Abstract: 1449311 Copying by scanning J H LEMELSON 11 Jan 1974 01347/74 Heading H4F Signals derived from documents viewed by a television camera 63 are recorded, by recording head 48, on selected tracks of a magnetic record card R, Fig. 1, the signals from each document being recorded on a separate track; the signals recorded on a subsequently selected track are then read-out, by read-out head 47, and displayed on a cathode-ray tube 61. When a card is correctly inserted into the apparatus it engages a limit switch LS1 (also Fig. 2, not shown) which energises a solenoid 40 to extend shaft 41 into engagement with the card to retain it in position, and also energises a solenoid 51 to advance a magnetic pick-up head 50 into engagement with card R, the head 50 being located to scan a lateral track TX, Fig. 1 on the card, which has recorded thereon a plurality of marker signals C 1 -C N , one per record track. A counter 55 is preset, e.g. by a dial switch 54, to a selected track number, and the head 50 is moved, by a motor 30, transversely relative to the card R to scan track TX, each reproduced signal counting down counter 55. When counter 55 reaches zero it stops motor 30, retracts pick-up head 50 and extends read-out, recording, and erase heads 47, 48, 49 which are carried by a carriage (29, Fig. 2, not shown) which also carries pick-up head 50 and is driven by motor 30; the heads 47-49 are then correctly positioned for recording or playback, as determined by the setting of a switch 67, on the selected track. The zero output of counter 55 also energises a motor 25 to drive the carriage (29) parallel to the selected record track so that the desired signals are recorded or played-back. At the completion of this scanning a limit switch LS2 is operated which causes the heads 47-49 to retract and the motors 25 and 30 to return the carriage to its home position, completion of this operating a limit switch LS3 to stop motors 25 and 30. The record cards may be mechanically driven into the correct position, operation of limit switch LS2 causing the respective card to be ejected. The cards may be positioned on a flat platform or on a cylindrical surface.

As shown, a petroleum residuum is coked in the coker 101, and the resulting coke is removed by line 107 and transferred to the reactor 110 by steam introduced at 108. Air or oxygen may be injected at 109 to control the temperature. The coke is carried upwards through the zone 111 and heated by hot gases from the lower zone 112. It is disengaged from the gas by baffles 114 and cyclones 115, and part of it, controlled by a slide valve 119, passes into the gasifying zone 112. Here it is gasified by contact with air or oxygen from line 123 and steam from line 124. The resulting hot gas passes up through the zone 111, where it is cooled, and out through the cyclones 115. Line 120 controls the level of the fluidized bed in zone 112, by taking off any excess coke for recirculation. Another part of the hot coke in the zone 113 is taken off by the line 117, where steam is injected from line 118 to convey it back to the coker, where it supplies the heat needed for coking.
