  • Publication number: 20230381685
    Abstract: A system and method for extracting and separating botanical oils and compounds from botanical material without the use of solvents, having a vaporizing section which is further coupled to a centrifugal electrostatic precipitator for collection and segregation. The vaporizing section receives the botanical material through which a temperature-controlled inert gas is passed to evaporate specific vaporization temperature oils or compounds from the botanical material. The extracted vapor passes to the centrifugal electrostatic precipitator where the oil or compound is reduced back to the liquid state and is collected and segregated. The oils having the lower vapor temperature are collected first and the remaining oils are collected by specific and progressive vaporization temperature control.

  • Patent number: 8072113
    Abstract: The electric machine comprises a rotor and stator, the rotor and stator having generally equal axial lengths. The stator has at least one primary and at least one control winding disposed around the stator. The electric machine comprises a stator extension of a magnetic material. The stator extension is disposed coaxially with the stator and has only the at least one control winding wrapped therearound. The stator extension extends axially adjacent the stator beyond an axial terminus of the rotor and defines a magnetic circuit around the at least one control winding. The stator extension is configured such that in use, the magnetic circuit remains unsaturated thereby increasing inductance of at least one control winding in an electric alternator/motor.

  • Publication number: 20110192646
    Abstract: Matrices of multiple cast conductors, and methods for making such matrices. Methods according to the disclosure comprise: casting a conductor matrix including a plurality of conductors joined by at least one link; applying a surface treatment to at least a portion of the matrix; finishing a contact face on at least one of the conductors; and separating the conductors from each other at the at least one link.
