Title: Process for colouring plastics
Inventor: HUGGILL HENRY PERCY WYNNE
IPC: C08K5/00
Filed: 1950-12-22
Abstract: Plastics are coloured by admixing therewith copper octa-(4,5)-phenyl-phthalocyanine, (see Group IV (c)).  The mixing may be carried out by masticating while heating, if desired in presence of liquids such as alcohol, water or acetone.  Plastics specified are polyethylene, polystyrene, acrylate resins, cellulose esters and ethers, phenol- and urea-formaldehyde condensates.  A lacquer may be obtained by mixing the phthalocyanine with a solution or suspension of the plastic material.  White pigments, e.g. titanium dioxide, may be present. In examples, copper octa-(4,5)-phenyl-phthalocyanine is mixed with (1) cellulose acetate and dimethyl phthalate, and (2) paper pulp, a urea-formaldehyde condensate, zinc stearate and triethyl phosphate, in each case with or without titanium dioxide. Also in examples, (3) a white lacquer comprising a urea-formaldehyde resin, a non-drying oil alkyd resin, xylene, butanol, and titanium dioxide is mixed with a suspension of the phthalocyanine in a similar lacquer not containing titanium dioxide.ALSO:Copper octa-(4.5)-phenyl-phthalocyanine is made by heating 4.5-diphenylphthalic acid with urea and cupric chloride in suspension in monochlonraphthalene in presence of ammonium molybdate and boric acid.  It may be used for colouring plastics (see Group IV (a)).

Abstract: 875,305. Sewing-machines. SINGER MANUFACTURING CO. Sept. 14, 1959 [Sept. 16, 1958], No. 31281/59. Class 112 The thread case carrier 4 of a rotary book has mounted within it a thread case 7, having a side wall 9 and a top wall 8, arranged to receive a cop of thread which does not include a bobbin. The thread case 7 is secured in the carrier by the engagement of one end 21 of a latch 19, which is slidably mounted on the top wall 8, with an aperture 22 in the carrier. The latch may be withdrawn, to remove the case, by the camming action of one end of a lever 26, pivoted at 27 to one end of the latch, against the edge of an aperture 29 in the wall 8. This withdrawing movement is limited by the engagement of a stop 30 with one end of a slot 31. An elongated pin 33 mounted on the latch moves from a slot 32 in the side wall, as the latch is withdrawn, to engage the thread cop and hold it within the case as the latter is withdrawn. The angular relationship between the thread case and the carrier is fixed by the co-operation of a stud 17 on the carrier wall with a slot 18 in the side wall 9. To prevent the thread case rattling in the carrier during operation of the hook the carrier has a pair of spaced apertures (see Fig. 5, not shown) through which the ends of a leaf spring extend into engagement with the periphery of the thread case.

Title: Improvements in or relating to three-phase transformer or choking coil arrangements
IPC: H01F27/38
Filed: 1937-11-24
Abstract: 506,280. Transformers and inductances. SIEMENS-SCHUCKERTWERKE AKT.-GES. Nov. 24, 1937, Nos. 32416 and 32417. Convention dates, Nov. 24, 1936 and Feb. 27, 1937. [Class 38 (ii)] To suppress harmonics such as the 5th and 7th in a 3-phase transformer or choking coil, the arrangement is such that three or more 3-phase flux systems of fundamental frequency are produced which are displaced by angles alpha1, alpha2, &c. with respect to each other and in which the vectors polygon formed by the fluxes multiplied by the associated magnetising force and iron path length and displaced through Kalpha1, Kalpha2, &c., where K is a number divisible by 6 and lying between two adjacent odd harmonics other than the third and multiples thereof, is closed. As shown in Fig. 3 each limb of a three-phase core is split into three sections by slots and the main fluxes in those sections produced by the main winding 1 are displaced with respect to each other by means of auxiliary windings 2, 3, 4, 5 connected in star and delta. These auxiliary windings arc dimensioned to force a phase displacement of e.g. 20‹ The arrangement is designed so that the voltages produced in the main winding when phase displaced by the phase angle multiplied by the number divisible by six nearest to the harmonic form a closed polygon. In a modification, instead of a slotted core, three cores arranged side-by-side are used. In a further modification shown in Fig. 9 each core limb has a single slot, the three-phase displaced fluxes for each phase being comprised by Ua, Ub and Uc. In a modification of this the slots are arranged at the comers of the core. A further modification is shown in Fig. 15 in which the flux division is obtained by slotting the yoke, the three groups of three phase fluxes being U, V, W; Ua, Va, Wa and Uc, Vc, Wc, of which Wa and Wc each have two components. In a further modification the three sets of three-phase fluxes are obtained by means of three single-phase three-limbed cores. Fig. 24 shows an arrangement in which four sets of three-phase fluxes are obtained. The core is formed by two sections, each limb being slotted so as to form for each phase 4 elements a-d. A further modification is shown in Fig. 25 in wh:ch the four fluxes a-d per phase is obtained by double slotting each limb. In a further modification a four-flux system s obtained by means of a five-limb core with the three main limbs slotted, the fourth set of fluxes being formed by the fluxes in the outer limbs and yokes. A further modification is shown n Fig. 32 in which three groups of fluxes are obtained by slotting the yokes, orie yoke having two slots. Various connections of auxiliary windings for flux distribution are described. Short-circuited conductor bars 25, 26 which may be folded over as shown at 42, Fig. 37 may be provided to reduce leakage across the slots.

Abstract: 1,194,721. Strap straining tools. THOMAS & BETTS CORP. 14 July, 1967, No. 32540/67. Heading F2G. A strap tightening and cutting tool comprises an axially movable and rotatable shaft 23, Fig. 1, and a slidable cam element 31 in a housing 20, a cam follower 27 biased against the cam element and secured with limited axial movement on the shaft 23 and a lever 32 for causing axial movement of the shaft and cam element to apply a tensile force to a strap secured to the shaft which overcomes the force applied by the cam follower biasing means to cause axial and angular movement of the cam follower thereby rotating the shaft and strap. Operation.-Strap 41 is inserted through members 38, (48), (52), Fig. 5 (not shown), and is held by a spring-loaded pawl 42. Movement of handle 32 towards handle 63 draws the strap inwardly and a spring 25, acting through pin 27, cam 31 and pin 35, returns the shaft to the left with the pawl 42 moving freely along the strap. Repeated operation draws the strap progressively into the tool until the resistance offered by the strap overcomes the spring 25 so that further movement of the handle 32 causes the shaft 23 to rotate due to the action of cam surface 64. Twister head (48) of plate 47 rotates the strap 41 from its initial position against the cutting edge (59) so that the knife blade (51) moves until it abuts stop (60) whereafter the strap is cut. The initial engagement of the strap 41 with the blade 51 impales it on a serrated edge 54 to retain it in position during cutting. On return of the shaft to its original position the twister head is rotated counterclockwise (in Fig. 5) and the blade (51) is returned to its original position by engagement of the recessed portion 56 of the twister head with a protuberance 57 of the knife 51.
