Compounds described herein are suitable for use in three-dimensional optical recording materials, etc. The transparent elastomeric compositions can be covulcanized with rubbers such as polybutadiene, polyisoprene, styrene-butadiene rubber, styrene-isoprene-butadiene rubber, isoprene-butadiene rubber, ethylene-propylene diene rubber or natural rubber. The seating assembly further includes a single, continuous seat back attached to each of the seat support members and spanning the entire pew seating area, such that the plurality of seat members are associated with the single, continuous seat back. A unique battery charging device is employed to maintain the two banks batteries in constant substantially full charge.
