DEFINITION

Classification: 55/495

(under subclass 490) Apparatus comprising a separating media which is either of self-sustaining form, encased or form maintained, or of coherent sheet form (not loose and particulate), said separating media being either retained in a flow line or retained in a peripheral support.

(1) Note. A unit is considered to be any media of rigid form maintaining configuration which maintains its rigidity without a frame, or because of a frame. A media of cohesive sheet-like material is one that is flexible rather than self supporting and is unitary in the sense that it is coherent and has tensile strength. (Sheet-like as contrasted with a pad or mass of fibres and cohesive as contrasted with loose material).
