Abstract: The present disclosure relates to a primer for a personal firearm. The primer includes a primer cup including a cylindrical side wall closed at one outer end by a bottom; a pyrotechnic charge placed in the primer cup; an electrical component suitable for producing the thermal energy needed for priming the pyrotechnic charge, the charge being in contact with the electrical component; a printed circuit board, said printed circuit board having an internal face comprising the electrical component in contact with the pyrotechnic charge, characterized in that said printed circuit board forms at least in part the outer bottom of the primer cup.

Abstract: A tightening device for a wind turbine configured to fasten and/or tighten a plurality of fastening means to a fastening target object, wherein the fastening means are arranged in a fastening means circle is provided. The tightening device includes a center bearing unit for allowing the rotation of the tightening device about a center axis, a torque unit for applying torque on the fastening means to fasten and/or tighten the fastening means to the fastening target object, and a first arm extending in a radial direction from the center bearing unit and supporting the torque unit.

Abstract: A carrier that mounts to a vehicle. In some embodiments, the carrier may include a pair of arms to support a bicycle. Each arm may include one or more securing devices each including a strap to contact a frame region of a bicycle and a pair of buckles to fasten the strap over the frame region. In some embodiments, the carrier may include a mount for a vehicle hitch. The mount may include a pair of user-actuated coupling members, such as a wedge member and a retractable retainer, each configured to attach the mount to the hitch. One of the coupling members (e.g., the retainer) may serve as a backup for the other coupling member to improve safety. In some embodiments, the carrier may include a mast that is releasable for backward pivotal motion away from the vehicle.

Abstract: A drop down door system for a vehicle in which a door is pivotally connected adjacent its lower edge margin for swinging between closed and open positions relative to a door opening framed at opposite sides by door jamb members. Elongate tension springs extend between the doorjamb members and opposite edge margins of the door. The doorjamb members have elongate channels for receiving the retracted springs, which channels are covered by portions of the door when it is closed. Hinge mechanism for the door is provided by aligned hinge sleeves on the door and door frame with an elongate hinge pin extending therethrough which has stop mechanism thereon for inhibiting movement of the pin from its selected assembled position.
