Abstract: 1,147,594. Producing polyoxymethylene filaments. FARBENFABRIKEN BAYER A.G. 1 April, 1966 [1 April, 1965], No. 14636/66. Heading B5B. [Also in Division C3] Polyoxymethylene filaments are produced by dissolving a polyoxymethylene having a molecular weight of 20,000 to 125,000 or a copolymer thereof containing not less than 90% by weight of polyoxymethylene, the polyoxymethylene or the copolymer thereof having an inherent viscosity of 0À8 to 2À5, in a polar organic solvent having a boiling point above 160‹ C. at a temperature up to 160‹ C. and extruding the solution through a multi-orifice spinneret at a temperature within the range 80 to 160‹ C. into a coagulating medium and stretching the filaments at an elevated temperature advantageously within the range 100 to 140‹ C. The solution may be extruded into a heated spinning cabinet through which a preheated inert gas is passed on into a precipitating bath. The inherent viscosity is calculated according to the formula the viscosity of a 0À5% solution of the polymer in p-chlorophenol being measured at 60‹ C. The solvent may be N,N-dimethyl-acetamide, N- methyl pyrrolidone (both used in the examples), N,N-dimethylformamide, butyrolactone, w-cresol, p-chlorophenol, dimethylsulphoxide, tetramethylene sulphone, or hexamethylphosphoric acid amide. The polyoxymethylene has a molecular weight of preferably 30,000 to 85,000 and its inherent viscosity is preferably 1À0 to 2À0. The polyoxymethylene may be a formaldehyde polymer having end groups stabilized by esterification, or a copolymer of trioxane, e.g. trioxane-dioxolane, trioxane-oxthiolane, trioxane-1,3,-dioxane or a trioxane-epichlorhydrin copolymer with a comonomer content of 0À1 to 10%, preferably 1 to 5%. In the production of the filaments by wet spinning the precipitation medium may advantageously be an alcohol of relatively high boiling point such as butanol, octanol, glycerine, ethylene glycol or hexanetricol. The filaments may be stretched in the precipitation bath. The spun filaments still contain about 0À5 to 5% of the spinning solvent and may therefore be stretched at stretch ratios up to 15: 1 without breakage.

Patent GB-1093103-A (GB)
Title: Process for preparing alkene-sulphonates
IPC: C07C309/20
Filed: 1965-04-08
Abstract: Alkene sulphonates are obtained by reacting 1 mole of an a -olefin containing 6-22 carbon atoms with 1.5-2.5 moles of gaseous SO3 at a temperature up to 150 DEG  C., and hydrolysing the intermediate so formed in an aqueous solution of a strong base which is kept in permanent excess throughout the hydrolysis.  The a -olefin is preferably used in finely divided form e.g. as a spray.  The SO3 may be used in admixture with an inert gas e.g. air or nitrogen.  As the strong base, an alkali metal hydroxide such as sodium hydroxide may be used.  In a preferred method the a -olefin is sprayed from a nozzle into a stream of air containing the SO3.  After residence times varying from 0.3-0.8 second, the product is taken up in an excess of sodium hydroxide solution on a packed column, and the resulting solution heated e.g. for four hours at 80 DEG -100 DEG  C. The products are obtained by neutralizing the resulting solution e.g. with dilute sulphuric acid and evaporating to dryness. They are useful as detergents.  If desired they may be freed from inorganic salts present, especially sodium sulphate, by treatment with 50% aqueous isopropanol at 50 DEG  C. followed by addition of sodium carbonate, when the alkene sulphonates remain in the organic layer and the salts in the aqueous layer.  Extraction with ethanol may also be used.

Title: Pressure/vacuum operated controller
IPC: F15B21/08
Filed: 1962-04-18
Abstract: 961,364. Fluid-pressure servomotor control systems. McNAMEE INDUSTRIES PTY. Ltd. April 18, 1962 [May 4, 1961], No. 15017/62. Heading G3P. In a vacuum operated controller, particularly for a boiler flue dust removal plant, a remote switch opens solenoid valve S.V.A., Fig. 1 allowing hydraulic pressure to act on the small side A of piston 11 which moves to the right since the large side B is open to atmosphere through restriction RV and three-way valve DV which is opened to atmosphere when its operating bellows 17 is open to a low vacuum on atmospheric pressure in the dust extraction pipe 18, Fig. 2. A pawl on the piston rod 12 rotates a cam drum via gear 13 so that after 50% piston stroke cam 15f actuates a holding switch for S.V.A. Also at 50% of stroke a pin on the piston rod opens valve V1 and bellows 17 to atmosphere and disconnects them from pipe 18. At 65% of stroke, cam 15a operates a control valve for a hydraulic valve 19a on the first dust chamber 20a. At 70% of stroke, cam 15e operates a control valve 19e for opening a hydraulic water ejector valve 21 and dust is sucked out of hopper 20a and discharged as a slurry from pipe 18. At 19% of stroke the piston pin operates valve VI to reconnect bellows 17 to pipe 18 and as the vacuum rises n the pipe due to the water ejection of the dust, yellows 17 actuates valve DV to connect pressure rom S.V.A. to the side B of the piston which moves eftwards to recock for commencing a new stroke. Vithin a few minutes after dust ejection the vacum falls, bellows 17 opens valve DV to atmosphere and drains side B of the piston so that it recom nences a working stroke to the right, the next dust valve 19b opening before 19a closes so that no undue suction load is placed on the dust valve closure members. If vacuum rises higher than normal, indicating a controller fault or blocked hopper, an alarm operates and the controller automatically "steps over" the blocked hopper by actuating a pressure switch associated with valve S.V.B. and switch LS3 which is actuated by a piston rod cam at the extreme end of its working stroke. During the last right hand stroke, all valves 19a-19c are placed in a neutral open center position, the ejector valve closed, and since no vacuum exists in pipe 18 to operate bellows 17 and open valve DV and side B to pressure at 90% of stroke, the piston moves to 98% of stroke and operates valve V3 directing hydraulic pressure to side B to recock the piston and operate switches LS1, LS2 to break the holding circuit for SVA. V3 is also operated to recock the piston should a hopper be empty so that no vacuum is produced.
