Patent GB-837120-A (GB)
Title: Trimerisation of organic isocyanates
Inventor: TATE FRANCIS EDWARD GERVASE
Filed: 1957-06-12
Abstract: Organic isocyanates are converted into their trimeric iso cyanurate form by contacting them with at least one organic base containing an hydroxyl ion.  Such bases may be quaternary hydroxides derived from nitrogen, phosphorus, arsenic or antimony or a ternary hydroxide derived from selenium or sulphur. Temperatures from -10 DEG  C. to the decomposition temperature of the catalyst may be used.  Inert solvents may be present.  The polymerization may be inhibited at any stage by addition of an acidic substance such as HCl, acetic acid or acetyl chloride. Unchanged monomers may be separated from the trimer by distillation or by precipitation of the polymer from a solution of the mixture by addition of a non-solvent for the polymer. Examples describe the trimerization of phenyl isocyanate, p-tolyl isocyanate, p- and o-methoxy phenyl isocyanates, p- and o-chloro phenyl isocyanates, p-nitro phenyl isocyanate, 2 : 4-toluene di iso cyanate, chloro phenylene-2 : 4-di-isocyanate and n-hexadecyl isocyanate, the reactions generally being carried out in dimethyl sulphoxide using tetraethyl ammonium hydroxide, benzyl triethyl ammonium hydroxide, trimethyl sulphonium hydroxide, tetraethyl phosphonium hydroxide or tri-a  : a 1-di-pyridyl ferrous dihydroxide as catalyst.  Numerous other monomeric isocyanates are mentioned including 3 : 31-dimethyl-4 : 41-di-iso-cyanato-diphenyl methane, 4 : 41-diisocyanato-diphenyl ether, naphthylene-1 : 5-diisocyanate, hexamethylene diisocyanate, diisocyanato-di-cyclohexyl methane, toluene-2 : 4 : 6-triisocya-nate and 2 : 4 : 41-triisocyanato-diphenyl.  The trimers and their reaction products with phenols, diphenylamine, aceto acetic esters and malonic esters may be used as curing agents for resins (see Group IV (a)).

Title: Improvements in connection with machines for wrapping sweetmeats and other articles
IPC: B65B35/20
Filed: 1922-07-07
Abstract: 199,953. Rose, W., and Rose Bros. (Gainsborough), Ltd. July 7, 1922. Packeting by wrapping-up; feeding sweetmeats &c.-Relates to apparatus in which sweetmeats &c. are pushed in succession from a conveyer into a wrapping- machine, or other required position. According to the invention, the conveyer travels continuously and the articles are pushed therefrom by a pusher so operated that it follows the movements of the conveyer during its forward stroke, moves clear of the conveyer, and returns to its original position. As shown, a conveyer chain 1, Fig. 1, travels continuously round sprocket wheels 2, 2<a> and carries members 4 which forward the articles along a channel 5. A pusher 9 is operated by a cam 16 to push the article laterally from the conveyer and by a cam 34 acting on a lever 28, 32 to follow the movement of the conveyer during its forward stroke. The article arrives in a, runway 22, Fig. 2, beneath a retaining-finger 44 and is pushed to the left by a plunger 23 to a position beneath a retaining-finger 49. A third plunger 54 pushes the article, which may carry with it a wrapper, into a recess 52 of the mould wheel 53 of a wrapping-machine, or other required position. The plunger 23 remains in its forward position sufficiently long to act as a guide for the article during its transference from the runway 22.

Title: Improvements in and relating to dyeing with vat dyestuffs
IPC: D06P1/22
Filed: 1929-06-19
Abstract: Vat dyes, dyeing with.-The harmful effect of alkali in dyeing animal or other fibres with vat dyes is eliminated by the addition of boric acid to the alkaline vats before, during, or after the reduction, in such a quantity that the alkalinity is reduced but not entirely neutralized.  In carrying the invention into effect, the dyestuff may be vatted with the customary amounts of soda and hydrosulphite, the boric acid being subsequently added, or the fabric may be padded with a suspension of the unreduced dyestuff, and then treated in a bath containing alkali and hydrosulphite, to which boric acid has been added.  With some dyestuffs, particularly with Caledon red BN and Caledon red violet 2RN, boric acid is added until the colour of the vat changes, apparently from that of the sodium salt to that of the free leuco compound; with other dyestuffs, the amount of boric acid added must be less than that required to produce this colour change. Examples are given of the dyeing of wool in vats made up with the following dyestuffs and various amounts of boric acid.-Caledon blue 3RK, red BN, FF, 5G, red violet 2RN, brilliant violet R, jade green, yellow 3G, and olive R, Helindone brilliant yellow G, and Indanthrene brilliant violet BBK, yellow RK, 3RT, 5GK, yellow brown 3G, grey K, BTR, 6B, red GG, BK, brown FFR, violet BBK, blue 5G, brilliant orange RK, GK, scarlet B, pink B, brilliant pink B, R, red brown 5RF, and olive 3G.  Further examples illustrate the dyeing of wool with a mixture of Caledon brown R and Caledon red violet 2RN, of cotton with Caledon red violet 2RN, of silk with Caledon red BN, and of viscose silk with Caledon red BN.  In another example wool is dyed in a bath prepared from Caledon red BN, the boric acid being added to the bath before the hydrosulphite.  In an example of the padding process, wool is padded by passage through a padding mangle containing a suspension of Caledon red BN in water, to which Prestabit Oil V has been added, the cloth being subsequently treated in a bath containing soda, hydrosulphite, boric acid and Glauber salt.

Abstract: 958,205. Cigarette-making machines. MOLINS MACHINE CO. Ltd. June 2, 1960 [June 3, 1959], No. 19060/59. Heading A2C. A continuous rod cigarette making machine in which surplus tobacco is removed from the filler by a trimming device, is provided with means to detect variations in the quantity of surplus tobacco. In Fig. 1 surplus tobacco is removed from a filler, held by suction on a conveyer 1, by trimming knives 3 and a brush 4, the removed tobacco 7 being received in a shaking conveyer 5 which feeds it to a second conveyer 8 for return to the tobacco feed means. The thickness of the stream of surplus tobacco 7 is measured by a pivoted feeler 9; variations of more than a predetermined amount cause closing of a switch 16 or 17 to drive a reversible motor 19 in one direction or the other to adjust a variable pulley 26, thereby varying the speed of the drive shaft of the tobacco feed hopper 31 to adjust the tobacco feed. In a modification, Fig. 2, the thickness of the surplus tobacco stream is measured by the pressure variations in a suction box 42 drawing air therethrough, which pressure variations cause a bellows 45 to control a hydraulic pump and motor circuit 51 driving the tobacco hopper shaft 54. In Fig. 3 the quantity of surplus tobacco is measured by the pressure variations in an air stream drawn through the portion of the filter below the level of the trimming discs 3 by a suction tapping 63, the pressure variations controlling the tobacco feed as in Fig. 2.
