Title: Improved methods of making flexible material having a plurality of superposed layers
IPC: B29C48/08
Filed: 1956-02-23
Abstract: 834,525. Coating webs; coated fabrics. KODAK Ltd. Feb. 23, 1956 [Feb. 23, 1955 (4)], No. 5590/56. Drawings to Specification. Class 140. A flexible film paper or other web carrying two or more superposed coatings is made by forming a thin flowable layer of a solution of each coating material, so feeding the layers as to bring them into superposed surface contact with one another in, or before reaching, a bead formed between the feeding device and the web, and producing continuous relative movement between the bead and the web. The layers are stated to retain their identity and superposed relation in the bead and to be deposited in thickness corresponding the rate of supply of the respective solutions. The layers may be formed by flowing the solutions down inclined surfaces, singly or in superposed relation, by extruding them, or by various combinations of these methods. Apparatus is described for carrying out the invention and for setting and drying the coated layers. This apparatus, which comprises generally a feeding device and a webcarrying rotating drum, form the subject of Specifications 834,526, 834,527 and 834,528. The invention is particularly applicable to multi-coated cellulose acetate and other films, and papers, for colour and other photographic purposes, the solutions used being aqueous solutions of gelatine or polyvinyl alcohol as such or containing silver halides, with or without coating aids such as saponin or an alkyl sulphate, and being deposited to form lightsensitive and filtering layers, subbing layers, and clear cover layers. A three-layer gelatine solution coating is described the first and third layers of which contain a yellow colloidal silver dispersion and a black metallic silver dispersion respectively. The deposited layers may be set chemically, for example in the case of protein layers, by including formaldehyde in one layer and ammonia in an adjacent layer, these materials reacting by diffusion across the layers. In another example a clear layer of polyvinyl alcohol containing saponin and borax and a similar layer also containing silver bromide were deposited and subsequently set by fuming with ammonia. Dual coatings of aqueous solutions of a salt of ethyl cellulose phthalate, one of which contains carbon black, and coatings of aqueous dispersions of an acrylate-acrylonitrile copolymer, are also referred to. Specifications 716,080 and 721,064 also are referred to.

Title: Improvements in and relating to the production of titanium carbides
IPC: C01B31/30
Filed: 1938-02-22
Abstract: 511,945. Titanium carbides. LEEMANS, J. P., and SOC. GENERALE METALLURGIQUE DE HOBOKEN. Feb. 22, 1938, No. 5611. [Class 1(ii)] Titanium carbides are obtained by subjecting an ore of titanium or a metallurgical byproduct containing titanium in oxide form to a reducing operation in the presence of a sufficient amount of iron and with the addition of an excess of carbon (e.g. coke, charcoal, &c.) to obtain an impure alloy containing iron and the titanium concentrated in the form of carbides and subjecting this impure alloy to a further treatment, e.g. crushing or granulation followed by a leaching with acid, for separating the titanium carbide. The iron may be initially present in the oxide form. The smelting operation may be conducted in an electric furnace. According to a modification the reducing operation is carried out in the presence of iron in an electric furnace, e.g. an arc furnace, the crucible part and/or the shaft part of which are wholly or in part made of carbon bricks or tamped with carbon. In this latter modification metal reducing agents such as aluminium, and/or magnesium and/or calcium may be added to the charge. An example relates to the use of ilmenite as the initial material, the subsequent extraction being effected with sulphuric acid and the solid residue being subjected to a mechanical concentration in order to separate the heavy carbide of titanium particles therefrom.

Title: Improvements in variable leverage brakes
IPC: B61H13/32
Filed: 1943-04-14
Abstract: 565,517. Brakes. SVENSKA AKTIEBOLAGET BROMSREGULATOR, and BROWALL, B. H. April 14, 1943, No. 5996. [Class 103 (i)] In vehicle brake mechanism, a spring arrangement against which the vehicle load or a part thereof acts to shift the fulcrum of a brakeapplying lever to vary the leverage in accordance with the load, is such that for a given change of the load it yields by an amount which decreases with the load, so as to compensate for the increase in the ratio of the shift of the fulcrum to the increase of leverage effected by the shift. In Figs. 1, 2, the vehicle load acts through the bearing springs 2, bellcrank levers 5 and pull-rods 6 on a semielliptic spring 7, the middle part of which is connected by a lever 9 and rod 11 to the fulcrum 12 of the lever 13 through which the brakeapplying cylinder 14 acts upon the transmitting mechanism 15. Since with a given change of the vehicle load the deflection of the spring 7 decreases as the load increases, the increase in the ratio of the movement of the fulcrum 12 to the increase of the leverage of the lever is compensated and the leverage thus increases in proportion to the increase in the load. Stops 16, 17 may be provided to limit the pull in the spring 7 and the movement of the lever 5 to the value corresponding to the load on the less loaded axle as explained in Specification 490,591 when the vehicle is non-uniformly loaded. In a modification, for the spring 7 there is substituted a helical spring disposed between diagonal pivots of a parallelogram linkage, the rods 6 being connected respectively to the other pair of diagonally disposed pivots. In a further arrangement, Fig. 7, the vehicle load acts through levers 5, 24 on a piston 22 which transmits the force hydraulically to a diaphragm attached to a conical piston 28 connected by a lever 31 to the brake lever fulcrum 12. Since the effective pressure area of the piston 28 decreases with its movement against the pressure of a spring 29, this movement decreases for a given increase of the vehicle load as the load increases. According to Fig. 8, the arms 41, 40 of a lever pivoted on a casing 36 are connected respectively to a lever such as 5, Figs. 1, 7, and to a lever 33 having rolling engagement with a fulcrum 43. The lever 33 is connected also to a piston 38 acting against a spring 34 and the shifting of the brake lever fulcrum 12 is preferably obtained by connection to the lever arm 41. Due to the change of the fulcrum point of the lever 33, the change in the compression of the spring for a given change in the vehicle load becomes smaller as the load increases. The piston 33 may, as shown, be immersed in liquid and be provided with a throttle port 45 to prevent movements of the lever 33 such as might otherwise be caused by shocks and jerks.

Abstract: 413,600. Connecting branch pipes to mains under pressure. TALBOT, F. W., Pitt, Winchester. Feb. 23, 1934, No. 6033. [Class 83 (iii).] A device for tapping and inserting a union in gas, water &c. mains comprises a cylinder 3 attached to a main 1 by a chain 7, a saddle 2 being placed between the cylinder and the main and being packed at 4, 5. A turret 9, packed at 10, is retained in the cylinder by a flange 8 and serves to support two rotatable spindles 11, 12, the former carrying a combined drill and tap 14 and the latter a union 15 to be attached to the main. The spindles are spaced at diametrically opposite points in the turret so that when the main has been drilled and tapped by the tool 14, rotation of the turret through 180‹ will bring the union 15 over the tapped hole. A pin 16 passing through a hole in the cylinder 3 registers with holes or longitudinal grooves in the turret to index it in the working positions and a screw 17 engages the lower surface of the turret to fix it in an axial direction. A screw 19 working in a bridge 18 pivoted to the cylinder serves to apply pressure to each of the spindles in turn. Specifications 467/04, [Class 83], and 326,114, [Class 99 (i)], are referred to.
