Patent GB-390520-A (GB)
Title: A process for the manufacture of a coloured facing
IPC: B44C1/10
Filed: 1931-10-03
Abstract: A coloured facing layer for building or decorating purposes, such as a wall panel, ceiling-plate, or veneering for furniture, is produced by spraying nitrocellulose varnish on to a supporting surface, which has previously been coated with a thin layer of an easily softened material, securing a layer of fabric to the film, heating the easily softened material in the presence or absence of water or steam, and stripping the film with the fabric layer.  The film is made of the desired thickness by repeated spraying of the nitrocellulose solution.  The supporting surface may be plain or provided with reliefs.  After removal from the film-forming surface, the film with the fabric layer may be secured to plywood, or a plate made of compressed vegetable fibres.  Alternatively, while the film is still on the forming surface, a fabric layer may be fixed to it by cement and a reinforcement plate may be fixed to the fabric, or a layer of a quickly setting or hardening material such as gypsum may be poured over the fabric and if desired this layer may also be strengthened by wire gauze.  In an example, a glass, stone, marble, or other flat surface is sprayed with a mixture of resin, wax, ceresine, soap, and oil, or a mixture of chalk, glycerine, and water.  Thin layers of nitrocellulose varnishes are sprayed on to the prepared surface. Ornamental effects are obtained by providing layers of different colours or alternating coloured and uncoloured layers and by the use of stencils.  A fabric web is secured by pressure and adhesive to the film.  A reinforcement plate of compressed fibres, or of plywood is secured to the fabric, or a layer of gypsum is poured over it. The layer between the film and the forming surface is softened by heat or hot water or steam according to its composition, and the film with its reinforcement layers is detached.  When the forming surface is coated with chalk, glycerine and water, a dull surface is imparted to the film.

Title: Process and apparatus for feeding solids into or removing solids from vessels under pressure
IPC: C10G1/06
Filed: 1925-11-05
Abstract: 262,901. Johnson, J. Y., (Badische Anilin & Soda Fabrik.) Nov. 5, 1925. Charging and discharging.-Solid materials are fed into, or removed from, vessels in which gases or liquids are maintained at a high pressure of 100 atmospheres or over, by forcing them in known manner through a tube or cylinder in connection with the vessel in the form of a compressed body which tightly closes the tube or cylinder and prevents the escape of gas &c. from the vessel. The solids are preferably of a soft and slightly caking character, and the formation of the gas-tight body may be assisted by adding to the solids a substance which will cause the solids to cake together to form a tight core. As shown, Fig. 1, the solid material in the form of powder or grains is contained in a hopper B, and is fed through a tube D at the upper part of the high-pressure vessel A by means of a piston C reciprocated by a crank-shaft. On the forward movement of the piston, a portion of the loose material within the tube D is added and compressed to the already formed core or stopper E, the whole moved forward and the foremost part of the stopper introduced into the vessel. When the material in the hopper is not in a condition to secure a gas-tight stopper, a layer or sheet F of gas-tight material is introduced at each forward stroke of the piston so that the stopper E contains a number of gas-tight sheets as shown in Fig. 3. The layers or sheets F may consist of rubber, paper, cardboard, metal, &c. A suitable guide may be arranged inside the vessel A near the entrance of the stopper to break off the end of the stopper. The tube D may be slightly conical with the smaller end towards the piston. The method is applicable for introducing soft coal, lignite, &c. into a vessel for being heated therein in the presence of a gas containing hydrogen and being converted into liquid fuels by a hydrogenating process. Specification 1409/04 is referred to.

IPC: C09K17/48
Filed: 1960-08-12
Abstract: 908,868. Soil stabilization. ALGINATE INDUSTRIES Ltd. July 28, 1961 [Aug. 12, 1960; April 17, 1961], Nos. 28012/60 and 13763/61. Class 68 (1). A process for preventing seepage while excavation, tunnelling or dam building is in progress comprises impregnating the ground near the workings with a solution of a soluble alginate and a polyvalent metal compound, e.g. calcium phosphates, copper carbonate or zinc oxide, which will react to form an insoluble alginate when the pH is lowered and lowering the pH to form the insoluble alginate in situ. This process may be supplemented by the addition of resin-forming components such as urea formaldehyde precondensates. The pH may be lowered by mixing the ammonium salt of a weak acid and formaldehyde thus producing hydrogen ions slowly and the onset of this reaction may be delayed by the addition of a sequestering agent such as glassy ammonium meta phosphate.

Title: Process for the production of resorcinol
Inventor: GRAHAM ARCHIBALD ROBERT
IPC: C07C39/08
Filed: 1954-09-29
Abstract: Resorcinol is prepared by decomposing m-di-isopropylbenzene dihydroperoxide in a ketonic solvent in the presence of sulphuric acid to give an acid reaction product which is treated with an aqueous alkali metal hydroxide solution to give a pH of 2.5-4.0, before recovery of the resorcinol.  Neutralization to within the pH range specified gives a crystalline filterable precipitate of alkali metal sulphate which may be removed by filtration or decantation. The alkali metal hydroxide is preferably sodium hydroxide.  The ketonic solvents are preferably aliphatic ketones having between 3 and 6 carbon atoms such as acetone, or mixtures thereof with methyl ethyl ketone or methyl isobutyl ketone.  The process may be carried out batchwise or continuously.  In the preferred continuous process the decomposition reaction product is continuously fed to a stirred vessel fitted with an overflow concurrently with an aqueous sodium hydroxide solution to give a pH of 2.5-4.0.  The treated product continuously overflows and is filtered and treated for recovery of resorcinol.  In examples solutions of sulphuric acid in acetone are mixed with solutions of m-di-isopropylbenzene dihydroperoxide in acetone, methyl ethyl ketone or methyl isobutyl ketone, stirred and heated, the decomposition products being neutralized with varying amounts of sodium hydroxide solution and the filtration properties at various pH values compared.  Specification 676,771 is referred to.

Abstract: 858,223. Bird scarers. NORTH, R., and KINSMAN, H. J. A. Aug. 18, 1959, No. 28271/59. Class 6(2). A bird scarer of the construction described in Specification 858,222 is mounted on a support 10 so as to be capable of tilting and rotating relative to the support, the tilting being spring controlled. As shown in Fig. 1, the mounting comprises a tube 31 fixed to the support 10 and having inside it a spring 40 which is secured at its lower end to the closed lower end of the tube, and at its upper end is attached to a bearing member 37 seated within the open upper end of the tube. The member 37 is integral with a spindle 23 rotatably housed in a sleeve 14 inserted in the tube 15 which forms part of the construction of the figure 17. Thus the figure can rotate about the spindle 13, and the spindle can tilt by virtue of the movement of the members 37, within the tube 31, this latter movement being resisted by the spring 40. In one modification, the projection 39 of the member 37, to which the upper end of the spring is connected, is lengthened to abut against the inside of the tube as the figure tilts, thereby limiting the tilting of the figure. As shown in Fig. 3, the spindle 13 is connected to a link 51 which passes through the base of the tube 31 ,a compression spring 54 being interposed between a disc 52 at the lower end of the link, and the base of the tube. In the modification shown in Fig. 5, a coiled spring 56 is connected directly between the lower end of the spindle and the upper end of the support . In the embodiments shown in Figs. 1 and 3, the tension of the spring is adjustable.
