Title: Production of alkali cellulose
IPC: D06B13/00
Filed: 1947-09-03
Abstract: In the production of alkali cellulose, cellulosic material in contact with alkali solution is subjected to high-frequency sound or ultrasound wave radiations.  The frequency of the waves may be from about 1,000 to one million or more cycles per second and the waves may be generated by means such as a piezo-electric sound generator, a magnetostriction sound generator, or an electromagnetic sound generator.  The cellulosic material to be treated may be in sheet form, as a continuous web, or in disintegrated form.  As shown in Fig. 1, a sheet of cellulosic fibres 3 from a supply roll 2 is led <PICT:0641609/IV (a)/1> at a controlled rate through an aqueous sodium hydroxide solution in a vessel 5.  A transmission tube 12 of a sound generator 11 extends into the solution which is subjected to high-frequency sound wave radiations.  The sheet of fibres is passed round guide rolls 4, 6, 7 and 8, or alternatively 4, 6, 61, 7 and 8 if longer contact between the sheet and the solution is required, and is then pressed between rollers 9 to remove excess alkali solution, after which it may be either disintegrated and aged, or subjected again to the sound wave radiations.  In modifications, the web is treated with alkali and subjected to the wave radiations after it leaves the alkali bath, or alternatively, cellulose fibres of varying forms are conveyed through the irradiated alkali solution on a continuous belt.ALSO:<PICT:0641609/IV (c)/1> In the production of alkali cellulose, cellulosic material in contact with alkali solution is subjected to high-frequency sound or ultrasound wave radiations.

The compounds wherein B is a hydrocarbon when added to detergent compositions are stated to produce a more stable foam, those wherein B is sodium are stated to increase the foaming power of detergent compositions, and those wherein B is a sulphonated hydrocarbon are used as detergents per se.ALSO:Homopolymers and copolymers are obtained from compounds of the formula <FORM:1089494/C3/1> where A is H or alkyl, B is H, a metal or a monovalent hydrocarbon residue which may be substituted, e.g. by -SO3H, -SO3Na, -SO4Na and -OH groups and n is 1-4. Examples describe (i) the homopolymerization of bis-acrylamido acetic acid and (ii) its copolymerization with acrylamide, (iii) the copolymerization of oleyl bis-acrylamido-acetate with ethyl acrylate, and (iv) the copolymerization of sulpho-3-propyl bis-acrylamido-acetate with vinyl acetate.  Polymerizations (i) and (ii) are carried out in methanol using azobisisobutyronitrile catalyst while (iii) and (iv) are emulsion processes employing lauryl ammonium sulphate and ethoxylated oleyl alcohol emulsifiers and ammonium persulphate/sodium metabisulphite catalyst.  In (ii), (iii) and (iv) some of the reactants &c. are introduced during the course of polymerization. The polymers have various industrial applications.ALSO:The invention comprises compound of the formula <FORM:1089494/C2/1> wherein A is H or alkyl, B is H, a metal, or a monovalent hydrocarbon residue and n is 1-4.  The metal may be K, Na, Co or Pb, and the hydrocarbon residue may be an aliphatic residue which may be substituted by -SO3H, -SO3Na, -SO4Na or -OH.  The compounds are prepared by condensing one mol of an a -carbonyl acid with two mols of acrylamide to give the free acids which may then be modified by esterification or salification.  The condensation is carried out in an organic solvent which permits the removal of reaction water and water of crystallization azeotropically.  In Example I an acid is treated with formaldehyde to give a N-monomethylol derivative.

Abstract: The antibiotics, sugordomycins, are sugar derivatives of 2,4-di[(4,7-dihydroxy-8-methyl-coumarinyl - (3)) - aminocarbonyl] - 3 - methyl-pyrrol and have the formula <FORM:1111511/C2/1> wherein at least one of the groups R1 and R2 is a pyrroyl-(2) or 5-methyl-pyrroyl-(2) group and the other is such a group or a H atom. The sugar residues have the L-alpha-lyxopyranosyl configuration and the antibiotics form salts with bases, e.g. sodium salt and benzylamine salt.  Several sugordomycins have been isolated from a fermentatio broth:- .Sugordomycin.R1.R2 .1a.5-methyl-pyrroyl-(2).5-methyl-pyrroyl-(2) .1b.pyrroyl-(2).5-methyl-pyrroyl-(2) .1c.5-methyl-pyrroyl-(2).pyrroyl-(2) .1d.pyrroyl-(2).pyrroyl-(2) .1e.5-methyl-pyrroyl-(2).H .1f.H.5-methyl-pyrroyl-(2) .1g.pyrroyl-(2).H .1h.H.pyrroyl-(2) P.4127 The sugordomycins may be obtained by cultivating Streptomyces hazeliensis NRRL 2938 or a mutant thereof in an aqueous nutrient medium containing an assimilable source of organic carbon and nitrogen and also mineral salts.  The medium is critical and a typical medium contains split peas 3%, CaCO3 0.1%, K2HPO4 0.1% in water.  The antibiotics are isolated from the fermentation broth by extracting both the separated mycelium and the clarified broth with a polar organic solvent followed by treatment with an absorbent such as carbon or an ion-exchange resin; or precipitation by a non-solvent such as petroleum ether. Further purification is by (a) crystallization from solvents, (b) formation of benzylamine salt and (c) distribution between a water-immiscible organic solvent and an aqueous buffer of pH 6.8 to 11.  The antibiotics are separated into their components by counter-current distribution using 400 tubes in the Craig apparatus and the system isopropyl alcohol/chloroform 1:1 (lower phase) and aqueous N/15 K2HPO4 buffer of pH 8.2 (upper phase).  The sugordomycins are broad-spectrum antibiotics and may be put up into oral, parenteral and rectal pharmaceutical compositions.

The particular application is for a photo-electric or electro-optical transistor in which the photosensitive surface is at the focal point of the lens, the lens being of 3 to 4 mms. diameter.  A rod 20 of glass is supported in a rotatable chuck over a rotatable holder 11 also movable towards and away from the rod 20, the support member being formed by the -housing 10 supported on the holder 11 with its aperture 12 directly below the end 21 of the rod and the rod 20 and holder 11 being rotated at the same speed.  The end 21 of rod 20 is heated till a bulb (22, not shown) is formed, the flame then being raised so that a drop 23 is formed.  The flange 13 surrounding the aperture 12 is also heated and the holder raised, as shown in Fig. 4, till the drop 23 engages the flange 13 and spreads thereover with part 24 passing through the aperture 12. The flame 30 then heats the join between the drop 23 and rod 20 and, as in Fig. 6, the holder 11 is lowered to separate the drop 23.  A fine flame 34 is then used to heat the top of the drop so that a convex top surface 27 is formed to bring the drop to a sphere 28.  To assist spreading of the glass over the flange 13, the stainless steel housing 10 may be coated as by oxidation of the metal surface or by a thin coating of powdered soft glass.
