Abstract: 163,857. Svensson, J. A. March 20, 1920. Compound piston pumps; pump-actuating mechanism; valves, arrangement of. - In two-stage compressors having rotary distributing - valves carried by the driving-shaft, which reciprocates the pistons by means of an oscillating or oblique member on the shaft, this driving-device is arranged in a central closed chamber, and the low and high pressure cylinders are mounted on opposite sides of the chamber, the air inlet and outlet being at opposite ends of the apparatus, an intermediate air chamber is disposed next to the central chamber forming substantially a single chamber therewith enclosing air at uniform pressure, the low-pressure valve supplying air thereto and the high-pressure valve receiving air therefrom. In the apparatus shown, a driving-shaft 2 is supported in antifriction bearings and journaled at one end in a closed chamber 4, the other end projecting for the application of power. The shaft carries an oblique crank 5 on which a sleeve member 6 can rotate, carrying rods 14 connected to cross-heads 12, which move in guides 13 and actuate the low and high pressure pistons through their rods. The crank 5 is enclosed in a chamber 7. The low and high pressure compressors are double-acting; air is admitted to the low-pressure cylinders through an inlet 15 and ports 17 controlled by a rotary sleeve valve 16, and is delivered through the same ports and a passage 18 to an intermediate chamber, which may be cooled, and from which the air is delivered through a pipe 22 and ports 21 to the high-pressure cylinders from which they are delivered by the same ports to a discharge pipe controlled by a valve 23. The ports 21 are controlled by a rotary sleeve valve 20 mounted, like the valve 16 of the low-pressure cylinders, on the driving-shaft.

Filed: 1957-03-14
Abstract: A lubricating oil composition comprises (a) a synthetic lubricating oil consisting of 80-99 vol. per cent of a dialkyl ester of a dibasic acid of formula ROOC(CH2)nCOOR and 1 to 20 vol. per cent of a complex ester of formula <FORM:0811813/III/1> where R is a C6-10 branched chain alkyl group, n and x are integers from 2 to 8 and z is an integer from 2 to 6; and by weight (based on (a)), (b) 2 to 25 per cent of a dimethyl silicone polymer having a viscosity of 3-20 co./25 DEG  C.; and (c) 0.0001-0.1 per cent of a dimethyl silicone polymer having a viscosity of 10,000 to 1000,000 cs./25 DEG  C.  The complex ester is prepared by the reaction of a C6-10 branched chain alcohol (e.g. 2-ethyl hexanol, C8 oxo alcohol), a C4-10 dibasic acid (e.g. sebacic, adipic) and a C4-12 glycol (e.g. tetraethylene glycol).  The viscosities of the preferred diesters and complex esters are 2.7 to 3.5 cs./210 DEG  F. and 5,000 to 10,000 cs./-65 DEG  F. and 7 to 11 cs./210 DEG  F. and 100,000 to 500,000 cs./-65 DEG  F. respectively. The lighter silicone (b) acts as an E.P. agent and the heavier silicone (c) reduces foaming.  Minor amounts of antioxidants, e.g. phenothiazine, phenyl alpha naphthylamine, n-butyryl p-amino phenol and 2,6-di-t-butyl-p-cresol may also be added.  In examples, the diester is diisooctyl azelate, 2-ethylhexyl sebacate, or a mixture of C8 and C10 oxo adipates; the complex ester is formed from either 2-ethylhexanol/sebacic acid/tetraethylene glycol/sebacic acid/2-ethylhexanol or C8 oxo alcohol/adipic acid/tetraethylene glycol/adipic acid/C8 oxo alcohol; the dimethyl silicones have viscosities at 25 DEG  C. of 10 cs. and 60,000 cs.; and 1 per cent by weight of phenothiazine is added as antioxidant.  One example also includes 1 per cent of tricresyl phosphate.

Title: Improvements in or relating to hydraulic mine roof supports
Inventor: TAYLOR LAWRENCE WILLIAM
IPC: E21D23/00
Filed: 1962-03-07
Abstract: 1,031,501. Advancing mine roof supports; reciprocating pumps. W. E. & F. DOBSON Ltd. March 5, 1963 [March 7, 1962; Feb. 22, 1963], Nos. 8724/62 and 7155/63. Headings F1A and F1P. In a mine roof support comprising a pair of hydraulic props interconnected by a horizontal double acting hydraulic jack 3, Figs. 5 and 6 (not shown), controlled by a two position hand operated valve 18 adapted to connect either end of the jack cylinder 10 to the output 26 from a manual pump so that the props may be alternately advanced, a control valve 43 is provided which automatically operates to cause the prop secured to the ram 12 of the jack to advance slowly if heavily resisted and to advance quickly if only lightly resisted. The automatic valve 43 comprises a valve member 47 having collars 47a, 47b, 47c, 47f slidable in an intermediate part 43a against the action of a coil spring 49 located in a chamber 48 in an upper part 43b. A lower part 43c has a bore 50 axially aligned with the valve member 47 and containing a plunger 51 urged towards the valve member 47 by a spring 51c. The props are each separately extendible and retractable by the manual operation of pumps located therein. To advance the pron connected to the ram 12 it is retracted from engagement with the roof and the valve 18 is operated whereby fluid flows from the outlet 26 to the side 10b of the jack cylinder. If the resistance to advance of the prop is great, pressure in a pipe 45 connected to the pump outlet 26 rises and acting through passages 52, 53 raises the plunger 51 and valve member 47, whereby fluid displaced from the other side 10c of the cylinder flows through a pipe 15 and channels 47g in the collar 47f to a pipe 17 leading to a reservoir 19 via the valve 18. The backpressure in the pipe 15 due to the throttling effect of the channels 47g causes the prop to advance at low speed. If the resistance is low the valve 43 remains in the position shown so that fluid passes from the pipe 15 into the pipe 45 where it joins fluid leaving the outlet 26 and is pumped through the control valve 18 into the cylinder side 10b to provide a high speed advance of the prop. The manual pump, Fig. 3 (not shown) for supplying fluid to the jack 3 is mounted within the reservoir 19 and comprises a piston 22 reciprocable in a cylinder 21 by a crank 23 secured to a boss 20 having a bore 20a for receiving an operating lever arranged to open an exhaust valve 33 which connects the reservoir 19 to atmosphere.
