Abstract: 1436712 Ticket feeding and printing LONDON TRANSPORT EXECUTIVE 27 March 1974- [16 Feb 1973] 7813/73 Heading B6C [Also in Divisions B8 and G4] In ticket apparatus, the orientation of an inserted ticket is sensed and the ticket is then fed between a pair of printing heads, one of which is energized, depending upon the sensed orientation, to print data on a particular ticket surface, e.g. the date and/or time. In the embodiment shown, a ticket presented at A, Fig. 2, is rejected at G if it fails a validity test carried out at F on a magnetically-encoded ferric oxide side of the ticket. If it passes the validity test, the ticket is diverted at H and fed by conveyers 1 past sensors 2 and 3. On sensing the ticket, sensor 2 emits signal 2a, Fig. 1, which passes to one input of each of two AND gates 2b, 3b. The ticket is non-light reflective on the ferric oxide side and lightreflective on the other side, which bears some pre-printed matter and is to receive more. Sensor 3 can distinguish between the two sides of the ticket and its output 3a is applied to a flip-flop 3c to enable either AND 2b or AND 3b according to the ticket orientation. The enabled AND sets an associated flip-flop 2d or 3d to energize a corresponding top or bottom magnetic particle clutch 4a or 4b, which includes formations 4B to impart serrations to the ticket. The setting of flip-flop 2d or 3d also sets a flip-flop 2e or 3e, which remains set when 2d or 3d is reset, which it is by a unit 7 to discontinue energization of the operative clutch 4a or 5a. A detent 6 accurately positions the clutch in its home position. A signal is sent to one input of each of two AND gates 2f, 3f by a device 9 when the latter senses the trailing edge of the ticket. The set flip-flop 2e or 3e signals the other input of the associated AND 2f or 3f to enable same and thus energize either a top or bottom date stamp operating solenoid 11a or 11b. Flip-flop 2e or 3e is reset by a detector 13 when the latter senses the trailing edges of a ticket.
