Title: Improvements in process and apparatus for purifying zinc ore
IPC: C22B19/02
Filed: 1930-05-27
Abstract: <PICT:0358039/III/1> <PICT:0358039/III/2> Zinc ore is crushed and wetted and a portion thereof heated to vaporize the volatile contents, e.g. lead and cadmium, which are condensed in another portion of the ore to be separated from the remainder.  The wetted crushed ore is fed by a hopper 45 into contiguous sintering pans 12 on an endless track 19.  The ore then passes under a sintering hood 48 containing burners 49 which drive the more volatile lead and cadmium as sulphides or sulphates into the lower portion of the ore, the zinc remaining unvaporized.  A vacuum chamber 38 beneath the pans 12 sucks down the vapours to condense them in the lower part of the material, which passes to a scraping plate 51 removing in co-operation with an endless conveyer 50 the top layer of ore.  The lower layer of ore is discharged on to a screen 59 over a hopper 60, and the coarse material is returned to form a bottom layer in the sintering of fresh ore.  The fine material is mixed with carbon, wetted and fed to a second conveyer where the sintering is repeated. The pans have lateral walls and rollers, are open at their ends, and have perforated bottoms.  The first burners 49 have an oxidizing flame, the later burners a reducing flame.  The zinc ore is first roasted to remove most of the sulphur.

Title: Apparatus for loading containers with packets
IPC: B65B57/06
Filed: 1975-05-16
Abstract: 1491475 Automatically loading containers RANPAC Ltd 16 May 1975 [16 April 1974] 16504/74 Heading B8C Filled packets are tested for sealing and are then weighed and conveyed to a shoot where they are queued and counted and allowed to drop into a vibrating carton. In Fig. 1 the packets are advanced by a conveyer 2 beneath a depressor 4 which moves downwardly on to each packet to test its resistance and therefore its seal, a badly sealed packet depressing sufficiently to allow pulley 43 to operate a reject switch. An arm 44 is also pivoted by each packet and operates a switch 46 to pass the packet on to a check weigher 5 or operate an alarm or air blast reject means. After weighing, an elevator 6 carries the packets on fingers 9 to a shoot 11 containing arresting means 13 having an air cylinder operated flap 14 controlled by a counter to allow a counted number of packets to fall into carton 36 held by air operated clamps 30, 31 on a vibrating platform 21. The empty cartons are advanced on a conveyer 18 to a biased stop bar 19 and moved by an air operated kicker arm 20 to the platform 21, the bar 19 detecting the presence of a new carton and actuating a switch which controls the number of packets discharged in relation to the counter signal. In a modification the arm 20 and its cylinder 24 is supported from the shoot 11 allowing closure of the flap 14 to be synchronized or mechanically linked with the movement of the arm. In Fig. 2 the kicker arm 49 and carton wheel stops 59 are air operated and cartons are moved along the conveyer 53 and then on to a sloping sided vibrator 54 where each carton is loaded, shaken, and then pushed on to take off conveyer 55. A photo-electric detector (not shown) receives a beam 60 extending across the shoot and signals to a display counter 61 which produces a signal when it reaches a predetermined count to re-set itself and energize a first delay device 64. This delay allows the last packet to clear the flap 65 and the output from 64 is fed to operate an air cylinder 57 which raises the stops 59 to intercept a carton 53. A second delay device 67 delays 64 still further to allow any carton already over the stops to travel past. The output from 67 operates a cylinder 51 and arm 49 to move the carton on to platform 54 and the part 68 of the arm closes contacts 69 to open flap 65. The arm 49 is then returned by the signal produced through contacts 69 and this signal is sent via switch 70 to lower the stops 59. Actuation of 70 by a demand from another machine for more cartons and also being fed by the conveyer 53 causes stops 59 to lower and feed a carton to that machine. Arrangements are made so that filled cartons do not collide on the take off conveyer.

Title: Process of and apparatus for the degasification of fine-grained or pulverulent fuels or the like
IPC: C10B49/20
Filed: 1950-07-03
Abstract: 672,157. Distilling carbonaceous material. METALLGES. AKT.-GES. July 3, 1950 [Aug. 3, 1949], No. 16566/50. Class 55 (i). A process for the distillation of finelydivided fuel comprises passing the fuel admixed with a circulating heat carrier through a chamber in a closed charge, i.e. so that the relative positions of the charge particles remain unaltered, the heat carrier, after passage through the chamber, being elevated pneumatically for recirculation and, at the same time, being heated by combustion of the carbon contained therein. In the form shown, the apparatus consists of a cylindrical distillation chamber 1 connected at the top by a shaft 4 to the base of a separator chamber 3, a conveyer shaft 2 passing from the latter concentrically through shaft 4 to the base of chamber 1. Fuel, of grain size less than 1 mm., is continuously admitted from a hopper 5 to the annular space around shaft 2 and passes, with heat carrier material of grain size from 0.1 to 1.0 mm., and heated to 600- 1200‹ C., descending from chamber 3, into chamber 1, where distillation of the fuel occurs at 400-1000‹ C., the evolved gases passing off through outlet 9. The coke descends to the base of chamber 1 via a throttling damper 10 and passes laterally into the lower part of shaft 2, where it meets a stream of superheated air entering from line 11 and is thereby lifted up the shaft 2, combustion of part of the coke occurring and so heating the remainder which separates out from the hot gases in chamber 3. The hot gases discharge through outlet 13 to a steam boiler 14 to which secondary air is admitted through a line 15. Any excess of coke formed is removed through an overflow 16. If the reaction coke is unsuitable for use as a heat carrier, sand &c. is added to the ingoing fuel. The calorific value of the made gas may be regulated by admission of steam, with or without air or oxygen to the fuel bed through a line 20.
