Title: Exothermic reaction processes
IPC: C08F210/18
Filed: 1974-01-10
Abstract: 1449345 Cooling reactions by vaporisation; polymerisation apparatus E I DU PONT DE NEMOURS & CO 10 Jan 1974 [11 Jan 1973] 01258/74 Heading B1X [Also in Division C3] In a process for bringing together at least two reactants which react exothermically, at least one of which is more volatile than the product of the reaction or any diluent, and wherein the reaction is cooled by vaporisation of at least one reactant and the vaporised reactant is subsequently condensed and returned to the reaction vessel, the reaction is carried out in at least two sequential reactors in which at least 10 weight percent of the product is formed in each reactor, and at least a portion of the vaporised reactant from at least one downstream reactor is directly returned to at least one upstream reactor. As discribed in connection with the preparation of ethylene-propylene-1, 4-hexadiene terpolymer, using VCl 4  and di-isobutyl AlCl catalyst, in reactors 1 and 19, a part of the product stream from reactor 1 passes to compressor 10, condenser 11 and separator 12 from which condensate is returned to the reactor via line 3. Remaining vapour gas to compressor 13, condenser 14 and separator 15, from which part of the condensate is returned to reactor 1, the remainder to reactor 19, and uncondensed gases are partly recycled and partly discharged. The remainder of the product stream from reactor 1 goes direct to reactor 19. Part of the vapour phase in reactor 19 is fed back to the liquid zone in reactor 1 by line 26; a further part is added to the stream from reactor 1 to the compressor.

Title: Improvements in or relating to Control Systems for Electric Motors.

Abstract: 1,191,391. Control of D.C. motors. LANSING BAGNALL Ltd. 8 Jan., 1969 [9 Jan., 1968], No. 1304/68. Heading H2J. [Also in Division G3] A D.C. motor is energized by pulses which are initiated when the armature current is below an adjustable predetermined value, as detected by an arrangement coupled to a voltage divider, part of which comprises an element whose impedance varies according to magnetic flux through it, the flux being produced by a conductor carrying the armature current. The element consists of a Hall device MR1 and a winding 11 for the current; assuming this is already flowing, when it is high enough to cause a transistor TR1 to conduct capacitor C4 is charged until its voltage is sufficient to cause conduction of further transistors TR4, TR5 to thereby trigger a thyristor TH2 and so produce a triggering pulse for a " turn off " thyristor (22, Fig. 1, not shown) in the motor circuit. This terminates a pulse and the armature current decays through a flywheel diode until the impedance of the Hall device drops sufficiently for TR1 to turn off; this allows a transistor TR2 to turn on to trigger a thyristor TH1 which in turn triggers an " on " thyristor (17) in the motor circuit and so start a new pulse and hence repeat the cycle. The time constant of C4 determines the minimum pulse length. The effective value of the armature current, and hence the motor speed, is varied either by a bias signal in a winding 31, by movement of a permanent magnet 33, by varying the otherwise constant voltage (which may be direct or alternating) applied to the Hall device by making resistor R2 adjustable, or by varying the threshold level of TR1. The motor is a series machine having separate forward and reverse field windings and in Fig. 3 (not shown) separate control circuits are provided for each direction, with an interlocking cross-connection.

Abstract: 246,176. Vulkan Maschinenfabriks-Akt.-Ges. Jan. 17, 1925, [Convention date]. Combined turning, drilling, milling, and planing machines. - A combination metal-cutting machine tool comprises a vertical housing 1 containing the driving mechanism for the various units which are arranged around the housing and are all operated at the normal height. The lathe bed 9, carrying a tailstock 12 and slide rest 10. is mounted on the right, Fig. 1. of the housing, while on the left is mounted a vertically adjustable table 2 having a transverse slide 3 and work-table 4. An adjustable overhanging arm 5 connected to the upper part 1<a> of the housing carries on one side a fixed drilling spindle 7 and on the other a tool slide 6 which for planing operations receives a cross feed movement operated from the table 4. A fixed milling spindle, 8 is mounted parallel to the lathe spindle. A main shaft 16, driven either by an electromotor 14 or from belt-pulleys 15. carries a pulley 18<1> which drives a pulley 18 on a countershaft 17, geared to a sleeve on the lathe spindle 19 through change speed gearing arranged to give six spindle speeds. By the use of further pairs of sliding gears an additional four speeds may be obtained. The sleeve is connected to the spindle by a sliding coupling 25 which may alternatively be engaged with a fixed member to hold the spindle stationary when required. A wheel 26 on the spindle sleeve, which drives the milling spindle through a wheel 27 also engages a wheel 28 on a countershaft 29 which through bevel and spur gearing drives the leading screw 37 of the lathe. The countershaft 29 drives the drilling spindle by the bevel gearing shown in Fig. 1, while further gearing from the countershaft, comprising gears 31, 32, shaft 33, worm gearing 34, shaft 23, and the spur and bevel gearing shown in Fig. 4, operates the screw 24 of the table 4 to impart the slow feed for milling operations. The reciprocation of the table 4 for planing is obtained by reversing belt gearing from a pulley 22' on the mainshaft, which drives pulleys 22 connected by spur gears to the shaft 23, the planing and milling drives to the table being selectively obtained by means of a sliding clutch 35. An alternative drive 36 from the shaft 33 is provided for operating the lead screw.

Title: Improved manufacture of amine resins: the application thereof as base exchange bodies or the like
IPC: B01J39/18
Filed: 1937-01-20
Abstract: Resinous condensation products useful as adsorbing agents or base exchange bodies are prepared by condensing an aliphatic polyamine or polyimine built up with the molecular grouping <FORM:0489173/IV/1> (in which m is 2 or 3) with a polyhalogen derivative of a hydrocarbon or an aldehyde or a mixture thereof to produce a resinous gel, and hardening the gel with retention of its structure by cautious drying. The polyhalogen derivative may also be a hydrocarbon in which the carbon chain is interrupted by another atom such as a halogen atom product of an alkylamine or ether.  Suitable polyhalogen derivatives include methylene chloride, 1 : 2-dichloroethane, 1 : 2- or 1 : 3-dichloropropane, the corresponing bromides or iodides, b  : b 1-dichlorodiethylamine, 1 : 3 - dimethyl - 4 : 6 - di - (chloromethyl)-benzene.  Polyamines or imines, which may be prepared in situ from the monomeric bodies, include polyethyleneimine, polyethylenediamine and the corresponding propylene derivatives.  The condensation may be effected in the presence of aromatic amines, phenols, or preliminary condensates derived therefrom.  In examples: (1) polyethyleneimine is condensed with 1 : 2-dichloroethane or firstly with 1 : 2-dichloroethane and subsequently with formaldehyde; (3) polyethylenediamine is condensed with 1 : 2-dichloroethane; (4) aqueous ethyleneimine is condensed with b  : b 1-dichlorodiethylamine and subsequently with formaldehyde; (5) aqueous ethylene imine containing ethyl alcohol is condensed with methylene chloride and then with formaldehyde; (6) 1 : 3-diaminobenzene or aniline is condensed with formaldehyde in the presence of aqueous hydrochloric acid, mixed with (a) polyethylene imine or diamine, or ethylene diamine, and then reacted with further formaldehyde or (b) a reaction product of polyethylene imine and 1 : 2-dichloroethane; (9) polyethylene imine is condensed with 41 : 61 - dichloro - 1 : 3 : 4 : 6-tetramethylbenzene in solution in xylene.  The products, which are strongly basic, may be used in the purification of liquids or gases. In examples: (14) water freed from alkali ions by filtration through a cation exchange body is filtered through a resin derived from polyethylene imine and 1 : 2-dichloroethane or from 1 : 3-dimainobenzene, polyethylene imine and formaldehyde to remove chlorine and sulphate ions, the resin being subsequently regenerated by treatment with caustic soda; (15) copper is removed from an ammoniacal copper solution by filtration through a resin derived from ethylene imine and methylene chloride.  A sample has been furnished under Sect. 2 (5) of a resin prepared by condensing m-phenylenediamine with formaldehyde in the presence of aqueous hydrochloric acid, mixing the product with polypropylene 1 : 3-imine and condensing the product with formaldehyde.
