Salt of a 1,3,5-triazine compound with polyphosphoric acid with a virtually linear structure, with the number average degree of condensation n being higher than 20, the content of the 1,3,5-triazine compound being higher than 1. The single electric motor is a non-line frequency electric motor. Also disclosed are newly found mutations in KVLQT1 which result in long QT syndrome. The adaptive canceller removes a portion of the undesired component in the first signal that is correlated with the undesired component in the second signal and provides an intermediate signal. Telescoping casing sections and bits are disclosed.
