Abstract: The rain gutter debris prophylactic system has a first panel member and a second panel member joined by a trough with drains in the bottom. The trough helps regulate water flow, discourages water accumulation on the surface or the formation of icicles on the edge of the prophylactic. The front edge of the trough forms a water accelerator. In addition the drains formed in the trough allow the prophylactic to be bent by hand to match the angle formed between the roof and the gutter without heavy equipment such as hand brakes. Multiple sections may be bent simultaneously. Finally the system combines at least three water flow management techniques, namely a first set of drain holes, pooling ridges and a curved nose to conduct water over the edge of the gutter.

Abstract: A method of producing paperboard and cartons made therefrom is described incorporating a waterproof or water resistant coating applied to the interior of the carton except for areas intended for gluing. A coating material is applied to the surface of an applicator roll, and a portion of the coating material is then removed from the roll. Contact between a paperboard web and the roll transfers coating material to the web, creating a coated surface except for an uncoated stripe. A carton may be formed from the coated web with the uncoated portion of the carton cut from the uncoated strip.

Abstract: A dental instrument includes a pneumatic pressure intensifier that supplies a handpiece having an orifice to generate a high velocity liquid jet. A pneumatic system includes valves to supply the pressure intensifier and control the output to the handpiece. A jet forming assembly includes an orifice mount in the handpiece, and a guide tube assembly secured to the orifice mount. The guide tube assembly is variably positioned to select the minimum distance from the jet orifice to the tissue target, so that the jet force may be controlled.
