Title: A process for the manufacture of waterproof products from animal fibrous material
IPC: C08L89/06
Filed: 1935-05-07
Abstract: 456,726. Waterproofing. FREUDENBERG GES., C., Weinheim, Baden, Germany.- (Assignees of El÷d, E. ; Karlsruhe, Baden, Germany) May 7, 1935, No. 13491. Convention date, May 7, 1934. [Classes 76 and 140] Shaped products, e.g. sheets, made in known manner by extruding or rolling swollen and disintegrated animal fibrous material, are rendered waterproof, permanently soft and elastic. by treatment first with swelling agents, if desired in the warm, and then with waterinsoluble softening agents such as castor oil, paraffin oil or train oil. Tanning may be effected before, during or after softening and a water-resistant coating, e.g. of cellulosic lacquer may be finally applied. Untanned products are swollen with glycerine or a mixture of glycerine and an organic solvent such as methyl alcohol. Alternatively, the products are swollen with water which is then removed by expressing between felts and then treating with water displacing liquids such as acetone or alcohol. If desired the products may be further treated with glycerine or glycerine and methyl alcohol. Tanned products are softened by immersion in glycerine containing a little water with or without alcohol. In all cases the swelling agent is preferably re. moved before softening, e.g. by treatment with alcohol and heating. Tanning may be effected during softening by alum dissolved in glycerine or chromium chloride dissolved in alcohol. Cellulose derivatives may be incorporated in the products, e.g. together with the softening agents.

IPC: C01F5/22
Filed: 1962-04-14
Abstract: Magnesium hydroxide is prepared by a continuous process which comprises slaking dolomitic lime with water at a temperature between 37 DEG  C. and the boiling point of the slaking mixture for at least 90 minutes, mixing the slaked lime slurry with magnesium chloride brine under high shear mixing conditions at a temperature of from 37 DEG  C. to the boiling point of the slurry for a period of two to twelve minutes, and filtering and washing the said slurry to recover Mg(OH)2, the mixing with brine being carried out within 180 minutes prior to the commencement of the filtration and washing step. High shear mixing is effected using a rotary agitator, the tip speed of which is at least 1000 and preferably from 1000 to 4000 feet per minute.  After the treatment with brine, the mixture may be hydraulically classified.  As <PICT:0972323/C1/1> shown, dolomitic quicklime from bin 10 is slaked with water from tank 16 in vessel 14, and the slurry is fed to tank 26 prior to entry to reactor 32, where it is reacted with brine from tank 34. The reaction mixture is passed through classifier 46 to remove heavy impurities before entering the filtration tank 50. Magnesium hydroxide is collected off the drum 54 and dried in chamber 60, before packaging or further treatment, e.g. calcination to magnesium oxide.

Abstract: 725,613. Feeding webs. BRITISH TABU. LATING MACHINE CO., Ltd. May 20, 1953, No. 14171/53. Class 100 (1). [Also in Group XIX] A data bearing tape is fed past a magnetic sensing head or photo-electric device by two pairs of rollers one pair being stationary and the other pair constantly running with one roller of each pair being carried on a rockable member arranged to grip the tape between one or other of the pairs of rollers to stop or start the tape rapidly. A tape 2, Fig. 1, passes between stationary rollers 5 and 6, over a guide plate 8, and between a pair of constantly running rollers 3, 4. The tape is guided by freely revolving rollers 9 and a free loop of tape is provided between the pairs of rollers and the supply and take-up spools which may be driven in known manner by servo mechanisms controlled by the loop positions. The rollers 4 and 5 are mounted at the ends of two arms of a rocker 10. The rocker has two further arms which carry extensions 11 and 12 which form the armature for a. start electromagnet 13 and a stop electromagnet 14. The rocker is pivoted on a stud 15. The lengths of the arms of the rockers is such that for a given movement of the armatures, the rollers move through twice the distance. When the stop magnet 14 is energized the extension 12 tends to move so that it is opposite the core of the magnet and this movement forces the rollers 5 and 6 together, and holds the rollers 3 and 4 apart, keeping the tape stationary. Similarly when the start magnet 13 is energized the tape is released from the stationary rollers and gripped between the constantly running rollers 3 and 4. The movement between rollers 4 and 5 necessary to grip the tape is small so that the gears 18 and 19 which transmit the drive from shaft 17 to the lower driven roller 4 remain in mesh irrespective of the position of the rocker 10. The block 16 carrying the stud 15 is adjustable by means of a screw 20 in a fixed block 21, so as to accommodate different thicknesses of tape. A magnetic reading head 22 is mounted on a plate 23 which is also adjustable so that the distance of the reading head from the tape may be adjusted. A photo-electric head may be provided in place of the magnetic tape if punched tape is provided in lieu of magnetic tape.
