Method and apparatus for waste evacuation

Abstract

A method and apparatus for waste evacuation using an extendible and retractable hose for transferring the waste have been described.

1 . An apparatus comprising: 
 a flexible hose having an input and an output, said flexible hose capable of extending and retracting in length and maintaining a fixed length without external forces being applied;    a source of material to be transferred through said flexible hose wherein said source of material to be transferred is in communication with said flexible hose input; and    a sheath through which said flexible hose may extend and retract.    
   
   
       2 . The apparatus of  claim 1  further comprising a nozzle having an input and an output, said nozzle input in communication with said flexible hose output.  
   
   
       3 . The apparatus of  claim 1  further comprising an extend/retract module in gas communication with said flexible hose.  
   
   
       4 . The apparatus of  claim 3  further comprising: 
 a handheld remote control; and    a receiver capable of responding to a signal from said handheld remote control.    
   
   
       5 . The apparatus of  claim 4  further comprising a nozzle box.  
   
   
       6 . A method comprising: 
 activating a handheld remote control;    receiving a signal from said handheld remote control;    controlling an extend/retract module based on said received signal from said handheld remote control; and    based on said received signal from said handheld remote control either: 
 extending a flexible hose; or  
 retracting a flexible hose.  
   
   
   
       7 . The method of  claim 6  wherein said extending said flexible hose is accomplished by supplying a positive gas pressure with respect to local atmospheric pressure to a inside of said flexible hose.  
   
   
       8 . The method of  claim 6  wherein said retracting said flexible hose is accomplished by supplying a negative gas pressure with respect to local atmospheric pressure to a inside of said flexible hose.  
   
   
       9 . An apparatus comprising: 
 means for receiving and responding to a handheld remote control device;    means for activating an extend/retract module in communication with an extendible hose; and    means for transferring material through said extendible hose.    
   
   
       10 . The apparatus of  claim 9  further comprising charging a fee for said transferring material through said extendible hose.
