Patent GB-215009-A (GB)
IPC: G01R22/02
Filed: 1924-04-25
Abstract: 215,009. Siemens - Schuckertwerke Ges. April 26, 1923, [Convention date]. Electrolytic meters with multi-stage indicators are provided with a measuring-tube for a higher stage having a scale unit volume smaller than the total volume of the measuring-tube of the next lower stage, by causing a portion only of the quantity of the measuring-substance transferred to be received in the next following measuring- tube. In the construction shown in Fig. 1, the anode vessel 1 has a U-shaped extension 3, the free leg 4 of which serves as the first measuring- tube and is provided with a scale 5. A cathode 6, consisting of a glass dish over which fine wire netting is stretched, is arranged at the lower end of the tube 3. The anode vessel 1 is continued upwardly as a narrower tube 7, to which is attached a second measuring-tube 8 with a scale 9. To the upper part of the measuring-tube 4 is attached a siphon having a short leg 10 and a long leg 11 discharging into the upper measuring-tube 8. Into the upper measuring-tube 8 is inserted a second siphon discharging into the anode vessel 1. Initially the lower measuring-tube 4 is completely fi.led with electrolyte, which stands at the level N-N in the anode vessel 1 and at a somewhat higher level in the siphon leg 11 owing to capillary attraction. Hydrogen liberated at the cathode 6 collects in the measuring-tube 4 and depresses the level of the electrolyte in the siphon leg 10. Siphon action starts when the leg 10 is full of gas, the electrolyte in the leg 11 being driven into the measuring-tube 8 and the gas escaping into the anode vessel 1, the lower tube 4 again filling with electrolyte. The scale unit volume of the upper tube 8 is made equal to the quantity of electrolyte discharged each time from the leg 11. In the modification shown in Fig. 2, the gas emptied by the siphon 10, 11 from the lower measuring tube 4 is conveyed in part to the measuring-tube 8 and in part to the anode vessel 1. A short tube 16 with a siphon 17 is arranged over the exit of the siphon leg 11, the siphon 17 delivering into the measuring-tube 8. Initially both measuring-tubes, the tube 16, and all the siphons are full of electrolyte. Gas collects in the lower measuring-tube 4 until the siphon 10, 11 operates. The discharged gas quickly fills the tube 16 and the excess escapes into the anode vessel 1 before the siphon 17 operates and transfers the gas from the tube 16 to the measuring- tube 8. After ten such operations the siphon 13, 14 empties the gas from the measuring-tube 8 to the anode chamber 1 and the cycle of operations recommences.

Title: Method and apparatus for the thermal degradation of solid hydrocarbonaceous material
IPC: C10B49/06
Filed: 1961-03-21
Abstract: A process for the continuous thermal degradation of solid hydrocarbonaceous material having distillable potentially volatile matter therein comprises feeding the material at a controlled rate to a distillation chamber, allowing the material to fall freely therein whilst contacting it with a countercurrent of preheated hydrogen gas preferably at 15-30 atmos. so as to distil out volatile matter, and passing the resulting mixture of hydrogen and volatile matter to a catalyser wherein the volatile matter is autogenously hydrogenated, preferably at 750-950 DEG  C., the devolatilized material (char) being removed from the base of the distillation chamber.  The mixture obtained from the catalyser may be fractionated, the heavy bottoms recycled to the distillation chamber, and the methane, or methane from another source, passed to an isolated cracking chamber wherein it is decomposed to carbon and hydrogen, which hydrogen is passed to the distillation chamber, by contact with freely falling incandescent partially oxidized char derived from a combustion chamber fed by char from the distillation chamber, the char being heated therein by partial oxidation to a temperature just below that of ash fusion. Alternatively the thus heated char may be contacted with steam to produce water gas. The char from the methane cracking chamber may be similarly heated and contacted with steam to produce water gas. A series of alternate heating and water gas generating chambers may be arranged so that the char is finally reduced to ash. Alternatively char from the methane cracking chamber may be mixed with the heavy bottoms and briquettes to give synthetic coke.  A suitable apparatus comprises a distillation chamber having at least one gas outlet communicating with a catalyser chamber and at least one gas inlet each disposed between two vertically spaced gyratory shelves provided within the chamber, each shelf so co-operating with the side wall of the chamber or with structure attached to the side wall as to prevent the direct descent of solid material past the shelf, whereby in operation solids descending on to each shelf can accumulate and be temporarily retained in heaving motion thereon and be fed in an annular cascade from the periphery thereof at a controlled rate. Fig. 1 shows in detail a suitable construction of such a chamber. <FORM:0977905/C4-C5/1>

Title: Article Stacker
IPC: B65G57/00
Filed: 1967-03-06
Abstract: 1,162,582. Stacking articles on pallets. TRIDAIR INDUSTRIES. 6 March, 1967 [7 March, 1966], No. 10512/67. Heading B8C. A layer of articles formed on a roller platform 22 (Fig. 3) is pushed from the platform on to a stripper plate 28 (Fig. 7) which is simultaneously moved from beneath the platform 22, and the stripper plate is subsequently retracted so that the articles are stripped from it to fall on a stack supported on a pallet carried by a support 3 which is lowered in steps controlled, in the form shown, by a pendant plate 49. The pallet is previously delivered to the support 3 from a magazine: in the construction illustrated the magazine (106) (Fig. 4, not shown) delivers pallets singly to a roller table 5 (Fig. 3) raised and lowered in synchronism with the support 3, through a smaller stroke, so that the rollers 100, 71 may be driven simultaneously, when both supports are lowered, to discharge a loaded pallet and to replace it by an empty pallet. A stop 92 is gravity biased so that it will stop an empty pallet, even when the rollers 71 are driven, but will permit a loaded pallet to pass under these conditions. The articles to be stacked are delivered by an endless belt (6) (Fig. 2, not shown) to a roller table 13 where an operator marshals them and then pushes them on to the roller table 20 by means of a pusher 14. The articles are subsequently pushed from the roller 22, on operation of a switch by the operator, by pushers 36 which automatically rise to the position illustrated when they have cleared a transverse bar 40 (Fig. 7). Limit switches determining the sequence of operation may be overridden by the operator when he wishes a partially loaded pallet to be delivered. A tension-sensing device in the drive chain raising and lowering the pallet support 3 stops the lowering if the support jams.
