Abstract: This invention relates to a muffle furnace, for continuous heat treatment during passage of material therethrough, of products, the production cycle of which includes a treatment of predetermined duration at a temperature which may be about 1100 DEG  to about 1150 DEG  C., which furnace is heated by a flame producing burner without the combustion gases directly contacting the products to be treated. This furnace comprises: an inlet zone provided with a means for preheating, by circulating recycled combustion gases in a double casing provided around the muffle; a heating zone, provided inside a heat-insulated chamber provided with at least one means for circulating combustion gases around the heating zone of the muffle; and an outlet zone provided with at least one means for controlling the cooling rate of the treated product. For the heat treatment of refractory or carbon-containing products, impregnated with a carbon-containing material such as pitch, the pyrolysis of which produces combustible vapors, the heating zone is divided into three sections by means of an additional partition: a zone for exuding and removing volatile materials from the pitch; a zone for pyrolyzing and carbonizing the pitch; and a final firing zone.

Abstract: The device is intended for the distribution of a large number of components, such as, for example, electrical components for the carrying out of process involving the assembly of electrical circuits on mounting plates. The device is made up of a number of elongated magazine boxes (2), each with several receiving hollows (2). By means of two powered endless chains (3) arranged in each case on the side of the magazine boxes (2) after the fashion of a dumbwaiter conveyer with a turn-around chain sprocket (4), the boxes are moved to the vicinity of a receiving window (6). In addition, the device is fitted with a restraint mechanism which holds the individual magazine boxes (2) and their receiving hollows (5) in a horizontal position while they are moving along the endless chain (3) path. In cases where a large number of magazine boxes with their receiving hollows are expected, the invention offers the possibility of reaching within a relatively short time any desired magazine box situated along the endless chain. To this end the two endless chains (3) are fitted at regular intervals with rods (12) projecting towards the center on which the holding elements (13) which serve to hold the magazine boxes (2) are mounted so as to rotate. These holding elements (13) are fitted with dwelling elements (16) which can be locked at prescribed angle positions in relation to the endless chain (3).

Abstract: Un rhéomètre permettant d'étudier les propriétés élastiques d'un matériau présente deux arbres coaxiaux (23, 29) dont les extrémités mutuellement adjacentes sont pourvues chacune d'une sonde de mesure (25, 32) conçue pour s'engager dans un échantillon (P) du matériau. Un arbre est rotatif tandis que l'autre est fixe, et au moins sur ce dernier sont fixés des rubans magnéto-élastiques dont la perméabilité magnétique varie lors de la transmission audit arbre fixe, par l'intermédiaire de l'échantillon situé entre les sondes de mesure (25, 32), d'une force rotative provenant dudit arbre rotatif. La variation de la perméabilité magnétique peut être lue au moyen de bobines primaire et secondaire entourant sans contact ledit arbre et reliées respectivement à une source de tension et à un appareil de mesure. Pour entraîner l'arbre rotatif, on fait appel à un moteur électrique (21), mais on peut également remplacer l'arbre entier par un ruban ou une tige magnéto-élastiques entourés par une bobine pouvant être reliée à une source de tension et de courant. Cet agencement s'utilise également avec un arbre fixe pour en contrôler le couple.
