Abstract: Electromagnetic exploration methods are used to identify a subsurface anomalous feature. This is sometimes difficult in the presence of large fields from the transmitter or other surrounding material that may be above and around the subsurface feature. By constructing linear combinations of the field and gradients of the field it is possible to remove the large fields associated with the transmitter and the surrounding material to make identification of the anomalous subsurface material easier. The fields and gradients can also be combined so as to provide estimates of other electromagnetic field quantities that would be otherwise difficult to measure, for example the electric field or the time derivative of the electric field.

Abstract: A polarization adjustment assembly for a reflector antenna is provided with a radio bracket with a mounting flange. The mounting flange is coupled to a hub provided with a stop portion. Fasteners couple the radio bracket to the hub via slots in the mounting flange, rotatable with respect to the hub within the extents of the slots. An adjustment bolt passes through a boss coupled to the mounting flange. The adjustment bolt abuts the stop portion, whereby longitudinal displacement of the adjustment bolt with respect to the boss rotates the radio bracket with respect to the hub. Alternatively, the positions of the boss and stop portion on the mounting flange and hub may be exchanged.

Guided in the first bearing surface is a second bearing surface of hollow cylindrical design, at least in sections. Rolling bodies are arranged between the bearing surfaces. The pivot bearing also has a cage for guiding the rolling bodies, and a slide block to prevent the cage from slipping. A first grove is formed in the first bearing surface and a second grove is formed in the second bearing surface. The groves are inclined transversely with respect to the running direction of the rolling bodies. The opposite inclination of the groves has the result that, if the spacing between the bearing surfaces is neglected, the grooves intersect. The sliding block is guided between the grooves.
