Title: Improvements in or relating to the manufacture of artificial stone surfaces
IPC: B28B19/00
Filed: 1933-08-10
Abstract: Artificial stones, or stone surfaces or stone layers, are formed with decorative surfaces by applying a solutionof one or more crystalline substances, e.g. Epsom salts to a support or mould, crystallizing the solution in situ, and then filling the mould or covering the surface with a binding agent, e.g. cement, allowing to set and removing the mass with the crystalline surface adhering thereto.  The crystalline surface may be coloured by spraying it tangentially with colouring matter, by including a colouring material in the original solution of the crystalline substance, or by spreading, e.g. a bronze lacquer on the surface and rubbing in the depressions.  The artificial stone mass may be of a different colour to the crystals.  Small bright particles of, e.g. silicon carbide, nonrusting steel or bronze, may be sprinkled on the crystal surface before the addition of the cement and so glitter through the crystal.  Japan wax may be applied to the crystal surface as a preservative.  Preferred cements are aluminous cement, ciment fondu, or magnesite.

Abstract: 189,501. Liebmann, A. G. Aug. 23, 1921. Combined fluid-actuated and mechanical gears; slide valves, flat.-A shovelling machine comprising a shovel pivoted to a shoot is mounted .on a truck driven by a twin cylinder reversing engine provided with slide valves 26, Figs. 32 and 33, each with a central aperture 27 open to an exhaust port 21. The shovel is oscillated by a motor 177, of which the piston 184 is reciprocated by fluid admitted through an inlet 188 passing through a port 190 to raise a valve 193 partially, fluid then passing around the flange 195 of the valve to move the piston 184. Towards the end of the stroke the piston passes an exhaust port 186, completes the movement of the valve 193 by contact therewith of a tappet 205, and compresses fluid in the upper cylinder end, this fluid then effecting the return stroke, during which exhaust occurs first through port 186, and through port 190 around the lower end of the valve 190, while after the valve has been moved downward by cushioning, exhaust is completed through ports 196, 192.

Abstract: 1,241,018. Cathode-ray tubes. RANK ORGANISATION Ltd. 7 May, 1969 [13 May, 1968], No. 22558/68. Heading H1D. In a flat cathode-ray tube wherein an electron beam from a gun 3 is projected parallel to the screen 2 and deflected along the screen by means 12, the angle of attack of the beam on the screen is increased by the provision of an electrostatic field which increases with increasing distance from the means 12. The field may be provided by parallel strips 16 which are connected inside or outside the tube by equal resistances R, the spacing between the strips varying progressively as shown. Alternatively, Fig. 5 (not shown), the strips 16 may be equally spaced but connected by resistances which increase progressively. The strips may be constituted by conductive strips formed on an insulating substrate by printed circuit technique. One end of the resistance chain is connected to beam potential and the other end to near cathode potential; preferably a grid 19 at beam potential is provided near the screen so that an accelerating potential may be connected between the grid 19 and a metal backing layer 20 on the screen, thereby increasing the angle of attack still further and also improving the focus. The screen 2 may be formed on the envelope or on an adjacent transparent substrate. The electron gun 3 may be disposed at one edge of the tube (Fig. 2, not shown) or behind the screen (Fig. 1, not shown) in which case the beam is reflected through 180 degrees before entering the deflection means 12.

Title: Improvements in apparatus for classifying or separating granular materials
IPC: B03B5/62
Filed: 1927-09-01
Abstract: 301,812. France, A. Sept. 1, 1927. Inclined - trough apparatus; upward - current classifiers.-In apparatus of the kind in which the material is carried by a stream of water through a trough having an opening in the bottom for the discharge of the heavier particles, a device which is influenced by the quantity of heavier material in the trough, or a float in the carrying current, or both of these devices, control means for varying the conditions of classfication. The float 3 in the trough 2 actuates a rod 13 carrying a slotted bar 13k in which slides a block connected by a link 8k and a rod 8a, slidable in a bracket 8m, to a vertical bar 20. The bar 20, which is connected by linkage to a plate 2a on which the heavy material accumulates, is moved to the right when the float rises or the plate 2a falls. This movement causes the opening of a valve 15 controlling the flow of the carrying current, the closing of a valve 7 controlling the current supplied to the discharge pocket 4, the closing of the hopper 16 through which additional heavy material is supplied to the trough, and the opening of the discharge slot 4a. Material is supplied to the hopper from the discharge pocket of an elevator 6. The relative sensitiveness of the float and plate is varied by adjusting the inclination of the slotted bar 13k to the rod 13. The plate may be grooved, perforated or provided with sides. The conditions of classfication in several troughs may be controlled by a float and plate situated in one of them.

[Class 98 (ii)] Apparatus for producing photographically parallax panoramagrams has a fixed optical system and a parallel motion linkage for imparting simultaneously a limited but continuous movement of rotation about two parallel axes of the object and a unit consisting of a light-sensitive plate and a covering lenticular screen. As shown, an electric motor 20 drives through reduction gearing a spindle 13 attached to a cross-member 11 of a parallel-motion system 11, 15, 12, 16, 18, so that the table 2 secured by a spindle 3 to the cross-member 18 and a stepped pulley wheel 21 secured by a spindle 14 to the cross-member 12 are simultaneously rotated in the same direction. The carrier 8 which contains a light-sensitive plate 7 and a lenticular screen 9 is attached to the shaft 10 of a stepped pulley wheel 22 which is belt-driven from the wheel 21. By adjusting the belt to engage different " steps " on the two pulleys, exaggerated, attenuated- or, by crossing, the belt, false-relief effects may be obtained.
