Title: Dispositif de centrage et procédé de fabrication d'un connecteur pour fibre optique
Inventor: MALSOT CHRISTIAN
IPC: G02B6/36
Filed: 1979-09-06
Abstract: L'invention concerne le raccordement des fibres optiques, en connecteurs unitaires ou multiples. Le raccordement des fibres optiques doit impérativement se faire avec une grande précision de centrage de la fibre (1, 1') dans un embout (10, 10'), dans le but d'avoir une bonne transmission lumineuse à travers la connexion. L'invention prévoit: d'une part d'utiliser l'embout comme moule pour l'injection de polymère ou de colle de fixation (11) de la fibre et d'autre part un dispositif géométrique simple de centrage de la fibre dans son embout, la précision du centrage étant due à la précision de ce dispositif et indépendante de la précision de l'embout. Utilisation dans les systèmes de transmission de données par fibres optiques.

Title: Methode et appareil d'agglutination de feuilles
Inventor: GRAM OLE
IPC: B42C9/00
Filed: 1979-10-26
Abstract: Methode d'agglutination d'une pluralite de feuilles (2), plus particulierement des feuilles de papier, empilees. Un mecanisme de poinconnage (1) possede un canal, au travers duquel une colle fondue ou dissoute peut etre introduite, et decoupe dans la pile un trou de coulee (9). Cet orifice a une forme en U; les incisions dentelees ou striees presentent a chaque feuille une ou plusieurs langues (10) qui sont pliees par rapport a leur position normale a cause du mouvement descendant du mecanisme de poinconnage, en meme temps que la colle est introduite dans le trou. Le retrait du mecanisme de poinconnage provoque le repli des langues qui reprennent leur position d'origine et effectue l'introduction de la colle entre les feuilles individuelles et ainsi que leur agglutination. Appareil pour mettre en application la methode de l'invention. L'appareil comprend un support (3) pour tenir une pile de feuilles (2) et un mecanisme a couper (1) dont une face extreme (13) possede une section angulaire ou striee. Ledit mecanisme de coupe possede un arbre creux (6) et des moyens (14, 15, 17, 18, 19) pour deposer de la colle sur les langues poinconnees. En outre, l'appareil possede des moyens (12, 16) pour remettre les langues pliees vers le bas dans leur position d'origine, apres application de la colle sur les langues et retrait du mecanisme de poinconnage.

Abstract: Un dispositif de dialyse possede un assemblage a membrane (14) comprenant deux conduits en forme de U partiellement definis et separes par une paroi constituee par une membrane de transfert. Les parois des conduits sont pourvus de sillons inclines par rapport au sens de l'ecoulement au travers du conduit. Le sang est pompe au travers d'un conduit par une pompe a gallet (16) monte en seve avec une pompe alternative (18) et le dialysat est pompe dans le sens contraire au travers de l'autre conduit par une pompe a galets (23) montee en serie avec une pompe alternative (25). Les pompes alternatives (18, 25) sont fonctionnent en phase de sorte que la composante de pulsation resultante dans les deux conduits soit en phase. Ce debit de pulsation, en association avec les sillons, produit des turbulences et un bon melange du sang et du dialysat dans leurs conduits respectifs et par consequent ameliore le contact de chacun de ces liquides avec la paroi de la membrane de transfert.

Inventor: KEEFE GEORGE EDWARD
IPC: G11C19/08
Filed: 1980-11-18
Abstract: Guard rails are described for particular use with magnetic bubble domain chips using contiguous propagation elements. These guard rails generally surround the active device area (storage area 12) of the chip (10) and are used to move stray bubble domains from the storage area to the edge of the chip, orto a collapser, and also to prevent stray bubbles from entering the active device area. These guard rail structures are comprised of contiguous propagation elements characterized by an undulating edge (28) and a smooth edge (30), both of which generally move bubble domains away from the active device area in response to the reorientation of the magnetic drive field (Hxy). In one embodiment, the guard rail is a spiral structure (14) surrounding the active device area, having one end in the interior of the magnetic bubble chip (10) adjacent to the active device area (12), and another end near the edge of the chip, or near a bubble annihilator, etc. In another embodiment, the guard rail is comprised of a plurality of structures (26) generally defining a broken-spiral which surround the active device area (12). One end of each of these structures is located near the active device area, while the other end is disposed toward the edge of the magnetic bubble chip. In the case of ion implanted contiguous propagation elements, the mask used to define the regions of ion implantation can be used as control conductors (32-40) for the devices in the active device region. For example, this mask can be used as a transfer conductor (34,36) to move bubble domains into and out of a storage area, and can also be used as a nucleate conductor (32), and as a stretcher-sensor conductor (38,40) for detection of bubbles.

Abstract: An apparatus is provided for the interconnection of two mobile carriages which are connected by a rigid beam and guided along parallel guide rails. The apparatus permits the simultaneous and identical movement, with respect to both direction and distance, of the carriages along the respective guide rails. The apparatus comprises two generally symmetrically disposed cables, each of which is attached at one end to an end of one rail and at its other end to a diagonally opposed end of a parallel rail. Intermediate the attachment points, the cables connect the carriages by resting on and being supported by return pulleys which are integral with the carriages. Each cable thereby describes a generally Z-shaped configuration. The Z-shaped configurations are symmetrically disposed in order to cause, during the displacement of one carriage, the tensioning of one of the cables, and thereby cause the other carriage to be identically and simultaneously displaced.

Abstract: A fluorescent lamp control circuit which provides power at high frequency, for example in the order of 35 kHz, includes a push-pull oscillator circuit having two transistors (T1, T2), an inductance element (L1, L1'), and a capacitor (C1, C1') to supply the lamps (3, 3'). To prevent dangerous high voltages upon removal of the lamp load, connected to the oscillatory circuit and to the series resonance circuit, upon removal of failure of a lamp, a protective circuit is provided formed by a thyristor (TH) connected to short-circuit at least one of the transistors (T1) of the oscillatory circuit. Control energy is derived directly from the high-voltage supply by a rectifier (D1, D1') connected to the inductance (L1, L1') of the series resonance circuit, so that sufficient and reliable switching energy for the protective thyristor (TH) is always available, the firing criterion therefor being determined by the breakdown voltage of a breakdown element such as a diac (22) connected to a voltage divider (20, 21) and receiving its control voltage also from the high-voltage connection of the series resonance circuit (4) including the inductance, which also feeds the power supply capacitor (C3) for the thyristor (TH).

Abstract: A stepping motor drive circuit, where the phase windings (1, 3 and 2, 4) are magnetically coupled in pairs, comprises current chopping control circuits (23, 24) controlling the switching on/off of driving transistors (5, 6, 7, 8) each coupled to a respective winding, and circuits associated to each switching transistor 5,6,7,8 for reducing their storage times and therefore their switching losses. 
     Particularly, with reference to one switching transistor (5) the related circuit for storage time reduction comprises a capacitor (25) and a diode (45), series connected, such series being connected between a terminal of the winding (2) maghetically coupled to the one (1) associated with the switching transistor under consideration (5) and the base of such transistor (5). The circuit, as soon as such transistor (5) is controlled to switch from ON to OFF, applies a reverse voltage pulse to the base of the transistor (5) thus allowing a fast transition towards the cutoff region. 
     in such way, for high chopping frequency, besides improving the stepping motor efficiency, it is possible to use switching transistors with lower dissipable power and less expensive.
