Abstract: A polymer complex is disclosed which is the reaction product of one or more polymers having a terminal or pendant hydroxyl group, or a terminal or pendent carboxyl group, or combinations thereof, with at least one metal complex and one alkyl phosphate. This polymer complex acts as an adhesion promotion agent as well as a viscosity stabilizer when formulated in a printing ink or coating.

Abstract: The present disclosure provides liquid surge suppressors and methods of manufacturing such surge suppressors. In one exemplary implementation of the invention, a surge suppressor includes a plurality of flexible longitudinal members, each of which is joined to the other longitudinal members at a first junction and at a second junction spaced from the first junction along a central axis. A generally planar medial disk may lie in a transverse plane substantially perpendicular to the central axis and having a generally circular central orifice. The medial disk being joined to a portion of each of the longitudinal members intermediate the first and second junctions and defining a fixed relationship between the longitudinal members.

Abstract: Vibration in the helicopter fuselage produced through the helicopter rotor at a frequency of one for each rotation of the rotor (commonly identified in the art as a one-per-rev vibration) is controlled by applying a correction signal to the primary cyclic control system of the rotor assembly. To generate the correction signal, a transducer responds to the one-per-rev vibrations to generate a signal coupled to circuitry for generating a vibration related signal dependent upon the amplitude and phase of the one-per-rev vibrations. The vibration related signal is applied to a sample and store network wherein it is demodulated by a reference signal related to the rotational speed of the helicopter to establish a control voltage which varies at a rate in dependence upon variation in the maximum amplitude of the one-per-rev vibrations. This control voltage is integrated and modulated by the reference signal thereby resulting in the correction signal for application to the primary cyclic control system.

Abstract: The method of balancing a rotor having multiple blades and defining an axis of rotation, and wherein structure proximate the rotor is subject to vibratory motion due to dynamic unbalance of the rotating rotor and an out-of-track condition of the rotor blades, the method employing two vibration pickups, the method including:A. operating the pickups to produce vibratory signals corresponding to up and down vibratory motion of the structure at port and starboard sides of said axis,B. combining said signals to produce a resultant oscillatory output signal characteristic of rotor vibratory motion due substantially to only one of said conditions,C. using said resultant output signal to alleviate said one condition.
