Patent GB-560116-A (GB)
Title: Production of pattern effects on cellulose ester or ether materials
IPC: D06Q1/02
Filed: 1942-09-01
Abstract: A textile fabric containing filaments having a basis of a cellulose organic derivative, or a film having a basis of a cellulose organic derivative, is provided with a resist in a pattern and subjected to the action of a solution of not more than 50 per cent strength by volume of a non-volatile plasticizer in a volatile liquid which has at least some softening action on the organic derivative of cellulose, and the fabric or film is then dried at an elevated temperature.  The resist may subsequently be washed out or if it is flexible and transparent it may be permitted to remain on the material.  The resulting fabric or film presents an ornamental patterned effect.  In the case of a fabric, the resist-free portions acquire an organdie-like finish.  If desired, the resist may be applied at random <PICT:0560116/IV/1> along the length of the yarns prior to fabric formation.  The resist may be a water-soluble resin such as polyvinyl alcohol, or a gum such as gum arabic, or a protein such as albumen and casein. The plasticizer may be dimethyl or diethyl phthalate, methyl phthalyl ethyl glycollate, dibutyl tartrate, triethyl citrate, ethyl-p-toluene-sulphonamide, triphenyl or tricresyl phosphate, triacetin, or tripropionin.  The volatile solvent for the plasticizer may be ethyl alcohol, methyl ethyl ketone, or a mixture of xylene and acetone.  Woven, knitted, or netted fabrics may be treated and they may contain cotton, silk, wool, regenerated cellulose or other fibres in association with the cellulose derivative fibres.  The fabrics or films may be treated with the solution of plasticizer by impregnation, padding or spraying.  The cellulose derivative fibres may be of cellulose acetate or other cellulose ester or of ethyl, benzyl or other cellulose ether.  The ornamental fabrics and films produced may be employed for decorative sheets and wrappings, as lampshades, and, when cut to suitable shape, as place mats for table settings. Resist-printed fabric 2 is passed into trough 5 containing solution 6 which comprises a plasticizer for the cellulose derivative and a volatile solvent for the plasticizer.  The solution may be heated or cooled.  The fabric passes beneath roller 7 set below the liquid surface and then between squeeze rollers 9, 10.  If desired, a plurality of submerged guide rollers may be used, or the submerged roller 7 may be omitted, the liquid being applied by roller 10 which is partly beneath the liquid surface.  Solution 6 may be replenished through pipe 11 in hood 12.  The fabric passes through drying chamber 13 from which solvent-laden air is led to a solvent-recovery system. Specification 413,150 (as open to inspection under Sect. 91) is referred to.

Title: Process for the hydrogenative cracking of hydrocarbon oils
IPC: B01J37/26
Filed: 1963-04-02
Abstract: Hydrocarbon oils are cracked by contacting the oil in presence of hydrogen at elevated temperatures and pressures with a catalyst comprising fluorine preferably 0.1 to 5.0% by weight based on the catalyst and at least one metal of the iron group of the Periodic Table intimately associated with an acid acting support comprising at least one refractory oxide, the intimate association of the metal with the support having been achieved by contacting the support in hydrogel form with a solution of the said metals or metals, fluorine having been incorporated into the support while the support is in the hydrogel form.  The support comprises silica and at least one of the following: alumina, magnesia, zirconia and boria.  Preferably the supports comprises by weight 50% to 90% of silica and 50% to 10% alumina.  The catalyst contains 0.1% to 14% by weight of the iron group metal e.g. nickel and cobalt.  The catalysts may be prepared by contacting the hydrogel with a solution of the metal or metals the pH of the solution being 4 to 7.  The hydrogel may be prepared by (1) mixing aqueous solutions of an alkali metal aluminate and an alkali metal silicate, adjusting the pH to 7 with mineral acid, aging and then washing the hydrogel to remove alkali metal ions; (2) adding mineral acid to an alkali metal silicate solution to adjust the pH to 2, adding an aluminium salt, adjusting the pH to 7 and washing the hydrogel formed.  The hydrogel may be washed with ammonium nitrate solution to remove alkali metal ions.  The fluorine is incorporated into the hydrogel by adding hydrofluoric acid or a water soluble fluoride, e.g. ammonium or sodium fluoride, to the aluminate solution used to prepare the hydrogel.  The hydrogel is finally washed, dried and calcined at 427 DEG  to 649 DEG  C.  The hydrogenation takes place at 260 DEG  to 454 DEG  C., 10.5 to 210 atmos. gauge, a L.H.S.V. of 0.2 to 10.0 litres of oil per hour per litre of catalyst and a hydrogen to oil mol. ratio of 5: 1 to 50: 1.  The hydrocarbon feed boils above the gasoline boiling range e.g. 232 DEG  to 510 DEG C. and may be pretreated by mild hydrogenation to remove coke forming constituents and to reduce the sulphur and nitrogen contents.
