Title: Apparatus for sorting punched cards for statistical purposes
Filed: 1928-07-26
Abstract: 295,353. Naamlooze Vennootschap Kamatec. Aug. 10, 1927, [Convention date]. Sorting cards.-In card-sorting apparatus the cards are read mechanically and while in motion, by reading - means which include a rotary drum having radial spring-pressed pins. The cards are fed from a magazine 2 through a throa,t 3 to rollers 7 and to the reading drum 8, having, as shown in Fig. 3, three sets of sensing pins 13. After being read the card is fed into the appropriate box 61. The reading pins 13 are carried on a disc 39 which is mounted on ball bearings 38 and is adjusted to read the desired card column by means of a screwed spindle 41 and a handle 42, Fig. 4, a rod 40 preventing rotary motion of the disc 39. These pins 13 coact with a slotted plate 9 and a toothed bar 14 pivoted on a shaft 15 and engaged by the forked end of an arm 16 attached to a shaft 17, so that movement of plate 14 oscillates this shaft 17 ; also attached to the latter is an arm 18 connected to a link 19 and a bell-crank 20 (pivoted at 22) carrying an arcuate member 21, Fig. 5 which is adapted to move a spring- mounted arm 25 on a disc 24. There is an arm 25 for each set of pins 13. The disc 24 rotates past pin 23 so that the end of an arm 25 moves over the pins 23 in synchronism with the passage of the reading pins 13 over the plate 9. If there is a hole in, say, the fifth position in the column the fifth pin 13 of a series passes through the cam and the plate 9 and moves the bar 14 about its axis 15 at the same instant that the end of an arm 25 is opposite the fifth pin 23. The rocking of plate 14 will operate the mechanism 16 - - 20 so that the part 21 forces the arm 25 to move the fifth pin 23 axially. To each pin 23 is attached an arm 27 which, when the pin 23 is moved axially, is pushed between a guide plate 28, Fig. 2, and the mouths of channels 29. The pin 23 is later restored by cam pins 26, Fig. 4, on the disc, 24. A chain 49 drives the sprocket 47, Fig. 2, of the reading drum 8 and carries arms 50 which are spring-pressed outwards and carry, at right angles, pins 51. Each pin moves between the plate 28 and the mouths of channels 29 until it meets a projected pin 27 and is thereupon moved into a channel 29, say the fifth. At the other end of the channels and spaced the correct distance from one another, are arms 33 on shafts 32, which through arms 34 and Bowden wires 35 operate the deflectors 36, Fig. 8. If a pin 51 is guided into say, the fifth channel it moves along until it meets the fifth arm 33 and thereupon at the appropriate instant moves the deflector of the fifth box to intercept the card, which has been moving along between the rollers 11, Fig. 1. Means are provided for removing the plate 14 out of the way of the sensing pins 13 when there is no card in the machine.

Abstract: 1472184 Ignition systems  VOLKSWAGENWERK AG 17 May 1974 [19 May 1973] 21951/74 Heading F1B In order to achieve a non-linear functional relation between the ignition angle and the engine speed, a pick-up 2 detects two marks, e.g. holes or pins 40 degrees and 80 degrees before top dead centre, on the engine flywheel, the first pulse initiating integration in integrators 14, 15, e.g. counters, the rate of integration in integrator 14 being varied in steps in accordance with engine speed by a first network 17 and an oscillator 16, and the rate of integration in integrator 15 being varied by a second network 18 in accordance with engine load, e.g. inlet manifold depression. The second pulse terminates integration, and delay of the sum in integrator 14 takes place until the sums in integrators 14 and 15 are equal, when an ignition firing signal is produced at 12 via a comparator circuit 21. As described, integrators 14 and 15 are counters. Forward counting is initiated by the first pulse, and backward counting in counter 14 only, by the second pulse. On the sum in counter 19 reaching a first figure during the forward counting, switching in frequency divider 17 occurs to charge the rate of counting. The circuit element 19 provides for switching in frequency divider 18 to produce frequency charges due to changes in load. A second pick-up 3 provides an ignition signal 180 degrees off-set from that provided by pick-up 2. The ignition timing may be varied in accordance with engine temperature (not further described), and individual circuits are given for the boxes of Fig. 4.
