Abstract: Disclosed are transverse and/or commutated flux machines and components thereof, and methods of making and using the same. Certain rotors for use in transverse and commutated flux machines may be formed to facilitate a “many to many” flux switch configuration between flux concentrating stator portions having opposite polarities. Other rotors may be formed from a first material, and contain flux switches formed from a second material. Yet other rotors may be machined, pressed, stamped, folded, and/or otherwise mechanically formed. Via use of such rotors, transverse and/or commutated flux machines can achieve improved performance, efficiency, and/or be sized or otherwise configured for various applications.

Abstract: A carbon dioxide cartridge is triggered when a lance with a piercing tip punctures its burst disc. The cartridge has a cap that has an outlet and a passage for the lance and puncturing tip to travel. The lance is pushed into the burst disc when a heat expanding substance which is stored hermetically the cap in such a way that the only direction to expand is to displace and push the lance right into the burst disc. Once the burst disc is pierced, the cartridge empties its contents quickly out the outlet. In at least one embodiment the cartridge and the cap are attached by screw threads.

Abstract: An apparatus and method for ejecting fluid from a fluid delivery system. The fluid delivery system has a pneumatic assembly that when triggered injects gas into a hydraulic assembly, which in turn ejects fluid through an external interface. An electronic interface displays various measurements, for example, how much fluid has been ejected and if the hydraulic system is closed the pressure of the system. The pneumatic assembly can also be depressurized such that fluid can reenter the hydraulic assembly through the external interface.

Stator tooth overlap may reduce hysteresis losses, for example losses in flux concentrating portions of an electrical machine.
