Abstract: 1,175,281. Distillation apparatus, multistage flash type. DRYSDALE & CO. Ltd. 4 July, 1968 [4 July, 1967], No. 30636/67. Heading BIB. Liquid to be distilled, e.g. salt water, flows through pipe 18 into the lowest of a series of superposed chambers 3 to 9 connected by standpipes 3A to 8A, progressive reduced pressure being maintained in successive chambers by vacuum pump 20 connected to the highest chamber 9; the liquid undergoes successive partial evaporation as it rises through the chambers, and the residual liquid flows out of chamber 9 through downcomer pipe 10 into a sealing tank 11 which discharges at atmospheric pressure. No liquid pump is necessary because the minimum height of the highest chamber above the lowest chamber and the minimum length of the downcomer pipe are each at least equal to the height of a barometric column of the liquid corresponding to the degree of vacuum in the highest chamber. The vapours evolved in each chamber condense on tubes 14, and the condensate flows up duct 13 and is discharged through pipe 15 to sealing tank 16.

Title: Improvements in the manufacture of tertiary alkylaryloxy alkylols
IPC: C07C305/10
Filed: 1935-11-08
Abstract: Ether-alcohols of the formula A--R--O--R<1> wherein R represents an aromatic ring, A represents a tertiary alkyl radical having at least 8 carbon atoms, and R<1> represents a monohydroxy or dihydroxy alkyl radical are made by condensing a p  phenol of the formula A--R--OH with an alkylene oxide or alkylene halohydrin in the presence of an alkali.  Sulphuric esters of the above ether-alcohols are made by treating solutions of them with sulphuric acid at low temperatures. Alkalis specified are alkali metal hydroxides or carbonates when using alkylene oxides such as ethylene, propylene and isobutylene oxides; when using alkylene halohydrins such as ethylene, propylene, glycerol or isobutylene chlorhydrins, the phenols are preferably used in the form of alkali metal phenates.  The use of solvents such as alcohol, toluol, butanol, or acetone at moderate temperatures (50--125 DEG  C.) is preferred.  The alkyl-phenols are made by condensation of tertiary olefines, such as dibutenes, di-, tri-, and tetra-polymers of isobutylene, isoamylene, hexylene, heptene, octene, with phenols, cresols, naphthols, xylenols, guaiacol and similar phenols as described in Specifications 409,111 and 440,910.  The ether-alcohols are used as lubricants for textiles or fine mechanisms such as watches, as plasticizers for synthetic resins and coating compositions comprising oleoresinous varnishes or cellulose esters or ethers, and, sulphated or not, they may be added to insecticides, cosmetics, soaps, tanning material or dyestuffs to assist dispersion. By sulphation, they become wetting, emulsifying, or detergent materials.  In examples, ethylene oxide is condensed in presence of sodium hydroxide in alcohol solution with (1) a .a .g .g -tetramethylbutylphenol, (2) ter-iso-dodecylphenol (obtained by condensation of tri-isobutylene and phenol), (3) ter-isooctylphenol (obtained from phenol and the dibutene fraction, of p.p. 106--116, obtained by copolymerization of the three isomeric butenes as described in Specification 440,910) but using potassium hydroxide. Also, ethylene chlorhydrin is condensed with the sodium salts of (4) a .a .g .g -tetramethylbutylphenol or its monochlor derivative, (5) ter - isohexadecylphenol (from phenol and tetraisobutylene). a .a .g .g -Tetramethylbutylphenol is condensed with (6) propylene oxide, (7) isobutylene oxide, and (8) glycerol monochlorhydrin.ALSO:Emulsifying-agents are made by sulphation of ether alcohols of the formula A--R--O--R<1>, wherein R represents an aromatic ring, A represents a tertiary alkyl group of at least 8 carbon atoms, and R<1> represents a mono- or di-hydroxy alkyl radical.

Abstract: 1,081,585. Semi-conductor circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 12, 1966 [July 20, 1965], No. 30904/65. Heading H3T. [Also in Division H2] The current supplied to a load (1) through a circuit (2) including a thyristor is regulated in dependence on the temperature of the thyristor. A voltage proportional to the temperature of the thyristor junction is produced by an analogue device (6) and compared with a reference voltage to obtain a difference signal which controls the phase of the thyristor firing pulses. A suitable analogue device (Fig. 2, not shown) comprises a diode carrying a current proportional to the thyristor current and mounted on the same heat sink as the thyristor in a housing designed to give the diode thermal characteristics similar to the thyristor. Alternatively the analogue may be a circuit with an input current-output voltage characteristic corresponding to the mathematical relationship between the current through the thyristor and the temperature of its junctions. Excessive thyristor temperature operates a circuit breaker (3).
