Title: Production of dyed and crimped staple fibre
IPC: D06P7/00
Filed: 1948-06-11
Abstract: Continuous filaments of an organic derivative of cellulose in tow form are dyed, crimped and the tow cut into staple fibre.  The material comprising the filaments may be cellulose acetate, propionate, butyrate, acetate-propionate or acetate-butyrate or ethers such as ethyl or benzyl cellulose.  The dyeing is preferably effected with an aqueous solution of the dye containing a lower aliphatic alcohol and a thiocyanate in known manner, using 75-95 per cent alcohol by volume and 25-35 grams per litre of the thiocyanate (e.g. sodium thiocyanate), at a dyeing temperature of 25-35 DEG  C. The preferred procedure is as follows: the tow leaving the spinning machine is dried and cooled, then dyed and washed and given a lubricating and antistatic finish.  It is then dried to a moisture content of 20-30 per cent, crimped and cut. The crimping may be effected by a stuffing box method in known manner.  In an example a dye bath is made up using Artol Blue GL, Cloth Fast Orange G and Neolan Orange R in a mixture of 250 parts by volume of water and 750 parts by volume of 95 per cent ethyl alcohol.  25-30 g./litre sodium thiocyanate are then dissolved in the liquor.  A lubricated tow of cellulose acetate continuous filaments is dried at 80-90 DEG  C., cooled to 25 DEG  C. and dyed in the above bath at 30 DEG  C.  After leaving the bath and passing through nip rollers it is washed, treated with a lubricating and antistatic finish, dried to a moisture content of 25 per cent and crimped by the stuffing box method.  It is finally dried to a moisture content of 6 per cent and cut into staple fibres.

Title: Process for the manufacture of compositions and articles of high thermic resistivityand low specific gravity
IPC: C04B20/02
Filed: 1930-05-23
Abstract: Compositions having low specific gravity and low thermal conductivity are formed by treating magnesium or aluminium silicates such as asbestos and mica either alone or in combination as an artificial or natural mixture, with dilute hydrofluoric acid so that the asbestos &c. becomes coated with metallic fluoride which serves as a binding agent.  Hydrofluosilicic acid may also be used.  Excess of acid is used to ensure rapid action on the silicates, neutralization of caustic alkali and conversion of starch into gum.  Remaining traces of acid may be neutralized by magnesium carbonate.  The wet material may be cast and heated to remove excess of moisture, or mixed with an adhesive comprising caustic alkali and starch, gums or vegetable jelly so that it may be used as lagging around steam pipes which evaporate the moisture, or may be mixed with powdered or granulated cork to form fireproof material, flooring tiles or insulating material for cold storage chambers.  In making bricks &c. for furnace linings &c. moderate heating to remove moisture may be followed by heating to 1200 DEG  C.

Filed: 1947-06-20
Abstract: 635,369. Knurling. WILLETT, V. W. June 20, 1947, No. 16353. [Class 83 (iv)] A knurling-tool comprises a tubular mounting shank terminating in a head which has a workreceiving bore and in which at least three knurling-wheels are mounted upon movable supports so that they may be moved simultaneously towards and away from the centre of the bore by means characterized by a correlating ring and a ring operating linkage which is adapted to pass through a deadcentre position to determine the closed position of the wheels. The head 2 comprises members 2a, 2b between which is supported a ring 7, rotatable by means of a handle 11 integral with a link 9 pivoted at one end to the head section 2b and connected at the other end to a screwed rod 10 adjustably connected to a forked lug 8 on the ring 7, so that the angular stroke of the ring may be varied. Links 24 are each pivoted at one end to equidistantly spaced pivots 26 on the ring and carry at their other ends pins 27 which ride in circumferential slots 28 in plungers 22 mounted in guide ways 22a. Thus angular displacement of the ring 7 is converted to radial movement of knurling-wheels 18 carried at the ends of the plungers 22. Each plunger 22 has two key-ways 29, 30, along its sides, one of which is engaged by a set-screw 32 to guide the plunger longitudinally, so that the knurling-wheel may be set at an angle to the work. A spring 12 loads the ring 7 to assist in maintaining the plungers in the open (chain dotted) or closed position, the limits of movement of the link 9 being defined by its engagement with the edge of the slot in the member 2b through which it projects and the edge 33 of the ring 7 respectively. When an article has been knurled down to a diameter set by the adjustable rod 10, a striker may automatically knock the handle 11 to the open position. In a modification, Figs. 5 and 6, knurling-wheels 63 are carried at the ends of supports 58 which are pivoted at 60 to a rotatable head ring 42 and located between pairs of abutment pins 65, 66 projecting from the end face of the head. Each support is held against the pin 65 by a leaf-spring 69, and angular movement of the ring 42 to the open position (chain dotted) by means of the handle 59 through a linkage 53, 54 causes the supports 58 to rotate about the pivots 60 causing the knurling-wheels to withdraw. An adjustable collar 41 carrying the linkage 53, 54 has a cut-away portion 52, whose engagement with the knee of the linkage limits the inward movement of the wheels. By adjusting the angular position of the collar 41 the range of movement of the knurling-wheel supports may be varied. A direct reading scale on a shank-retaining ring indicates work diameter.
