Title: Improvements in manufacture of cellulose acetate from wood pulp dried at an elevated temperature
IPC: C08B3/00
Filed: 1953-10-09
Abstract: In the production of cellulose acetate from formed wood-pulp, e.g. wood-pulp sheet, which is dried at temperatures which would render untreated pulp resistant to acetylation, the acetylating agent is applied to pulp which carries at least on its surface 0.015 to 0.5 per cent by weight, based on the dry pulp, of a water-soluble non-ionic surface active agent which is a polyethenoxy-polypropenoxy mixed ether compound, this agent being applied to the pulp prior to completion of the drying thereof. The moist pulp may be treated before or during sheet formation or, if desired, an already dried sheet may be re-activated by moistening it with a water solution of the surface-active agent and then redrying it.  The surface active agent may be a mixed polyalkylene oxide which is a polypropylene oxide-polyethylene oxide polymer containing at least one relatively lipophilic polypropylene oxide radical and at least one hydrophilic polyethylene oxide radical.  It may be a bispolyethenoxy polypropylene oxide derived from a polypropylene oxide which is water insoluble and has a chain length of at least 13 propenoxy groups by substitution of the hydrogen in both terminal hydroxyl groups by polyethylene oxide chains.  For rendering the final compound water-soluble there is in general required a content of at least 20 per cent of ethylene oxide, but 40-70 per cent is preferred.  The surface active agent may be a halopolypropenoxy polyethylene oxide derived from a longchain polypropylene oxide having one terminal halogen group and one terminal hydroxyl group by substitution of the hydrogen in the hydroxyl group by a polyethylene oxide chain.  The surface active agent may be an alkoxy (or phenoxy) polypropenoxy polyethylene oxide, the alkoxy group having 1-7 carbon atoms, or it may be a bispolypropenoxy polyethylene oxide.  It may be a chloropolypropenoxy polyethylene oxide in which a chloropolypropylene oxide of specific viscosity 0.257 in a 4g/100 m.l. benzene solution at 25 DEG  C. is substituted by one polyethenoxy chain equivalent in weight to 90 per cent of the total weight.  It may be a methoxy polypropenoxy polyethylene oxide in which the polyethylene oxide chain is equivalent to 60 per cent of the total weight and of which the average composition is 14.5 propenoxy groups and 29 ethenoxy groups.  It may be a bispolypropenoxy polyethylene oxide in which polyethylene oxide of an average of 36 ethoxy units is substituted at both ends by polypropylene oxide chains which together have an average of 17 propenoxy units.  The surface active agent may be applied in the form of an aqueous solution or dispersion to the moist wood pulp by spraying or by means of a moistened roller, or by immersion.

Abstract: 402,917. Electrically-operated valves. GRAY, W. T., Darroch, Wainwright Road, Altrincham, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Oct. 7, 1932, No. 27984. [Class 135.] The pressure of fluid flowing from a source 3 to a receiver 4 is controlled by a valve 12 and a relief valve 16 both valves 12, 16, being operated in accordance with the variations in the voltage or current of an electric circuit. The valve 12 has a stem 15 contacting with a metal diaphragm 11 and is biased towards the closing position by a light spring 13. The diaphragm 11 supports a stem 10 guided by a sleeve 7 and carrying an armature 9, the sleeve 7 being surrounded by a solenoid 5. A handle 18 fixed to the armature 9 enables the valve 12 to be manually operated. The actuating means for the relief valve 16 is similar to that for the valve 12. The voltage or current of the circuit of the solenoid 5 tends to open the valve 12 against the action of the fluid pressure on the diaphragm 11 and spring 13 so that the pressure of the fluid in the receiver 4 is retained at a minimum pressure corresponding to the voltage or current of the solenoid circuit. Excess of pressure in the receiver 4 above a maximum corresponding to the electric circuit in the solenoid of the relief valve 16 is relieved by the opening of the latter.

Abstract: 535,768. Motor fuels. EVERY, C. E. (Autoxygen, Inc.). Sept. 19, 1939, No. 28141/38. [Class 91] Motor fuel consists of an emulsion of water in hydrocarbon oil containing an amine soap as emulsifying agent. The soap may be mixed initially with the oil, or fatty acid may be dissolved in the oil and the amine in the water. Preferred soaps are those obtained by combining an amine, e.g. methylamine, with the acids of corn, linseed, or cottonseed oils. Suitable proportions are 3 per cent. of soap in an emulsion of 35-42 per cent. of water with 65-58 per cent. of petrol, or 15-20 per cent. of water with 85-80 per cent. of Diesel fuel. Preferably the water is dispersed to a particle size of 0.1-0.25 micron, e.g. in a colloid mill. A concentrate may be prepared to which oil and water may be added as desired, e.g. in the fuel tank. A suitable concentrate is 50lb. of the methylamine soap of the acids of linseed oil with 100lb. of petrol and 100lb. of water; it is added to 1,000lb. of gasolene and then 800lb. of water dispersed therein.

Abstract: 603,563. Drawing wire. MARSHALL, SONS & CO., Ltd., and RICHARDS, S. H. Oct. 25, 1945, No. 28150. [Class 83 (iv)] [Also in Group XXXV] In a wire-drawing machine in which the speed of a drawing-block is controlled by means associated with a spring-loaded jockey pulley around which the wire passes, a damping device is coupled with the speed control means so that the latter is influenced by the rate of change of position of the jockey pulley as well as by its actual position at any time. Such an arrangement is intended to prevent " hunting." The drawing-block whose speed is to be controlled is driven by an electric motor connected to a carbon pack resistance 1 linked at the top to an arm 2 carrying the jockey pulley 3 and at the bottom coupled to a piston 4 in a dashpot 5, The action of the dashpot prevents an immediate movement of the piston 4 under the action of a spring 6 consequent upon a movement of the jockey pulley. In a modification, the carbon pack rests on a fixed base and its upper end is connected to a pivoted lever which is also connected to the dashpot piston and to the arm 2. In a further form, an electrical damping means is employed, the resistance 1 being connected in series with another resistance such as an electric lamp 12 whose resistance varies with temperature. Specification 539,588 is referred to.
