Title: Improvements in or relating to polyamine resins
IPC: B01J41/14
Filed: 1957-02-28
Abstract: Ion-exchange resins are prepared by (a) reacting (i) a di (halo-methyl)-alkylated-benzene with (ii) a polyalkylene-polyamine containing at least two primary amino groups and at least one secondary amino group, there being a chain of 2, 3 or 4 carbon atoms between each two adjacent amino nitrogen atoms, and (b) alkylating the reaction product to form a quaternary ammonium salt.  Component (i) may be dichloromethylxylene or -mesitylene, and the halogen may be Cl, Br or I, and the alkyl group ethyl or methyl.  Component (ii) may be triethylene tetramine or tetraethylene pentamine, and the alkylene groups may be ethylene, propylene or butylene.  Stage (a) is preferably carried out in the presence of a hydrogen halide acceptor, e.g. Na OH, and stage (b) by condensing the product of stage (a) with an aldehyde and then quaternizing with an alkyl halide.  The resultant quaternary salt may be used as an ion exchange resin or it may be converted into a base by treatment with caustic, in which case it will absorb strong acids from media such as water.  In the Example a benzene solution of tetraethylene pentamine, 4,5-dichloromethyl-oxylene, methanol and diatomaceous earth is refluxed, with intermediate additions of further dichloromethyl-xylene and excess aqueous NaOH, washed, ground and dried.  The product which itself has ion-exchange properties is then reacted with aqueous formaldehyde containing NaOH, and with a toluene solution of methyl iodide ; the solid product is filtered off, heated with aqueous NaOH, washed and dried.

Title: Improvements in or relating to the manufacture of artificial textile materials and the like
IPC: D01D5/08
Filed: 1940-04-17
Abstract: 541,238. Artificial filaments. DREYFUS, H. April 17, 1940, No. 6913. [Class 2 (ii)] Artificial filaments are produced by extruding a fluid synthetic thermoplastic fibre-forming substance into an inert gas or vapour and cooling it in that medium to a temperature at which air has no damaging effect. The material is then passed into air and its setting is completed. A form of apparatus for spinning a molten polymer is shown in Fig. 1. A narrow tube 3 is surrounded by an electric heating element 4 and mounted in the upper end of a cylindrical casing 5 ; it feeds molten material to the spinning jet 7, which is closely encircled by a heating element 8. The filament 9 passes down to a guide bar 10 and through a small opening 11 to a feed roller 12. An inert gas or vapour is supplied to the upper part of the apparatus through a pipe 13 and holes in the ring 15. This is withdrawn through the ring 17 and pipe 18, so that the top part of the casing remains full of inert gas while the bottom part contains air admitted through the gauze 20. Some air passes out through the pipe 18, and a diaphragm 21 between the ring 17 and the casing wall prevents the passage of air or vapour from one part of the casing to the other. Heating elements 22 may be provided on the inner surface of the casing. A line of jets may be employed in the casing. The inert vapour or gas may be diethyl ether, dioxane, ethyl chloride, carbon tetrachloride, nitrogen, carbon dioxide or hydrogen, and it may be heated before introduction into the apparatus.

Abstract: 1,004,972. Surge diverters. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Feb. 19, 1964, No. 6942/64. Heading H2H. A spark-gap arrangement for a surge diverter comprises a stack of metal electrodes 2 spaced by ferromagnetic quenching plates 3, insulating rings 4 and ceramic pieces 10 which increase the capacitative control. T-shaped slots 16, 17 in each electrode 2 confine the arc current to a narrow path 2a between protuberances 14, 15, each of which is aligned with another protuberance on the adjacent electrode and with apertures 3a in the plates 3 converging to slots 18, the arrangement being such that the arc formed between members 14, 15 is driven towards the slots 18 and extinguished. Each arc chamber may be openended in the blowing direction by providing the insulating members 1, 4 with suitable openings (not shown). The slots 16, 17 are covered or filled with insulating material and their stems 16a, 17a may extend arcuately instead of radially from the portions 16b, 17b. Voltage control resistors may be provided. A modification to provide an increased leakage path between adjacent electrode plates is described, Fig. 3 (not shown). Other modifications envisaged are as follows:- (1) Slots 16b, 17b are omitted and slots 16a, 17a are extended towards each other. (2) The protuberances 14, 15 are oblong with their longitudinal axes passing through the electrode centre, the protuberance slope to the electrode surface being greater towards the centre than towards the edge (arc blow-out direction). (3) The quenching plates each comprise a ferromagnetic U-shaped portion flanking an aligned pair of protuberances, the plate being completed by a non- ferromagnetic portion, e.g. brass or press-board. Each such complementary portion may have a cavity accommodating a pre-ionization element and/or a control resistor. (4) A cylindrical control resistor may be located between a pair of electrodes by means of a leaf-spring attached to one electrode and abutment surfaces on the other. The resistor may be replaced by a ceramic disc which acts as a pre-ionizing element. Fig. 5 shows an electrode which is centrally stepped at 2c to produce parallel portions 2a, 2b having slots 16, 17 and oblong protuberances 14, 15. Fig. 4 shows a stack comprising two such electrodes spaced by generally U-shaped quenching plates 3 and insulating spacers 4 having hemispherical apertures so arranged that a wedge-shaped air gap 7 is formed between the spacer 4 and the step 2c to provide inherent pre-ionization of the gap between protuberances 14, 15. Spacers 4 and insulating rings 5, 6 have cut-outs and projections to prevent twisting of the stack during assembly, Figs. 7 and 8 (not shown).

Abstract: 1,062,246. Transistor switching circuits; inductive control systems. HARTMAN METAL FABRICATORS Inc. Feb. 18, 1965 [March 4, 1964], No. 7040/65. Headings H3T and H4U. [Also in Divisions G3 and H2] In an arrangement for positioning a lift or machine tool carriage its driving motor is controlled in speed and direction according to the magnitude and phase of a signal induced in a pick-up (20, Fig. 1, not shown) on the carriage by A.C. in conductors (216, 217) (which may be printed) on a stationary member, the conductors being crossed at stopping points (214). The signal is compared (at 38) with that from a tacho-generator and the difference is amplified, and rectified and appears (at point 50) as a D.C. signal, the polarity of which depends upon the disposition of the conductors (216, 217) under the pick-up coil. Control circuits are provided such that this voltage effects the switching of three-phase A.C. to the drive motor and also controls an electromechanical brake (27). When the pick-up is intermediate the crossing points the motor is continuously connected for rotation in the appropriate direction; when the converging portion is reached the decreasing signal causes the motor to be disconnected intermittently until finally the brake is applied. Overrun results in reversal. The required stopping point is selected by a counting mechanism ; until the desired point is approached control is by a separate, undisclosed, system. Control circuits.-The speed signal voltage (at 50) is applied to two tunnel diodes (58, 62) one or the other of which conducts and operates switching transistors (64, 70, 75 or 78, 84) when the signal potential (at 50) is above a predetermined value. The resulting potential (on line 77 or 82) is applied to further transistors (109, 111, 113 or 110, 112, 114) which then conduct during the positive half-cycles of the threephase supply (at 100, 101, 102) to which their collectors are connected through saturable reactors. This generates triggering pulses for thyristors (157... 161) which thus shortcircuit the secondaries of transformers (162 . . . 166) so that their primaries present a low impedance in the lines from the supply (100, 101, 103) to the motor in a phase sequence appropriate to the required direction of travel.
