Title: Process for refining agave and manila hemp fibres
IPC: D01C1/02
Filed: 1949-05-13
Abstract: Agave fibres such as sisal or henequen fibres, or Manilla hemp fibres, are refined and their textile properties are improved by treating them at a temperature of at least 60 DEG  C. with an alkali-metal hydroxide solution of aluminium and/or zinc oxide or hydroxide containing less than 15 per cent of alkali metal hydroxide calculated as sodium hydroxide.  The treatment removes the binding and encrusting substances between the fibres, such as pectins and lignin, and increases the flexibility of the fibres. The fibres may be treated before spinning or after they have been formed into ropes, yarns, fabrics, bags, or sacks.  Preferably, the treating solution contains 3-10 per cent of sodium hydroxide and the temperature of treatment is 80-100 DEG  C.  Temperatures above 100 DEG  C. may be used.  The time of treatment may be 1-2 hours.  The zinc or aluminium compound is preferably of a concentration at least equivalent to 0.5 per cent of zinc oxide or aluminium oxide calculated on the total weight of the solution. Solutions containing 1-3 per cent of zinc oxide and also 2-6 per cent of aluminium oxide may be used.  After the treatment with the alkaline solution, the fibres are squeezed and washed, preferably first with water, then with a dilute solution of hydrochloric or acetic acid, and finally with water.  The fibres may subsequently be treated with a mineral or other oil, preferably in emulsion form, to improve the flexibility of the fibres.  The oil may be spindle, rapeseed, cotton seed, castor or fish oil.ALSO:Yarns, ropes, fabrics, bags, sacks, and other articles made of crude Agave fibres, such as sisal or henequen fibres, or Manilla hemp fibres, are refined and rendered more flexible by treating them at a temperature of at least 60 DEG  C. with an alkali-metal hydroxide solution of aluminium and/or zinc oxide or hydroxide containing less than 15 per cent of alkali metal hydroxide calculated as sodium hydroxide.  The treatment removes binding and encrusting substances such as pectins and lignin.  The solution may contain 3-10 per cent of caustic soda and the temperature of treatment may be 80-100 DEG  C. or even above 100 DEG  C. The zinc or aluminium compound may be used in a concentration at least equivalent to 0.5 per cent of zinc oxide or aluminium oxide calculated on the total weight of the solution. Solutions containing 1-3 per cent of zinc oxide and also 2-6 per cent of aluminium oxide may be used.  After washing the fibrous material, the flexibility may be further improved by applying a mineral or other oil, preferably in emulsion form.  The oil may be spindle, rapeseed, cotton seed, castor, or fish oil.

Patent GB-593247-A (GB)
Title: Improvements in sheet feeding apparatus
IPC: B65H1/18
Filed: 1945-05-25
Abstract: 593,247. Feeding sheets. DEXTER FOLDER CO. May 25, 1945, No. 13171. Convention date, Oct. 26, 1944. [Class 100 (i)] In a sheet feeding' apparatus means for advancing the pile to feeding position is constructed with ratchet-operated mechanism which can be adjusted while the feed is running to adjust the level of the pile, the control means being operable from a clamp which engages the top of the pile under a sheet being separated and actuates electrical control means. The control mechanism comprises an oscillating arm 98, Fig. 3, having a roller 99 which swings in a path concentric with that of a sector-shaped cam-member 102 having its outer part circular and its inner part. formed of two circular parts 100, 101 of different radii. The arm 98 oscillates in unison with the swinging motion of a clamp or clamps 49 which are operated by swinging arms 40 controlled by a cam 36. The arms 40 give an up-and-down motion to the clamps, and a motion horizontally to-and-from the pile is given by a cam-groove 45 in a link 44 which is raised by the arm 40 and is fitted with an arm 48 in which the clamp 49 is mounted. The extent of movement of the arms 40 govern that of the arm 98 and if roller 99 descends far enough to engage part 101 of cam member 102 the cam is moved to operate the rod 111 of a micro-switch 115, and so energize an electro magnet which operates lever mechanism connected to the shaft 85 of a latch 84. This latch normally prevents actuation of a pileraising or advancing mechanism comprising a pawl 70 on a lever 71 connected to a camstrap 59 coacting with a cam 56. When the magnet is energized the ratchet-mechanism operates through gearing to move cords 17, 18 which raise a pile table 21. The angular position of the arm 98 on its shaft can be varied by a screw 109 to adjust the position to which the pile is raised. The automatic control of the pile may be thrown out and the mechanism set to advance the pile a regular amount for each sheet fed. The clamps 49 as shown are constructed to deliver a blast of air beneath the sheet which is being separated by suction devices 25, 51 acting on the rear edges of the sheets and serving to advance the sheets in overlapped or other condition to sheetforwarding devices. The mechanism may control the advance of a pile in a continuous feed mechanism, and hydraulic raising means may replace the ratchet means.
