steels and/or nonferrous metals, in a multi-stand tandem rolling mill. The first stand(s) carry out comparatively high reductions and the last stand(s) determine the surface quality of the strip, with a relatively low reduction. The aim of the invention is to improve the capacity of the tandem rolling mill in terms of thickness reduction and in terms of the surface quality of the rolled strips. To this end, an emulsion is used as a coolant and lubricant for the first passages of the strip through the tandem rolling mill with relatively high reduction. The adhesive coolant and lubricant film is then squeezed off the strip following removal from the roll gap of the last emulsion-operated stand. Rolling oil is used as a lubricant for especially the last passage(s) through the tandem rolling mill with relatively low reduction. The invention also relates to an installation for carrying out the inventive method.
