Patent number: 7717984Abstract: An electrostatic precipitator unit used for the removal of coolant liquid and particles generated by a machine tool includes an electrostatic precipitator cell. The electrostatic precipitator cell includes power and collector ground fins and an ionizer grid positioned below the fins. The lower edges of the power fins are spaced above the collector ground fins to prevent contact of the liquid on the ground fins with the power fins. An electrical contact assembly for supplying electrical current to the ionizer grid and power fins is electrically isolated from all ground contacts by dielectric standoffs which define an insulating air gap. The likelihood of liquid tracking to ground is therefore eliminated.Type: GrantFiled: February 11, 2008Date of Patent: May 18, 2010Inventor: Mark Michael Schreiber

Patent number: 4066458Abstract: Exposure images may be synthesized on a radiation responsive surface by causing effective relative motion between a mask and the surface. The mask contains at least two distinct exposure areas, each having a plurality of apertures arranged in different patterns from which at least two different images can be simultaneously synthesized. Radiation is directed through the plurality of apertures in a mask during a given period to expose a plurality of similarly shaped areas on a surface. During a second period electrons are similarly directed through the same mask which has been effectively displaced and a second plurality of contiguous areas are exposed. During third and fourth succeeding periods, third and fourth pluralities of contiguous areas are exposed. Thus, the image in each exposure area is synthesized from a plurality of contiguous four step exposure images which makes it possible to eliminate the "stencil problem" and permit exposure of areas whose length is very much greater than their width.Type: GrantFiled: May 8, 1975Date of Patent: January 3, 1978Assignee: International Business Machines CorporationInventor: Paul E.

Patent number: 3992206Abstract: Lenticules of predetermined optical power and size are formed photographically in the emulsion of a photographic film. An emulsion is exposed to a target having a profile mathematically related to the cross sections desired in the lenticules to be formed. Exposure can be to a cyclically uniform target through a cylindrical lens, by scanning the cyclical target across the emulsion, or by scanning a single profile across the film emulsion in a raster pattern. Upon processing the emulsion in a prescribed manner, a phase image comprising contiguous cylindrical lenticules having cross sections which are predetermined in accordance with the target profile is formed in the emulsion. In a second embodiment, lenticules in an array or matrix having predetermined profiles are produced by exposing two emulsions to a target as above described and processing both emulsions to density images. The density image carrying processed emulsions are then superimposed, the density images formed thereon being orthogonally oriented.Type: GrantFiled: November 15, 1974Date of Patent: November 16, 1976Assignee: Eastman Kodak CompanyInventor: Robert L.
