Title: Improvements to coatings of vinylidene chloride copolymers
Inventor: BARROW ROWLAND
IPC: C09D127/08
Filed: 1960-02-04
Abstract: Coatings for transparent moisture-proof wrapping materials comprise not less than 95 wt. per cent of a copolymer, containing at least 85 wt. per cent of vinylidene chloride, and 0,5 to 5 wt. per cent of an acid anhydride derived from C12-18 saturated fatty acids.  Specified vinylidene chloride copolymers are those wherein the predominant comonomer is acrylonitrile. They may contain also mono-n-butyl itaconate as described in Specification 913,043 or have grafted side-chains of polyethylene imine as described in Specification 812,130.  They are preferably soluble in organic solvents but may also be used in aqueous dispersion.  Anhydrides specified are palmitic, lauric, myristic and stearic.  In examples the copolymer compositions were dissolved in 50/50 methyl ethyl ketone/toluene to yield a clear lacquer which was used to coat a regenerated cellulose film which had been softened with glycerine and treated with a melamine-formaldehyde resin as anchoring agent.  Specifications 655,006, 766,708 and 913,044 also are referred to.

Patent GB-836954-A (GB)
Title: A process for preparing organosilicon polymers
IPC: C08G77/388
Filed: 1958-02-11
Abstract: Organosilicon polymers comprising siloxane units are made by reacting (1) an organosilicon compound containing at least one SiOH group per molecule and containing an average of at least one Si-bonded organic radical per Si atom, the organic radicals being free from active hydrogen, any remaining valencies of the Si being satisfied by hydrogen, oxygen, divalent hydrocarbon radicals, other Si atoms or hydrolysable radicals free from active hydrogen, with (2) an organic mono-isocyanate.  Copolymers are obtained when two or more silicon compounds (1) are used in the above reaction.  Polymerization is stated to be by way of condensation of two Si-OH groups under the influence of the isocyanate which splits up into CO2 and a disubstituted urea, which may subsequently be removed by volatilization.  The isocyanate may contain other functional groups free from active hydrogen, e.g. nitrile, halogen, nitro, ester, ether, sulphide or t-amine groups.  Organosilicon compounds specified are silanols, partial condensates thereof, silcarbanes, polysilanes and siloxanes containing residual hydrolysable radicals, e.g. halogen, alkoxy and aryloxy radicals; the Si-bonded organic radicals may be saturated or unsaturated aliphatic or aromatic radicals and may contain halo-, cyano-, nitro-, amino- or carboxy-substituents. The reaction may be effected at any temperature, e.g. from below room temperature to 250 DEG  C. or above, and in the absence or presence of solvents to yield products free from volatile cyclics. The isocyanate is preferably used in amount from 0.5 to 1.5 mols. per mol. of SiOH in the organosilicon compound.  In typical examples phenyl isocyanate was reacted with (1) a hydroxylated liquid dimethylsiloxane to give a product of increased viscosity and finally a gum; and (4) a mixture of triphenylsilanol and a hydroxylated dimethylsiloxane to yield a co-polymer; (16) octadecylisocyanate was reacted with diphenylsilanediol at 50 DEG  C. to give diphenylsiloxane polymers.

Magnetic instruments; loud-speakers. -The casing of a loudspeaking telephone receiver is made wholly or partly of a vitreous or ceramic material, such as glass, silica or porcelain. Fig. 1 shows a loud speaking telephone receiver casing in which the portion 1 for housing the electromagnetic unit and the cover 3 are formed of a vitreous or ceramic material, the two parts being secured together by a screwthreaded flanged ring 2. Feet 10 may be formed on the portion 1. In modified constructions, the end 1<b> of the portion 1 is formed separate and may either be secured thereto by a screw threaded flanged ring similar to the ring 2 or adapted to screw into or on to the portion 1. In the construction shown in Fig. 5, the cover 3 is formed with a rim 3<a> adapted to screw on to the portion 1 and of such axial length as to form a support for the whole casing. In cases in which two glass &c. portions are screwed together, a ring 12 of felt &c., preferably formed to a screwthreaded shape, may be interposed between the two portions. In a further modification, Fig. 6, in which the portion 1 is formed of glass &c. and the cover 3 and end portion 1<b> are formed of different material, the whole is secured together by bolts 13 and nuts 15, the, bolts passing through a number of correspondingly arranged holes in the three portions.

Abstract: 676,957. Casting-machines; moulds; cores. PLASCO, Ltd. (Morin, L. H.). Feb. 28, 1951, No. 4839/51. Class 83 (i). A die-casting machine has a pair of dies movable towards and away from one another, at least one pivoted core carrying a core pin to form an undercut hole in the casting, said core being disposed between cavities on adjacent faces of the dies and means, comprising a slide, for moving said core relative to the open dies and to free it from the casting. Fig. 1 shows a machine, for casting sliders for sliding-clasp fasteners, with the die 20 and cores in closed position, the die 21 being omitted to disclose the cores. These comprise two cores 24, 25 pivoted at 70 to a slide 59 operated by a lever 64, one core 22 secured by rivets 74 to the slide and one core 23 fixed or moved in directions opposite to the core 22. The die 21 has all the gate-passages 50, 48, 49, Fig. 6, an expenasion chamber 51, a recess 47 to mould the back 10, Fig. 5, of the slider, a groove 54 for the core 22 and a notch 52 to receive an aligning rib 53 of the die 20. This has a recess 31 to mould the front 11, Fig. 5, and a projection 32 to form a locking hole 18 therein, grooves 26, 27 to receive the ends of the cores 24, 25, and a projection 56 to close the open side of the nozzle 55 of the die 21. The pivoted cores 24, 25 have grooves 33, 34 for the core 22, faces 38 to mould the outer faces of the flanges 14, Fig. 5, and recesses 36 and pins 37 to mould the outer faces and perforations 16 of the lugs 15. The cores 22, 23 mould the inside faces of the slider, 23 sliding into the forked end of 22. After casting, the dies 20, 21 are moved out, the core 23 may be moved down or remain fixed and the slide 59 is moved up. When rollers 76 on the upper ends of the cores 24, 25 pass beyond the upper end of a fixed spreader-bar 79 they engage cam faces 62 which force them inwardly, thus separating their lower ends to free them from the casting which is stripped by a fixed pin. The parts are then moved in the reverse direction, the bar 79 bringing the lower ends of the cores 24, 25 together to enter the grooves 26, 27 of the die 20. The operation can then be repeated.

[Also in Division G2] Apparatus for manufacturing patterns or templates for eyeglass lenses comprises copying means, rotatable spectacle frame mounting means in resilient contact with the copying means, template mounting means which works together with the mounting means and vertically reciprocable means for cutting the template to the outline of the spectacle frame. A spectacle frame A is placed on a stand 6 mounted on a shaft 2 and secured in position by clamps 8, 8<SP>1</SP>. A lever 19 is rotated as shown in Fig. 3 to close a micro-switch thereby starting a slow-speed motor m and the main motor M. Rotation of the lever 19 is transmitted to a copying arm 22 by a spring 20 and shaft 21 thereby moving forward the tip 23 of a copying piece into contact with the inside of the frame A and pivoting the stand 6 and shaft 2 against the action of a spring 4 to hold the tip 23 against the frame through the work cycle.
