Abstract:
A lubrication block, with or without a cavity, or a lubrication bag, for lubricating an ID surface of a tyre and an OD surface of a plurality of pads of rotary trunnion supported equipment, such as a kiln, cooler, dryer, reactor, granulator and ball mill operating at temperatures from 100 DEG F to 500 DEG F or higher. The tyre has inner and outer faces, and the inner face of the tyre is slipped over the plurality of pads or filler bars welded to an outer shell of the rotary equipment. The lubrication block or bag is sized so as to be inserted in between the pads. The lubrication block comprises a lubricant and a solid carrier for said lubricant. The carrier is selected from the group consisting of waxes such as paraffin, polymers, copolymers such as ethylene or polyethylene glycol or mixtures thereof, and the lubricant comprises powdered carbon and a soft metal powder (e.g. copper, zinc, aluminum) or a noble metal powder (e.g. silver, copper). The lubrication bag contains a lubricant like the lubrication block and is made of a material selected from the group consisting of plastic materials such as polymers, copolymers or mixtures thereof. The carrier or the material of the bag melts and vaporizes at the temperature of the tyre, leaving very little harmful residue on the tyre except for the powdered carbon, the soft metal powders and the noble metal powders. In this way, the powdered carbon and the metal powders are capable of lubricating the ID surface of the tyre uniformly, without having to use messy hoses, pumps, or kegs containing the lubricant, in order to apply the lubricant to the ID surface of the tyre.
Abstract:
The invention generally relates to gelled oil compositions which employ aluminum soap complexes as gelling agents. The aluminum soap complexes are preferably formed in situ by reaction of the tri-aluminum-tri-isopropoxide with stearic acid and benzoic acid. The gelled oils comprise an oil component, preferably mineral oil, a bleed inhibitor of polybutene, and optional amounts of antioxidant and pour point depressant. The gelled oil compositions are stable throughout the temperature range of use, cohesive, soft and resistant to flow under gravity, and have improved lubricating properties while avoiding abrasiveness. The gelled oils are particularly suited for use as buffer tube gels and as filling compounds for waveguides.
Abstract:
The invention concerns the use of mixed hydroxydes of bivalent and trivalent metals with a three-dimensional space-lattice structure of the garnet type to control the thixotropic thickening of aqueous preparations, using swellable clays and/or other swellable layer-silicate compounds of natural and/or synthetic origin as visosity-increasing agents. The preferred garnet-type mixed hydroxydes are catoites of the basic structure Ca3Al2(OH)12 a minor proportion of whose OH units can be exchanged for acid groups, in particular silicate groups.
