Title: Cylindrical steam distributor for direct action pumps
IPC: F01L25/06
Filed: 1924-04-29
Abstract: 216,847. Bronda, B. May 31, 1923, [Convention date]. Fluid-actuated gears. - A steam pump is provided with a fluid-actuated valve comprising solid heads 1, 2 which control a central admission 4, perforated heads 9, 10 controlling exhaust ports 13, 14, and ported extensions 15, 16 upon which fluids act to effect the initial movement of the valve. The main passages 7, 8 are connected to annular admission and exhaust ports 5, 6 in the valve chest. The extensions 15, 16 have auxiliary passages 19, 20 connecting the valve ends with annular recesses 17, 18 in the body of the valve. Crossed auxiliary passages 29, 30 connect the cylinder with the valve-chest ends. The valve is locked in its end position, and its final movements are cushioned. In operation, when the piston 31 moving to the left uncovers passage 29, the valve is thrown to the left. When the head 2 uncovers the right-hand annular port of passage 8 in its motion, the right-hand ends of the valve-chest are. opened to the main cylinder the pressure fluid in which acting on the head 2 completes the movement of the valve thus opening port. 14 and passing to exhaust meanwhile holding the valve in its reversed position. When either of the ports 13, 14 is opened, the end of the valve communicating with the end of the main cylinder put to exhaust is not immediately affected owing to the bore and length of the passages 27, 28. The throttled fluid thereby cushions the valve. In a modification, the passages 27, 28 are connected to the maincylinder ends, and the passages 7, 8 enter the main cylinder at some distance from the ends and have non-return valve-controlled branches leading to the cylinder ends. When the main piston passes the passages 7, 8, the exhaust is cut-off and the consequent compression effects the initial movement of the valve.

Title: Process for the production and recovery of hydroaromatic cycloparaffin hydrocarbons
IPC: C07C5/29
Filed: 1945-04-27
Abstract: Hydroaromatic cycloparaffins are obtained by distilling a naphthenic hydrocarbon mixture of gasoline boiling range which contains hydroaromatic and non-hydroaromatic cycloparaffins, and open chain paraffins, to separate an intermediate fraction containing hydroaromatic cycloparaffins mixed with the non-hydroaromatic having the same number of carbon atoms, and a lower boiling fraction, contacting said intermediate fraction with an isomerization catalyst comprising a liquid aluminium halide-organic compound complex at a temperature of 30-140 DEG  C. so that the non-hydroaromatic cycloparaffins are isomerized to hydroaromatic and the latter are selectively dissolved in the catalyst, and scrubbing the resulting solution with a hydrocarbon liquid readily separable from the hydroaromatic hydrocarbons by distillation, for example the said lower boiling fraction.  The intermediate fraction may be a C6 fraction containing hexanes, cyclohexane, and methylcyclopentane, although C6-7, C7 or higher fractions may be used.  It is introduced at an intermediate point of a packed column down which is passed a liquid complex of aluminium halide and, for example, aromatic, paraffinic, olefinic, cycloolefinic or mixed hydrocarbons such as an aromatic kerosene extract, phenols, acids or ethers. Temperature is preferably 70-100 DEG  C. while pressure is sufficient to liquefy the hydrocarbons.  Hydrogen halide is introduced to maintain a concentration of about 0.1-2 per cent by weight of the hydrocarbons. An extract phase comprising complex and cycloparaffins forms in the bottom of the column and is passed to the top of a scrubber fed at the base with the lower boiling fraction separated from the original feed, for example, a pentane and/or butane fraction, and maintained at similar temperature and pressure.  Complex free of cycloparaffins settles and is recycled to the extraction column.  The overhead hydrocarbons are fractionated, the light fraction being recycled to the scrubber, methylcyclopentane to the extractor, and cyclohexane recovered as product.  The light fraction, and the raffinate phase from the extractor are first stripped of hydrogen halide.  Where the initial charge contains aromatics, these remain in the complex after the scrubbing and are recovered by distillation or stripping with gases.  Examples describe the isomerization and extraction of methylcyclopentane fractions to obtain cyclohexane and the treatment of an aluminium chloride-hydrocarbon complex extract phase to recover aromatics and cycloparaffins separately.
