Abstract: 1,268,083. Recording-apparatus. KIENZLE APPARATE G.m.b.H. Aug.12, 1969 [Oct. 8, 1968], No.40305/69. Heading G1J. In recording-apparatus with a stylus 6 guided inwardly and outwardly over a radial co-ordinate of a clock-driven disc chart 7 in synchronism with the chart drive and brought into contact with the chart 7 by a stylus actuating arrangement M to produce recordings in concentric tracks according to data to be recorded, the arrangment M is influenced (i) by one or more piece pulse transmitters s of one or more machines 21 to record single discrete strokes 33, 34 representing quantities and (ii) by one or more time transmitters r actuated by the machine(s) 21 and by a selected manual switch t 1  to is to record bands 30, 31 registering running times and 32 registering a reason for interruption of running. Radial inward and outward movement of the stylus 6 is produced by a motor 9 rotating a shaft 10 to drive a crank disc 12 which reciprocates a support 13 for the stylus 6 and its actuator M. The sources of data namely transmitters s, r and switches t 1  to t 6  are connected to the actuating arrangement M by the wiper 22 of a rotary switch 44, which wiper 22, being mounted on the shaft 10, is driven over contact segments k 1  to k 16  in synchronism with the stylus 6. As shown in the wiring diagram of Figure 4, the contacts k 1  to k 9 , k 15  and k 16  are associated with recording through the stylus actuator M and the contacts k 10  to k 14  with feeding piece pulse data from a preliminary store 38 to flip-flop circuits 41, 43 to determine the state L or O of each so that each revolution of wiper 22 has a feeding and a recording phase. For determining the conditions L, O of the circuits 41, 43, piece pulses from a switch s (which occur independently of the movement and actuation of the stylus 6 each time a machine 21 produces a piece) are processed and stored by pulse converter and amplifier stages 35, 36, selector circuit 39, totaliser 37 and preliminary store 38. A charge built up in capacitor 50 in stage 35 while switch s is open, discharges through a relay 52 each time a piece pulse causes switch s to close, operating switches 53, 54 so that a capacitor 55 charges and a transistor 58 is opened through a potential divider 59, 60. Whereupon an amplified signal from stage 36 energizes magnets 61, 62 which respectively advance a counter 8, Figure 1, and the totaliser 37. In the totaliser 37, switches 63, 64, 65 reverse after every tenth, hundredth and thousandth pulse respectively and other capacitors 74, 75, 76 are charged in step therewith, forming with capacitor 55 the preliminary store 38 of piece pulses. Transfer from store 38 to flip-flops 43, 41 occurs (with selector 39 set as shown) if there are charges on capacitors 74, 55 when the wiper 22 passes over contacts k 13 , k 14  discharge changing condition L to condition O, passage over k 12  having ensured previous return to condition L where necessary. On a machine 21, a switch r is closed while the machine is running and, each time the wiper 22 bridges contacts k 8 , k 16 , a transistor 80 is switched off, the coil 17 of the magnet M is deenergized and the stylus 6 is lowered into contact with the chart 7 to record the succession of strokes which form the band 31 registering running-time. If, while the machine is idle, one of the switches t 1  to t 6  is closed to indicate the reason for the interruption, the wiper 22 will bridge one of the contacts k 1  to k 6  and the contact k 16  repetitively to form, for example, the band 32. If either or both flip-flops 43, 41 are in O condition when the wiper 22 bridges contact 16 and contacts k 7 , k 9 , a stroke 34 and/or 33 will be recorded to register "tens" and "units" of production pieces (selector 39 being set as shown). To ensure that the marks 33 are individually distinguishable with a particular rotary speed of the shaft 10 say 5 r.p.m., alternative settings of the selector 39 make the marks 33 represent "tens" or "hundreds" and the marks 34 ten times as many. With passage of the wiper 22 over contacts k 10 , k 11  any residual charge in capacitors 74, 55 is cancelled to avoid any risk of it resetting the flip-flops to O condition. The contact k 15  is for producing the innermost band 79 indicating time and by making the outer point of reversal of movement of stylus 6 occur when the wiper is positioned over the middle of contact k 9 , the marks 33 are passed through twice. Various modifications are described with reference to Figures 5 to 9 (not shown).
