Patent EP-0202417-A1 (EP)
Inventor: BECKER ERWIN PROF DR
IPC: B23P15/16
Filed: 1986-03-18
Abstract: A method for producing spinning nozzle plates having spinning nozzle channels employs a mold plate which contains mold channels corresponding to the spinning nozzle channels. The mold plate is initially connected with a galvanic electrode containing feed channels which communicate with the mold channels. Then negatives of the spinning nozzle channels are produced by filling the mold channels and the feed channels with an electrically insulating molding material and thereafter removing the mold plate, so that columns of molding material remain connected to the galvanic electrode. Finally, a galvanic layer enclosing the negatives of the spinning nozzle channels is produced, the galvanic layer is leveled, and the negatives as well as the remaining mold material are removed. The mold plate itself may be produced by depositing a layer of resist material on a further galvanic electrode, irradiating the resist layer in a predetermined pattern using high energy radiation, selectively removing portions of the irradiated resist layer to produce negatives that are connected to the further galvanic electrode, depositing a further galvanic layer, and removing the negatives. These techniques permit economical production of spinning nozzle plates, particularly plates having nozzle capillaries with specially shaped cross sections and small critical dimensions.

Abstract: Un rouleau de formage pour laminoirs de tuyaux sert à former des tuyaux, tels que des tuyaux à soudure continue, par formage continu. Un procédé et un appareil permettent de former des bandes de matériau avec ce rouleau de formage. Le rouleau de formage présente une courbe développante fondée sur un polygone composé d'une pluralité de côtés prédéterminés de sorte que la section transversale de la surface du rouleau ait la forme de surfaces courbes dont les rayons de courbure varient constamment selon un rapport mutuel constant. Les surfaces courbes à rayons de courbure divers peuvent être déterminées sur la surface du rouleau selon le diamètre des tuyaux que l'on veut produire. Ainsi, dans un appareil utilisé pour former la partie terminale de la bande de matériau, par exemple, on peut changer la distance entre deux rouleaux de formage selon la largeur de la bande de matériau. De même, on peut ajuster l'orientation des rouleaux de sorte qu'ils butent de manière correcte contre la bande de matériau. La partie terminale de la bande de matériau peut ainsi recevoir la forme voulue, car les rouleaux de formage auront la partie courbe superficielle requise pour former des tuyaux ayant le diamètre voulu. Lorsque ces rouleaux sont utilisés comme rouleaux horizontaux, rouleaux latéraux ou similaires à chaque étape de l'opération de formage, on peut réduire le nombre d'étapes à rouleaux de formage. On peut en outre effectuer des opérations de formage pour produire des tuyaux en acier à diamètres divers, depuis les plus petits jusqu'aux plus grands, et à parois d'épaisseurs diverses, sans avoir à remplacer les rouleaux de formage.

Abstract: An amplifier arrangement for reducing an unwanted d.c. offset of an amplitude-varying input signal, comprising a threshold circuit (A3, B 3 ) and an amplifier stage (A 1 , B 1 ) coupled thereto, which threshold circuit (A3, B 3 ) is provided with a bistable trigger circuit (A 4 , B 4 ). This bistable trigger circuit (A 4 , B 4 ) reduces the d.c. level of the input signal or output signal of the amplifier stage (A 1 , B 1 ) in a steplike manner when this d.c. level increases. The bistable trigger circuit (A 4 , B 4 ) has a hysteresis which is larger than the maximum amplitude variation of the input signal as a result of the desired signal component, so that a linear amplification of this desired signal component is possible and, in the case of a non-varying d.c. level, variations of the input signal due to the desired signal component cannot give rise to a d.c. reduction. This amplifier arrangement may be used in a phase-locked loop of a directly mixing synchronous AM receiver, which phase-locked loop is used for generating a synchronous local carrier in order to increase the input dynamic range of the receiver.

Abstract: Methods and apparatus are provided for overcladding a preform rod (22). The preform rod is aligned with and inserted into an overcladding tube (30). The outer diameter of the preform rod and the inner diameter of the tube are such that the clearance between the tube and the rod does not exceed a predetermined value. Successive increments of length of the tube and rod therein are subjected to a controlled zone of heat while the pressure inside the tube is maintained at a value which is substantially less than that outside the tube. This causes the tube to be collapsed onto the preform rod to provide an overclad preform and subsequently is substantially concentric with respect to the optical fiber core.
