Patent GB-1023764-A (GB)
Title: An improved method of glazing and decorating ceramic tiles and similar articles
Inventor: COLLINS WILLIAM GODFREY
IPC: C03C8/04
Filed: 1964-01-30
Abstract: Ceramic tiles and like articles are decorated by applying a design in a glaze containing a silicone and then, before the design glaze dries, applying a water-suspended background glaze so that the background glaze is repelled by the design glaze and the two remain separate during fixing.  The design glaze may comprise a lead silicate or boro-silicate, an alkali metal borosilicate, or an alkali metal-lime-boro-silicate, and is mixed with the silicone and a vegetable or mineral oil, e.g. pine oil and an alkyd resin or a light lubricating oil.  The silicone is present in an amount approximately 5% of the oil and the oil/silicone mixture is mixed with 1.5 to 3 times its weight of the glaze.  The background glaze mixture is of low viscosity and high specific gravity.

Abstract: 556,915. Current and resistance measurements. SMITH & SONS (Motor Accessories), Ltd., S., and KLIPP, E. C. March 25, 1942, No. 3981. [Class 37] In a ratiometer having two coils together rotatable in a magnetic field means are provided for subjecting different effective lengths of each coil to the magnetic field as the coils move through the field. The two coils are wound parallel to one another on a former and are rotatable in the gap between pole faces and a central core, a weak control spring ensuring the return of the moving system to its zero position. As shown in Fig. 3 the core has two partcylindrical faces 37, 38 of the same diameter and coaxial with the axis of rotation of the moving system. These faces are intersected by another cylindrical face 39 having its axis at right angles to the first axis. The axial length of the airgap is thus greatest in the centre of the pole faces and diminishes on each side. In an alternative construction, Fig. 4, the core has a complete cylindrical face 40 intersected by inclined flat faces 41, 42 at the top and bottom. Parts of the edges may be chamfered to vary the scale. The upper and lower edges of the polepieces 29 may be shaped to correspond with those of the core: The radial width of the gap between the core and the polepieces may be constant along the nath of travel of the coils, as shown, or it may be made to vary by shaping the pole faces as described in Specification 546,468.

Carbon.-Electrodes are made by compressing powdered carbon in a mould, exhausting air from - the mould, allowing heated binding material to permeate the powder, and baking the resulting bodies. The moulds 5 may be introduced into a vessel 6 through a man-hole 17. After exhausting the vessel 6 by way of a pipe 7 provided with a trap 8, the binding material is admitted from a reservoir 4, previously filled from a heated mixer 1. Compressed air is then supplied to the vessel from a receptacle 14. Subsequently the superfluous binding material is forced back to the mixer 1 through a pipe 16, and the vessel 6 is heated for four hours or more. The binding material may then be readmitted and air pressure applied. After removal from the vessel 6, the electrodes &c. are baked in an oven or furnace and taken out of the mould. The reservoir 4 and vessel may be heated by electric resistances, or by steam at a pressure of 80 lb. per sq. in. The air pressure may be 125-1000 lb. or more per sq in. Heat may also be applied to the air receptacle 14. For graphite electrodes, the binder may consist of 25 per cent crude oil and 75 per cent coal tar; for coke, equal parts of pitch and tar; for coal, 25-33<1>/3 per cent crude oil and the rest of tar; for charcoal, 75 per cent tar and 25 per cent kerosene oil.
