Abstract: A guide means for individually adjusting each of the carrier belts of a multi-belt horizontal belt filter is disclosed. The guide means includes a plurality of support rollers, each having a rotatable roller segment which is held in rolling contact with a respective carrier belt. The remaining structure of the support roller is held out of contact with the remaining carrier belts. Each support roller is made adjustable as to orientation and location whereby a selectively directioned force may be applied to a given carrier belt to adjust its direction of travel.

Abstract: In a dewatering machine for dewatering wet solids in which an elastomeric covered roll applies pressure upon one or more dewatering valves, the improvement whereby the elastomeric roll covering is a multi-layer covering having a graded hardness across the covering layer. A typical covered roll of such a machine is one in which a soft rubber-like material adheres to the surface of the roll and is covered by a harder outer covering.

Abstract: A machine for filtering slurry includes a frame with two drums mounted to said frame for rotation and spaced apart from one another. An endless, perforated drainage belt is disposed around the two drums to define a substantially horizontal drainage surface on the top of the drainage belt. A vacuum pan is located below the drainage surface to apply vacuum to material on the drainage surface, and a raising and lowering system is coupled to the vacuum pan to selectively support the vacuum pan in sealing engagement with the drainage belt and to selectively lower the vacuum pan away from the drainage belt.

Abstract: A lithium halogen cell comprising a lithium anode, a solid electrolyte comprising lithium halide and a cathode comprising a charge transfer complex of a monomer and a halogen. The monomer is an aromatic tertiary amine which forms a complex with the halogen, and one monomer found to be satisfactory is pyrrole.

Abstract: A lithium halogen cell comprising a lithium anode, a solid electrolyte comprising lithium halide, and a cathode comprising a mixture of halogen and activated charcoal.

Abstract: A lithium-bromine cell comprising a lithium anode, a solid electrolyte comprising lithium bromide and a cathode comprising a charge transfer complex of a monomer and bromine, in particular pyridinium bromide per bromide. Liquid bromine can be added to the solid pyridinium bromide per bromide in the cathode.
