Title: Pigmented olefin polymeric material
IPC: C08J3/205
Filed: 1970-09-09
Abstract: 1306460 Colouring polyolefins MONTECATINI EDISON SpA 9 Sept 1970 [11 Sept 1969] 43066/70 Heading C3P Pigmented olefin polymers are prepared by introducing a polymer of an olefin or arylsubstituted olefin in the molten state into a liquid dispersion of a pigment and removing the liquid when the pigment particles dispersed in the molten olefin polymer have reached a size below 1 micron. Preferably the liquid is one which wets the pigment, and the addition of the liquid dispersion is effected during granulation or spinning. Specified olefin polymers are polymers of ethylene, propylene, butene-1, pentene- 1, hexene-1, 4-methylpentene-1, octene-1 and styrene, and propylene/ethylene copolymers. Specified pigments are azo pigments, phthalocyanines, vat dyes, lakes, titanium dioxide, iron oxide and carbon black. Specified liquids are water, alcohols and ketones. In examples dispersions of pigments in (1 and 2) methanol and (3) ethanol are added to polypropylene and dispersions of pigments in (4) methanol and (5) ethanol are added to polyethylene. The products may be spun into fibres or extruded into films.

Filed: 1936-05-09
Abstract: 474,622. Windings for dynamo-electric machines. BRAHAM; G. W. May 9, 1936, No. 13135. [Class 35] An armature winding for a rotary converter for converting three-phase current into unidirectional current or conversely consists of three groups of windings corresponding to the three phases for each pair of poles, corresponding groups being connected in parallel, and each group consisting of a number of sections corresponding to the commutator segments, the conductors of the sections of the same group lying in the same or adjacent slots and separate from the conductors of the other group ; the width of each section is equal to the pole-pitch and the commutator segments to which the conductors of a group are connected occupy two-thirds of a pole-pitch, the end segments of such a set being connected to slip rings. Fig. 4 shows such a winding for a four pole machine with 12 slots and 24 commutator segments. The conductors in the slots 1 and 4 forming one group are connected to the segments from a to b, and through those in the slots 7 and 10 to the segments from a<1> to b<1> as shown, the segments a and a<1> being connected to a slip ring x and the segments band b<1> to a slip ring y. The other conductors are connected as shown, commutator segments c and c<1> half way between the segments band a<1> and a and b respectively being connected to a slip ring z. The brushes p and q can be connected to auxiliary brushes p<1>, ql as shown. Arrangements for multiple windings are described, the conductors of the different windings being connected to alternate segments of the same commutator or to different commutators. Specification 454,022 is referred to.

Abstract: 551,562. Converting; phase shifting arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 15, 1941, No. 13282. Convention date, Oct. 17, 1940. [Class 38 (ii)] Relates to phase shifting arrangements and their application to the regulation of converters employing discharge devices of the immersion ignitor type and consists in a polyphase network of windings 29 arranged in auto-transformer connection to produce two opposing voltages E45, E46, Fig. 3, which are added vectorially to the voltage between the input terminals 49, 51, at least one of the voltages being variable to produce a phase shift of the output voltage. Regulation of the voltage components E45, E46 is effected by saturating windings 43c ... 48c on the cores of the different pairs of inductively coupled windings, the saturating windings being, in two groups which are simultaneously regulated in opposite senses by resistances 59, 60 controlled by a solenoid 61 or torque motor responsive to the D.C.. output voltage of the converter. Thus the two regulating voltage components are varied in opposite senses whilst the impedance of the network remains constant. The phase-shifter output voltage may be applied to the control electrodes 22 of the discharge devices 16 ... 19 through a further phase shifting network 68 also having two groups of saturating windings 25, 26 and 27, 28 energized respectively by load current in the two halves of the converter and arranged to maintain a balance of load therebetween. The converter shown is of the quarter phase type fed from a three-phase system 10 through a Scotttransformer 13, 14, 15, a similar transformer 42, 70, 71 being connected between the three-phase output of the phase shifting network 29 and the two-phase network 68 through which the ignition electrodes are supplied. The excitation circuits 40, 41 of the latter are as described in Specification 499,280.

Abstract: 133,429. Boys, E. J. Oct. 8, 1918. Hand-trucks.-Concrete blocks and the like are conveyed from the moulding-machine to the drying or setting racks by a truck which is adapted to pick up the base-plate on which the block is moulded. As shown in Fig. 1, the side frames of the truck each comprise a handle-bar 2, a hanger arm 5, and a frame bar 7. These side frames are mounted on the wheel axle on the outer sides of the wheels, and a shock-absorber 1<a> may be interposed. Hooks 6 on the arms 5 receive a bar 9 from which depend claws 8. By tilting the truck frame, these claws can be engaged with the base-plate 10 placed on the rails R on which the track runs. The plate 10, with the block 11 thereon, can then be transported to, and deposited on, the drying racks, which may be formed by extensions of the rails. In a modification, there is a single handle-bar only, eyes are substituted for the hooks 6, and a bar, upon which a counterweight is slidably mounted, extends from the bar 9 to the handle. According to the Provisional Specification, the truck may have a single wheel; moreover, the hanger arms may be resilient, and loading is effected by engaging the hanger arms with the bar 9, the truck being tilted for this purpose upon downwardly inclined arms which are brought into contact with the ground.

[Class 100 (i).] In apparatus for delivering products from printing-machines in counted batches, two or more receptacles each carried by a separate movable support are provided which move into position one after the other to receive a batch of products from a single delivery-fly. Each receptacle comprises a tray-like part 4, Fig. 1, carried by an arm 5 pivoted to a lever 6 mounted on a shaft 7. A toothed sector 8 fixed to the arm 5 meshes with a similar sector 9 on a lever 10 also mounted on the shaft 7. Rollers 11, 12 on the levers 6, 10 respectively run on cams 13, 14 on a shaft 15 coupled to the shaft of a delivery-fly 1. The motion imparted to the levers 6, 10 is such that the receptacle 4 moves downwardly gradually and parallel to itself as the products are delivered thereto from the fly 1. When the required number of products has been received, the receptacle 4 is lowered and the products deposited on a conveyor-band 25. At the same time the other receptacle 4 is tilted backwardly by relative motion between the gears 8, 9, so as to clear the downwardly-moving receptacle and is subsequently moved upwardly into position to receive the next batch of products. The drive for the conveyor 25 is such that the conveyor is at rest while each receptacle is delivering a batch thereto and comprises a gearwheel 16, Fig. 6, on the shaft 15 having a toothed sector 32 pivoted thereto engaging a gear 37 loose on the shaft 15 and fixed to a gear directly driving the conveyor. A roller 34 on the sector 32 runs on a fixed cam 35 and causes the desired speed variation.
