Title: Improvements in the manufacture and treatment of viscose
IPC: D01F2/08
Filed: 1921-04-11
Abstract: Viscose is prepared from cellulose rendered colloidal by high speed mechanical disintegration, as by grinding in the so-called colloid mill described in Specification 179,124, in the presence of a liquid dispersion medium, preferably a solution of caustic soda; to the alkali-cellulose so obtained, carbon bisulphide is added, and the reaction continued in the same apparatus with vigorous beating.  By this process, smaller quantities of alkali and carbon bisulphide are necessary, and quantities of the former may be employed corresponding to the monosodium and disodium viscoses; further, ripening of the viscose is either unnecessary, or may, in the case of artificial silk, be reduced to a few hours. Plastic masses may be obtained by heating to 80-100 DEG  C. the viscose solution prepared as above described, or with which has been incorporated, during the dispersion stage, substances such as resin or rubber, which modify the properties of the product. By the addition of sodium chloride or other inert electrolyte, a product in the form of a fine powder after washing and drying, is obtained suitable for moulding into various articles by moulds heated to 120-150 DEG  C. and under a pressure of 200-500 atmospheres.  An adhesive may be prepared by adding starch during the dispersion stage.  The solution may also be evaporated to give a dry water-soluble product, stable in vacuo or in an inert gas such as nitrogen or hydrogen; in air, the dried product changes slowly and becomes irreversible.ALSO:An adhesive is prepared from a viscose obtained from a cellulose which has been subjected to high-speed mechanical disintegration, by adding starch during the dispersion stage.ALSO:Solutions of viscose are prepared from cellulose rendered colloidal by high speed mechanical disintegration, as by grinding in the so-called colloid mill described in Specification 179,124, in the presence of a liquid dispersion medium, preferably a solution of caustic soda; to the alkali-cellulose so obtained, carbon bisulphide is added, and the reaction continued in the same apparatus with vigorous beating.

Title: Improvements in or relating to fluid-operated apparatus for detecting material objects
IPC: F15B5/00
Filed: 1964-03-13
Abstract: 1,055,322. Regulating fluid flow. R.E. BOWLES. March 13, 1964 [April 12, 1963], No. 10733/64. Heading G3H. [Also in Division G4] A pure fluid device for detecting the presence of an object and suitable for counting movable objects comprises, in one embodiment, Fig. 1, a nozzle 1 the discharge from which tends to flow to an outlet 9, and a nozzle 13 discharging into a tube 14 to set up a back pressure in the outlet 9 so that the major part of the discharge from the nozzle 1 flows to an outlet 12. An object 16 interrupting the flow from the nozzle 13 allows the discharge from the nozzle 1 to pass to the outlet 9. The constricted passage 17 from the outlet 12 may lead to a pure fluid counting device, flip-flop, &c., or a mechanical or electrical load. To enable larger objects to be detected, the discharge from the nozzle 13 may be deflected by a further nozzle at right-angles to the nozzle 13 and the objects arranged to interrupt the flow from this further nozzle. Instead of discharging towards the outlet 9, the nozzle 13 may be directed towards a control nozzle in the region 2 between the nozzle 1 and the outlets 9, 12. Fig. 8 shows a flow diverter 37 which, when suitably situated in relation to discharge and receiver nozzles 43, 44, directs flow from the nozzle 43 to the nozzle 44. Two or four such flow diverters may be adjustably mounted on a tote box in a conveyer system so that the box is, or is not, diverted according to whether or not the positions of the flow diverters correspond with the positions of fixed reading heads, each comprising a pair of nozzles 43, 44. The apparatus for diverting the tote box may be controlled from the nozzles through a combination of pure fluid amplifier devices. Alternatively the approach of a tote box may be detected by a single flow diverter 37. A flow diverter 37 may have a through passage for operating elements, e.g. a pure fluid counter device, spool valve and compressed air valve, carried by a tote box each time the latter passes a nozzle 43. When the counter reaches a particular count it causes operation of the spool valve which results in opening of the compressed air valve to deflect the box or apply a brake. Apparatus responsive to the proximity of an object 102, Fig. 12, comprises a nozzle 101 with a tendency to discharge to an outlet 96, and a nozzle 93 which normally discharges into the outlet 96 to cause the major part of the discharge from the nozzle 101 to pass to an outlet 99. As the object 102 approaches it causes the discharge from the nozzle 93 to switch upwardly whereupon the flow from the nozzle 101 is transferred to the outlet 96. This apparatus may be used to gauge whether or not the thickness of objects passed over it lies within a predetermined range.
