Filed: 1933-06-19
Abstract: 409,524. Vehicle windscreens. COX, R. E., Devoncombe, Stockton Lane, York. June 19, 1933, No. 17377. [Class 103 (ii).] A windscreen for use on the front or sides of automobiles, locomotives, aeroplanes, &c. has a direct-vision or observation gap D through which air-currents are prevented from penetrating by means of a series of curved deflecting- vanes 1, 2, 3 and 4, 5 arranged respectively below and above the gap so as to direct a strong current of air upwardly across it, an area of low pressure being formed behind the foremost upper vane 4 which draws the air up between the vane 4 and the curved hood 5. The vanes may be fixed directly or through distance-pieces &c. to side-screens X, Y and in the case of windscreens of greater width that 4¢ inches, one or more additional divided transparent screens R, S, Fig. 5, may be fixed parallel to and between the side-screens to prevent crosscurrents of air disturbing the upwardly-moving air. Air from a pump, reservoir, &c. may be forced upwards between the vane 1 and an auxiliary vane between the vane 1 and the vehicle to increase the force of the upward flow through the other vanes. When a screen of narrow width is used on the side of a vehicle a lower horizontally-projecting vane 6, Fig. 2, prevents air from being blown upwards against the face of the observer, while the hood 5 protects the top of the observer's head.

Title: Process for proofing fibrous materials against pestiferous organisms
Filed: 1958-06-05
Abstract: Fibrous material, e.g. a textile, is treated to render it resistant to pestiferous organisms by contacting it with an aqueous metastable dispersion containing a tetravalent organo-tin compound having at least one organic radical linked to the tin atom through a carbon atom and a surface-active agent, breaking the dispersion in contact with the material by application of heat to deposit organo-tin compound on the material, and removing at least part of the aqueous phase in the liquid state before drying the treated material.  The Specification includes lists of pestiferous organisms, fibrous materials, surface-active agents and organo-tin compounds.  The latter includes compounds of the following types: SnR4, SnR3X, SnR2X2, SnRX3, SnR3OH, (SnR3)2O and SnR2O, where R is an organic radical linked through a carbon atom and X is a halogen or the radical of an organic or inorganic acid, or an organic radical linked through oxygen or nitrogen.  The fibrous material may be immersed in the dispersion, which is heated to break it while the fibrous material is still immersed. Alternatively, the material may be removed from the dispersion before heating, heated to break the dispersion, and passed through pressure rolls to remove the major amount of the water before drying.  In a modification, after the fibrous material has been treated with the dispersion, the dispersion broken, and at least part of the aqueous phase removed, it is treated with a dilute acid to convert the tin compound, e.g. tributyl tin oxide, into a solid tetravalent organic tin compound before drying. The dispersion may also include a resinous adhesive, e.g. polystyrene, a polyvinyl ester or a vinylidene copolymer, a water-softening agent, an optical bleach, a germicide or fungicide other than an organo-tin compound, or a dye or pigment.
