Abstract: 203,734. Perkins, A. April 13, 1922. Statistical machines.-Each of a stack of cards, tallies, checks, &c. is provided, adjacent only to one or more of its edges, with a series of perforations b, each perforation being so placed that it may be directly slotted out to the edge of the card. The hole or holes corresponding to the characteristics it is desired to record on each particular card are slotted as at c to the edge of the card. To sort out any particular card or cards one or more rods or wires e are passed through the holes in all the cards corresponding to the characteristics of those particular cards it is wished to sort, so that these cards, being slotted to the edge, are left behind when the rods e are raised, while all the cards not slotted at the particular perforation are lifted by the rods. In the example illustrated the card a<1> relating to sub-code B and operator's code 7 would be left behind and the rest of the cards lifted by the rods e passing through the holes B and 7 of all the cards. In cards thus sorted into groups the various slots c will form slots along the edge of the stack of cards so that an incorrect card will be readily detected by its uncut edge. In a stack of cards bearing mixed cards from 1 to 99,999 to sort out card 2565 the rod is placed through the " 2 " in the thousands and all cards in the two thousand series are sorted out. From these, all cards in the two thousand five hundred series are sorted out, and so on in successive stages to the card 2565. The tallies &c. may be punched out in metal.

Abstract: 869,665. Driving generators. WASAGCHEMIE A.G. April 2, 1958 [April 4, 1957], No. 10669/58. Class 35. An electric detonator comprising a generator driven by a mainspring through a gear-wheel is provided with means to prevent rotation of the gear-wheel during winding of the mainspring and to ensure that the gear-wheel is free to rotate during unwinding of the mainspring. The mainspring 7 is wound by a shaft 5 which it counter-rotates when it unwinds. A gearwheel 14 is coupled to the shaft by a pawl 13 and ratchet 12 so that, during winding the rotation of the shaft will not be transmitted to the gear-wheel, but during unwinding it will. An arresting device 15 meshes with the teeth of the gear-wheel during winding to positively prevent rotation thereof, the arresting device being urged into this position by a leaf-spring 52; subsequently, to permit unwinding, it is moved away to position 15<SP>1</SP> to free the gearwheel by manual rotation of shaft 19 carrying a claw 18. A cam 46 blocks the device 15 in each of its positions, this cam being momentarily moved aside at the beginning and completion of the winding and unwinding cycles by an arrangement of gearing and cams (Fig. 3, not shown). The gear-wheel 14 drives the armature 22 of the generator which is provided with contact segments 36 carried on a ring gear 35 and so disposed that they contact bolts 40 connected to terminals 4 and fire the detonator when the generated current reaches its maximum value.
