  • Patent number: 5180509
    Abstract: A metal-free lubricant composition for use in threaded tube and pipe connections includes graphite and a substantially nonabrasive, friction increasing adjusting component, both dispersed in a lubricant base material in which a polyalkylene is dissolved, with the graphite being present in an amount effect to decrease a coefficient of friction of said composition, the friction increasing adjusting component being present in an amount effective to increase the coefficient of friction of the composition, and the polyalkylene being present in an amount effective to enhance formation of graphite flakes from graphite particles upon application of pressure. The lubricant composition can provide corrosion resistance as well as similar or superior lubricating properties in comparison to conventional metal-containing grease compositions.

  • Patent number: 5049289
    Abstract: A lubricant composition for use in threaded tube and pipe connections comprises from 10 to 70% by weight of pure, crystalline, graphite and from 0.1% to 10% by weight (calculated of graphite) of a special additive in the form of strongly polarizable or ionizable organic compounds like e.g. amines, amine salts, metal-amine complexes, combinations of amines with polymers, polymeric amines, ammonium compounds, alkylsulphates, organic phosphates, phosphonates and sulphonates. The balance is formed by a supporting vehicle such as an oil or grease. In this composition, the performance characteristics of the graphite have been improved by the special edditive such that it can be used for lubricating and sealing threaded tube and pipe connections under conditions of extreme pressure.

  • Patent number: 4165244
    Abstract: Soldering fluxes and methods of using same for soldering metals with solders which are molten below 400.degree. C. wherein the flux functions efficiently but with an absence or minimum of spattering of particulate solder or reaction products between the solder and flux. Soldering fluxes according to this invention can be utilized in any soldering application and by any method of soldering where it is desirable to eliminate or reduce spattering.A few examples of common soldering compositions in this category are tin, tin and antimony, tin and lead. One example of the use of such fluxes is in the soldering of tinplate can bodies whereby it is possible to minimize or substantially eliminate the contamination of the can body by the lead component of the solder when lead bearing solders are used.

  • Patent number: 3944123
    Abstract: Dimerised and trimerised unsaturated aliphatic monocarboxylic acids having at least 10 carbon atoms are advantageous in or as fluxes for soldering of tin plate. Especially valuable novel fluxes for this purpose comprise, in free acid or ammonium or amine salt form, (1) at least one compound selected from the group consisting of C.sub.7.sub.-11 aliphatic monocarboxylic acids and acid organic phosphates and (2) at least one substance selected from the group consisting of dimerised and trimerised unsaturated aliphatic monocarboxylic acids having at least 10 carbon atoms, saturated C.sub.12.sub.-36 aliphatic monocarboxylic acids and rosin.
