An improved arrangement for adjusting crawler-type transport assemblies in a self-propelled construction vehicle between two differing home positions. The nodes are interconnected by a dual concentric ring topology. The hand-held tool has two ends, a bending die with an alignment notch in one end and a clamp with a clamping notch on the other end. Example application circuits include, but are not limited to reference circuits, operational amplifiers, comparators, analog-to-digital converters, digital-to-analog converters as well as other circuits that employ current mirror circuitry. Processes are described for making the copolymers at high molecular weight with the ketones randomly dispersed on the copolymer. 01-1 monomer, per one molecule of the copolymer on average, having a functional group capable of reacting with the crosslinking agent of c); and c) 0.
