Sample collector and components thereof

Abstract

The bottle rack for the sample collector is made by injection molding two halves of the rack each of which has a matching surface and a bottle positioning surface. The matching surfaces are fastened together by placing the matching surfaces together back to back whereby locating members are spaced apart a sufficient. To warm a compressor to a starting temperature during cold weather, the ambient temperature is measured and when the ambient temperature is lower than a preset temperature and the compressor is not running, current is applied to the motor windings to warm the compressor.

1 . A method of making a bottle rack, comprising the steps of:
 forming a first half of the rack;   the first half of the rack including a matching surface and a bottle positioning surface, with the distance between the bottle positioning surface and the matching surface being one half of a stability design distance;   forming a second identical rack half;   placing matching surfaces together back to back whereby locating members are spaced a stability design apart for holding bottles.   
   
   
       2 . A method in accordance with  claim 1  in which the step of forming a first half of the rack includes the substeps of forming a bottle half by injection molding in a mold that forms a rectangular base as with the matching surface on it with an opening in the center and a cylindrical ring of the bottle positioning surface surrounding the opening in the center, whereby bottles are positioned in bottle positioning members to extend the opening in the center of the rectangular base with a surface against two aligned bottle positioning members separated by a stability design distance. 
   
   
       3 . A method in accordance with  claim 2  in which the bottle positioning surface is mounted to a cylindrical supporting and positioning wall. 
   
   
       4 . A bottle rack comprising a central member adapted to be mounted horizontally;
 said central member having two identical members positioned back to back and bottle holding and positioning surfaces extending outwardly from the two identical members; and   a bottle rack bottom positioned to close off one of the extending cylindrical members, whereby bottles may rest on the bottom and extend upwardly to opposite cylindrical wall.   
   
   
       5 . The bottle rack of  claim 4  in which two symmetrical members are held together by screws, whereby they may be molded separately in a single cavity mold. 
   
   
       6 . The bottle rack of  claim 4  in which the cylindrical members have cylindrical walls, the cylindrical walls each having an opening in the center to which the bottles extend. 
   
   
       7 . The bottle rack of  claim 4  in which at least two bottle positioners are mounted to the cylindrical wall to position the bottles against tangentially slanting.
