Title: Process of making fine ceramic powders from aqueous suspensions
Inventor: KIRCHNEROVA JITKA
IPC: C01G37/00
Filed: 1997-06-10
Abstract: The new preparation process for making fine high specific surface ceramic powders suitable as catalysts or precursors for ceramics uses lanthanum (or other rare earth lanthanide) oxide as one of the precursors. The oxide is mixed with water to form a liquid slurry, whereby it is transformed to the hydroxide by reaction with water. The resulting hydroxide slurry, which can be milled to reduce the particle size and to speed up the reaction, is then combined, while stirring vigorously to assure homogenous mixing, with a solution of required amount of remaining metal nitrate precursors, for example strontium and cobalt nitrates. The reaction between lanthanum hydroxide and transition metal nitrates produces a coloured (colour depending on the transition metal) slurry consisting of metal hydroxides suspended in aqueous nitrate solution with pH > 2. This perovskite precursor slurry is spray-frozen and freeze dried. The freeze-dried material is transformed to perovskite by slow controlled calcination at temperatures above 550 ~C. For example calcination 12 h at 585 ~C and subsequently 4 h at 620 ~C produces nearly phase pure perovskite having specific surface area of > 10 m2/g, depending on the composition. The perovskite precursor slurry can alternatively be processed first by spray-drying (instead of spray-freezing/freeze-drying) and subsequent calcination.

Inventor: FISCH EBERHARD H
IPC: H04N19/625
Filed: 1990-06-01
Abstract: ABSTRACT:      Method and apparatus for digitally processing a high definition television augmentation signal.      A method and apparatus for digital encoding are described for compressing the augmentation channel signals (chrominance and luminance signals for panel information and high frequency luminance and line difference signal) so that this information can be transmitted in a 3 MHz wide RF channel using a digital transmission scheme such as QPSK. Analog signal components are sampled and converted to digital signals. Each of the signals is fed into a separate coder which reduces the number of bits/pixel required to reconstruct the original signal. Compression is achieved by quantization and removal of redundancy. The compression scheme is based on the use of DCT together with VLC. Each augmen-tation signal has its own coder, which is adapted to the unique statistics of this signal.

Title: Composite materials and methods for making the same
Inventor: SCHIROKY GERHARD HANS
IPC: C04B35/628
Filed: 1998-10-26
Abstract: The present invention generally relates to mechanisms for preventing undesirable oxidation (i.e., oxidation protection mechanisms) in composite bodies. The oxidation protection mechanisms include getterer materials which are added to the composite body which gather or scavenge undesirable oxidants which may enter the composite body. The getterer materials may be placed into at least a portion of the composite body such that any undesirable oxidant approaching, for example, a fiber reinforcement, would be scavenged by (e.g., reacted with) the getterer. The getterer material(s) may form at least one compound which acts as a passivation layer, and/or is able to move by bulk transport (e.g., by viscous flow as a glassy material) to a crack, and sealing the crack, thereby further enhancing the oxidation protection of the composite body. One or more ceramic filler materials which serve as reinforcements may have a plurality of superimposed coatings thereon, at least one of which coatings may function as or contain an oxidation protection mechanism. Specifically, a coating comprising boron nitride which has been engineered or modified to contain some silicon exhibits improved corrosion resistance, specifically to oxygen and moisture. The coated materials may be useful as reinforcing materials in high performance composites to provide improved mechanical properties such as fracture toughness. The present invention also relates to improved composites which incorporate these materials, and to their methods of manufacture.

Abstract: Un appareil ménagé ( électrique ) servant à brasser les aliments à consistan ce fluide ( sauces, sucre à la crème etc. ) dont il faut cuire dans un chaudron sur la cuisinière en remuant constamment pour éviter que les aliments ne collent au fond. L'appareil consiste en: une plaque à induction magnétique déposée sur le rond de la cuisinière; un contrôleur à s a droite ( avec un interrupteur sur le dessus ); ces deux parties sont reliées par un isolant thermique; un petit vérin ajustable ( en dessous du contrôleur ) s'appuie sur la cuisinière pour équilibrer le poids de ce même contrôleur: l'alimentation se fait par un transformateur mural relié à l'une  des prises de courant standard de la cuisinière. Indépendamment, un agitateur constitué: du suppor t- pivot, celui-ci est fixe; du rotor magnétique comportant des pales d'agitation, celui-ci est libre de rotation. Lors de l'utilisation, la personne n'a qu'à déposer un chaudron non-magnétique standard ( un chaudron dont un aimant n'a pas d'attraction ) sur la plaque. Par la suite déposer les aliments à cuire dans le chaudron et ajouter l'agitateur magnétique vers le centre du chaudron. L'agitateur se centrera de lui-même dû aux forces magnétiques entre la plaque et l'agitateur. Il ne res te plus qu'à appuyer sur l'interrupteur pour que l'agitateur tourne de lui-même. Le principe de base est plutôt simple: un moteur électrique dans le contrôleur entraîne en rotation un système d'aiman ts dans la plaque, qui par des forces magnétiques ( à travers le chaudron ), entraîne un autre système d'aimants emprisonné dans le rotor magnétique qui, par des pales, agitent les aliments à cuire da ns le chaudron. La chaleur est fournie par le rond de la cuisinière, la plaque à induction magnétique fabriquée d'aluminium transfert bien la chaleur au chaudron.
