Patent GB-683682-A (GB)
Title: Improvements in and relating to processes for the production of vinylic ethers
IPC: C07C43/16
Filed: 1947-09-10
Abstract: Vinylic ethers are prepared by the catalytic reaction of acetylene with alcohols characterized in that the acetylene is dissolved in the alcohol at a temperature below 0 DEG  C. and a pressure of from 5 to 10 atmospheres and the resulting solution of acetylene and alcohol is fed to a reaction vessel wherein the catalytic reaction is carried out continuously in liquid phase at a temperature above 100 DEG  C. and at a pressure of from 50 to 200 atmospheres.  The product is continuously discharged, separated from unreacted acetylene, and distilled and the unreacted alcohol and acetylene are recycled.  A flow sheet (not shown) illustrates suitable apparatus and according to an example using such apparatus, a current of acetylene is conveyed by a compressor to a saturator containing isobutyl alcohol and potassium hydroxide as catalyst, the acetylene being absorped therein under 10 atmos. pressure while cooling with brine to below 0 DEG  C.  The resulting solution is pumped through a heat-exchanger and then through an externally-heated coil reactor, which may be replaced by a set of pressure vessels in series, maintained at 150 DEG  C.  The issuing products pass through the heat-exchanger to preheat incoming feed, then through a valve adjusted to maintain a reaction pressure of 80 atmos., and finally pass via a cooler to a separator where unreacted acetylene is removed, the liquid phase being distilled to recover the vinyl ether and unchanged alcohol.  A statement of prior art refers to the use, as catalysts, of alkalies and organic salts of cadmium and zinc at temperatures between 80 DEG and 300 DEG  C.  The Specification as open to inspection under Sect. 91, relates to the production of vinyl ethers by reaction of acetylene with oxygenated compounds where the acetylene is dissolved in the oxygenated compound at a temperature below 0 DEG  C. and a pressure of from 5 to 10 atmos.  This subject-matter does not appear in the Specification as accepted.

Filed: 1951-11-02
Abstract: 696,988. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 2, 1951 [Nov. 6, 1950], No. 25674/51. Class 40 (iv). In a system employing primary and secondary line finders, the primary line finders include a relay X which becomes connected in parallel with the calling party's meter Z so that if the circuit through the latter is open it is energized by the metering impulse and causes the finder to remain locked in position after the calling line is released to locate the faulty meter. The start relays such as P, P1 of the primary and secondary finders are controlled over chain allotting circuits which are grounded by line relay L when a call is made. Test relay T energizes in series with cut-off relay S, and test relay T1 in series with G (which locks) and a holding winding of P. Relay P1 holds over a winding not shown until the calling party hangs up. Upon the reply of the called party a metering impulse is applied at contact i to actuate the meter Z. Relay X does not normally operate on account of its high resistance, and it may be provided with an opposing winding in series with Z to assist this effect. If the meter is faulty however, X operates, locks in series with T, lights an alarm lamp AL and connects an auxiliary common meter ZH to the metering circuit. Thus the primary finder remains locked after the calling party hangs up, and further calls that he makes are recorded on the auxiliary meter ZH, which in effect replaces the faulty meter Z. A known arrangement which employs a relay like X in the group selector, for example, has the disadvantage that the subscriber's line remains out of service until the fault is removed.

Abstract: 1,204,989. Polymer compositions. SIEMENS A.G. 20 May, 1969 [21 May, 1968; 28 Feb., 1969 (4)], No. 25759/69. Heading C3P. [Also in Divisions H1 and H2] In a cable fitting, e.g. a joint or termination, a layer of cross-linked or vulcanized olefin copolymer is disposed between a polyolefininsulated cable and a cast resin body. The cable insulation may be cross-linked high pressure or low pressure polyethylene which is bonded to the olefin copolymer layer during the cross-linking or vulcanizing process. The process is effected by the application of heat and possibly pressure by wrapipng the layer in bandages. The layer, which may be formed from a strip, comprises two olefin components in equal molar proportions, e.g. ethylene propylene rubber, and may also contain an unsaturated hydrocarbon, e.g. a diene to form, for example ethylene propylene terpolymer rubber. Peroxides are used as cross-linking agents, and vulcanizing agents consist of sulphur and organic accelerators, e.g. mercaptobenzthiazole or tetramethylthiuramdisulphide. The cast resin body may be positioned or moulded on the layer before or after the process. The cast resin body may be epoxide resin based, epoxide resin or polyurethane resin. Polyurethane resin may be based on polyether alcohol and a diisocyanate to which an organic filler is added so that the body adheres to the olefin copolymer layer. Alternatively, the polyurethane or epoxide body may be bonded to the layer by an intermediate adhesive layer. The adhesive is (1) based on butadiene acrylonitrile copolymer mixed with a chlorinated diphenyl resin to which is added a 5-10% solution of triphenylmethane-4,4<SP>1</SP>,4<SP>11</SP> triisocyanate in a 20% methylene chloride solution; (2) long chain polyester alcohols in admixture with isocyanates, e.g. 10% of triphenyl- 4,4<SP>1</SP>,4<SP>11</SP>  -  isocyanylnonosulphophosphate in a 20% methylene chloride solution; (3) based on ethyleneacrylic acid or cyanoacrylonitrile (for polyurethane bodies only) copolymers forming a 10-15% solution in xylene heated to 70-80‹ C. The adhesive is brushed on to the olefin copolymer layer and the solvent is evaporated. For epoxide resin bodies, adhesive (3) is applied, during the cross-linking or vulcanizing process. evaporation being effected by the process itself. Another adhesive for epoxide resin may be (4) a solution of ethylene-vinylacetate copolymers.
