Abstract: In an apparatus for searching desired track by transferring and controlling the reproduction position of the pickup for reproducing the signal recorded on a recording carrier (1) on the basis of reference transfer information, the traveling load is measured, and the value of the reference transfer information is corrected according to this measured value, so that the desired track may be searched stably. The transfer motor (13) is driven so that the reproduction position may move at a constant velocity, and the traveling load is measured (36). The transfer motor is driven so that the moving speed of the reproduction position or the time for moving a specified distance may be predetermined specific value, and by this driving signal, the value corresponding to the traveling load is determined.

Abstract: Disclosed is a device for manufacturing fused-elongated type optical fiber couplers having a chassis, a pair of movable stands provided within the chassis forming a space therebetween, optical fiber mounting units for mounting and fixing two or more component optical fibers on the above mentioned pair of movable stands, and a drive mechanism whereby the pair of movable stands can be driven back and forth in a direction parallel to the longitudinal axes of the component optical fibers. By virtue of the space formed between the two movable stands, a heat source can be applied to the aligned portions of the component optical fibers, thereby effecting thermal fusing of the aligned portions, after which drawing out of the thus fused section can be effected using the above mentioned drive mechanism for the movable stands, and additionally, a protective case for surrounding and reinforcing the manufactured optical fiber coupler can easily be applied without removing the optical fiber coupler from the apparatus through the above described space.

Abstract: The present specification discloses a wheel incorporating a brake disc (7). The wheel comprises a central hub (1) and an outer rim (3) interconnected by a web (5), with a pair of annular braking discs (7) being mounted one on each side of the web (5) by means of at least two connection assemblies (9). 
     To avoid the problem of thermal stress cracking which occurs after a period of use when braking discs (7) are bolted directly to the web (5), the connection assemblies (9) each comprise a plate member (11) which is slidably retained in a generally radially extending slot (15) in the rear face of a braking disc (7). The plate members (11) are preferably flexible and of a thickness which is less than the depth of the slot (15). Attachment means (25,27) secure the plate member (11) to the web (5) so that the braking discs (7) are solely subjected to the pull of the flexed plate members (11) irrespective of how tightly the attachment means (25,27) secure the plate member (11) to the web (5).

Abstract: The reservations of occupations of the horizontal (Hi) and vertical (Vj) links of the connection matrix (S/T) having to be selected in order to permit the transfer of incoming cells, each one to at least one outgoing artery (Sj), are recorded in an occupation table (TAB-OCC ET PRIO), for each one of a given number of transfer periods. For each new incoming cell, a transfer period is selected during which the horizontal link and the or each vertical link, selection of which is required to ensure the transfer of this new incoming cell, are free in the occupation table, the occupation of these links is marked in the occupation table for the selected transfer period, and the time shift with which it will be possible to effect the transfer of the new incoming cell is determined. With each new transfer period, the occupation table is shifted, the horizontal and vertical links for which occupation was recorded in respect of this new period are selected, and the cells whose transfer is to be carried out during this period are read from the memories of the input circuits, the reading of a cell being delayed, relative to its recording, by a quantity corresponding to the time shift determined in respect of this cell. <IMAGE>

Abstract: The apparatus comprises a thermal postcombustion device (37) and a steam boiler (1). In the device (37) pollutant-laden exhaust air from a source (30), for example a tenter, is heated to approximately 750 DEG  Celsius, so that all organic pollutants in the exhaust air are burnt. The purified gas is cooled over a gas-water, ribbed pipe heat exchanger (50). The heat exchanger (50) is fed by a pump (55) on the water side with water (9) from the boiler (1). The water-side outlet (56) of the heat exchanger (50) is connected to the boiler (1) by way of a pressure reducing valve (61) and a separating device (75). The valve (61) is so adjusted that the water pressure in the heat exchanger (50) is greater than the steam pressure. By means of this apparatus steam can be generated using the waste heat from the device (37) cost effectively and with a low space requirement. <IMAGE>

Inventor: SCHEMEL JOHN H
IPC: C22F1/00
Filed: 1990-10-17
Abstract: A continuous solution heat treating process for precipitation hardenable alloys. The alloys can be in the form of tubing, strip, or other long products and are heat treated by a continuous process by passing the product along a feed path continuously through a heating zone in a vacuum or inert gas atmosphere followed by rapid cooling through an inert gas quench or water quench at a rate to prevent precipitation of secondary phases in the alloy. The inert gas quench can be performed in combination with passing the product in close proximity to or contact with a cooled surface, such as a water-cooled copper cooling device. The process results in very little surface oxide which can be easily removed. The final product can be re­solution treated prior to aging or aged after final cold working of the product.

Abstract: Dans la structure du rotor d'un moteur sychrone du type radial ayant un arbre (12) composé d'un matériau magnétique dans lequelles éléments du noyau l'induit (20) sont maintenus par des aimants (18), l'arbre magnétique (12) provoque une fuite de flux pendant sa magnétisation ou la rotation du rotor, diminuant ainsi la magnétisation et la puissance de sortie. La fuite de flux magnétique est diminuée en réduisant le diamètre d'une partie de l'arbre (12a) tournée vers la surface interne du corps du rotor (10). Cette diminution de la résistance de l'arbre (12) à se plier est compensée en bouchant l'espace entre le corps du rotor (10) et une partie de l'arbre (12a) avec un matériau de résine (22) et en formant un noeud.
