Title: Verfahren zur herstellung vollkeramischer zahnteile mit vorbestimmter raumform mittels elektrophorese
Inventor: WOLZ STEFAN
IPC: A61C13/00
Filed: 2003-10-31
Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung vollkeramischer Zahnteile mit vorbestimmter Raumform mittels Elektrophorese, wobei ein elektrisch leitendes oder leitend gemachtes Plättchen zwischen zwei Stümpfen eines Arbeitsmodelles (10, 20) oder einem Gerüstteil direkt oder mit Abstand angeordnet ist, wobei das Plättchen (30) Bereiche (50, 60) unterschiedlicher elektrischer Leitfähigkeit aufweisen kann. Das Plättchen ist während der Elektrophorese mit dem Pluspol verbunden. Mit diesem Verfahren können sowohl Gerüste für Brücken hergestellt werden, wie auch Verblendmaterial auf Gerüste aufgetragen werden. Durch die geometrische Form der unterschiedlichen Bereiche wird die örtliche Stromstärke und somit der örtliche Materialniederschlag eingestellt, wodurch eine gewünschte Raumform des Niederschlages erzielt wird. Das so hergestellte Zahnteil bedarf daher keiner grossen Nacharbeit mehr, wodurch eine beachtliche Zeitersparnis verbunden ist. Insbesondere erübrigt sich das Auftragen von Verblendmaterial mit einem Pinsel.

Title: Yarn creel supports - with rigid mounting for yarn to pass round brake to shuttleless loom
Inventor: COLSMAN JOACHIM
IPC: D03D47/00
Filed: 1972-10-05

Patent DE-2361003-A1 (DE)
Title: Multiphase stepper motor control circuit - giving rapid build up and decay of field current
Inventor: TIETZE ECKART DIPL ING
IPC: H02P8/14
Filed: 1973-12-07
Abstract: Each field winding is connected to its own controller all under the control of a phase counter. The arrival of a signal via the function generator causes the first switching element to connect a high voltage source to the field winding. The current is thus forced up in line with the function generator requirement. A current dependent signal is fed to a comparator, which has a set reference and limits the field current to the desired maximum value. A further signal from the phase counter, operates the second switching element, which connects a further high voltage source, of opposite polarity, to the field to force the current down again. Blocking diodes and logic circuits ensure the correct sequence of events.
