An apparatus (10) for producing an orbital movement in a plane (20) is disclosed. The apparatus (10) comprises a lower shaft (40) and an upper shaft (30), being parallelly and eccentrically attached to one another, and a platform (50) mounted on the upper shaft (30). A ring gear (60) is attached to the platform (50) and coaxially rotatable about the upper shaft (30). A gear wheel (80) is coaxially rotatably mounted on the lower shaft (40) and engages with the ring gear (60).

A disposable container, such as a deformable bag, for a fluid, having one or more inlets and one or more outlets and an impeller assembly within the container to cause mixing, dispersing, homogenizing and/or circulation of one or more ingredients contained or added to the container. The region within the container that can contain liquid is funnel shaped, which allows very low fluid level mixing, dispensing while mixing, and a reduction or elimination of vortex formation.

A mixing device comprises a mixing space for mixing bone cement, at least one mixing element supported in the mixing space such that it can rotate, a gear for rotating the at least one mixing element, and at least one elastically deformable energy-storing element that is connected to the gear such that the gear can be driven by an elastic energy from the energy-storing element and such that the at least one mixing element can be rotated in the mixing space by means of the gear upon the release of elastic energy from the energy-storing element. Additionally, a vacuum mixing system and mixing method comprise the mixing device for mixing the bone cement.

An adjustable coupler for linking an oscillating kneader to a gear box. The adjustable coupling has a slide coupler adapted to be slidably received within an output couple of a gear box. The slide coupler has external splines wherein the external splines mate with splines of the output couple thereby coupling rotation of the slide coupler with rotation of the output couple. The internal splines are capable of mating with external splines of a slidably received kneader input shaft thereby coupling rotation of the kneader input shaft with rotation of the slide coupler. A plug in the slide coupler abut the kneader input shaft in the slide coupler and a lock mechanism maintains the kneader input shaft abutted against the plug.

A drive sub-assembly includes a hub extending from a first end face to a second end face along a longitudinal axis. The hub may have an outer circumferential surface arranged to engage a first bearing assembly and an inner circumferential surface arranged to engage an output shaft. The drive sub-assembly further includes a gear attached to the second end face of the hub. The gear may have a second inner circumferential surface that is arranged to directly engage a second bearing assembly.

A disposable container, such as a deformable bag, for a fluid, having one or more inlets and one or more outlets and an impeller assembly within the container to cause mixing, dispersing, homogenizing and/or circulation of one or more ingredients contained or added to the container. The region within the container that can contain liquid is funnel shaped, which allows very low fluid level mixing, dispensing while mixing, and a reduction or elimination of vortex formation.

An apparatus for the recovery of gold from a gold-bearing aqueous filtrate, the process comprising the steps of: (A) Contacting the aqueous filtrate with dibutyl carbitol (DBC) in a two-stage solvent extraction process to remove the gold from the aqueous filtrate into the DBC to form a gold-loaded DBC; and (D) Contacting the gold-loaded DBC with an aqueous acid scrub of hydrochloric acid in a four-stage countercurrent scrub process to remove impurities, e.g., non-gold metal, from the DBC into the aqueous scrub solution to form an impurity-loaded aqueous scrub.

Each stage of the solvent extraction circuit and the aqueous acid scrub circuit is equipped with a mixing assembly and a phase separation tank in a head-tail arrangement such that the mixing assembly of one stage is adjacent to the phase separation tank of the adjacent stage.

A constrictor valve can be associated with a conduit in fluid communication with a mixer to control a flow of cementitious slurry discharged from the mixer through the conduit. The constrictor valve can include a constrictor housing, a webbing constriction assembly, and a drive mechanism. The webbing constriction assembly includes a pair of rotatable members rotatably mounted to the constrictor housing and a plurality of webbing straps connected to the rotatable members and wrapped around the conduit. The drive mechanism includes a drive shaft and a gear assembly configured to rotate the rotatable members in opposing winding directions in response to the drive shaft rotating in a tighten direction to wrap the webbing straps tighter around the conduit to compress it and to rotate in opposing unwinding directions in response to the drive shaft rotating in a loosen direction to loosen the grip of the webbing straps on the conduit.

A drug reconstitution device comprising a disposable liquid transfer unit (18) and a reusable control and drive unit (16) removably connectable to the liquid transfer unit, the liquid transfer unit including a housing (26), a docking interface (30) configured for coupling at least one of the first and second constituent containers (2, 4) to the housing (10), and a pump engine (28) and fluid flow system (36) configured for transferring liquid from the first constituent container (2) to the second constituent container (4). The control and drive unit comprises a pump drive (22) configured to drive the pump engine during a liquid transfer action, the pump drive comprising a transmission output coupling (34) removably engaged with a transmission input coupling (50) of the pump engine (28) when the liquid transfer unit and control and drive unit are connected.
