Patent ES-8200717-A1 (ES)
Title: Process for beneficiating and stabilizing coal/oil/water fuels.
IPC: C10L1/32
Filed: 1980-11-04
Abstract: A coal slurry containing 10-60% solids by weight is optionally first coarsely ground to about 20-80 mesh. Contaminant matter released thereby, may be separated by conventional means such as froth flotation which would eliminate a large proportion of the ash which is energy consuming as well as abrasive in nature. The "clean slurry" would now have water added back and would be further ground to about 100- 300 mesh particle size and would then be cavitated by sonic energy making the particle size even smaller and freeing any remaining contaminants including iron pyrites and ash. To this, a mixture of oil is added and the coal, oil mixture is then sonified during which process spherical agglomeration of the coal and oil occurs. The agglomerate and water mixture is screened to separate out most of the water leaving behind about 10-40% water in the coal, during which process the contaminants are also discharged with the water. The spherical agglomerates are mixed with a balance of oil to about. 6 times the weight of the coal to produce a stable thixotropic fuel with excellent pipe travel characteristics due to a migration of a thin film of water to the boundry layer between the bore of the pipe and the fuel. The process including the sonification steps is also useful generally in the separation of solids by agglomeration.

Title: Rock anchoring arrangement
IPC: E21D21/00
Filed: 1981-12-17
Abstract: A rock anchoring arrangement for use especially in tunnel and mine constructions involving considerable convergences comprises an anchoring sleeve having a leading and a trailing end as considered in the direction of introduction of the anchoring arrangement into an anchoring bore in the rock formation, an anchoring rod having a trailing end portion passing through the interior of the anchoring sleeve and a leading end portion which extends beyond the leading end of the sleeve, a mounting plate arranged at the trailing end of the sleeve and engaging the rock formation around the open end of the bore, and a drawing die secured to the sleeve at the leading end. The anchoring sleeve and the anchoring rod are both retained in the bore by a body of a hardenable material, such as an adhesive, in which the sleeve and the leading end portion of the rod are embedded. The leading end portion of the rod has a smaller diameter than the trailing end portion so that a transition region exists between these portions. The drawing die has an aperture which receives the leading end portion and, when pulling force acts on the arrangement, acts on the transition region to deform the same when the magnitude of the pulling force is at a predetermined level and thus to increase the axial length of the anchoring rod. The aperture is either conical throughout, or includes alternating conical and cylindrical zones.
