Abstract: Abstract of the Disclosure This invention relates to an electromagnetic switching relay, which is adaptable to both monostable and bistable operation.  It is known to provide a relay having a coil form around which an excitation coil is wound.  The coil form has a central aperture containing a flat, centrally pivoted ferromagnetic armature having its limbs movable between contact shoes at each end of the coil form.  Ferromagnetic inlay elements are also provided at the ends of the coil form, and an external magnetic yoke is provided around the entire structure.  Thus, by passing a current through the coil, the armature aligns itself in bridging contact with diametrically opposed contact shoes, thus adopting a desired switch position.  The structure described suffers from the disadvantages that for bistable operation its construction is substantially different from that required for monostable operation, the armature is not fixed in its longi-tudinal direction and can therefore be jarred out of position by externally applied shocks, and there is no provision for adjustment or variation of the switching sensitivity.  The present invention avoids these problems by locating the armature in its longitudinal direction by use of enclosed bearings having convex bearing surfaces   The ferromagnetic inlay elements are interchangeable with soft metal elements to provide flexibility between monostable and bistable operation and the inlay elements are magnetically partially insulated from the contact shoes to provide stray lines of force whereby the sensitivity may be adjusted.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention is a device which provides for separa-tion of contaminants from a relatively high velocity axially flowing stream of gas.  The invention provides a first stage wherein the gas stream is decelerated and the contaminants particles are caused to separate from the air stream by impinging a first surface.  The impact results in the particles to acquire a radial velocity section and by virtue of the particles momentum the contaminants are forced to the outer layer of the air stream.          The second stage of separation provides for further magnifica-tion of the radial velocity vector of the particle contaminants and also induce a slight tangential component to the contaminant particle velocity.  By impacting the contaminants against a blade mounted within the gas stream, the contaminant particles, as a result of this impact, acquire a slight swirl or circular motion which causes the heavier contaminant particles to be further separated from the air stream and become more localized.  In the next stage of the cleaning device, the gas stream is rapidly accelerated by decreasing the area through which the gas stream must travel.  This increase in velocity of the gas stream increas-es the separation for the smaller contaminant particles until a final separation stage is attained.  In this final stage, the velocity of the gas stream is significantly decreased without inducing flow separation.  The air velocity is totally slowed down and the particles continue along the periphery of the clean-ing device into a discharge channel, while relatively clean gas continues in its axial flow.

Abstract: Abstract of the Disclosure A method of treating a subterranean formation which has undergone an in situ leaching operation which utilized an ammonium solution as the lixiviant.  In such a leach operation, ammonium ions will exchange into the clay in the formation and will present a threat of contamination to any ground waters that may be present in the formation. The present method involves flushing the formation with a halogenated restoration fluid, e.g., chlorinated water having a halogen therein which reacts with ammonia within the formation to decompose the ammonia to nitrogen.  The halogenated restoration fluid can be continuously injected or it can be injected as a slug followed by a relatively halogen-free solution to complete the operation.  The ammonia concentration of the produced fluids is monitored and when it drops below a desired value, the method is complete.
