Patent FI-974085-A (FI)
Inventor: NURMI ANTTI
IPC: B07B1/15
Filed: 1997-10-29
Abstract: The invention relates to an arrangement for the screening and crushing of bulk material, the arrangement separating a desired grain size and oversize material from one another, and reducing the oversize material to the desired size, the arrangement comprising a plurality of disk shafts 2 rotating about axes of rotation having the same alignment, on which disks toothed disks 4 have been arranged or formed at an interval from one another, which are arranged so that disks of adjacent axes overlap one another, so that the upper surface of the disk shaft arrangement forms a track for the material that is to be processed. In order to optimize the simultaneous screening and crushing process and to improve on the existing process, the disks 4 of adjacent shafts and the shaft surfaces 2 between the disks form compartments for material particles of desired size, so that in operation of the arrangement the disk shaft arrangement simultaneously screens material of the desired size and crushes oversize material. <IMAGE>

Patent GB-450514-A (GB)
Title: Improvements in or relating to the recovery of copper in the manufacture of cuprammonium artificial silk
IPC: C01G3/14
Filed: 1935-01-15
Abstract: Copper contained in cuprammonium artificial silk lyes is recovered by conversion into cuprous chloride followed by oxidation of the latter to copper oxychloride which is used, after dechlorination if desired, to produce a new Schweitzer's solution. The lyes comprise a sulphuric acid solution rich in copper (spinning acid) and an ammoniacal lye poor in copper (blue water).  The copper in the copper rich lye may be first cemented, and the cement copper added to lyes obtained in the chlorination of roasted copper ores, or to technical copper sulphate lyes obtained, for instance, from the electrolysis of copper, to which sodium chloride has been added.  Part of the ammoniacal lye may be treated with lime, and the copper hydroxide formed added to the copper rich lye before cementation.  The resultant cuprous chloride-cement copper mixture is separated, the cuprous chloride dissolved in sodium chloride solution, and oxidized by air, for example, at 75 DEG  C.  If technical lyes containing sodium chloride are not available, the lye rich in copper may be divided into two parts, one part and the ammoniacal lye being cemented, and the cement copper mixed with the other part to which sodium chloride has been added.  In another method, copper rich lye is neutralized with copper oxychloride obtained by the process of the invention or with basic carbonate obtained therefrom, and the neutral solution treated with soda to precipitate a basic copper salt which is used to produce the Schweitzer's solution.  Iron may be removed during the formation of the solution of cuprous chloride by blowing in air.  If all of the copper in the lyes is cemented, the necessary chloride ions may be obtained by treating this cement copper with chlorine, or by dissolving part of the oxychloride in hydrochloric acid, and adding this solution to the cement copper.

Title: Method for the production of improved cellulosic fabrics
Filed: 1935-01-16
Abstract: Cellulosic textiles and textile materials whether natural or artificial, and cellulosic films &c. are modified by treating them at 110 DEG  C. or above with formaldehyde and an acid or an acid-producing substance including ammonium sulphocyanide.  The formaldehyde and acid &c. may be applied by simple impregnation or by working the materials in a liquor which may be cold or heated to a moderate temperature, or by printing; after impregnation, the materials may be centrifuged or squeezed, and they may be before the heating dried at a lower temperature; after the heating, traces of formaldehyde may be removed by a simple washing with ammonia, soap, &c.  Materials so treated are distinguished by a reduced affinity for dyes or if dyed with substantive direct dyes by an improved fastness to washing, by a decreased tendency to creasing or crumpling, and by an increased resistance to water and a lower shrinkage effect when wetted or mercerized.  In examples, the treating liquors or printing pastes contain in addition to formaldehyde, ammonium sulphocyanide, phosphoric acid, sodium bisulphate and potassium tetraoxalate, and the heating is conducted at 120--150 DEG  C. in a heated chamber or by passage over heated rollers or through a hot flue or chamber. Specifications 25647/06, [Class 2], 200,881, 234,618, [both in Class 2 (ii)], and 414,576 are referred to.
