Title: Fireproof materials and products manufactured therefrom
IPC: E04B1/94
Filed: 1954-01-20
Abstract: Combustible material is removed from rice husks leaving a residue of non-inflammable material consisting essentially of silica by drying the husks, exposing the dried husks in closed space to a uniform temperature not lower than 30 DEG C., moistering with water containing an enzyme, subjecting the moistened husks to a temperature of 40-45 DEG C. in a closed space until the temperature of the husks has increased by catalytic decomposition to a temperature not exceeding 67 DEG C, washing the solid residue and at least partially drying. The enzyme may be obtained by distilling dust obtained from rice, wheat or oats. Washing may be carried out at a temperature not lower than 20 DEG C. with lime water in a vat provided with agitators below a metal screen whereon the required product collects. The lime water treatment may be preceded by treatment with water. In some cases simple water washing is sufficient. Long-fibre plants of high silica content, e.g. equisetum palustre or equisetum arvense, may be added to the husks being treated. The product may be partially dried and mixed with solid glues or up to 20 per cent of wood chips or the like, or it may be dried, preferably with hot air until its moisture content is not more than 5-10 per cent and mixed with liquid or semi-liquid binders or glues, e.g. phenolic resins. The treated husks may be formed into sheets.

Title: Method and apparatus for shipping mineral solids and other particulate matter
IPC: E02F3/90
Filed: 1969-07-30
Abstract: In a method of shipping particulate mineral solids they are pulped with water to form a slurry which is pumped into the hold of a ship and allowed to settle. This settling may be promoted by sonic vibrations. The supernatant water is decanted, leaving the mass of settled solids as a non-shifting cargo, and the cargo transported to its destination where the solids are repulped with water to form a slurry which is pumped out of the ship. Fig. 3 shows suitable apparatus for carrying out the above method and this comprises a ship 30 with a number of watertight holds such as 31. A slurry distribution manifold 39 with valving 41 routes the slurry to or from the various holds via inlet discharge pipe 42. A water pump 44 and discharge line 42 remove the supernatant water. The ship 30 may be served by an offshore pumping station with a submerged pipeline, Fig. 2 (not shown). At the destination the solids are repulped with water from high-pressure jets 62 at a plurality of sumps 50 with sonic resonator drives 56 promoting the action. The slurry is discharged through pipe 42 by pumps 55. Additional high-pressure water monitors 63 on deck may assist the discharge. Fig. 5 shows an arrangement in which the entire operation is carried out from above. A pump 70 is installed at the lower end 71 of an hydraulically movable articulated boom 72 together with a resonator drive 74 and water jet nozzles 75.

Patent ES-406736-A1 (ES)
Title: Manufacture of patterned glass
IPC: C03B18/02
Filed: 1972-09-16
Abstract: Patterned float glass is manufactured by locating in contact with the float ribbon, while it is hot, a shaped molten body of a material for modifying the glass surface. The configuration of the molten body is progenitive of a pattern to be introduced into the glass and ionic migration is engendered electrically between the molten body and the glass in a sequence of defined time periods to produce a pattern of modified glass in the ribbon surface. The pattern is formed by switching electrical current supplied to the molten body in sequence while the glass is moving relative to the molten body. The supply may be direct current, alternating current or rectified alternating current, and, in all cases, the switching is an enforced switching of the supply current between different current levels, and is not, for example, merely the result of the alternating current itself when such forms the current supply. In addition, this method of manufacture may be applied to non-float glass operations, where the glass is not supported from below by a molten bath which serves as the cathode.
