Abstract: PRECIS DE LA DIVULGATION:      Machine et procédé pour l'élaboration d'un produit la-miné, à partir d'une ébauche obtenue par coulée continue d'un métal ou alliage liquide dans une roue refroidie munie d'une gorge périphérique fermée sur une partie de sa circonférence par un ruban métallique formant une boucle sans fin, entraîné à la vitesse circonférentielle de la roue qu'il enveloppe par-tiellement, le métal ou l'alliage liquide étant déversé en per-manence en un point fixe constituant l'extrémité amont fixe de la partie fermée de la gorge, dans laquelle il se solidifie au moins partiellement pour ressortir en aval sous forme d'une é-bauche continue qui est elle-même ensuite introduite dans un laminoir continu. Selon ce procédé, quelle que soit la nature du produit travaillé, on se place toujours dans les conditions optimales du couple vitesse-température de la vitesse de la roue et température de l'ébouche assurant à la fois de bonne condi-tions de coulée et de bonnes conditions de laminage ultérieur. Pour ce faire, on agit indépendamment d'une part sur la vitesse de la roue, d'autre part sur la longueur de produit emprisonné dans la gorge de la roue par modification de la longueur de ru-ban appliqué sur la roue, en faisant varier le point aval de séparation roue-ruban où l'ébauche sort de la gorge.

Abstract: ABSTRACT OF THE DISCLOSURE:         A motor-driven rail-vehicle with a drive system includ-ing an electric motor and drive wheels is provided with an oscil-lation sensing member which senses oscillations within a pre-determined frequency range of an electrical quantity of the drive system, such as the armature current or voltage, and forms a signal representing such oscillations.  This signal is compared with a signal corresponding to a predetermined threshold value, and the tractive force of the motor is reduced in response to an increase of the oscillation amplitude above such threshold value.

Abstract: ABSTRACT In a method and a device for treating waste water it is known to use active carbon.  In known devices problems arise with the removal of spent, active carbon.  The present invention seeks to provide an apparatus and a method for treating waste water in which the water to be treated is introduced at the top of a column of active carbon and flows down through it while spent active carbon is removed from the top of the column in a slurry while introduc-ing an equivalent amount of fresh or regenerated active carbon in a slurry form at the bottom of the column.  The present invention provides a method and apparatus in which waste water may be treated with active carbon which is continually replaced at the same rate it is consumed, with a minimum of delay on the treatment operation.

Abstract: ROBERT N. LEVINN     FAIL SAFE CIRCUIT FOR HEAT GENERATING  DEVICE     ABSTRACT OF THE DISCLOSURE           A heat generating device, such  s an oven, includes a heating element connected to a power source and a fuse interposed therebetween.  The fuse is effective, when the magnitude of the current flowing thereto exceeds the fuse rating, to disconnect the element from the source.  A thermostat is included in the circuit to control the current flow and, thus, the temperature level.  In the event of a malfunction of the thermostat, tem-perature responsive means are effective, when the temperature sensed thereby exceeds a given level, to increase the current flowing through the fuse beyond the fuse rating.  The temperature responsive means includes a temperature sensitive switch and a resistive element which may be a second heating element.  When the switch is closed by excessive temperature, the resistive element is placed in parallel with the heating element, thus lowering the effective resistance of the circuit to increase the current.
