  • Patent number: 10781603
    Abstract: A mast raising assembly includes a base that is securable to a horizontal support surface. A tube is insertable into the base such that the tube is vertically oriented. A winch is coupled to the tube and a pair of lower pulleys is each rotatably coupled to the tube. A mast is pivotally coupled to the tube. The mast is positionable in a raised position and a folded position. A plurality of upper pulleys is each of the upper pulleys is rotatably coupled to the mast. A cable extends between the winch, the lower pulleys and the upper pulleys. The cable urges the mast into the raised position when the winch is rotated in a raising direction. Additionally, the cable urges the mast into the folded position when the winch is rotated in a lowering direction.

  • Patent number: 8992848
    Abstract: The present invention relates to a delivery apparatus for delivering electromagnetic energy into a solution. The delivery apparatus comprises a coil means arranged within an outer housing for delivering a magnetic field into the solution, a voltage assembly means coupled to the coil means for delivering an electric field into the solution, and connection means for delivering an electromagnetic signal to the coil from electromagnetic signal generation circuitry contained within the housing. The arrangement of the present invention confers significant physical stability on the delivery apparatus and ensures that heat generated by heat generating components of the apparatus is conducted away from the electromagnetic signal generation circuitry so that the apparatus can be operated continuously.
