Abstract: A passively activated switch system for a high-current coil including a plurality of silicon-controlled rectifiers (SCRs) each electrically coupled to a high-current coil, each SCR electrically coupled in parallel to a fast-acting mechanical switch. A passive voltage detector is responsive to an increase in voltage above a predetermined threshold value indicating a start of an over-current event which closes each of the plurality of SCRs to enable a loop current to create a large electromagnetic force. Each fast-acting switch is responsive to the large electromagnetic force and is configured to close to shunt current from each SCR to prevent damage of at least one of the high-current coils or a system that utilizes a high-current coil, or both.

Abstract: A sled includes a deck having a top surface and a cradle section configured to hold a shipping vessel. The cradle section includes a length that extends from a back of the deck towards a front of the deck. First and second wedges extend at least the length of the cradle section and each include at least an outer facing surface and an upper facing surface. The outer facing surface of the first wedge defines a first side of the cradle section and the outer facing surface of the second wedge defines a second side of the cradle section. The upper facing surfaces of each of the first wedge and the second wedge is oriented at an angle relative to the top surface of the deck such that each upper facing surface of each wedge slopes downwardly from an outer edge to an opposing inner edge.
