A first outlet of the first separator unit is connected to the inlet of the second separator unit, a second outlet of said second separator unit is connected to the inlet of the first separator unit, a first outlet of the second separator unit is connected to a system outlet, and feedback means is...

The present invention relates to separation and finds application in the removal of liquid from particulate material having associated liquid. The invention provides a process and apparatus for the removal of liquid from a particulate material having associated liquid. In accordance with the invention gas is passed through a bed of particulate material having associated liquid, gas which has thereby taken up liquid is removed from the bed and the particulate material is then removed from the bed...

A method of the present invention separates lightweight grains from raw grains. In a primary separation step, raw grains containing the lightweight grains are whirled upward with primary air along the inner wall of the cylindrical section for allowing raw grains and part of the lightweight grains to stay in a certain flow area by frictional resistance with respect to the wall surface generated by whirl, and to drop into the conical section on the downside by their own weight. In a secondary sepa...

A device for separating ions from a fluid stream is disclosed. The device includes multiple chambers in fluid communication with one another. A first chamber has an inlet, and a last chamber has an outlet. The inlets and outlets of intermediate chambers are connected to one another so that fluid flows in a circular pattern through each chamber. A magnetic field extends through the chambers perpendicular to the flow. The magnetic field induces a force on the ions, moving ions of one polarity to w...

A separation module is provided having a housing, a filter within the housing and at least one outlet and one inlet. The outlet and inlet are positioned to mate with fittings of a pump housing. A stationary receptor positioned between the pump housing and the separation module has a pivot line and two shelves on its outer surface which permit fitting the separation module in a stationary receptor adjacent the pump housing.

The invention relates to an equipment for fractionating a solution by a sequential SMB process, which equipment comprises a feed column and one or several other columns, which include a chromatographic separation resin bed. The equipment of the invention is characterized in that the feed column consists of or comprises a compartment where the resin bed is shallower than that of one or more of the other columns of the equipment. The invention also relates to a method for fractionating a solution ...

A separation analyzer for transferring solutions, while changing mixing ratios of the solutions, wherein a flow passage from a first pump, a flow passage from a second pump, and a passage for sample introduction section, the flow passages being connected, which further comprises a flow switching means for temporarily storing the solutions, whereby the flow switching means alternatively makes a first state for pushing out the solutions in a second sampling loop to the sample introduction section ...

A composition comprising colloidal Fe.sub.3O.sub.4 particles coated with streptavidin is disclosed. These particles can be used in a method for separating biotinylated compounds from a solution in which the biotinylated compounds bind to the streptavidin-coated particles which are attracted to a surface by a magnet. Also disclosed is a method for making said streptavidin-coated composition, said method comprising the steps of forming colloidal Fe.sub.3O.sub.4 particles by mixing aqueous FeCl.sub...

An individual tetrahydrocannabinol isomer of interest is separated from a mixture containing two or more such isomers, by treating the mixture with an isocyanate or isothiocyanate of formula I: R--(CH.sub.2).sub.n--N.dbd.C.dbd.X (I) where R represents an aromatic ring optionally substituted with one or more electron withdrawing groups, n=0 or 1 and X is oxygen or sulphur; so as to produce a crystallizable THC carbamate of formula II: ##STR00001## wherein X and R are as defined above, R' is a C.s...
