.~ With motion or vibration damping means (e.g., dashpots)
DEFINITION
Classification: 338/98
(under subclass 68) Subject matter including structure associated with the mechanically adjustable portion of the resistor for retarding the adjustment of the resistor over at least a portion of the adjustment range, or for eliminating or reducing vibration.
(1) Note. Examples of motion damping means are fans, speed responsive brakes, or damping liquids. The subject matter of this subclass includes structure for slowing down the desired mechanical adjustments of the resistor as to prevent hunting of the resistor. Structure for eliminating or offsetting or otherwise controlling the effect of vibration in photo-conductive resistors is in subclass 16 above, while subclasses 315+ provides for resistors generally with anti-vibration supports.

43+, for resistors responsive to a gravity stabilized or inertia device.
80+, for mechanically variable resistors with a liquid element. 171, for variable resistors with a contact slidable on the resistance element, the contact having plural element engaging portions, which may reduce the effect of vibration.
315+, for resistors generally with anti-vibration supports. See also (1) Note above.
