Abstract: An ink container for an ink delivery system in an inkjet printer, the ink container including a bottle for holding a supply of ink, a cap attached to the bottle to form a hermetic seal therebetween, the cap including an air inlet channel and an ink exit channel, and a color indicator ring having a key projecting therefrom. The color indicator ring resides between the ink bottle and the cap and is capable of being fixed in a plurality of predetermined orientations, with each orientation corresponding to a predetermined angle between the key and a line defined by the air inlet channel and the ink exit channel. The inkjet printer includes a plurality of receptacles, each adapted to receive a corresponding ink container containing an ink of a different or predetermined color. Each receptacle has an ink reservoir attached at the base thereof and includes a vertically oriented groove located at a predetermined position on the sidewall of the base.

Abstract: A high speed electromagnetically actuated electromechanical switch is provided by a bistable electric snap blade operated by an electromagnetic actuator. A magnetically permeable yoke directs the flux paths of a pair of coaxial coils. An armature plunger shuttles axially reciprocally in the coils between first and second positions. The snap blade has a pair of cantilever arms extending towards each other to engage the armature plunger in the gap therebetween for lateral flexing actuation. Energization of a given coil provides a primary flux path around that coil through the yoke and the armature plunger, and provides a secondary flux path around both coils through the yoke and the armature plunger. The primary flux path force around either coil is always stronger than the secondary path.
