Patent GB-1107374-A (GB)
Title: Cold soluble cyanamide derivatives of amylaceous materials
Inventor: NOORD KLAAS GERHARD DE
IPC: C08B31/00
Filed: 1964-04-16
Abstract: Dry cationic amylaceous material is made by reacting amylaceous material with cyanamide or an alkali metal or alkaline earth metal salt thereof in an aqueous medium at pH greater than 9, and then heating an aqueous medium containing the reaction product in order, if the product is not gelatinized, to gelatinize it, and, in any event, to dry the product, the pH of the aqueous medium immediately before the heating being below 4.  The amylaceous material may be untreated starch, starch derivatives, e.g. hydrolysed starch, or starch ethers or esters, or amylose or amylopectin.  Reaction with cyanamide is suitably carried out below 40 DEG  C., and subsequent heating may be effected at atmosphere or under reduced pressure.  If the cyanamide-starch reaction product is not in colloidal solution, the product may be gelatinized while being dried, suitably on a steam-heated drum. In one embodiment, the reaction product is removed from the reaction medium and washed before being re-suspended in an acid aqueous medium for heating and drying. Alternatively washing may be omitted.  The solubility of the dry cationic product may be improved by the addition, to the aqueous medium before heating, of certain salts which make it possible to increase the pH at which gelatinization is carried out or drying is started. Salts which buffer between pH 2.5 and 4.0 are suitable.  Specified salts are monoalkali orthophosphate, dialkalipyrophosphate aluminium sulphate or phosphate, and the chlorides of calcium, magnesium or zinc.

Title: Process for obtaining effects or designs on yarns, threads or fabrics composed of orcontaining cellulose esters or ethers
IPC: D06Q1/02
Filed: 1934-05-30
Abstract: Designs are produced on textile materials containing cellulose esters or ethers by applying locally an organic peroxide and subjecting the material to the action of dry or moist heat to effect local destruction of the material.  The organic peroxide, e.g. benzoyl peroxide may be dispersed in an organic solvent, or may be used in colloidal suspension, or it may be dissolved in an organic solvent immiscible with water and the solution obtained dispersed in a printing paste.  A suitable solvent for the latter purpose is benzyl acetate.  In an example, a yarn composed of threads of cotton, silk, and cellulose acetate is impregnated with a dispersion containing benzoyl peroxide, dried, and submitted to the action of heat.  In a second example, a velvet having a silk foundation and a cellulose acetate nap is printed with a paste containing benzoyl peroxide.  The fabric is then dried and steamed at 100 DEG  C.  In another example, a dyed velvet having a cotton foundation and a cellulose acetate nap is printed with a paste containing benzoyl peroxide, diethylene glycol, and zinc formaldehyde sulphoxylate, steamed, dried, and brushed.  In a further example, a voile in which the warp and/or weft are composed of both regenerated cellulose and cellulose acetate threads is printed in some parts with a paste comprising benzoyl peroxide and butyl tartrate, and in other parts with a paste of aluminium chloride.  The fabric is dried, stoved at 110 DEG  C., and brushed.  In another example, an emulsion of benzoyl peroxide and benzyl acetate in British Gum thickener and sodium sulphoricinate is printed on the reverse of a velvet having a silk foundation and cellulose acetate nap, and the velvet is dried, heated to 110--115 DEG  C., and brushed.  In a further example, a velvet having a base of silk and a nap of cellulose acetate and regenerated cellulose is printed in three designs, the first with a paste containing benzoyl peroxide and benzyl acetate, the second with a paste of aluminium chloride, and the third with a paste containing benzoyl peroxide, benzyl acetate, and aluminium chloride.  The fabric is then dried, heated to 115--120 DEG  C. and brushed.

Abstract: 708,169. Automatic voltage control systems. MULLARD RADIO VALVE CO., Ltd. June 30, 1952, No. 16393/52. Class 38(4) A series valve type of voltage stabilizer is provided with two alternative controlling amplifier valves with different preset inputs so that the stabilizer can be rapidly switched from one preset output voltage to another. The series impedance valve 1, Fig. 1, is controlled by either of two amplifying valves 2, 3, having individually adjustable grid cottages tapped off potential dividers 10, 11, 12 and 13, 14, 15, and a common reference voltage provided by a neon stabilizer tube 8 in their common cathode circuit. A keying valve 17 in the grid/cathode circuit of valve 3 can be made conductive by a control pulse, and then valve 3 cuts off and the output voltage rises to its upper value controlled by valve 2. Conversely, with valve 17 cut off, valve 3 is conductive and the output voltage is controlled at its lower value. To reduce the change-over time, a capacitor may be provided in parallel with resistors 10 and 11 and another in parallel with resistors 13 and 14. For transient compensation of the neon stabilizer tube two series combinations each of a resistor and a capacitor may be connected in parallel with the tube, one having a time constant of approximately a tenth of the other. In a modification, Fig. 2, the control valves 2, 3 are pentodes, and the reference voltage is obtained across the resistor 31 of a cathode follower 30 having its screen voltage stabilized by a neon stabilizer 32, the voltage across which is also applied via a variable resistor 34 to the screen grids of valves 2 and 3, a portion of this latter voltage being applied also to the control grid of the cathode follower 30. Thus a variation in the screen grid current of valve 2 or 3 causes a variation in the control grid voltage of valve 30, and it is possible by adjusting the resistor 34 to make the impedance of the cathode follower as a reference voltage source substantially zero.
