Abstract: 1300936 Laminates CIBA-GEIGY (UK) Ltd 19 Aug 1970 [9 Sept 1969] 44579/69 Heading B5N [Also in Divisions C3 and D1] A solution of the resin described below was applied to a layer of parallel carbon fibres, the layer stood for 1 hour then dried for 16 hours in a 70C. oven. Nine such layers were laminated together under heat and pressure. In an openended mould, triglycidyl isocyanurate, prepared by the reaction of cyanuric acid and epichlorohydrin, is reacted and heated in the liquid state, with a deficiency of a primary aromatic monoamine (0À5-0À05 amino hydrogen equivalents per 1À2 epoxide group), and the resulting mixture of triglycidyl isocyanurate and the epoxy containing adduct, to which a curing agent is added, forms the resin of a carbon fibre-resin composite. The amine may be aniline, or aniline carrying one chlorine, methyl or ethyl substituent on the ring. The triglycidyl isocyanurate contains at least 8 epoxide equivalents/kg. before reaction with the amine. The reaction may be carried out in a diakyl ketone containing not more than 6 carbon atoms, or in a chlorinated hydrocarbon containing not more than 4 carbon atoms, the solvent being slowly distilled, then heated to a maximum temperature of 100, 150 or 175. Alternatively the amine may be added in portions to the molten triglycidyl isocyanurate. A large list of curing agents is given, anhydrides of dicarboxylic acids, polyamines and boron trifluoride complexes being preferred.

A magazine slide changing device comprises a claw 23 fixed to a blade spring 24 mounted on a transverse member 22 carried on a slider which is manually or motor-driven. A slide returning from the projection position is deflected away from claw 23 by arm 29a of a spring 29 and passes over the wedge shaped edge of a partition 15 in the slide shaft 9 into the gap between the inclined face 15c and the adjacent slide, when due to the spring-loaded plate 17, the slide carrying frame 16 is advanced by one slide along the shaft . 9. At the end of the return stroke, claw 23 slips over the edge of the next slide 27a until it abuts surface 28 of the frame retaining ledge 13. By this means, the claw can engage only one slide at a time, since the distance "b" is less than the smallest slide thickness.

Title: Method for producing monoalkyl ethers of dihydric phenols
Filed: 1961-12-14
Abstract: Monoalkyl ethers of dihydric phenols devoid of alkyl substitution on the nuclear carbon atoms are obtained by reacting a mixture of the dihydric phenol and an inert, water-immiscible solvent for the monoalkyl ether (4-8 parts by wt. of solvent to 1 part by wt. of dihydric phenol) at a temperature ranging from 65-100 DEG  C. with an alkali-metal hydroxide and an alkylating agent, such as an alkyl halide, alkyl sulphate or alkyl toluene sulphonate; the alkali-metal hydroxide being added gradually to the heated mixture as an aqueous solution.  The monoalkyl ether formed is isolated from the inert solvent by vacuum distillation. Small quantities of the corresponding dialkyl ethers are also formed. Monoalkyl ethers of dihydric phenols mentioned are p-hydroxyanisole, resorcinol monomethyl ether, guaiacol, resorcinol monoethyl ether, hydroquinone monoethyl ether and catechol monoethyl ether.  The inert solvent used may be benzene, ethylene dichloride, toluene, or xylene, and preferred alkylating agents are dimethyl sulphate, diethyl sulphate, propyl bromide, butyl chloride, butyl bromide and butyl toluene sulphonate. Examples are given illustrating the production of the monomethyl ethers of hydroquinone, resorcinol and catechol, and the production of the monoethyl ether of catechol.

Yarns are spun by propelling loose fibres into an intense electrostatic field in a central zone of which the fibres accumulate in parallelised form to commence to form yarn which is spun by drawing the fibres away from the field through a rotating clamp and passage the clamp forming at least apart of an electrode for creating the field. A sliver of flax or cotton from a can 1 is drawn through a condensing funnel 2, over a feed table 3 by a fluted roller 4 and introduced into a casing 6 in which a drum 5 having projecting teeth or needles disintegrates the sliver and blows the loose fibres through a duct 7 into an electrostatic field maintained between conical electrodes 9, 10. The latter has a central aperture in which is located the forward end of a twisting tube 11. The fibres become parallelised along the axis AB and are drawn through the twisting tube and spun into yarn thereby. The tube 11 includes a spherical ball 12 in contact both with a rotating circular seat 21 and with a rotating sleeve 17 which is spring urged against the ball, these members forming the rotating clamp and passage through which the yarn is drawn. In a modification (Fig. 2 not shown) the fibres are blown into the field along the axis instead of transversely.
