Patent CA-2049755-A1 (CA)
Inventor: RAGGIO WILLIAM A
IPC: B65H59/38
Filed: 1991-08-23
Abstract: A system for maintaining a predetermined tension of a wire has a rotatable wire supply spool, a motor-driven wire take-up spool, a motor-drive wire feed spool. The wire is wound around the supply spool and is also attached to the take-up spool. The wire also passes partially around the feed spool and a pulley or guide which is attached to a pivot arm.      The pivot arm is positioned between the take-up spool and the supply spool. A frictional layer is disposed around the outer circumferential surface of the feed spool, to prevent the wire from sliding across the frictional layer of the feed spool.      The elongated pivot arm that has its free end positioned against the wire. The pivot arm pivots in response to the differences in speed between the supply and take-up spool. A motion sensor detects motion of the pivot arm and generates a control signal in response. The control signal is electrically conducted to a stepper motor. The stepper motor is electrically connected in turn to the feed spool to establish the speed of rotation of the feed spool and thereby match the supply spool speed with the take-up spool speed.      The pivot arm can be weighted and oriented at an angle different from its rest position angle to establish the desired tension on the wire.

Abstract: L'invention concerne un procédé d'élimination du mercure sur l'ensembled'une installation de vapocraquage, caractérisé en ce que la régénération se termine par l'injection du gaz de régénération sur l'une des masses actives démercurisantes, de telle sorte qu'il n'y ait substantiellement aucune trace de mercure dans l'air ou dans les liquides sortant de ladite installation. A titre d'exemple le procédé comporte l'utilisation de trois masses démcercurisantes, à savoir: deux en amont de l'installation, en série (masse 1 et masse 2), et une en aval (masse 3), qui est démercurisée par au moins une des masses en amont. L'utilisation s'applique en particulier à la dépollution d'installations de vapocraquage déjà polluées par le mercure.

Title: Method for treatment of zinc-containing by-products and waste materials
Inventor: AUNE JAN A
IPC: C22B7/04
Filed: 1991-11-15
Abstract: ABSTRACT     The present invention relates to a method for treatment of zinc-containing by-products and waste materials from primary and secondary production of nonferrous metals and especially zinc- and leadcontaining slags from the production of lead. The by-products and the waste materials are supplied to a gastight closed electric smelting furnace in which the materials are melted and subjected to a selective metallothermic reduction in order to reduce and volatilize zinc and other volatile metals. Elemental sulphur and/or sulphur compounds are added to the smelting furnace in an amount sufficient to form a sulphide phase containing one or more of the elements Cu, Ni, Pb, As, Bi, Sb and Ag. An inert slag phase and the sulphide phase are tapped from the furnace, and zinc and other volatile metals are recovered from the off-gas from the furnace by condensation.

IPC: G01N1/22
Filed: 1991-11-25
Abstract: A process for the continuous analysis of trace contaminants in a process gas of O2, N, Ar or H2.  A sample of the process gas is passed through a plurality of analyzers with each dedicated to detect the presence of a predetermined trace contaminant and to provide an output signal corresponding to the level of trace impurity detected.  A status signal is generated representative of preselected parameters of analyzer operation.  The output and status signals are converted by a computer into data values.  A rule based program provides a problem analysis to identify distinct problems based on the examination of the data values.  The rule based program is executed by a separate command program which matches the problems identified by the rule based program with remedial actions to remedy erroneous conditions of analysis.

Title: Prime mover
Inventor: KANAZAWA YUKIO
IPC: H02K53/00
Filed: 1992-02-17
Abstract: ABSTRACT  The object of  the  present  invention  is  to provide a prime mover by which rotary force can be obtained only with magnetic actions of a magnet. The first rotary body provided with the second magnetic body can be driven and rotated as  the second magnetic body is attracted by the first magnetic body attached to the inner circumferential face of the body base which is in a stationary state. And When the second magnetic body passes through a position confronted to the first magnetic body, the second magnetic body is covered up with the magnetic control member on the second rotary body which is driven and rotated under such a condition as the speed thereof is accelerated for the first rotary body by the first rotary body. As a result, the magnetic action  of  the  first magnetic  body  is  not exerted on the second magnetic body.  The above state  is repeated by turns at each of  the portions divided in the axial core direction of the prime mover, thereby causing the rotation of the prime mover to be maintained.

Title: Method and device for the selection of an insole and/or a shoe that adjusts the posture of the foot
Inventor: HYVAERINEN TUOMO
IPC: A43D1/02
Filed: 1992-04-15
Abstract: ABSTRACT    The invention is related to a method for the selection of an insole and/or of a shoe that adjusts the posture of the foot and for determination of the biomechanical mode of operation of the foot.  In the method, the determination of the mode of operation of the foot is carried out by placing the foot on a symmetry axis of a measurement base, and the load thus applied by the measurement base to a rigid support base in relation to the symmetry axis of the measurement base is measured.  For the measurement, the supposed symmetry axis of the foot to be measured is aligned with the symmetry axis of the measurement base by guiding the position of the foot onto said symmetry axis by the heel and by the toes.  The measurement of the load is carried out preferably in two stages so that first the load is measured when the person stands on the measurement bases with straight legs, and thereafter the load is measured when the knees have been bent substantially 45° from the straight posture.  The invention also concerns a device intended for carrying out the method.
