Abstract: Case-185 ABSTRACT    In this invention sulfide compounds are added to mercury and precious metal-containing carbonaceous ore slurries prior to the  slurry being processed by a carbon-in-pulp system.   The sulfide compound inhibits the mercury from being adsorbed onto the activated carbon by reacting with the mercury to form mercuric sulfide and by inhibiting the dissolution of mercury from the ore.  The mercuric sulfide precipitate displays no activity toward the activated carbon.  The sulfiding procedure is performed with a sufficient amount of sulfide-providing compound to provide at least about 30 times the stoichiometric amount of sulfide ions required to react with the mercury in the ore slurry.

Title: Tamper-evident closure cap and container
Inventor: NOFER KARL H
IPC: B65D41/34
Filed: 1987-03-23
Granted: 1991-04-02
Abstract: ABSTRACT         A tamper-evident closure cap and corresponding container have projections on a skirt of the cap corresponding to projections on a neck of the container.  The skirt is connected to a remainder of the cap by a series of severable tabs.  The projections are shaped to override one another when the cap is turned onto said container but to interlock with one another when the cap is turned off said container.  When the projections interlock, the force exerted on the cap severs the tabs, thereby severing the skirt from the cap and providing evidence of tampering.  The cap and container are operable over a wide range of tolerances and the tabs can be very small when compared to previous caps and containers.

Abstract: ABSTRACT OF THE DISCLOSURE            A  saw blade,  for  a power saw having two such blades arranged adjacent and parallel to each other and reciproc-ating in opposite directions, comprises an elongate blade member  having  teeth  along  a  bottom edge.    The teeth comprise at least three types, a first type being at an outer surface of the blade member, a third type being at the inner surface, and the second type being therebetween. The first type are shaped to produce on the blade's bottom edge an outward force away from the inner surface while cutting a workpiece, and the second and third types are shaped to produce on the blade's bottom edge an inward force,  the resultant  force on the teeth while cutting urging the teeth in an inward direction away from the outer surface towards the inner surface.  When the power saw is operating with a pair of these blades, the blades are urged together at their teeth by the cutting action so effectively  eliminating  penetration  of  sawdust  and cuttings between the pair of blades.  Advantageously the saw blades can be very thin-walled, e.g. 1mm to 2mm thick.
