Abstract: The invention relates to an air filter having a primary air region and a secondary air region separated by a barrier. The primary air region contains a filter element for filtering out particles in the primary air. The secondary air region is designed to receive crankcase emissions sent from an engine's crankcase. Crankcase emissions are a result of gas escaping past the piston rings and into the crankcase due to high pressures in the cylinder during compression and combustion. To aid in removing these gasses from the crankcase, a venturi is enclosed within the housing to increase the negative pressure within the housing and in the secondary air region. This increase in negative pressure draws crankcase emissions out of the crankcase and thus reduces oil and crankcase gas bleeding from the crankcase.

Abstract: Embodiments of a new hand-held bird feeder are disclosed, permitting economical construction, the use of which feeder enables the bird feeding enthusiast actively to entice birds to feed, to feed birds in close proximity, and to relocate the site of feeding as necessary. The preferred embodiment discloses a cane with two ends, one of which is adapted for use as a handle, a receptacle for holding bird feed affixed to the end of the cane distal from the handle, and a perch affixed to the cane proximal to the receptacle.
