  • Patent number: 4215383
    Abstract: The present invention relates to an electrical circuit for current regulation in DC motors including a sensitivity control means therefor. The circuit includes a means for sensing a predetermined current level in the load of a DC motor. In combination therewith is a subcircuit for cutting-off the load current when the predetermined current level has been reached. Additionally, there is provided means for restoring the load current when, after load current cutoff, the inductive motor current has fallen to a level sufficient to restart the subcircuit.

  • Patent number: 4193444
    Abstract: The present invention constitutes an electrical mounting and conduction means having a support element having a generally U-shaped interior surface, the base of the exterior of the support element being in thermal contact with a heat dissipating surface; a carrier element having a generally U-shaped exteriorsurface, the surface having a cross-section of smaller dimension than that of the U-shaped surface of the support element, the carrier element being nestable within the support element; and locking means removably securable to adjacent arm members of each of the support and carrier elements for maintaining the support and carrier elements in selective securement to each other.
