The subject invention is a carrier or product formed of a matrix having starch, sugar, fat, polyhydric alcohol and water in suitable ratios such that there exists a water activity of 0. The magnetic pole faces of the rotor lie in an ellipsoid. The first brake wire can cross over the second brake wire at least once and possibly twice, each time in a direction transverse to the first direction. A terminal of C1 that is not connected to Ein and a terminal of Q2 that is not connected to Q1 are connected. Plus, a further iteration facilitating manual adjustment of air-gun thrust-pressure.
