Patent GB-551943-A (GB)
Abstract: 551,943. Totalizators; counting apparatus. TOTALISATORS, Ltd. (Julius, G. A.). June 6, 1941, No. 16016/42. Divided out of 551,919. Drawings to Specification. [Class 40 (i)] [Also in Group XIX] The adding unit of a totalizator comprises a number of counting elements coupled by slipping clutches with a constantly rotating shaft. Each element is normally locked by an arm carried by the cage of an epicyclic gear of which one sun wheel is driven by an escapement operated by incoming impulses and withdraws the arm from engagement with the counting element and of which the other is geared to the counting element so as to bring the arm into the stopping position when the element has travelled a distance corresponding to the number of impulses received. The escapements of tens and higher denominations are rocked mechanically on the completion of the rotation of the element of the next lower denomination, or on the completion of half a rotation of the units element which makes a rotation for 20 receiving impulses. The invention is described with reference to a system identical with that described in Specification 551,919. Specification 551,942 also is referred to.

According to the invention there is a drive motor 16 for the hollow shaft 30, the motor 16 having a drive shaft 15 that is axially displaceable from an inactive rest position 26 to a position 25 in which it drives the shaft 30, and thence axially to a further setting 24 in which it pushes the rod into the shaft 30 to to loosen the chuck therein. The motor 16 can be used to bring the package 1 up to speed before the package is brought into engagement with the driving roller 4. Similarly the motor 16 can be used to brake the package 1 prior to its being doffed. In Fig. 1 a spring system moves the motor 16 to the setting 25 unless a piston and cylinder unit 17 is activated to move the motor 16 to position 24 or 26.  Figs. 5 and 6 (not shown) show how the motor 16 may itself be the piston in the cylinder of the unit 17. Fig. 5 shows a separate brake (14) for stopping the doffed package. Fig. 7 (not shown) illustrates how two bobbin holders may be mounted in parallel on a bobbin-changing assembly (32) of a continuous winding apparatus so that as one bobbin holder (3') is swung away from the package drive drum 4 it moves towards the apparatus associated with the piston and cylinder unit 17; and the bobbin holder (3") that was previously aligned with the piston and cylinder unit 17 moves towards the drive drum 4.

Fig. 1 shows 3 PCM exchange stores SV1, SV3, SV3 each with 32 8-bit rows. In a 64-bit delta-modulation system period, bit times 0-7 are used for a frame code word, bit times 8-10 are not used, bit times 32-39 are used for switching-characteristic bits and the other 45 bit times are used for respective delta-modulation channels. Bits relating to two such 64-bits sequences received concurrently on lines LD1, LD2 are distributed as shown to the stores, row 0 of SV1 and SV3 each receiving an 8-bit frame code word, row 22 of SV1 and SV3 each receiving 8 switching-characteristic bits, rows 0 and 16 of SV2 not being used, and each other row receiving a respective deltamodulation bit into its 1st bit position. Assuming 4 delta-modulation system periods per PCM system period, 3 further pairs of 64-bit sequences are loaded in turn into the same locations except that the 2nd, 3rd and 4th bit positions are used instead of the 1st bit positions for the deltamodulation bits. During bit times 0-10 of the next delta-modulation system period, the deltamodulation bits stored are transferred to the 5th, 6th, 7th and 8th bit positions of the row The stored information is transmitted as 8-bit PCM words, 4 filler bits being added to each 4 delta-modulation bits. If the number of deltamodulation system periods per PCM system period is more than half the number of bit positions per row in the stores, transfer into another exchange store is used in place of transfer into the second halves of the rows.
