Title: Improvements in and relating to record card controlled accounting machines
Filed: 1931-07-01
Abstract: 385,965. Statistical apparatus. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. July 1, 1931, No. 19005. Convention date, July 14, 1930. [Class 106 (i).] In a record-card-controlled machine a group control mechanism is provided to detect changes in designation columns of the card and to initiate a total-taking operation. The mechanism comprises adjusting members for controlling a recording means and adapted to be adjusted for each successive card by a reading member co-operating with an individual card column, and a control member allotted to each adjusting member, the movement of the control members being in a direction transverse to that of the adjusting members. The transference of the denominational values from a code card are effected in a known manner as described in Specification 375,310. In the known arrangement, a card lever 4 co-operates with contacts 5 to close the circuit of an electromagnet 6, the armature of which controls the setting of a set of four adjusting members or discs 13 .. 16 and determines the movement of a numeral type-wheel 28. The type-wheels 28 are driven by a motor through friction clutches on a shaft 26 and the movement of the wheels 28 is arrested when a pawl 30 thereon engages the aligned notches in the sets of discs. The discs have graded projections 13a .. 16a which are successively engaged, for setting the discs, by the projection 21 on a lever 12 connected to the armature 9 and a pivoted arm 11. The arm 11 co-operates with a stepped cam 22 on the operating shaft 47 ; this shaft carries a second cam 27 that co-operates with a lever 25 adapted to effect the restoration of the control discs at each cycle of operation. In accordance with the present invention, the discs are provided with projections 33 for co-operation with a corresponding double-armed control member or lever 34 pivotally mounted on a rod 35 secured to the free end of an arm 42. The levers 34 have notches 36, 37, in one of which rests a rod 38 secured to an arm 39 connected to a lever 40 pivoted on the arm 42. The lever 42 carries a pin 45 co-operating with a notched cam 48 on the shaft 47. When the first card of a group is being read the lever 42 is lowered to cause the levers 34 to move into the path of the projections 33 and one or other of the levers 34 is rocked by the adjustment of the corresponding disc 13 .. 16 to cause the rod 38 to engage the other notch 37. This setting of the rod 35 in the notches 36, 37 is maintained during each tabulating operation by the lowering of the lever 42 until a card with a different identification perforation is felt, whereupon the appropriate lever 34 is rocked and the rod 38 is displaced with respect to the rod 35. This movement effects the closure of a contact 44 which contact is arranged in the circuit of an electromagnet 50, Fig. 3. Energization of the magnet releases a clutch 53 from the card-feeding mechanism 54, 62 and engages it with a mechanism 59, 60 driving the shaft 61 of the totaltaking mechanism.

Fig. 11 shows an arrangement in which a ceramic plate 11 is initially in-plane polarized by a potential applied to an interdigitated pattern of electrodes 10 through terminals 15, the terminals being subsequently short circuited. A matrix of heating conductors is provided by parallel sets of tin and gold conductive stripes on respective glass plates 12, 13 adhered to the ceramic plate, the combined heating effect of selected co-ordinate stripes being sufficient to substantially reduce the polarization adjacent their crossing points. The localized change in optical characteristics of the plate is sufficient to produce corresponding dark regions when light from a source 1 is passed through a polarizer 3, the plate assembly 10, 11, 12 and an analyser 7. In a modification, Fig. 14, the conductive pattern 17 shown is used to provide a selectively operated two digit display.
