Patent GB-617929-A (GB)
Title: Production of glycerin and distilled fatty acids
IPC: C11C1/04
Filed: 1946-07-30
Abstract: Fatty acids and aqueous glycerine are produced by subjecting glyceride fats or oils in the presence of a water-insoluble metal soap as hydrolysis catalyst, to hydrolysis with a countercurrent flow of water at elevated temperature and pressure.  The resulting hot fatty acids are freed from dissolved water by vaporization and the dried acids, which contain the catalyst and are still hot, are subjected, promptly and without intermediate cooling, to distillation under subatmospheric pressure with the aid of further heat.  A substantial proportion of the catalyst-containing residue which remains after distillation is returned to the stream of fat entering the hydrolysis reaction, that portion, if any, of the residue which is not so returned being, if desired, washed with dilute mineral acid such as sulphuric acid for the removal of the metal of the catalyst and the production of low grade fatty acids.  The hydrolysis process may be initiated with fresh catalyst and the operation of the process continued for a considerable time without any addition of fresh catalyst, all the distillation residue being recycled. Alternatively, a constant proportion of distillation residue may be eliminated, there being a constant small addition of new catalyst.  The hydrolysis catalyst employed may be a soap of calcium, magnesium, zinc, lead, aluminium or titanium.  In an example, tallow is hydrolysed with water in the presence of the zinc soap of tallow fatty acids and apparatus is shown for the hydrolysis reaction, the distillation of the fatty acids and the recycle of the distillation residue.  Specification 617,930 and U.S.A.  Specifications 2,156,863, 2,267,750 and 2,274,802 are referred to.

Abstract: 1357493 Making wire; drawing SUMITOMO ELECTRIC INDUSTRIES Ltd 16 May 1972 [17 May 1971 7 July 1971 16 Dec 1971 (2)] 23026/72 Headings B3A and B3P A method of separating metallic filaments 1<SP>1</SP> forming the core of a drawn composite wire 4<SP>1</SP> from a surrounding metal tube comprises reducing the thickness of the tube at two different longitudinal peripheral portions, applying a compressive force to the unreduced portions to divide them from one another. A bundle of wires is surrounded by a metal tube to form a composite wire which is drawn to reduce the diameter of the wires to form filaments. The drawn composite wire 4<SP>1</SP> is pulled through cutters 14 of a cutting device 6 to cut two sides of the metal tube, and then passed through a guide 7 and rolls 8, the latter breaking the cut sides of the tube so that upper and lower portions of the tube can be coiled on spools 12, 13 while the separated filaments are coiled on a spool 11. Metallic bonding of the wires is prevented by coating them with a separator. Separators described are powders of pyrophillite minerals, e.g. talc; montmorillonite minerals, e.g. bentonite, acid clay or fuller's earth; kaolinite minerals, e.g. kaolinite, nacrite or deckite; and porous minerals, e.g. diatomaceous earth. The coating of a separator on the wires is effected by passing the wires through a mixture of the separator; a binder, e.g. methyl, carboxymethyl, or hydroxyethyl cellulose, polyvinyl alcohol, glycerine, starch or dextrin, and a liquid, e.g. water. In some examples the separator was omitted and the wires covered in a thin layer of oxide.

Abstract: 224,508. Singer Manufacturing Co., (Assignees of Chason, D. H.). Nov. 8, 1923, [Convention date]. Locks, with bolts interlocking with staple; cases for square key and like.-A lock is operated by a disc having eccentric slots engaging pins or a pair of hook-ended bolts and operated by a flat key which, when turned, causes the bolts to slide outwards to interlock with the staple. The casing is made in two halves 5, 6 stamped from sheet metal and made with guides 8, 11 for the bolts 10, and a seating for the operating disc 13. The halves are secured together by lugs 22 being bent over slots 24 and tongues 4 entering recesses in the end plate 1. The bolts 10 are fitted in the casing with their lower parts 9 in the guides 8 and their shanks 10 in the guides 11, the disc 13 being placed between them so that a pin 16 on each bolt enters one of the eccentric slots 14 in the disc. In the unlocked position, shown in Fig. 4, the pins 16 are at the extremities of the slots 14. To lock, the staple plate 27 is brought over the protruding ends of the bolts and the disc 13 turned by a flat key 21 the end of which engages a correspondingly-shaped hole 17 in the disc. This causes the bolts to move outwardly so that their hook-ends 12 engage over the edges of the hole in the staple, bringing the pins 16 into the inner ends 15 of the slots 14. The inner ends 15 of these slots are concentric so that a pull on the keeper or staple 27 will not tend to rotate the disc to release the bolts. The bolts have. clearance holes 18 for the key, and the front half 5À of the cover has a hole 20 necessitating cutting away of the key to permit its rotation and preventing removal of the key except in the shot position of the bolts.

Abstract: 1393066 Sensing package growth to control winding speed; maintaining traverse guide at surface of package OWENS-CORNING FIBERGLASS CORP 15 May 1973 [15 May 1972 29 Dec 1972] 23182/73 Headings D1F and D1J As a yarn package grows in diameter its size is intermittently sensed, there being control means responsive to said intermittent sensing to (a) operate drive means displacing a support for a traverse guide to maintain the guide at the surface of the package (b) reduce the speed of rotation of the package to maintain a uniform linear collection rate. In Fig. 4 a barrel cam 66 causes a strand guide 60 to traverse the linear material 22 across the package 42. A spring 80 presses the strand guide 60 against the package. As the package increases in diameter the spring 80 is deflected until it reaches the setting shown in broken lines. A housing 64, surrounding the barrel cam 66, carries a normally open magnetically actuated reed switch 136. The spring 80 carries a magnet 140 and when the spring 80 is deflected to the broken line setting the traverse path of the magnet 140 is sufficiently close to the setting of the reed switch 136 as to cause it to close. Closure of the reed switch 136 causes a motor 120, Fig. 5, to be energized. Rotation of the motor 120 causes (a) a screw and nut assembly 122, 124 to rock an arm 62 carrying the barrel cam 66 and its housing 64 away from the package surface until such time as the spacing between the magnet 140 and the reed switch 136 is sufficient for the reed switch to open and (b) rotation of a potentiometer 160 that varies the output speed of an eddy-current clutch transmitting power from a drive motor to the collector on which the package is being built. The change in speed of the package is such as to maintain a constant rate of wind-up. According to the description the magnetically controlled switching means can be replaced with a light sensitive switching arrangement, a high frequency energy beam or a pneumatic arrangement.

Title: Improvements in the manufacture of cellulose esters
Inventor: FISHER JAMES WOTHERSPOON
IPC: C08B3/22
Filed: 1954-08-10
Abstract: Cellulose esters of organic acids having a degree of substitution of 2.25-2.6 are subjected in solid particulate form to the hydrolysing action of an aqueous solution of an acid having a degree of ionization of at least 0.1 measured in normal solution at 18 DEG  C. until their degree of substitution has been reduced to 0.8-1.9.  The acid may be sulphuric, hydrochloric or nitric, preferably nitric. The concentration of the acid preferably does not exceed about 12 per cent and may with advantage be about 1-10 per cent.  The acid temperature may be 15-75 DEG  C.  In an example, a cellulose acetate of acetyl value 53.9 per cent (as acetic acid), dried and ground to pass a 30-mesh B.S.S. screen, is immersed in about 8 times its weight of a 7.5 per cent (by weight) solution of nitric acid at 25 DEG  C. for 16 hours, the nitric acid run off and the cellulose acetate washed.  It has an acetyl value of 46.3 per cent.  If the ripening period is increased by 8 hours the acetyl value is reduced to 40.8 per cent.  By using higher temperatures and longer ripening periods acetyl values as low as 27 may be obtained.  The products are soluble in acetone-water mixtures, can be moulded, and are more stable than the original cellulose acetates.
