Patent EP-0491172-A1 (EP)
Inventor: WOSEGIEN BREND
IPC: B60T15/02
Filed: 1991-11-18
Abstract: The emergency brake device for railway vehicles has a piston-operated air relief valve (4) for the main air line, which valve can be controlled by means of a manually operable emergency brake valve (33). In order to be able to suppress emergency braking on sections of track unsuited to this, the air relief valve (4) can be loaded in the closing direction by a locking plunger (18) loaded by a spring (20) and a second locking plunger (24) is capable of locking the first-mentioned locking plunger (18) in its position corresponding to a closed air relief valve (4). This locking of the air relief valve (4) can be controlled by reducing the pressure in the main air line below a residual pressure level attainable in emergency brake operation and can be cancelled again only by introducing a pressure level exceeding the control pressure level in the main air line. When the air relief valve (4) is locked in the closed position, the brakes can be released and the railway vehicle can continue to travel until a section of track suitable for stopping is reached. <IMAGE>

Abstract: An acceleration sensor comprises a tube (14) formed of an electrically-conductive, nonmagnetic material; an annular magnetically-permeable element (18), such as a iron washer, encircling a longitudinal portion of the tube (14); a magnetic sensing mass (32) in the tube which magnetically interacts with the washer (18) so as to be magnetically biased towards a first or "rest" position in the tube (14) characterized in that a longitudinal portion of the sensing mass (32) is situated within the portion of the tube (14) encircled by the washer (18), the sensing mass (32) being displaced from its rest position in the tube (14) towards a second position therein in response to an accelerating force exceeding the magnetic bias thereon; and a switch (28) operated by the sensing mass (32) when the sensing mass is displaced to its second position in the tube (14). The instant accelerometer features a low threshold magnetic bias of the sensing mass to provide a quickened sensing mass response to acceleration inputs of short duration; and a magnetic bias which increases in a substantially linear manner with increasing sensing mass displacement from its rest position towards its second position within the tube (14).

Abstract: The present invention relates to an electronic device for automatic communication between automobiles, automatically sending signals making it possible, in particular, to warn the driver of a potential danger, and to avoid collisions. The method of information transmission between mobile units, such as automobile vehicles, consists in equipping each vehicle with a separate information transmitter and receiver, communicating by radio waves, the transmitter of a first vehicle broadcasting to the receivers of other vehicles situated in its vicinity coded information relating to actions of the said first vehicle, each receiver comprising means for transcoding the said coded information intended for the driver of the corresponding vehicle. The information is transmitted in the form of a frequency-modulated carrier wave at a modulation frequency which is a function of a specific frequency FM of the information item to be transmitted. According to the invention, an information item is more precisely transmitted at hyperfrequency in the form of two pulses, one to the front of the vehicle with a modulation frequency FMAV, the other towards the rear of the vehicle with a modulation frequency FMAR, the two frequencies FMAV and FMAR being different and functions of the specific modulation frequency FM. This transmission method makes it possible for receivers in the vicinity to distinguish an item of information originating from a mobile unit going in the same direction as them, from an information item originating from a mobile unit coming in the opposite direction.   <IMAGE>

In an alternate embodiment, a chlorite solution is introduced into the reaction chamber together with the chlorate solution and the gaseous stream of acid. In a further embodiment, a chlorite solution is introduced into the reaction column after mixing of the driving medium with the chlorine dioxide.

Abstract: Tige d'outil (10) destinée à retenir un outil ou un capteur de contact dans l'embout femelle (S) de la broche d'une machine-outil, comprenant 6 zones de surface qui, en fonctionnement, appuient contre la paroi de l'embout femelle (S). Les zones de surface sont équipées de trois billes (34, 34'), une des ces trois billes étant soutenue de manière à faire ressort pour permettre le mouvement radial par rapport à un axe de la tige (A) sur une petite partie de rebord (26) (Fig. 2) située à une extrémité de la tige (10), trois autres billes (36) étant encastrées dans l'autre extrémité de la tige (10). Lorsque la tige est entraînée dans l'embout femelle (S) la petite partie de rebord (26) se déforme, permettant à la bille (34') de se déplacer radialement à l'intérieur jusqu'à ce que la surface des boucles (36) viennent au contact de la paroi de l'embout femelle (S). Un boulon à épaulement décalé vers l'amont (38), soutenu sur un bloc en forme de cône tronqué (40) est connecté à la tige par un piston (42) et par un ressort à pression (46). Le mouvement de rétraction de la tige dans l'embout femelle, lorsque le boulon à épaulement (38) fait ressort contre les petites parties de rebord (26) entraîne le piston (42) à comprimer le ressort (46) jusqu'à ce que le bloc (40) appuie fermement contre la paroi de l'embout femelle (S). Ce dispositif évite de faire porter des charges excessives sur la tige et sert à la retenir dans l'embout femelle (S).

Abstract: Lors de l'utilisation d'un moteur à haute vitesse pour l'entraînement d'une broche d'une machine outil, il y a un risque de diminution de la précision de l'usinage qui peut être dû à un déséquilibre même léger des pièces en rotation. Pour éliminer ce risque on utilise des éléments annulaires de formation de labyrinthes (22F, 22R) au niveau des parties antérieures et postérieures du moteur, ainsi qu'un élément d'engrenage de détection de révolutions (24G) d'un arbre de sortie (14), qui font partie du moteur. Autrement dit, on perce plusieurs trous taraudés (22A) sur la surface extérieure de chacun de ces éléments et on effectue un réglage de l'équilibre par engagement d'un composant fileté (26) dans le trou taraudé à une position appropriée, tout en mesurant une quantité de déséquilibre après l'assemblage du moteur.

Title: Process for producing the electric insulation of electric machine windings.
Inventor: SCHORM JOSEF
IPC: H02K15/12
Filed: 1991-07-03
Abstract: In order to produce the electric insulation of the winding of an electric machine, grooves (6) having a cross-section that tapers at least in an area (12) near to the groove opening (11) are arranged in the rotor or motor. Before the winding is laid in the grooves (6), the latter are lined with a laminate (5) that contains an elastically compressed mass of high-elastic, electrically insulating fibres and a solidified, curable synthetic resin that can still be thermally softened, however, and that holds the mass of fibres in its compressed state. Once the winding is laid and the grooves are closed (6), the rotor or stator is subjected to a vaccum pressure impregnation, then cured. During the impregnation process, the hot saturating resin penetrates into the pores of the elastically expandable laminate, elastically expanding the mass of fibres and filling the empty spaces in the grooves, so that the elastically expanded mass of fibres, that is supported at the surface of the groove, exerts on the upper subconductor bundle (8) of the winding a force in the direction of the bottom (10) of the grooves.

Filed: 1991-08-15
Abstract: A device for releasably locking, in a tubular first member (1), a second member (2) which is displaceable in the first member, has a slide (6) mounted on the first member. A driver pin (7) on the second member <2) extends through a slot (4) in the first member and through a hole in the slide to entrain the slide in the displacement of the second member. A spring (9) urges an operazing lever (8) rotatably mounted on the driver pin (7), towards the slide (6). The slide has cam means (10) cooperating in such a manner with the operating lever (8) that this lever, when being rotated from a free position to a locking position, is urged out from the slide against the action of the spring (9), such that the spring urges the driver pin (7) outwardly so as to resiliently urge the second member (2) against the first member (1) which is thus clamped between the slide (6) and the second member (2), whereby to lock the latter in its position of displacement.
