Title: Improvements in or relating to instruments or display devices having markings rendered fluorescent by invisible light rays
Inventor: RUSSELL VICTOR JAMES SAMUEL
IPC: G01D11/28
Filed: 1949-06-02
Abstract: 653,672. Fluorescent scales. SMITH & SONS (ENGLAND), Ltd., S. July 9, 1948, No. 18552. [Class 39 (i)] In an instrument or display device having markings which are rendered fluorescent by a source of invisible light radiations disposed in front of and to one side of the markings, one or more reflectors are so located as to direct the invisible light rays on to the front of the markings without their being obscured to view by the reflectors. In the speedometer 10 shown, the dial plate 11 is marked with graduations near its outer periphery indicating miles per hour, a pointer 12 moving over these to indicate the speed of the vehicle. Mileage recording-drums 13 carry figures which are visible through windows 14, these figures and those on the dial-plate 11 being coated with a composition which is rendered fluorescent by ultraviolet rays. Two ultra-violet lamps 17 are mounted on the instrument board 8. The dial plate is slit and bent outwardly at 18 at such an angle as to reflect the ultra-violet rays from the lamp 17 rearwardly through the window 14 on to the figures on the adjacent drum 13. The dial plate 11 is formed from metal which is polished on the back face, at least along those parts constituting the reflectors 18, while the front face is non- reflecting. The dial plate is also slit and bent outwardly to form flaps 19 making only a small angle with the dial plate so as to obscure to view the slots 20 formed beneath them but permit ultra-violet rays from the adjacent lamps 17 to pass through windows 21 in the casing 15 and through the slots 20 on to the drum 13. The flaps 19 and reflectors 18 may alternatively be formed separately and secured to the dial plate.

Title: Improvements in automatically operated brakes for vehicles
IPC: B60R21/34
Filed: 1930-06-18
Abstract: 361,337. Vehicle brakes and jacking attachments. SILVA, A. A., 96, Brownrigg Street, Kandy, Ceylon. June 18, 1930, No. 18563. [Class 103 (i).] A brake device for vehicles comprises a number of legs or drags hinged to the axles or other part, normally held in the raised position by a catch device which is adapted to be released by the driver or by collision with a buffer by a person or object on the track to lower the legs and thus raise the vehicle so that it skids along on the drags. The drags may also serve for jacking up the vehicle for repairs. Legs or drags 1, 2, 3 hinged to the front and rear axles by brackets 20 are connected together by rods 4, 5 pivoted thereto. The front drag has a hook 12 normally engaging a tongue 11 on a rotatable shaft 14 mounted in bearings on the springs of the vehicle whereby the drags are held in the raised position. A buffer 17 is secured by arms 10 to the shaft 14. Coil springs 16 on the shaft support the buffer in the raised position and hold the tongue 11 in engagement with the hook 12. A pedal 8 is connected by a rod 9 to one of the buffer arms 10. The catch 11, 12 may thus be disengaged either by operating the pedal 8 or by contact of the buffer with a person or object on the track, so as to cause the drags to fall, assisted by a spring 6, and the vehicle to be lifted and stopped thereby. The lower ends of the drags are curved as shown in Fig. 4, the radius of curvature at the rear part that first contacts with the ground being the same as that of the wheel and increasing towards the front so that the vehicle is gradually raised. The drags may be made of T-section bar and be shod with hard corrugated rubber. The drags are returned to the raised position after use by a hand-lever 7 connected to the rods 4, 5.

Title: Method of color correction for photographic multi-layer negative color film
IPC: G03C7/18
Filed: 1947-07-14
Abstract: 637,879. Colour photography. GENERAL ANILINE & FILM CORPORATION. July 14, 1947, No. 18697. Convention date, Nov. 6, 1942. Drawings to Specification. [Class 98 (ii)] Subtractively coloured multilayer negatives incorporating positive colour correction printing masks to compensate for incorrect colour absorption of cyan and/or magenta dyes are. made from a film having silver halide emulsion layers sensitive to the red, green and blue regions of the spectrum and containing cyan, magenta and yellow colour formers, respectively, with a yellow filter layer between the green and blue sensitive layers ; by exposing it to a coloured object, colour developing, re-exposing either or both of the red and green sensitive layers and then developing in a developer incapable of coupling with the colour formers but capable of producing silver and stained images of a yellow to brownish yellow colour and removing all silver. The second developer is one comprising a polyhydroxy benzene such as catechol, hydroquinone, chlorohydroquinone or pyrogallol, the oxidation products of which do not couple with the colour formers but, presumably by tanning action, precipitate in situ on the gelatin, to form " rest " images of low contrast. The red and green sensitizing dyes are of normal type and need not withstand the oxidizing action of silver bleach baths. Colour formers may be those described in Specifications 458,400 and 489,274. Yellow colloidal silver is preferred in the filter layer, or yellow filter dyestuffs may be used. Diethyl-para-phenylenediamine is preferred as colour developer. Re-exposure may be effected through the base with white light or from either side with minus blue light, or if the yellow filter has been destroyed in the colour developer, by yellow light. Alternatively, the colour developed film may be treated, in white light, in a fixing bath loaded as with propanol, butanol or amyl alcohol to remove the silver halide of the blue-sensitive layer only and simultaneously expose the remaining silver halide. A formula for the second developer specifies sodium-bisulphite, -sulphite and -carbonate, potassium bromide and byrogallol. The final treatment of the film is silver removal as by Farmers reducer and fixing in hypo. Specification 541,266 also is referred to.

Title: Improvements in or relating to the thermal treatment of aluminium base alloys
IPC: C22F1/04
Filed: 1946-06-24
Abstract: In a process of working precipitation hardening aluminium base alloys which after treatment exhibit a lamellar structure, the alloy after the initial working and prior to the final hot working operation is subjected to a solution treatment at 454 to 593 DEG C. and immediately thereafter to an intermediate thermal treatment at 343 to 399 DEG C. to precipitate a major proportion of the soluble constituents and then cooling to room temperature.  The cooling to the intermediate temperature may be at a rate not exceeding 33 DEG C. per hour and to room temperature at an uncontrolled rate.  The preferred treatment is a solution treatment at 482-510 DEG C. for 4 to 30 hours, cooling at 14 DEG C. per hour to 371 to 388 and soaking within this range for 8 to 16 hours.  This treatment may take place at any stage after the initial working and prior to the final hot working and precipitation hardening, e.g. it may follow extrusion and preceed forging.  Suitable alloys are those containing 1-12 per cent Cu, 1-14 per cent Si, 0-16 per cent Mg, 0-10 per cent Zn, the remainder being Al.
