  • Patent number: 10348142
    Abstract: A stator of an electric machine has an annular stator body with a multiplicity of winding slots. The winding slots protrude into the stator body in the manner of a pocket from a ring interior. Respective windings are disposed in the winding slots and the slots are sealed toward the ring interior with slot-liner elements. The slot-liner elements of all the winding slots are combined to form a slot-liner cage. The slot-liner cage is formed with circumferential cage rings at the ends of the slot-liner elements. The cage rings have an interruption at a circumferential point. The circumferential point has a self-retaining lock geometry which prevents an autonomous opening of two intermeshing ring ends of the cage rings.

  • Patent number: 10149943
    Abstract: A cartridge interface assembly drives a stopper in a drug reservoir or a drug delivery device. An anti-rotational guide optionally moves along an axis of a cavity of the reservoir. The anti-rotational guide is optionally slidably anti-rotationally coupled to a housing of the drug delivery device. A telescoping plunger driver may include a proximal shaft and distal shaft that telescope by relative rotation. The distal shaft is optionally slidably anti-rotationally coupled to the anti-rotational guide. The shafts are optionally oriented along said axis. In some embodiments, rotating the proximal shaft with respect to the anti-rotational guide moves the guide along said axis with respect to the housing and moves the distal shaft along the axis with respect to the anti-rotational guide.
