The present invention provides a human engineered power and control system for artificial hearts or assist devices configured for ease of use, ruggedness, and high reliability. Battery powered systems of the prior art have required multiple cables and connectors that are subject to failure due to damage or wear. In the present invention, direct connection of the batteries to the control system eliminates multiple cables and connectors used with previous designs. A novel method of connecting batteries to the control system and exchanging batteries without interruption of power is provided in a compact user friendly configuration. The control system may provide periodic reductions in assist device flow to permit the natural ventricle to eject blood through the natural outflow valve, open the valve leaflets to prevent them from adhering together, and achieve sufficient washout to prevent thrombosis. Using either software based control or software independent electronic circuitry, the flow pumped by the artificial heart is reduced for a long enough period of time to permit at least a few beats of the natural heart to generate sufficient pressure to open the outflow valve. In a control system embodiment in which the patient manually adjusts the pump speed to incremental settings for rest and exercise conditions, a pulsatile flow mode is disclosed which provides approximately the same flow at a given incremental setting as the pump produces when running in a constant speed mode at the same setting. As the patient learns which speed setting is best for daily activities, the patient may use the same setting with either a pulsatile or constant pump speed mode.

A modified and emulsified color asphalt is prepared from asphalt matrix, modifier (EVA, SBR, or SBS), emulsifier, stabilizer, surfactant, acid, alkali, adhesive, pigment and water.

The concentration of citrate complexing agent in an electroless cobalt or nickel plating bath is determined by titrating a sample of the electroless plating bath containing a small concentration of free fluoride ion with a standard lanthanum nitrate solution. During the titration, La<3+> ion first reacts preferentially with the citrate complexing agent and then with fluoride ion, which reduces the free fluoride ion concentration. The endpoint for the titration is indicated by a substantial decrease in the free fluoride ion concentration, which is detected via a fluoride ion specific electrode (ISE). The method can be used for analysis of other complexing agents.

Durable pumps for abrasives are provided. An example centrifugal pump stage for subsurface operation has a thrust washer located inside the circumference of an outboard clearance seal between an impeller shroud and the diffuser. Relocation of the thrust washer allows the clearance seal to protect the thrust washer from abrasives. A centrifugal action of an outboard seal lip effects a separation of the particles from the fluid nearest the gap of the outboard seal and drives the particles away from the gap of the outboard seal. When an abrasive particle in the leakage flow does clear the outboard seal, the particle is readily flushed across the thrust washer by the leakage flow to the central fluid inlet to prevent wear of the thrust washer. In an implementation, the inside diameter of the thrust washer is approximately flush with the bore of a central fluid inlet of the pump stage.
