Abstract: Techniques for energy production are disclosed. A kinetic fabric for use in a kinetically-activated energy production system is implemented. The kinetic fabric comprises a three-dimensional, layer-based flexible matrix that regains shape after deformation. The fabric further comprises a kinetically activated energy source layer supported between layers of the flexible matrix. The fabric further includes a flexible electrical connection that provides an electrical path between the energy source layer and a terminal on the flexible matrix. The kinetic fabric is deformed with mechanical agitation, and energy is harvested from the energy source layer through the terminal on the flexible matrix. Various embodiments are disclosed including flags, moving vehicles, and shade structures, among others.

Abstract: The high temperature properties of an article having at least a portion of its surface formed of an arylene sulfide polymer is improved by treating such article with a treating agent selected from the group consisting of hydrogen peroxide, an alkali metal or alkaline earth metal hypochlorite, sulfuric acid, chlorine, sulfuryl chloride, nitrogen dioxide, chromium trioxide, alkali metal permanganates and nitric acid under conditions of concentration of treating agent, time and temperature to effect the desired improvement. Treated articles such as coated substrates and moldings exhibit increased high temperature surface hardness. Articles such as fibers, yarns, fabrics and films exhibit infusibility at 700.degree. F. (371.degree. C.).

Abstract: An audio signal mixing apparatus requiring no active elements, for a conventional audio amplifier unit having a tape monitor function. Low level signal inputs are level-controlled by potentiometers, mixed, and supplied to the phono input of the conventional amplifier. With the conventional amplifier unit set in the phono and tape monitor modes, the mixed low level signal is preamplified by the input amplifier stage of the amplifier unit and provided to the tape monitor output of the amplifier unit. High level inputs to the mixing apparatus are controlled by respective potentiometers and mixed before being supplied to the high level input of the conventional amplifier unit. A switch in the mixing device allows the preamplified signals from the tape monitor output of the amplifier unit to be combined with the high level inputs and provided to the tape input of the conventional amplifier unit.
