Title: Process for the production of polymers and interpolymers of ethylene
IPC: C08F10/00
Filed: 1941-04-09
Abstract: High molecular weight polymers and interpolymers of ethylene are obtained by bringing ethylene, alone or mixed with one or more other polymerizable organic compounds having ethylenic unsaturation, into intimate contact with water and a peroxide compound at pressures above 50 atmospheres and a temperature between 40-150 DEG  C., preferably 60-120 DEG  C., and maintaining such conditions until the high molecular weight polymer or interpolymer is obtained.  Peroxide compounds specified are benzoyl peroxide, acetyl peroxide, acetylbenzoyl peroxide, peracetic acid and persulphates, perborates and percarbonates of alkali metals and ammonia.  Other specified polymerizable materials are propylene, butylene, 1,2-dichloroethylene 2-chloropropene-1, methyl and propyl vinyl ethers, methyl and ethyl vinyl ketones, vinyl acetate, vinyl chloracetate, vinyl propionate, stilbene, styrene, acrylic and methacrylic acids, amides, nitriles and esters, methyl a -chloro-acrylate, methyl crotonate, diethyl itacomate, butadiene, isoprene, chloro-2-butadiene-1.3, limonene and camphrene.  Intimate contact between the reactant may be effected by vigorous agitation of the reaction mixture which may also contain water, a volatile organic liquid and/or a surface-active agent, e.g. starch, water-soluble salts of higher alkyl sulphates and sulphonates, alkali metal salts of sulphonated mineral oils, turkey red oil, &c.  Polymerization may be carried out as a batch process, or continuously.  In making polymers of ethylene, pH is adjusted between 3.5-6; for interpolymers, pH is adjusted in accordance with the other component and having regard to the particular peroxide compound employed.  Specified volatile organic liquids are iso-octane, toluene, butyl acetate, chloroform, ethyl ether, n-hexane, cyclohexane, cyclohexanone, butanol, methanol and dioxane. Examples of batch processes are given.  Specification 471,590 is referred to.

[Class 100 (i).] In a printing - machine, mechanism for controlling the descent of a delivery table 16, or the raising of a feed table, comprises means operated by the machine for moving the pile at a low speed to maintain the top of the pile at a substantially constant level, means operated by a separate source of power, e.g. a motor 102 to move the pile at a higher speed, and a yielding coupling which disconnects either of these means when the motion of the pile is obstructed. The pile table 16 is operated by chains 17 passing over fixed sprockets 24, 25 and is secured by an eye bolt 18 to a cross member 13, which supports arms 14 carrying the pile table 16, and by a bolt 19 to a bracket 21 secured to the cross-member 13. The sprocket 25 is driven by worm gearing 26, 27 from a shaft 28 which is driven either by ratchet mechanism driven from the chains 37 of the delivery mechanism, or by a shaft 66 driven by worm gearing from the motor 102. A doubleoperating clutch 67 which is operated by a forked lever 71 is held in one of three positions by a spring pin 83, Fig. 4, engaging in a notch in a link 81 pivoted to the lever 71. In the position shown in Fig. 4 the clutch is in neutral position, but, if the lever 71 is raised, the shaft 28 is clutched to a sleeve 61 of a bevel gear 59 in gear with a wheel 58 connected to a ratchet wheel 56 which is rotated intermittently by a pawl 55 on an arm 49. The arm 49 is oscillated by a rod 47, and a crank pin 46 which is driven from the delivery chains. To control the extent of rotation of the ratchet wheel 56 to allow of adjustment for the thickness of the sheets, an adjustable guard 87, which is set by means of a pointer 85 and scale 88, trips the pawl 55 after it has been rotated to the desired extent. The pawl 55 may be tripped by a guard 94 operated by lever-and-link mechanism from the tripping mechanism of the press. When the lever 71 is depressed, the shaft 28 is clutched to the shaft 66 which is geared to the motor 102. If the support 16 reaches the limit of its travel or meets an obstruction, spring coupling members 33, 34, which normally connect the shaft 28 to the sleeve of the worm 27, are separated against the action of the spring 36, and the drive of the chains is thrown out.

Abstract: 1420132 Lyophilization process NESTLE SA 1 Feb 1973 [15 Feb 1972] 4993/73 Heading F4G The invention provides a process for the separation of a solvent from a substance in solution or in suspension in this solvent. An atmosphere is created in a lyophilization chamber 1 consisting essentially of a gaseous medium capable of existing in condensed state at a temperature above -196 C. and of having at that temperature a saturated vapour pressure not exceeding 2 torrs. The medium is then condensed on a cool surface, e.g. of a condenser 8, the temperature of which is such that the saturated vapour pressure of the medium does not exceed 2 torrs, the solvent is frozen and the solvent is then separated from the substance by sublimation and is condensed on the cool surface. The gaseous medium may be carbon dioxide, sulphur dioxide, nitrogen pentoxide, nitrogen dioxide, nitrous oxide, hydrogen sulphide, ammonia, acetylene or a freon. The atmosphere is created by purging the apparatus several times with the gaseous medium by pumping out the existing atmosphere and letting in a charge of the gaseous medium alternately.
