Abstract: A refillable container includes a filling valve, and a pressurization station having housing at which a needle is coupled to a compressor. The needle includes an enlarged frustoconical head, a reduced diameter neck, and a larger diameter base. The filling valve has an upper split portion, a frustoconical section expanding downward and terminating in a barb, and a lower flared flange, and defines an interior space having a first portion sized to accommodate the head of the needle, a reduced diameter neck portion, and a flared third portion providing an entrance for the needle.

Abstract: A method and apparatus (10) for custom blending spray paints. A customer provides a sample (S) of a color to be matched. The sample is tested on a spectrophotometer to determine the colors needed to match the sample; or if the paint formula is known, it is entered into the apparatus. A computer control (16) causes metered quantities of each colorant to be pumped from a reservoir (50) to a manifold (68). From the manifold, paint is injected through a filling head (46) into a discharge valve (V) and dip tube (P) of a precharged aerosol container (C) to be filled. Solvent from a tank (74) is used between a final injection of colorant to flush out the manifold and a dip tube (P) of the container. After the colors have been injected into the container, the container is shaken so that the colors intermix with each other to produce a paint of the desired custom color which is readily sprayed from the container.

Abstract: Prior research into methane storage as a solute gas dissolved in special blended hydrocarbon liquids, and recent developments in use of supercritical fluids as solvent replacements, disposed the inventor to create a novel form of hydrogen packaging by dissolution in a specially blended solvent maintained at specified temperature and pressure conditions at which intermolecular attractions and related critical region phenomena permit storing nine times as much dissolved hydrogen in a given volume than pure hydrogen at the same conditions. The solvent constituents selected are ethane and hexane respectively in a nine-to-one parts by weight ratio, and the solution is prepared and intended to be maintained in its packaged state at room temperature and from twenty to fifty atmospheres of pressure. The solution may be combusted in toto as a fuel, or, if desired, known means for separation of hydrogen may be applied so as to deliver pure hydrogen to a fuel cell. There are three figures of drawing and four claims.
