Dual stage actuated suspension having adhesive overflow control channels
ActiveUS9311938B1Shorten stroke lengthRepeatably controlledElectrical connection between head and armRecord information storageEpoxyDual stage
A dual stage actuated suspension has microactuators that are adhered to the suspension by adhesive such as epoxy. The epoxy is contained within an adhesive containment vessel defined by walls of an insulating material such as polyimide. Adhesive overflow channels are formed within the polyimide to receive and channel any excess epoxy that overflows over the polyimide wall. The channels may have increasing width to help draw the excess epoxy toward a centrally located reservoir.

Cross-Jack Counterbalance System
InactiveUS20110314959A1Reduce energy consumptionExtended component lifeControlling membersControlled membersReciprocating pumpPre-existing
The device is a counterbalance system and method to reduce the work of conventionally balanced, reciprocating cantilevered beam pumping units, and comprises a pair of transversely oriented support mounts attached to the cantilevered beam or walking beam of a pre-existing reciprocating pumping unit, attaching on either side of the pivoting-fulcrum, mounting point of the cantilevered walking beam. These transverse mounting points terminate individually on either side of said walking beam in channel-like saddles that support independent, parallel beams, which in turn cantilever themselves in tandem with said walking beam of the pumping unit; moreover, the position of the parallel beams by virtue of the transverse mounts creates a new center of gravity corresponding to the center of the pivoting mounting point of the walking beam, eliminating counter-productive torque forces on the walking beam as it tilts from horizontal.

The current signal (7) is measured by a current monitor (60) and a fast Fourier Transform value is produced. The FFT of the current signal (7) has been found to be directly related to the stability of operation of the Stirling engine. As harmonic peaks in the FFT increase, this indicates that the stroke length of the piston is approaching or exceeding a safe maximum. Correction action, such as a reduction in heat to the Stirling engine, can be taken in consequence. A variety of stroke length detectors (110) are also disclosed, for use in combination with, or separately from, the FFT analysis of the current signal (7). Optical and mechanical switches and analogue sensors are disclosed, along with an accelerometer mounted upon the casing of the Stirling engine.
