Abstract: Methods for assessing the result of a surface treatment carried out on a workpiece by particle blasting are disclosed. It is generally common to known automatic methods that they directly determine the covered portion of the surface. Proceeding from the usual definition of the usual 98% degree of coverage as “completely blasted” results in an error in the determination of the corresponding area of 1% to a distortion of the measurement result by 0.98%. In the disclosed method measuring points are identified as not hit by a particle of the particle beam when both a detected surface level is above a level located about a predetermined height threshold value lower than a target level, and a detected gradient falls below a predetermined gradient threshold value.

Abstract: Jettisonable sabot for a subcaliber projectile. In a jettisonable sabot for a subcaliber projectile, which is fired from a weapon barrel having helical grooves, there is a risk that individual segments of a sabot body, strike the projectile body with their edges during the separation from the projectile body, with these impacts against the projectile body impairing the impact accuracy. In order to avoid these impacts, the parting planes or slots between the individual segments of the sabot body are not arranged radially, as in the past, but rather parallel with radial planes with a specified distance (d) corresponding to at least half of the radius (R) of the projectile body, with the slits between the segments of the sabot jacket preferably being arranged parallel to radial planes with a specified distance (d).

Abstract: The following specification describes a pin contact formed from a stamping with the insertion end of the contact having bevelled end edge surfaces for enabling opposing pin contact external surface ends to engage for providing a closed juncture at the insertion end of the pin contact.
