Title: Recovering polymer from dilute polymer dispersions
IPC: B01D3/06
Filed: 1962-06-18
Abstract: Solvent is separated by evaporation from a dilute solution, suspension or slurry of a thermoplastic material, such as a polyolefine, polystyrene or polyvinyl chloride, by passing the solution through the tubes of a multitubular heat-exchanger, the shell of which is supplied with heating-medium at such a temperature that solvent is evaporated, the flow of solution through the tubes being stabilized (i) by recycling to the feed-line some of the concentrate withdrawn from the heat exchanger, or (ii) by submitting the solution to preliminary partial flash vaporization, and then introducing the mixture of vapours and solution into the tubes of the heat-exchanger. Capillary tubes may be provided at the entrance of the heating-tubes in order to assist in stabilizing the flow.  In an example, a solution of polypropylene in xylol, containing 8,6% polymer by weight, is preheated to 227  DEG C., a pressure of 108 p.s.i.g. being maintained on the solution by means of a motorized needle-valve operated by a pressure indicator controller.  After flashing to a pressure of 21 p.s.i.g., the vapour-liquid mixture is forced into the tubes of a vertical heat-exchanger.  Each tube has a ( 1/8 inch x 1 inch) capillary at the inlet.  The mixture of vapour and liquid is discharged into a receiver held at 4 p.s.i.g., and the vapour is withdrawn to a condenser.  The liquid, containing about 84% polymer, is pumped through a second heat-exchanger maintained at about 250  DEG C.; and molten polypropylene is discharged, together with xylene vapour, into a receiver at a pressure of 0,2 mm. Hg.  The molten polymer is extruded into a water bath; and the solid strands so obtained are cut into pellets.  Dichlorobenzene vapour may be used as heating-medium in the heat-exchangers.

IPC: A01K89/01
Filed: 1971-04-19
Abstract: 1302828 Fishing reel SHAKESPEARE OF ARKANSAS Inc 19 April 1971 [5 March 1970] 23346/71 Heading A1A [Also in Division F2] A shaft 55 of a fishing reel serves to transmit the cranking torque applied at crank 59 to two driving gears 65 and 70 by means of frictional engagement with drag washers 75, 66, 62. The torque transmitted from shaft 55 to gear 65 and 70 depends on the size of the washers and axial pressure applied on the gears and washers by the control 61 which serves to alter the pressure on the gear arrangement between the spring 82 and web 58. When torque is low, the first gear train operates, the torque being transmitted from crank 59, along shaft 55 to gear 70 by means of drag washers, to a first pinion 30 and finally to the flyer of a spinning reel by means of bearing washer 32 which is firmly held between flyer 26 and first pinion 30 by means of spring 50 and shaft 36. The second pinion 45 slides freely relative to pinion 30, the surface 88 sliding over surface 89, the pinions being held together by springed yoke 95. Above a predetermined torque, washers 66 and 75 are unable to maintain rigid connection between shaft 55 and gear 70 and slipping occurs; however stronger washers 62, 66 maintain rigid connection between shaft 55 and gear 65, and torque is transmitted from crank shaft 55 to gear 65 and so to second pinion 45. Torque is transmitted from pinion 45 to pinion 30 by means of the now engaging clutch surfaces 90, 91, while torque is transferred to flyer 26 from pinion 30 as before. The cam 118 serves to disengage second pinion 45, if desired, by pushing pinion 45 against the resilience of yoke 95 and freeing clutch pawls 40, 46.  In a modification the gear supporting shafts may be parallel. In a casting or trolling type embodiment, in which the drive and driven shafts are not parallel to one another, a spring is coiled around the second gear and connects to the first gear. With low torque, the first gear rotates with the second gear, the second gear being held by a spring. With large torques, the coil tends to unwrap, allowing movement of the second gear relative to the first gear. The rig 23, 25 driven by an eccentrically placed pin 94 on foot plate 58 serves to reciprocate line spool 21 and provide level wind.

Abstract: 1363327 Packaging by folding articles; folding paper E H AITKEN 18 May 1972 23396/72 Headings B8C and B8B [Also in Division D1] A device for folding flexible articles, e.g. fabric sheets, clothes, paper and flexible plastics materials, comprises belts 1, 2 for conveying an article in a first direction, belts 3, 4 following on from the belts 1, 2 for conveying the articles in a follow-on direction to the first direction, a fold station between the belts 1, 2 and the belts 3, 4, and means for reversing the operation of the belts 3, 4 when a predetermined length of article is located thereon. The device comprises six endless belts 1, 2, 3a, 3b, 4, 5 mounted in cantilever fashion on a wall 6 of a housing 7 containing the driving elements shown in Fig. 2. The belts are formed with toothed edges 11 which engage tooth rollers 12. The belts 3a, 3b have a slot 8 therebetween to accommodate a sensor arm 9 of an article sensing device 10. In operation, with an electromagnetic clutch 30, Fig. 2, disengaged so as to maintain a feed belt 14, Fig. 1, stationary, a motor 20, Fig. 2, is switched on to drive shafts 24, 33, 53, 29, 46, 38. Since no article is present on the belts, the sensor 10 disengages an electromagnetic clutch 49 and engages an electromagnetic clutch 41 to drive a shaft 42. Thus, the belts 1, 2, 3a, 3b, 4, 5 are driven in the direction of the arrows of Fig. 1. The article to be folded is placed on the belt 14 with the required fold line lying perpendicular to the length thereof. The clutch 30 is engaged and the belt 14 feeds the article between the belts 1, 2 which feed the article to the belts 3a, 3b, 4. The arrival of the required fold line at the gap between the belts is sensed by the leading edge of the article engaging the arm 9 at its preset position. The sensor 10 engages the clutch 49 and disengages the clutch 41 to reverse the gears 43, 44 and thus the direction of travel of the belts 3a, 3b, 4. A loop is thus formed in the article and further feed of the article causes the loop to pass between rollers 15, 16 of the belts 2, 4 and the folded article emerges between the belts 2, 5. If further folding is required, a second device is provided, e.g. as indicated at 2a, the lower run of the belt 5 carrying out the function of the belt 1. In modifications, (a) a positive fold forming device, e.g. a knife, is provided at the gap between the belts and the conveying path between the belts 3a, 3b, 4 and 1, 2 may be in a single plane; (b) the sensor 10 is of the photoelectric type; and (c) the sensing arrangement is provided in connection with the belts 1, 2 to sense the trailing edge of the article.

Abstract: 826,158. Centrifugal strainer separators. BRITISH WEDGE WIRE CO. Ltd. Aug. 22, 1957 [July 30, 1956], No. 23418/56. Class 46. Material to be centrifuged is introduced at o, Fig. 1, to the region between an inner member a, mounted on a shaft c and rotated by a shaft h through gears g,f, e, d, and a perforated basket i, mounted on a hollow shaft j and differentially rotated by shaft h through gears g, f, m, k. The filtering surface of the basket i is provided by panels of longitudinally-disposed, generallywedge-shaped wires q, Fig. 5, separated by tapered solid panels t, Figs. 1 and 5. The wires are located with their thicker dimension at the inside of the basket so that the spaces between the wires increase outwards as shown in Fig. 5. Each wire has spaced portions of circular cross-section where it is wound around rods s, Fig. 1, which secure the wires in the panels. The circular-section parts are thicker than the wedgesection parts so that the wedge-section parts of adjacent wires are spaced apart. Instead of wedge-section the wires may be of any section e.g.(T-section) such that the distance between adjacent wires at points outside the inside surface of the basket is greater than the distance between them at the inside surface. The upper portion of the basket is imperforate to absorb the initial impact of the material and thus reduce wire wear. The inner member a has external paddles b.
