Patent CA-2081809-A1 (CA)
Inventor: VOISINE JOHN T
IPC: G01R11/067
Filed: 1992-10-30
Abstract: A current sensing device includes a secondary coil positioned within the curved portion of a U-shaped primary conductor or coil.  The secondary coil is surrounded by a non-ferromagnetic metallic shield to prevent capacitive coupling between the windings of the secondary coil and other nearby metallic objects.  A nonconductive material is integrally formed about the U-shaped conductor and provides a cavity for receiving the secondary coil and shield in a predetermined position with respect to the U-shaped conductor.  A flux guide of ferromagnetic metal, formed in an elliptical-cylindrical shape, surrounds the U-shaped conductor and the secondary coil to provide a flux steering effect to steer flux around the secondary or pick-up coil. The current sensing device is useful in measuring current in electrical utility power monitoring or watthour meter applications.

Patent CA-2101885-A1 (CA)
Inventor: ABE NAOKI
IPC: B01D21/00
Filed: 1993-08-04
Abstract: A method of separating an aqueous colloidal solution by agglomeration into water and agglomerate of colloidal particles by applying voltage to the aqueous colloidal solution to promote the agglomeration of colloidal particles.  The frequency of the voltage to be applied to the aqueous colloidal solution is increased to about 10kHz to improve efficiency of agglomeration and suppress electrolysis of water.  As the frequency is increased, hydrogen is generated earlier than the reaction of oxygen generated by the electrolysis of water with the colloidal particles, thus not oxidizing the colloidal particles.          Further, as the frequency is increased, the colloidal particles tend to obtain a greater oscillation energy, thus facilitating the agglomeration thereof.
