    摘要: Process and apparatus for enhancing the erosive intensity of a high velocity liquid jet when the jet is impacted against a surface for cutting, cleaning, drilling or otherwise acting on the surface. A preferred method comprises the steps of forming a high velocity liquid jet, oscillating the velocity of the jet at a preferred Strouhal number, and impinging the pulsed jet against a solid surface to be eroded. Typically the liquid jet is pulsed by oscillating the velocity of the jet mechanically or by hydrodynamic and acoustic interactions. The invention may be applied to enhance cavitation erosion in a cavitating liquid jet, or to modulate the velocity of a liquid jet exiting in a gas, causing it to form into discrete slugs, thereby producing an intermittent percussive effect.

    摘要: A method for increasing the cross-flow microfiltration fluxes of waste waters containing suspended solids and/or emulsified oil through microporous thermoplastic tubes by including therein a calcium compound selected from Ca(OH).sub.2 or CaSO.sub.4. The calcium compound is present in the waste waters in an amount ranging from above the solubility limit of the compound to about forty (40) percent by weight of the waste waters. The Ca(OH).sub.2 can be added directly to the waste water. The CaSO.sub.4 can be included by reacting H.sub.2 SO.sub.4 and Ca(OH).sub.2 in the waste waters to form CaSO.sub.4 in situ. Alternatively, wet CaSO.sub.4 can be formed by reacting H.sub.2 SO.sub.4 with Ca(OH).sub.2 outside the water and then added to to the waste waters in the required amount.

    摘要: An improved rotational buoyant mass for wave energy conversion apparatus is disclosed. The rotational buoyant mass comprises at least one pair of helical volumes mounted for rotation about a common axis. The helical volumes are rotationally displaced with respect to one another about the common axis. The improved rotational buoyant mass may include multiple pairs of helices, the helices of respective pairs being displaced with respect to one another.
