Abstract: 741,171. Hydraulic intensifiers. HYDROPRESS, Inc. June 27, 1951 [June 27, 1950], No. 15240/51. Class 69 (2). A hydraulic intensifier comprises at least a pair of successively operating intensifier units 11A, 11B and control means operative to precompress the fluid in one of the intensifier units to a pressure equal to that in the highpressure system before the piston of the other intensifier unit has reached the end of its pressure stroke, the units being supplied with pressure from a main pump 28 during the pressure stroke and from an auxiliary pump 29 of smaller capacity during the return stroke as well as during that part of the pressure stroke in which precompression takes place, one or both pumps having automatic pressure control, the successive admission of pressure being controlled by valve means operated in relation to the stroke of the intensifier pistons. The valve means comprises a main change over valve 32 which alternately connects the pump 28 to one of the secondary control valves 37A, 37B and the pump 29 to the other, under the control of piston actuated switches 23A, 23B. When the pump 29 is connected to the valve 37B and the pump 28 to the valve 37A, the valve 37B is initially in by-pass condition while valve 37A connects the pump 28 to operate the unit 11A. Actuation of switch 22A by the unit 11A moves the valve 37B to connect the pump 29 to operate the unit 11B. Actuation of the switch 23A by the unit 11A moves the main valve 32 to connect the pump 29 to the valve 37A and the pump 28 to the valve 37B to operate the unit 11B, and after a time delay moves the valve 37A to connect the pump 29 to the return cylinder of the unit 11A which at the end of its stroke actuates the switch 21A to move the valve 37A into bypass condition and the operation of the other half of the cycle is similar to the first half described.

Title: An improved process for removing mercaptans from hydrocarbons by alkali treatment inpresence of solubility promoters
IPC: C10G19/04
Filed: 1942-10-30
Abstract: 570,863. Removing mercaptans from hydrocarbons. SHELL DEVELOPMENT CO. Oct. 30, 1942, No. 15251. Convention date, Sept. 2, 1941. [Class 91] In the process of removing mercaptans from hydrocarbons containing gum-forming components by extraction with an alkali metal hydroxide in the presence of a solubility promoter for mercaptans, the formation of coloured bodies and of gumming or resinous emulsifiers is prevented or minimised by carrying out the process in the absence of free oxygen and of gums or other oxidation products such as peroxides. aldehydes, ketones, peraldehydes, acids, peracids, &c. This is effected either by preventing free oxygen from entering the system or by removing it after it has entered, e.g. by carrying out the process immediately after distillation of the hydrocarbons, using storage tanks with floating roofs, liquid seals, blankets of inert gas, and superatmospheric pressure. Also by passing the feed over oxygen absorbing substances such as alkali metals, phosphorous, alkaline solutions of cuprous oxide, sodium pyrogallol. &c., or, if gum has already formed over absorbents such as clays, silica gel, bauxite, or activated carbon. If necessary the hydrocarbon may be redistilled. The aqueous alkali solution is also de-aerated.

Abstract: 331,640. Sautter, W. May 16, 1929. Direct liquid-pressure apparatus.-In apparatus for delivering inflammable &c. liquids from one or more containers C by water admitted by a pipe 21, the liquid being delivered through a pipe 23, a space 16 is arranged between the water admission valve 13 and the inlet 8 or 9 to the pipe 21, so that, when the valve 13 is closed and the apparatus is not delivering, this space is connected to low pressure, such as atmosphere, by a channel 15, thus allowing leakage past the valve 13 to escape without affecting the liquid in the container C. When the valve 13 is opened by the lever 1 for a delivery of the petrol &c. a valve 14 carried by the valve 13 closes the channel 15, so that the water passes through a non-return valve 18 and passage 19 to the inlet 8 or 9 of the water pipe 21. In another form, a non-return valve cuts off the low-pressure space from atmosphere when the water inlet valve is opened, and a spring opens it when the water valve closes. A float 32 carrying a disc 32<1> which lies between the two liquids is guided by the pipe 21 and a rod 24, and closes the ends 49, 52 of the pipes 23, 21 in its top and bottom positions.
