DEFINITION

Classification: 134/110

(under subclass 109) Apparatus in which the fluid purifying or separating means operates by filtering or straining contaminating solids therefrom.

(1) Note. Foraminous workholders, which permit the passage of fluids for, or the escape of fluids after, application to the work, are not included, even though disclosed or claimed as a filter or strainer. The fluid filter or strainer must be in addition to the work holder.

(2) Note. Foraminous structures through which fluids are delivered against the work in the form of a spray or plural jets are not considered to be filters or strainers. The filter or strainer must be in addition to such structure.
