Title: Polymer purification
IPC: C08F10/00
Filed: 1962-09-26
Abstract: Polymers of a mono-olefine dissolved in a non-polar solvent are purified by emulsifying in the solution a small amount of a polar liquid immiscible with the solution to form a discontinuous phase, and subjecting the emulsion to the action of an electric field so that a substantial proportion of the impurities migrate to the polar liquid and the polar liquid droplets coalesce to a second continuous phase, and separating the second continuous phase and impurities from the polymer solution.  The "polar liquid" may be water, glycerol or ethylene glycol.  The "non-polar" solvent is preferably a C3 to C12 hydrocarbon.  The olefine may be ethylene, propylene, butene-1, 3-methyl butene-1, pentene-1, or 4-methyl pentene-1.  In the example the impurities removed arise from a chromium oxide catalyst supported on a carrier consisting of silica and alumina.

Title: Improvements in or relating to travelling hoppers or the like particularly for use with sintering apparatus
IPC: F27B21/06
Filed: 1929-12-07
Abstract: 340,738. Feeding devices for granular &c. materials. GREENAWALT, J. E., 110, East 42nd Street, New York, and ALEXOVITS, T. M., 91, Broadway, Bayonne, New Jersey, both in U.S.A. Dec. 7, 1929, No. 37589. [Class 59.] Relates to a travelling hopper or charge car adapted to deliver material as it travels and is applicable more particularly for charging sintering pans. The car is moved on its rails 5 by means of its power-driven track wheels and carries two hoppers, one 12 for fine the other 12<1> for coarser material. Each hopper has a delivery roll 21 and a gate 48, and, in the case of the " fines " hopper, a spreader 54 and a roll 55 for breaking up any cohering masses. This mechanism is automatically put in operation and again stopped at the points necessary for discharge into the pans by means of a cam rail 78, Fig. 2, adapted to engage a roller 34 on the lower end of a rod 27 suspended from the short arm of a lever 25 loosely mounted on the shaft of the delivery roll, and carrying a gear wheel 31, which, when the roller 34 is raised by the cam rail, becomes a drive connection between a pinion 10<1> on the track wheel axle and a pinion 24 on the delivery roll shaft. The axial movement of the cam roller necessary to put it into position to engage the cam rail is effected by a hand-lever 40 which can be latched in operative or inoperative position. Thus the delivery roll 21 is put in motion only when the hopper is over the pan. The rod 27 in addition to being connected to the lever 25 for the purpose of throwing the delivery roll into and out of operation is connected also to an arm 45 of a balanced rock shaft 46 carrying the hopper gate 48 which is thus opened only when the delivery roll is in motion. The breaker roll 55 is driven by sprocket gearing from the forward track axle through a hand-controlled clutch. The spreader 54 is carried by swing arms 53. The amount of hopper opening is determined by a vertically adjustable plate 14 forming the upper edge of its mouth. In a modification the two cam track rollers are controlled by a single lever.

The transfer image process of Specification 905,700, which employs a photopolymerizable material of the kind disclosed in Specifications 741,294 and 741,441 comprising a thermoplastic organic polymer and a compound containing terminal ethylene groups and capable of forming a high polymer by photo-initiated addition polymerization and having a plasticizing action on the thermoplastic polymer, is modified in that instead of the underexposed and still thermoplastic areas of the exposed sheet of photopolymerizable material being transferred on heating to a receiving sheet, the exposed sheet is placed in contact with a surface comprising solid disjunctively-transferrable effect material, whereupon on heating and then separating the sheet and said surface the effect material is transferred to the underexposed areas of the photopolymerizable sheet. By placing the sheet bearing imagewise the effect material in contact with a receiving sheet, heating to a temperature at least equal to the transfer temperature of the thermoplastic polymer and separating the sheets an image comprising effect material and thermoplastic polymer is transferred to the receiving sheet. Several copies may be made by repeated transfer from the exposed photopolymerizable sheet bearing the effect material. The effect material may be dyes, thermally activated colour-forming reactants, e.g. as in Specification 905,699, powdered pigments, or hydrophobic or hydrophilic materials temporarily adhering directly to a support or dispersed in a binder for this purpose, or thin metal layers. The process may be used for not only the production of prints but also in the preparation of printed circuits, lithographic printing plates and in the production of spirit copying masters and silk screen stencils.

To simplify the marker in a marker controlled switching network over which two-wire and four-wire paths are switched, the four-wire paths are set up as two separate two-wire paths established one after the other. As shown, incoming two-wire circuits EZ are served by a marker M over connector AK1, the marker receiving digits to determine which group of outgoing two-wire circuits FZ is required and setting up a connection from the calling EZ to a free one of the wanted FZ The marker controls the network over connector AK2. A calling four-wire circuit EV signals the marker to indicate the nature of the connection required by operating relay X. Each four-wire circuit is allocated two inlets to the network which inlets may or may not be adjacent but will be distributed according to a scheme. The marker in response to digits received connects one inlet to a corresponding outlet of a four-wire circuit FV in the wanted direction. Once that connection is made the marker proceeds to set up the connection between the other pair of corresponding inlets and outlets, the corresponding pairs of outlets allocated each outgoing four-wire circuit being adjacent or being distributed in the manner of the four-wire inlets.
