Abstract: 986,125. Electric digital calculators. R. E. WELLS. Aug. 8, 1961 [Aug. 10, 1960], No. 27127/63. Divided out of 986,124. Heading G4A. An accumulator for adding and registering values has a plurality of sections, each section comprising essentially a binary accumulator the binary accumulators of each section representing multiples of different units, each section being connected to the next higher section by a selector switch. The accumulator is applied to the automatic bookmaking machine of the Specification 986,124 and employs as bi-stable stages the double action relays described in U.S.A. Specification 2,558,067. Each of these relays such as the relay ¢CIR has two stable states for its striker arm labelled #, which controls holding contacts 2C, 3C and operative contacts 1C, 4C, all these four contacts being changed over when, in response to an input pulse, the arm # is moved to its other stable state. The accumulator shown in Fig. 4 may be a "pay" accumulator for the bookmaking machine of Specification 986,124 and comprises three Sections (A), (B) and (C), Section (A) having binary stages representing ú¢, ú1, ú2 and a stepping switch for ú4 denomination; Section (B) having binary stages representing ú5, ú10, ú20 and a stepping switch for the ú40 denomination; and Section (C) having binary stages representing ú50, ú100, ú200 and a stepping switch for the ú400 denomination. Figs. 3, 3A show Section (A) in more detail, the section comprising accumulator relays ¢ CIR, 1C2R and 2C4R for denominations of ú¢, ú1 and ú2 respectively and a stepping switch "ú4 UN1" having five banks A-E of 25 contacts in each bank for the ú4 denomination. Assuming that a total "pay" value of ú3¢ supplied from the contestant odds calculating equipment (not shown) is to be registered, a line 1HP, Fig. 3, is marked to operate an input relay A, and marking potential is applied via contacts ¢P, 1P, 2P to input lines ¢B, 1B, 2B. The potential on line ¢B is applied via contacts 3C of a relay ¢B and TR to operate the accumulator relay ¢ CIR, thereby closing its contacts 1C and 5C to apply potential via contacts 4C of relay ¢B and TR to mark an indicator output line ¢PR which may be connected to provide a visual indication that registration has been effected. Furthermore, potential is applied via contacts 1C of relay ¢CIR to a lamp circuit ¢B/T. Registration of the ú1 and ú2 amounts in relays 1C2R and 2C4R is similarly effected. Assuming that a further total pay value of ú3¢ is to be registered, the F windings of relays ¢C1R, 1C2R and 2C4R are energized to attract the striker arms = and # in the opposite direction to that described previously. Also, potential is applied over contacts 7C of relay ¢C1R to energize a carry-over relay 1CHR to apply potential to the winding N of relay 1B and TR and hence via contacts 2C thereof to energize relay 1C2R thereby effecting registration of a ú1 value. The relay 1CHR is now restored over contacts 1C of relay 1B and TR. In a similar manner, relays 2CHR and 4CHR are operated, operation of the latter causing potential to be supplied via contacts 2C of relay 4B and TR to operate the coil of stepping switch ú4 UN1. Wipers D and E of the switch ú4 UN1, when in any of contact levels 2-5 of the switch, contact levies 5CH, 5CB connected to a relay 5 CHR in Section (B) of the accumulator. Wipers B and A of the switch ú4 UN1 are connected to indicator lamp lines 1 B/T and 2 B/T to provide appropriate value indications for the ú1 or ú2 values which remain after the ú 5, ú10 &c. has been transferred to accumulator Section (B). In order to provide for a maximum registration of approximately ú100,000 a final accumulator Section (Fig. 5 not shown) receiving inputs from Section (C) is provided. This final section comprises uniselector switches for amounts of ú 500, ú1,000 and ú 5, 000, having banks of 25 contacts.
