Title: A new or improved method or process of treating the surfaces of articles for the purpose of giving them a polished or highly glazed surface
IPC: B05D7/10
Filed: 1925-03-04
Abstract: 252,782. Logan, W. F. March 4, 1925. Coating processes; fillers; polishing-compositions.-The surfaces of articles are given a glaze or polish by coating the surface with a nitro-cellulose solution or varnish, rubbing down the coating and polishing it with a pad and amyl or ethyl acetate or with Fullers earth or a substance containing it. A filler may first be applied to the surface. A suitable filler for a wood surface comprises Japan, Stucco or silicate and turpentine, while for a metal surface, Japan, barytes and white lead, in admixture, may be used; or a nitro-cellulose filler may be employed alone or in addition to other fillers. The surface may receive one or more coats of paint after the filler, a suitable paint comprising nitro-cellulose, pigments and amyl acetate. The paint surface is rubbed down with sandpaper or pumice before the application of the nitro-cellulose solution which may be coloured with pigments if desired. The nitro-cellulose coating is rubbed down with abrasive, and either treated with amyl or ethyl acetate and finally with wax polish, or with an abrasive polishing paste and finished with Fullers earth mixed with wax or suspended in petroleum spirit. The Provisional Specification describes the use of a nitro-cellulose filler comprising collodion, barytes, whiting and white lead and also the use of a mixture of Vienna lime and petroleum spirit or like solvent as a polishing medium.

Filed: 1962-02-19
Abstract: Stable polymer compositions comprise a water soluble acrylamide polymer and a water soluble salt of nitrous acid in a proportion substantially to reduce break down of the polymer during storage or upon exposure to chemical attack. Preferred nitrites are alkali metal, alkaline earth metal and ammonium nitrites.  The compositions may also contain a water soluble iodide, preferably an alkali metal, alkaline earth metal or ammonium iodide.  The acrylamide polymer may be a homopolymer or a copolymer of acrylamide with hydrophilic monomers, e.g. methacrylamide, acrylic acid, methacrylic acid or a quaternary vinylbenzyl ammonium salt, or hydrophobic monomers, e.g. ethylene, styrene, vinyl chloride, vinylidene chloride or alkyl esters of acrylic and methacrylic acids.  The compositions may be in solid form or in the form of aqueous solutions, and may be prepared by dissolving the polymers and salts in water, and optionally removing at least part of the water by evaporation to reduce the composition to solid form. Specified nitrites are sodium, potassium, lithium, cesium, magnesium, calcium and ammonium nitrites, and examples describe the stabilisation of aqueous solutions of a homopolymer of acrylamide in which about 5% of the amide groups are hydrolyzed to carboxyl groups with (1 and 2) sodium nitrite and (3) sodium nitrite and a mixture of sodium nitrite and potassium iodide.

Title: Improved process for the manufacture of vat dyestuffs of the anthraquinone series
IPC: C09B5/34
Filed: 1927-03-10
Abstract: 291,878. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). March 10, 1927. 1 : 1<1> - Dianthraquinonylamine-2-aldehydes; dianthraquinone-acridones.-1-Aminoanthraquinone- 2-aldehyde is condensed with a 1-halogenanthraquinone, or a derivative or substitution product thereof, in presence of an acid-binding agent and a catalyst of the kind facilitating the elimination of hydrogen halide such as a metal or metal salt particularly copper or a copper salt. The 1 : 1<1>- dianthraquinonylamine-2-aldehydes so obtained yield condensation products with aniline and are converted by treatment with acids or alkalies into dianthraquinoneacridones which dye cotton from the vat; the conversion can be effected even by vatting with alkali and hydrosulphite though it is preferred to purify the dianthraquinonylaminealdehyde by precipitation from sulphuric acid and then effect conversion into the acridone bv heating the acid paste either directly or with caustic soda solution. According to examples (1) 1-aminoanthraquinone-2-aldehyde is condensed with 1-chloranthraquinone in presence of nitrobenzene, sodium acetate, and copper powder; the product yields with alkaline hydrosulphite a vat from which cotton is dyed in dull brown-yellow shades, but if the product is precipitated by water from a sulphuric acid solution and the paste boiled with or without caustic soda and then vatted, the vat dyes cotton clear brownyellow shades; (2) 1-aminoanthraquinone-2-aldehyde is condensed similarly with 1-benzovlamino- 4- or 5-chloranthraquinone and the products precipitated from sulphuric acid solutions and the pastes boiled; they dye cotton from the vat in brown-orange and dark blue-violet shades respectively.

Title: Means for heating district-heating water in power and district-heating plants
IPC: F01K17/02
Filed: 1966-02-16
Abstract: 1,091,831. Automatic control systems. STAL LAVAL TURBIN A. B. Feb.16, 1966 [Feb. 26, 1965], No.6773/66. Heading G3R. [Also in Divisions F1 and F4] In a steam turbine plant comprising a highpressure turbine (not shown) preceding a lowpressure turbine set comprising a contra-rotating radial-flow turbine 7 exhausting through pipes 16, 17 to axial-flow turbines 10, 11 and 12, 13, steam is bled through pipes 23, 25 to condensers 24, 26 where it is used to heat water which is passed through the condensers in series, the water being used for district heating. The steam supplied to the condenser 26 is at a higher pressure than that supplied to the condenser 24. To keep the hot water at a constant temperature, the amount of steam diverted to each condenser 24, is varied in accordance with the steam pressure in each condenser by adjustment of a respective interstage throttle valve 18 or 19. For this purpose, the pressure in condenser 24 is sensed by a sensor 29 and applied through a conductor 31 as an electric signal to a proportional link 33, where it is added to a signal from an adjustable potentiometer 35 representing the desired pressure and to a restoring signal transmitted through a conductor 37 from a position sensor (not shown) of an electrically controlled hydraulic servomotor 67 which actuates the valve 18. The resultant signal is transmitted from the proportional link 33 to the control magnet of the servomotor 67 via switches 58, 39, an amplifier and a conductor 41. A similar arrangement is provided for controlling the valve 19 associated with the condenser 26. If, when the valves 18, 19 are fully open, the temperature of the hot water is still too high, the supply of steam to the condenser 26 can be further reduced by a throttle valve 43 actuated by a servomotor 65 in accordance with the steam pressure in the condenser 26, the control circuit being similar to that for the servomotor 67. A similar arrangement may be provided for reducing the supply of steam to the condenser 24. If the hot water is too hot even when the valve 43 is closed, a by-pass 50 around the condenser 24 or a by-pass 51 around both condensers 24, 26 can be opened by respective throttle valves 52, 53 controlled by temperature sensors 54, 55. If the steam pressure upstream of valve 43 becomes excessive, a pressure governor 56 adjusts throttle valves 5, 6 at the inlet to the turbine 7. Instead of being controlled in accordance with the pressure in condenser 24, the servomotor 67 can be controlled by the servomotor 68 so that it maintains a positional difference relative to the latter. For this purpose switch 58 is operated to connect the servomotor 67 to a proportional link 57 which is connected via conductors 61, 62 to the position sensors of both servomotors and also to a potentiometer 60 for setting the desired positional difference.
