The particles are readily formed using conventional crushing techniques from largerblocks of dry ice and then screening the resulting dry ice particles for size. (ii) To obtain the useful component. No damage was done to the joint or the tube. The mixture was loaded into a cylindrical gun about 20 inches long and with a 2% inch diameter. The method of claim 1 wherein as an additional step the dry ice particles before spraying are subjected to screening so that the particles have a diameter of less than the distance between the annular rings. The method of claim 1 wherein the wood is a softwood. A filler plug was provided at the breech of the gun and the gun was connected through the filler plug to a high pressure nitrogen tank (1,500 psi). Air from a compressor l5 driven through the orifice l4 aspirated the dry ice particles 10 from a container 16 and then the air passing through the discharge opening 13 accelerated the particles 10 through the discharge opening 13. This was accomplished by using high pressure bottled nitrogen to pressurize the mixture to about 800 psi and it satisfactorily deflashed the treated articles such as a nylon part with a mold flash. It was found that the soft portion 18 between the annular rings 19 was effectively removed to provide a weathered appearance. A method for the removal of unwanted portions of an article such as membranes, burrs and flashing utilizing solid particles of dry ice (carbon dioxide at a temperature colder than about -56*C) which are impacted against the unwanted portions is described.

If you want to use this method in an area where you have a large quantity of chemicals to remove from the water, it’s best to get a professional to set up the filter. EXAMPLE IV The procedure of Example I was repeated with a thin aluminum sheet having depressions about every oneeighth inch to remove a surface aluminum oxide which was tenaceously adhered to the surface. A related invention is disclosed in our copending application Ser. In addition, the dry ice particles cool the im-  References cued pacted area and with thermoplastic and elastic materi- UNITED STATES TENTS als thereby embrittles thin sections of flashing and burrs and the like making them more easily removable gopphn i by the impact f the dry ice particles. Top Answer. Reply Conversely, if treatment is to be avoided, the particles should be larger than the passages or impact otherwise restricted such as by mask means with openings to softer sections of an underlying article. 5 ways to get rid of unwanted particles in your water.

The dry ice particles are easily and economically removed by sublimation. 8, The method of claim 1 wherein the step of spraying is accomplished by driving a gas stream such that it aspirates the dry ice particles into the gas stream directed towards the wood surface for impact. 2013-10-30 08:43:59 2013-10-30 08:43:59. Dry ice particles no larger than three-sixteenths inch in diameter were aspirated from the container, with boiling liquid nitrogen (about minus 295F) driven through the orifice and nozzle. The filter traps solid particles, and the size of its pores or holes determines which particles pass through. When using this method, it’s important to keep an eye on the filter as algae and other microscopic life forms can begin to grow on it. This doesn't happen if you remove the provisioned app while Windows is offline. Tattoo removal is a procedure done to try to remove an unwanted tattoo. The dry ice particles additionally function to embrittle thin unwanted portions present as part of the impacted portions of the article. SPECIFIC DESCRIPTION The following are non-limiting specific examples of the method of the present invention. Offline SantaClawz69. Wiki User Answered . Various plastic parts were also deburred, the only limitation being that the ethanol does not significantly dissolve the plastic. The pages appear to be providing accurate, safe information. 2 schematically illustrates the preferred apparatus for spraying dry ice particles on the surface of an article to remove unwanted portions. Non-aqueous diluents can be used with the dry ice so long as they are not a solvent for, or a reactant with, the. The method of claim 11 including the additional step before spraying of covering the harder sections on the surface with masking means with openings to softer sections of an underlying surface. The sheet was completely reticulated and the remaining cell struts were firm and intact. Occasionally, a program may not be uninstalled completely and a reference to the program may remain in the Currently installed programs dialog box. In some instances it may be desirable to .use a heated gas stream or a vacuum for forced sublimation or alternatively to allow the article to dry by warming to ambient conditions. Even if you don’t live or work near one of these areas, it’s always a good idea to test the quality of the water you’re drinking. 1 and 2 ice particles were reduced to a particle size passing through a 16 mesh screen. Thus where articles have internal passages requiring treatment, the particles should easily enter such passages. The method for the removal of unwanted portions of an article which are relatively more susceptible to removal with sprayed high velocity particles which comprises: spraying the article including the unwanted portions with a high velocity spray of dry ice particles maintained under substantially anhydrous conditions until the unwanted portions are removed. The objects of the present invention are accomplished by the method for the removal of unwanted portions of an article which comprises: impacting the unwanted portions with dry ice particles maintained under substantially anhydrous conditions so as to remove the unwanted portions. Various methods for removing the dry ice particles are well known to those skilled in the art. git diff commit-id1 commit-id2 --stat If you want to know the lines added/changed/deleted by each commit, you could use. 0 1 2.
