Abstract: The cable dispensing system includes multiple parallel coils of flexible non-insulated cables separated by multiple parallel insulating discs. The insulating discs have hubs to which the inner portions of the coils are fixedly coupled. The insulating discs and coils are disposed within a housing, which is rotatably coupled to the multiple parallel insulating discs and fixedly coupled to each outer portion of the multiple coils. The cables comprising the coils are routed from the inner portions through tunnels, which extend through the insulating discs in paths parallel to the axis of the parallel insulating discs. When cords attached to the housing are extended, the coils become wound, creating an electrical short between adjacent loops of the spiral coil. The shorter conductive path reduces the amount of energy that is lost as heat.

Abstract: A platform includes main transverse beams ('MTBs'), each supported by at least one hoist. It is determined whether a load on any MTB is different from the load on any other MTB by more than a predetermined amount.  An MTB which has a load different from the load on any other MTB by more than a predetermined amount is selected and then vertically moved with respect to the other MTBs within a predetermined safety limit to transfer load between the selected MTB and the other MTBs while monitoring the loads on each MTB and the position of the selected MTB as vertical movement of the selected MTB  proceeds. The monitored loads and position are compared with the safety limit;    and the movement of the selected MTB stopped when either the desired load transfer is completed or the safety limit has been met.
