Abstract: A retention assembly for retaining a plurality of elements in a stator slot of an electric machine is provided. The retention assembly may include a stator wedge fixedly positioned in a dovetail in the stator slot to retain the plurality of elements; a top ripple spring between the plurality of elements and the stator wedge; and at least one shim positioned between the stator wedge and a load bearing surface of the dovetail. A method may include compressing the stator wedge in the stator slot from a first position thereof relative to the dovetail of the stator slot, the compressing creating a gap between the stator wedge and the dovetail. A shim may be inserted in the gap; the compressing released such that the shim retains the stator wedge in a second position that is more compressed relative to the plurality of elements in the stator slot compared to the first position.

Abstract: An electrically insulating composition comprising about 25 to about 55 percent by weight of filler materials, about 45 to about 75 percent by weight of resin. The percentages being selected such that the total percentage of components does not exceed 100 percent. The composition has a thermal conductivity of about 0.2 to about 1.3 W/m-K when measured at 130° C.

Abstract: Embodiments of the disclosure can include a method for reducing or repairing vibration-caused damage in a stator bar, and a dynamoelectric machine resulting therefrom. The method for reducing vibration-caused damage in a stator can include applying, from within a ventilation slot of a stator core, a liquid based vibration-absorbing material onto a side ripple spring, the side ripple spring being in contact with a stator bar and the stator core; and allowing the liquid based vibration-absorbing material to cure, wherein the cured vibration-absorbing material remains in contact with the side ripple spring for absorbing stator vibrations.

Abstract: The present invention is directed to novel device comprising a sol-gel filled microchannel and methods for purifying nucleic acids from biological samples. In one embodiment shown in FIG. 1, the microfluidic device (1) comprises a base (2) with a microchannel (3) formed in the interior of base (2), wherein said microchannel (3) is filled with a sol-gel matrix and in fluid communication with an inlet port (4) and outlet port (5) wherein inlet port (4) and outlet port (5) are formed on the exterior surface (10) of base (2). The device may be further provided with additional components to allow for analytical analysis of the purified nucleic acid sequences.

Abstract: A wiping material in the shape of a cup and a handle for holding the material during its use. The wiping material may include several layers with the same or different compositions. For hygienic use, it may have a layer of soft, absorbent toilet paper with, perhaps, an innermost layer of a moisture-impermeable material. The handle typically fits inside of and grasps onto the cup-shaped wipe. Conveniently, a compressible sponge on the end of the handle and slightly larger than the inside of the wiping material retains the material for use. The handle may also eject the wipe after such use. A plunger connects to a shaft in the handle which in turn connects to a washer or some other surface near the sponge. Depressing the plunger moves the cone of material off the sponge where it may fall into some receptacle. A spring within the handle biases the plunger and shaft back into its former position. Utilizing the combination involves placing the handle next to the cone of material and connecting the two together.
