Title: Improvements in or relating to hydraulic accumulator systems
IPC: F15B1/24
Filed: 1942-07-22
Abstract: 559,648. Hydraulic accumulators. VICKERSARMSTRONGS, Ltd., and WARDLE, J. July 22, 1942, No. 10261. [Class 69 (ii)] Relates to a hydraulic accumulator system in which a continuously-running pump 6 supplies an accumulator 1 through valves 9, 15 and a pressure line 16 and the piston 17 of the accumulator, which operates against a gaseous loading medium in the space above it, is adapted at the end of its upward travel to actuate the differential piston 2a of a servomotor so that fluid pressure then operates the valve 9 to the right so as to byepass the liquid from the upper (discharge) side of the pump 6 and return it to the lower (suction) side. According to the invention, the larger diameter of the piston 2a is disposed uppermost and the upper end of the cylinder 3 is connected either with the pump pressure through a connection 14 or with the gaseous loading medium through a passage passing through the centre of the piston 2a Figs 6, 7 (not shown). In the position shown, a circumferential groove 4 in the piston 2a connects the suction side of the pump 6 to the cylinder 8 of the valve 9. When the piston 2a is raised, the line 18 leading to the cylinder 8 is put into connection with the pressure side of the pump through the connection 14 and a passage through the piston 2a so that the valve 9 is moved to the right and the pump operates idly. The original condition is restored when the piston 17 descends. In other modifications a separate connection leads from the pressure line 16 to the side of the cylinder 3 and thence to a groove in the side of the piston 2a which, in the upper position of the piston, connects with the line 18.

Patent GB-459595-A (GB)
Title: Improvements relating to the refining of hydrocarbon liquids
IPC: C10G21/10
Filed: 1935-04-09
Abstract: Aromatic extracts obtained by treating a petroleum distillate with a solvent such as sulphur dioxide, are concentrated or freed from non-aromatic hydrocarbons by treating with a paraffinic solvent in the presence of liquid sulphur dioxide.  The paraffinic solvent used is substantially insoluble in liquid sulphur dioxide and in the aromatic part of the extract, and is preferably of higher boiling point than the extract.  Suitable paraffinic solvents are aromatic-free petroleum distillates such as spindle oil, or lubricating oil.  Aromatic extracts of kerosene or petroleum fractions boiling at 60 to 150 DEG  C., obtained by extraction, for example, with sulphur dioxide or with aqueous phenol as described in Specification 273,351, [Class 91], are treated.  When the solvent used in the extraction is not sulphur dioxide, the solvent should be removed before treating the extract.  Example: a heavy lubricating oil, a dewaxing filtrate, or a transformer oil is mixed with an aromatic extract from kerosene, and the mixture extracted with two lots of sulphur dioxide.  The raffinate after treatment with acid and a bleaching earth and distilling forms a refined kerosene and a residual lubricating oil.  The extracts are combined, freed from sulphur dioxide, and fractionated to form a motor fuel or a motor fuel component.  The raffinate, if desired, may be returned to the extraction process.  Extraction may be effected in countercurrent or in a series of mixing and separating vessels or in washing towers as described in Specification 321,200, [Class 91].

[Class 100 (i)] In a selvedge guide as described in the parent Specification, the members which are engaged by the selvedge and serve to adjust the angular position of the guiding roller, comprise bars 19, 20, Figs. 1 and 2, which, in projection on a plane at right-angles to that of the fabric, first diverge, then converge, cross and again diverge, and, in projection on the plane of the fabric, diverge from their point of attachment to the swinging frame 2 carrying the guiding rollers 4, 6. The roller 6 may be slightly barrel shaped so that the fabric is gripped between the rollers 4, 6 at a point instead of along a line, and the position of this point along the rollers may be varied by adjusting the angular position of the axis of the roller 6 relatively to that of the roller 4. For this purpose, the arm 5 carrying the roller 6 is pivoted on a sleeve 13a mounted on a slightly cranked pin 13 carried by the frame 2. Angular adjustment of the pin 13 causes an angular displacement of the axis of the roller 6. The swinging movement of the frame 2. about its pivot 3 may be controlled by a brake which may comprise a bellows, the end plates of which are connected to the fixed frame 1 and the counterweight 7 of the frame 2, an air valve being provided for adjustment of the braking effect. The guiding devices at the two selvedges may in certain circumstances be so spaced apart that the selvedges are normally at the position of extreme penetration between the bars 19, 20, the central portion of the web being slack.
