Abstract: A method of indicating a characteristic of a soil sample of a field includes measuring a co-factor in the soil sample and using the co-factor to place the soil sample in a soil sample group. The characteristic of the soil sample is measured and then is scaled based on the soil sample group. The scaled measure is displayed to better represent the characteristic of the soil sample relative to soil samples of the sample group.

Abstract: A stabilizer (10) for an in-ground member (12) includes: a mounting collar (16) having a channel (18) extending therethrough; a plurality of arms (20a-20d) having respective collar ends (30a-30d), the collar ends being adapted to extend through the channel and engage with the mounting collar; and a resilient member (40) being sized (a) to be disposed within the channel between the collar ends and (b) to be engaged by the in-ground member so as to urge the resilient member against the collar ends to force the collar ends against the mounting collar, whereby to rigidify the stabilizer. A method is disclosed for installing the above-described in-ground member into the ground to dispose a portion of it beneath the surface of the ground and to leave a portion of it extending above the surface of the ground.

Abstract: A rotary tool for working in a cramped and possibly hostile environment. The tool can be clamped into position and left to work automatically. The tool has a resiliently biased pin and a ratchet driven cam for ensuring that the working unit cannot become overloaded. Working cannot go beyond a preselected level owing to the action of the ratchet driven cam which is only stepped to a certain level on a flange which strikes a lever when that level is reached. The work done can be cutting, welding preparation or trepanning.
