Title: Manufacture of octahydrophenanthrene-2-carboxylic acids and esters thereof
IPC: C07C51/367
Filed: 1948-04-14
Abstract: Sterically homogeneous octahydrophenanthrene-2-carboxylic acids and esters are manufactured by reacting a sterically homogeneous 1-keto-octahydrophenanthrene, containing in the 2-position a hydrocarbon radical and an esterified carboxyl group and in the 7-position a phenolic hydroxy group or a substituent convertible thereto, with an organo-metallic compound in order to introduce a hydrocarbon radical into the 1-position, directly or indirectly eliminating the resulting tertiary hydroxy group, separating the two isomers so obtained by fractional crystallization, chromatography or sublimation, and, if desired, converting the esterified carboxyl group in the 2-position into a free carboxyl group, or the substituent in the 7-position into a free hydroxy group, or both, in either order, and hydrogenating non-aromatic carbon-to-carbon multiple bonds at any desired stage after reaction with the organo-metallic compound.  The starting material may be an individual racemate (obtainable by fractional crystallization, chromatography or sublimation) or an individual optically active antipode, the initial reaction product being (on account of the introduction of an additional asymmetrical carbon atom) respectively a mixture of two racemates or of two optically active antipodes, the relative proportions of which may be influenced by the reaction conditions. The other steps in the process may be carried out as described in Specification 591,994, and the various substituents present in the starting materials may be as therein enumerated.  Free carboxylic and hydroxy groups in the products may be subjected to further transformations as described in the said Specification and in Specifications 622,892 and 629,118.  Examples illustrate various features of the invention, using various isomers of 7-methoxy-1-keto-2-methyl-1 : 2 : 3 : 4 : 9 : 10 : 11 : 12-octahydrophenanthrene-2-carboxylic acid methyl ester as starting materials, and further conversions of certain of the products of the examples are described in detail.

Patent GB-591078-A (GB)
Title: Process relating to the production and recovery of hydroaromatic cycloparaffin hydrocarbons
IPC: C07C13/00
Filed: 1945-04-26
Abstract: Naphthenic hydrocarbon mixtures such as gasolines comprising hydroaromatic and non-hydroaromatic cycloparaffins and open chain paraffins are distilled to separate a lower boiling fraction containing most of the non-hydroaromatic, and a higher boiling fraction containing most of the hydroaromatic and the paraffin hydrocarbons, the latter fraction is subjected to an isomerization to isomerize hydroaromatics to non-hydroaromatics which are separated, added to the lower boiling fraction containing non-hydroaromatics, and the mixture subjected to isomerization to isomerize non-hydroaromatics to hydroaromatics which are separated.  A straight run gasoline may be fractionated to obtain a methylcyclopentane, cyclohexane fraction of B.R. about 65-85 DEG  C. or wider.  This is fractionated to separate a methylcyclopentane fraction, for example of B.R. 65-75 DEG  C., and a cyclohexane fraction, for example of B.R. 75-85 DEG  C.  The former is treated with a Friedel Crafts' type catalyst such as aluminium halide at about 20-100, preferably 50-90 DEG  C.  A preformed aluminium chloride, hydrocarbon complex at about 65-85 DEG  C. is preferred.  Hydrogen halide promoter equal to 0.1-3 per cent of the weight of hydrocarbon is present.  The product is fractionated to recover cyclohexane while unconverted methylcyclopentane is recycled at least in part.  The initial cyclohexane fraction is treated similarly but at temperatures of about 110-200 DEG  C., particularly with aluminium chloride, hydrocarbon complex at about 140-150 DEG  C., whereby cyclohexane is isomerized to methylcyclopentane while dimethylpentanes are converted to higher boiling materials.  Instead of metal halide catalysts, sulphides of Group 6 metals, especially molybdenum and tungsten may be used at about 300 DEG  to 600 DEG  C. and a hydrogen pressure of, say, 50-200 atm.  The product is fractionated to give relatively pure methyl-cyclopentane which is passed to the first isomerization stage. Unconverted cyclohexane is recycled.  The separation of hydroaromatic hydrocarbons such as methylcyclohexane from C7 gasoline fractions is effected similarly.

Title: Improvements in or relating to heavy hydrocarbon cracking apparatus for internal-combustion engines
IPC: F02M27/02
Filed: 1937-04-14
Abstract: 482,639. Vaporizers for internalcombustion engines. SOC. INDUSTRIELLE HELLENIQUE DES GAZOFACTEURS BERHOUDAR SOC. ANON. April 14, 1937, No. 10638. Convention date, July 25, 1936. [Class 7 (iii)] [Also in Group XII] In the production of oil gas for internalcombustion engines by cracking heavy hydrocarbons in a vessel surrounded by a heating chamber, the combustion products from the latter are exhausted by means of a reduced pressure which is the more reduced as the engine speed is increased. This control of the draught may be effected by discharging the gases into the engine exhaust pipe or into a pipe connected to a suction pump which is driven by the engine. In the former embodiment of the invention, the motive gases are fed to the suction pipe 50, Fig. 4, of the engine from a cracking vessel A, Fig. 1, through a withdrawal pipe 20, the gases from the heating chamber B being fed to the exhaust pipe 22 through a pipe 21 provided with a Venturi tube 23. The cracking vessel A comprises a closed tube 10 with an open-ended multi-walled tube 11 arranged concentrically therein and heavy hydrocarbon is fed to the surfaces of the latter by a Venturi tube 6 connected to a controlled oil reservoir 2. The vessel may be constructed of a catalytic material, such as nickel. The heating chamber B, which is lined for the most part by refractory material 8, is charged with charcoal and is provided with a liquid fuel feeding device consisting of a constant level petrol or oil reservoir 14, igniter 12 and an injector tube 17. In operation, the engine is started by the ordinary carburetter and the charcoal is then ignited by a petrol flame from the injector tube 17. Heavy hydrocarbon, identical with that fed to the cracking vessel, is then supplied from the reservoir 14 to the incandescent charcoal to maintain the heating. Additional air cocks 9 may be provided to ensure complete combustion. A cock 5 on the cracking vessel allows air, steam or drops of water to be admitted for combustion of the cracking residues. After passage through a tar filter and a device for mixing with air, the combustible mixture flows through a condensing filter consisting of an eccentrically arranged inlet pipe 40, Fig. 4, and an inverted cone 42 to separate condensate, followed by a filter 43 of metal gauze.

Title: Improvements in or relating to valve closing mechanisms of refrigerating plants
IPC: F25B41/06
Filed: 1928-04-12
Abstract: 310,637. Shrode, J. L. April 12, 1928. Thermostats; electrically-actuated valves.-The thermostatically-controlled expansion valve 8 of a refrigerating-machine is positively closed when the machine stops by means comprising a system of connected levers which, during the working of the machine, is kept out of action by the motive power in the working circuit. In normal operation, the valve is merely pressed against its seating by a spring 17 and is opened more or less by a thermostatically controlled diaphragm 3 to regulate the passage of the refrigerant from a chamber 12 communicating with the cooling coils to an outlet (not shown) in the bore 13 leading to the expansion coils, the diaphragm 3 acting through a push-rod 11 and being itself actuated by the varying pressure of gas in a chamber 6 communicating through a tube 60 with a thermal chamber, the temperature of the walls of which is regulated by the returning refrigerant. Below the valve 8 is a push-rod 19 pressed downwards by a spring 38 on to an adjustable screw-stop 22 carried by a lever 21. The lever 21 is coupled to the short arm of a lever 24 fulcrummed within a casing 20 on a pivot 25 and coupled to the core 34 of an electromagnet 33 mounted in a housing 32. The electromagnet is normally excited by connection through conductors 36 to the working circuit of the machine so that the core is drawn up and the rod 19 is allowed to fall away from the valve. When the machine shuts down, the core falls, being cushioned by a buffer 37 of rubber, cork, felt &c., its weight, with that of the lever 24, raising the rod 19 to force the valve on to its seating. This action is assisted by a spring 29 located around the stop 22 and seated on an adjustable plug 30 in the casing. A bore 31 in the plug 30 enables the screw stop 22 to be adjusted.
