Abstract: A method of braze joining a copper member to a substrate of metal or ceramic material is disclosed according to which a diffusion barrier coating as defined is applied to the substrate alone, and a selected brazing alloy is interposed between copper member and substrate, followed by a two-step heating treatment. In the first step the assembly is heated at a temperature and for a time sufficient to melt the brazing alloy and cause a bond to form between the brazing alloy and the copper member and between the brazing alloy and the substrate. In the second step the temperature is raised and maintained in the range from about 600.degree. C. to about 950.degree. C. in a "solutionizing heat treatment" (as defined) for a time sufficient to allow the brazing alloy to form an "extended solid solution" (as defined) with copper in a controlled fashion to convert the bond to a strong joint which is resistant to thermal stress.

Abstract: Metal bonded carbon fiber-reinforced composites are disclosed in which the metal and the composite are strongly bound by (1) providing a matrix-depleted zone in the composite of sufficient depth to provide a binding site for the metal to be bonded and then (2) infiltrating the metal into the matrix-free zone to fill a substantial portion of the zone and also provide a surface layer of metal, thereby forming a strong bond between the composite and the metal. The invention also includes the metal-bound composite itself, as well as the provision of a coating over the metal for high-temperature performance or for joining to other such composites or to other substrates.

Abstract: Hair is waved or straightened by maintaining it in tightly curled or in straightened configuration in contact with an aqueous waving lotion containing sulfite, bisulfite, or hydrosulfite together with a water-soluble mercaptan, at a molar ratio of 5:1 to 1:7.5, rebuilding with an aqueous lotion at pH 7 to 12 free from cross-linking, oxidizing, or reducing agents, and subsequently applying a neutralizer solution. Minimal damage to the hair results from use of the specified molar ratio. When waving hair, an optional additional step between cross-linking and neutralizing comprises maintaining the rebuilt hair in stress-free condition in contact with the ambient atmosphere to permit the curled hair to relax to the desired extent.

Abstract: A two part depilatory composition in which the first part comprises polyvinyl alcohol and the second part comprises a cross-linking agent which consists of borax and a polyhydroxy alcohol or of Congo red, the first or second or both parts additionally containing a depilatory agent, the two parts containing such proportions of the ingredients specified that when the parts are mixed in such proportions that there is sufficient borax or Congo red to effect cross-linking of the polyvinyl alcohol, the mixed composition contains sufficient depilatory agent to effect depilation in an acceptable period and, when the second part comprises borax, sufficient polyhydroxy alcohol to moderate the rate of cross-linking.

Abstract: Novel triglyceride quaternary ammonium compounds are provided according to formula I, ##STR1## in which R is an alkyl group having 10 to 20 carbon atoms, preferably n-dodecyl or n-octadecyl, and A.sup.- is a physiologically acceptable anion, preferably chloride. These compounds are prepared by a process which essentially comprises reacting triglyceryl ricinoleate with chloroacetyl chloride to esterify the hydroxyl groups of the triglyceride and then reacting the product obtained with an alkyldimethylamine of the formula N(CH.sub.3).sub.2 R. The compounds of formula I are useful as additives to skin moisturizing compositions and hair conditioners.

Abstract: The rate and character of human hair growth including androgen-stimulated beard hair growth in intact, sexually mature males is altered by the topical application out of a dermatologically acceptable carrier of a material capable of inhibiting the action of the enzyme ornithine decarboxylase. In a preferred practice of the invention, compositions containing such materials along with anti-androgen material are employed.

Abstract: This invention relates to novel chemical compounds, methods and compositions for inhibiting the production of human perspiration, especially axillary perspiration. More particularly, the practice of the invention comprises the topical application to the axiallary area or other perspiration-producing portion of the body of an anticholinergic eucatropine ester having reduced mydriatic activity and distributed in a suitable dermatologically acceptable carrier.

Abstract: A method and apparatus for forming and packaging, within a suitable container for the dispensing thereof, an unstable product produced by intimately mixing at least first and second ingredients, the resulting unstable product remaining stable following the mixing of the ingredients for a relatively short period of time under normal ambient conditions, the method including the steps of providing streams of the ingredients, intimately mixing the ingredients in a filling head, ejecting the mixture from the filling head into a container, and sealing the container prior to the elapse of the relatively short period of time.

Abstract: This invention deals with aqueous hair treating compositions utilizing adducts of (1) low molecular weight aminopolysaccharides derived from chitosan with (2) hydrolyzed keratin protein comprising mixtures of amino acids.

Abstract: A stable antiperspirant emulsion is disclosed which contains an antiperspirant salt of aluminum and/or zirconium, volatile cyclic silicone, water, and a low pH-stable emulsifier mixture of polyethylene glycol (21) stearyl ether and a lipophilic co-emulsifier such that the HLB of the emulsifier mixture is more than 7.5 and less than 9.9.

Abstract: Inhibition of body odor is obtained by applying polyhexamethylene biguanide hydrochloride to the skin in a dermatologically acceptable carrier.

Abstract: A process is provided for the formation of metal and metal compound coatings on cutting edges by chemical vapor deposition in a deposition chamber, the improvement wherein a static electric field is established between the cutting edge and a counter electrode positioned in the deposition chamber, the field potential and gas pressure being such that glow discharge does not take place and the field potential additionally being such that a dense adherent coating is obtained.
