A GOOD SUBSTITUTE FOR THE ASPIRATOR BULB 

 ON THE CA STORAGE GAS ANALYZER 



Hamilton Lincoln aC the Brookfleld Orchards has cone up with what appears to 

 be an excellent substitute for the aspirator bulb on the gas analyzer. In place 

 of the bulb he has Installed an automobile fuel pump with a simple on-and-off 

 switch connected to a 6 or 12 volt battery. The rubber connection from the CA 

 rooQ Is merely attached to the Intake side of the fuel pump and the outgo side Is 

 attached to the analyzer. 



With this apparatus there Is a continuous gas flow from the CA room to the 

 analyzer and no more problems with leaky aspirator bulbs. This set-up, also, 

 eliminates the necessity of placing one's finger over the open-end of the main 

 stop-cock which Is essential each time an aspirator bulb Is released.
