Patent EP-0460726-A1 (EP)
Inventor: MICHELI ADOLPH LOUIS
IPC: C07C53/126
Filed: 1991-05-15
Abstract: Thin films of potassium tantalum niobate, KTa 1-x Nb x O₃, (KTN), material are deposited using the non-vacuum technique of metallorganic deposition. Firstly a suitable metallorganic precursor dissolved in solution, preferably the carboxylates of potassium, tantalum and niobium in xylene, is dispensed onto a substrate much like photoresist. The substrate, preferably platinum or platinum-coated yttria but also foreseeably CaF₂, BaF₂ or Er₂O₃, is spun at a few thousand revolutions per minute to remove the excess fluid, driving off the xylene solvent and uniformly coating the substrate surface with a metallorganic film a few micrometres thick. The soft metallorganic film is then pyrolyzed in an air atmosphere to convert the metallorganic precursors to their constituent oxides, and is subsequently annealed to form a perovskite crystal structure throughout the film. Superior films are formed when the metallorganic precursor solution is potassium-deficient as compared to stoichiometry, and is then subsequently annealed after pyrolysis in a potassium-rich environment to form stoichiometric metal oxide films. The resulting films exhibit uniform, high quality physical, chemical and electrical properties throughout, and are suitable for the economical fabrication of an uncooled infra-red detector having maximum response characteristics.

Abstract: A receiver protector device includes a sealed discharge chamber containing one or more pairs of spaced-apart, conical electrodes and an ionizable gas. A field emission array is mounted in the discharge chamber to provide a source of free electrons which assist in initiating a discharge when an RF input signal exceeds a desired threshold power level. The field emission array includes a substrate, a plurality of generally conical emitters distributed on the substrate, a conductive gate layer for extracting electrons from the emitters and a dielectric layer between the gate layer and the substrate. When a bias voltage is applied to the gate layer, electrons are extracted from the emitters. The field emission array can be mounted adjacent to the electrodes or in a recess in one of the electrodes. The bias voltage can be supplied by a battery mounted on the receiver protector device external to the discharge chamber.

Abstract: By a method for heat treatment of pulverous material, e.g. burning of lime, the lime is first preheated by means of exit gas in a preheater (1, 2, 3) and subsequently burnt in a calciner (4, 14), after which the burnt lime is cooled in a cooler (6, 7). 
     In order to being able to alter the reactivity of the finish-burnt lime, the calciner is divided into two chambers, namely a first chamber (4) in which the lime is burnt at, e.g. 1050 C and a second chamber (14) in which a larger or smaller portion of the lime is further burnt at a higher temperature, e.g. 1300° C. 
     By means of a splitting gate (16) in the outlet from a separation cyclone (5) for the calciner (4, 14), it is possible to determine the size of the portion of lime which should be exposed to the higher burning temperature in the second calciner chamber (14) and consequently to predetermine the reactivity of the finish-burnt lime.

Abstract: The brewing device (1) for a coffee machine comprises two side plates (2, 3) for fastening the individual parts and for guiding the movable parts. The brewing device (1) comprises a removably attached motor (4) for driving a threaded rod (12). With a nut (13) fastened on the threaded rod (12) and with a bow (14), a brewing chamber (5) is displaced from a coffee-powder filling position into a variable brewing position. Also provided are a brewing piston (6) and a brewing-water supply (7). The arrangement of the motor in the brewing device itself and not in the housing of the coffee machine has the advantage that the brewing device no longer has to be connected to the drive member of a motor, it being possible to avoid an additional source of faults in the assembly of the brewing device. The brewing device can be installed from the sides and from the front. The brewing device forms a variable module for a coffee machine. <IMAGE>

Abstract: Pour la protection d'une broche (2) mue par une broche-mère (6) tournant dans un boîtier (4) est prévu un dispositif de freinage pour l'écrou de broche (6), dans lequel, lors du dépassement d'une force théorique appliquée à la broche (2), deux surfaces de frottement opposées (11, 13) sont pressées l'une contre l'autre. Une surface de frottement (13) est fixée de façon qu'elle puisse tourner à l'écrou de broche (6), et l'autre surface de frottement (11) au boîtier (4) de façon qu'elle puisse également tourner. Selon l'invention, un angle vide (PHI) est prévu pour la fixation garantissant la rotation d'au moins une des surfaces de frottement. Grâce à cette mesure, pour détacher de nouveau l'écrou de broche (6), il ne faut appliquer qu'un couple moins grand que le couple de freinage agissant lors d'une défaillance de la commande.

Adjoining the insertion (14) is a rising slope (12), by means of which the connecting pin (3) is constantly deflected until it reaches the depth of the guide channel (10). Additional shapings on the guide channel (10) increase the reliability against unintentional release of a connection.
