Patent GB-909463-A (GB)
Title: Machine and method for treating particulate solids
Inventor: OPILA ROBERT L
IPC: C08B30/16
Filed: 1959-03-09
Abstract: <PICT:0909463/IV(a)/1> <PICT:0909463/IV(a)/2> A process for mechanically treating finely-divided granular material with or without thermal or chemical treatment comprises moving the material in a thin layer along a flat impervious conveyer surface in the form of a thin shallow stream, raising the material at spaced points along said stream, retarding the rate of forward travel at the forward sides of said points and accelerating the forward motion of said material at the rearside of said points.  Preferably the layer of material is raised at the spaced points, broken into fragments, the fragments crumbled and then dropped back upon the conveyer.  The material may be heated to 95 DEG -230 DEG C. and movement effected on a layer 2-18 mm. thick by means of vibrations having a frequency of 425-710 revolutions per minute and an amplitude of 1/8 to 1/2 inch. In a preferred embodiment carbohydrates to be heat treated are transferred from a hopper 30 to a conveyer 1 by means of a continuous gravimetric feeder 29.  Conveyer 1 is supported by reactor legs 11 and oscillating motion is imparted at the pivot bearing 10 through a connecting rod 4 mounted on an eccentric 6. The carbohydrate is conveyed to the discharge end and into a jacketted container 38 through which cooling water is circulated at a velocity between 2 and 20 feet per minute, the velocity depending on the speed and stroke of the eccentric 6, the angularity of the legs 11 and the design of the mixing element 16 (not shown).  Heat is supplied by means of a liquid heated in a boiler 31 equipped with an expansion tank 32 the liquid being circulated through a jacket 17, returning through a pipe line 36. Heating may also be effected by means of an infra-red generator. The flow of the carbohydrate M is shown diagramatically in Fig. 12. It is caused to move up the slope of angle A which is about 15 degrees to a height of 3/16 inch and then passes over a break angle B of 130 degrees which causes the formation of transverse fissures 42 causing the formation of unstable slabs 43 which crumble on the supporting surface 2a thus causing a complete mixing and providing rapid and uniform heating.  In examples, the process is applied to the production of white and canary dextrin and syrups by the action of hydrochloric acid on starch obtained from maize and potato; and also to the production of esters from modified starches which may have been treated with formaldehyde by reaction with sodium tripolyphosphate, sodium trimetaphosphate, tetrasodium pyrophosphate, or disodium dihydrogen pyrophosphate.  Specification 855,731 is referred to.

Title: Improvements in or relating to the dyeing of artificial silk in the form of wound packages
IPC: D06P1/651
Filed: 1937-03-23
Abstract: In dyeing regenerated cellulose artificial silk in the form of a wound package by treatment with an alkaline dye liquor, swelling of the artificial silk tending to reduce the permeability of the package is restricted by adding to the liquor an organic water-soluble liquid in an amount of less than 25 per cent of the volume of the liquor. Specified alkaline dye liquors are those containing naphthol coupling components, sulphur dyes and leuco vat dyes and specified organic liquids are methyl, ethyl and propyl alcohols and glycols.  In examples, (1) a spun cake of regenerated cellulose artificial silk is washed free from acid and, while still wet, is dyed black by forcing through it an aqueous solution containing sulphur black and sodium sulphide with an addition of 10 per cent of methanol; (2) cops of regenerated cellulose artificial silk are pre-treated by circulating through them an aqueous solution containing the anilide of 2 : 3-hydroxynaphthoic acid, caustic soda and formalin with an addition of isopropanol and the colour is then developed by treatment with an aqueous liquor containing Fast scarlet GGS base, hydrochloric acid and sodium nitrite.
