A cast-in anchor system for anchoring objects to concrete structures. The preferred system uses an extruded cast-in anchor and an extruded bolt retainer. The cast-in anchor is embedded within concrete with a face left exposed. The bolt retainer has a bolt inserted through it and is placed within an anchor channel on the exposed face of the cast-in anchor.

In another embodiment, a continuous metal foil tape is fed into a bead blasting box and at least one surface of the metal foil tape is abraded with TiN powder delivered by a bead blasting nozzle located within the bead blasting box. Accordingly, a cathode having increased capacitance capability is provided to more closely match the capacitance of a poly-anode stack.

The keybar that is attached to the frame of a dynamoelectric machine is broken into a bald keybar with mini-dovetails attached to it. The bald keybar is identical to the bolt portion of a conventional keybar. The mini-dovetail is a trapezoidal or U-shaped strip with insulated slanted arms. The core packet is inserted loosely over an array of mini-dovetails. Devices such as wedges, threaded rods flex the slanted arm and press them against the slot faces of the core packet, thereby locking the core packet to the frame. Insulation on the slanted arms prevents large eddy currents due to shorted laminations, increasing the machine efficiency. Preventing large eddy currents also eliminates hot spots which could otherwise cause a core failure. Locking the core packets also prevents rattling of laminations. The locking method also distributes the torque forces evenly around the periphery.
