Abstract: Individual laminas (14) are blanked from sheet strip material 12) and stacked to form a lamina stack (16) for use in electric motor or generator rotors or stators. The thickness of each lamina (14) is measured prior to stacking, and the individual lamina thickness measurements (37) are supplied to a controller (30). The controller (30) monitors the increase in stack height as the individual laminas (14) are stacked and compares the increase in stack height to an operator entered preselected stack height. Individual laminas (14) are stacked as long as the height of the lamina stack (16) is less than an operator entered preselected stack height. Individual laminas (14) are continually stacked until the addition of another lamina would cause the lamina stack height to exceed the preselected stack height. Slotted openings (28) are blanked in each lamina (14) to form a slot in the stacked laminas which is skewed to the stack axis by a constant skew angle by providing that the lamina stack (16) is rotated an angular increment determined by the thickness of the lamina (14) prior to stacking the lamina (14).

Title: Messaufnehmer für Längen- oder Abstandsänderungen, insbesondere für berührungslose Messung von Drehmomenten an rotierenden Wellen
Inventor: DOEMENS GUNTER DR
IPC: G01L3/10
Filed: 1989-07-17
Abstract: Bei einem Meßaufnehmer für Längen- oder Abstandsänderungen (Δ x) mit mechanisch-elektrischer Meßgrößenumformung ist als verstellbare Kapazität eine Kondensatoranordnung (Ka) mit zwei parallel zueinander verstellbaren Elektrodenstrukturen (Es1,Es2) vorgesehen. Die vorzugsweise kammförmig ausgebildeten und ineinandergreifenden Elektrodenstrukturen (Es1,Es2) bestehen jeweils aus mehreren ebenen, parallel im Abstand zueinander angeordneten Elektroden (E1,E2) die paarweise einander zugeordnet sind. Durch eine stark unsymmetrische Anordnung der Elektrodenstrukturen (Es1,Es2) wird eine kapazitive Entkoppelung erreicht, so daß die Gesamtkapazität der Kondensatoranordnung sich aus einer Parallelschaltung von Elektrodenpaaren ergibt, die jeweils durch einander zugeordnete Elektroden (E1 und E2) gebildet sind. Als Meßgröße dient die durch den variablen Elektrodenabstand (d1) der Elektrodenpaare hervorgerufene Kapazitätsänderung. Mit als Mikrostrukturen ausgebildeten Elektrodenstrukturen können beispielsweise Torsionen (Δ x) von wenigen Mikrometern erfaßt werden. Um den Einfluß von auf die Welle (We) einwirkenden Querkräften oder Biegemomenten zu kompensieren, ist der Kondensatoranordnung (Ka) vorzugsweise eine zweite, in bezug auf die Achse (A) der Welle (We) um einen Winkel von 180° verdreht angeorndete, identische Kondensatoranordnung zugeordnet, wobei die Meßkapazität durch eine Reihenschaltung der Gesamtkapazitäten der beiden Kondensatoranordnungen (Ka) gebildet ist.

Abstract: In an ISDN network, terminals connected to an S-bus (4) are fed  via  this S-bus (4) by a d.c. supply arrangement (6, 7, 20). The d.c. supply arrangement comprises a main supply unit (7) and an emergency supply unit (6) which are coupled with opposite polarity to the S-bus (4)  via  a coupling circuit (20). Consequently, the emergency supply unit (6) needs to supply only those terminals which are also made suitable for voltages with opposite polarity, and which generally present only elementary telecommunications functions. 
     A mechanical change-over switch forming the coupling circuit (20) has, in addition to the widely known drawbacks of mechanical switches, a further drawback that it requires a long supply line if the two supply units (6, 7) are to be positioned at a large relative distance. 
     An electrically arranged coupling circuit (20) does not present these drawbacks and, besides, has additional advantages such as current limiting and a readily realizable monitoring of the value of the output voltage.

Abstract: In a liquid crystal display, the electrodes (E) in strip form are arranged alternately and on interstices in a plurality of superimposed layers (US, OS). This eliminates the uncontrollable surface sections present in conventional liquid crystal displays which originate from the spaces necessary for electrical insulation between the individual electrodes (E) lying in one plane. Image resolution and contrast are enhanced. Other advantages result from the bonding of the electrodes, which are less compactly arranged in the individual layers (US, OS).

Abstract: A magnetic separation apparatus is described, which is prima­rily intended for separating magnetic particals contained in a fluid. Such apparatus is primarily used in the process of sewage purification by binding magnetic particals to the sub­stance to be removed, and by applying a magnetic filter. The invention resides in the fact that the channel for supplying the liquid to be treated has such a shape that part of the substance to be separated already precipitates before rea­ching the actual magnetic filter (9). This avoid the quick fil­ling of the magnetic filter (9) thus extending periods between rinsing the filter. By applying a relatively weak field in the area (8 and 25) in wich precipitation takes place, precipitation is enhanced.
