Abstract: A device for mixing methyl methacrylate monomer and methyl methacrylate polymer to form bone cement in a hospital operating room includes a bowl-shaped container, a replaceable resilient plastic bowl-shaped liner which fits in the bowl-shaped container, a fluid passageway formed between the liner and container and a deflector cap which covers the space between the upper end of the liner and the upper end of the container. Exhaust openings in the side wall of the liner place the interior of the liner in fluid flow communication with the fluid passageway. The methyl methacrylate monomer and polymer are mixed in the bowl-shaped liner.

Abstract: Preparation of APAP tablet containing fumed silica by (a) forming a solution of APAP in an organic solvent, (b) suspending or dispersing in said solution powdered fumed silica, (c) drying said suspension to form a APAP-fumed silica mix, and (d) pressing a mixture containing said APAP-fumed silica mix into a tablet.

Abstract: The embodiment of the invention disclosed herein is directed to a joint prosthesis for total knee replacement. The joint prosthesis includes a first prosthetic member including a stem member adapted for insertion into a first skeleton element. A second prosthetic member includes a stem for insertion into a second skeleton element which is disposed adjacent to first skeleton element. The joint prosthesis is provided with a removable plateau member which forms a slide or rubbing surface for the prosthetic members. The removable plateau can be replaced when worn. Retaining screws are provided on opposite sides of the first prosthetic member to retain the ball within the socket therein.

Abstract: There is disclosed a storage stable solution comprising a solution of erythromycin, propylene glycol, ethyl alcohol, and an ethoxylated ether of lauryl alcohol. The solution possesses excellent stability at both room temperature and at elevated temperatures for prolonged periods of time.

Abstract: Shampoo compositions capable of conditioning hair containing relatively high quantities of beer solids as hair conditioning agents.

Abstract: A circular tubular cap and dummy cosmetic stick assembly in which the cap is transparent near the top and opaque near the bottom. The dummy cosmetic stick (e.g. lipstick) is maintained in place in the cap near its top by means of upwardly extending flexible tabs which form part of a tray that forms the base of the dummy cosmetic stick.

Abstract: A combination of corrosion inhibitors which act synergistically to prevent corrosion in compositions containing a chlorinated hydrocarbon and a substantially large amount of water.

Abstract: A bottle packing system including an oscillating grid for transferring bottle groups from a grouping station to a carton-filling station, the grid including tensioned resilient means for engaging and retaining bottles in the grid during its oscillation, and a positive-ejection member rockable into the grid for ejecting the bottles from the grid at the carton-filling station.

Abstract: Hair dyeing compositions are disclosed which contain an N-substituted o-phenylenediamine, the N-substituent being an alkyl, alkoxyalkyl, hydroxyalkyl, alkylaminoalkyl, dialkylaminoalkyl, phenyl or substituted phenyl. These give reddish shades by purely oxidative means, and the shades are fast to wet treatments and are long-wearing. Also disclosed are methods of dyeing hair with these compositions, as well as certain novel compounds suitable for the purpose, e.g., N-(alkoxyalkyl)-o-phenylenediamines.

Abstract: Terpenes and their derivatives provide improved stability to aqueous solutions containing hydrogen peroxide as well as to aerosol co-dispensing hair coloring systems containing oxidation dye compositions.

Abstract: Oxidative hair dye composition containing as "para component" compounds of the formula: ##SPC1##Or their acid addition salts, in which:R.sub.1 is alkyl or hydroxyalkyl;R.sub.2 is hydrogen or hydroxyalkyl;R.sub.3 is hydrogen, alkyl, alkoxy or halogen; andR.sub.4 occupies any one of the remaining positions on the benzene radical and is hydrogen, alkyl, alkoxy or halogen; providing that R.sub.2 is hydrogen when R.sub.3 is alkyl, alkoxy or halogen and providing that at least two of R.sub.1, R.sub.2, R.sub.3 or R.sub.4 are other than hydrogen.

Abstract: A granular drain cleaning composition which remains physically separated in two parts until utilization in the presence of water, useful for freeing a clogged drain of grease, hair, oils, and other debris is disclosed. One part contains an alkali metal hydroxide which is either sodium hydroxide or potassium hydroxide, the other part contains one or more ingredients that are chemically incompatible in the dry state with the alkali metal hydroxide, the ingredients including an acidic agent which is sodium bisulfate or citric acid, and an oxidizing agent. The oxidizing agent is preferably sodium carbonate peroxide, sodium perborate monohydrate or monopotassium peroxymonosulfate. Optionally, an anionic or nonionic surfactant foaming agent can be included.

Abstract: Drain cleaning compositions, especially effective in dissolving soap curd, are provided which comprise in aqueous solution a potassium salt of nitrilotriacetic acid, N-2-hydroxyethylimino diacetic acid, an alkylene polyamine polycarboxylic acid, or mixtures thereof, and potassium hydroxide, wherein the compositions are substantially free of other alkali metal ions and the alkylene polyamine polycarboxylic acid has the formula(HOOCCH.sub.2).sub.2 N[(CH.sub.2).sub.x NCH.sub.2 COOH].sub.y CH.sub.2 COOHwhere x and y may each independently be from 1 to 4.

Abstract: Prepares 2-nitro-4-amino-N-phenylaniline by reacting 4-fluoro-3-nitroaniline at a temperature of at least about 140.degree.C and in a large molar excess of aniline e.g. molar ratio of aniline to 4-fluoro-3-nitroaniline being at least about 5:1.
