Title: New polyethers
Inventor: ALLPORT DENNIS CHARLTON
IPC: C08G65/333
Filed: 1962-02-26
Abstract: The invention comprises compounds of the formula <FORM:0984372/C2/1> wherein R1 and R2 are hydrocarbon or halohydrocarbon groups, or one of them may be hydrogen, and R3 and R4 are hydrogen, or one of them may be a methyl group, n is greater than 1, and X is the residue of a compound XHa, having a hydrogen atoms reactive to cyclic oxides, where a is at least 2. They are prepared by reacting the appropriate primary and secondary alcohols <FORM:0984372/C2/2> with acrylonitrile or a substituted acrylonitrile in the presence of a basic catalyst, with or without an inert solvent (e.g. benzene). Formation of insoluble material is kept to a minimum by streaming air or oxygen through the mixture at a temperature below 15 DEG  C.  Antioxidants may assist this effect.  The polyether alcohols may be prepared by condensing epoxy compounds (e.g. propylene oxide, butylene-1 oxide, styrene oxide and epichlorhydrin) with the compounds XHa, which may be alcohols, polyols, amines, amides or water, or by polymerizing the epoxides alone.  The examples describe the reaction of polyoxypropylene diols with acrylonitrile in the presence of sodium methoxide, 40% aqueous trimethyl ammonium hydroxide, or 50% aqueous potassium hydroxide.ALSO:The invention comprises compounds of the formula <FORM:0984372/C3/1> wherein R1 and R2 are hydrocarbon or halohydrocarbon groups, or one of them may be hydrogen, and R3 and R4 are hydrogen atoms, or one of them may be a methyl group, n is greater than 1, and X is the residue of a compound XHa, having a hydrogen atoms reactive to cyclic oxides, where a is at least 2.

Patent GB-657867-A (GB)
Title: Vinyl resin coating
IPC: C09D129/04
Filed: 1949-03-17
Abstract: Coating compositions comprising a water-insoluble hydroxylated vinyl resin, chromium trioxide and phosphoric acid are made by adding an aqueous mixture of chromium trioxide and phosphoric acid to the resin dissolved in an organic solvent.  In a modification the resin in the above compositions may be precipitated by the addition of a non-solvent, recovered, and re-dissolved in a solvent such as methyl isobutyl ketone.  Some of the resins, e.g. copolymers of vinyl chloride and vinyl acetate, may be dried before re-dissolving.  The initial resins may be partial acetals of polyvinyl alcohol with aldehydes such as formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, valeraldehyde or hexaldehyde, partially hydrolysed polyvinyl acetate, partially hydrolysed copolymers of ethylene and vinyl acetate, or partially hydrolysed copolymers of vinyl chloride and vinyl acetate.  Specified solvents for the resins are methanol, ethanol, isopropanol, butanol, toluene, ethyl acetate, and ethoxy- and butoxyethanol.  The compositions may include pigments such as magnesium silicate, zinc or lead chromate.  The phosphoric acid may be mixed with the aqueous solution of the chromium trioxide as a solution in a solvent such as acetone or ethanol. The compositions are used for coating metal surfaces such as mild steel, galvanized iron or aluminium.
Patent GB-399806-A (GB)
Title: Improvements in or relating to protective systems for sectionalised electric supply networks
IPC: H02H7/26
Filed: 1932-03-11
Abstract: 399,806. Protective cut-out arrangements. ROSS, T. W., 10, Broadoaks Road, Sale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. March 11, 1932, No. 7383. [Class 38 (v).] A protective system for a sectionalized network comprises a pilot circuit in each section, which circuit serially connects together at all times the windings of two relays controlling the trip circuits of the breakers at the ends of the section, and is not normally energized for protective purposes but is energizable only on the occurrence of a fault in the section by protective relay means for the ends of the section. The pilot circuit is thereby connected to a separate auxiliary source, and the protective relay means prevents current circulation from the auxiliary source to the windings of the tripping-controlling relays, except on the occurrence of such a fault in the section when power only flows into the section, whereupon current flows from the source and operates one or both trip-controlling relays to trip the breakers. In Fig. 1, the pilot circuit P, P<1> is under control, at one end, of an overload or earth leakage relay D and a directional relay E the contacts of which are adapted to be closed with power entering section A from adjacent section C. The corresponding apparatus at the other end is shown by corresponding small reference letters. Fault in section A fed from section C only causes D, E to lift and energize both trip coils K, k from battery M over closed contacts d<1>, D<2>, E<1>, both circuit-breakers B, b being thereby tripped. If an internal fault is fed from section c also, relays d, e .both lift and the trip coils are energized by batteries M, m in series over contacts D<2>, E<1>, d<2>, e<1>. With a through left-to-right fault, D, E, d lift, but e remains unoperated, so that no trip coil circuit is made. In Fig. 2 the contacts of the relays E, e are arranged to open with power inflowing at their respective ends and the trip coils have greater resistance than the pilot circuit. With an internal fault fed from both ends, relays E, e open, and relays D, d close, their contacts, so that the trip coils are connected directly to their respective batteries M, m. If, however, the end C only is feeding the fault, d, e remain unoperated ; the trip coils K, k will be energized from battery M over contacts D<2> and the pilot circuit. With a through left-to-right fault D, d, e will operate, but neither trip coil will be energized as M, m are in opposition over the pilot circuit and the trip coils are shorted by the contacts e<1>, d<1>, D<2>, d<2>. As the pilot circuit is only in use during fault conditions, at other times it may be used for purposes of communication, and the system for introducing the communication currents may be permanently superimposed on the pilot circuit.
