Abstract: The variation of the time (t2) in which current flows from the chock (n1) of the switching power supply to the load (C3, RL), which variation is necessary for the regulation of the output voltage (Ua), is accomplished by means of a threshold switch (S) short-circuiting the coil of the choke.
Patent EP-0292109-B1 (EP)
IPC: B41M5/26
Filed: 1988-04-13
Granted: 1992-05-27
Abstract: A receiver sheet for dye-diffusion thermal transfer printing, comprises a substrate which supports a receiver coat, the receiver coat comprising a dye-receptive material, such as an organic polymer, and a dye-permeable release agent which is a thermoset amino-modified-silicone organic-oligoepoxide resin. The thermoset combination of silicone and organic moeties in the release agent, gives good protection against adhesion between the dyesheet and receiver sheet when they are subjected to short high temperature pulses during printing, while also enabling sharp images of high optical density to be obtained. This balance of properties is best obtained by dispersing the release agent throughout the dye-receptive material, although they can also be applied to the substrate as separate layers.

Abstract: A method and apparatus are specified for testing ferromagnetic materials with magnetic powder, in which the workpiece is introduced into an elongated air coil (1 - 4) with ends bent at right angles. The full magnetic field flows through the workpiece (21). The defects in the workpiece are preferably detected at its top while the magnetic powder (20) is picked up at the bottom and the workpiece is rotated through at least 180 DEG  for observation. The apparatus makes it possible for a workpiece to continuously pass through it, with a continuous observation of the surface of the workpiece being possible at the same time as it is rotated and it being possible to detect transverse and longitudinal defects simultaneously or consecutively. The magnetic flux through the workpiece is produced without touch and without contact. The invention makes possible simple, precise and rapid surface defect testing of ferromagnetic materials without making contact to the workpiece or adjusting the testing apparatus. <IMAGE>

Abstract: The invention pertains to a process and an apparatus for machining axially symmetrical parts on lathes or rotary broaching machines in which the workpiece is held at each end by an axial clamping pin and a clamping jaw assembly, the clamping pins and clamping jaw assemblies cooperating such that the clamping jaw assemblies may be retracted relative the clamping pins when the ends of the workpiece are being machined and may be extended relative the clamping pins when additional support for the workpiece is desired, as, for example, when the central portion of the workpiece is being machined. The clamping pins and clamping jaw assemblies are movable relative each other and relative the workpiece such that machining of both ends of the workpiece may take place simultaneously or sequentially, followed by machining of the central portion of the workpiece, on a single apparatus and as part of a continuous, uninterrupted machining sequence.

Title: Drilling-injection anchor
IPC: E21B10/60
Filed: 1989-07-14
Granted: 1993-03-03
Abstract: The invention relates to a drilling-injection anchor (1) having a thread (3) running on the anchor shaft (2) on the circumferential wall side, a drill bit (5) arranged at the front end, cutters (7) allocated to the drill bit (5) and a central channel running in the axial direction, ending in the area of the drill bit (5) and intended for supplying a drilling fluid. So that the drilling-injection anchor (1) does not soften the bore wall during the drilling operation and can thus be used in both compact and sandy, cohesive soils or in loose rock, the invention proposes that the drill bit (5) has a cylindrical hollow body (10) arranged at a distance from the anchor shaft (2) of the drilling-injection anchor (1) and intended for forming an annular space (28), through which fluid can flow, between the circumferential wall (20) of the anchor shaft (2) and the inner wall (19) of the hollow body (10), the hollow body (10) having a length which corresponds to at least approximately the diameter of the drill bit (5). <IMAGE>

Abstract: The method, usable in particular for low-rate speech transmission, uses vector excitation. A signal frame is represented, on the one hand, by prediction parameters, and on the other hand, by a succession of excitation vectors contained in a dictionary (20) and by amplification gains (Gk) of these vectors, the vectors adopted being determined by searching for the minimum energy of an error signal obtained by subtraction of each vector in its turn, after having submitted to a filtering, from the frame of the speech signal. Before subtraction: each frame of the speech signal is subjected to a short-term analysis filtering and to a weighted synthesis filtering, with coefficients possibly fixed in time, and the amplified vector is subjected to a long-term predictive filtering and to the same perceptual weighted synthesis filtering as the speech signal. <IMAGE>

Abstract: Le procédé pour le séchage de copeaux de bois, avec réduction des émanations, prévoit l'agencement d'un premier sécheur (2) chauffé directement par une chambre de combustion (3). Monté en série avec ce sécheur (2), il est prévu un deuxième sécheur (5), à chauffage indirect, dont l'air évacué est recyclé, par l'intermédiaire d'un conduit (7), vers la chambre de combustion (3). Les gaz perdus provenant du sécheur (2) parviennent dans une autre chambre de combustion (11), dans laquelle ils sont chauffés à au moins 300°C, ce qui permet d'éliminer les substances polluantes. La chaleur mise en jeu à cet effet peut être récupérée au moyen d'une chaudière à récupération thermique (14) et être utilisée pour le chauffage du deuxième sécheur (5).

Abstract: A form, fill, seal and separate packaging machine for reclosable containers is accomplished by a plurality of stations disposed along a path of travel of a thermoplastic web including a pair of mated, resealable closure strips present on the base web. The machine is intermittent in its operation, with movement of the web through the machine controlled so that the various steps of forming, filling, sealing and separating the reclosable containers are performed during periodic stops of the machine. The machine is further characterized by its use of two pairs of web belts to move the web through the machine. A first pair of web belts initially receive the folded web stock and partially form and completely fill the containers. The second pair of web belts overlap with the downstream end of the first pair of belts, but are disposed lower than the first belts. When the filled partially formed containers pass from the first pair of belts to the second pair of belts, the unsealed free ends are exposed for final sealing and severing.

Abstract: Un analyseur de films cinématographiques génère un signal de télévision à haute définition à partir d'une combinaison d'une composante de détail à haute définition et une pluralité de composantes en couleurs à définition moins élevée. La composante de détail est obtenue à partir d'un signal de luminance généré par un capteur à antennes colinéaires (44) possédant une définition des lignes adaptée à l'analyse à haute définition. Les composantes couleurs à définition moins élevée sont obtenues à partir de trois capteurs à antennes colinéaires (36r, 36g, 36b) à basse résolution produisant des signaux rouges, verts et bleus flous. Le réseau de luminance est divisé en segments de taille semblable (44a, 44b, 44c, 44d); plusieurs registres (48a, 48b, 48c, 48d) sont ensuite utilisés afin d'atteindre le débit nécessaire à l'analyse à haute définition. Les photosites en couleurs sont plus grands que les photosites de luminance afin que le rapport signal/bruit soit amélioré. En faisant en sorte que le nombre de photosites dans chaque segment de luminance soit un sous-multiple du nombre de photosites dans le réseau en couleurs, un signal d'horloge commun (42) est utilisé pour extraire tous les réseaux linéaires. De multiples lignes de luminance sont donc sortis pour chaque ligne de couleur, livrant ainsi une définition moins élevée à la fois dans les sens d'analyse vertical et horizontal.
