Title: Polymers of tertiary esters
IPC: C08F22/14
Filed: 1961-05-19
Abstract: Polymers of tertiary esters of an aliphatic mono- or di-carboxylic acid which contain monoethylenic unsaturation are made by polymerizing the esters in the presence of a catalyst formed by contacting (1) a metal alkyl of the formula, MRmR1n where m is an integer of 1 to 3, n is an integer of from 0 to 2, M is a metal belonging to Group I, II, or III of the Mendel<\>eeff Periodic System, R is an alkyl or aryl radical, and R1 is at least one alkyl, alkoxy, halogen, alkyl nitrogen, or sulphur radical, with (2) a compound of the formula, M1Xp where M1 is a transition metal of Group IVa, Va, VIa, or VIIa of the Periodic Table, or iron, or copper, X is at least one halogen, oxyhalogen, oxide, hydroxide, alkoxy, acetoxy, or benzoyl radical, and p is an integer from 1 to 4.  The tertiary ester may be copolymerized with ethylene, propylene, acetylene, styrene, a methyl styrene, or a dimethyl styrene.  The preferred esters are those formed by esterifying acrylic, methacrylic, crotonic acid, fumaric, or maleic acid with 1,1-dimethyl ethanol, 1,1-diethyl propanol, 1,1-dimethyl propanol, 1-methyl 1-ethyl propanol, 1-phenyl 1-methyl ethanol, 1-phenyl 1-methyl propanol, or 1-phenyl 1-ethyl propanol.  The polymerization is preferably effected in the presence of conventional hydrocarbons and halogenated hydrocarbons.  The polymer is recovered and the reaction terminated by treating the polymerizate with a monohydric alcohol.  Catalyst systems exemplified are amyl sodium or n-butyl lithium and titanium tetrachloride, tri-ethyl or tri-n-butyl aluminium and titanium tetrachloride, n-butyl lithium and molybdenum pentachloride, diethyl zinc and titanium tetrachloride, trihexyl aluminium and titanium tetrachloride, triethyl aluminium and chromic chloride, or ferric chloride, and diethyl aluminium chloride and titanium tetrachloride. The polymers may be separated into stereospecific fractions by boiling with acetone, and then chloroform.  The copolymers of a tertiary ester and an alpha-olefin of 2 to 4 carbon atoms or acetylene are insoluble in boiling chloroform. The ester groups in the polymers may be converted into carboxyl methyl and ethyl groups by hydrolysis and/or esterification.  The polymers may be made into fibres and films.

Title: Improvements in the control of star-delta motor starting switches
Inventor: RESAG ERNST
IPC: H01H19/46
Filed: 1951-08-02
Abstract: 681,818. Control of A.C. motors; controllers; electrically-tripped switches. CRABTREE & CO., Ltd., J. A. Aug. 2, 1951, No. 18936/49. Classes 38 (iii) and 38 (v) Relates to automatic means for use in arrangements of the type in which a pair of contactor switches is employed for effecting the delayed change-over from star to delta connections in starting electric motors and in which the main contacts of such contactors are in the phases instead of the line. Time-delay mechanism c actuates mechanical linkage d when a predetermined period has elapsed after closure of star contactor b by operation of push-button a. The linkage comprises pivotal lever w which causes arm to turn pawl arm f so allowing spring m to open contacts i and close contacts n. The circuit of the star contactor is thus opened but the delta contactor k is not energised until contact p is closed by movement of armature b. A bar s is carried with armature k<SP>1</SP> to re-engage pawl f<SP>1</SP> and catch g when the delta contactor is closed. A practical construction of switch mechanism e is shown in Fig. 4 wherein slidable insulating plate t<SP>1</SP> corresponds to the member t. When the plate t<SP>1</SP> is depressed it turns plate f<SP>11</SP> so as to disengage it from lug s<SP>1</SP>. A spring 3 then presses plunger S<SP>4</SP> to break contacts i<SP>1</SP> and close contacts n<SP>1</SP>. A member x<SP>1</SP> is afterwards moved by the armature of the delta contactor to actuate arm s<SP>1</SP> and cause bracket s<SP>2</SP> to move to the left. The bracket carries plate f<SP>11</SP> with it so that lug s<SP>5</SP> re-engages the aperture in the plate. When the delta contactor is opened spring 2 presses button s<SP>7</SP>, and with it the plate f<SP>11</SP> and plunger s<SP>4</SP>, to the right so breaking contacts n<SP>1</SP> and closing contacts i<SP>1</SP>. Specification 681,851, (Group XXXII], is referred to.
Patent GB-660583-A (GB)
Title: Antibiotics
Filed: 1948-07-14
Abstract: Salt-like compounds of basic antibiotics of the streptomycin type (as defined in Specification 660,582) with surface-active agents of the organically-substituted polybasic-inorganic-acid type (e.g. those enumerated in Specification 660,582) are manufactured by reacting the antibiotic (or a salt thereof) with the surface-active agent (preferably in stoichiometric amount) in an aqueous medium (e.g. by adding the surface-active agent in aqueous solution or in solid form to an aqueous solution of the antibiotic, preferably having a pH of 5-8, or by adding the antibiotic and the surface-active agent simultaneously to water), and separating the relatively water-insoluble salt-like compound (e.g. by filtration, with or without a filter aid, or centrifuging).  The salt-like compound may be used for therapeutic purposes, or converted into a water-soluble salt of the antibiotic by the action of a water-soluble relatively strong (preferably mineral) acid, e.g. by dissolving the salt-like compound in a solvent therefor (e.g. methanol), treating the solution with an aqueous solution of the acid, and precipitating the resulting water-soluble salt by addition of a non-solvent therefor (e.g. acetone, which may alternatively be added to the initial solvent whereby direct precipitation occurs on treatment with the acid), or by contacting a solution of the salt-like compound with an adsorbent (e.g. alumina) or anion-exchange resin pretreated with the acid, or by dissolving the salt-like compound in a water-immiscible solvent for soaps and treating the solution as in Specification 660,582.  The process is applicable to the recovery of streptomycin from a primary streptomycin-containing liquid (as defined in Specification 660,582) or to the purification of basic antibiotics of the streptomycin type (e.g. streptomycin as present in a primary streptomycin-containing liquid or in a solution obtained therefrom by adsorbing the streptomycin on activated charcoal and eluting it with an aqueous water-soluble mineral acid).  An antibiotic so purified may be further purified by a repetition of the process, or may be preliminarily or further purified by other methods, of which several are specified.  Examples illustrate the various features of the invention, using certain of the surface-active agents employed in the examples of Specification 660,582.  The Specification as open to inspection under Sect. 91 comprises also the use of non-aqueous solvents for the reactants, including those in which the salt-like compound produced is soluble (e.g. methanol).  In the latter case the salt-like compound may be recovered by removing the solvent and purifying the residue (e.g. by washing with water), or by adding a miscible non-solvent therefor (e.g. water).  This subject-matter does not appear in the Specification as accepted.
