Patent GB-846155-A (GB)
Title: Improvements in or relating to the manufacture of monovinylacetylene
IPC: C07C2/38
Filed: 1957-11-05
Abstract: Monovinylacetylene is produced by the polymerisation of acetylene at 30-100 DEG C. in the presence of an anhydrous solution p  of cuprous chloride in an organic carboxylic acid amide containing the hydrochloride of an unsubstituted aliphatic mono-amine of not more than 6 carbon atoms, the molecular ratio of amine salt to cuprous salt being from 1 : 1 to 2-3 : 1, and removing the monovinylacetylene and unchanged acetylene when not more than 10 mol per cent. (based on total gaseous product) of divinylacetylene is formed.  The amide may carry substituents such as methyl or butyl on the nitrogen atom and may be a cyclic amide (lactam); it must be fluid at the operating temperature and preferably contains not more than 6 carbon atoms. Suitable amides are dimethylformamide, formamide, N,N-dimethyl-acetamide, 2-pyrrolidone, N - methyl - 2 - pyrrolidone, acetamide, diethylacetamide, propionamide, butyramide and 2-piperidone. Suitable amines include methylamine, dimethylamine, ethylamine, dipropylamine, butylamine and hexylamine.  Hydrogen chloride should not normally be added to the reaction mixture but such addition may be necessary at intervals to reactivate the catalyst when it is added in very small quantities, not more than 0,1 per cent at any one time.  The process can be performed continuously or in batch operation.  Dilute acetylene such as formed in the pyrolysis or partial combustion of hydrocarbons may be used provided that oxygen, hydrogen sulphide, mercaptans or other substances which would react with the cuprous chloride are removed.  Specifications 384,654 and 793,748 are referred to.

Title: Improvements relating to electrical metering arrangements
Inventor: RYDER CLIFFORD
IPC: G01R11/56
Filed: 1962-09-12
Abstract: 1,032,093. Electric metering arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 22, 1963 [Sept. 12, 1962], No. 34832/62. Headings G4D and G4H. Electrical pulses produced by an electricityconsumption meter at a repetition frequency dependent upon the power consumption are routed by timing switching means to one of a number of registers (counters) according to the tariff to be charged. Fig. 2 (not shown), shows an induction-disc-type meter driving a cam to close two contacts, alternately thus producing pulses on two lines alternately. These pulses go to whichever of the electromechanical registers is selected by the timing device through a corresponding two-way switch. When the register steps due to receipt of a pulse the corresponding switch switches over. Thus, if one of the cam contacts should remain closed, due to sudden cessation of consumption of electricity, the driving coil of the register will not remain energized. The time switch may embody a self-starting synchronous motor or a mechanism regulated by a clock escapement. Maximum demand indicators are associated with the registers and are of the Merz type in which a pointer driven by the register drives a second pointer, the first pointer being reset to zero every 30 minutes by a resetting time switch. Fig. 1 (not shown), shows a modification which dispenses with the said switches together with one of the two wires and one of the cam contacts. Fig. 3 (not shown), shows an embodiment similar to that of Fig. 1 (not shown), except that the pulses are produced when an electromagnetic relay is actuated by the operation of a transistor oscillator (described in Specification 1,031,562, which is referred to) which occurs when high frequency and feedback coils of the oscillator are separated by a slot in a disc driven by the meter. Fig. 4 (not shown), shows a modification similar to Fig. 2 (not shown), except that the pulses are produced by two arrangements of the type in Fig. 3 (not shown), i.e. two transistor oscillators actuated alternately by slots in the same disc. The registers may be of the pointer or cyclometer type.
