Abstract: A sail having a built-in-pocket and its method of construction is disclosed. A sail having foot and luff measurements and a desired angle at the finally formed tack is formed from sail material and has a built-in-pocket at a desired location. In forming the sail, the luff is pivoted forwardly on sail material about its upper edge to a sail forming position and the foot is pivoted downwardly on sail material about its rearward edge to a sail forming position; the amount that the bottom edge of the luff is moved forwardly determines the depth of the pocket; a first edge is formed between the moved end of the luff and a desired point providing the location of the center of the pocket; a second edge, equal to the first edge, is formed between the moved end of the foot and the desired point, the mating edges are fixed together, such as by sewing.

Abstract: A solar water heating system for heating water in a solar panel and storing it in a water storage tank includes a pump which circulates the water in the system, from the water storage tank through the solar panel and back to the water storage tank; a freeze protection means permits water to bleed off from a location between the solar panel and water storage tank when the pump is off to maintain a flow of water through said solar panel and connecting parts thereof which are located in an area where freezing can be encountered. Means are provided to turn the pump on and off and a backup heating device is located in the water storage tank, such as an electrical heating unit, to provide heat when there is not sufficient solar energy.

Abstract: An afterburner on a turbofan or fan-jet engine contains a fuel system having a fuel control delivering fuel to a plurality of injection zones. As the power lever is advanced, for afterburner operation, fuel is delivered sequentially to the afterburner through different zones until it reaches the last zone. The last zone comprises a set of two axially spaced sprayrings located adjacent the outer wall of the afterburner, one spraying being located upstream of the other spraying. The downstream sprayring has a splash plate located radially inwardly from each nozzle to provide a barrier to the fuel spraying inwardly for directing a portion of the spray downstream over the outward radial portion of the afterburner near the afterburner wall.

Abstract: An apparatus is set forth for the continuous production of highly cooled metal splats. Melted metal is poured onto a spinning atomization disc means whereby liquid metal droplets leave the disc means in a horizontal plane. An annular cooling gas jet flowing normal to the particle plane around the disc deflects the heavier liquid droplets to a conical splat plate which is fixed to rotate with said disc, where the droplets splat and cool, and are ejected by centrifugal force. An annular space is located between said conical splat plate and said rotary atomization means for permitting the gas and other solidified particles to pass downwardly to a shield which directs the particles to a collection area.

Abstract: A sprinkler head has a pop-up riser having a nozzle at the upper end thereof for directing a desired flow of fluid therefrom; the riser contains a turbine drive device for rotating the nozzle in response to fluid passing through the sprinkler head; the nozzle having a sealing surface with a part of the sprinkler head; the nozzle being biased against the part so that fluid passing through the nozzle decreases the force biasing the nozzle against the non-rotating part. A modification of the nozzle and turbine drive is disclosed. The modified nozzle is biased against the non-rotating part at a predetermined sealing load which has a minimum effect by the pressure of the fluid flowing through the nozzle. The turbine drive has a gear drive housing filled with fluid and sealed from contact with the fluid passing through the sprinkler head by a capillary tube.
