Chorus Motors plc Announces Chorus Motor Winding Patent

    GIBRALTAR--July 3, 2001--Chorus Motors plc, a subsidiary of Borealis Exploration Limited (BOREF), announces that a patent, titled "Method of Winding A Rotating Induction Apparatus", No. 6252324, was issued by the United States Patent and Trademark Office on June 26th, 2001. Further patent applications related to the Chorus(tm) technology and polyphase motors are pending.
    The Chorus(tm) Motor uses new controllers and windings to substantially increase the efficiency of AC motors. For more information about Chorus(tm) see the Chorus Motors plc web site at www.chorusmotors.gi. The new patent and other Chorus patents are available on the web site.
    Characteristics of the Chorus(tm) Motor include very high start-up torque and greater efficiency, within standard operating temperature limits. Tests have shown marked improvements over conventional AC motors. The technology was recently featured by Mechanical Engineering magazine, www.memagazine.org/mepower01/5thharm/5thharm.html.
    The patent describes a new and compact method of winding copper wire around the stator of an electric motor to produce a polyphase motor with the characteristics required for the Chorus(tm) technology.
    Isaiah W. Cox, President of Chorus Motors plc, says "This is the first really novel winding process in two decades. These windings, together with our proprietary control system, make the Chorus (tm) motor the ideal solution for many industrial applications, including traction motors and electric or hybrid-electric vehicles."
