摘要： A dual-string tension dynamometer (1) utilizes two strings (10, 11) wrapped around approximately ninety degrees of a test wheel (12). The lateral forces (E, F) are balanced such that the total lateral force net value is zero. The results reflect purely torsional loading.

摘要： Improvements in material-to-material connections are provided. For example, metal-to-metal connections are improved, such as the interface connection between a dental handpiece bur tube (10) and a component such as bearing (12). At least one marking, such as a laser marking (20) is provided such that an amount of excavate material (21) is excavated from the marking (20). When a component such as a bearing (12) is positioned upon the bur tube (10), a portion of the excavate material (21) is physically impinged between the two components (10, 12) filling any spaces or gaps therebetween.
