Title: The electrothermic production of carbon disulphide by fluidized bed techniques
IPC: B01J8/42
Filed: 1957-02-25
Abstract: <PICT:0855245/III/1> <PICT:0855245/III/2> Carbon disulphide is produced by passing a gas comprising hydrogen sulphide up through a finely divided bed of carbon or silicon carbide particles which are thus formed into a fluidised bed and is heated by passing current therethrough to maintain a temperature e.g. 1200 DEG C.-1600 DEG C. whereby carbon disulphide is formed and is recovered from the outgoing gases.  The carbon particles are preferably petroleum coke from a fluidised bed petroleum coking process and are preferably calcined or are of metallurgical coke or stoker coke.  The particles pass a 14 mesh U.S. standard sieve. The contact time of the gas with the bed is preferably 2 seconds.  A.C. or D.C. is used and open arcs are avoided.  Several carbon electrodes may be arranged in the bed to give even heating, and three electrodes may be used with a three phase supply.  Thus in Fig. 2, hydrogen sulphide entering at 12 is distributed evenly by passage through coarse inert particles 14 in a chamber 11, the wall of which forms one electrode.  A central axial graphite rod 15 forms the other electrode, the carbon disulphide passing off at 17. Alternatively, two graphite electrodes may be inserted from above into the bed.  In Fig. 3, a reactor tube 18 of glass or ceramic is used, the gas entering at 20 being evenly distributed by a gas disperser 21.  Electrodes 26 inserted from above carry heat radiation shields 29, 30.  A thermocouple is inserted in a well 28.  The carbon disulphide produced passes to an outlet 23.  If sulphur is present in the coke used, it is also formed into carbon disulphide.  After an initial high gas entry speed to fluidise the bed, the rate of gas entry is lowered.

A beam 2 of a rack frame, or a cantilevered bracket, has at one or both ends a flange 8 with pressed out hooks 9 selectively engaged in vertically spaced holes 5 in an upright 1 and the engagement is maintained by a spring steel locking strip 12 carried by the flange 8 so that it may be rocked transversely and flexed away from the upright 1, the strip 12 having a wing portion 13 engageable through a hole 11 in the flange 8 in the open part of a hole 5 above an engaged hook 9. The upper part of the strip 12 may be pivotally riveted to the flange 8 or, as shown, may have a stamped out tongue 14 which hooks over the lower edge 10a of a hole 10 created by pressing out a hook 9. Dimples 21 engage the sides of the hole 10 to centre the strip 12. A finger piece 20 of the strip 12 locates in a flange hole 10 in the locked condition.

Abstract: 1,017,122. Moulding and filling closed containers. H. PECHTHOLD. Oct. 23, 1962 [Oct. 25, 1961], No. 40009/62. Heading B5A. A container is blow-moulded and filled with a flowable material simultaneously by introducing the flowable material, under pressure, into a hollow body of thermoplastic material and allowing the enclosed air to escape against a back pressure so that the hollow body is expanded to the shape of a mould and is then closed. As described, a tube 6 of thermoplastic material (Fig. 1) is extruded about a core 1 and passes between mould havles 24, 25 which are closed about the tube. The flowable material is then introduced through bore 7 while the air inside the tube escapes along vent 22 against a back pressure caused by a throttle valve 21. The flowable material is fed under pressure from a pressure vessel 10 which has a source of pressure 13 (e.g. compressed air), the pressure vessel 10 being supplied from a reservoir 15 by a pump 14. When the container is fully expanded and is filled, the excess flowable material may return to the reservoir via the vent 22 and conduit 20. The tube 6 is then severed and mould parts 28 are moved away (Fig. 1d) to allow the neck to be sealed by jaws 31. Alternatively, the mould parts 28 may produce a screw-thread on the neck of the container which can then be closed by a screw cap (not shown). In a second embodiment the flowable material is introduced at the bottom of the container as shown in Fig. 2a. In a further embodiment, the tube may be closed at both ends (Fig. 4a) and the inlet and outlet vents are formed by hollow needles 35, 36. In each of these embodiments the outlet vent 22 may be connected to a source of compressed air (not shown) to provide the back pressure and also to increase the pressure of the air in tube 6 prior to the introduction of the flowable material.

In the method of extruding beryllium tubes according to Specification 884,410, the envelope comprises a tubular liner 5 surrounding the beryllium billet 3 and an outer casing 6 formed from a plurality of longitudinally divided parts secured together as by welding but detachable from the liner. The beryllium billet 3 has a core 4 which may be of mild steel or a manganesenickel steel having a higher expansion coefficient than beryllium to facilitate its subsequent removal. The liner 5 may be of steel and end pieces 7 are welded between the core and liner. Outer casing 6 is formed by four segmented parts, Fig. 2 (not shown), welded together at their ends and along their longitudinal dividing lines. The steel is first oxidized or has an oxalate coating and is then coated with lime to prevent the components from welding together during extrusion which is performed at 900- 1100‹ C. After extrusion the welds of the casing are removed by machining or pickling, the ends are cut off and the casing parts removed. Core 4 and liner 5 are then removed by pickling in nitric acid. The core 4 may be solid or may comprise a tubular core and a solid insert of a different material.
