Title: Manufacture of easily soluble salts of sulphuric acid esters of leucovat-dyestuffs and process of dyeing and printing therewith
IPC: C09B9/00
Filed: 1933-04-12
Abstract: Leuco-vat dyes, sulphuric esters of.--Freely soluble salts of sulphuric acid esters of leuco-vat dyes are made by causing a sparingly soluble salt of the ester with a tertiary base, such as pyridine or dimethylaniline, to react with an alkylolamine of low volatility and removing the tertiary base by distillation.  The isolation of the alkylolamine salt is not essential; thus in dyeing or printing, the material is padded or printed with a padding solution or printing paste containing an alkylolamine salt of a sulphuric ester of a leuco-vat dye which is formed in the solution or paste by reaction between an alkylolamine of low volatility and a sparingly soluble salt of such an ester with a tertiary base such as pyridine or dimethylaniline.  On heating or steaming the tertiary base liberated is volatilized.  Ester salts of the following vat dyes may thus be prepared: dichloro- and dibromanthanthrones, pyranthrone and dibrompyranthrone, dibenzanthrone, isodibenzanthrone and derivatives, indanthrene and halogenated indanthrenes, thioindigo, naphthindigo and other indigoid vat-dyes, and in an example the triethanolamine salt of the leuco-sulphuric ester of symmetrical 2.1-naphthioindigo is prepared.  In further examples: (1) cotton is printed with a colour paste containing the pyridine salt of the leuco-sulphuric ester of dichloranthanthrone, triethanolamine, water and starch tragacanth thickening, and developed in an acid bichromate or nitrite bath; (2) cotton is printed with a paste containing the pyridine salt of the leuco-sulphuric ester of dichloranthanthrone, triethanolamine, ethylenethioglycol, starch tragacanth thickening, sodium chlorate, ammonium sulphocyanide, and ammonium vanadate, and the print steamed in the Mather-Platt apparatus. The triethanolamine may be replaced by diethanolamine, propanolamines, dipropanolamines, propanediolamine. Specifications 186,057 and 295,716, [both in Class 2 (iii)], are referred to.

Title: Process for the production of slabs, in particular imitation marble slabs, and the product obtained by this method
IPC: B44F9/04
Filed: 1948-04-21
Abstract: Marble slabs are made by mixing fibrous material with solid agglutinant to give partly coloured masses which, adequately wetted, are spread on at least one surface of a support and evenly covered with an aqueous binder, shaken, surplus water removed, pressed, hardened and then polished.  Asbestos is the preferred fibrous material and cement or an adhesive the agglutinant, which may have sand added thereto, whilst cement grout, with or without sand, is the binder.  The support may be a slab of cement and asbestos or a sheet of metal.  Powdered chalk is used to remove the surplus water.  The marble slabs may be reinforced and the support may have fixing means attached thereto.  The desired thickness of slab is obtained by passing the mixed mass through a pair of spaced rollers or a mixing drum has a fixed size outlet. Veins characteristic of the marble are traced before the binder is added.  Inert material, e.g. powdered cork may be included.

Abstract: 778,429. Hydraulic brakes. MORRIS MOTORS, Ltd. March 21, 1956 [April 16, 1955], No. 11016/55. Class 103 (1). In order to prevent the boiling of liquid in a hydraulic brake system adjacent to the wheel cylinders, when pressure is released therefrom after a brake application, means such as the valve unit assembly 9, is included in the system which will effect permanent pressurization of the fluid to a predetermined extent sufficient to raise its boiling point above the maximum temperature attained during operation of the brakes. As shown in Fig. 2, the valve unit comprises non-return two-way valves 10 and 11 of non-metallic oil resistant material, the setting of the valves being deterrnined by spacer elements 14.

Title: Improvements in or relating to cellular products
Inventor: DEYRUP ALDEN J
IPC: B29C59/00
Filed: 1963-03-20
Abstract: A dry closed cell foam having an average cell-size of 0.06-0.4 inches, an apparent density of 0.01-0.5 lbs./cu. ft. and a pneumatic compressive strength of at least 4 inches of mercury is prepared from polyvinyl alcohol and a gelling agent.  Polyvinyl alcohol is defined as the product obtained when 75-100% of the acetated groups in polyvinyl acetate are hydrolysed.  The gelling agent may be a thermally reversible one, e.g. Congo red.  The foam may also contain 20-70% of an infra-red transmission control agent which absorbs or reflects radiation of 5-25m  wave-length, e.g. aluminium powder or carbon black, a foam stabilizing agent, e.g. sodium lauryl sulphate, a thickening agent, e.g. a poly-saccharide, a flame-retardant, e.g. 10% boric acid, a rodent repellant, bactericide or fungicide and fibrous material.  The foam may be produced by mixing the solid materials in particulate form, adding to this water and optionally an acetate buffer and foaming the dispersion so formed. Foaming may be effected by a gas through an orifice into the aqueous mixture.  If a thermally reversible gelling agent is used the aqueous mixture will be a gel which must be melted before foaming.  The gas used must be less than 10% soluble in water at 25 DEG  C.  The wet foam is allowed to drain before solidification and a suitable apparatus for foaming and draining consists of a cylinder of approximately equal diameter and length disposed with its axis vertical and closed at the top and bottom by frusto-conical caps.  The air enters at the bottom of the lower cap, the foamable mixture enters horizontally further up the lower cap and the foam passes out at the top of the upper cap.  The wet foam may contains 0.5-5% polyvinyl alcohol and may have an apparent density of 1-5 lbs./cu. ft.  It may dry by natural evaporation or by cooling in the case of a thermally reversible gelling agent and may be used for insulating, acoustic and packing materials.

Abstract: 113,710. Kilburn, B. E. D., (Sulzer frÞres, Soc. Anon.). May 1, 1917. Heating buildings; radiators. - In order to obtain a more even heating and to facilitate the discharge of air from the heaters or radiators of a hotwater heating system in which the hot water is introduced at the lower end of the heaters. the water is discharged from the heaters both at the upper and lower ends. Fig. 1 illustrates a heater in which the water introduced by an inlet 3 is distributed to the elements 1 by a distributor 2 and discharged at outlets 4, 5, but the distributor 2 may be dispensed with. Air is conveyed from the heater through the upper outlet 5. Valves may be provided in the discharge pipes so as to regulate the temperature of the heater by controlling the total flow of water, and also the relative proportions of water discharged at the upper and lower outlets. In the arrangement shown in Fig. 3, two regulating-valves 6, 7 are provided, the upper one 6 being incapable of being entirely closed so that the discharge of air may always proceed. Instead, a single three-way valve may be arranged at the junction of the two outlet pipes 4, 5, or the two outlet pipes may be chosen of a definite relative cross-section and a single valve arranged beyond the junction of the two pipes 4, 5. In a further modification, Fig. 6, applicable to a heater with or without a distributor 2, the functions of the external discharge pipes 4, 5 are performed by an additional element 10 of the heater which has an open communication with the lower part of the adjacent element, but has a restricted communication 13 at the upper end through which air is discharged.

Abstract: 903,547. Improving commutation in D.C. machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 28, 1961 [March 31, 1960], No. 11458/60. Class 35. Sparking at the trailing edge of brushes in D.C. machines, particularly railway motors, is reduced by the provision of a discharge path through an auxiliary brush B2 connected through a transistor T1 which becomes biased to conduct at the instant the main brush leaves each segment. The biasing signal may be derived from a network R2, C1, as shown, or from a thin brush placed between the main and auxiliary brushes. For reversible machines, two such discharge paths are provided, one to be connected for each sense of rotation by means of switches or solid diodes. The transistor circuit may be improved by the use of a non- linear diode in place of resistor R2, and the gain of the transistor may be increased. In cases of over-commutation, the transistor may be reversed. Transients may be accommodated by a shunt condenser. The commutator segments may be spaced by inert conducting segments of equal width to the trailing auxiliary brushes. The auxiliary brushes may run on auxiliary commutator segments which may be in line with the main segments or displaced. They may be separated by inert segments.
