Patent GB-650152-A (GB)
Title: A process of improving the slippage characteristics of films and foils
IPC: C08J7/02
Filed: 1948-09-14
Abstract: The slippage characteristics of a film of a plasticized cellulose derivative are improved by moistening, e.g. coating or swabbing, one surface of the film with carbon tetrachloride or toluene, or a mixture of these liquids, drying the treated film, and buffing the dried surface.  Preferably a mixture of carbon tetrachloride and toluene in the ratio of 70 to 30 by volume is used.  The treated films will readily slip over one another or over polished metal surfaces without accumulating static electrical charges.  The treatment may be applied to a cellulose derivative support film itself or to the cellulose derivative support side of a finished photographic film, e.g. motion picture film.  The cellulose derivative may be a cellulose ester such as a nitrate, acetate, formate, propionate, butyrate, or acetate-propionate or other mixed cellulose ester.  In an example, a cellulose acetate film support is wiped with cotton which has been moistened with carbon tetrachloride and is allowed to dry at room temperature.  The dried strip is then buffed with felt until it becomes glossy.  In another example, a mixture of carbon tetrachloride and toluene is sprayed on to one surface of a cellulose acetate-butyrate film base.  After drying, the surface is buffed with felt.

[Also in Group II] Raw coal is separ ated, by means of a magnetite suspension in a separator 1, intc washed coal and shale. The coal fraction with some sepa rating suspension leaves at B and passes across a screen 2, the suspension dripping through and being collected in a tank 3 for return to the separator by a pump 4. The fraction is then passed across a screen 5 where it is cleaned by water sprays 6, 7 before being discharged at D. The shale, which leaves the separator 1 at C, undergoes similar treatment and is discharged at E ; the screens 2, 5 may be of the vibrating type with a mesh of 1mm. The dilute suspension passing through the screens 5 is collected in a tank 8 and supplied by means of a pump 9 to a curved screen 10 consisting of spaced bars having gaps of 0À5 mm. between them. 90% of the magnetite contained in the dilute suspension is collected in a tank 11 beneath the screen 10 and is then passed to a magnetic separator 12 from which a concentrated magnetic suspension is pumped to the collecting tank 3 via a demagnetising coil 14. This suspension together with that from the screens 2 is then pumped to the separator 1. Alternatively, the suspension from magnetic separator 12 may be pumped direct to the separator 1. Water may be added to the separator 1 at G. In the separator 12 also, a dilute non-magnetic fraction which contains only non-magnetisable particles smaller than 0À25 mm. is separated out and supplied to a tank 15 which also receives the overflow fraction from the screen 10 consisting mainly of the non- magnetisable particles larger than the magnetite. The fractions collected in the tank 15 are pumped into a hydrocyclone thickener 17 from which the clarified overflow is led to the sprays 6 and the apex discharge is treated in a second magnetic separator 18. The separated magnetic fraction is returned to the tank 8 and the non-magnetic fraction leaves the system at F. In place of the screen 10, a cyclone separator or a group thereof may be used.
