Abstract: 380,425. Making plate glass. BRANCART, Y., Verreries de Fauquez, RonquiÞres, Belgium. July 20,1932, No. 20541. [Class 56.] Relates to the production of plate glass free from surface undulations, by the method described in Specification 336,921, [Class 56, Glass], in which a roller is rotated at a higher circumferential speed than if it were rolling over the glass, and the plastic sheet is impressed with slight depressions which disappear as the glass cools. According to the present invention, the impressing roller is so supported above the casting table that the table does not make contact with the roller itself or with its trunnions. In the construction shown, the roughsurfaced impressing-roller 2 has its trunnions 2<1> journalled in bearings 10 which are supported by means of wheels 11 on the edges of the casting table 1. The roller is rotated by a cable 4 secured at its ends 12 to the table 1 and wound around a pulley keyed to the roller. The table moves along a roller track and its movement rotates the roller, but the table may be kept stationary if desired and the roller moved over its surface.

Title: Improvements in or relating to methods of making basic refractories
Inventor: WOODHOUSE DENNIS
Filed: 1962-05-29
Abstract: A refractory composition comprises dead burned magnesia in admixture with a small proportion of calcium oxide or calcium oxide precursor (e.g. 0.1 to 1.0% CaO by weight of the composition), the composition having a +72 B.S. mesh fraction and a - 72 B.S. mesh fraction which includes the added calcium oxide or precursor thereof with the result that the overall CaO : SiO2 molar ratio of the -72 mesh fraction is such that the fail temperature of a refractory brick made from the composition is at least 100 DEG  C. higher than that of a refractory brick made from a composition when not containing the calcium oxide addition. The preferred overall CaO : SiO2 ratio of the -72 mesh fraction is not less than 3:1.  The intrinsic content of SiO2 and CaO taken together, in the magnesia used preferably does not exceed 5% by weight on the weight of the composition.  The magnesia used also has an MgO content of not less than 90% by weight and a total Al2O3 and Fe2O3 content of 6.5% or less, the overall CaO content of the refractory composition and the SiO2 content of the composition being such that the molar ratio CaO: SiO2 is between 2.0 and 4.2.  The composition is used to produce refractory bricks for use in furnace linings, said bricks may be metal-clad.

Title: Improvements in insulating means for high potential condenser terminals and the like
IPC: H01B17/30
Filed: 1921-08-03
Abstract: 175,595. Dubilier, W. Feb. 18, 1921, [Convention date]. Condensers.-Terminals or conductors for high tensions are insulated from the walls of an orifice by means of a plate or diaphragm of sheet mica extending from the walls to the terminal or by an insulating member consisting entirely of mica filling the opening. The capacity of such an insulator is stated to be of the order of micromicro-farads. The terminal of a condenser is mounted in a relatively large orifice 5 in an outwardly extending cover. The sheet mica diaphragm 6 is also of relatively large diameter to prevent creepage and corona effect between and on the surface of the mica laminations. It may be secured by a ring 7 and screws, the metal edges preferably being rounded. A tube of wound sheet mica extending to a considerable distance to each side of the cover may be interposed between the diaphragm and the conductor 9. Laminated mica blocks 11, the surfaces of which may be corrugated, lie on each side of the plate 6 and means such as a nut 15 on the conductor 9 preferably clamps the whole together. In a modification, the plate 6 is arranged so that its edges grip the walls of the orifice when the clamping means is tightened up. In manufacture the mica layers are first compacted under the highest possible pressure, then impregnated with a melted wax insulating composition, which may be supplemented by a vacuum and finally subjected to a minimum pressure of about one ton per square inch.
