An appliance for preparing animal feed, includes a housing, a mixing chamber designed to receive a portion of dehydrated feed and a liquid portion, mobile mixer arranged in the mixing chamber, a consumption chamber, wherein the mixing chamber is removable from the preparation appliance, wherein the mixing chamber, once mounted on the preparation appliance: is rotatable in order to pass from a position mixing the feed ration to a position dispensing the feed ration, and has a gripping portion which protrudes from the housing.

An antibody-resin coupling apparatus quickly and efficiently activates resin beads and couples them to antibodies, while preventing breakdown and crosslinking of the beads, thereby improving downstream column purification processes, extending the usable life of the resin beads, and increasing molecule capture efficiency of the resultant resin-antibody complexes, to allow improved isolation and purification of factor VIII molecules or other drug compounds.

A sealed fluid transfer device and a sealed fluid transfer method includes a first container puncture apparatus, a second container puncture apparatus and a fluid transfer apparatus, wherein the fluid transfer apparatus includes a first container puncture adapter, a second container puncture adapter and a pressure supply unit; the first container puncture adapter includes a sealing element fixed seat, a guided outer casing, a pipeline fixed seat, a first fluid pipeline and a second fluid pipeline; when the sealing element fixed seat is connected with the first container puncture apparatus, a first sealing element is firstly tightly connected with a second sealing element, the first fluid pipeline and the second fluid pipeline respectively pass through the two sealing elements and then communicate with the first container; after being firstly used, the first fluid pipeline and the second fluid pipeline are always in no contact with the exterior.

A method and apparatus for obtaining a product chemistry from a slid block of caustic material is provided. The product is housed within a capsule which is positioned inside a turbulent flow dispenser, which utilizes fluid to erode the block and produce a concentrated solution. The fluid characteristics can be adjusted in the field to achieve a predetermined concentrate level of the solution. The capsule provides a safe and convenient means for handling, storing and shipping the caustic block without exposing the operator or handler to the hazardous material. The capsule includes nested components which can be rotated between a closed or sealed position and an open use position.

A fiber bundle liquid-liquid contactor may comprise: a vessel comprising: a first inlet; a second inlet; a mixing zone arranged in the vessel to receive a first liquid from the first inlet and a second liquid from the second inlet, wherein the mixing zone comprises an inductor fluidically coupled to the inlet for the second liquid; and an extraction zone comprising a fiber bundle arranged in the vessel to receive the first liquid and the second liquid from the mixing zone.

Herein proposed is a device (45) with a first module (10) for the production of a heterogeneous mixture of FORSU which, after the removal of the most coarse inerts, is droppedby gravityin an underlying second module (46), in which along the three chambers (47, 52, 54) in succession to the heterogeneous mixture of FORSU there are collected the further residue coarse inerts as well as the finest and heaviest inerts and there is obtained a mixture with matrix homogenised substantially in the liquid state and thus dischargeable by pumping reliably. In the device (45) the first module (10) is mounted on the underlying second module (46) through the interposition of load cells (59). With the proposed device the FORSU in the liquid state may be pumped directly in an anaerobic digestor thus avoiding an intermediate transport thereof.

The present invention provides a method and system for providing on-site electrical power to a fracturing operation, and an electrically powered fracturing system. Natural gas can be used to drive a turbine generator in the production of electrical power. A scalable, electrically powered fracturing fleet is provided to pump fluids for the fracturing operation, obviating the need for a constant supply of diesel fuel to the site and reducing the site footprint and infrastructure required for the fracturing operation, when compared with conventional systems.
