Abstract: A scaffold for ergonomic positioning and reliable support of foot-control pedals of musical instruments is disclosed. The scaffold includes a three-walled channel for engaging the distal portion of the base of typical known keyboard control pedals. The scaffold is securely positioned for optimal foot access on the floor by means of a fixation socket which is engages an adjacent floor tube of a typical stand. The foot-pedal channel is adapted to engage the typical pedal base by friction and interference clamping to support its active elements at an ergonomic height and angular orientation during an energetic live performance with the keyboard player sitting and standing during different portions.

Abstract: Processes for polyphase fluid extraction of concentrated, active therapeutic components from parts of plants identified taxonomically as Symphytum, Taxus and Aloe species are described. The resulting products-by-processes are defined as Concentrated Fluid Plant Extracts (CFPE) of the respective plant types, where P can be S, T or A. The preparation process for CFPE includes multiple/sequential stages of diffusional transfer of the active constituents into liquid and/or vapor extraction phases under contact conditions of forced convection at controlled temperature and pressure. Therapeutic formulations based on CFPE including emulsions, aerosols, liposomes and controlled-release devices are presented. Treatment methods for a variety of skin conditions and complications of specific diseases are indicated.
