Title: Pigmentation of thermoplastic filament-forming polymers
IPC: C08J3/20
Filed: 1961-08-30
Abstract: A process for pigmenting a thermoplastic filament-forming polymer, comprises dry blending powdered polymer with pigment and then centrifugally milling (grinding) the mixture to disintegrate pigment agglomerates and disperse same throughout the polymer. The pigmented polymer may then be fused, with or without additional polymer, and shaped e.g. to filaments or fibres.  The milling may be by centrifugally propelling of mixture against a series of rotating pins.  In examples polypropylene is pigmented with (I) carbon black, and (II) Monastral Blue.

Title: Improvements in or relating to rope or like coiling machines
IPC: B66D1/36
Filed: 1921-11-29
Abstract: 189,348. Elliott, A., and Elliott & Garrood, Ltd. Nov. 29, 1921. Coiling. - A machine for coiling rope &c. is fed with the rope by a winch and lays it in superimposed layers which are non-circular, thus preventing the rope from becoming tangled. The rope is received by a pulley 18 on a sleeve 16, which can be connected by a friction clutch 19 to a shaft 10 driven by a chain 11 from the winch. The rope passes through a sleeve 32 to a guide 28 carried by an extension 30 of a wheel 27, which is alternately accelerated and decelerated, although the speed of rotation of the shaft 10 is constant. A gear .17 on the sleeve 16 drives an annular gear 20, within which is eccentrically mounted a vertical spindle 22 carrying a gear 26 meshing with the wheel 27. A pawl 24, pivoted on the spindle 22 and extending radially across the upper face of the gear 20, is engaged by one of a number of crown-teeth 25 thereon, and imparts the varying angular velocity to the wheel 27. The back of the teeth 25 are sloped so as to provide an overrunning ratchet gear for the rope guides. In order that a rope, the end of which is not available. can be inserted in the guide, the wheel 27, its bearing 31, and the sleeve 32 are slotted to form a passage, through which the rope may be passed. The sleeve 30 is rotatable through a suitable angle so as to bring the slot into or out of alignment with the slot in the bearing 31, and it is provided with a handle to lock it in position. A jockey-pulley 38 carried by a spring-restrained lever 39 pivoted at 40 co-operates with the pulley 18 and is retracted therefrom by a lever 43 having a tooth 45 bearing against a cam-surface 46 on the lever 39. The machine may be used in conjunction with that described in Specification 188,968, [Class 78 (v), Winding and paying-out apparatus &c.].

[Class 100 (i)] Sheets are fed to a printing-machine in overlapped condition by tapes 7 which direct the sheets to a feed board 5, and the sheets are registered longitudinally by combined registering and scraping devices 20 mounted on an oscillating shaft 21. Each scraping device comprises a radial arm 20a which as the shaft 21 moves clockwise from the position shown in Fig. 3, engages the front edge of the sheet 7b arranged below the foremost sheet 7a which, as shown, is fed to the grippers 4 of the cylinder 1 of a rotary offset press by means of grippers 23 carried by oscillating arms 24, which may be fitted also with an additional registering device 29, Fig. 2 (not shown). To the arms 20a are secured scraping devices 20b having inclined edges 20c which are moved across the lower side of the sheet 7a to detach the sheet 7b therefrom, and the device 20b also acts to smooth the sheet in conjunction with the board 5. The lifting of sheet 7a permits side registration of sheet 7b to be effected by sucker or other gripping devices. The shaft 21 may be mounted in adjustable bearings. Specification 657,617 is referred to in the Provisional Specification.

Title: Transparent polyester resin-bonded glass fibre material
IPC: C08K7/14
Filed: 1954-11-04
Abstract: Transparent plastic material is produced by a process comprising embodying a mass of glass fibre in an uncured resin and curing, wherein the resin is derived from a mixture of (a) the reaction product of a dihydric alcohol with an unsaturated dicarboxylic acid or an ester-forming derivative thereof and (b) a copolymerizable monomeric component comprising styrene, and wherein the uncured resin has a refractive index less than that of the glass by an amount in the range 0.019 to 0.025.  The resin may be derived from the usual constituents and optionally may be modified with conventional ingredients.  In the examples, 10 mols. maleic anhydride and 11 mols, dipropylene glycol are slowly heated under nitrogen to 200 DEG  C. and maintained at this temperature for 3 hours, cooled to 80 DEG  C. and dissolved in styrene monomer to give a viscosity of 200 cp. at 25 DEG  C., 300 parts per million t-butyl catechol being added, resulting in resin A.  Resin B of the same viscosity is similarly prepared from 5 mols. maleic anhydride, 5 mols. phthalic anhydride, and 11 mols. propylene glycol.  2 parts by weight of resin B and 1 part by weight of resin A catalysed with benzoyl peroxide is poured on to a regenerated cellulose sheet and a glass fibre mat of refractive index 1.549 is placed on it, and after soaking, more resin is poured on to the mat when it is then covered with a second regenerated cellulose sheet, rolled to remove air and pressed to one-sixteenth inch at 220 DEG  F., producing a sheet with a transparency of 55 per cent.  A single resin employing the same proportions of acid anhydrides and glycols manufactured in a similar manner produces a sheet with a transparency of 42 per cent.  The products may also be formed into articles such as bows, arrows and fishing rods.

[Class 59] In a jaw-crusher comprising two stationary jaws facing one another, two co-operating swinging jaws are operated by a single pitman to move simultaneously toward the fixed jaws and a stabilizer device -is provided which takes the thrust due to the difference in pressure exerted by the crushing jaws. The driving shaft 3 has an eccentric portion 4 encircled by the upper end of the pitman 6. The pitman has at its lower end a slot 11 accommodating a block 12 pivotally mounted on a shaft 13. Renewable wearing plates 17 are provided in the pitman, making sliding contact with the block 12, and lubricating passages are indicated at 46. Motion is transmitted to the swinging jaws 19 by suitable toggles 18 which may bear against the pitman at any suitable position slightly above or on the horizontal centre line of shaft 13. Means for returning the swinging jaws comprise pins 22 extending through the jaws and through slots 23 in the frame, being acted on by springs 27. The stationary jaws 29 have convex working faces 29a of relatively small uniform radius while the swinging jaws have concave working faces 19a of relatively large uniform radius, and the jaws are so arranged relatively to each other that there is formed between them a crushing chamber 25 of curved formation which is such that a stone cannot be nipped between the faces above approximately the mid-point of the depth of the chamber. The jaws 29 are held in position by laterally extending wedge-shaped bars 32, while similar bars 19c hold the renewable plates 19b which form the working faces of the swinging jaws. The jaw plates 19b or 29 may thus be removed and inverted. Each swinging jaw 19 is suspended from a transverse spindle 37 which oscillates in eccentric bushes 38, Fig. 4, secured in brackets 39 by caps 40. The bushes 38 may be provided with teeth 42 co-operating with teeth 43 in the caps 40 to hold them in adjusted position.
