Filed: 1985-04-02
Abstract: A ribbon take-up drive mechanism for a universal ribbon cartridge (1) is adapted to engage the ribbon drive shafts of printers of two different designs. The drive shaft positions are different, and the direction of drive shaft rotation is opposite for the two designs. The take-up mechanism is designed such that the ribbon (9) is pinched between the teeth of a direct drive gear (33) and a biased idler gear (41). The printer of one design drives the ribbon through the direct drive gear. The printer of the second design drives the ribbon through an alternative drive gear (63), an idler gear (57) and the biased idler gear. In either case, the ribbon is advanced in the same direction.

Abstract: A method of compression molding powders of metals, ceramics and the like. A thin rubber bag is adhered to the inside of a cavity formed within a permeable mold support so as to define a mold therein and the bag is packed with a raw material powder. The powder in the bag is evacuated to a degree of vacuum to compactiy compress it and the rubber bag is sealed. In this condition, the compressed powder is removed from the support and compression molded to a higher degree of denseness by the CIP process. The inflation adhesion of the rubber bag to the inside of the support cavity is effected by reducing the pressure outside the permeable support.

Abstract: Un système de haut-parleur présente une construction comprenant une enceinte (12) possédant deux éléments d'attaque (14, 16) montés dans la face frontale de l'enceinte (18) et commandés par un réseau électronique de croisement (42). La face frontale de l'enceinte est inclinée vers le haut et vers l'arrière depuis le fond (20) jusqu'à la paroi supérieure (22), d'une manière générale en faisant un angle d'environ 20o par rapport à la verticale. Elle est évidée depuis l'extension antérieure des côtés de la paroi supérieure et du fond, et elle est recouverte, sauf sur les éléments d'attaque, avec un matériau fibreux comprimé absorbant les sons (24). Le matériau est comprimé par un tissu grillagé (32) qui est étiré au moins de part et d'autre de la face frontale du haut-parleur. Le matériau comprimé fibreux absorbant les sons atténue les ondes en surface qui se propagent vers l'extérieur depuis le haut-parleur des graves et le haut-parleur des fréquences élevées parallèlement ou avec un faible angle par rapport à la face frontale de l'enceinte, et les éventuelles réflexions provenant des coins de l'enceinte sont même encore plus atténuées. Grâce à la face frontale inclinée, le réseau de croisement peut être conçu en ayant des différences de temporisation de groupe constantes sur la première ou les deux premières octaves de chaque côté de la fréquence de croisement, de sorte que l'on obtient une meilleure réponse de phase et une interaction minimum entre les éléments d'attaque.

Abstract: For first and second polarization controlling elements (181, 182) driven by first and second driving voltages in a polarization controlling device, a beam splitter (15) has a dividing ratio controllable between 1 : 0 and 0 : 1 and divides an input polarized beam laving an input polarization state. An output polarized beam is derived from first and second polarization controlled beams to have an output polarization state. While the dividing ratio is kept at 1 : so that the second polarization controlled beam is null, the first driving voltage may approach either of a positive and a negative limit. In this event, a control unit (25) changes the dividing ratio to 0 : 1. Even while the second polarization controlled beam is null, the control unit controls the second driving voltage so that the both driving voltages are congruent modulo a unit voltage difference which makes each element carry out equivalent polarization control. The first driving voltage is likewise controlled.

Abstract: A reactive layer of, for example, CuO or titanium of a layer thickness of at least 100 nm and, on top thereof and in the same working step, a second layer of copper, silver, gold or nickel having a layer thickness of at least 100 nm are vapour-deposited at a pressure from 10<-><8> to 10<-><4> mbar, and the second layer is reinforced chemically or electrochemically until a layer thickness of 0.004 to 0.020 mm is reached, and the actual bonding step is then carried out in an oven with a blanketing gas atmosphere. For this, a temperature is selected which is between the eutectic temperature of the material of the first layer and the metal of the second layer on the one hand and the melting point of the metal of the second layer on the other hand, whereupon the material is gently cooled after a holding time of approximately 1 minute. In this way, a completely bubble-free, brazeable layer can be obtained which adheres very well to substrate surfaces of different roughnesses.

Abstract: A method for melting a metal in an induction plasma furnace consists in melting the metal (2) by means of the plasma arc (8) and the magnetic field of the inductor (4) and in effecting an interaction between the plasma arc (8) and the magnetic field of the inductor (4), this interaction being accompanied by fluctuations in the energy parameters of the plasma arc (8) and by the appearance of an acoustic pressure. Then, the values of the energy parameters of the plasma arc (8) are analised and compared with the preset values of the energy parameters of the plasma arc (8). At the same time, the acoustic pressure level is measured at each moment of its appearance during the interaction of the plasma arc (8) with the magnetic field of the inductor (4) while the plasma arc (8) is penetrating into the melted metal (2), and the intensity of the magnetic field of the inductor (4) is reduced until the acoustic pressure is eliminated.
