Abstract: Disclosed is an armature or matrix for a magnetic separator which is to be placed into a magnetic field, for separating paramagnetic components from a particular wet or dry feed, wherein the matrix has a number of low-corrosion or corrosion-free soft magnetic plates disposed parallel to each other and spaced from each other in a direction perpendicular to the magnetic field, nonmagnetic spacers are interposed between the plates, and nonmagnetic ties are used to tie the plates and the spacers together into the matrix.

Abstract: An apparatus for dispensing a measured amount of a spray-entrapped product, typically dispensed by a metered dose inhaler device, includes an elongated passageway having a mouthpiece portion and a main chamber portion. The metered dose inhaler is mounted between the mouthpiece and main chamber portions such that upon operation its spray is directed away from the mouthpiece. A two-position valve is provided to allow a first, low-level flow to be developed through the unit, followed by a higher flow rate as the metered dose inhaler unit is operated. This increased flow, passing through the device in the direction opposite to that of the MDI spray, contacts the spray plume to cause a high level of mixing and a decrease in spray particle size which results in an efficient draw of the spray medication into the lungs of the user.
