Abstract: A device for separating at least one component from a gas mixture, comprising at least a pair of adsorber units, each adsorber unit comprising an envelope defining an inner volume having a lower end zone and an upper end zone. There is at least one adsorbent layer between the lower and upper end zones. A first conduit has one end communicating with the lower end zone, and a second conduit has one end communicating with the upper end zone. The adsorber units of the pairs are superposed and one of the first and second conduits of each adsorber includes a vertical central tube portion. The vertical central tube portions of the pair of adsorber units are mechanically interconnected in endwise abutting relationship. The adsorber units are superposed such that the envelopes of adjacent units leave an intermediate space therebetween. The first and second conduits each have an outer portion extending out of the envelope in the intermediate space.

Abstract: A machine for wet-processing ore to recover precious metal values such as gold. The machine includes a rotating, inner, perforate, hollow, ore-receiving drum and also a vibrating cradle for receiving water, sands, and other relatively fine material as is discharged through the perforations of such drum. The drum is provided with an inner spiral protuberance for advancing materials from the receiving to the discharge end thereof. Additionally, impact means as are disposed between turns of such spiral are employed to advance rapidly, larger materials such as rocks and coarse gravel through the drum. The cradle is provided with an auger for discharging materials from the cradle; said cradle is so designed and positioned as to concentrate finer materials such as gold-containing black sand, proximate a lowered, reservoir-end thereof for discharge.
