Title: Improvements in furnace grates
IPC: F23H9/00
Filed: 1920-09-20
Abstract: 164,272. Ramsey, A. R. J., (Cokal Stoker Corporation). Sept. 20, 1920. Fire-bars and grates.-A grate constructed of fire-bars rocked about their longitudinal axes is adapted to move the fuel progressively from front to rear of the furnace, and to maintain a uniform air space between the bars during tilting. The bars 15, 16, which pivot about end trunnions, have intermeshing fingers and downwardly extending arms 18, connected pivotally to a shaker rod 19. The bars have perforated faces 25, Fig. 9, and curved, depending aprons 26, 27, eccentric to the trunnions 17. During tilting of the bars the aprons follow closely the adjacent faces 25, forming grooves into which the fuel falls, and from which it is ejected on to the next bar when the bars are returned to their normal positions. A fixed or tilting end section 42 is provided beyond the rearmost bar for the discharge of ash &c. The bar trunnions are carried in structures, Figs. 4 and 5, comprising interlocking side frames 30 and pierced blocks 33 retained in position by side bars having lugs engaging the masonry of the adjacent walls.

The balls may be connected by a spindle 8. In modifications, the races are curved and may have their common centre on the joint centre. The hollow cups 6 may be part-cylindrical axial grooves to allow axial movement of the joint. In another modification the pivot is omitted and the central ball is retained in deeper central cups, screw means being provided to prevent loss of the outer balls by excess angular movement.

Abstract: 1,128,995. Bags with securing devices. FLEXIGRIP Ltd. 17 June, 1966, No. 27140/66. Heading B8K. [Also in Divisions B5 and E2] A thermoplastics bag has opposite sides 17, 18 each formed by extrusion of a flexible thermoplastics sheet simultaneously with a flexible thermoplastics bead 33a, 33b integral with the sheet, the pair of beads extending along the respective sides adjacent the bag opening so as to be parallel to one another and having permanently magnetizable material embedded along their lengths and at least one being permanently magnetized so that the beads attract one another and thus constitute a fastener for the bag. The opposite sides of the bag can be formed from separate sheets which are subsequently joined together, alternatively the opposite sides are integral with one another in which case they are formed by the extrusion of a single flexible thermoplastic sheet simultaneously with the pair of flexible thermoplastic beads integral with the sheet, the sheet then being joined along its edges so as to form the bag. The permanently magnetizable material can be a wire or it can be in the form of discrete particles. When a single sheet is used it can be extruded so as to be tubular in cross-section, the beads being extruded at the same time, after which the sheet is slit longitudinally between the beads. A die is shown in Fig. 2, having a cylindrical bore 51 through which molten thermoplastic material 54 is forced, a mandrel 56 being situated concentrically within the bore 51 and the die having a passage 61 in its wall through which molten thermoplastic material containing magnetizable particles is forced into the die. A modification is described in which wire is forced into the die instead of the material containing the particles. When both beads are magnetized they are magnetized so that the facing parts of the beads have opposite magnetic polarities.

Title: A process for treating masonry
IPC: C04B41/70
Filed: 1959-08-10
Abstract: Masonry surfaces are treated by applying thereto a solution or emulsion containing from 0,01% to 1% by weight of an air-drying organosilicon compound which is allowed to dry, and applying a Portland cement composition to the treated surface and allowing it to set.  The organosilicon compound is a hydrolyzable silane, a partial hydrolysate thereof, an organopolysiloxane, or an alkali metal salts of these.  In the organosiloxanes a major portion of the polymer linkages are Si-O-Si linkages and any remaining linkages are of the type Si-Sc or Si-R1-Si, R1 being a divalent hydrocarbon radical, or both.  The remaining valencies of the silicon atoms are satisfied by monovalent hydrocarbon radicals, which may be alkyl, alkenyl, cycloaliphatic, cyclo-alkenyl, aryl, aralkyl or alkaryl.  The organosilicon compound may be applied as a solution, e.g. in xylene, toluene, mineral spirits or chlorinated hydrocarbons, or as emulsion, and the alkali metal salts as aqueous solutions.  Suitable Portland cement compositions contain at least 48% by weight (dry basis) of Portland cement, and may also contain lime, pigments, (which may be coated with hydrolyzable silanes), binders such as sodium silicate, inert fillers, wetting agents and materials such as bentonite, calcium stearate, aluminium silicate and calcium chloride, and a portion of the primer dispersion.  They may be applied as a grant, a poured concrete, a stucco or a paint to such masonry as mortar, concrete, cement-base paint coatings, asbestos-cement, sandstone, limestone, brick, cinder block, "Brickcrete" (Registered Trade Mark), and tile, after these have been coated with the organo-silicon compound.  Examples show the bond strength of a Portland cement mix, of 3 parts masons sand to 1 part Portland cement, to bricks and other materials pretreated with various organosilicon compounds. Specifications 714,461, 749,799, 749,938 and 860,522 are referred to.ALSO:In providing masonry surfaces with a portland cement coating, (see Group III), the surfaces are pretreated with a solution or emulsion of an air-drying organosilicon compoind.
