FROM THE PRACTICAL VIEWPOINT 



objection, in part at least, by providing a series 

 of tanks shown in Fig. 19. The five tanks shown 

 in line No. 1, 2, 3, 4, 5 are used for containing 

 the cases of filled bottles which are to be heated. 

 These are lowered into the tanks by suitable de- 

 vices. The other three tanks behind the pas- 

 teurizing tanks contain the water to be used in the 

 process. One, A, contains hot water, which is 

 kept at a constant temperature by means of a 

 thermostat. From this tank the water is circu- 

 lated by means of a pump through the tank, which 

 at the time contains the bottles which are being 

 heated and held. 



A second tank, C, contains cold water, which is 

 kept cold either by ice or by a brine coil. This 

 water is circulated by a pump through the pas- 

 teurizing tank, in which at the time are contained 

 the bottles which were being cooled. 



The third tank, C, is called a tempering tank. 

 The water in this is used for regenerative pur- 

 poses, in the following manner: After a tank full 

 of bottles has been heated and held for the de- 

 sired length of time, the hot water is all returned 

 to the heating tank, rendering the bottle tank 

 empty of water. Cool water from the tempering
