Abstract: The present disclosure provides a system for processing ultramafic material. The system may comprise a reactor for accelerating weathering of said ultramafic material. The reactor may comprise one or more chambers comprising one or more microbes, biological medicators, or enzymatic accelerants to facilitate the weathering of the ultramafic material.

Abstract: There is disclosed a latch mechanism for locking the drawers of items of furniture such as desks and file cabinets. The latch mechanism is manufactured of plastics using injection molding techniques. The mechanism includes an open sided housing having a oppositely directed pair of mounting flanges which extend from the opposite sides of the housing. A longitudinal slot is formed between the flange members and this slot slidably receives the latch member. The cavity of the housing receives a compression spring which protrudes from the open side of the cavity and is received in an aligned slot or through aperture of the latch member. The latch member has a forward and inclined ramp that is mounted opposite and adjacent to the upper cam post of a vertical slide member. The vertical slide member is received in a groove in a upright standard of the furniture, typically in a partition located between the center drawer and a vertically stacked set of lateral drawers of a desk.
