Abstract: 573,855. Decorating fibrous surfaces. FRIEBERG, H. and FREIBERG, S. Dec. 16, 1943, No. 21150. [Class 93] Decorating a fibrous surface with beads of synthetic resin by applying droplets of a hardenable synthetic resin to the surface of the material to be decorated and applying to portions of the surfaces of the droplets while still in the liquid or tacky form solid of such a fine degree of division that it forms on the droplets a'coating which appears substantially continuous, the solid being blown on at a small angle to the'surface supporting the said droplets and in the same general direction and thereafter causing or allowing the droplets to set and harden. The finely-divided solid may be applied in a gentle current of air, e.g., by means of a rubber blow ball. Metallic dust such as bronze (which may be dyed) is specified. In an example, a pigmented urea formaldehyde resin syrup mixed with a hardener is deposited in droplets on a fabric and, while the droplets are still tacky, finely divided metal powder is blown from a rubber blow ball at a small angle to the surface on to the droplets. The fabric is then heated until hardened and excess of powder removed by light brushing. Specifications 247,282, 277,091, [both in Class 93], and 565,711 are referred to.

Abstract: 715,047. Diffusing light. HOLOPHANE, Ltd. (Holophane Co., Inc.). Sept. 17, 1951, No. 21751/51. Class 75 (2) Means for diffusely transmitting light rays comprises a light transmitting member having a flute on one surface with its longitudinal centre line lying along the intersection with the surface of a plane normal to the surface, the flute being of alternately maximum and minimum width to intercept varying widths of light beam, having a longitudinal profile made up of a series of curves and being generated by a curve a point of which moves in the said plane; or the means comprises a light transmitting member having one surface provided with contiguous rows of contiguous lenticulations each curved in two sections at right angles, any one row of lenticulations being generated by the movement of a curve along the row and the lenticulations in one row being staggered with respect to those in adjacent rows. The mould for producing the fluted or lenticulated surface is machined with a cutter 20 having a curvature corresponding to the transverse curvature of the flute. The cutter is moved along a cusped path determined by a cam surface 21, and forms a flute constituted by a row of depressions the mid point of the cutter profile moving in the plane normal to the surface through the longitudinal centre line of the flute. The cam'surface 21 is moved both laterally and longitudinally between successive cutting operations and the resulting depressions assume the shapes of symmetric or asymmetric contiguous diamonds or hexagons, the diamonds of each flute being disposed point to point. The cam surface 21 may provide a path of ogee profile instead of the cusped path shown and in this case the lines separating adjacent flutes are ogee, Fig. 14, and the longitudinal profile of each flute is ogee. The conical refractor, Fig. 19, has flutes 40 of ogee from similar to the flutes shown in Fig. 14 separated by flutes 41 having longitudinal profiles substantially parallel to the surface of the refractor and generated by a curve moving in their longitudinal directions. The refractor bowl shown in Fig. 24, has downwardly converging side walls provided with nested convex diamond-shaped lenticulations in three zones defined by the lines Y-Y and Z-Z. The mould is formed by moving the cutter in vertical radial planes, a different cutter being used for each zone. The lateral spread produced by the diamonds in all three zones is from 10 to 25 degrees and the vertical spread produced by the upper zone is between 5 and 10 degrees and by the middle and lower zones between 10 and 20 degrees. The lenticulations may be made by machining the light transmitter instead of machining a mould and in this case the lenticulations are concave.
