Abstract: 250,232. Akt.-Ges. Brown, Boveri, et Cie. April 6, 1925, [Convention date]. Regulating or controlling.-The no-load losses of a compressor are reduced by connecting a vacuum pump to the delivery side of the compressor while it is disconnected from the pressure pipe, the suction pipe being closed, so that the compressor itself causes an increase in the vacuum from the delivery to the suction side. Fig. 1 shows a compressor in which a high-pressure stage compressor 2 is used intermittently, being shut down by a stop valve 7 and a non- return valve 9 which closes the high-pressure delivery pipe 8. By means of a pipe 10 and valve 11, Fig. 2, the delivery side of the compressor 2 is opened first to atmosphere or to the suction side of the low-pressure stage 1 as shown in dotted lines, then to a vacuum tank 14, and finally to a vacuum pump 15, which at this point acts only on the compressor 2 but during the rest of the working acts on the vacuum tank 14. The pump, which may be of the piston, rotary, or ejector type, is stopped when the highest possible vacuum in the tank 14 has been obtained.
Patent GB-466980-A (GB)
Title: Processes for refining hydrocarbon oils
IPC: C10G21/20
Filed: 1936-03-23
Abstract: Hydrocarbon oils are refined by countercurrent or batch treatment with one or more of the following solvents: allylamine, phenylnaphthylamine, diphenyl-ethylene diamine, benzyl-aniline, propionamide, p-amido-diphenyl, allyl cyanide, m-nitro-benzaldehyde, p-nitrodiphenyl ether, o-nitro-diphenyl, quinoline, butyramide, o-nitraniline, o-anisidine.  The selective solvents may be mixed with auxiliary solvents of the following types: (A) those soluble preferably in the selective solvent and also soluble in the oil treated; examples are aromatic and hydroaromatic hydrocarbons (other than polycyclic aromatic hydrocarbons) and non-selective aliphatic and aromatic halogen derivatives such as chlorinated hydrocarbons; they increase the solvent power and so the amount of extract, leaving a more refined oil; (B) those miscible with the selective solvent but not or only slightly with the oil; examples are alcohols and organic acids; they decrease the solvent power and so the amount of extract, which is desirable when treating naphthene-base oils; (C) those miscible with the oil only; examples are propane, butane, or other low-boiling paraffins; they sharpen the selective power. Dewaxing, before or after extraction, may be effected by chilling and centrifuging, filtering, or decanting, using as diluent a mixture of such proportions of selective solvent and auxiliary solvent of type A or C that the solvents do not separate from each other on chilling. The slack wax may be refined by treatment with the same or a different solvent mixture.  Recovery of the solvents from the raffinate, extract, wax, or dewaxed oil is effected by distillation or by extraction with solvents not dissolving the oils or wax.  In examples, a dewaxed oil is batch-extracted at 40 DEG  F. with 1, 0,5, and 0,5 vol. respectively of quinoline or a blend of 80 litres of quinoline with 20 litres of ethyl alcohol.

Abstract: 1278903 Turbochargers for I.C. engines; centrifugal blowers; gas turbines CATERPILLAR TRACTOR CO 23 Feb 1970 [21 March 1969] 8623/70 Headings F1B F1C F1G and FIT A turbocharger assembly for an I.C, engine comprises a turbine rotor 14 contained within a vaneless housing 17 divided by an annular partition 18 into two annular compartments 19, 20. A flapper valve 24 is mounted at the inlet to the housing 17 such that when the flow of I.C. engine exhaust gases through manifold 12 falls-off at low engine speeds the valve 24 can be manually or automatically moved to the position 24' to shutoff compartment 19 and thus direct all the exhaust gases to compartment 20 so as to maintain the turbine speed and the output of the compressor 16 driven thereby. For automatic operation the valve actuating mechanism comprises a piston 30 slidable in a cylinder 31 and connected to the valve 24 by a rod 28 and lever 26. The righthand side of piston 30 is subjected via pipe 34 to the air-pressure in the engine intake manifold or at the compressor outlet 16. When this pressure falls-off spring 32 urges piston 30 to the position 30' thus moving valve 24 to the position 24' to shut-off compartment 19. In the arrangement shown valve 24 is pivoted at 25 in a rectangular cross-section connecting duct 13. However the latter may be of circular crosssection, Fig.3 (not shown). In further modifications, Figs.5, 6 (not shown), the connecting duct 13 is omitted and the valve is pivoted within the engine exhaust manifold. The latter may include a partition (40), Fig.4 (not shown), in alignment with the normal position of the valve and dividing the manifold into two portions (41, 42) each in communication with two exhaust ports of a four cylinder engine.
