DEFINITION

Classification: 174/15.1

With cooling or fluid feeding, circulating or distributing:

(under subclass 8) Subject matter combined with means for feeding, circulating or distributing a fluid or with means for cooling either the fluid or the apparatus.

(1) Note. See Lines With Other Classes, above, section 1., for the lines between this subclass, other subclasses in this class, and elsewhere for housings and envelopes for electrical devices.
