Title: A new or improved hot water supply system
IPC: A47J31/56
Filed: 1925-10-16
Abstract: 260,753. Marsh, R. G. Oct. 16, 1925. Water supply and delivery; safety - arrangements. - For supplying water that will boil on issuing from the delivery cock j a boiler a is connected to an overhead tank c and is maintained at such a temperature above boiling point that the pressure prevents the formation of steam. The delivery cocks are arranged upon standards or fountains e connected with the boiler by flow and return pipes d, g. An automatic air release valve is provided on each standard. The temperature is normally maintained thermostatically but if an abnormal increase in pressure occurs the control is cut out and the gas is shut off. This may be effected by the rise in water level in the tank c consequent on the formation of steam. As shown in Figs. 1 and 4 water overflowing the weir v passes down the pipe u and, striking against a plate t in a casing s, turns off the gas cock, the spindle r<1> of which is connected to the plate t. In the example shown in Fig. 5 overflowing water fills the chamber w and then siphons down the pipe x to cut off the gas supply passing through a closed chamber y. In Fig. 6 a siphon in the tank c operates to cause water passing down the pipe 1 to press a diaphragm 5 against the end of the gas supply pipe 6.

Abstract: 881,805. Curling fibres. RUHRMANN, J. Aug. 13, 1958 [Aug. 21, 1957; June 27, 1958], No. 26041/58. Classes 120(2) and 120(3) [Also in Group XXII] A machine, for forming a pair of meshing coils comprising two nylon filaments of oblong cross-section helically wound together in opposite directions, includes two coiling heads which are rotated in opposite directions and which carry filament guides moving through intersecting orbital paths passing around a mandrel which is floatingly supported between the intersecting parts of the paths so that the heads are able to pass the filaments in opposite directions around the end of the mandrel as the heads rotate. As shown in Fig. 2, a filament F2, from a reel 33 mounted on a shaft 25 and braked by a shoe 71 pressing on a flange 33a of reel 33, passes over guide pulleys 36, 37, 38, 40, and through a bore 41 in rotating shaft 25 to be wrapped around a mandrel 20 with a similar filament F1. The mandrel 20 is supported intermittently by arcuate flanges 43, 44, on the heads 21, 22, and has a needle-like portion along which coils pass between guide surfaces 49 (which may be heated) moved by vibrators 86, 87, to feed the coils along the mandrel to sprockets 88, 89. Each head 21, 22, includes an arm 50, 51, curved to engage the upper surface of the bulbous base of mandrel 20, and moved intermittently out of contact by a shaft 52 rocked by mechanism, Fig. 9 (not shown) within a bearing block 31 to permit filaments F1, F2, to pass under the arms 50, 51. The needle-like portion of mandrel 20 may be mounted slightly eccentric of the heads 21, 22, so that the distance covered by the filaments from the two heads remains constant throughout coiling. As shown in Fig. 11, filament from a spool 153, retarded by a brake shoe 155 on a flange of the spool, passes over pulleys 157, 158, 159, 160, through a shaft 151, and a second shaft 135 having a laterally extending tip 166 to compensate for differences in the distance covered by the filament, to a coiling head 121 comprising arms 124 having enlargements 129 through one of which the filament passes. The lower portion of the mandrel 170 rests on the arms 124, while the enlarged portions 129 of the meshed portions of the two heads 121, 122, prevent lateral motion of mandrel 170. Other embodiments of coiling head showing various methods of supporting the mandrel and compensating for differences in distance covered are described with reference to Figs. 12-14 (not shown).

Title: An improved method of protecting the interior surfaces of oil tanks from corrosion
Inventor: MAY GEORGE
IPC: C04B28/06
Filed: 1952-10-17
Abstract: 721,510. Preventing corrosion. V. G. (LONDON), Ltd. Sept. 8, 1953, [Oct. 17, 1952], No. 26134/52. Class 123 (1). Corrosion of the interior surfaces of oil tanks, especially in tanker ships, is prevented by applying to the degreased surfaces at least two thin layers of hydraulic cement admixed with an aqueous suspension of an oil-resistant synthetic resin, the layers having a tough woven fabric sandwiched between them. The resin, which may be polyvinyl chloride or acetate, a mixture of polyvinyl chloride and synthetic rubber, polystyrene; polyacrylates or methacrylates, is used in the form of an aqueous suspension having about 50 per cent solids content. In an example the composition comprises 10 parts by weight of a 50 per cent polyvinyl acetate aqueous suspension, 75 parts of high-alumine cement and 20 parts of water, a filler such as asbestos fibre or cork dust being incorporated if desired. The composition is brushed or sprayed on to the surface to form a first layer, preferably from 1/20 inch to 1/40 inch thick, and a woven fabric such as hessian or glass cloth is pressed on to the first layer before it has set. A second layer of the composition is then applied over the hessian and, when set, is covered with an oil and water-resisting varnish.

Filed: 1937-09-28
Abstract: 503,082. Luminescent materials. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. Sept. 28, 1937, No. 26238. [Class 39 (i)] An electric incandescent lamp with a metal filament has a bulb of transparent or translucent material which is provided with a coating of luminescent material adapted to be excited by radiations from the filament of not less than 3,200 Angstrom units to transform these radiations into visible radiations. The material of the bulb determines whether the luminescent material is applied to the inside or outside thereof, e.g. if the bulb is opaque to ultra-violet radiations the luminescent material is applied to the inside surface. In the case of a quartz bulb the luminescent material may be applied to the inside or outside, or both inside and outside. The luminescent effect is increased if the size of the bulb is greater than that used for ordinary nitrogen-argon filled lamps of the same wattage, the diameter of the bulb being about 1¢ to 2 times the diameter of the ordinary lamp. The luminescent material is applied as powder to an adhesive sprayed on the bulb, or the powder may be mixed with a vaporizable binder and the mixture applied to the bulb in a layer and then dried. Blue fluorescence may be obtained by using a material in the zincsulphide class, and orange to red by materials in the zinc-cadmium-sulphide class, one of the phosphorogens, manganese, silver, copper, or bismuth also being used.

Title: An improved manufacture of cellulose derivative coating compositions
IPC: C09D101/08
Filed: 1939-09-22
Abstract: 534,674. Cellulose derivative compositions. STANDARD OIL DEVELOPMENT CO. Sept. 22, 1939, No. 26440. Convention date, Oct. 19, 1938. [Class 2 (ii)] A clear coating composition resistant to acids and alkalis comprises a cellulose ester or ether, a product obtained by the halogenation of an aliphatic hydrocarbon polymer having a molecular weight above 1,000 and an iodine number below 50, a non-volatile mutual solvent for these, and a volatile solvent, the non-volatile solvent being present in such amount as to maintain the halogenated hydrocarbon polymer in true solution in the coating or film. The viscosity of the medium may be reduced by the addition of such other volatile or non-volatile solvents or non-solvents, as do not preferentially precipitate out the non-volatile components on drying. Pigments, fillers and dyes may be added. Cellulose esters and ethers mentioned include nitro-, benzyl-, ethyl-, methyl-, propyl-, isopropyl-, and butylcelluloses and cellulose acetate. Esters of higher acids such as cellulose naphthenate, trilaurate and palmitate give more compatible films. The preferred hydrocarbon polymers have a molecular weight above 5, 000, an iodine number less than 10 and contain at least 10 per cent. of halogen. Thus olefines, more especially isoolefines such as isobutylene or 2-methyl butene-1 may be polymerized at low temperatures (-50‹ to-80‹C.) in the presence of an active halide catalyst, and then chlorinated preferably in direct sun or ultra-violet light, at temperatures below 70‹C. Other polymers are those formed by reacting isoolefines with diolefines, e.g. isobutylene with butadiene, and polymers of beta unsaturated isoolefines and of ethylene. Chlorinated hydrogenated rubber may also be used. Suitable non-volatile solvents or plasticizers are tricresyl phosphate, dibutyl phthalate, triphenyl phosphate, methyl phthalyl ethyl glycollate, camphor, methyl cyclohexyl adipate, triacetin, benzyl benzoate, and hydrogenated abietic acid esters. Additional solvents for the chlorinated isobutylene polymers include amyl acetate, esters of wax acids, methyl propyl ketone, isopropyl acetate, cyclohexanone, tributyl phosphate and butyl sulphone. As volatile solvents are mentioned, esters such as ethyl acetate, butyl acetate and butyl propionate or ketones such as acetone, methyl ethyl ketone or cyclohexanone may be used ; alcohols (e.g. ethyl, isopropyl, secondary butyl, and amyl alcohols) act as solvents with ketones or esters. As non-solvents for reducing viscosity are mentioned, benzol, toluol, xylol, petroleum naphthas, and hydrocarbons obtained by the SO  2  extraction of petroleum or cracked naphthas. In one example, 6 parts nitrocellulose, 6 parts chlorinated isobutylene polymers, and 6 parts tricresyl phosphate are mixed with a solvent consisting of 10 parts ethyl acetate, 8 parts butyl acetate, 5 parts butyl alcohol, 26 parts toluol and 4 parts SO 2  extract of crude petroleum boiling at 200‹-275‹F.
