Title: Improved plasticizer alcohols and esters
IPC: C07C29/16
Filed: 1956-02-22
Abstract: Alcohols are prepared by reacting an olefinic feed with carbon monoxide and hydrogen at elevated temperatures and pressures in the presence of a cobalt carbonylation catalyst to form an aldehydic reaction product which is hydrogenated to produce alcohols, the olefine feed being obtained by subjecting a petroleum fraction to a steam cracking treatment, separating from the steam-cracked product a naphtha fraction containing olefines with 6 to 8 carbon atoms per molecule together with di-olefines and tertiary olefines, polymerizing substantially all the diolefines and tertiary olefines of said naphtha fraction by the action of aluminium chloride or aluminium bromide as catalyst and separating by distillation the polymers so formed from the distillate which contains olefines with 6 to 8 carbon atoms per molecule.  The tertiary olefines referred to are defined as those of formula RR1C=CH2 in which R and R1 are monovalent hydrocarbon radicals.  The treatment with aluminium chloride may be carried out batchwise or continuously.  In the example naphtha and higher boiling petroleum stocks are cracked at 538-816 DEG  C. and 1-10 atmos. with steam or inert gas as diluent; a product boiling in the range 5-120 DEG  C. and containing aliphatic olefines and diolefines, cyclo-, mono- and diolefines in addition to paraffins and aromatic compounds; the fraction is treated in a thermal soaker to dimerize selectively the cyclic dienes; the mixture of dimerized cyclic diolefines and unreacted hydrocarbons is distilled and a fraction containing aromatic hydrocarbons and C5-C8 olefines is separated; aluminium chloride is added to this fraction and the polymerization is stopped after 0.25 to 2 hours by the addition of a polar substance, such as water or alcohol, and a washing agent; the product is distilled and the overhead product, consisting essentially of mono-olefins, from which most of the Type III olefines have been removed, and of aromatics, is fractionated and an olefine fraction boiling in the range 57-71 DEG  C. is separated; this fraction is mixed with cobalt naphthenate or oleate and treated with a mixture of hydrogen and carbon monoxide at elevated temperature and pressure; the liquid carbonylation product containing cobalt carbonyl in addition to the desired heptyl aldehydes is decobalted by heating under pressure and stripping with water, steam or hydrogen; the liquid aldehyde product is hydrogenated in the presence of a hydrogenation catalyst such as nickel, copper chromite or tungsten, nickel or molybdenum sulphide to give heptyl alcohol. The heptyl alcohol may be esterified by treating with an acid or anhydride, such as phthalic anhydride.  The process is carried out similarly with fractions yielding octyl and nonyl alcohols which are converted to their phthalates.

Title: Improvements in and relating to overload steam turbines
IPC: F01K9/00
Filed: 1932-02-24
Abstract: 378,803. Turbines. BROWN, E., 8, Bahnhofweg, Baden, Switzerland. Feb. 24, 1932, No. 5498. [Class 110 (iii).] To reduce friction and ventilation losses in the overload low-pressure sections 5 of a steam turbine which are run in parallel with one or more normal load low pressure sections 3 in series with high pressure sections 1, 2 when running idle with the valve 6 closed, the condenser, preferably a surface condenser, at least during non-operation of the overload low pressure sections, is subdivided into a primary condenser 8, into which the normal load sections 3 exhaust, and a secondary condenser 9, with which the overload sections 5 are in sole connection and in which, by specifically low heat loading or by supply of cooling water at lower temperature than that supplied to the primary condenser, a higher vacuum is formed and maintained. The secondary condenser 9 may be wholly or partly cooled by cold make-up water from cooling towers. When the overload sections 5 are not operating, the cooling water pumps of the secondary condenser 9 are partly or wholly supplanted by those of the primary condenser 8, cooling water being diverted from the latter through the connection 15, the valve 18 being closed. The air extractors of the secondary condenser 9 during normal load running deliver to an intermediate vacuum, preferably to that in the primary condenser or in the connection of the latter with its air extractor or in an intermediate stage of the extractors of the primary condenser 8. Cooling steam from the secondary condenser 9, or from a main low pressure exhaust, or a stage of the normal load low pressure sections, is circulated, preferably by the fan action of the blading, through the non-operative L.P. sections and over the cooling surfaces of the condenser to remove the heat generated by the idle running rotors. The initial volume of the cooling steam is proportioned to the blade areas of the idle overload low pressure section that the kinetic energy derived from the heat drop between the primary and secondary condensers, or between an operative low pressure stage and the secondary condenser, as to eliminate a part or the whole of the ventilation &c. losses.

In a switch having an are horn 16 and a magnetic blow-out coil 13 connected to a fixed contact 22 and a second arc horn 17 associated with a main moving contact 23, an auxiliary movable contact 29 remains electrically connected with the horn 17 when the contact 23 is in the closed position and during its opening movement until the arc is extinguished, the contact 29 then being disconnected by, and during the final movement of, the main moving contact 23. The auxiliary contact 29 co-operates with a fixed contact clip 18 and is pivoted on a member 27 fixed on the moving contact arm 24. When the switch is opened, the contact 29 slides downwardly in the clip 18 so that by the time the contact arm 24 abuts a stop 30 on the contact 29, the contact 29 has been moved to a position in which it is clear of a fixed stop 33. From this position the contact 29 is pivoted away by the moving arm. When the switch is closed, the arm 24 and the contact 29 move together until the contact 29 engages in the clip 18 and abuts a fixed stop 32, the further movement of the arm 24 then resulting in the contact 29 being thrust up between the stops 32, 33. As shown, a blow coil 35 may be connected between the horn 17 and the contact clip 18. An auxiliary moving contact 29 may be provided on both sides of the contact arm 24. Figs. 6 and 7 (not shown) illustrate an arrangement in which a bellows is mounted between the contact arm 24 and the auxiliary contact 29, the bellows providing an air-blast during the opening period in which relative motion occurs between the arm 24 and contact 29.
