Filed: 1974-02-20
Abstract: 1462485 Phenoplast resin foams derived from expandable resoles SAINT-GOBAIN INDUSTRIES 20 Feb 1974 [5 March 1974] 7777/74 Headings C3C and C3R [Also in Division B2E] Chemically neutral phenoplast resin foams are made by coating or mixing uniformly a blowing agent on to or with a solid resole-type chemically neutral phenoplast resin in particulate form, which has been made by condensing 1-3À1 moles of formaldehyde with 1 mole of phenol, and then causing the expandable particles to expand and set by the action of heat alone. In the examples spheroidal particles of resin were made by condensing phenol and formaldehyde in water in the presence of hydrazine hydrate, treating the mixture with ammonia and then suspension stabilizers and finally washing and drying the beads. The bead resin was then either mixed or coated with a blowing agent, e.g. namyl alcohol, azo-1,1<SP>1</SP>-cyano-1-cyclo-hexane or benzene sulphohydrazide, and optionally a silicone oil, e.g. a copolymer having dialkylsilicone and alkylene oxide units, optionally shaped, e.g. calendered to form a band or extruded to form a strand which may then be calendered and then heated, e.g. in a mould, stove or on a conveyer belt of a tunnel oven, to form a foam. The foams produced may be chemically neutral and may be used as thermal insulation.

Title: Improvements in or relating to method and apparatus for manufacture of rayon
IPC: D01D10/04
Filed: 1939-03-10
Abstract: 522,347. Finishing yarns. SKENANDOA RAYON CORPORATION. March 10, 1939, No. 7795. Convention date, March 11, 1938. [Class 130 (iii)] [Also in Group IV] Artificial silk cakes are subjected to the action of primarily compressive forces applied simultaneously over the entire outer peripheral surface of each cake, and acting substantially tangentially. The treatment results in cakes of reduced diameter and of looser structure thus facilitating more uniform access of treating liquids and more uniform shrinking during drying. The artificial silk may be spun in pots having internal ribs 11 as shown in Fig. 15. The cakes may be protected by being wrapped in an elastic fabric or stocking. For the reducing treatment each cake may be placed within and subjected to the compressive action of a stretched band of rubber or the like. As shown in Figs. 9, 10, a rubber band 15 is pivotally connected to blocks 14 capable of radial movement. Inward movement is restricted by stops 14a. The blocks 14 may be fixed by hooks 20 to hinged arms 26. Outward movement of arms 26 causes outward movement of the blocks and stretching of band 15. When a cake has been inserted within band 15, the latter is allowed to contract upon the cake. The contractive forces may be strengthened by providing an additional elastic band 27. As shown in Fig. 11, the rods 28 carrying the elastic band 15 are mounted at their lower ends on radially-movable sliding plates 29 which move in slots 30 in a fixed plate 31. The plates 29 carry pins with rollers 33 which move in slots 34 of a rotarily reciprocating cam-plate 35. The pins are retracted outwardly on rotation of the cam-plate, and the elastic band 15 is stretched to receive an artificial silk cake. Specification 290,833, [Class 2 (ii)], is referred to.

Title: Improvements in the Manufacture of Potassium Chloride from Natural Silicates, Rocks, Minerals, Residues or Wastes containing Potash.
Inventor: ASHCROFT EDGAR ARTHUR
IPC: C01D3/08
Filed: 1917-06-05
Abstract: 113,211. Ashcroft, E. A. June 5, 1917. Potassium salts, obtaining from complex sili. cates. Potassium chloride is obtained from silicates such as feldspar, leucite, &c., by treatment of the crushed material with fused sodium chloride or alkaline earth chloride. The invention is described with reference to the use of sodium chloride. The reaction may be effected in batches in closed crucibles or retorts, or the fused salt may be caused to percolate through the crushed silicate, most of the potash being found in the salt which collects at the bottom. In any case, air and moisture must be excluded. When percolation is employed, some of the salt may be mixed with the silicate, for instance by mixing with the silicate the salt solution obtained by leaching the solid residue, and drying at a temperature too low to cause any reaction. Suction may be employed to assist the percolation and some magnesium chloride may be added to make the salt more fluid.
