Title: Improvements in electric protective arrangements of the earth leakage type
IPC: H02H7/22
Filed: 1941-08-13
Abstract: 549,500. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., TRENCHAM, H., and MORTLOCK, J. R. Aug. 13, 1941, No. 10282. [Class 38 (v)] [Also in Group XXXVI] An arrangement for giving warning of or protecting against the deterioration of the insulation of a section of metal-enclosed conductor, such as a busbar, comprises insulating the metal sheath of the conductor from earth and utilizing the current flowing to earth through the resultant capacitance to modify, after rectification the impedance of an A.C. reactor, the alternating current flowing through which is used for operating a detector. The insulation between the three-phase conductors A .. C and sheaths is denoted by condensers A1 .. C1 the lower plates of which are connected together and to earth through rectifier R arranged to supply a winding D of a reactor E, the winding F of which is in an A.C. circuit containing a relay G. Deterioration in the insulation of Al or B1 or Cl will cause a larger current to flow in coil D and so lower the impedance of the reactor sufficiently to permit operation of the relay. Greater sensitivity can be obtained by replacing the relay G of Fig. 1 by a similar arrangement of rectifier R1 and reactor E1, the relay G1 being similarly arranged in the cascaded circuit, Fig. 2. Alternatively or additionally, the circuit of G can include a bridge-rectifier the output of which supplies a further winding on core E so as to amplify the change in impedance of coil F, Fig. 3 (not shown). In Fig. 4 (not shown) a condenser is in the relay circuit so as to resonate at certain conditions of the current flow in winding D. In Fig. 5, two sets of conductors have the outputs of their rectifiers R, Rl, connected to balancing windings D, D1 on the reactor El, normal out-of-balance being compensated by rectified current fed to a coil K. A condenser L in the circuit of coil F is shunted by a rectifier R1, the output of which supplies an amplifying winding H, a small change in the reactance of F increasing the volts across L and hence the current through H which further diminishes the reactance of F and ensures operation of the relay G. The arrangement shown in Figs. 3 and 4 of Specification 549,470 may be applied to the present arrangement for determining the faulty insulation Specification 541,419 also is referred to.

[Also in Group XXXV] An eddy current coupling has three members 5, 6, 7 concentrically mounted, the member 5 being the driving member while the members 6, 7 are the driven members, at least one of the said three members is provided with a field system which cuts the surface(s) of the other member(s) in which eddy current may be induced. The said field is selectively directed into either of the other members in order to transmit power selectively to the driven member 6 or 7 from the driving member 5. Fig. 1 shows an irreversible prime-mover 1 which can drive the power shaft 2 in either direction through the three-member eddy-current coupling 3 and a gear system 4. The members 6, 7 are respectively connected with concentric outer and inner shafts 8, 9. The outer shaft 8 carries a pinion 10 which meshes with a gear wheel 11 on shaft 2. The inner shaft 9 carries a pinion 12 which meshes with pinions 13, 13' on lay shafts 14, 14' carrying a pair or pinions 15, 15<SP>1</SP> which in turn mesh with the wheel 11. Thus transference of power in either direction can be effected by the selection of the correct driven member by energizing one of the respective field systems 6, 7. The same result can be achieved by arranging the field system on the driving member 5 by employing salient poles on the inner and outer surfaces of the member 5. Specification 288,329, [Class 35], is referred to.

Preferably, the process is carried out in the presence of a polymerization catalyst. Asymmetrical dichlor-ethylene is the preferred monomer and specified compounds with which the dihalogenated ethylenes may be copolymerized (or heteropolymerized) are methyl, ethyl, butyl, octyl, 2-nitro-2-methyl propyl, methoxyethyl, chloroethyl, phenyl, cyclohexyl acrylates and methacrylates, acryloand methacrylo-nitriles, acryl- and methacrylamides (or mono-alkyl substitution products thereof), methyl vinyl, methyl isopropenyl and phenyl vinyl ketones, diethyl fumarate and maleate, and methylene diethyl malonate.  Specified dispersing agents are monosodium dodecyl, cetyl, myristyl, stearyl, oleyl and acetoxyoctadecane sulphates; the sodium salts of sulphonated isopropylated naphthalene and of methacrylic acid/methyl methacrylate copolymers; sodium tetradecane-1 sulphonate; the triethanolamine salt of dodecyl sulphate; c-cetyl betaine; hydroxypropyl c-cetyl betaine; dodecyl trimethylammonium bromide; stearyl trimethylammonium bromide; the diethyl cyclohexylamine salt of cetyl sulphuric ester and tetramannitan monopalmitate. The preferred catalyst is hydrogen peroxide; others mentioned include acetyl benzoyl, dibutyryl, lauroyl, benzoyl, acetyl and succinyl peroxides, peracetic acid and sodium peroxide, peracetate, perborate, perchlorate and periodate. Air may be displaced by an inert gas, e.g. nitrogen, carbon dioxide, methane or helium.  The polymerization may be carried out in a batch or continuous process.  The polymer may be separated from the aqueous emulsion by spraying into a heated and/or evacuated chamber, by cooling below the freezing point of the aqueous medium, by addition of a lower aliphatic alcohol, e.g. methanol ethanol, or by adding to the diluted emulsion.  Electrolytes, e.g. sodium chloride and sulphate, hydrochloric and phosphoric acids, lead nitrate and acetate, calcium and stannous chlorides, and magnesium and aluminium sulphates.  The polymer may be washed with dilute caustic soda or ammonium hydroxide, and finally with alcohol. Before precipitation, heat stabilizers and/or plasticizers, e.g. dibutyl phthalate, tricresyl phosphate and dibutyl sebacate, may be added.  The polymers may be used for the preparation of plastics, fibres, foils, films and adhesives with or without the addition of plasticizers, stabilizers, fillers, pigments, dyes, softeners, natural or other synthetic resins.

The coil 6 is rotated at an adjustable speed of from one to twenty revolutions per second, and may be caused to come to a momentary rest at the point of maximum coupling with each of the coils 4, 5. The coils 4, 5 may be duplicated in order to increase the number of maximum couplings per revolution of the coil 6. A similar rotating-coil coupling may be used in a directive transmitter to couple the generating-valve to the aerial system, the coil being arranged so as not to couple both aerial circuits simultaneously.
