The top surface of the shingle is also configurated to drain water away from the nails used to secure it in place, to inhibit leakage of water through the nail holes in the shingle.

Abstract: A hydroelectric device wherein a water wheel having radial paddle boards is partially submerged in a moving stream of water, and driven by the water current to operate an electric generator. The water wheel has end discs at its respective sides to block escape of water from between the paddle boards. The paddle boards are normally disposed at right angles to the current flow, but if the water current should flow faster at one side of the wheel than at the other, the ends of the boards at the slow-current side may be shifted forwardly, or the ends thereof at the fast-current side may be shifted rearwardly, having reference to the direction of current flow, in order that a portion of the water impinging against the fast-current ends of the boards will be deflected to the slow-current side. This adjustment may be made either by shifting the position of the wheel relative to the water bodily, or by shifting the paddle boards relative to the wheel.

Abstract: A furnace afterburner consisting of an elongated combustion chamber through which the exhaust effluvia of a furnace is drawn, and in which a series of sets of air jet nozzles are arranged in longitudinally spaced relation along the chamber, which inject air tangentially into the chamber to generate vortices of air and exhaust spinning in alternately opposite angular directions. The injected air may be preheated. The central core area of the chamber is filled and obstructed to prevent inefficient combustion which would otherwise occur in the "eyes" of the vortices. Damper controls are provided to induce and reinforce other variations of conditions within the chamber, such as those capable of producing better retention time, better turbulence, air-gas mix proportions and temperature, all with the purpose of providing better combustion with a high degree of controllability in a wide variety of operating conditions.
