Patent GB-1009892-A (GB)
Title: Alkylenedicyanamide polymers
Inventor: SUGINO KIICHIRO
IPC: C08G73/00
Filed: 1961-10-31
Abstract: Polymers are obtained by maintaining an alkylenedicyanamide of formula NC.NH(CH2)mNH.CN where m is an integer (e.g. 4 to 10), described in Specification 1,009,891, in the liquid state at a temperature in the range of from room temperature in the range of from room temperature to 100 DEG  C.  The alkylenedicyanamide may be melted, agitated for from 0.5 to 1 hour, cooled to below 40 DEG  C. and the liquid either allowed to stand at room temperature or heated again to below 100 DEG  C., until the mass solidifies. Alternatively, the alkylenedicyanamide may be dissolved in an alcohol or ketone, the solvent evaprated and the residue maintained at between room temperature and 100 DEG  C.  The polymerization may be accelerated by the presence of an amine, alkanolamine, quaternary ammonium base, quanidine or ammonia or salt thereof.  Examples are given. Specifications 549,368 and 549,392 also are referred to.
Patent GB-815280-A (GB)
Title: Method of producing nitro-starch
Inventor: ZIMMERMANN WERNER
IPC: C08B31/06
Filed: 1957-12-16
Abstract: Starch nitrate is produced by a method in which starch is dissolved in highly concentrated nitric acid and the resultant starch nitrates are precipitated in aqueous liquids containing nitric acid by introducing the nitrated starch solution thereinto in finely dispersed form, characterized in that the precipitation is effected by means of aqueous nitric acid containing no sulphuric acid, and having a HNO3 concentration above 40 per cent.  The process may be effected by dissolving potato starch, maize starch or the like, in at least 90 per cent concentrated nitric acid, a suitable proportion being 1:10, and allowing nitration to take place for a period dependent on temperature.  For producing a starch nitrate of minimum viscosity a temperature of 35 DEG  C. is suitable.  At the end of nitration, the solution is mixed with aqueous nitric acid free from sulphuric acid and having a concentration of, say, 50 per cent. Mixing may be effected either by stirring a thin jet of the nitrated starch solution into the vigorously agitated dilute nitric acid or by spraying the solution through fine nozzles disposed in the precipitation bath while the latter is vigorously stirred. Instead of a propeller blade stirrer, an apparatus which generates hydrodynamic vibrations, such as a "supratonator," may be used. The bulk of the acid is then separated from the precipitated nitrate in a centrifuge, cellular suction filter or pressure filter and recovered in the form of 50 per cent aqueous nitric acid which may be returned to the process.  The filtered product is washed in stages with nitric acid of progressively lower concentration and finally with water, the washing acids being returned to the process and their concentration raised to 50 per cent.  In the pure water stage, the starch nitrate is washed until neutral.

Title: Improved automatic let-off motion for the warp supply in looms
IPC: D03D49/06
Filed: 1960-11-14
Abstract: 914,197. Warp beam let-off mechanism. RUTI MACHINERY WORKS Ltd. Nov. 14, 1960 [Nov. 13, 1959], No. 39103/60. Class 142 (2). In a positive driving mechanism for a warp beam wherein the tension of the warp controls the let-off, the beam 46 (Fig. 1) is gear-driven from a worm 35 and wheel 36, the mechanism incorporating a ratchet 39 and a ratchet mechanism 30-34 which is driven by a reciprocating rod 27 whose stroke is variable and controlled by the warp tension. In Fig. 1 a shaft 3 with an adjustable throw eccentric 10 reciprocates a rod 12 which is connected by a link 14 to a slide 16 movable on an arcuate guide 18. The back rest 25 is pivoted and connected by a cable 21 to a pivoted link 20 which moves the slide 16. When the warp is slack the cable 21 lowers the guide 16 to the chain-dotted position and the eccentric 10 moves the rod 12 mainly up and down so that little reciprocation is given to the rod 27 and thus the ratchet 30-34 is not operated and no warp is let off. As the warp tension increases the cable 21 raises the guide 16, greater reciprocation is given to the rod 27, ratchet 30-34 and the warp is let off. In Fig. 6 a cam-track 168 reciprocates a lever 164 and the cable 21 acts directly on the guide 16 to vary the stroke of the rod 27. In Fig. 7 a rod 221 (in place of cable 21) moves a lever 220 about a pivot 219 to move the guide 216 and in Fig. 9 the guide 316 is pivoted at 319 and moved therearound by the rod 221 to vary the stroke of the rod 27. German Specification 869,324 is referred to.

Abstract: 902,667. Preventing corrosion. PREISER, H. S. Dec. 5, 1958, No. 39271/58. Class 123 (1). An impressed current D.C. energized anode system for protecting a ship's steel hull from corrosion comprises a D.C. generator 6 having its negative terminal 8 grounded through a three-way switch 14 and its positive terminal 10 connected by a flexible waterproof cable 12, e.g. 200 feet long, to an electrochemically insoluble anode 11 which has a weight per foot corresponding to that of the cable 12 for trailing at least 500 anode diameters away from the ship. The switch 14 can be operated to connect the hull 5 through terminals 15, 16 to forward and stern electrodes 17 and 18 of a reference voltameter to measure the oxidation reduction potential, and thus the corrosion resistance, of the hull 5. Polarization occurs accompanied by the formation of a protective coating of calcium carbonate precipitation on the hull 5. An anode, Fig. 3, comprises a silver rod 11 which is clad with a 0.005 inch thick layer of pore-free platinum and is soldered at 25 to a conductor 24 of the cable 12. The joint is sealed by a rubber sheath 27 and a thermoplastic covering 28. Vanes and stabilizers may be fitted to an anode. As shown in Fig. 4, a cable 46 wound on a reel 44 mounted on the deck 40 of a ship 30 and passing through a rubber or plastic lined pipe 38, having gate valves 50, into the sea, carries a trailing anode rod 48. An anode rod, Fig. 5, not shown, comprises a silver or copper rod which is threaded at one end for attachment to a cable and has a non-porous coating of tantalum or titanium of about 0.010 inch thick and a very thin layer of platinum or palladium of about 0.00025 inch applied as a cladding or plating. A variable weight hollow rod is described which is closable by end plugs and can be filled with the desired amount of ballast such as plastics and sand. In a further modification, Fig. 7, a conductor of the cable 74 is soldered to a cylindrical tantalum connector so that the other end of which has a threaded recess for attachment to a trailing anode 76. The joint is covered by a tapered rubber sleeve and a twopart screw-engageable collar 84, 90. An arrangement, generally similar to that shown in Fig. 7, may be adapted for a cable having a central steel core.
