Abstract: A device to measure both the fuel level in high wing aircraft fuel tanks and check for water and other impurities in the fuel tanks. This invention is used from the underside of the wing and is inserted from below into the fuel tank sump valve. The device measures both the height of the fuel within the tank to determine how full it is and at the same time drains fuel into the device for visual inspection of water and other impurities. The device can be used to determine both fuel level and impurities at the same time or separately.

Abstract: A single, relatively thin, plate with no movable parts, easily inserted between the bottom of the carburetor and the top of the intake manifold of vehicles using internal combustion engines without fuel injection systems, which plate has a plurality of wedge shaped collectors directed in a counterclockwise direction, the shoulders of one side of the wedge like collector helping to break up the fuel mixture into smaller parts with the two sides of the wedge like shaped collector forming a cup like funnel ending in the apex of the wedge like collector which points of the wedge shaped collectors form a smaller inner circumference than the outer circumference at the base of the wedges helping to funnel the liquid mixture collected into the main steam of the air current causing both greater atomization and vaporization thus increasing fuel economy while decreasing exhaust pollution.

Abstract: Bristles for a toothbrush arranged in repeating patterns of like and unlike shaped bristles, consisting of clusters of long, soft, bristles alternating with clusters of shorter, pyramidal shaped bristles which shorter bristles begin at the base of the longer clusters of bristles, together with the other two sides of the pyramid facing the width of the brush, all four sides gradually moving in a convex curve to the apex of the pyramidal bristles which is centered from all sides, allowing the bristles to be used along any portion of the teeth, either occlusal, or labial, lingual or buccal either in a horizontal motion along the teeth or in a vertical direction either up or down, which brushing facilitates not only the cleaning of the teeth and between the teeth, but also the massaging and strengthening the gingerval tissue providing both interproximal and periodontal bristles used at the same time.

Abstract: A tooth brush having a handle with brush portions on both ends. The handle is contoured in the form of an elongated "S" curve contoured to the curvature of the side rows of human teeth with contoured "bullet shaped" ends to fit the contour of the innermost recesses of the human mouth between its teeth and cheeks.
