circuits (50, 52 and 54), (also referred to by Gillett as
secondary structures), and that the secondary structures (50,
52, and 54) “are separable from the remainder of the circuit
thus far described, resulting in two complementary subset
structures (120 and 140).” (See col. 3, lines 58-61). Figure
(2)of Gillett shows (col. 3, lines 61-63) subset (120) which
includes most of the heavy and bulky elements and figure (3)
shows the other subset (140). In use, subset (120) might be
carried by a machine frame and subset (140) might be part of a
circuit card pluggable into the machine frame (col. 3, lines
63-66). The organization described (figures 1-3) provides a
replaceable circuit package, which may be either the base
portion (120) or the card portion (140) (See col. 4, lines 5-
7, and figure 4). The load (functional card 160) incorporates
subset (140) in addition to the operational circuits normally
found on a functional card. Any necessary control/regulation
signal, as on line (42) is fed back from the load (functional
card) to the power supply (36) via magnetic coupling “a small
signal version of the flux link connectors” (col. 5, lines
(See col. 4, lines 12-16, and col. 5, lines 11-18).
