Patent GB-625216-A (GB)
Title: Improvements relating to the production of phenolic ethers of glycerol
Filed: 1947-06-05
Abstract: Monophenolic glyceryl ethers are prepared by the condensation of glycerol in the presence of a catalyst with a phenolic reagent consisting at least in part of a homologue of phenol other than cresol, the phenolic reagent being soluble in glycerol under the conditions of the reaction, the relative proportions used of the glycerol and the phenolic reagent being such that the phenolic reagent is present in excess of an equi-molecular mixture, and the reaction being stopped while the reaction mixture contains the mono-ether as the major constituent compared to the di-ether. Suitable phenol homologues, which may be used mixed with phenol or cresol, are phenols substituted by monoalkyl groups larger than -CH3, e.g. isopropyl-, p-tert.-butyl-, disubstituted phenols such as xylenols of b.p. 207-230, and tar acids of b.p. 230-260 DEG  C.  The condensation catalyst may be potassium acetate or other water-soluble alkali metal salts of the lower saturated aliphatic acids, but preferably it is sodium acetate.  It is preferred to have an entraining agent present to remove water during the reaction as an azeotrope, e.g. xylene, toluene, benzene and petroleum fractions, b.p. 60-140 DEG  C.  The reaction mixture may be worked up by adding water and a hydrocarbon, e.g. benzene, when the phenolic ethers appear in the upper layer, and unreacted glycerol and catalyst may be recovered from the lower aqueous layer.  It is preferred to use an excess of 40-100 per cent of the phenolic reagent over the glycerol. In the examples, glycerol in the presence of sodium acetate is heated with xylenol (b.p. 210-225 DEG  C.), 1 : 3 : 5-xylenol, p-tert.-butyl phenol, tar acids (b.p. 230-260 DEG  C.), and p-tert.-amyl phenol to give the corresponding glyceryl ethers; in all cases a xylene entrainant is used for the removal of water during the reaction. Specification 589,821 is referred to.

[Also in Group XXXVI] A connector, which may be of the axial or flag type having a resilient blade-receiving portion 1, Fig. 1, or a ring or spade tongue, a wiregripping ferrule 3 and an insulation-gripping ferrule 6, is formed from a blank as shown in Fig. 2. The ferrules are formed from tongues 8, 9 respectively, the end 10 of tongue 8 being passed through a slot 11 and locked by tabs 15, 16 folded down on to it. Fig. 8 shows dies 23, 26 for forming the ferrules. The blank rests on the lower die 26 and the upper die 23 has parallel, arcuate surfaces 24, 25 for curling the tongues 8, 9. When the dies are in engagement continued movement of the upper one presses die 26 downwards against springs 32 thereby causing a stationary indentor 27 located in a passage 31 in die 26 to engage the base of the connector across the tabs 15, 16 and indent it into the wire as shown in Fig. 6. A modified tongue-locking arrangement is shown in Fig. 11. In this case the end 10a of the tongue 8a has a notch which is caused by upper die 23a to engage a detent 40 on the edge of a slot formed by striking out a bowed tongue 38. During the indenting operation a stationary member 41 straightens the tongue 38 thereby locking the notch and detent in engagement. Fig. 14 shows a further locking arrangement wherein the end 10b of the tongue is bent to lie along the base of the connector after passing through slot 11b and is locked by striking a tab 45 down into the tongue from the base. The final indenting of the ferrule into the wire is preferably performed at the top of the ferrule.
