Filed: 1957-07-18
Abstract: <PICT:0877610/III/1> <PICT:0877610/III/2> Apparatus suitable for the continuous production of melamine by the process of Specification 877,609 [Group IV(b)] and described with reference to that process comprises a reactor 1 provided with a stirring shaft, a tube 2 serving as a suspension washing device in which the precipitated melamine settles down, a sediment container 3 into which the melamine is led and displaces liquid ammonia upwardly through tube 2 to the reactor, a cooling device 20 for liquefying ammonia evaporated in the reactor, a manometric tube 23, a cooler 24, and a valve or sluice 21 initially containing dicyandiamide-ammonia stock solution, which is displaced by the liquid ammonia through heater 22 and mixing device 25 to the reactor.  Other features which may be added to make the complete apparatus illustrated are a melamine valve 4 initially containing liquid ammonia, a pump 5 which passes this ammonia to the sediment container 3 and so displaces the melamine crystal mash from 3 to 4 via duct 6; a reservoir 7 containing liquid ammonia which is used to displace the melamine crystal mash from 4 into suspension dryer 8 in which hot ammonia gas is circulated by blower-heater 9, and a cyclone 10 for separating the melamine; a dust filter 11 through which the ammonia is passed to gasometer 12, a compressor 13 for re-liquefying the ammonia, a fractionating column 14, and coolers 15 and 16, whence the liquid ammonia returns to reservoir 7, and a compression washing device 17 for washing residual gas from cooler 16 with water; a screw conveyer 35 for supply of dicyandiamide, which passes into a container 36 containing a saturated dicyandiamideammonia solution, a suspension washing device 38 for the dicyandiamide leaving 36 and an overflow arrangement 43 by way of which the impure dicyandiamide solution passes to heated paddle screw conveyer 44 for recovery of dicyandiamide and ammonia, the latter passing to gasometer 12 by way of dust filter 45; a dissolving vessel 39 into which the washed dicyandiamide passes, a storage container 31 for the dicyandiamide mash, ducts 41 and 42 by which liquid ammonia is displaced from 31 into dissolving vessel 39 and storage tank 32 for dicyandiamide-containing liquid ammonia, a preliminary dicyandiamide valve 27 into which the dicyandiamide mash is displaced by the dicyandiamide-containing liquid ammonia from 32, and a pressure container 29 into which passes the dicyandiamide-containing ammonia initially in 27; ammonia passes from container 29 to cooler 16 and is re-liquefied, and the residual dicyandiamide-containing ammonia passes to gas separator 34 where it is expanded and passed to storage tank 32, ammonia gas passing to gasometer 12; the dicyandiamide mash is passed into valve 21 from valve 27 by means of displacement with liquid ammonia which is pumped from 21 to 27 by pump 26.

Abstract: 1,187,363. Welding by fusion; corrugating wire. AIR REDUCTION CO. Inc. 27 March, 1968 [27 March, 1967], No. 14715/68. Headings B3E and B3R. In seam welding by deposition of layers of welding metal in a narrow gap between workpieces, a consumable electrode of serpentine form is used so that the arc oscillates from wall to wall of the gap as it progresses along the gap. The electrode may be pre-shaped prior to reeling, or a reel 100 of straight wire may be fed through guide rolls 106 on oscillating axes and guide rolls 108 on stationary axes by knurled feed rolls 112. The rolls 106 are supported by a pivoted bracket 122 oscillated by a crank 138 driven by a variable speed motor 130 to bend the wire beyond its elastic limit. Alternatively the bracket 122 may be reciprocated linearly by a double acting pneumatic ram. The sinuous wire, e.g. aluminium or steel, is fed by the rolls 112 through a slot 25 in a contact tube 118 having an insulating coating. During welding the slot 25 is positioned across the gap and the contact tube 28 is located within the gap by a rack 34 and pinions 36. In gas shielded arc welding apparatus a gas nozzle 38 having mesh layers 46 across its outlet to produce laminar gas flow is slidably mounted on the contact tube 28 and is positioned adjacent the work surface by a rack 40 and pinion 42. In submerged arc welding the contact tube is preceded by a flux discharge nozzle located within the gap. A bare, cored or coated electrode may be used. Pulsed arc or welding with spray, drop or dip transfer may be used. The arc oscillates at 25-100 ~/see.

[Class 16.] A manifolding carbon-pack comprises a series of carbon sheets each having a reinforcing-strip of material extending across one end, the strips having projecting portions extending clear of the carbon sheets and being secured to a backing-sheet arranged below the carbon sheets. The backing-sheet 1, preferably of strong paper, is wider than the record sheets and the carbon sheets 2, to each of which is fastened a cross-strip 3, the ends thereof being secured to the marginal edges 5 of the sheet 1 so that the central portions are left unsecured for a width slightly greater than that of the record sheets, in order that these can be suitably threaded through the pack. The cross-strips 3 may be attached to the carbon sheets at an edge which is free of carbon material by doubling a strip round an edge and gumming it thereto. A reinforcing-cord may be inserted into the folded edge of the strip 3 to form a more-rounded edge and when no edge of the carbon sheet is free from copying-material holes may be punched therein at intervals and the folded strip 3 when gummed to the edge then interlocks therewith through these apertures. The strips 3 are mounted on the sheet 1 in slightly offset relationship. When the top sheet to be typed is a separate letter sheet, the bottom edge 12 of the backing-sheet 1 forms with the adjacent carbon sheet or pocket into which the edge of the letter sheet may be inserted, and in order to provide a stop for the inserted sheet, the first carbon sheet may be attached throughout its width to the backing-sheet 1.

The contacts at the busbar end may be in the form of notches in the busbar itself, cells in the sections at this end being dispensed with. The contacts at the other end may be mounted beneath the sections on an insulating bar so that in this form the sections form a slotted protective covering or shield for the fixed contacts and do not themselves carry contacts.
