The circumferential vibration of a hollow quartz cylinder has been thoroughly studied. The empirical relation connecting the dimensions of the cylinder and the frequency of vibration has been formulated, and the temperature coefficients of the frequency determined. The temperature coefficient is practically zero for a wide range of temperature, when the ratio of the internal radius to the external radius of the cylinder approaches a value which is very close to 0.5.

Formulas are derived for the solution of the transient currents of resistance-terminated dissipative T-& π-type band-pass electric wave filters of the constant X type. Oscillagrams taken hy cathode ray oscillograph for d-c. & a-c. cases are found to agree with the calculated results. From these calculations, the following conclusions are derived: (1) No matter what the impressed frequencies are, the transient is ultimately of the lower cut-off frequency. (2) The receiving-end indicial admittance consists of transient terms symmetrical with respect to the mid-frequency term. (3) The transients die out faster in the filters of smaller number of sections. (4) With the same network constants, the transients die out faster in the t-type filters. (5) Filtering property only exists in the steady state. (6) The band width increases with the number of sections. This increase is greater in π-type filters, but the band width is greater in T-type filters.
