Abstract: Circuit à diode, dans lequel le bruit de scintillation que produit la diode est réduit, comprenant une diode (D1) reliée en séries à une résistance (R2) et un condensateur en dérivation (C1) qui est parallèle à la résistance. Dans l'un des modes de réalisation, le côté de la diode qui est éloigné de ladite résistance (R2) est connecté à une entrée d'un amplificateur de différentiel en courant continu à anode négative (A1) par le biais d'un filtre passe-bas (L1, C2). La sortie de l'amplificateur est renvoyée de manière négative à la jonction de la diode (D1) et de la résistance (R2) de sorte que cette dernière fait office de charge d'amplificateur. On applique à l'autre sortie de l'amplificateur une tension de commande d'une intensité telle qu'on obtient la polarisation voulue de la diode. On peut varier ce modèle fondamental de circuit de diodes de manière à l'adapter pour diverses autres fonctions, telles que la limitation de l'amplitude, la commande de fréquence et la modulation.

Abstract: The geared pump has two externally intermeshing gears (12, 13), the shafts (14, 15) of which are supported in bearing elements (16, 17). These parts can be axially displaced to a slight extent in a housing (10), which is tightly sealed at both sides by covers (18, 19). Between one of the bearing elements (16) and the adjacent gear side faces is a sealing plate (23), which is pressed onto the gear side faces by pressure springs (25, 26). In this way pressure medium from the high pressure side is prevented from accidentally flowing to the low pressure side. One of the pressure springs (25), however, can be relieved so that the sealing plate lifts off from the gear side faces so that a certain proportion of the pressure medium can flow from the high pressure to the low pressure side for the purpose of regulating the feed quantity. In this way the feed quantity is reduced. These drainage paths are so designed that no overheating can occur due to the pressure medium draining off on the sealing plate as a result of frictional forces. <IMAGE>

Abstract: A tape cassette particularly for a 8 mm videotape cassette recorder has a double-lid structure formed by a front-lid (23) and a back-lid (32). A guide (37) is formed on the inside of the cassette housing (10) to define rotation of the back-lid (32). The shape of an upper portion of the guide (37) is determined as an arc of which the curvature radius (R) from a rotation centre of the front-lid (23) is selected in a range of from 5 to 6 mm. When the back-lid (32) is closed in a ganged relation with the front-lid (23), a clearance (L) of greater than 1.5 mm is maintained between the bottom edge portion (40) of the back-lid (32) and an upper edge of the magnetic tape (15). Since no contact between the back-lid (32) and the tape (15) can occur, damage to the magnetic tape (15) can be prevented.

Abstract: Apparatus and methodology for rounding the bristle tips of twisted wire brushes (26). Each twisted wire brush (26) is mounted in a carrier (28) by means of a spindle (30) which permits the brush (26) to be rotated along its longitudinal axis. The melting of the synthetic bristle tips takes place in a heated chamber (20) which includes one or more heated cylindrical cavities (38) which may extend over a portion or the whole of the length of each brush (26). When the carrier (28) approaches the chamber, the chamber (20) is lowered over the carrier (28) so that each of the individual brushes (26) is inserted into a heated cavity (38). When inserted in the cavity (38) the brush (26) is rotated on the spindle (30) while it is heated. The rotation and heating causes the individual bristle tips to melt into a rounded ball without adhering to each other. 
Thereafter, the heating chamber (20) is raised, the carrier (28) indexed and the process repeated.

Abstract: A method for avoiding latent errors in a logic network for majority selection of binary signals in a triplicated system. Errors which result from errors or faults in one of two or more parallel-connected transistors of one or more separate logic devices included in the logic network are avoided by repeatedly switching each of the separate logic devices in a manner such that transistors which were parallel-connected become series-con­nected, and vice versa. As a result, these devices will perform alternatively logic operations which are the dual correspondence of one another, e.g. NAND- and NOR-operations with the aid of the same transistors (61-66) in both instances. Thus, in practice, majority selection will be performed alternatively with two mutually different logic networks, which are the dual correspondence of each other.
