Abstract: A support system for an acoustic instrument has connecting elements of flexible material extending between and attaching the instrument and a support frame to support and/or balance the weight of the instrument and isolate acoustic frequencies, thereby eliminating deleterious acoustical effects. Embodied exemplarily herein as a support system for a drum, flexible elements extend between and attach the drum head hoop to a circular frame or support that fully or partially encircles the drum. The flexible elements may be made integral with the drum head and/or its head skin.

Abstract: The present invention comprises a mixture of hydrocarbons having a well-defined chemical composition that is suitable for use as a dielectric coolant in electrical equipment in general, and specifically in transformers. The dielectric coolants of the present invention are particularly suited for use in sealed, non-vented transformers, and have improved performance characteristics, including decreased degradation of the paper insulating layers, as well as a greater degree of safety and environmental acceptability. The present dielectric coolants comprise relatively pure blends of compounds selected from the group consisting of aromatic hydrocarbons, polyalphaolefins, polyol esters, and natural vegetable oils, along with additives to improve pour point, increase stability and reduce oxidation rate.
