Abstract: In a method of preparing coal in particulate form for charging coke ovens, the particulate coal is initially treated with a binding agent selected from carbo-pitch, residues of coal oil refining and oil refining residues; particulate coal so treated is mixed with 0.1 to 0.3% of light oil and subsequently agglomerated before feeding into coke ovens. Non-self-fluxing coal may be treated by this method and mixed with granulate self-fluxing coal to form a coke oven charge.

Abstract: A lubricating oil composition having particularly improved friction reducing properties which comprises an ester of a polycarboxylic acid with a glycol or glycercol and a selected metal dithiocarbamate and contains a relatively low level of phosphorus.

Abstract: The spreadability of marine diesel cylinder oils is improved by the incorporation therein of a spreadability improving amount of a polyalkoxylated phenoxy compound having the formula: ##STR1## wherein R is an aliphatic hydrocarbyl group having from 5 to 70 carbon atoms and n ranges from 14 to 30.

Abstract: A process for the production of an aqueous lubricant composition free of oil including water and at least one metallic carboxylate, wherein the anionic is at least one saturated linear organic radical containing at least 12 carbon atoms and the cationic is at least one bivalent or trivalent metal having an electro-chemical oxidation-reduction potential greater than -0.7 volts. The process includes mixing of two mother solutions. The first mother solution is an aqueous solution of at least one alkali metal carboxylate soluble in water wherein the anionic is at least one saturated linear organic radical with at least 12 carbon atoms. The second mother solution is an aqueous solution of at least one metallic salt whereof the anionic is selected from the group consisting of hydroxide, chloride, sulphate, nitrate or phosphate ions and whereof the cationic is at least one bivalent or trivalent metal having an electro-chemical oxidation reduction potential greater than -0.70 volts.

Abstract: There are applied gold containing preparations as intermediate layers for facing fired on alloys with ceramic compositions in the dental art. These gold preparations should improve the adhesiveness, form a structured surface and make possible a saving in the consumption of gold. This is accomplished with preparations that contain 60 to 95% gold powder, at least 50% of which are platelet shaped particles, 5-40% of a binder and in a given case up to 20 of a powder as an adhesive which is made of metals and/or non-metals.
