Abstract: 1358813 Examining bank-notes M MARTELLI and M MARTELLI 13 Oct 1972 [15 Oct 1971] 47308/72 Heading G1A In an optical analyzer suitable for checking bank-notes 7a light source 1 and two photosensitive members 5 and 3 are positioned so as to provide output signals representing the transmissivity and reflectivity of a predetermined area of the bank-note 7, the output signals being electronically compared with reference ranges for the transparency and reflectivity of genuine bank-notes to determine the validity of the note. The source 1 is rotatable about its own axis by holder 9 so as to orientate the image of the filament on the bank-note in any desired manner. A plurality of analyzers for simultaneous measurement of several points may be employed. The position of the analyzer may be adjustable Figs. 6, 7, 8 and 9, (not shown), in that the whole analyzer may be incorporated in a support head having a pair of stop pins which can engage a selected one of a plurality of pairs of holes in a base member. The optical analyzer may be included in a detection system for a reading machine that examines, the watermark present in the bank-note (i. e. its transmissivity at that point), the reflection from a printed surface of the bank-note at the different areas, the wire passing through the interior of the bank-note, the type of paper used, the bank-note thickness and the length of the bank-note. An associated control circuit Figs. 10 and 11, (not shown) will then only provide a signal for accepting the banknote and dispensing the merchandise when all the above criteria are satisfactory. In the Fig. 3 embodiment a bank-note is fed via an inlet 29 along a guide 31 thereby triggering an ingress switch 11 (a micro-switch or photoelectric relay) and energizing rollers 17A to feed the bank-note along the guide 31 into the analyzer 15 where it scrutinizes several selected discrete points of the bank-note and provides signals which are processed to determine the bank-notes validity and to activate an electromagnetic switch 33 which will direct the banknote along path 37 (dotted lines) or along path 35, depending upon whether or not the bank-note has been accepted or rejected. The bank-note is stretched while it is being scrutinized because rollers 17B drives the bank-note at greater speed than the first pair. While the bank-note is being examined in the analyzer its presence there, that is, its leading edge, is detected by a reset switch 19 which causes the rollers 41 to be locked preventing further notes from being placed in the machine, while a note is in the analyzer.

Abstract: 1,247,178. Repertory diallers. TELEMASTER G.m.b.H. 5 Oct., 1968, No. 47339/68. Heading H4K. A repertory dialler has a plurality of discs 3 having cams 14 around their periphery which when read by a follower 20, during one revolution of the discs, provide impulses corresponding to a complete telephone number. In the present dialler, provision is made for resetting the mechanism by engaging a high-speed drive for the discs and at the same time inhibiting the production of pulses. The discs 3 are mounted on shaft 4 and driven through a ratchet type one-way drive by worm 8 which is driven by motor 5. Also mounted on shaft 4 is a gear which co-operates with pulley wheel 39 which is belt driven by motor 5 to give a high-speed drive to the discs. A releasable coupling is included within pulley 39 and is operated by downward movement of lever 46 when reset button 76 is pressed. Associated with each cam 9 is a selector bar 2 which has a follower 20 which rests on the disc periphery when selector key 1 is pressed and the whole bar 2 moves in the direction of arrow 16. A pawl arrangement 15, common to all discs, is actuated by nose 19 of bar 2 when it contacts a raised cam 14 and rotates lever 22 about pivot 23 so that cam 32 closes contacts nsa and rod 26 unlocks coupling 27 to drive wheel 29 and operate contacts nsi to give the required number of impulses. When bar 2 moves back it strikes bar 112 which moves stop 109 away from pin 107 so that wheel 93 can rotate and cam follower 100 can operate motor switch 89. Electromagnet 81 is also energized to raise finger 85 which together with finger 117 locks bar 2 in position. After an initial digit group has been sent, the follower 20 enters a deep notch in the disc which causes a subsidiary switch to operate and stop the motor. If the call is to proceed an auxiliary start button (135) is pressed and the motor re-starts to continue sending impulses. If the line is busy, reset button 76 is pressed which operates through the linkage shown in Fig. 5 to open the contact a 1  in the circuit of electromagnet 81 and impulsing contacts nsi so that impulses are not sent. Additionally the high-speed drive is engaged by lever 46 engaging the coupling in pulley 39 and the discs are driven until cam 61 engages lever 46 to disengage the pulley 39 and restore the drive through worm 8 so that all the linkage is reset and the motor stops when follower 100 engages notch 98 in wheels 92, 93.
