Patent GB-589821-A (GB)
Title: Improvements relating to the production of phenolic ethers of glycerol
Filed: 1944-10-27
Abstract: Mono-phenolic glyceryl ethers are prepared by condensing phenol, a cresol or a mixture of these, such as cresylic acid, with glycerol in the presence of a condensation catalyst, the phenolic reagent being in molecular excess of the glycerol, and the reaction being concluded while the product contains a predominating proportion by weight of the mono-ether relative to the di-ether.  The reaction product may be treated with a hydrocarbon solvent for the ether and unreacted phenol boiling at 80-150 DEG  C., and an aqueous solvent for the unreacted glycerol, polyglycerols formed as a bye-product, and catalyst, the resultant mixture stratifying into two layers.  The hydrocarbon layer is distilled to obtain the ethers, and the aqueous layer concentrated and returned to the process.  Suitable catalysts are alkali metal acetates and other salts of lower fatty acids.  The excess of phenolic reagent is generally about 40-100 per cent. Condensation is preferably conducted at boiling temperature gradually rising to not above 250 DEG  C., water being removed continuously with phenol as entrainer.  Pressure may be super-atmospheric.  In the examples, a meta-para-cresol mixture is condensed with 88 or 42 per cent molar excess of glycerol in the presence of sodium acetate.  Water and xylene are added and the xylene layer distilled, to recover xylene and unreacted cresol, and to separate the mono-ether from the minor proportion of di-ether.

Title: Improvements in the separation of hydrocarbon mixtures by fractional distillation
IPC: C07C7/08
Filed: 1928-07-20
Abstract: 324,350. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 20, 1928. Acyclic hydrocarbons; cyclic hydrocarbons.- Mixtures of hydrocarbons having closely adjacent boiling points and different degrees of saturation are separated into their constituents by fractional distillation under normal, increased, or reduced pressure with the addition, prior to or during the distillation, of one or more of the following organic solvents :- ethylene chlorhydrin, glycol monacetate or diacetate, glycol monomethyl ether, glycerin di- or tri-acetate, lactic acid nitrile, diethyl tartrate, furfurol, or aromatic bases such as aniline, toluidine, or phenyl hydrazine. The addition of one of these substances causes the more saturated hydrocarbons to distil over first. The process may be applied to substances normally liquid and also to those liquefiable under pressure. In an example a mixture of cyclohexane and benzene is mixed with ethylene chlorydrin and distilled; practically pure cyclohexane distils off, leaving the benzene in solution in the ethylene chlorhydrin. In another example a mixture containing butadiene and alpha-butylene is mixed with ethylene chlorhydrin and distilled under pressure; the first fraction is mainly alpha-butylene, followed by 98 per cent of butadiene. Specifications 302,203, [Class 8 (ii), Air and gases. Treating &c.], and 319,025 are referred to.

Patent GB-1153902-A (GB)
Title: Improvements in or relating to Electromagnetic Circuit Devices
Inventor: WANLASS LESLIE KENT
IPC: H01F29/14
Filed: 1966-05-13
Abstract: 1,153,902. Frequency changing. L. K. WANLASS. 13 May, 1966, No. 21411/66. Heading H2F. [Also in Divisions H1 and H3] A magnetic device which may be a variable inductor (which forms the subject of Specification 1,153,901, is disclaimed in the present Specification), transformer, auto-transformer frequency doubling transformer, magnetic amplifier inverter, rectifier or modulator has a magnetic core having a first portion 17 (Fig. 3), carrying a direct (or low frequency modulating) current winding 20 used (except in an amplifier or inverter embodiment) for control purposes and a second portion 18 carrying an A.C. (input) winding 19. The core portions 17 and 18 are interconnected by four magnetic zones or legs 13, 14, 15, 16 (Fig. 3A) and in each half cycle of current in winding 19 the A.C. and D.C. fluxes produced by the currents in 19 and 20 are additive in one pair of diagonally opposite legs and in opposition in the other pair (14, and 16 as shown). The overall effect is to reduce the self inductance of winding 19 with increase of control D.C. in winding 20. As the control current is increased to a substantial value the reluctance of the legs in which the A.C. and D.C. fluxes are additive in a particular half cycle becomes high and increasing flux therefore crosses the core portion 17 diagonally (as shown) linking with a secondary winding 21 if provided. Then on one half cycle the cross-over flux begins slowly part way through the half cycle. Its rate of change increases (as the increase of flux in the additive legs with rising current during the half cycle produces greater saturation therein) and falls again to zero as the alternating current in 19 reaches its maximum value for the half cycle. A half cycle of voltage wave (but not of sine wave shape) is thus produced in secondary winding 21 and a succeeding half cycle of opposite sign as the current half wave in 19 falls to zero. A secondary ouptut of double the frequency of the input to winding 19 is thus obtained in winding 21 and is variable by varying the control current in winding 20. To obtain an output of the same frequency as the input a D.C. bias winding (22), (Fig. 4, not shown) is arranged alongside winding 19 and produces a flux equal to or greater than that produced by the A.C. in 19. Then if e.g. this flux opposes the D.C. control flux in legs 16 and 14 the diagonal flux linking secondary 21 passes through those legs during both input half cycles and does not switch from one diagonal to the other. The control winding may be dispensed with by applying a D.C. bias to the secondary winding. The Specification describes a variety of different core shapes all of which provide four core zones in which the input and control (and bias, if any) fluxes assist or oppose one another (Figs. 7, 8, 9, 10, 15A, 15B, 15C, not shown).
