Patent CA-2430022-A1 (CA)
Inventor: FECERA FRANK J
IPC: H02K53/00
Filed: 2001-10-26
Abstract: A motor providing unidirectional rotational motive power is provided. The motor has a generally circular stator with a stator axis, an outer surface, and a circumferential line of demarcation at about a midpoint of the outer surface. The motor also includes one or more stator magnets attached to the outer surface of the stator. The stator magnets are arranged in a generally circular arrangement about the stator axis and generate a first magnetic field. An armature is attached to the stator for rotation therewith, the armature having an axis parallel to the stator axis. One or more rotors, are spaced from the armature and coupled thereto by an axle for rotation about an axis of each rotor, each rotor rotating in a plane generally aligned with the armature axis. Each rotor includes one or more rotor magnets, with each rotor magnet generating a second magnetic field. The second magnetic field generated by each rotor magnet interacts with the first magnetic field to cause each rotor to rotate about the axis. A linkage assembly drivingly connects each rotor to the stator to cause the armature to rotate about the armature axis thereby providing the unidirectional rotational motive power of the motor.

La cathode présentant un dépôt est acheminée vers un fourneau de production de silicium (Si), le dépôt renfermant Si sur la cathode s'écoule vers le fond du fourneau et ladite cathode est retirée avant la fusion de Si dans le fourneau. De manière alternative, le dépôt présent sur la (les) cathode(s) est placé sur le fond du bain, le bain fondu ou le bain figé renfermant Si à partir du dépôt de la cathode est transféré vers un fourneau Si après l'écoulement de l'aluminium vers le fond du fourneau d'électrolyse et le retrait dudit aluminium. Selon ce procédé, le silicium présent dans le dépôt sur la cathode et/ou dans le bain fondu ou figé est fondu et séparé des scories par l'écoulement du silicium fondu vers le fond du fourneau Si. Ensuite, les scories sont agitées profondément dans le bain de silicium, puis les scories et le bain Si se séparent directement. Ces scories sont retirées du bain Si et le silicium est soumis à une opération de rectification cristalline.

Inventor: LALUMIERE REJEAN
IPC: F25B39/02
Filed: 2003-10-22
Abstract: An evaporator is provided having first and second independent evaporator coils. The evaporator is for use in a refrigerated display case, either open or closed, having a display length. Each of the evaporator coils is co-extensive along the display length.  The evaporator coils are alternately defrosted and cooled in such a manner as to maintain a substantially constant cooling temperature throughout the refrigerated display case, even during a defrost cycle. An independent set of cooling fins is mounted to each of the evaporator coils for absorbing heat when a refrigerant, either liquid or gas, is circulated and evaporates in the evaporator coils, thus cooling the display case. A separate return is provided for each separate evaporator coil, though the two returns preferably join into a common return, thereby facilitating maintenance of a substantially constant cooling temperature.

Abstract: An electrical power control apparatus and method for a conventional 60 hertz or other conventional frequency electrical AC power supply voltage waveform to prove an effective output current and voltage to an intended load whereby the output frequency is the same as the input frequency. Using a switching means (16) capable of micro switching the current on and off, and a plurality of substantially equal length and duration interruptions of current on both sides of an AC current oscillation, the output effective voltage and resulting current may be preset and controlled to a pre-programmed output level regardless of input voltage having one or more phases. Or, the output voltage and resulting current may be continually monitored with the load (22) integrated into the circuit being monitored and continually adjusted to yield maximum power use savings while avoiding damage to the components attached to the circuit. Additional embodiments provide for use of the micro chopping device as a circuit breaker (32) for over current protection and as a smart circuit breaker to yield a data stream on individual circuit power usage which can be communicated to a monitoring station locally or by electronic transmission of information to a remote monitoring station. Real time monitoring and adjustment of power usage may be accomplished using such communication and two way communication between the device and communicating monitoring station also allow for real time charges for power usage and deduction from prepaid account for real time power usage.

Title: Process for producing polyurethane moldings
Inventor: GRINSTEIN OLIVER
IPC: B29C67/24
Filed: 2004-02-10
Abstract: Polyurethane moldings are produced by conveying in shot operation at least one isocyanate component and at least one polyol component for a predetermined time-interval .DELTA.t into a mixing chamber with predetermined volumetric flow-rates ~ s/iso for the isocyanate and ~ s/polyol for the polyol and with predetermined pressures p s/iso for the isocyanate and p s/polyol for the polyol, mixing those components in a mixing chamber, and discharging the polyurethane reaction mixture into a mold. Prior to shot operation, the components are conveyed in a circuit through circulation lines between the mixing head and the respective component storage vessels. The pressures of the components are measured by means of pressure sensors and are transmitted via pulse lines to a control device. During conveyance in the circuit, the volumetric flow-rates of the components are adjusted in such a way that the pressures of the components in the circuit correspond to the predetermined pressures p s/iso and p s/polyol of the components for shot operation. During the change-over from circulatory mode of operation to shot operation, the predetermined volumetric flow-rates ~ s/iso and ~ s/polyol of the components are adjusted for shot operation. The adjustment of the volumetric flow-rates of the components may be effected by the control device by adjusting the drive units of the metering elements.
