Abstract: 909,843. Manoazo dyes containing ester groups. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 30, 1959 [Feb. 10, 1959], No. 4687/59. Class 2(4). The invention comprises water-insoluble dyes of formula where D is a mono- or bi-cyclic aromatic nucleus, R is a lower alkyl or aralkyl group, either of which may carry substituents other than sulphonic or carboxylic acid groups, or for the group -A-COOA<SP>1</SP>-(X) n , A is CH 2  or C 2 H 4 , A<SP>1</SP> is a saturated di- or tri-valent aliphatic radical of 1 to 4 C atoms, X is a cyano, lower alkoxy, carbo (lower alkoxy), carbonamido, acyl, acyloxy, acylamido, amino, alkyl- and dialkyl-amino and monocyclic aryl radical, n is 1 or 2 and D and E may carry substituents other than sulphonic or carboxylic acid groups. "Lower" relates to groups of not more than five carbon atoms. The dyes may be made by coupling appropriate diazo components corresponding to D with the required azo component, or by condensing a dye containing a group -A-COOH, instead of -ACOOA<SP>1</SP>(X) n , with a halo compound Ha-A<SP>1</SP>-(X) n  where Ha represents a Cl or Br atom. Condensation is effected by heating in the presence of a base and a solvent. When X is an acylamino radical the dyes may also be made by acylating the corresponding dye in which X is an amino group. D is indicated as being a benzene, naphthalene, thiazole or benzthiazole residue and may contain substituents, e.g. nitro, cyano, thiocyano, methylsulphonyl, trifluoromethyl, sulphamyl and halo groups. Indicated as substituents for E are halo, alkyl, alkoxy, acylamido and trifluoromethyl groups. Representative of specified values for R are methyl, cyanoethyl, carbethoxyethyl, carbonamidoethyl and p-nitrobenzyl. Indicated for A<SP>1</SP> are CH 2 , C 2 H 4 , CH 2 CH 2 CH 2 , CH 2 CH 2  CH 2 CH 2  and -CH=. Representative of specified values for X are ethoxy, carbethoxy, methylcarbonyl, acetoxy, acetamido, diethylamino and p-nitrophenyl. The dyes colour artificial textile materials, e.g. cellulose acetate rayon, cellulose triacetate and polyester fibres, orange to blue shades being obtained. The dyes are preferably used in a dispersed form. Dyes wherein X is a carboalkoxy, and especially a cyano group, have exceptionally high affinity for aryl polyester textile materials. Dyes wherein D is a pnitrophenyl nucleus, which may be further substituted, have excellent fastness to light and those where D is a 2-benzthiazyl nucleus have particularly good fastness to dry heat treatments. Numerous examples are given of the preparation of .the dyes and their use in dyeing processes. Specifications 844,784 and 859,899 are referred to.

Title: Connection system for electric transformers
IPC: H01F38/24
Filed: 1921-02-12
Abstract: 159,136. Campos, G. Feb. 12, 1920, [Convention date]. Transformers.-In transformer systems for feeding indicating or measuring apparatus, such as voltmeters, the tension between any two conductors or between a conductor and the ground is distributed over two or more transformers whose primary windings are connected in series in order that the effects of a short-circuit in one of the transformers may be moderated by the impedance of the remaining transformers. Fig. 1 shows an arrangement for measuring the voltage across a single-phase line 1, 2, in which two transformers T1, T2 are employed with the primary windings connected in series with the voltmeter V. A similar arrangement, with pairs of transformers in series, may be used with a threephase line. The magnetic circuits of the transformers may be entirely independent of each other, or the transformers may be linked together on a core of the form shown in Fig. 4. In the Specification as open to inspection under Sect. 91 (3) (a), the invention is not limited to transformers feeding indicating or measuring instruments, and the following arrangements are also described. For a three-phase system, threestar-connected transformers may be used, each of which exercises a protective action on the others. Fig. 4 (Cancelled) shows the application of the invention to a three-phase line 1, 2, 3 with a neutral or earthed conductor n. The primarywindings of the transformers T1, T2, T3 are connected to the lines 1, 2, 3 and to a star point which is connected to the neutral conductor n or to earth through a further transformer Tn. The transformers may have independent cores or a single core with four branches may be used. This subject-matter does not appear in the Specification as accepted.

Title: Automatic circuit breakers
IPC: H01H71/56
Filed: 1962-02-09
Abstract: 1,000,486. Automatic circuit - breakers. FEDERAL PACIFIC ELECTRIC CO. Feb. 9, 1962 [Feb. 17, 19611, No. 5081/62. Heading H2B. In a circuit-breaker, a spring contact-closing mechanism includes a pair of links 170, Fig. 5, pivoted to each other at a " knee " 172, and springs 142 acting on the ends of the links so as to bias the ends of the links towards each other, the links being arranged to move from an extended position to a collapsed position, Fig. 5, so that maximum thrust is exerted at the end of the closing stroke. The knee 172 is connected to the contact operating linkage through a pin- and-slot lost-motion connection 128, 180, Fig. 3, to permit the springs to be recharged whilst the contacts remain closed. In Fig. 3, main contacts 34, 36 and arcing contacts 46, 66 are held closed by an overset toggle 70, 104 extending between contact arm 30 and a latch lever 80, the over-centre movement being limited by an operating lever 124 abutting an adjustable stop 130. On the operation of an undervoltage release or, as shown, an overcurrent release 27, a latch 100 is turned to release a latch prop 90 which turns to release the latch lever 80. This permits the toggle 70, 104 to collapse under the bias of springs 118. As the contacts open, shock-absorbing resilient rollers 112 engage cams 114 on frame members 85 to guide the opening movement of the operating linkage so that springs 94 and 102 are able to reset the latch 100 and prop 90, the linkage moving into the position shown in Fig. 2. Closing of the contacts is effected by the spring mechanism turning the operating lever 124 about its fixed pivot 82 to cause a link 122 to straighten the toggle 68, 104. The springs 142 are charged by turning cams 184, Fig. 5, clockwise, the cams acting on pins 158 carried by thrust members 150 on which the links 170 are pivoted at 160. When the springs are fully charged, Fig. 12, further movement of the cams to release the springs is prevented by a projection 192 engaging a stop 190 and from which it is released on the operation of a " closing " push-button 218, Fig. 2. The cams 184 may be turned to charge the springs 142 by an electric motor 220 operating through a gear-box 230, Fig. 2, a cam 234, Fig. 11, a drive member 228, a pawl 240 and a ratchet-wheel 222. Alternatively, the cams may be turned by manually rotating a lever 252 in one direction to engage the teeth on members 225, 258 of a clutch 226 and then turning the lever 252 in the other direction to turn the cams 184. A manual trip button 288 is housed in the hub of the lever 252 and through pivoted member 296 operates a rod 298 acting on the latch 100. The circuit-breaker disclosed is a three-phase circuit-breaker in which the respective contact arms 30 are coupled by members 70 to a common bar 68 for operation by a single operating linkage and closing mechanism.
