Abstract

A new automatable cleaning apparatus which makes use of a method of very thoroughly and quickly cleaning a gauze electrode used in chemical analyses is given. The method generates very little waste solution, and this is very important in analyzing radioactive materials, especially in aqueous solutions. The cleaning apparatus can be used in a larger, fully automated controlled potential coulometric apparatus. About 99.98% of a 5 mg. plutonium sample was removed in less than 3 minutes, using only about 60 ml. of rinse solution and two main rinse steps.

Methods and apparatus for cleaning objects in a chamber of an optical instrument by generating reactive ions using photon radiation

Patent Klebanoff, Leonard E.; Delgado, Gildardo R.; Hollenshead, Jeromy T.; ...

An optical instrument, including a chamber, an object exposed to an interior of the chamber, a source of low-pressure gas, the gas comprising at least one of low-pressure molecular hydrogen gas, low-pressure molecular oxygen and a low-pressure noble gas, the source of low pressure gas being fluidly coupled to the chamber, a low voltage source electrically coupled between the object and a remaining portion of the instrument that is exposed to the interior of the chamber so as to maintain the object at a low voltage relative to the remaining portion, and an EUV/VUV light source adapted to direct EUV/VUVmore » « less

Method and apparatus for inducing turbulent flow of a processing chamber cleaning gas

Patent Chung, Hua; Dong, Xizi; Maung, Kyawwin Jason; ...

Embodiments of the invention generally relate to apparatus and methods for cleaning chamber components using a cleaning plate. The cleaning plate is adapted to be positioned on a substrate support during a cleaning process, and includes a plurality of turbulence-inducing structures. The turbulence-inducing structures induce a turbulent flow of cleaning gas while the cleaning plate is rotated during a cleaning process. The cleaning plate increases the retention time of the cleaning gas near the showerhead during cleaning. Additionally, the cleaning plate reduces concentration gradients within the cleaning plate to provide a more effective clean. The method includes positioning a cleaningmore » « less

Method and apparatus for the clean replacement of contaminated HEPA filters

Patent Wiedmeyer, Stanley G.; Frigo, Arthur A.; Preuss, Daniel; ...

A method and apparatus are provided for the replacement of contaminated HEPA filters without contamination of the surrounding environment. A filter housing is generally cylindrical and defines a filter receiving cavity. The filter housing having a filter receiving end and a filter removing end. An active HEPA filter is received within the filter housing cavity and is located near the filter removing end. A backup HEPA filter is received within the filter housing cavity and is located near the filter receiving end. A change-out bag is received within the filter housing cavity and is located adjacent to the filter removingmore » « less

Method and apparatus for a self-cleaning filter

Patent Diebold, James P [Lakewood, CO]; Lilley, Arthur [Finleyville, PA]; Browne, III, Kingsbury (Golden, CO); ...

A method and apparatus for removing fine particulate matter from a fluid stream without interrupting the overall process or flow. The flowing fluid inflates and expands the flexible filter, and particulate is deposited on the filter media while clean fluid is permitted to pass through the filter. This filter is cleaned when the fluid flow is stopped, the filter collapses, and a force is applied to distort the flexible filter media to dislodge the built-up filter cake. The dislodged filter cake falls to a location that allows undisrupted flow of the fluid after flow is restored. The shed particulate ismore » « less
