Generating sets of tailored laser pulses

In a master oscillator power amplifier, a driver (208) of a diode laser (202) is specially controlled to generate a set of two or more injection laser pulses that are injected into a power amplifier (204) operated in an unsaturated state to generate a set (50) of laser pulses (52) that replicate the temporal power profile of the injection laser pulses to remove a conductive link (22) and / or its overlying passivation layer (44) in a memory or other IC chip. Each set (50) includes at least one specially tailored pulse (52) and / or two or more pulses (50) having different temporal power profiles. The duration of the set (50) is short enough to be treated as a single “pulse” by conventional positioning systems (380) to perform on-the-fly link removal without stopping.

Modular multi-stage fusing system

A multi-stage fusing system for fixing toner images to copy substrates of various weights has a primary fuser and a secondary fuser in series with the primary fuser. Various weights of print substrates may have toner images fixed thereon by the primary fuser. The various print substrates are then transmitted to the secondary fuser or directly to a finishing area. The secondary fuser is designed specifically for heavier weight substrates and a bypass paper path is provided for allowing lighter weight substrates to bypass the secondary fuser.

Process and apparatus for separating hydrocarbons from produced water

A process for removing hydrocarbons such as oil from produced water entrains high concentrations of very small gas bubbles within produced water inside a vertically-oriented primary separation tank by means of aerators immersed in the water inside the tank. Oil droplets coat the gas bubbles which form a buoyant oil-rich froth phase overlying a gas-rich liquid phase. The froth phase flows out through a discharge port in a preferably conical upper section of the primary tank, for disposal or recovery of oil as appropriate. Solid contaminants not borne by the froth phase may be intermittently settled out of the liquid phase and removed for treatment or disposal through a discharge port in a preferably conical lower section of the primary tank. Clean processed water is drawn a medial region of the primary tank for re-use as appropriate. In a preferred embodiment, the froth phase passes into a secondary separation tank for further separation of contaminants by means of gravity and / or supplemental aeration.
