Abstract
Preferred nose cones 100 associatable with a tail spout 120 of a sand handler and a vacuum hose 130 of a vacuum system are described herein. A method for containing respirable and/or inhalable particles 140 created in an industrial process is also disclosed herein.
Claims18
A nose cone associatable with a tail spout of a sand handler and a vacuum hose of a vacuum system, said nose cone comprising:
- (a) a material sheet that has an upper edge, a lower edge, a first side edge, and a second side edge;
- (b) said first side edge of said material sheet at least partially overlapping said second side edge of said material sheet to form an overlap therebetween, at least part of said upper edge of said material sheet forming an open upper end of said nose cone, and at least part of said lower edge of said material sheet forming an open lower end of said nose cone;
- (c) a viewing window is formed between a lower portion of said first side edge of said material sheet and a lower portion of said second side edge of said material sheet;
- and
- (d) at least one attachment mechanism securing said material sheet at or near said overlap;
- (e) wherein said open upper end of said nose cone is associatable with said tail spout and said vacuum hose to contain respirable and/or inhalable particles created in an industrial process.
A nose cone associatable with a tail spout of a sand handler and a vacuum hose of a vacuum system, said nose cone comprising:
- (a) an at least semitransparent material sheet that has an upper edge, a lower edge, a first side edge, and a second side edge, said material sheet wrapped to form a cone;
- (b) said first side edge of said material sheet at least partially overlapping said second side edge of said material sheet to form an overlap therebetween, at least part of said upper edge of said material sheet forming an open upper end of said nose cone, and at least part of said lower edge of said material sheet forming an open lower end of said nose cone;
- (c) said open upper end having an upper diameter and said open lower end having a lower diameter, said upper diameter being smaller than said lower diameter;
- (d) a generally triangular viewing window is formed between a lower portion of said first side edge of said material sheet and a lower portion of said second side edge of said material sheet;
- and
- (e) at least one attachment mechanism securing said material sheet at or near said overlap;
- (f) wherein said open upper end of said nose cone is substantially sealable with said tail spout and said vacuum hose to contain respirable and/or inhalable particles created in an industrial process.
A method for containing respirable and/or inhalable particles created in an industrial process, said method comprising the steps of:
- (a) creating a nose cone using a material sheet having an upper edge, a lower edge, a first side edge, and a second side edge, creating said nose cone by wrapping said first side edge of said material sheet to at least partially overlap said second side edge of said material sheet to form an overlap therebetween, to form an open upper end of said nose cone from at least part of said upper edge of said material sheet, and to form an open lower end of said nose cone from at least part of said lower edge of said material sheet;
- (c) forming a viewing window between a lower portion of said first side edge of said material sheet and a lower portion of said second side edge of said material sheet;
- (d) securing said material sheet at or near said overlap using attachment mechanisms;
- and
- (e) securing said open upper end of said nose cone with a tail spout and a vacuum hose to contain respirable and/or inhalable particles created in an industrial process.
