Title: Improvements in or relating to the manufacture of coating compositions
IPC: C09D107/00
Filed: 1932-04-29
Abstract: Coating-compositions comprising rubber and powders of good covering power are prepared by mixing the powders with irreversible granular precipitates of rubber and the like in any suitable paint mill.  The granular precipitates are prepared in known manner by precipitation in situ of compounding ingredients, or by the addition of coagulating agents to the dilute dispersion with or without the addition of alkaline or colloidal substances having a restraining effect on coagulation.  Vulcanizing and compounding ingredients may be added as dispersions either before or after the formation of the granular precipitates, or before or after the admixture with powders of good covering power.  In an example, for the production of a white water distemper, 150 parts of 6 per cent latex are added to 30 parts of sodium silicate dissolved in an equal amount of water.  This is diluted to form a 5 per cent solution and 24 parts of a 5 per cent solution of aluminium sulphate are added with stirring.  The granular precipitate obtained is allowed tostand over a filter cloth to attain a creamy mass of 16 per cent concentration.  A mix comprising 600 parts zinc oxide, 500 parts china clay, 3,75 parts gum acacia, 3,75 parts gelatin, 7,5 parts ,880 ammonia, 985 parts water, 900 parts of the rubber precipitate obtained above are mixed in a paint mill to uniform consistency. Specifications 219,635 and 290,313, [both in Class 70, Indiarubber &c.], are referred to.ALSO:Coating-compositions comprising rubber and powders of good covering power are prepared by mixing the powders with irreversible granular precipitate of rubber and the like in any suitable paint mill.

Title: Reel winding apparatus
IPC: B65H67/056
Filed: 1962-03-30
Abstract: 957,574. Reels, raising and lowering. CROMPTON & KNOWLES CORPORATION. March 30, 1962 [April 25, 1961],No. 12407/62. Heading B8M. [Also in Division D1]  A reel winding apparatus includes at least one platform 172, Fig. 1, that can be displaced between an upper position (see left-hand platform) at which it supports a reel R. In alignment with bearing, B for the reel, and a lower position (see right-hand platform) at which a reel can be rolled from said platform on to the floor or vice versa, the platform having ribs 238 preventing the reel R from rolling from its desired setting on the platform 172. In the apparatus shown there are two platforms 172 enabling two reels R to be selectively moved in to and out of alignment with a winding position as defined by the bearings B to permit continuous reeling to take place. Each platform is actuated by a piston and cylinder unit 208 coupled to the platform via a chain 214 passing over sprockets 218. The chain 214 is coupled to the piston via a member 224 that can be adjusted to abut the cylinder when the piston therein has descended to a desired extent, this arrangement permitting the upper setting of the platform to be predetermined to ensure that the axis of the reel, when raised by its supporting platform, shall be in true alignment with the bearings B. Each platform 172 carries a slide 204, Figs. 1 and 3, operable by a piston and cylinder unit 250 such that, for example, when the righthand platform 172 has been raised to align the empty reel R with the bearings B, the slide 204 is displaced to the left to engage the empty reel R with the left-hand bearing B on a fixed central hanger 42. Thereafter a further piston and cylinder unit 66 slides a movable hanger 58 to the left to cause the right-hand bearing B to engage the empty reel R. The slide 204 carries a shoulder 262 to ensure that when the reel is filled and the hanger 58 is eventually moved away from the reel, the shoulder 262 will prevent the reel from following the bearing B on the hanger 58. The slide 204 carries a further shoulder 264 to ensure that when the slide 204 is eventually moved to the right the shoulder 264 will abut the now filled reel and force it to move off the bearing on the central hanger 42. The platform 172 is then lowered and the now filled reel is rolled off the platform and on to the floor via range 272 or ramp 276 Fig. 3.
