Disclosed is a filtration enhancement apparatus and an associated method. The apparatus includes a number of electromagnetic grids that are placed in series. The first grid conditions ambient particles to generate particles with both a positive and a negative charge. These charged particles are then delivered to a second and third grid wherein a low, medium, and/or high frequency alternating current is employed to force the positive and negative charged particles to collide and conglomerate with one another. The conglomerated particles are then sent into the ambient environment for subsequent filtration.

Apparatus and method for enhancing filtration

The present invention provides a process for rendering acrylic based negative photoresists resistant to hot alkaline permanganate etchant and the iron chloride etchant and for improving the adhesion of the photoresist to the substrate, yet does not require halogenated reagents to develop or strip the photoresist. It has been discovered that the degradation of acrylic based negative photoresists by the permanganate etchant may be overcome by exposing an imaged acrylic based negative photoresist to select wavelengths of actinic radiation either ultraviolet light that is rich in deep UV, about 254 nm wavelength; or infrared radiation from about 2.4 to about 8 microns. Where UV radiation is used, the photoresist is then baked to reduce undercutting of the photoresist. Thereafter, the photoresist is stripped using nonhalocarbon solvents.

Fingernail cleaning apparatus in which a disc-shaped rotary brush is utilized in combination with cleaning liquid to obtain effective cleaning action for the fingernails. The rotary brush is mounted rotatably inside a housing, and a mouth of the housing is closed by a guide assembly which forms entrances for only the fingers to be received in the housing. Liquid is received in the housing. The guide assembly includes sealing structure for sealing around the fingers to prevent escape of liquid. The rotary brush is driven by a motor.
