Title: Fluid pressure operated valve devices
IPC: B60T15/04
Filed: 1977-04-04
Abstract: 1528885 Railway vehicle brake control valves WESTINGHOUSE AIR BRAKE CO 4 April 1977 [5 April 1976] 14168/77 Heading F2F A braking control valve 5, for use with a brake cylinder 2, an emergency reservoir 3 and an auxiliary reservoir. 4 comprises a first valve spool 18 movable (upwards) in response to a drop in train pipe (1) pressure acting in a chamber 24 relative to auxiliary reservoir pressure acting in a chamber 25 to supply fluid to two further valve spools 61 and 78 to move them from first positions, to which they are spring biased and wherein they vent the brake cylinder to atmosphere (both by passage 53 and via retainer valve device 84) to second positions in which the valve spools 78 and 61 respectively cut-off the brake cylinder from the vent passage 53 and connect it to the auxiliary reservoir 4 for braking. On initial train pipe pressure reduction, lifting the valve spool 18 from the position shown, the charging connection 138 to 48 from the brake pipe to the reservoirs 3, 4 is broken, the quick service chamber 54 is cut-off from the vent passage 53, and auxiliary reservoir pressure from passage 88 lowers the valve spool 78 cutting off the brake cylinder passage 70 from venting (Fig. 2, not shown). On further train pipe pressure drop the spring 92 shortens (Fig. 3, not shown) and chamber 54 is charged from the train pipe via passages 52 and 138, fluid flowing thence to the brake cylinder 2 via passages 130, a brake cylinder pressure limiting spool valve 115, the spool valves 78, 61 and passages 69, 73. The valve 115 closes, to limit the braking pressure derived from the quick service chamber 54 to a set value, when the braking pressure in chamber 124 is sufficient to lift a diaphragm 116 and the valve spool 117 against bias spring 126. Still further train pipe pressure reduction lifts the spool 18 fully (Fig. 4, not shown) permitting fluid to flow via passages 88 and 58 from the auxiliary reservoir to the top of valve spool 61 depressing it. This allows flow to the brake cylinder 2 from the auxiliary reservoir 4 and the chamber 25 via passages 87 and 69 and groove 66 of the valve 61. Accelerated brake release is provided by a valve 64 with a diaphragm 94 which is lowered, because the train pipe press acting in chamber 99 increases faster than the auxiliary reservoir pressure acting in the chamber 100, opening the valve disc 104 and thereby connecting the charged emergency reservoir 3 to the train pipe via check valve 11 and a chamber 27.

Title: Process for preparing detergent compositions
IPC: C11D3/34
Filed: 1953-05-21
Abstract: Wetting, sudsing and detergent agents having improved anti-caking properties in small solid particle form are prepared by sulphonating an alkyl aryl compound or a mixture thereof with a hydroxyl alkyl compound, in each case containing at least 8 carbon atoms in the alkyl chain, with such an excess of a sulphating agent which is oleum, SO3 or sulphuric acid that the mixture from said sulphonation contains about 90-99 per cent, preferably 96 to 99 per cent, strength sulphuric acid, thereafter admixing with a mono-hydroxy alcohol having not more than 6 carbon atoms to cause sulphation thereof, the amount of such alcohol being sufficient to improve the anti-caking properties of the final product, allowing sulphation of the monohydroxy alcohol to proceed to substantial completion without the formation of over-sulphated products, e.g. for a time of 20-30 seconds, the temperature of the sulphation being restrained from rising above about 125 DEG  F., thereafter neutralizing the final product including any remaining acid with an alkaline material and drying to solid granular form.  The preferred sulphating agent is oleum containing 10-25 per cent free SO3 but even 100 per cent SO3 may be used.  It is preferred to keep the temperature above 110 DEG F. to prevent solidification.  The monohydroxy alcohol is normally added in an amount to give 2 to 6 or 7 per cent by weight of alkyl sulphate in the product.  Preferred alcohols are methyl, ethyl and isopropyl.  The process may be a batch or continuous process, the preferred method of introducing the low molecular weight alcohol in a continuous manner being to inject the alcohol into the line through which the acid mix from the primary sulphonation passes. The product is preferably spray-dried but drum-drying or roll-drying may be used. In examples (1) dodecyl benzene is sulphonated with oleum containing 10 to 25 per cent free SO3 in a dominant bath apparatus.  The time and temperature are controlled to give an excess acid strength of 96 to 99 per cent. In three runs, isopropyl alcohol is injected in amounts sufficient to give 2, 4 and 7 per cent sodium isopropyl sulphate in the product.  In other runs, methyl or ethyl alcohol is added.  The temperature is maintained below 125 DEG  F. and the reaction proceeds for 20 or 30 seconds before neutralization with aqueous sodium hydroxide.  The product is spray-dried.  Data is given showing the caking values of the products; (2) the procedure of example (1) is followed to incorporate sodium isopropyl sulphate into an alkyl benzene detergent, the alkyl chain being about 12 carbon atoms; (3) the procedure of example (1) is used to incorporate sodium methyl sulphate into a detergent containing 75 per cent of an alkyl benzene sulphonate containing an average of 12 carbon atoms in the alkyl chain and 25 per cent of an alkyl sulphate, the alkyl chain of which is obtained from coconut oil fatty alcohols.
