John J Daniels has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: The present invention relates to an apparatus designed to launch a sailboard out of the water while the sailboard is being sailed on the water. The apparatus comprises launching means including a flap which is submergible in the water and pivotally supported at one end of the flap near the bottom of the sailboard. An angle of attack of the flap relative to the water is varied by a positioning means. The submerged flap is thus presented at an oblique angle to the incompressible water which thus acts as a ramp to launch the sailboard out of the water. In an alternative embodiment, a hydrofoil wing acts to lift the sailboard relative to the water surface.
Abstract: A tension responsive fishing apparatus is provided which includes a pole member having an interior. The interior of the pole member is filled with a variable viscosity fluid, such as, electrical rheological fluid, magnetic-powder dispersed fluid, or the like. A controlled potential may be applied to the variable viscosity fluid which causes the variable viscosity fluid to vary in viscosity dependent on the amount of potential applied thereacross. In other words, depending on the amount of potential applied to the variable viscosity fluid disposed in the interior of the pole member, the flexure of the pole member may be selectively varied from extremes of high flexibility to high rigidity. An improved reel member is provided which varies a resistance applied to a bobbin member which is effected to control the release of fishing line. The varying resistance is controlled in response to input signals inputted dependent on tension sensed in the fishing line and/or a value selected by a user.
Abstract: A conventional mirror will quickly fog when exposed to the extremely humid environment of the shower. This is because the moisture contained in the warm ambient air condenses on the relatively cooler mirror surface. An effective way to remedy this problem is to heat the mirror surface to a sufficient temperature to combat condensation of the moisture in the ambient air. This invention provides an effective method and apparatus to combat fog formation. This invention utilizes relatively simple construction to provide a low cost, safe, highly portable, efficient and effective method and apparatus to provide a non fogging shower mirror. To achieve this, the inventive device (10) incorporates a mirror, attached to a reservoir (14). This reservoir (14) holds a thermal mass of warm water.
Abstract: A high-pressure discharge lamp comprising a discharge vessel (3) enclosed by an outer envelope (1) provided with a neck (10) which is adjoined by a sleeve (20) of a lamp cap (2). The lamp cap (2) accommodates an electrical circuit provided with a semiconductor switching element (26) which controls the discharge current in the operating condition of the lamp. The semiconductor switching element (26) is provided with a cooling member (24) which is preferably secured to the sleeve (20). This lamp may be used without further expedients in combination with a stabilization ballast not adapted to the lamp.
