Abstract: This invention relates generally to a system and process for recovery of select minerals and lithium from a geothermal brine. The system and process are configured for the sequential recovery of zinc, manganese, and lithium from a Salton Sea Known Geothermal Resource Area brine. The system and process includes: 1) an impurity removal circuit; then 2) a continuous counter-current ion exchange (CCIX) circuit for selectively recovering lithium chloride from the brine flow and concentrating it using a CCIX unit; and then 3) a lithium chloride conversion circuit for converting lithium chloride to lithium carbonate or lithium hydroxide product.

Abstract: A trailer hitch positioning apparatus directs the driver of a pickup truck or other towing vehicle during backing up to a trailer or other towed vehicle for hitching the coupling elements of the vehicles together. The apparatus includes an infrared light unit mounted on the trailer for transmitting a first collimated light beam of a predetermined horizontal width toward the vehicle. A support bar mounted to the rear of the vehicle carries a plurality of infrared alignment sensors for detecting the first beam and hence when the truck is aligned with the trailer. A position emitter mounted on the trailer emits a second focused infrared light beam that is detected by a position sensor on the truck when the coupling elements of the vehicles are in position to be hitched together.
