Abstract: Une unité de disque contient un ensemble monobloc qui est constitué d'un moyeu, d'un dispositif de serrage et d'un logement de rotor, et est, de préférence, en plastique moulé par injection. Dans un mode de réalisation préféré, le moyeu comprend une portion (201) cylindrique creuse destinée à entourer un ensemble de paliers montés sur un arbre central, ainsi qu'un rebord (202) s'étendant à partir du milieu du cylindre et supportant un seul disque (101). Des ergots (203) de blocage élastiques saillant de la surface supérieure du rebord s'engagent dans le disque à travers le trou central de celui-ci, ils sont légèrement inclinés vers l'extérieur et sont pourvus au niveau de leur extrémité d'un taquet d'arrêt. Lors de l'assemblage, le disque est entré en force au-dessus des taquets des ergots jusqu'à ce que ces derniers soient en contact avec le disque. Les ergots, par suite de leur légère élasticité, se déforment afin de permettre au disque de glisser par dessus les taquets d'arrêt, puis ils reprennent leur forme afin de bloquer le disque en place. Les ergots centrent automatiquement le disque autour de l'axe du moyeu sans qu'il soit nécessaire d'utiliser des outils de centrage. Le moyeu sert également en tant que logement du rotor d'un moteur d'entraînement de l'axe qui fait tourner le disque. Un anneau postérieur en fer ainsi que des aimants permanents sont fixés sur le côté inférieur du rebord, au niveau du bord extérieur de celui-ci, afin de former le rotor. Un ensemble stator électromagnétique entoure l'axe du disque dans l'espace annulaire délimité par le rebord, les aimants permanents et l'anneau postérieur en fer au niveau du bord extérieur, ainsi que par la portion cylindrique du moyeu au niveau du bord intérieur.

Patent CA-2205090-A1 (CA)
Title: Ignition apparatus and method
Inventor: GUMLEY JOHN RICHARD
IPC: G05F1/16
Filed: 1995-11-17
Abstract: The present invention is predicated on the concept of increasing or amplifying the voltage across the spark gap in order to ignite the gap when required thus enabling ignition of the spark gap when required. The incremental voltage to obtain gap ignition is additive to any voltage already across the gap, and is additive irrespective of polarity. That is if a positive over-voltage pulse arrives, the main gap has an increased positive voltage. If a negative overvoltage pulse arrives, the main gap has an increased negative voltage applied.

Title: A method for coating a carbon substrate or a non-metallic substrate containing carbon
Inventor: SALITO ARMANDO
IPC: C23C4/08
Filed: 1997-11-03
Abstract: To provide a substrate consisting of carbon or non-metallic materials containing carbon with a layer of a metal having a high melting point, first an undercoat layer is applied to the substrate by plasma spraying in an inert atmosphere. The undercoat layer predominantly consists of rhenium, molybdenum, zirconium, titan, chrome, niobium, tantalum, hafnium, vanadium, platinum, rhodium or iridium. Onto that undercoat layer, a covering layer can be applied, by plasma spraying as well. In order to reduce the thermo-mechanical stress and to improve the adhesion of the undercoat layer on the surface of the substrate, the substrate is preheated prior to applying the undercoat layer. By means of such a method, carbon-containing substrates can be provided with an undercoat layer and, if required, with a covering layer quickly and reliably at low costs.

Title: Internally tin-coated copper pipe and method for coating a copper pipe
Inventor: REITER ULLRICH
IPC: C23C18/31
Filed: 1997-12-19
Abstract: A copper installation pipe having a tin coating that is applied with temperature control so as to be adherent over the entire  inner surface.   The thickness  of  the intermetallic  phase  formed at  the  transition  from the copper pipe to the tin coating is less than 20%, preferably less  than  5%  of  the  overall  coating  thickness.    In addition, a method for coating an installation pipe using chemical treatment, where the temperature of the tinning solution is selectively varied.  To ensure the smallest possible intermetallic phase at the copper surface,  one begins the tinning process at a low temperature.  This promotes the formation of a large number of uniformly distributed  nuclei  of crystallization  having  the  same orientation. The temperature is then selectively adjusted to promote  crystal  growth,  the  result  being  that  the crystals  grow  rapidly  with  the  orientation  remaining constant. One then achieves a dense tin coating having a minimal exposed surface area.
