Title: Means for supplying combustible mixture to internal combustion engines
IPC: F02M1/00
Filed: 1923-08-17
Abstract: 203,318. Soc. Anon. des Ateliers d'Aviation L. BrÚguet. Aug. 30, 1922, [Convention date]. Spray carburettors. - Combustible mixture is supplied to an engine from apparatus consisting of two entirely distinct parts each of which comprises a carburettor with its piping and an admission valve. Each carburettor provides half the mixture feed, and that which is opened first to run the engine up to half the maximum torque, contains a slow-speed device. Super-compression at high altitudes may be obtained by adjusting the first carburettor to produce at full opening the maximum compression on the ground, the second carburettor being brought into action as the aircraft rises. Reference has been made by the Comptroller to Specifications 110,542, 125,408, 127,850, 145,648, 149,945, 157,234, 191,400, and 195,966.

Abstract: 1515125 Projection printing AGFAGEVAERT AG 19 May 1975 [17 May 1974] 21169/75 Heading G2A A copier comprising a transparent platen for supporting an original has a pivotal mirror enabling alternative projection on to imaging material from each side of the original. The imaging material may be stationary or moving during exposure, flash illumination being used in the latter case; and may be direct or transfer electro-photographic material, e.g. an endless belt. A single stationary objective may be situated between the pivoting mirror and the imaging material, a single pivoting objective may be situated between the original and the pivoting mirror, or a stationary objective may be situated in each projection system between the original and the pivoting mirror. As shown, the change-over from one projection system to the other is effected by means of mirror 26 which pivots from one light-reflecting position to another. In another form (Fig. 2), the change-over is effected by a mirror (31) which pivots from a lightreflecting position to a light-passing position, light from the unrequired projection system being blocked in each position.

Abstract: 684,920. Clocks; displaying. SMITH & SONS (ENGLAND), Ltd. S. Aug. 28, 1951 [Aug. 28, 1950], No. 21181/50. Classes 3 (i) and 139 In a clock mechanism a pivotal lever of the escapement has a pin and slot or other lost motion connection with one arm of a bell crank lever, the other arm of which constitutes a part of a pendulum which has a swinging motion about an axis which is adjustable relatively to a framework of the mechanism and is normal to that of the normal pivoted displacement of the escapement lever. The framework comprises two plates 10 and 11, Figs. 1 and 3, spaced by pillars 12 and supported on columns 13 mounted on a base 1.4. The mainspring 16, Fig. 3, drives the minute hand 20 through the wheel 17 and the pinion 18a. The hour hand 26 is driven through the motion work 22, 23, 24, 25. The escapement lever 35 co-operates with the escape wheel 32, Fig. 4, and is slotted at one end to embrace the end 38 of a wire loop 39, Fig. 2. The wire loop 39 is provided with two hooks 40, 41, which hook on to a bar 42 pivotally mounted on a bracket 45. A second wire loop 47 is attached to the loop 39 and supports a doll-like object 48. The loops 39, 47 and the object 48 form the pendulum which oscillates in a direction normal to the dial. If the base of the clock is not on the level the bar 42 is displaced about its pivot until an even " beat is obtained. The casing 15, Fig. 1, is of glass.

Electrolysis of solutions of alkali-metal chlorides using a graphite anode and a mercury cathode is carried out with the addition of one or more silicon compounds consisting of colloidal silicic acid or of substances converted into colloidal silicic acid under the conditions of the electrolysis. The silicon compounds may be added to the electrolyte, or the anode may be impregnated with these compounds. Examples of compounds which produce colloidal silicic acid are dissolved or reactive silicates such as waterglass. Barium silicate may be used when the electrolyte is contaminated with alkali-metal sulphate which it is desired to precipitate as barium sulphate. The silicon compounds may be added to the electrolyte in an amount of 0.0001 to 0.05 per cent, calculated as silicon dioxide.
