Patent EP-0232940-A1 (EP)
Inventor: DE HAAN GERARD
IPC: G11B15/14
Filed: 1987-01-30
Abstract: When, for example, MAC signals ( inter   alia  C-MAC or D2-MAC signals) are recorded directly on a video recor­der and no special steps are taken, information will be lost as a result of the change-over from recording by means of one write head (7) to recording by means of an­other write head (8). The relevant signals to be recorded comprise a sequence of lines with a first signal block (F i ) containing a line-synchronising signal and at least one additional signal, and a second signal block (S i ) con­taining the chrominance and luminance information of the video signal. In accordance with the inventive step specific first signal blocks (F₁, F i , F j , F k ) or at least the additional signals of these first signal blocks are accommo­dated in a second signal block (S n ) of a non-relevant video line and are subsequently recorded on the record carrier. After the relevant second signal block (S n ) has been read from the record carrier the relevant first signal blocks, or at least the additional signals of these first signal blocks, are extracted from the second signal block and re-inserted into the data stream of first signal blocks at their original locations. The relevant first signal blocks may be those first signal blocks during which the heads are switched (Fig. 1a and 1b) or may be other (subsequent, when viewed in the time) first signal blocks (F n-3  to F n ) which can no longer be inserted into the data stream of the first signal blocks because these first signal blocks, during which head switching is effected, have been repeated earlier in the data stream (Figs. 7a and 7b).

Abstract: A device is disclosed which produces high current, low noise, low lateral energy, stochastic electron emission from a multiplicity of insulative particles subjected to a field. The insulative particles are in and of a surface thickness comprised of a random mixture of insulative and conductive particles in ohmic contact. Emission is achieved at applied potentials of about 5 volts which produce a field sufficient to emit electron currents of nanoamperes to milliamperes. Single devices or arrays of devices may be batch fabricated. each device has an integral, implicitly self-aligned electron optic system comprising means for modulating, focusing and deflecting the formed current beam, and means shielding the device from ambient magnetic fields.

Abstract: A status-indicating fuse of the electrical system of automobiles, machinery and generally any mechanical device, has parallel with the fine melting wire (4) of fuses an indicator lamp (3), which operates with very low current intensities and which has a large electrical resistance. The entire system of the indicator lamp and the melting wire of the fuse are contained within the protective glass cover of the fuse (2). When the electrical system is functioning normally, current flows through the fuse through the fine melting wire, because this presents a very small resistance in comparison to the parallely connected indicator lamp. At this stage, the in­dicator lamp does not light. However, for whatever reason a high current passes through the fine wire, this wire melts and the indicator lamp, which is now connected serially to the cir­cuit, illuminates, thus showing the burnt fuse.

Abstract: Dans une machine de fabrication de sacs pour la formation de lignes de perforation et de soudage dans une bande allongée (7) un agencement comprend un pincement constitué d'un cylindre de pincement (4) et un cylindre d'appui (5). Au moyen de ces cylindres la bande (7) passe dans la machine (1). Une lame de coupe allongée (10) est parallèle aux cylindres (4, 5) et peut tourner autour de son axe longitudinal. Lorsqu'elle est en rotation, elle est amenée à s'engager avec le cylindre d'appui (5) pour former les lignes de perforation. Deux unités de soudage (8) avec leurs mâchoires d'étanchéité (22) permettent de former les lignes de soudure. De manière à permettre le réglage de l'espacement entre des lignes de perforation consécutives et des lignes de soudure, la lame de coupe (10) peut être connectée et déconnectée indépendamment du fonctionnement des cylindres de pincement (4, 5) ou de tout autre moyen d'entraînement de la machine (1). La lame de coupe (10) et des unités de soudage (8) sont entraînées par des couplages à effet rapide pour la rotation pas-à-pas de la lame de coupe (10) suivant des angles prédéterminés et le déplacement pas-à-pas des mâchoires d'étanchéité (22). Un capteur d'angle mesurant la longueur de la bande passant dans la machine (1) commande la rotation de la lame de coupe (10).

Abstract: This system employs writing of lithographic patterns with a shaped electron beam exposure system (10) which minimizes the time wasted by workpiece positional requirements. The writing field contains an array of sub-fields written in a raster sequence. The large width of the writing field (37) provided by the VAIL system reduces the number of mechanical scans required to write the pattern on the workpiece which further reduces the time required for workpiece positioning. When patterns are being superimposed over previously written patterns, registration is employed. This system includes a registration field (36) confined to local areas on the workpiece (7), which is larger than the writing field, without requiring change in focus and without requiring the mechanical system comprising the X-Y work table to change speed during the registration and reregistration of the various fields on a semiconductor wafer or mask. The registration field can be larger than the writing field, because the quality requirements demanded from the shaped electron beam(B) are less for detecting the locations of such registration (39) marks at the various locations on the wafer.

Abstract: Process and device for short-circuit arc welding in which a continuously fed welding wire alternately passes into an arc phase and a short-circuit phase, the wire being at a distance from the molten pool of the workpiece during the arc phase, and the molten metal at the end of the welding wire touching the pool of molten metal during the short-circuit phase and then passing to the workpiece by pinch effect, which tears the molten metal from the wire. The improvement consists in the fact that a first current-control circuit (22) with high inductance is provided which continuously conducts a background current of low intensity between the welding wire and the workpiece, which background current supports the arc, and that a second current-control circuit (24) is provided which controls the current flow during the arc phase of the melting process. This second current-control circuit (24) has time-delay means which allow the arc at the start of the arc phase to occupy an area which is primarily determined by the background current for a preselected time during which the molten metal on the tip of the welding wire and in the molten metal pool is drawn by surface tension against the wire and/or into the welding pool, the latter essentially being pressed down, and means being provided which then allow a high current surge to run with preselected energy through the arc between the wire and the welding pool in order to melt a relatively constant volume of metal at the end of the wire and at a distance from the molten pool. This high energy pulse takes place near the start of the arc phase and generally ends before the centre of the arc phase so that the wire is first melted and then directed into the molten metal pool after the pool has essentially been pressed down or has steadied. <IMAGE>

Abstract: The invention relates to a safety device for a self-propelled earthmoving appliance having a hydraulic transmission with a reverser and at least one stabilizer which can serve as a support for the said appliance. 
     According to the invention, the safety device comprises control means (23, 24, 25, 26) connecting the stabilizer control lever functionally to the valve means (60) controlling the position of the reverser, the said control means being passive when the reverser is in the neutral position and active when the reverser is not in the neutral position, in order, in the latter case, to cause a return to the neutral position automatically. Con­sequently, the raising of the stabilizer or stabilizers can under no circumstances cause a movement of the machine if the control lever of the reverser is not in the neutral position. 
     The invention is used for equipping appliances of the shovel-loader type having a pair of stabilizers mounted at the rear of the chassis.
