These pendulum models comprise the downward pendulum [5], horizontal pendulum [6], inverted pendulum [7], spherical pendulum [8], the flexible pendulum [9, 10], the pendulum excited by an RLC circuit based on nonlinear shaker [11], and rotating pendulum [12].
It operated like a horizontal pendulum, but, like all the wonderful creations of a Black Country shed, the world's first seismograph was made from whatever was lying around.
The horizontal Pendulum omega loop is inverted, which will allow bodily movement of both the roots and crowns of the maxillary molars.
The aiming point of a horizontal pendulum is at the same elevation as the pivot.
This was, essentially, a horizontal pendulum, one end of which was fixed in bedrock.
* This observation interval is also necessary because of lack of seasonality and periodicity of occurrence of very strong non-tidal signals in time series from water-tubes and horizontal pendulum tiltmeters;
The main advantages of a WT tiltmeter with free water surface over other tiltmeter types include its stable sensitivity and a high and stable resolution of measurements (over two orders of magnitude higher than from a horizontal pendulum), its precise determination and stability of measurement azimuth, a lack of instrumental drift (which occurs hen a differential method is applied), a wide band of registered signals and the instrument's extensive groundwork with a measurement space of close to a hundred metres (Bower, 1973; Kaczorowski, 2006).

Long-term clinometric observations carried out with quartz horizontal pendulums provided numerous examples of rapid events of pendulums' equilibrium changes which lasted several days (Fig.
from the beginning of activation of quartz horizontal pendulums, irregular instability of their equilibrium which indicate effects of tiltings of foundation were registered.
During thirty years of work we irregularly observed seasons of unstable work of horizontal pendulums. Almost every year there happened several weeks long series when pendulums changed their azimuths of measurements (Chojnicki, 1981 and 1987).
