Abstract: BALANCING MECHANISM FOR MANHOLE COVERS            ABSTRACT OF THE DISCLOSURE       A balancing mechanism for manhole covers uses two sets of conical disc springs, one stronger than the other, mounted on a common pull rod, to balance the cover as it moves from the open vertical position to the closed position.  This provides a progressive spring force curve that balances the manhole in any position between the closed position and the vertical position.     The balancing mechanism is also provided with an additional set of disc springs that absorb shock when the cover is opened rapidly.          The mechanism is preferably mounted on a nozzle protection ring, which allows the system to be installed on existing glass lined vessels without welding, drilling or similar operations which might damage the lining.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for recovering iron and nickel from a mixture comprising a nickel silicate, an iron sulfide and a flux.  In the process the minerals are heated under an excess of oxygen to produce iron, nickel and sulphur dio-xide.  The iron and nickel are recovered.  The sulphur dioxide may be used, for example, to produce sulphuric acid.        The process is, unlike the prior art, exothermic so that once the mixture is heated to a temperature of about 800°F the reaction becomes self-sustaining.  Furthermore, the excess heat produced may be used to dry the ore or for power generation.

Abstract: ABSTRACT Two indirectly mounted tapered roller bearings that are located between a spindle and a hub are set by first bringing one of the bearings into a condition of no end play and then measuring the distance between the cup of the second bearing and the end of the spindle.  A spacer is then selected and fitted between the end of the spindle and an end plate that is bolted against the spindle.  The end plate abuts against the back face of the cone for the second bearing, and the end plate position, which is con-trolled by the thickness of the spacer, determines the setting for the bearings.  The proper thickness for the spacer is determined by subtracting the measured dimension from a value derived from a table.
