Chorus Motors plc Announces Chorus Motor PWM Patent.Business Editors GIBRALTAR--(BUSINESS WIRE)--Feb. 25, 2002 Chorus Motors plc, a subsidiary of Borealis Exploration Limited Borealis Exploration Ltd. is a Gibraltar-based research and development company that owns subsidiaries dealing with materials and power transfer. The company considers itself a virtual company, and is publicly traded. (BOREF), announces that a patent, titled "Drive Wave Form Synchronization For Induction Motors", No. 6,348,775, was issued by the United States Patent and Trademark Office The United States Patent and Trademark Office (PTO or USPTO) is an agency in the United States Department of Commerce that provides patent protection to inventors and businesses for their inventions, and trademark registration for product and intellectual property on February 19th, 2002. Further patent applications related to the Chorus(R) technology and polyphase Pol´y`phase a. 1. (Elec.) Having or producing two or more phases; multiphase; as, a polyphase machine, a machine producing two or more pressure waves of electro-motive force, differing in phase; a motors are pending. The Chorus(R) Motor uses new controllers and windings to substantially increase the efficiency of AC motors. For more information about Chorus(R) see the Chorus Motors plc web site at www.chorusmotors.gi. The new patent and other Chorus(R) patents are available on the web site. Characteristics of the Chorus(R) Motor include very high start-up torque and greater efficiency, within standard operating temperature limits. Tests have shown marked improvements over conventional AC motors. Chorus(R) Motors are especially well-suited to traction applications, such as hoists, conveyors, electric and hybrid-electric vehicles. The patent describes a new technique for pulse width modulation See PWM. (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) in which the PWM, which normally degrades the performance of conventional 3-phase motors, does not degrade the performance of a Chorus(R) drive. The technique makes special use of the tolerance Chorus(R) drives have for harmonic content to use PWM without energy losses due to pulsation pulsation /pul·sa·tion/ (pul-sa´shun) a throb, or rhythmic beat, as of the heart. pul·sa·tion n. 1. The act of pulsating. 2. A single beat, throb, or vibration. , something that 3-phase motors cannot do. Isaiah W. Cox, President of Chorus Motors plc, says "This patent broadens our coverage of the core Chorus(R) technology, helping to seal our dominant technical lead in high phase order drive. As Chorus(R) products enter the marketplace, patents like these ensure that the technology remains proprietary, and under the control of Chorus Motors plc." Borealis Exploration Limited has 5,000,000 shares outstanding. Borealis' business is reinventing the core technologies used by basic industries, including electric motors, steelmaking, electrical power generation, and cooling and refrigeration refrigeration, process for drawing heat from substances to lower their temperature, often for purposes of preservation. Refrigeration in its modern, portable form also depends on insulating materials that are thin yet effective. .
