In an articulated-plate conveyer having overlapping troughed plates 8 connected to a pair of endless roundlink chains 12, each plate extending over several chain pitches, the rear end of the bottom of each plate is suspended below the forward end of an adjacent plate by means of projecting stubs 3 on the former engaging in slots 7 formed in the side walls 8 of the latter, to allow for wear of the chains and relative pivotal movement between the plates. The floor of the rear end of each plate is bent to an S-shape in cross-section, forming an upwardly facing recess 2 in which the stubs are welded and a downwardlyfacing recess 4 to accommodate the forward end 5 of the following plate during flexing. The slots 7 may be extended by strips 9, 10 should wear in the chains become excessive, to prolong further the need for chain replacement. The plates are secured to the chains by brackets 11 on the outer ends of the stubs. In a modification, Fig. 3, a member 14 is welded within the rear end of a troughed plate to provide each stub 3. On the end of each stub 3 is a bracket 18 which is forked to receive a clamping member 19 for a horizontal link 20 of the chain, the member 19 being held in place by a pin 21. The forked end of member 19 is rounded to allow pivotal movement of link 20 about pin 21.

Title: An improved method for cleaning spinnerets and like objects provided with small orifices by means of liquids
IPC: D01D4/04
Filed: 1958-01-28
Abstract: <PICT:0824538/IV (a)/1> Spinnerets and like objects having small orifices are cleaned by directing a converging bundle of ultrasonic vibrations upwardly through a body of cleaning liquid and bringing the object to be cleaned into the bundle with its face directed transversely to the axis of the bundle and on a point in or near the focus of the bundle, the liquid surface being adjusted at the level of the focus of the bundle and the object being brought into the boundary layer of the liquid, so that the column of liquid spouting upwards induced by the vibrations strikes the underside of the object and is ejected through the orifices of the object in the form of a miniature fountain of jets which travel freely through the air above the surface of the liquid and fall back into the latter and on to the upper surface of the object.  As shown, a spinneret 26 to be cleaned is held face upwards in a beaker 21 by means of a holder 27 with its face transversely disposed with respect to the axis of a bundle of ultrasonic vibrations generated in a cleaning liquid, such as a volatile organic solvent, contained in the beaker 21 and with its face on a level a little higher than the undisturbed liquid surface around the central portion of the liquid spouting upwards.  The ultrasonic vibrations are generated in a known manner by a piezo-electric plate of quartz 1, the parallel planar surfaces of which are metallized and the lower metallized surface of which is in electrical communication with a high-frequency generator via screw terminal 13, metal conductor 12, metal contact plate 7 and metallic gauze 9.  The space between a metal container 4 and a glass vessel 14 is filled with transformer oil, and the container 4 with a vibration transfer liquid such as water.  The cylindrical bundle of ultrasonic vibrations generated by the quartz plate 1 is converted into a converging bundle by the concave lens-shaped portion 24 of the phenol-formaldehyde resin bottom 23 of the beaker 21, the vertical wall of which is of aluminium.  Very small liquid columns form at the spinneret orifices, and from the appearance of these columns it is possible to judge whether the orifices are fully or only partially cleaned.  The concave lens 23 may consists of polystyrene or polymethyl methacrylate.  The concave lens may be omitted and the upper surface of the quartz plate may be concave in order to cause the bundle of ultrasonic vibrations to converge.

Title: Production of gaseous hydrogen chloride from aqueous hydrochloric acid by distillation
IPC: C01B7/01
Filed: 1956-02-02
Abstract: In a process for the production of dry hydrogen chloride from aqueous hydrochloric acid of 30-40 per cent strength by distillation under a pressure of 1 to 2 atm. (gauge) in a packed column 22 made of graphite, the acid to be distilled is heated in an evaporator 19 to 115-120 DEG  C. under the operating pressure, and the <PICT:0788421/III/1> resulting mixture of gas and liquid is introduced tangentially into a packing-free space 21 in the middle section of the column; the gas leaving the head of the column is passed to a condenser 25 where moisture condenses as highly-concentrated hydrochloric acid, and the dry gas is collected in container 29.  The highly-concentrated acid is withdrawn from separator 26, and is supplied to the top of the column as reflux; while the dilute acid reaching the base of the column is heated to about 120 DEG  C. in evaporator 23 to remove as much HCl gas as possible, and is then passed via heat-exchanger 18, cooler 34 and siphon 35 into container 5.  A current of gaseous hydrogen chloride, containing only about 0.02 per cent of moisture, is withdrawn as product from container 29 via conduit 30 and regulating-valve 31.  In order to free gaseous hydrogen chloride, obtained in organic synthesis, from inert gases and unreacted chlorine, the impure gas is introduced through conduit 1 into the lower part of absorber 2 consisting of graphite tubes cooled with water. Aqueous hydrochloric acid (20-24 per cent), from container 5, is introduced through conduit 3 into the top of the absorber.  Inert gases and chlorine are eliminated from the absorber through conduit 9; and strong hydrochloric acid (36-40 per cent) is collected in reservoir 8.  This strong acid is pumped through conduit 11 into overflow-vessel 13, from which the major part flows via conduit 15 and heat-exchanger 18 into evaporator 19. This evaporator and also heat-exchanger 18 are made of graphite material.  The feed acid is preheated to 70-80 DEG C., in heat-exchanger 18, by the hot acid withdrawn from evaporator 23 at the base of the column.  The height of siphon 35 can be adjusted by rubber-tube connections 36 so that the desired column pressure and a suitable level of liquid in evaporator 23 are maintained.
