Patent GB-611830-A (GB)
Title: A process for the emulsion polymerisation of vinyl compounds
IPC: C08F2/22
Filed: 1946-05-09
Abstract: Vinyl monomers are emulsified in aqueous liquid by exposure to mechanical vibrations of a frequency of at least 5 kc./sec., a polymerization catalyst being present.  The monomer may be emulsified and polymerized concurrently or emulsified separately. In Fig. 1, a quartz crystal 2 is made to vibrate by applying a voltage from generator 5, one lead being connected to the metal block 3 mounted on the insulator 4 and the other lead being connected <PICT:0611830/III/1> <PICT:0611830/III/2> <PICT:0611830/III/3> <PICT:0611830/III/4> to the water 6 in cylinder 1, the monomer 7 being at the surface. In Fig. 2, a nickel tube 9 containing monomer and water mixture is placed in the coil 12 which is supplied with 20 kc./s. current with a superimposed direct current.  By magneto striction the tube 9 alters regularly in length.  In Fig. 3, the vibrations are passed along a glass rod 13, one end of which is in the liquid 25 and the other is excited by the movement of two leather belts 16, rotated on pulleys 17 and 18 and held in contact with the rod by springs 23 and 24.  In Fig. 4, the monomer is passed along the whistle 29 from container 26 under pressure exerted by pump 30, through a small hole 31 opposite which is a knife edge 32 of spring steel, and into the water 28.  The knife edge vibrates at its natural frequency by reason of the flow of liquids.  Pipe 35 gives a means of continuous circulation.ALSO:In the emulsion polymerization of vinyl monomers such as styrene, acrylonitrile, methyl methacrylate, vinyl and vinylidene chlorides, the monomer is emulsified by exposure to mechanical vibrations of a frequency of at <PICT:0611830/IV(a)/1> <PICT:0611830/IV(a)/2> least 5 kc./sec. in an aqueous liquid in the presence of a polymerization catalyst, those specified being hydrogen and benzoyl peroxides and sodium persulphate.  The emulsion may be made separately and then polymerized or the polymerization and emulsification may be carried out concurrently or part of the emulsion may be removed from polymerizing conditions and passed into a vessel where it is subjected to the vibrations.  The oscillations may be produced by supplying an alternating current to a quartz crystal placed in the bottom of a vessel filled with water and monomer, or by magneto striction in which a nickel vessel is placed in an alternating field, or, as in Fig. 3, by passing the vibrations along a glass rod 13, one end of which is in the liquid 25 and the other is excited by the movement of two leather belts 16 rotated on the pulleys 17 and 18 and held in contact with the rod by springs 23 and 24, or, as in Fig. 4, by means of a whistle 29 along which monomer is passed from container 36 at a pressure of 10 atmospheres by pump 30, through a small hole 31 into the water 28.  Opposite the small hole is a spring steel knife edge 32, the natural vibrational frequency of which is 10 kc./sec.  The knife edge vibrates at this frequency as the liquid impinges on it.  Continuous circulation of the emulsion is obtained via pipe 35.

Abstract: 1,157,168. Printing surfaces. ELECTROGRAPHIC CORP. 28 March, 1967 [28 March, 1966], No. 14140/67. Heading B6C. A composite electrotype printing plate is produced by shaping under heat and pressure a mass of thermosetting material using a photoengraved plate so as to form a mould 10, removing the plate, spraying a layer 11 of silver on the mould, electro-depositing a thin electrotype shell 12 of copper on the layer 11, and backing up the shell while it is still in contact with the mould with a layer of acrylonitrile-butadiene-styrene thermoplastic resin 18. The backing is bonded to the shell by heat and pressure and the backed shell 11, 12, 18 is then removed from the mould 10. A rigid metal backing member is then adhesively secured to the layer 18 using heat and pressure. The metal member may be flat or curved, Fig. 3 (not shown), in which latter case the layer 18 is warmed and bent to the desired configuration before being inserted with the metal member (28) in the press (24), (32). Pins (26) ensure correct registration. A thin deposit of chromium or nickel may be applied to the silver layer before the layer of copper 12. The shells may be between 0À007 and 0À012 inch in thickness. Before the application of the backing layer 18 adhesive is applied to the rear of the shell and small cavities such as 16 are filled with powdered acrylonitrile-butadiene-styrene resin. The layer 18 may be applied in sheet or powdered form to produce a backing of 0À030 inch thickness. The mould is preferably produced from a sheet of partially cured phenolicformaldehyde or urea-formaldehyde.
