Patent GB-1106693-A (GB)
Title: Extension of latices
IPC: C08J3/21
Filed: 1965-05-04
Abstract: An aqueous polymer dispersion containing electrically-charge high polymer particles is mixed with a liquid which is compatible with the polymer and a surfactant capable of forming an emulsion of the liquid in water, the particles of said liquid and surfactant having a charge opposite to that on said polymer particles, and the resultant dispersion is maintained for a time and under temperature and pressure conditions sufficient to ensure thorough penetration or impregnation of the high polymer particles by the liquid.  Suitably, the liquid and surfactant are added in increments and additional surfactant, acid, or alkali are added to reinforce the original charge on the high polymer particles. In particular, a high styrene-butadiene copolymer is mixed with a naphthenic extender oil; butadiene-styrene (75:25 and 25:75) latices are mixed with polymerization initiator, styrene monomer and volatile polyhaloalkane liquid and polymerized to give a dispersion that on drying forms an opaque film; and a styrene/ 2 - ethylhexyl acrylate/divinyl benzene/methacrylic acid copolymer is plasticized with phthalate plasticizers and mixed with ammonia, polyelectrolyte, phenol mercuricpropionate, magnesium montmorillonite, titanium dioxide, calcium carbonate and methyl cellulose, as a paint.  The latter-mentioned copolymer is made by polymerizing the monomers in the presence of potassium persulphate, nonyl phenol polyoxyethylene ethanol, and sodium dodecyl benzene sulphonate.  In a modification, if the extender itself is charged oppositely to the latex no surfactant is required.

Abstract: 191,055. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Automatic Electric Co.). Dec. 24, 1921, [Convention date]. Addition to 169,698. Automatic exchange systems.-In a group of nan-numerical switches E having access to a large group of trunks F, means are provided whereby the idle switches which are standing on busy lines are moved forward in sub-groups when all the remaining switches are in use, instead of being moved together as in the parent Specification. The movement continues until all the idle switches are set on idle lines. Each switch E controls a relay 33, which is energized over the test wiper 35 when the switch stands on a busy trunk, and if all the relays 33 of the group of switches are energized, a circuit is completed for a master relay 32, which closes the circuit of the rotary magnet 45 of a stepping switch W, rotating wipers 46, 48 to their first contacts, whereupon a circuit over the test wiper 35 is completed for the stepping magnet 31 of each idle switch of the first sub-group in series with a slow relay 47 which open-circuits the rotary magnet 45. The idle switches are rotated until they all engage idle trunks, the busy switches being unaffected since the energization of a switching relay 30 opens the circuit of the stepping magnet. On relapse of the slow relay 47, the wipers 46, 48 are rotated to their second contacts, which are associated with the second sub-group of switches, and the action proceeds until all the idle switches in the group engage idle trunks. If all the switches E or all the trunks are busy, the switching relays 58 at the succeeding group selectors are energized, removing at iheir armatures 53, 55 &c. a shortcircuit from a relay 59 which operates to interrupt the circuit of the rotary magnet 45 of the stepping switch W.
