Abstract: This invention is characterized by providing a plurality of steps for the molten steel flowing hole of the immersion nozzle for continuous casting, in which inner diameters d₁, d₂, and d₃ of said molten steel flowing hole at stepped parts are in such relations that d₁ > d₂ > d, or d₁ > d₂ > d₃ > d, where d is the main inner diameter, and the inner diameter d₂ or d₃ at the part immediately above the molten steel discharge opening is such that (d + 10 mm ≧ d₂ or d₃), and the material of the inner peripheral wall near the molten steel discharge opening is desirably boron-nitride-carbon. Such a composition as above is very effective in preventing deposit and adhesion of Al₂O₃ and is capable of improving the life of nozzle 50% over that of the conventional one.

Abstract: Convertisseur de fréquences pour le transmetteur d'un système de radiocommunications micro-ondes comprenant un mélangeur de suppresion des ondes-image (10) destiné à mélanger un signal FI avec un signal OL ou un signal de fréquence porteuse de façon à produire un signal HF, et un circuit d'annulation destiné à fournir des décalages de courant continu au mélangeur afin de réduire les résidus de porteuse dans le signal HF. Le circuit d'annulation comprend une source (32) de signaux d'interruption périodique en quadrature de phase qui sont transmodulés (34) avec le signal OL de façon à produire un signal modulé, et un mélangeur à sortie unique (38) destiné à mélanger le signal modulé avec une partie du signal HF. Le signal produit par le mélangeur à sortie unique est appliqué à l'entrée d'un filtre passe-bas (40) et le signal filtré résultant est transdémodulé (36) à l'aide des signaux d'interruption périodique de façon à produire des signaux de correction de quadrature phase, qui sont intégrés (44) pour fournir les décalages de courant continu destinés au mélangeur. Le montage évite d'avoir recours à un filtre de fréquence porteuse ultérieur.

Abstract: Pour le traitement d'un programme d'utilisateur sur un système informatique parallèle, les opérations du programme d'utilisateur sont exécutées en parallèle sur différentes calculatrices. Il peut alors se produire qu'une première opération nécessite des données qui sont produites par une deuxième opération. La première opération doit donc attendre, dans le traitement, que la deuxième opération fournisse ces données. Pour ne pas allonger le temps d'exécution du programme dans la traduction de ce programme d'utilisateur, on ouvre, pour les instructions d'une première opération qui font appel à des données produites par une deuxième opération, des cellules de résultat dans une zone de mémoire non adressable en mode utilisateur, cellules où peuvent être inscrites ensuite les données produites par la deuxième opération. Dans le traitement du programme d'utilisateur après la traduction pour le système informatique parallèle, on recherche, pour toutes les instructions comportant un accès à la mémoire, si l'emplacement de mémoire adressé est une cellule de résultat dans la zone de mémoire non adressable. Si tel est le cas, le système d'exploitation interrompt le traitement du programme d'utilisateur et lance, en mode système, un programme d'interruption qui a accès à la cellule de résultat. On détermine alors si le résultat se trouve déjà dans la cellule de résultat et, dans ce cas, ce résultat est fourni à l'opération. Dans le cas contraire, la première opération est interrompue jusqu'à ce que le résultat fourni par l'autre opération soit inscrit dans la cellule de résultat.

Filed: 1992-05-27
Abstract: In the case of magnetic recording by the helical scan method, magnetic heads with symmetric azimuths of the magnetic head gaps are used. However, problems occur if hard-magnetic tape material which is magnetically oriented longitudinally is used, since one of the magnetic heads scans the magnetic tape in a direction in which it is difficult to magnetise. This results in incomplete magnetisation of the magnetic coating of the magnetic tape. The present invention avoids this by using magnetic heads with an asymmetric angular position of the gaps, which are arranged in such a way that in a helical scan recording a symmetric position of the gaps with respect to the easily magnetisable direction of the magnetic tape is obtained. <IMAGE>

Abstract: A slide conveyor (50) for an optical sorting machine is channel-like in cross section, having two sides (62, 64) which converge at an acute angle to form a U-shaped bottom (66). The conveyor is designed to convey generally disc-shaped products having slightly convex sides. The bottom (66) of the conveyor (50) has a radius which is smaller than the radius of the convex sides of the products but which is larger than the smallest edge radius of the products. The conveyor is gently twisted about its longitudinal axis over its length by an angle of approximately 85 degrees. The conveyor slopes at an angle of about 75 degrees to convey products by gravity action. At the upper end (52) of the conveyor (50) a centre line (54) which bisects the bottom (66) stands vertically whilst at a lower end (58) of the conveyor (50) a corresponding centre line (60) is angled at about 5 degrees above horizontal. The conveyor serves both to separate and orient the products conveyed which facilitates inspection in an optical viewing station positioned just below the lower end of the conveyor.

Abstract: 2.1 In chemical oxygen respirators, the oxygen required for breathing is generated from a chemical by the action of the exhaled air. Owing to the reaction course of the chemical, more oxygen is produced than can be consumed in breathing. This has an adverse effect on the lifetime of the respirator. The heat of reaction raises the inhalation temperature. The new chemical oxygen respirator is designed to increase the lifetime and reduce the inhalation temperature. 2.2 Within the breathing bag (2) a further smaller breathing bag is arranged as an exhaling bag (3), specifically to accommodate accumulated exhaled air present at the inlet (1a) of the chemical cartridge (1). The exhaling bag (3) has a pressure relief valve (4) which vents to ambient atmosphere and responds to the pressure of the breathing bag (2). The inhaled air, which is hot owing to the heat of reaction, cools down at the perimeter of the exhaling bag (3) filled with the cooler exhaled air. 2.3 The chemical oxygen respirator according to the invention is a respirator operating independently of the ambient atmosphere and having an extended lifetime. <IMAGE>

Abstract: Todays consumer video A/D and D/A converters or other digital video processing systems are restricted to 8-bit resolution. The quantizing noise introduced in these systems can result in visible artefacts in gradually shaped areas of an image or can lead in applications based on some critical algorithms to very severe distortions. 
It is known to use a dither signal for masking contouring or correlation effects by adding a non-correlated noise signal to the video signal prior to A/D conversion. 
For achieving an increased bit resolution for a given A/D or D/A converter, a special multilevel dither signal in conjunction with multiple oversampling is added to the bandlimited analog input signal which is afterwards converted with a clock rate of n*f s  and to the digital input signal, respectively.

The top (32) of the power pack is exactly symmetrical with the battery compartment cover which it replaces. The power pack has a peripheral wall (36) spaced apart from the sides of the battery compartment mounting the battery contact terminals. Flexible prongs (45, 46) project from the peripheral walls (36) to provide a wiping contact with either a spiral spring negative terminal or a stationary positive terminal.
