Abstract: Renewable fuel cells that produce hydrogen gas, on demand, are used to power a vehicle. When the usable volume of hydrogen gas produced by the fuel cells is depleted, the magnesium anode is converted into magnesium hydroxide precipitate. The magnesium hydroxide precipitate is removed and collected for recycling and the magnesium anode and salt water electrolyte is replaced, thus easily and conveniently re-energizing the fuel cell. The magnesium hydroxide precipitate is recycled to recapture the magnesium which is then formed into new magnesium anodes. The primary power source for the recycling is derived from solar energy. The only waste product produced by the operation of the fuel cell is non-polluting water.

Abstract: Cleaning solvent is sprayed about the periphery of the air intake of a gas turbine engine in that area of the intake where the air speed is turbulent and relatively slow. The pattern of spray is created by a plurality of nozzles uniformly spaced about the periphery of the air intake. The nozzles each have an arm bent at an angle of approximately 30.degree. and mounted to create a spray pattern of a fan shape at an angle of 90.degree. respecting the exit aperture of the nozzle. The spray cloud thus created in the area of low speed relatively turbulent air before the compressor of the engine creates a uniform intake of cleaning fluid into the engine when the engine is operated at or near full speed and at or near full load. The 90.degree. fan shape pattern at the nozzle aperture narrows to 60.degree. when the engine reaches operating speed and load.

Abstract: A dispensing cap apparatus is provided for dispensing a fluid from a container. The cap includes a base portion and a cover cap portion which are slidably moveable with respect to each other. The base includes a cam surface and the cover cap includes a cam follower. Opening the apparatus requires squeezing opposing sides of the cover cap to move the cam follower against the camming surface which forces the cover cap into a raised position to unseal the cap and allow fluid to flow thereout. In another embodiment, a portion of the base is cammed downward with respect to their cover cap to open the apparatus. Also included as embodiments are a child-proof embodiment wherein the cover cap must first be aligned with the base before the apparatus may be opened and an embodiment wherein the camming surface and cam follower coact to prevent the cap from being closed after it has been opened.

Abstract: Benzoic acid esters of a polyalkoxylated block copolymer, i.e. PLURONICS, exhibit enhanced characteristics that make these esters ideally suited for skin and hair care compositions. These esters demonstrate enhanced capabilities as foam boosters, emollients, conditioners, clarifiers, solubilizers, and carriers (dilutents). In addition, both oxybenzone and benzocaine can be solubilized by these esters.

Abstract: Benzoic acid esters of an ethoxylated methyl glucosides and of a propoxylated methyl glucosides exhibit enhanced characteristics that make these esters ideally suited for skin and hair care compositions. These esters demonstrate enhanced capabilities as foam boosters, emollients, conditioners, clarifiers, solubilizers, and carriers (diluents). In addition, oxybenzone, benzocaine, ibuprofin and dihydroxyacetone (DHA) can be solubilized by these esters. These esters have the ability to solubilize both hydrophilic and hydrophobic materials such as DHA. The benzoate esters have lower surface tensions than the glucam polyol molecules from which they were derived.
