Title: Air pressure regulating and shut-off valve
IPC: F16K31/42
Filed: 1956-01-19
Abstract: 797,025. Fluid-pressure servomotor-control systems. BENDIX AVIATION CORPORATION. Jan. 19, 1956 [March 24, 1955], No. 1883/56. Class 135. Energization of a solenoid valve 26 closes a branch line 25 from a main duct 2 to an outer bellows 28, the inner bellows 32 being both coupled to the latter and normally at atmospheric pressure, and vents the bellows conduit 27 whereupon they collapse and move a piston valve 21 to the right, thus opening the top of a cylinder 15 to atmosphere via a port 17 and admitting air from line 25 upstream of the valve 26 to the bottom of the cylinder through a port 19, so elevating a spring-loaded piston 8, which through a piston-rod 12 and linkage 9, 10, opens a butterfly valve 7 in the duct 2 and allows air to flow to a starter turbine 4. The cylinder 15 has a dashpot 20. As the pressure builds up it effects a leftward movement of the inner bellows 32, after traversing a line 35, until the piston valve 21 is returned to the position shown, closing both ports 17, 19; at the same time the piston spring 16, which normally keeps the butterfly valve closed, progressively returns the latter towards the closed position until the desired flow to the turbine is attained. If the pressure in the line increases beyond this value the bellows 32 moves the piston valve to the left of the neutral position, thus venting the lower part of the cylinder 15 and admitting pressure air to the top thereof, so forcing the piston 8 downwards and further closing the butterfly valve 7 to reduce the pressure of air supplied to the turbine. As the pressure in line 35 changes, the piston valve will oscillate over ports 17, 19 to regulate the air pressure supplied to the turbine. Should line 35 break, excessive air pressure downstream of the butterfly valve 7 will act over a line 36 to move a piston 37 against a spring 38 and supply the inner bellows 32 via a channel 39. Upon de-energizing the valve 26 the outer bellows 28, connected to line 25, moves the pilot valve to cause downward movement of the piston 8, so closing the butterfly valve.

Abstract: A lubricating oil composition comprises a lubricating oil and a minor proportion of an oil-soluble polyvalent metal basic salt of a sulphonic acid having the general formula (R3C)n.Ar(OH)m.SO3H, where Ar is an aromatic hydrocarbon radical which may be partially hydrogenated and/or alkylated provided no tertiary carbon atom is present in the alkyl radical, the R's are the same or different alkyl radicals, which do not contain a tertiary carbon atom, n is 1, 2, 3 or 4, and m is 0, 1, 2 or 3, the sum of n and m not exceeding the number of valencies of the radical Ar which are available for bearing substituent groups.  The sulphonates may be prepared from benzene and its alkyl derivatives, such as the xylenes, ethyl benzene, styrene, durene, hemimelleitene and cumene, polynuclear aromatic hydrocarbons such as naphthalene and anthracene and their alkyl derivatives, and phenols such as o-cresol xylenol, a - and b -naphthol, and mono-, di- and tri-hydroxy benzenes, e.g. phenol and catechol.  The aromatic compound is alkylated (preferably with isobutylene or a polymer thereof) to introduce one or more alkyl groups R3C, sulphonated, and converted to polyvalent metal basic salt.  The metal may be an alkaline earth metal, aluminium, iron, tin, zinc, cadmium, indium, cobalt or nickel.  Example of salts which may be used are basic calcium tetra-tert. butyl naphthalene sulphonate and basic calcium dioctyl phenol sulphonate.  The salts may be used in amounts of 0.05 to 10 per cent., preferably 0.2 to 1.5 per cent., by weight based on the whole composition.  The lubricating oil may be oils distilled from paraffinic naphthenic, asphaltic or mixed base crudes; hydrogenated oils or white oils; synthetic oils prepared p  by polymerization of olefins or by hydrogenation of oxides of carbon or coal or its products; organic esters; animal, vegetable or fish oils or their hydrogenated, polymerized or voltolized products.  The compositions may contain solubilizing agents, preferably alcohols having eight or more carbon atoms, such as octyl, lauryl, cetyl, stearyl, heptadecyl alcohols, olefinic alcohols such as oleyl alcohol, alicyclic alcohols such as naphthenic alcohols, and alcohols containing aromatic groups such as phenyl-octyl alcohol and octadecylbenzyl alcohol.  The compostion may also contain dyes, pour-point depressors, sludge dispersers, foam suppressors, anti-oxidants, thickeners, viscosity index improvers and oiliness agents.  Compositions containing sulphonates not in accordance with the invention, which are also described, include those containing basic calcium salts of sulphonic acids of dinonyl naphthalene, di-dodecyl naphthalene, di-dodecyl phenol, dodecyl benzene, tetralin substituted with an alkyl group having 18 carbon atoms, and petroleum.
