Title: Preparation of polyamides
IPC: B01J19/24
Filed: 1965-02-15
Abstract: <PICT:1093451/C3/1> A polyamide is produced continuously from an aqueous solution of a salt of a diamine and a dicarboxylic acid by passing the solution through a series of two reactors, steam being allowed to escape from the second reactor and extruding the molten product.  Any variation in the rate of throughput of polyamide is compensated by a parallel change in the initial solution concentration and an inverse change in the pressure in the second reactor, whilst the residence time and temperature of the polymer between the second reactor and the extruder is kept constant so that the viscosity and the number of amine end-groups of the product are unchanged. The polyamide may be poly (hexamethylene adipamide).  In an embodiment of the invention the salt solution is fed into first reactor 10 at 18 from a still (not shown) where its concentration can be preadjusted to 50-70% by removing water from a less than 50% solution.  In the first reactor the solution is heated by vapour jacket 20, any eliminated water-vapour escaping at valve 8. From the first reactor it is propelled by pump 24 through 12 and 14 which together constitute the second reactor, vapour jackets 26 and 48 supplying the heat.  In 14 steam escapes at valve 69 and screw 66 squeezes vapour bubbles out of the melt before propelling it through equilibration unit 70.  In the equilibration unit the melt may be conducted through either of the conduits 74 each of which is of different width so that its residence time remains at a particular constant value independent of throughput.  Fig. 2 (not shown) represents an alternative equilibration unit in which the unit (78) may be replaced by one of different pipe volume placed across the gap (752).  The melt is extruded at 38 by gear pump 36.  Variations in the gear pump velocity may be preceded by variations in the input concentration and steam pressure in that order.

Title: Improvements in, or relating to, the excitation of continuous current generators
IPC: H02P9/24
Filed: 1928-03-03
Abstract: 286,606. Allmõnna Svenska Elektriska Aktiebolaget. March 5, 1927, [Convention date]. Exciting; regulation of exciting machines. - In an exciting arrangement for a self-escited continuous-current dynamo-electric machine involving a voltage regulator of the type which periodically causes an independent source of voltage to act in different. ways on the excitation of the machine, the connection between the primary independent source of voltage of the exciting winding energized thereby is effected through movable regulator contacts without short-circuiting any portion of the exciting winding so as to cause a reversible voltage source to be connected in series with the self-excited winding of the main machine. In Fig. 1, 1 is a, continuous-current generator which may excite an alternator, and in series with the field 2 are resistances 3, 4. The junction of the resistances is connected to one terminal of an auxiliary generator 7 constituting a primary independent source of voltage. the other terminal of which is connected to contacts 5, 6 periodically operated in such a way that the voltage acting on the field coil 2 is either the sum or the difference of the voltages of the machine 1, 7. In a modification, Fig. 3, two exciting coils 8, 9 are employed and the arrangement is such that when the contacts are closed, the machine 1, 10 each excite one winding and both windings act in the same direction, but when the contacts are open. the two machines are in opposition and further, the field windings oppose each other. In another modification, Fig. 5, an auxiliary machine 16 is permanently connected in series with the field winding 15 and is excited in one direction or the other by windings 17, 18 connected alternately through an oscillating contact 20 to an exciter 19 constituting the primary inaependemt voltage source. The machines 16, 19 mav be driven by one or more motors 21, 22 fed with alternating current from the main. generator 13, 14 so that their speeds and consequently their voltage will increase with the voltage of the main generator. In Fig. 6, the auxiliary machine 16 has a single exciting winding 23 fed from an exciter 19 through simultaneously operated vibrating contacts 25. A resistance 24 is connected in shunt with the field 23 to facilitate the change over in the event of one of the contacts 25 opening before the other closes, and resistances 26 are connected in series with the contacts for preventing short-circuiting if both contacts should remain closed at the same time. The arrangement of Fig. 6 may be modified by connecting the exciter 19 to a, potentiometer and connecting the coil 23 at one end to the mid point of the potentiometer and at the other end through a vibrating contact to one or other of the machine terminals. Specifications 17739/09, and 250,257, [Class 38 (iv), Electric supply and transmission systems &c.], are referred to.

Abstract: 655,472. Electroplating rod material. KENMORE METALS CORPORATION. March 8, 1948, No. 7137. Convention date, March 6, 1947. [Class 41] [Also in Group XXII] Apparatus for treating rod material such as heavy gauge wire having a diameter of at least 0.075 inches, comprises coiling means operable to form the wire continuously into a helical coil in which the individual turns of the helix are of uniform diameter, holding means operable to maintain the individual turns of the helix to uniform size and to simultaneously and continuously rotate the helix to feed it horizontally and longitudinally with respect to its own axis, and a liquid-treating means for said wire, comprising a tank disposed below the helix holding means and adapted to surround at least a portion of each of a plurality of said helical turns which are adjacent to each other. As shown in Fig. 4, the wire is first straightened by being passed between pairs of vertical and horizontal rollers 22, 23 and is then coiled by being passed between grooved rollers 61, 62 and under an adjustable roller 67. The wire is then gripped between a driven roller 10 and a pressing roller 15 and fed in the form of a helix into and through several baths shown in Fig. 1, namely a cleaning bath 39, two cold water rinsing baths 40, 41, an acid bath 42, cold water rinsing baths 43, 44, an electroplating bath 45, a cold water washing bath 46, and a warm water washing bath 47. To obtain coils of uniform diameter the speed of travel of the wire may be regulated by means indicated in Fig. 8. Contacts 24, 25 are placed near the bottom of one of the coils of wire. If the coil becomes large enough to engage the contact 25 a servomechanism 27 and speed-adjusting means 28 are electrically operated so that the speed of drive of the wire is reduced. On the other hand, if the coil touches the contact 24 the speed will be increased. In a modification, the apparatus is adapted to deal with two wires at the same time. The wire may have several coatings of the same or of different metals. Specification 645,834 is referred to.
