Title: Automatic lubricator device for crystal-syrup mixture (masacocida) and the utilization process thereof.
Inventor: ROBERTO SIGALA VARGAS
Filed: 2003-11-12
Abstract: A lubricator device for a crystal-syrup mixture (masacocida) presenting a novel and improved option for preparing the crystal-syrup mixture before the purging thereof during continuous centrifugal processes. The purpose of the invention is to avoid the dissolution of sugar crystals, which is caused by heating and water addition for reducing the crystallized syrup viscosity in the mixture to be centrifuged. The compact design of the disclosure facilitates the location thereof in the available spaces of the sugar refinery facilities without the need of modifying the current installations. The lubricator device increases the purge capacity in the centrifugal machines from about 30% to 40%, and further recovers sucrose, which previously was mixed together with the final crystallized syrup, by means of avoiding sugar crystals to dissolve partially due to the preparation of the crystal-syrup mixture, before the centrifugation thereof. The automatic control of the disclosure makes possible t o obtain of reliable results.

Title: Synchronous machine.
Inventor: ALOYS WOBBEN
IPC: G01R31/02
Filed: 2002-06-06
Abstract: The invention relates to a synchronous machine, preferably comprising salient poles with pole windings that are galvanically interconnected. The invention further relates to a wind energy plant and to a method for monitoring the synchronous machine of a wind energy plant. The aim of the invention is to improve a synchronous machine and a method for operating such a synchronous machine in such a manner that the fire risk is reduced. To this end, the synchronous machine has an armature (rotor) with a plurality of poles that are each provided with at least one pole winding, the pole windings of several poles being galvanically interconnected by means of a conductor through which an energizing current flows. The inventive machine is specifically characterized in that a monitoring conductor is mounted substantially parallel relative to the first conductor, whereby said monitoring conductor is or can be impinged with a predetermined signal. The monitoring conductor is further coupled to or linked with a device that detects the signal. An interruption of the first conductor is or can be detected as a result of the signal modification in the monitoring conductor. The device for detecting the signal is coupled to a control device that at least reduces, preferably disconnects the energizing current flowing through the first conductor.

Title: Method of manufacturing an elasticized composite material.
Inventor: LARRY KENNETH JOHNSON
IPC: A61F13/49
Filed: 2002-11-14
Abstract: A method of manufacturing an elasticized composite material including a multiplicity of elastic strips for use in garments, particularly in disposable absorbent articles is disclosed. The method includes the steps of folding the first substrate around the mandrel to form a tube while moving the tube longitudinally at a first velocity, and simultaneously winding at least one elastic strip around an outer surface of the tube at a second velocity to form a helical path. The elastic strip can be joined to the outer surface of the tube along the helical path to form a first composite tube. The method further includes the step of folding a second substrate around the first composite tube to cover the elastic strip and to form a second composite tube, which then can be slit longitudinally to form a planar composite material. Finally, the planar composite material can be activated to form the elasticized composite material.
