Patent GB-580748-A (GB)
Title: Improvements in the manufacture of vinyl ethers
Filed: 1943-11-25
Abstract: Vinyl ethers, other than n-butyl vinyl ether, are prepared by contacting acetylene and an alcohol, other than n-butyl alcohol, with a potassium alkoxide dissolved or suspended in a medium consisting solely or mainly of a secondary or tertiary aromatic amine at a pressure not greater than 9 lbs./sq. in. and a temperature of about 150-250 DEG  C.  The reaction is preferably conducted in an oxygen - free atmosphere and in the presence of an N : N1 - diphenyl - p - phenylenediamine as antioxidant. The alkoxide used is preferably that of the alcohol undergoing reaction.  In the examples: (1) a mixture of a solution of potassium in iso-butyl alcohol and ethyl aniline, together with a little N : N1-diphenyl-p-phenylenediamine is placed in a reaction tower fitted with a fractionating column, a stream of nitrogen being passed through the tower.  The contents of the tower are heated and the nitrogen flow gradually replaced by a preheated mixture of iso-butyl alcohol vapour and acetylene under slight pressure.  The reaction products pass into the fractionating column and an azeotrope containing mainly iso-butyl vinyl ether separated from unreacted iso-butyl alcohol which is recycled.  The ether is purified by distilling over sodium.  The process may be rendered continuous by replacing the catalyst as it becomes spent.  (2) A solution of potassium in iso-butyl alcohol and diethylaniline with a little N : N1 - diphenyl - p - phenylenediamine, is added, in an atmosphere of nitrogen, to diethylaniline contained in a flask fitted with a stirrer and a stripping column.  The contents of the flask are heated and the nitrogen flow replaced by acetylene and iso-butyl alcohol.  Vinyl iso-butyl ether distils off.  (3) Acetylene and tetrahydrofurfuryl alcohol are passed with vigorous agitation through a mixture of potassium dissolved in tetrahydrofurfuryl alcohol and diethylaniline.  The product is fractionated and distilled over sodium.  The resultant vinyl tetrahydrofurfuryl ether may be polymerized with stannic chloride dissolved in petrol or with boron trifluoride/acetic acid complex.  (4) and (5) Vinyl ethyl and vinyl methyl ether are prepared respectively in the manner described in example 1, the solvents being diethylaniline and benzyl ethyl aniline respectively.  The process can also be applied to, for example, the preparation of the vinyl ethers of propyl, isopropyl and tert. - butyl alcohols.  Other specified amines which may be used as reaction media are methylaniline, dimethylaniline, diethyl o- and p-toluidines, benzylaniline and dibenzylaniline.  Specification 579,675 is referred to.

Title: Measuring device in the connecting line between two electric power stations working in parallel
IPC: G01R11/52
Filed: 1924-08-22
Abstract: 221,208. Landis et Gyr Soc. Anon. Aug. 30, 1923, [Convention date]. Special quantities, registering.-In the connecting mains between two supply stations working in parallel are arranged a single watt-hour meter and a single wattless-current quantity meter. The watt-hour meter contains a double counting-train 12, while the wattless-current meter contains two double counting trains 13, 14, the upper registering leading and' the lower lagging currents. For this purpose ratchet clutches 15, 16 on the two counting trains 13, 14 are thrown into or out of action by reversal of rotation of the main shaft of the wattlesscurrent meter. On the driving disc 10 of the watt-hour meter is a stop 11 which engages a pawl 3 pivoted to a lever 4 coaxially with its fulcrum, and moving between stops 5, 6 on the lever. A spring 7 controls the lever 4, which actuates a contact 1<1> by means of a rod 9. In circuit with the contact are electromagnets 18, which cause transfer of registration from the lower to the upper counters of each double train. Thus one set of counters of each train is in action when current is supplied by one station, and the other when current is received by the same station. The driving shaft of the wattlesscurrent meter is provided with worms actuating the double counting trains and either cut similarly, when the ratchet clutches act in opposite directions, or cut reversely, when the ratchet clutches act in the same direction, or the worms may be cut similarly and the ratchet clutches act in the same direction, reversal being effected by an additional gear-wheel. The invention may be applied to polyphase supply systems.
