Patent GB-105356-A (GB)
IPC: H02H3/34
Abstract: 105,356. McColl, A. E. Aug. 17, 1916. Protective arrangements.-Threephase circuits are protected against faults to earth and faults between phases by means of a relay having two coils, one energized from the secondary of a transformer in one phase, and the other energized by the resultant current supplied from the intermediate secondaries of transformers in the other two phases. In the form shown in Fig. 1, a mechanical balance on the beam principle is obtained, under normal conditions, between the attraction due to the current in the relay coil b derived from phase C, and the attraction due to the current in the coil a which carries the resultant current of the reversely interconnected transformers in phases A, B. This resultant current is 1.732 times that in the coil b, and in order to ensure a balance between the magnetic forces on each side of the fulcrum, the turns on the coil b are made approxinately 1.732 times those on coil a, or the transformers in the phases, or the leverages of the cores, or the cores themselves may be proportioned to give the necessary balance. Disturbance of balance due to a fault closes the local circuit of a trip coil P. The circuit of one of the relay coils may be provided with a fuse F to afford timeelement protection on balanced overloads. In a modified construction, two balanced-arm .relays are employed each with an operating-coil on one side and a restraining-coil on the other, the balanced arms carrying contacts on the operating-coil side only. The operating-coil of one relay and the restraining-coil of the other are energized in series from the resultant current, and the other two relay coils are energized from the single transformer. The restraining-coils have 10 per cent. more turns than is required for a balance, or 10 per cent. more leverage or 10 per cent. larger cores, so as to give a 10 per cent. restraint. A construction employing electro-magnetic balance is shown in Fig. 4, in which the transformers on the phases B<4>, C<4> are not reversely connected; they supply the coil b<4> on the relay M, which carries also a coil a<4> having the same number of turns as the coil b<4> and supplied from the phase A<4>, so that the magnetic effects of the coils balance one another. On the occurrence of a fault to earth, the balance is disturbed, the armature K<4> is attracted and the trip circuit closed. Fuses F<1>, F<2> are connected in the closed circuit of the interconnected transformers on the phases B<4>, C<4>, and the fuse F<1> is short-circuited by the resistance R<1> so as to disturb the magnetic balance on the blowing of the fuse F<1> in the event of a fault between phases A<4> and B<4> or between A<4> and C<4>. In the event of a fault between phases B<4> and C', both fuses blow and the balance is disturbed. The armature K<4> may be dispensed with, and the trip circuit energized bv a secondary winding on the magnet, which, in this case, has a closed magnetic circuit.

In a rod or tube coupling comprising coupling- members such as a nut N and a fitting B, Fig. 4, engagement of which causes a coupling element C to be forced into sealing engagement with a rod or tube T, the element 12 comprises a ring 13 having a cutting edge 15, and a yieldable annular part 12 connected to the ring and abutting against the fitting B whereby pressure exerted by a shoulder 19 on the nut against a shoulder 18 on the ring 13 causes the edge 15 to bite into the tube T. As shown, the part 12 terminates at its forward end in an abutment 10 having sealing engagement with the fitting B, and the ring 13 terminates in a tail piece 14. On tightening the nut N to the Fig. 5 position, conical surfaces on the shoulders 18, 19 engage, the ring 13 is rolled inwardly, the edge 15 cuts into the tube and throws up a ridge R, the part 12 buckles and has sealing contact at 29 with the tube, the forward end of the tube T is squeezed into arecess 11, the tail-piece 14 buckles and a bevel 36 on the nut engages a bevel 35 so as to compress the tail-piece and lock the nut N. The face 23 of the abutment 10 may be knurled or embossed so as to embed in the face 22 of the fitting and may have a rib 40 to cut into the face 22. Various metals for the parts are specified, the element C being of harder metal than the parts T, B or having a hardened cutting edge 15 and rib 40. Dimensions are also given. In a modification. Fig. 10, for connecting a valve body V to a tube T, an element 12a interposed between a flange F and a ring 71 bolted together is in two parts joined by press-fitting, one part 70 being a hardened member and comprising a cutting edge 68 and a shoulder 18a.

The invention also includes as novel compounds products obtainable as above and having the general formula wherein R<SP>V</SP> is methyl or ethyl, R<SP>VI</SP> is a C 3  or C 4  alkyl group, R<SP>VII</SP> is a C 1  to C 10  substituted or unsubstituted hydrocarbon radical especially C 1 -C 8  alkyl, phenyl or chlorinated phenyl, B is a C 1 -C 4  alkylene radical, and y is 0, 1 or 2 provided that when B is C 1  alkylene, y is 0 and that when B is C 2  alkylene, R<SP>VI</SP> is a primary or secondary C 3  or C 4  alkyl radical. The dealkylating agent used in step (a) is suitably a nitrogen or phosphorus base, a thiolate or an inorganic salt and the alkylating agent in step (b) is suitably an alkyl halide, alkyl sulphonate, dialkyl sulphate, alkyl phosphate or trialkyl phosphite. Several dealkylating and alkylating agents are specified. It is preferred to carry out both steps (a) and (b) in the presence of a polar organic solvent. The products can be readily selectively oxidized to the corresponding sulphoxides or sulphones, e.g. by using chemical oxidants such as peroxides, e.g. aqueous H 2 O 2 , nitric acid, permanganates and bromine. When the alkyl group removed in the dealkylation step is the same as that introduecd by the alkylation step the two steps may be carried out simultaneously by use of an appropriate dehydrocarbylating agent the by-product of dealkylation functioning as the hydrocarbylating agent, the net result being isomerization of the starting O,O<SP>1</SP>-dialkyl ester to the O,S<SP>1</SP>-dialkyl ester. The products, especially the novel compounds of the above given formula have pesticidal properties and may be used in admixture with suitable carriers or diluents to provide pesticidal compositions.
