Abstract:
The method according to the invention for electrostatic coating of an electrically conducting workpiece with coating powder includes the following steps. The workpiece is earthed. Then an electrode has a negatives potential applied to it compared to that of the workpiece and a counter-electrode has a positive potential applied to it compared to that of the workpiece. The potential in the area of the workpiece in which the workpiece is to be coated is set to zero, by means of a control unit. Afterwards the workpiece is sprayed with coating powder in the area to be coated using a powder spray gun.

Abstract:
A liner and method of application for use on a metal surface to protect metal structures such as cooling towers, evaporative condensers, and other liquid containing vessels such as tanks from corrosion, leaks, and wear. The liner is an inexpensive apparatus and process comprising a coated metal having a second sealing and bonding layer and a third protective sealing layer. The liner method comprises applying an organic bonding layer onto the galvanized substrate, and applying an elastomeric barrier coating to the bonding layer. The barrier coating material is applied to preseal the seams between adjoining panels assembled to form the basin. The barrier coating is applied to the entire inside of the basin to form a homogenous barrier coating extending out of the basin. The liner edge is isolated from the basin by extending the liner to a point between the basin and an upper section. The liner comprises galvanizing layer, a bonding layer on the galvanized metal, and an elastomeric third layer on the bonding layer. The liner further comprises preseals at the seams, corner molds and link holes in the substrate to attach and protect the liners integrity.

Abstract:
A method for establishing a calibrating standard for wafer inspection includes depositing solid ionized particles of a known size range with an aerosol onto a wafer. The method also includes depositing particles onto a wafer in a deposition chamber by using an aerosol stream and the solid particles suspended in a gas; ionizing the aerosol stream with a negative or positive charge polarity or both by passing the aerosol stream through a non-radioactive ionizer to produce charged particles and supplying such aerosol stream to the deposition chamber. An apparatus for producing charged particles includes an atomizer and a non-radioactive ionizer in fluid communication with each other. The apparatus may also include an electrospray droplet generator for producing an aerosol with dry-solid particles and an ionizer that ionizes the molecules of the gas. The apparatus may also include a generator for generating an aerosol with particles suspended in the gas with a non-radioactive ionizer that ionizes the gas in the aerosol causing the aerosol particles to be charged. The apparatus may further include an electrostatic classifier for classifying the charged particles to a selected size range.
