Title: Improvements in and relating to the manufacture of synthetic rubber
IPC: C08F36/04
Filed: 1928-01-16
Abstract: 283,840. I. G. Farbenindustrie Akt.- Ges. Jan. 14, 1927, [Convention date]. Emulsions, making. - Hydrocarbons suitable for the manufacture of synthetic rubber, such as butadiene, isoprene, and dimethylbutadiene, are emulsified and are then polymerized in the presence of oxygen and/or of substances yielding oxygen. The medium in which the emulsion is prepared may be an inert substantially aqueous liquid or solution or a water-containing viscous liquid, and in this connection reference is made to solutions of soaps, albuminous substances, salts of sulphonated fatty acids and of aralkyl sulphonic acids and saponin, and also to aqueous suspensions of oils. For accelerating the polymerization, it is preferred to employ an alkaline oxygen-yielding substance such as sodium perborate, potassium percarbonate or barium peroxide, but other oxygen-yielding substances also may be used with the addition, it may be, of a small amount of alkali. In one example, a mixture of isoprene and dimethylbutadiene is emulsified in water containing egg albumen and soap, and polymerization is effected in the presence of gaseous oxygen. In another example, sodium perborate is added to a mixture of isoprene, water, and sodium or potassium oleate, and the mixture is emulsified in the presence of air; polymerization is then effected at 60-70 C. In a further example, an emulsion of isoprene and butadiene in an aqueous solution of sodium isobutylnaphthalene sulphonate is treated with potassium percarbonate, whereafter the hydrocarbons are polymerized. Specification 14556/12, [Class 2 (iii), Dyes &c.], is referred to.

Title: Rocket motors
Inventor: ALLEN SIDNEY
IPC: F02K9/72
Filed: 1952-01-21
Abstract: 763,962. Jet propulsion plant. ARMSTRONG SIDDELEY MOTORS, Ltd. Oct. 21, 1952 [Jan. 21, 1952], No. 1615/52. Class 110 (3). [Also in Group XII] In a rocket motor designed to operate on a liquid fuel and a liquid oxidizer as propellent, the whole or at least the main portion of the oxidizer is admitted to a preheating portion of the combustion chamber, upstream of the fuel supply thereto, and is subjected to a heating means by which it is evaporated and heated to a relatively high temperature before the fuel is added, which high temperature may be such as to cause spontaneous ignition with the fuel. Referring to Fig. 2, a small amount of liquid fuel is admitted through an injector 46 and liquid oxygen is delivered from an annular chamber 49 through holes 50 on to a baffle 51 so that it cools the walls of the ring 15 whilst evaporating. The baffile 51 may be provided with inclined holes 53 so that some of the liquid oxygen is directed towards the injected fuel which is ignited by plugs 47, 47a. The heated mixture then passes at high velocity through a constriction 55 where it picks up a further supply of liquid oxygen from the spray holes 41 and later from the spray holes 42. The evaporated oxygen then passes to the main combustion chamber, Fig. 3, where liquid fuel from a pipe 67 is sprayed through holes 61 on to annular baffles 63, 64. The ring 19 of the main combustion zone has on its inner face a helical ridge 22 which engages a heat-resistant liner 23. A coolant, which may be water or liquid fuel, is circulated in the space between the ring 19 and the liner. The ring 18 is provided with a liner 26 and the annular space 27 between the two may be provided with coolant, either separately or from the outlet space 29 of the coolant cooling the ring 19. Radial holes 28 communicating with the space 27 allow coolant to pass along the interior of the liner 23.

Title: Spinneret for melt-spinning of artificial fibres
IPC: D01D5/253
Filed: 1966-01-13
Abstract: 1,096,093. Making spinnerets. E. I. DU PONT DE NEMOURS & CO. Jan. 13, 1966 [Jan. 13, 1965], No. 1665/66. Heading B3A. [Also in Division B5] Fabrication of orifice 10 in spinneret plate 12 adapted for melt spinning and shown in Figs. 1 to 4 is started by drilling entrance hole 18 to the desired depth in a blank of stainless steel or other suitable metal. There may be one or more orifices 10 in each spinneret plate 12. Normally, the drill does not have the proper tip angle to form the divergent section 34, which in that case is either formed with a punch or by removing a small amount of material with a shaped drill. Another drilling or punching step is used to form the second divergent section 32. The first divergent section 26 is formed by a further punching step using a shaped punch. The protuberance of deformed metal thereby formed on the discharge face 16 is removed by rubbing the spinneret plate on abrasive paper. The capillary or discharge section 20 of orifice 10 is formed with a shaped punch. The protuberance thereby formed on the discharge face 16 of the spinneret plate is removed by rubbing and any burrs thereby left at the discharge orifice are removed by alternately cleaning out the capillary section with the shaped punch used to form it and rubbing the face 16 a sufficient number of times. The face of the spinneret is then given a high polish. An alternative method for removing burrs from the discharge orifice 20 is to place the face 16 on a lapping wheel which has a " long nap " cloth. If a rounded edge is thereby formed between walls 23, 24 and discharge face 16, the essential sharp edge at this point is produced by a light final lapping step with a fine abrasive followed by a final polishing step.

Abstract: Liquid sulphatable or sulphonatable organic compounds are sulphated or sulphonated with undiluted sulphur trioxide vapour contained in a chamber at a pressure substantially below atmospheric pressure, wherein the material to be reacted with the sulphur trioxide vapour is pumped in the liquid state through a separate contacting zone as a thin continuous turbulent stream or sheet of high velocity, at a molar flow rate substantially exceeding the molar flow rate of the sulphur trioxide into the contacting zone, and the reaction product is rapidly withdrawn from the contacting zone.  The organic starting material is suitably a fatty alcohol or an alkyl benzene and the reaction is preferably effected at a temperature not exceeding 120 DEG  F. and at a pressure of 15 mm. Hg or less.  The initial molar rate of introduction of the organic material is suitably 30 to 50 times the molar rate of introduction of the sulphur trioxide and the product of the reaction may be removed to a neutralization operation in accordance with conventional techniques with any of the alkali metal or alkaline earth metal hydroxides, alkanolamines or amines to form the respective salts of alkyl sulphuric acid. In specific examples the organic reactants are lauryl alcohol and a straight chain alkyl benzene containing principally 12 carbons in the chain but some alkyl benzenes having straight chain alkyl groups containing 11-15 carbon atoms are also present.  A suitable form of apparatus for carrying out the reaction is described.
