Abstract: 526,399. Refining cellulosic materials. PALAZZO, F. C. March 15, 1939, No. 8287. Convention date, March 16, 1938. [Class 2 (ii)] Cellulose, particularly for the manufacture of rayon, is obtained from pine woods having a large resin content by subjecting the wood for a period of from 1 to 2 hours and at a temperature of from 90-95‹C. to the action of an alkaline lye, containing from 0.1 to 0.2 per cent. of sodium hydroxide, after which the product is digested in a bisulphite lye. The bisulphite digestion may be carried out at 106-108‹C. with a lye containing 0.5 to 1 per cent. of calcium oxide, and from 5 to 6 per cent. of free and combined sulphur dioxide. Bleaching of the treated cellulose may be carried out in two stages, with a hypochlorite solution which, without being acidified with strong mineral acid, contains about half of the hypochlorous acid in the free state and half as a calcium or sodium salt. A treatment with sodium hydroxide solution may be interposed between the two bleaching treatments. Last traces of hypochlorous acid may be removed by subjecting the cellulose material to treatment with sulphurous acid solution. Wood which may be treated by the process includes that of the red fir or Scotch pine, and the cluster pine or pinaster.

Abstract: In an electrodialysis cell which comprises a series of narrow compartments bounded on their major faces by ion-permeable or ion-selective membranes 16 and disposed within the open centres of spacers interposed between adjacent membranes, the membranes and spacers together forming a stack between end electrodes, and conduits 19 being formed through the cell by co-operating holes in the membranes and spacers, each spacer is formed of a pair of sheets 1, 11 mating face to face so that slots in the two sheets form passages leading from liquid supply and removal conduit-forming holes to each compartment, the slot 7 in one sheet merging into a hole 3 but being closed off from the open centre 2 at its inner end while the slot 11 in the other sheet merges into the open centre 21 but is closed off from the hole 31, and the construction is such that each face of the spacer makes continuous contact with the adjacent membrane over an area that lies between the open centre and the conduit-forming holes. Either each sheet is formed with two identical <PICT:1013464/C6-C7/1> <PICT:1013464/C6-C7/2> <PICT:1013464/C6-C7/3> slots arranged on opposite sides of the central opening so that two different sheets are used to form each spacer or each sheet may have slots 7 as in Fig. 1 on one side of the central opening and slots 11 as in Fig. 2 on the opposite side of the opening, one sheet being turned top to bottom relatively to the other to form the spacer.  A thin gauze 18, e.g. of nylon, may be disposed between the portions of the sheets defining the passages to the conduits 19 if the compartments are filled with granular ion-exchange resin, the two sheets and the gauze of each spacer then being united into a single element.  Normally one liquid flows through every alternate compartment of the cell and a different liquid through the other compartments and the pressure on the two liquids may differ without danger of leakage between the flow paths due to bowing of the membranes.  The directions of liquid flow may be at right angles as in Specification 845,186, the holes 5, 6 and 51, 61 forming supply and withdrawal conduits for one of the liquids. Each sheet may be made up of a number of side-by-side pieces and the Specification also states that each spacer may be moulded as a single unit from a plastic such as polythene, polypropylene, or polyvinyl chloride without claiming such an arrangement.

Abstract: 492,325. Adjustably securing cams on shafts. EYRE, D., and ROBINSON, N. R. March 23, 1937, No. 8523. [Class 80 (ii)] In an ignition-timer for an internal-combustion engine, a vernier adjusting means for varying the angular relation of a contactbreaker cam D<1> on its shaft A comprises an intermediate disc B<1>, having on its opposed faces oppositely-directed ratchet teeth differing in number and engaging respectively with complementary teeth on a sleeve B, fixed to the shaft A, and on a sleeve B<2>, which latter drives the cam D<1> through facial teeth E, which are offset from a diameter so that the cam D<1> can be removed and replaced only in the same precise angular relationship without affecting the setting of the vernier-toothed coupling. The vernier discs are rigidly held together and the cam is held on the shaft by a screw D' threaded into an extension A<1> of the shaft A. A spring C, bearing on an expansible ring C<2>, permanently maintains the vernier discs in resilient engagement. After removal of the screw D<2>, vernier adjustment is effected by turning the cam D<1> alternately forwards and backwards so that the intermediate disc B<1> ratchets alternately over the driving and driven discs B, B<2>. The spring C permits this ratcheting, and also holds the vernier together if the cam D<1> is removed. In a modification, the cam is hollow and the vernier coupling is arranged inside it. The offset-tooth coupling is arranged between the lower vernier ring and the shaft, so that the vernier coupling stays with the cam when the latter is removed.
