Title: Elektromechanische Bremse mit Selbstverstärkung
Inventor: DIETRICH JOHANNES
IPC: F16D55/48
Filed: 1998-04-30
Abstract: Eine insbesondere für Fahrzeuge geeignete elektromagnetische Bremse hat einen elektrischen Aktuator, der eine Betätigungskraft erzeugt und auf zumindest ein Reibglied wirkt, um dieses zum Hervorrufen einer Reibkraft gegen ein drehbares, abzubremsendes Bauteil der Bremse zu drücken. Um die vom Aktuator aufzubringende Betätigungskraft niedrig zu halten, ist zwischen dem abzubremsenden Bauteil und dem elektrischen Aktuator eine Anordnung vorhanden, die zur Selbstverstärkung der vom elektrischen Aktuator erzeugten Betätigungskraft führt. Eine Einrichtung zum Vergleichen eines Sollwertes der Reibkraft mit dem Istwert der Reibkraft steuert bei einer Abweichung zwischen Sollwert und Istwert den elektrischen Aktuator zum entsprechenden Erhöhen oder Verringern der erzeugten Betätigungskraft an, so daß der Istwert dem Sollwert der Reibkraft angeglichen wird. Reibwertschwankungen wirken sich somit nicht störend aus.
Patent DE-19820032-A1 (DE)
Inventor: SCHWARZKOPF KAY
IPC: A23L5/20
Filed: 1998-05-05
Abstract: The invention relates to a method for removing cholesterol from liquid and dried egg yolk, which makes it possible to obtain liquid egg yolk, liquid whole egg, dried egg yolk or dried whole egg with a significantly reduced cholesterol content. Starting with the liquid or dried egg yolk, the lipid constituents and cholesterol are separated from the solid by extraction using an organic solvent. The cholesterol is separated from the lipid phase by a selective adsorbent on a saponine basis which is bound to an inorganic carrier. By combining the lipid fraction freed of cholesterol and extracting agent with the proteins freed of extracting agent and then homogenizing same with addition of water and/or dried egg white and/or liquid egg white, liquid egg yolk or liquid whole egg is obtained which is largely free of cholesterol and can be spray-dried.

Title: Multifilament high temperature superconductor strip production, having interior matrix regions of higher hardness
Inventor: KAUTZ STEFAN
IPC: H01L39/24
Filed: 1998-07-03
Abstract: A multifilament high temperature superconductor strip production process comprises annealing in a reactive gas atmosphere to form a hardening compound, after compaction but before flattening. Production of a multifilament superconductor strip, with several conductor cores of high Tc superconductor metal oxide phase embedded in a normally conducting matrix material, comprises compressive deformation of a superconductor precursor starting material to form a multi-core conductor which is then flattened and annealed to form a strip, the novelty being that, prior to flattening, the conductor is annealed in an atmosphere containing a certain gas component which reacts with one or more alloying elements in the matrix material to form a hardening compound. Preferred Features: The superconductor material is a bismuth cuprate with a 2223 type high Tc phase and the matrix material is silver or a silver alloy. The atmosphere is a nitriding or carburizing atmosphere.
