Abstract: Position identifying transducer using a pair of serially connected magnetoresistive elements with an output terminal at their juncture and which lie in a common plane with the flux-sensitive areas of each element symmetrically disposed about a common center line that is transverse to the direction of motion of the transducer through a variable flux field. This arrangement permits identification of specific locations by providing a peak signal at a predetermined location regardless of the direction of relative motion between the transducer and flux field.

Abstract: 1300787 Electromagnetic actuators INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1970 [22 Dec 1969] 58653/70 Heading H1P [Also in Division B6] A print hammer actuator assembly comprises a yoke 141 carrying an electromagnet winding 144 and pivotally supporting an armature 148, the yoke 141 itself being pivotally mounted at 138 on a support 139. A spring 135 urges the yoke 141 against a stop leg 139b. The armature 148 is coupled to a print hammer 160 by a connecting rod 182 which is urged against the armature by spring 184.
