Patent CA-2205094-A1 (CA)
Title: Wire tensioner for dynamo-electric machine coil winder
Inventor: GALASSI ROSSANO
IPC: B65H59/16
Filed: 1997-05-27
Abstract: An improved tensioner for an armature winder is provided which significantly reduces instantaneous increases in wire tension during winding or lead connection. System controls which control the drag of a hysteresis brake, monitor wire tension via a load cell, and control a dancer arm's position through limit sensors and a closed-loop proportional valve (which regulates the pressure within an air cylinder coupled to the dancer arm) are provided. These system controls significantly reduce instantaneous increases in wire tension during winding, during the start of winding, and during lead connection. A wire breakage detection device is also provided which monitors the wire during winding and signals the system controls if wire breakage is detected. Upon such detection, a rapid discharge valve discharges the air cylinder, and flyer arm rotation is halted prior to the wire becoming unthreaded from the flyer arm.
Patent CA-2206491-A1 (CA)
Inventor: HUIZENGER ROBERT
IPC: G07D5/08
Filed: 1996-09-12
Abstract: A coin detection and identifying apparatus and method, utilize three closely aligned electric coils. The center coil (L2) is actively driven by an alternating current (12) to generate a magnetic field. The two outer coils (L1, L3) are symmetrically disposed within the magnetic field and voltages are induced across the terminals of the outer coils which are indicative of the relative field strengths within the outer coils. A sample coin (C1) and test coin (C2) are interposed between the center coil and each of the outer coils to attenuate the surrounding magnetic fields. A controller (32) compares the voltages across the terminals of the two outer coils to effectively compare the likeness of the sample and test coins. A coin sensing apparatus, located downstream of the coils, provides a plurality of optic emitter-detector pairs (40) to detect the valid passages of a coin.

Title: Metallic glass alloys of zr, ti, cu and ni
Inventor: JOHNSON WILLIAM L
IPC: C22C45/10
Filed: 1996-02-08
Abstract: At least quaternary alloys form metallic glass upon cooling below the glass transition temperature at a rate less than 103 K/s. One group of such alloys comprise titanium from 19 to 41 atomic percent, an early transition metal (ETM) from 4 to 21 atomic percent and copper plus a late transition metal (LTM) from 49 to 64 atomic percent. The ETM comprises zirconium and/or hafnium. The LTM comprises cobalt and/or nickel. The composition is further constrained such that the product of the copper plus LTM times the atomic proportion of LTM relative to the copper is from 2 to 14. The atomic percentage of ETM is less than 10 when the atomic percentage of titanium is as high as 41, and may be as large as 21 when the atomic percentage of titanium is as low as 24. Furthermore, when the total of copper and LTM are low, the amount of LTM present must be further limited. Another group of glass forming alloys has the formula: (ETM1-xTix)aCub(Ni1-yCoy)c, wherein x is from 0.1 to 0.3, y.c is from 0 to 18, a is from 47 to 67, b is from 8 to 42, and c is from 4 to 37. This definition of the alloys has additional constraints on the range of copper content.

IPC: H04B1/707
Filed: 1997-08-21
Abstract: L'invention porte sur une méthode et un système de détection d'un signal d'usager dans un réseau AMCR.  Les bits d'un message d'usager (codé) sont rassemblés en groupes successifs.  Une phase différentielle est générée pour chaque groupe de bits de message en mappant chacun de ces derniers à une constellation PSK prédéterminée.  Une phase absolue est générée pour chaque groupe de bits de message selon la phase différentielle du groupe de bits de message actuel et selon la phase absolue du groupe de bits de message précédent.  Le signal de phase absolue module en phase une porteuse RF pour former un signal RF.  Ce dernier est étalé au moyen de deux séquences programmées, puis transmis.  Le récepteur reçoit et démodule de façon non cohérente le signal RF qui est désétalé au moyen des séquences programmées.  Des blocs successifs du signal RF démodulé et désétalé sont comparés en phase afin d'extraire le signal de phase différentielle portant le message d'usager (codé).

Abstract: The present invention concerns a process for producing dispersions of water-soluble vinyl polymers and a stabilizer for carrying out this process. Such water-soluble, particularly cationic vinyl polymers, are employed on a large scale as process expediters for carrying out, for instance, separating processes in water treatment or waste water purification, respectively, in the paper, coal and ore industries, in oil production or also in the food stuff industry, among others, for floculation, coagulation, retention or dewatering. According to the present invention, water soluble vinyl polymers are homo- or copolymerized in the presence of a dispersion stabilizer of the invention. The stabilizer consists of a graft copolymer whose backbone is formed by polyethylene oxide and its grafted branches of cationic vinyl monomers. Among others, cationic, hydrophobically modified vinyl monomers can be advantageously employed. Copolymerizations can be carried out between cationic or non-ionic hydrophobically modified vinyl polymers and cationic or non-ionic, non-hydrophobically modified vinyl polymers.
