Title: A starting cock for pressure operated change-over devices for reversing the direction of flow in feed water pre-heaters of locomotives and the like
IPC: F22D1/42
Filed: 1925-12-24
Abstract: 253,013. Knorr-Bremse Akt.-Ges., and Juliusburger, P. Dec. 24, 1925. Multiple - way plug cocks.-A control cock for controlling the supply and exhaust of actuating fluid to power cylinders actuating valves for reversing a the direction of flow in feed water pre-heaters of locomotives and the like is provided with two intermediate relief positions in which all the pressure chambers are connected to atmosphere. The Figure shows two sections of the cock, the ports shown in the upper section control a double acting cylinder, while those in the lower section control a single acting cylinder. Pressure fluid is supplied through a conduit 2, and in the position shown passes through a groove in the plug to a port 6 in the liner leading to a conduit 6a connected to one end of the doubleacting power cylinder. At the same time the conduit 9<a> leading to the other end of the cylinder is connected to the exhaust pipe 13 through ports 8 and 9 and groove 12. At the lower section pressure fluid entering by the pipe 3 passes through slot 14 into a semi-circular slot 15 out of the plane of the section and thence through port 16, groove 19, port 25, conduit 24 to the conduit 23 leading to the single-acting cylinder. If the plug is rotated in an anti-clockwise direction the first relief position is reached when the groove 11 connects with the port 7. In this position conduit 6a is connected to exhaust through port 6, groove 11, port 7, and groove 10, while conduit 9<a> is connected to atmosphere through port 9 groove 12, and port 8. Conduit 23 is connected to exhaust through ports 20, 25 and groove 19. A continued anticlockwise movement brings the cock to the second relief position in which the ports in the upper section remain as before, but the conduit 23 is now connected to a second exhaust conduit 21<a> through ports 21, 22 and groove 18. In the final position pressure fluid is admitted to conduits 9<a> and 23 while conduit 6a is connected to exhaust.

Abstract: 263,817. Still, C., [Firm of]. Dec. 28, 1925, [Convention date]. Coke ovens.-In a coke oven having alternative firing arrangements for rich and poor gas including two sets of regenerators which are used both for air, or one for air and one for gas, according to the nature of the gas in use, three sets of delivery passages, for air, rich gas, and lean gas respectively, are provided, and each set is employed for delivering exclusively the medium for which it is designed. In the oven shown having regenerator tunnels v, w running the length of the battery, and in which combustion is effected alternately in half-wall groups of vertical flues h, three distributing passages a, c, d for rich gas, poor gas, and air respectively, are associated with each half-wall. The passages a are connected directly to the rich gas main g, the passages c to the tunnel v through closable ports x, and the passages d to both tunnels v, w through closable ports y, z. When using rich gas the ports x are closed and air, supplied through both regenerators to the passages d, is delivered to the heating-flues through ports k in the partition walls. When poor gas is used the ports x are opened, the ports y are closed, and gas, supplied from a main m to the regenerator v, is delivered to the heating-flues through the passages c, the air being supplied through the regenerator w, passages d and ports k as before.
Patent GB-447072-A (GB)
Title: Improved process for the washing of textiles
IPC: C11D3/06
Filed: 1934-11-12
Abstract: Textiles, particularly animal and artificial fibres, are washed by means of aqueous solutions which contain in addition to an alkali pyrophosphate, water soluble salts of nuclear alkylized aryl sulphonic acids not containing amino groups.  The preferred alkali pyrophosphate is sodium pyrophosphate.  Other known washing, cleansing and bleaching agents may be added.  The required aqueous solutions are preferably made by mixing the solid components together in the desired proportion and dissolving the mixture in water.  In place of neutral pyrophosphate, acid alkali pyrophosphates may be used.  The preferred salts of the nuclear alkylized aryl sulphonic acids are the alkali and ammonium salts. Substituents which may be present in the aryl nucleus include hydroxyl, ether, ester and halogen groups.  In examples: (1) sodium isopropyl-naphthalene sulphonate, sodium sulphate, neutral sodium pyrophosphate, and a small amount of sodium perborate are mixed, dissolved in water, and used specially for washing wool; (2) sodium dibutyl-naphthalene sulphonate, neutral sodium pyrophosphate and sodium bicarbonate forms a mixture which may be employed in 0,5--1 per cent concentration for washing wool and artificial silk.  Borax may replace the sodium bicarbonate if desired.  A table is given showing the influence of varying amounts of sodium pyrophosphate on the lathering power of isopropyl-naphthalene sulphonic acid.  Specifications 394,989, 435,861, 437,128, 438,063, and 443,487 are referred to.
