Title: Electric drive system, in particular for vehicles
Inventor: WECK WERNER
IPC: B60L3/00
Filed: 2001-12-11
Abstract: In order to enhance the operational reliability of an electric drive unit of a vehicle comprising a generator (G), which is operated by an internal combustion engine (V), and drive motors (M1, M2), which are connected to said generator via a d.c. link, the generator and drive motors are subdivided into partial units (TG1, TG2; TM11-TM22), and power electronics units (TGLE1, TGLE2; TM1LE1, TM1LE2...) are assigned to these partial units. The partial units, which correspond to one another and which consist of the generator, motors and of power electronics units, each form a separate drive circuit (AK1, AK2) whose components are supplied with control signals by a specifically assigned system control unit (1, 2). The system control units (1, 2) that are interconnected via an information exchange channel (IAK) can undertake compensation measures in their drive circuit or in the other drive circuits in the event of a complete or partial failure of a drive circuit (AK1, AK2). Alternatively to the assignment of one system control unit (1, 2) at a time to a drive circuit, several system control units can also be connected to the individual drive circuits via bus connections or via multiple single channels.

Patent CA-2458353-A1 (CA)
Title: Method of adhesive bonding by induction heating
Inventor: MALOFSKY BERNARD M
IPC: H05B6/06
Filed: 2000-11-02
Abstract: An apparatus and system for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, resins, or composites so as to reversibly or irreversibly bond, bind, or fasten opaque or non-opaque solid materials to one another. The system makes use of the effect that alternating magnetic fields induce eddy currents and generate heat within susceptors, and the effect that alternating magnetic fields additionally induce magnetic hysteresis that occurs in magnetic materials and thereby generate heat. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The distance between the susceptor and work coil is repeatedly analyzed based upon the power converter's input energy, and the work coil is driven at a repeatedly corrected power level during the heating cycle. Once a sufficient accumulated energy has been delivered to the susceptor, the magnetic field is turned off automatically by the tool, thus preventing overheating of the susceptor.
