Abstract: A conveyor which can be used to route oriented objects, such as caps, covers, lids, etc. from a finishing machine of the type including a belt, a vibrating bowl or other. The conveyor includes a module having a vertical conveyor in the form of a column with an adjustable height and an intermediate conveyor in the form of a casing which is disposed between the finishing machine and the column. In addition, the module includes channel-type devices for guiding the objects and devices for propelling the objects, in the form of jets of air pulsed through eyes. The channel and the eyes form a continuous assembly between the finishing machine and the upper end of the column. The conveyor also includes devices enabling the automatic ejection of objects from grooves provided in the belt of the machine.

Abstract: An improvement to finishing machines that are used to orient objects. The finishing machine includes a hopper for receiving loose objects, such as lids, and an endless belt for extracting the lids from the hopper. The belt moves vertically upwards with the lids and sorts the lids automatically, such that only correctly-oriented lids are retained.

Abstract: The invention relates to a conveyor which can be used to route oriented objects, such as caps, covers, lids, etc. from a finishing machine of the type comprising a belt, a vibrating bowl or other. The inventive conveyor consists of a module (12) comprising (i) a vertical conveyor in the form of a column (14) with an adjustable height and (ii) an intermediate conveyor in the form of a casing (13) which is disposed between the finishing machine and the column (14). In addition, the module (12) comprises channel-type means (15) for guiding the objects and means for propelling said objects, in the form of jets of air pulsed through eyes (32). The channel (15) and the eyes (32) form a continuous assembly between the finishing machine and the upper end of the column (14). The conveyor also comprises means enabling the automatic ejection of objects from grooves (7) provided in the belt (3) of the machine.

Abstract: There is disclosed a process useful for the extraction of gold, silver, and the platinum metals from precious metal containing ores which poses no threat to the environment or the ground water. The process utilizes sodium bromide, sodium chloride, and potassium monopersulfate to react with a water slurry of the precious metal containing ore which has been reduced to a minimum particle size of 250 mesh. The leaching out of the gold, silver, and the platinum metals occurs when the oxidation-reduction potential is maintained at +600 to +900 with the pH at 3.2 to 3.6. After the precious metals have been dissolved into solution, the ore tailings are filtered and discarded. The pregnant leach liquor is pumped to a holding tank where it is subsequently reacted with a solution of sodium hydroxide and sodium borohydride at a pH of 8.2 to 8.6 and the oxidation-reduction parameter held at -550 to -650.
