Three solution application method for tattoo removal.

A method of removing reverberation from audio signals is disclosed. The method comprises spectro-temporally analyzing the first audio signal and the second audio signal to derive an energy function of time for a plurality of frequency bands. The method further comprises determining a delay stability between the energy function of time for the first audio signal and the second audio signal in each band, determining a gain function in each band based on the delay stability, adjusting the energy of...

To reduce damage to surrounding tissue while fragmenting some tissue such as for example not damaging the capsular wall while removing the lens during cataract removal surgery or not damaging artery or vein walls during bypass surgery while freeing the artery or vein to be transplanted, an incision is made for the insertion of surface--discriminating, rotating, fragmenting handpiece. The surface--discriminating fragmenting handpiece fragments and permits aspiration of the tissue without damaging...

Accurate, non-mechanical removal of the epithelium from essentially only the area of the cornea to be treated. In particular, an epithelium-ablative laser device irradiates the selected region of the epithelium with ablative laser energy, a spectroscopic system monitors the ablation and spectroscopically determines whether epithelium is being ablated, and a control system terminates the epithelium removal upon spectroscopic determination of a substantial absence of epithelium ablation.

A process for reducing the amount of down time or yield loss associated with a sulfur upset when using a sulfur-sensitive catalyst. The process comprises applying a metallic coat, cladding, plating or paint to a reactor system which comprises a base metal, so as to form an adherent metallic layer on the base metal and thereby produce a metal-coated reactor system; loading a sulfur-sensitive catalyst into the system; and, after a sulfur upset, using a process comprising sulfur stripping to remove...

A tool for removing a carburetor needle valve adjustment limiter cap has a handle with a set of jaws at one end for engaging the end cap and an actuator at the opposite end for applying force to the jaws to remove the end cap from the valve body. In a preferred form, the actuator has a slidable weight or mass that can be reciprocated along the handle to impact against a stop on the handle at an end opposite from the jaws. In another form, the actuator has a rod extending transversely through the...

Heavy elements such as Pb, Zn, Cd, Ni, Cu and Cr constitute health hazards and are sources for environmental pollution. These elements should therefore be removed from industrial effluents. Biomass of Cladosporium cladosporioides (Fresen.) de Vries. Acc. No. 285712 is readily produced by culture in either standard fungal medium or on media composed of food-industry wastes: whey and distillery slop. The thus produced fungal biomass efficiently removes heavy elements from liquid solutions. Removal...

A dust pre-precipitator centrally supports a plurality of filters with dry filter elements; raw gas flows down in the pre-precipitator and emerges from the bottom thereof in a dust bag, and a reversal of gas flow obtains as it flows through the dust bag and into the filters through the respective inlets thereof; clean gas is extracted from the top of the filters, and cleaning gas can be selectively fed to them from the top thereof; each of the filters contains a funnel shaped transition, and a d...

A chlorination system in which brine is converted to sodium hypochlorite by an electrolyser. Brine (1) fed to the electrolyser (3) is passed through a filter (2) which is capable of adsorbing bromine or hypobromous acid. Some of the sodium hypochlorite produced in an electrolyser (3) is fed back to a point in the brine feed upstream of the filter (2) such that any bromide in the brine is oxidized to bromine or hypobromous acid and therefore adsorbed by the filter (2).

Grasping an object, e.g., a calculus in the biliary tract, using a grasper, such as a basket, that can be opened and closed without mechanical advantage and also rotated about the device axis to make it easier to capture the object. The basket can then be closed further with mechanical advantage to crush the object.
