Title: Separating ternary mixtures by rectification
IPC: C07C7/04
Filed: 1961-07-31
Abstract: <PICT:0933328/III/1> The separation by rectification of ternary mixtures which are normally gaseous in which two components form an azeotrope is effected by fractionation in a first zone from which is withdrawn a fraction comprising a major proportion of the non-azeotrope component together with the other two components in a ratio such that they may be separated in a rectification zone without the azeotropic point being reached and rectifying the withdrawn fraction to separate one of the azeotropic components.  A mixture of ethylene with acetylene and ethane is fed by line 3 into rectifying column 1 where ethane is removed through line 4 as liquid and gaseous ethylene through line 5.  A liquid mixture is removed by line 13 which contains 1-7 times as much acetylene as ethane and for example contains 98% ethylene, 0,8% ethane and 1,2% ethylene.  This is separated in column 2 into acetylene or an acetylene concentrate through line 14 and a gaseous ethaneethylene mixture which is returned to column 1 by line 15. The separation of carbon dioxide and propylene mixed with ethylene or hydrogen sulphide is also referred to.

Abstract: 535,397. Braiding machines. STANDARD TELEPHONES & CABLES, Ltd. Oct. 13, 1939, No. 27847. Convention date, March 3. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 29, 1940.] [Class 74 (i)] [Also in Group XXXVI] A retractile electric cord, as for use with a telephone, has elastic strands applied along the conductors and the whole covered with a braided cover tensioned to make the cord self-coiling. The strands of the braid in one direction may be tighter than in the other. Certain strands may be elastic and applied under tension or the braiding may be more readily compressed on one side than the other as by varying the weave from "one over one" on the outside to one over more than one or even to flat laying on the inside. One of the conductors may be twisted and of greater length than the others so as to tend to form convolutions of greater diameter, the braid being looser over this conductor as by applying it over a shield, subsequently removed, covering the conductor while it is being braided. Means for effecting the variations in the braiding are shown in the figures, Fig. 2, a Wardwelltype braider with conductors 52, elastic strands 50 tensioned by rollers 46 and two series of rotating cops 8, the finished cord 53 being wound under tension on a spindle 25. For effecting the loosening of the braid over the inner conductor, the cord is braided while a removable shield covers one conductor, Fig. 3. The Specification, as open to inspection under Sect. 91 comprises also a maypole type of braider with tensioning means for the elastic threads and a knurled take-up spindle 25. This subjectmatter does not appear in the Specification as accepted.

Abstract: 940,549. Vacuum-formed thermoplastic resin sheets. MONSANTO CHEMICALS Ltd. June 29, 1962 [Aug. 1, 1961], No. 27853/61. Headings C3P and C3Q. A sheet made from a thermoplastic resin composition containing from ¢ to 10% by weight based on the resin of an inert desiccant, is vacuum-formed. Thermoplastic resins mentioned are styrene based resins e.g. impact polystyrenes and styrene and α-methyl styrene copolymers. The impact polystyrenes are polystyrenes that have been modified either before or after polymerization by incorporation of a rubber (natural or synthetic, e.g. styrene-butadiene rubber). Other styrene resins mentioned are copolymers of styrene with α-methylstyrene or acrylonitrile and styrene/butadiene/acrylonitrile terpolymers. Other resins specified are polymers of vinyl chloride, acrylonitrile and acrylates such as methylmethacrylate. The inert desiccant is normally a solid e,g, metal oxides such as calcium, barium and magnesium oxides; magnesium perchlorate and fused calcium sulphate. The desiccant and resin can be mixed by tumbling the former with particles of the resin in a drum, optionally followed by extrusion into a strand which is then chopped to form pellets. Preferably the desiccant in the form of a dispersion in a carrier liquid e.g. a mineral oil, is mixed with particles of the resin. In the example, circular sheets made from a composition comprising pellets of toughened polystyrene containing 8% of styrene/butadiene rubber, polystyrene pellets, zinc stearate and a dispersion of calcium oxide in mineral oil, were vacuum-formed.

Filed: 1960-08-12
Abstract: Derivatives of polyenes (polymerization products of acetylene) are prepared by reacting a polyene which contains silicon chemically bound therein with an oxygen-containing acid to give an ester-like product. The ester-like product may be converted into a water-soluble product. The silicon-containing polyene starting material may be prepared by reacting acetylene or a triple bonded derivative thereof with an organohydrogen siloxane in the presence of a metal of Group IV-VI of the Periodic Table and a finely divided transition metal or a compound of such metal which is reduced to the metal in the reaction, and which polyene has a silicon content with the range 0.01 to 10 as described in Specication 956,369. The oxygen-containing acid may be sulphuric, acetic, nitric, persulphuric and chlorine water. The sulphuric acid may be used in the presence of a catalytic amount of mercuric oxide while the acetic acid may be used together with acetic anhydride in the presence of anhydrous zinc chloride. The ester-like products may be hydrolysed, using a dilute acid or alcohol into water-soluble polyols while the sulphuric acid reaction product can be converted by reaction with alkali to a water-soluble alkali salt of the sulphated product.

Title: Method of Strengthening Glass
Inventor: POOLE JAMES PURVIS
IPC: C03C21/00
Filed: 1967-06-22
Abstract: 1,193,306. Strengthening glass chemically. BROCKWAY GLASS CO. Inc. 22 June, 1967, No. 22810/67. Heading C1M. A soda-lime glass body is strengthened by replacing O- - and/or OH- ions in the surfacelayer with F- ions, thus increasing the viscosity, and hence the strain point temperature, of the surface layer, and then cooling the body through both the surface-layer and the interior strain point temperatures. The surface-layer sets sooner than the interior glass and hence a compressive strain is produced in the surface-layer. The replacement may be achieved by contacting the body with a fluorine-containing gas or liquid, e.g. a fluorine-containing metal salt, e.g. a fluoride or fluoroborate of Sn, Pb, Zn or Ti; the contact may be at above the strain point temperature of the glass. In an example glass tubes at 1200‹ F. are sprayed with a fluorinecontaining salt solution for 20 seconds and the glass is refired at 1200‹ F. and cooled. The glass may be cooled slowly under annealing conditions; or it may be cooled more rapidly so as to produce conventional thermal tempering in addition to the surface-viscosity change effect of the present invention. The fluorine-contact may also be performed slowly or intermittently.
