In 1896 a hollow bowl separator was again placed upon 

 the market, this time b\- the Sharpies Company. This 

 separator had a long, narrow, suspended bowl, revolving 

 about 24,000 times per minute, in which the efficiency of 

 skimming was greater than that in the old hollow bowl 

 style of separators.

In 1902 this company introduced another separator 

 with a bowl of about the same construction but tilled 

 with a core made up of numerous sections which allowed 

 the speed to be reduced to 14,000 revolutions per min- 

 ute. This is a turbine separator a cut of which is shown 

 in Fig. 19. 



Numerous other power separators have been in use for 

 many years, chief among which may be mentioned the 

 United States and Reid.
