Abstract: A spinal jack adapted for installation between first and second vertebral processes and including an upper spinal jack body and a lower spinal jack body having gripping portions adapted for engaging the vertebral processes. A pair of upwardly extending sleeves are integrated into the lower spinal body and coaxially receive a pair of downwardly extending stems integrated into the upper spinal body. A pair of spring actuated and stepped pins are incorporated into the lower jack body and, when inwardly actuated, engage recessed locations configured along the stems in order to define an adjusted separation distance between the bodies. In a second variant, a rotatable gear is incorporated into one of the bodies and engages a pair of outer beveled gears, with additional gears actuated by the outer bevel gears and in turn engaging any of opposing teeth or threads configured into the extending stems in order to define an adjusted separation distance between the bodies.

Abstract: A multi-stage fluid conditioning system having a housing with a fluid inlet and outlet. A shaft extends within the housing and supports a first fan unit with a first magnet/electromagnet plate on an inlet side of said housing and a second fan unit with a second magnet/electromagnet supporting plate on an outlet side of the housing. Each of the first and second magnet/electromagnet supporting plates include at least one vane configured to direct fluid flow. The shaft rotates the plates in order to draw a fluid flow through the inlet and successively across the inlet and outlet sides for thermal conditioning resulting from creation of high frequency oscillating magnetic fields according to a succeeding conditioning operations before being outputted the conditioned fluid from the housing through the fluid outlet.

Abstract: A fluid thermal conditioning (heating/cooling) system including a housing containing a fluid holding tank and having an inlet pipe and an outlet pipe. A drive shaft rotatably supports either of a conductive plate or a plurality of spaced apart magnetic or electromagnetic plates positioned within the housing. The conductive plate can be reconfigured as an elongated conductive component supported within the housing and including a plurality of individual plates which alternate in arrangement with axially spaced and radially supported magnetic/electromagnetic plates. Upon rotation of the shaft, an oscillating magnetic field is generated for thermally conditioning the fluid.

An elongated conductive component is rotatably supported about the sleeve support and includes linearly spaced apart and radially projecting conductive plates which alternate with the spacing established by the magnetic or electromagnetic plates. A motor rotates the conductive component which, upon rotation of the conductive plates, generates magnetic fields to condition the fluid according to either of induction heating or cooling. The rotating plates of the conductive component are further individually configured so that they simultaneously redirect the conditioned fluid flow through a warm air outlet of the housing.

Abstract: A method of controlling a wind turbine transformer is provided. The transformer has a primary side with a primary winding coupled to a power grid and a secondary side with a secondary winding coupled to an electrical power generating system of the wind turbine. The wind turbine transformer further includes an electronic on-load tap changer having semiconductor switches that are controllable to change a turns ratio of the primary winding to the secondary winding of the wind turbine transformer. The method includes the step of monitoring a voltage on the primary side of the wind turbine transformer, a voltage on the secondary side of the wind turbine transformer, or both. In response to detecting a change in the monitored voltage, the semiconductor switches of the electronic on-load tap changer are automatically controlled to adjust the turns ratio of the wind turbine transformer to compensate for the change.
