Abstract: 1,144,239. Crystalline antimonic acid. COMMISSARIAT A L'ENERGIE ATOMIQUE. 16 Dec., 1966 [29 Dec., 1965], No. 56463/66. Heading C1A. Crystalline antimonic acid with a pyrochlore structure is obtained from an alkali metal hexahydroxoantimonate (e.g. Na Sb (OH) 6 ) by heating to about 250‹ C. The polyantimonate formed is then treated with a strong acid, e.g. nitric, sulphuric, hydrochloric or perchloric. Sodium salts are preferably used in this process. In the description sodium hexahydroxoantimonate was heated to 250‹ C. for 2 to 3 days, and the polyantimonate was treated with 2N nitric acid until all the sodium ions had been replaced; the antimonic acid then being washed with distilled water and dried at 50‹ C. This antimonic acid has good exchange capacity with respect to the alkali metal and alkaline earth ions.

Title: Electric arc welding
Inventor: DOXEY BRIAN CECIL
IPC: B23K9/073
Filed: 1967-12-19
Abstract: 1,241,959. Arc welding systems. BRITISH OXYGEN CO. 25 Nov., 1968 [19 Dec., 1967], No. 57563/67. Heading H2H. A system for A.C. arc welding comprises a main circuit for striking and energizing the arc, and an auxiliary circuit for applying a timed voltage pulse to the electrodes in order to reignite the arc after extinction. The latter includes a capacitor shunting a choke, and discharge of the capacitor may be controlled by a thyristor. In the arrangement shown in Fig. 1, the arc 12 is normally supplied through a main transformer 2 and a choke 6. When the arc extinguishes at a current zero, the voltage across the gap rises steeply and a pulse is applied through a second transformer 16 to the gate of a thyristor T. This allows a capacitor C1 to discharge through the choke 6 causing a high voltage pulse to flow and restart the arc. The capacitor C1 is charged through a transformer 4, bridge 14 and resistor R1, and is shunted by another capacitor C2 which absorbs the reverse voltage from the choke 6. This second capacitor C2 is discharged by a resistor R2. The arrangement is stated to be particularly suitable for argon-shielded arc welding of aluminium using a non-consumable electrode.

Abstract: 1487329 Roller blinds L E J RAWSON and G W BRADBURY 15 Nov 1974 [13 Dec 1973] 57703/73 Heading A4B A roller blind assembly comprises a roller 11 mounted on a shaft or shafts 12 projecting from the roller ends, a spring mechanically interconnecting the roller and the shaft(s), support brackets at the roller ends, and co-operating cam and detent means mounted on the or a shaft and one of the brackets 14 to permit rotation of the shaft relative to the bracket 14 in one direction to pre-tension the spring and to prevent relative rotation in the opposite direction. As shown the cam comprises a toothed disc 16 secured to the shaft 12 and the detent comprises a tooth 19 or other projection carried by an elliptical shoulder 18 on the bracket 14. The shaft 12 has a hexagonal part 20 disposed between the cam disc 16 and the roller 11. To pre-tension the spring a spanner is engaged with the hexagonal part 20 and rotated in the direction A causing a lateral displacement of the cam disc 16 as its teeth 17 ride over the fixed tooth 19. When the spanner is removed after obtaining the desired pre-tensioning the spring reaction urges the cam disc 16 to the position of Fig. 2 to prevent reverse rotation. The assembly may include a check-action mechanism. Additional leaf or coil springs may bias the cam disc 16 into engagement with the detent tooth 19. In an alternative arrangement the cam disc could be carried by the bracket and the detent tooth by the shaft. The brackets may form end-walls of a box for the blind.

Abstract: 664,353. Photo mechanical printing surfaces. TILLOTSON & SON, Ltd., WILD, L., and SMITH, J. Feb. 24, 1949 [Feb. 28, 1948], No. 6310/48. Drawings to Specification. Class 98 (ii). Before the preparation of a photomechanical printing surface the surface is contoured, approximately in accordance with the density variation over the subject, by a preliminary etching after coating with a first photo-sensitive resist and exposing the resist under a diffuse negative of the subject. A printing plate of bronze, brass, zinc or copper is cleaned and coated with the first resist, preferably of bichromated gelatine containing also ammonia, Turkey red oil, and the opaque paste containing iron oxide and known under the Registered Trade Mark " Photopake ". This is exposed under the diffuse negative developed in water and etched, for example with ferric chloride. A further resist, containing bichromated fish glue or albumen, is then applied and exposed under a half-tone negative registered with the position of the diffused negative, developed in water, and fixed, for example by burning in. The plate is then etched. The two negatives are made successively with the same camera setting, the diffusion of one being produced by displacement of the half tone screen away from the plate, and being assisted by exposing at full lens aperture. With a line subject an ordinary negative is used instead of a halftone negative but a plain glass plate is inserted in place of the half tone screen, so that the same size image is produced as when using the half tone screen to diffuse the other negative. A lateral inversion is produced with a prism when photographing to enable the negatives to be printed emulsion side downwards on the printing plate. Preferably, the half-tone negative, at least, has a film base to enable it to follow the contours of the plate produced by the first etching. Alternatively, the image layer may be stripped and applied directly to the plate.
