Abstract: A downdraft gasifier that utilizes a plurality of vertically positioned tubes to create a pyrolysis zone, an oxidation zone beneath the pyrolysis zone and a reduction zone beneath the oxidation zone. The shape of the tubes eliminates the need for a restriction (hearth), which limits the maximum achievable throughput. A rotating and vertically adjustable grate is located beneath, but not attached to, the reduction zone of the gasifier.

Abstract: A method and device for protecting a power switching semiconductor inverter from thermal cycling is disclosed. The method compares the actual frequency of the inverter to a low fundamental frequency of the inverter and compares the actual current of the inverter to a continuous current rating of the inverter. A thermal cycling condition is detected if both (a) the actual frequency is lower than the low fundamental frequency and (b) the actual current is higher than the continuous current rating. A thermal cycling fault condition is detected when the inverter has been in the thermal cycling operating condition for a sufficient period of time to cause its present stress factor to exceed a predetermined rated stress factor.

Abstract: An underwater dive plane includes a central rotating hub, rotating wing holders on either side of the central rotating hub, and wings attached to the wing holders. The attachment is accomplished by a threaded bolt inserted through the center of the central rotating hub and through the center of the wing holders in a way that permits the wing holders to rotate around the threaded bolt. A rope threaded through a hole in the central rotating hub leads to a watercraft and allows towing a person holding onto the dive plane. The rotating wings allow the diver to control the angle and direction of the dive.
