Title: Polymerization of isoprene
IPC: C08F136/08
Filed: 1962-04-04
Abstract: High polymers of cis-polyisoprene are made by polymerizing isoprene in an inert hydrocarbon diluent with an organolithium catalyst and, reducing the induction period by heating the polymerizable mixture for a period of at least 5 minutes and at a temperature, e.g. 60 DEG to 110 DEG C., insufficient to convert more than one weight per cent of isoprene to the polymer, and then reducing the temperature, e.g. below 60 DEG C., and completing the polymerization.  The Specification contains a long list of catalysts.  The exemplified catalyst is lithium-methylnaphthalene.  The organolithium catalyst is generally formed in a polar solvent which is replaced by a hydrocarbon prior to incorporation in the polymerizable mixture. The polymer is recovered from the polymerizate by conventional techniques, e.g. addition of an alcohol, and an antioxidant.  The polymerizate prior to treatment for recovery of the polymer may be aftertreated to introduce functional groups such as -COOH, or -SH.

Abstract: 1527644 Removing defective blow moulded parts MONSANTO CO 1 April 1976 [2 April 1975] 13135/76 Heading B5A In a blow moulding process, Fig. 1, wherein an endless chain of rod assemblies continuously traverses an endless path around a pair of horizontal rotary turrets 14, 16, respectively at which a blow moulding preform is sequentially loaded on to each rod assembly, and moulding is effected by engagement of each rod assembly between hinged mould sections 76, 78, the fully blown articles are automatically discharged from the rod assemblies at a rotary turret station 24, at which underblown articles are sensed and their discharge prevented, for subsequent discharge at a station 10 located upstream of the turret 14. The drive of the turrets 14, 24, is effected from the moulding turret 16, by engagement of a sprocket wheel of each turret by an endless chain, the sprocket 36 of the turret 24, Figs. 7 and 8, carrying circumferentially spaced pockets 58 between which and a stationary guide rail 56 each article is engaged, for upward discharge of each fully blown article into a shoot 46. The discharge of each fully blown article is effected from each pocket 58 by compressed air admitted to a housing 92 of each rod assembly, via a valve 40 and a pipe 39 communicating through a further valve 42 and a radial passage of the sprocket 36. Each calve 42 is automatically actuated by a stationary cam 43 to permit passage of the air at the location of shoot 46, but the presence of an underblown article is detected by a photo-cell or mechanical means 62 carried by the rail 56, and which acts to prevent the supply of air through the valve 40. At the station 10, Fig. 5, the underblown articles are removed from the rod assemblies 20, by downward displacement of the preform carrying rod 63 therefrom, by means of a disc 96 of the rod 63 engaging a downwardly inclined ramp 98, and upward displacement of the underblown article by means 48 having opposed upwardly inclined rails which engage between the threads of the neck of the article, and deliver it laterally to a bin 72 via a laterally curved deflector 73.  The preforms comprise a closed end, and an open end which is moulded as a neck to drop around each rod assembly at the loading turret, from shoots which taper downwardly. The preforms and rod assemblies are enclosed within the mould section on the moulding turret, and moulding is effected by initially axial stretching the preform by extending the rod assembly, followed by blowing with air.

Abstract: 839,192. Electric follow-up, systems. PYNFORD Ltd. May 7, 1956 [May 10, 1955], No. 13514/55. Class 40 (1). [Also in Group XXXV] In a system for causing the position of a body to follow variations in the level of a conducting liquid, an otherwise stationary contact moved with the body forms with the surface of the liquid a switch controlling bias applied to an electronic valve which, in turn, controls the position of the body. In Fig. 2 if the level of the liquid E<1> rises to make contact with an electrode F<1> the negative grid bias of a triode valve N is reduced so that a relay S is energized to cause a reversible motor J<2> to raise a body H carrying electrode F<1>, until the electrode is withdrawn from the liquid. If, on the other hand, the level of the liquid falls to break contact with a slightly longer electrode F<2> the current through a triode valve P is increased so that a relay T is energized to cause motor J<2>, to. lower the body H until electrode F<2> is immersed again. The position of the body H is thus automatically adjusted to keep the level of the liquid between the ends of the two electrodes. Simplified systems employing only one valve and a non- reversible motor, suitable when the liquid level tends to change in one direction only, are described. Resitance-condenser networks or additional electrodes may be arranged to ensure a predetermined minimum extent of operation of the motor. Specification 778,913 is referred to.
