摘要: A linear guide (1) having at least two rail elements (2, 2′) which are movable counter to each other in the longitudinal direction, wherein each rail element (2, 2′) has running surfaces (3, 3′) which, together with running surfaces (3, 3′) of a rail element (2, 2′) moveable counter thereto, form tracks (4) for receiving rolling bodies (10) and sliding bodies (11) between the two rail elements which are moveable counter to each other, characterized in that at least one sliding body (11) and at least two rolling bodies (10) are provided in each track (4) between two rail elements (2, 2′), wherein at least one rolling body (10) is arranged in each case on both sides of a sliding body (11) in the longitudinal direction of the track (4).

摘要: A power transmission system for use with downhole equipment in a borehole includes a power source that is positioned at the surface providing a DC power supply, a downhole DC/DC converter and a two-conductor cable connecting the power source and the downhole DC/DC converter. The power transmission system receives the DC voltage supply as an input and provides an output DC supply at a different voltage to the DC power supply for provision to the downhole equipment.
