Title: Improvements in electric arc lamps and light condensers
IPC: H05B31/00
Filed: 1924-02-23
Abstract: 231,637. Taylor, H. D. Feb. 23, 1924. Optical-projection apparatus.-Kinematographic projection apparatus is provided with a number of curved reflectors for forming an image of the crater of an elbowed arc in the centre of the projection lens, such image being free from astigmatism and spherical aberration. Light rays from the crater P of the electric arc are reflected from the concave mirror M1, having its centre of curvature at the point F1, the converging cone of light focusing into stigmatic focal lines p1, s1. Before reaching these foci the beam is intercepted by a convex mirror M2 situated at an angle, of 30‹ with the central incident ray C1, C2, so that this ray is reflected in the direction C2, C3, and the lines p1, s1 reflected to p2, s2 with a reduction of astigmatism and coma. The rays from the second mirror M2 are received by a third mirror M3, which is concave with its centre of curvature at the point F, and arranged at an angle to the central incident ray C2, C3 in a plane perpendicular to that of Fig. 4, and the rays are reflected to the point B3 where an anastigmatic image is formed. To adapt this system of mirrors to projection lenses of differing focal lengths the distance of the mirror M<3> from the convex mirror M2 is varied, together with a slight alteration of its angle of inclination to the principal ray. Numerical data are given of the curvatures of the mirrors and the angles to which they are set in regard to one another. The carbons N, P, Fig. 6 may be fed by hand or by an electric motor and are provided with friction gearing arranged to permit a variable velocity ratio between the two carbons. The positive carbon P is fixed in a sleeve 1 carrying a flat disc 3 having a toothed wheel 4 on its periphery. A similar disc 3<a> is carried on the mounting of the. carbon N, and the two discs are connected by friction wheels 18 carried by an inclined shaft 20 mounted in a bearing and adapted to be turned about the pivot 22 to alter the velocity ratio of the feeds of the two carbons. The wheels 18 are held in contact with the discs 3, 3<a> by springs. Handwheels 13 are provided for feeding the carbons or the wheel 4 may be motor-driven. Alternatively a sliding toothed wheel on one carbon actuates a friction wheel movable at right angles to the axis of the second carbon and in contact with a friction wheel on the second carbon. Specifications 210,705 and 230,152 are referred to.

Title: Improvements in or relating to the fugitive tinting of textile materials
Filed: 1950-02-24
Abstract: Textile materials, particularly artificial filaments and yarns, are marked for identification purposes by application thereto of a tinting fluid consisting of a fugitive dye in an aqueous liquid containing isobutyl alcohol and a dialkyl ester of sodium sulpho-succinic acid.  The tinting fluid may contain 1.0-5.0 per cent of isobutyl alcohol by weight, and 0.2-1.0 per cent of a dialkyl ester of sodium sulphosuccinic acid.  The dioctyl, diamyl, dihexyl, and dibutyl esters may be used.  The isobutyl alcohol inhibits bacterial deterioration of the tinting liquid and its presence does not decrease the fugitive nature of the dye.  Textile material of natural or regenerated cellulose, silk, wool, nylon, or cellulose acetate or other cellulose ester or ether may be treated.  The dye is selected so as to be fugitive for the material to be treated.  In the case of cellulose acetate material, the dye may be an acid dye such as is used for dyeing wool, e.g. Acid Fast Violet B.G.ALSO:Textile materials are marked for identification purposes by applying thereto a tinting fluid consisting of a fugitive dye in an aqueous liquid containing isobutyl alcohol and a dialkyl ester of sodium sulpho-succinic acid.

Title: Bottle Washing Machines.
Inventor: THORNTON ALFRED AUGUSTUS
IPC: B08B9/42
Filed: 1916-04-05
Abstract: 101,253. Thornton, A. A., (Barry-Wehmiller Machinery Co.). April 5, 1916. Bottles, washing.-In bottle-washing machines, in which the bottles are placed in carriers mounted on endless chains and carried through a tank, the chains are enclosed so that the washing-water cannot come into contact with them. The chains 6, Fig. II., run on Z-bars G secured externally to the walls of the tank, which extend beyond the lower flanges of the Z-bars to form splash guards 13. Inner splash guards are formed by the depending sides of the fixed hood 15. The carriers 18 are secured to the chains by bent brackets 19 passing between the two splash guards. As the chains are moved intermittently across the top of the tank, each bottle is rinsed five times, thrice with tank water and twice with clean water. For this purpose, the tank is divided into two compartments A, B containing two and three rinsing- nozzles 21 respectively. The nozzles in the compartment B are supplied by a pump 55, Fig. I., which draws water from the compartment A through the pipe 54, while the nozzles in the compartment A are supplied with clean water from an external source. The nozzles are raised to enter the bottles and lowered again alternately on the guides 41 by oscillating counterweighted arms about the shafts 58, 58'. Cranks 61, Fig. I., on these shafts are coupled by a rod 62, which is reciprocated by a link 63 and crank 64 on a shaft geared to the main driving-shaft 24. To obtain the intermittent movement of the chains, the shaft 24 is geared through a spur-train to the shaft 28, which carries a continuously rotating crank 29 adapted to engage in turn each slot 30 on a wheel geared to the chain-driving sprockets This wheel is locked between successive actuations by the engagement of the concave peripheral portions 31 with the convex peripheral portion of the disk 32.
