Abstract

The device converts each of eight binary inputs, represented by the binary permuted actuations of three switches 9a...9c, into a different one of eight respective positions 0...7 for output shaft 10. Switches 9a...9c can be relay or rotating switch actuated. The binary actuation of switches 9a...9c causes a corresponding binary energization of respective solenoid coils 11...13 by power source 8. Such coils surround a movable armature connected to shaft 10. Frame 15 supports coils 11...13. Frame 15 is comprised of coil spacers 18a and 18b interleaved with annular spacers 19a...19c between end plates 17a and 17b, which are all held in compression by bolts 16a and 16b. Outside end plate 17c and spacers 19d are fixed to plate 17b by bolts 20a and 20b. Shaft 10 is slidably received through plate 17c.

The device converts each of eight binary inputs, represented by the binary permuted actuations of three switches 9a...9c, into a different one of eight respective positions 0...7 for output shaft 10. Switches 9a...9c can be relay or rotating switch actuated. The binary actuation of switches 9a...9c causes a corresponding binary energization of respective solenoid coils 11...13 by power source 8. Such coils surround a movable armature connected to shaft 10. Frame 15 supports coils 11...13. Frame 15 is comprised of coil spacers 18a and 18b interleaved with annular spacers 19a...19c between end plates 17a and 17b, which are all held in compression by bolts 16a and 16b. Outside end plate 17c and spacers 19d are fixed to plate 17b by bolts 20a and 20b. Shaft 10 is slidably received through plate 17c.

Cylinder 21 of permeable material is fastened concentrically to plate 17a by bolt 22 located at one end of the armature. An initial adjustment of the position of the head of bolt 22 determines the smallest increment of motion for shaft 10. Bolt 22 can then be held in a fixed position by set screw 35. Screwdriver engagement-slot 22a can be used for later adjustment of the smallest output increment of shaft 10. The armature comprises a plurality of sections a...c having annular portions 23, into which cap 25 is threadedly received.

Bolt 26 is threadedly received into cap 25, except for the last cap 25c which receives shaft 10. The adjustmen...
