Title: Elongated polymeric articles
IPC: B29C55/02
Filed: 1966-06-02
Abstract: 1,141,989. Uniaxially oriented films. EASTMAN KODAK CO. 2 June, 1966 [24 Aug., 1965], No. 24531/66. Heading B5B. [Also in Division A4] An elongated polymer article having high tensile strength in the longitudinal direction is made by heat-stretching the article, the article while stretched being subjected to a heating source of such heat output density that the outer layer of the article melts whereas the inner core portion of the article attains a temperature below the melting point. Such articles may be in the form of filaments, especially of rectangular cross-section or in the form of film, sheet, strip or tubing. Articles of strip form may be used as strapping. Such articles may be composed of a polyolefin, especially polypropylene, a blend of polypropylene with up to 40% of a filler material which is polyisobutylene, talcum or ethylene/ propylene rubber, or of a polymer of a blend of propylene and styrene; other specified materials include polyethylene, polyallomer, polybutene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyesters, polyurethanes or blends thereof. Such articles possess high tensile strength in a single direction yet have substantially no tendency to longitudinal rupture. The effect of the process is simultaneously to orient the core portion of the article while meltdrawing the sheath portion of the article. Draw ratios of from 7 : 1 to 15 : 1 may be employed In a preferred method, a strip formed from a blend of polypropylene and up to 40% of a filler as specified above is subjected to heat-stretching whereby the core portion is heated to a satisfactory orientation temperature and becomes highly oriented while the sheath portion is heated to a higher temperature at which orientation will not take place. In apparatus as shown, a polymeric strip 2 is extruded from extruder 1 and quenched by cooling roll 3, (or alternatively a bath containing a cooling medium), and then passes over guide roll 4 and into the nip of roll pair 5 which may be driven or allowed to idle. The strip then passes through the combination drafting and melt drawing chamber 6, the inner surfaces of which are highly polished and contain sources of high watt density thermal radiation 6 e.g. quartz iodine lamps 8. Strip 2 is withdrawn from chamber 6 by driven roll pair 9, the speed of which is such that the strip is elongated to several times its original length. The treated strip 10 is wound up at 11. Fig. 2 illustrates the cross-section of the strip before treatment, and Fig. 3 illustrates the cross-section of the strip after treatment, showing the oriented outer portion and unoriented core portion.

Title: Improvements in indicating mechanism for flow meters and other like measuring instruments
IPC: G01F1/37
Filed: 1925-10-07
Abstract: 241,201. British Thomson-Houston Co., Ltd., (Assignees of Thompson, L. W.). Oct. 7, 1924, [Convention date]. Tell-tale apparatus.-In apparatus ior indicating small movements in which a field winding is connected through a measuring instrument to a source of alternating current, an armature is provided having a closed winding thereon which may be moved angularly with respect to the plane of the magnetic field produced by the field winding. The Figure shows the invention applied to the measurement of the volume of fluid flowing through a conduit. The leading and trailing pipes 24, 25 on opposite sides of a constriction 26 in the conduit are led to the spaces 12, 13 below and above a bell 10 connected by a rod 19 and lever 20 to an armature 30 upon which is wound a closed circuit of parallel coils 31. The field structure 32 is wound with coils 32 connected through indicating and recording ammeters 37, 38, an integrating watt hour meter 39, and a resistance 36 to a source 35 of alternating current potential. Secured to the lever 20 over the fulcrum is an arm 41 carrying vertically adjustable centering weights 42, while a counterbalancing weight 43 is also secured to the lever to balance the rod 19 and parts connected to it. A plate 44 with a cam surface 45 is secured to the weight 43, a pin 46 bearing on the cam surface being carried by an arm 47 pivoted on a knife edge 49 on a standard 50. Suspended from above the knife edge are arms carrying weights 52. Normally, the parts are in the positions shown in the drawing, the instruments indicating zero. When fluid is flowing in the conduit, the bell tilts about its pivot 9 and the rod 19 moving upwards depresses the link 28 and rocks the armature until the weights on the levers balance the pressure. A current is now set up in the armature winding which reacts on the field winding, decreasing the impedance and permitting a greater current to flow in the indicating circuit. The relation of the movement of the armature to the change of current follows approximately a straight line law. The difference in pressure on opposite sides of the constriction is proportional to the square of the velocity of flow, the cam 45 being designed to modify the movement of the bell to rock the armature according to a straight line law.
