Title: Production of isocyanates
Filed: 1954-04-14
Abstract: In a process for the production of organic isocyanates by reacting a salt of a primary amine with phosgene in the presence of an inert diluent, the reactants in the presence of said diluent are passed in a continuous stream through a tube heated to a temperature of at least 50 DEG  C.  Amine hydrochlorides may be employed as starting materials, e.g. in mixtures with carbamyl chlorides obtained by reacting phosgene with amines or certain amine salts such as carbaminates in the presence of an inert diluent.  In the apparatus in the drawing a primary amine salt phosgene and an inert diluent are passed optionally through preheater 1 to the bottom of tower 2 with additional phosgene if desired and the reaction is completed in tower 3 with additional phosgene and the isocyanate is distilled from the reacted mixture leaving the top of tower 3.  Vapours <PICT:0761594/IV(b)/1> leaving towers 2 and 3 are condensed in coolers 4 and 5 and returned to the bottoms of the towers.  In examples: toluylene diisocyanate is obtained by mixing toluylene diamine, phosgene and o-dichlorobenzene and passing the product through the apparatus described (1); naphthalene 1,5-diisocyanate is similarly prepared from 1,5-naphthalene diamine (2); p-ethoxyphenyl isocyanate is similarly prepared from p-phenetidine using chlorbenzene as solvent (3); octadecane-1-isocyanate is similarly prepared from octadecylamine-1 (4); a -naphthylene isocyanate is similarly obtained from a -naphthylamine (5).  The products are worked up by distillation after removal of dissolved phosgene by blowing with nitrogen.  Specifications 761,590 and 761,592 are referred to.

Title: Method and apparatus for the treatment of textile fibres
IPC: D02G1/00
Filed: 1972-05-12
Abstract: 1385700 Crimping protein fibres I W S NOMINEE CO Ltd 12 May 1972 [20 May 1971] 11236/74 Divided out of 1385699 Heading D1F A method of crimping protein e.g. wool, fibres comprises applying an aqueous solution of an alcohol to the fibres, drafting the fibres and subsequently relaxing the fibres to form crimped fibres. The fibres are preferably treated in the form of non-twisted top, sliver or roving. The relaxation treatment may be carried out on the top, sliver or roving, on a yarn spun from the top or on a fabric made from the yarn. The aqueous solution preferably contains 10-50% by volume of alcohol which may be n-propanol, isopropanol, methanol, ethanol, n-butanol or isobutanol. The aqueous solution may also contain an acid e.g. formic or acetic acid, or may contain an alkali e.g. ammonia. The boiling point of the acid, alkali or alcohol is preferably less than 120‹C. A setting agent and a cross-linking agent may also be added to the aqueous solution. In a preferred embodiment, a top of keratin fibres W is passed through a vacuum padder A containing the impregnating liquid and is then passed into a U-tube B where the top is allowed to dwell to ensure uniform impregnation. The top is passed through the tube B on a conveyor 29 and is taken out by tension controlling rollers 33, 34, 35 to pass through a drafting chamber C. The walls of the tube B are kept cool by liquid circulating within the walls. The top is drafted by 10-30% between nip rolls 38, 39 and is then conveyed by rolls 40, which may rotate at the same surface speed as rolls 39 or at a lower speed, to a setting chamber D. The top is set by means of steam jetted in by pipes 50 and is conveyed on a mesh belt 44 to a drying chamber E. The setting chamber D is maintained at a temperature of 80-125‹C by a heater 51. The top is then conveyed through a similar drying chamber E without being subjected to steam treatment, the chamber E being maintained at a temperature of 80-110‹C. The dried top is then cooled at F and conveyed to be worked up into yarn. In the process for direct crimping of protein fibres, the top is steamed and dried under no applied tension, the conveyor belts 48, 48' being in an upper position as shown in solid lines in Figure 2. In this case, the rollers 40 are rotated at a slower surface speed than the rollers 39 whereby the top is overfed to the rollers 40 and the crimp in the fibres appears. In the process for indirect crimping of protein fibres, the rollers 40 are driven at the same speed as rollers 39 to maintain the top under tension and the top is steamed and dried while tension is maintained by means of the conveyor belts 48, 48' which are lowered into the position shown in doffed lines. The fibres are relaxed in yarn or fabric form by means of dyeing or finishing treatments using steam or boiling water. Several numerical examples are given.

Title: Improvements in and relating to electric traction systems
Inventor: COLLINS GORDON
IPC: B60L7/12
Filed: 1958-04-09
Abstract: 875,960. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 9, 1958, No. 11248/58. Class 38 (3). During regenerative operation of traction motors A1-A4, a resistor RL is adapted to be connected across the armature circuit by a highspeed contactor having a coil B, so preventing damage to the motors if the power supply lines become non-receptive to the regenerated energy. The coil B is connected in series with thyratrons T1, T2, across the armature circuit, and, if the rate of increase of the armature voltage exceeds the charging rate of capacitor C2, the thyratron T2 will fire at a comparatively low value of the armature voltage, so that thyratron T1 will also fire to energize the coil B. If the rate of increase of the motor armature voltage is relatively slow, due to partial receptivity of the supply during regenerative operation, both capacitors C1, C2 will be ineffective and the thyratrons will fire only when the armature voltage reaches a comparatively high value. Energization of the coil B causes rapid operation of the contactor by the neutralization of the holding flux produced by winding H, whereby the shunt field circuit is de-energized and the line switches are opened. Specifications 817,044 and 875,959 are referred to.
