Abstract: What is disclosed are embodiments of magnetic torque transfer devices utilizing torque transfer by magnetic induction in which an induction cylinder fabricated from an electrical conductor is interposed into the gap between a pair of magnetically coupled primary and secondary rotors. Rotation of the induction cylinder relative to the coupled rotors evokes magnetic torque transfer in accordance with Lenz's Law. The primary rotor rotates within a toroid shaped stator. The stator may be configured for rolling biphasic coil control. The secondary rotor is attached to a propeller. The device may function as a turbine when fluid is directed to flow over the propeller. The device may function as a pump when AC power is supplied to the stator. Rolling biphasic motor control includes dividing motor coils into increments, then configuring groups of contiguous increments into virtual coils, which revolve in tandem with the primary rotor so to achieve continuous and optimal torque transfer with minimum torque ripple.

Abstract: The present glass cleaning tool is a small, handheld, easily stored device having a self-contained supply of cleaning fluid stored therein and an applicator head for applying the fluid to a glass surface. The applicator head is stored within the storage handle of the device when the device is not in use. An attachment mechanism extends between the storage handle and the applicator head to secure the head to the handle and to allow the head to be extended from its storage location within the handle to its deployed position across the end of the handle, with the handle and head forming a T-shaped configuration. The device is particularly well-suited for carriage in an interior storage area of a motor vehicle for use in cleaning cigarette smoke film, fingerprint smears, and other contaminants from the interior of the windshield and other glass surfaces in the vehicle.
