Abstract:
An atomizing device, comprising an atomizing body (1 ) with an inlet (16) for receiving a fluid under increased pressure, and with at least one set of outflow ports (18) for allowing the fluid to escape on a delivery side with forming of a vapour. Imaginary central axes of the outflow ports directed in a flow direction herein enclose a mutual angle (α) in order to intersect each other at an intersection (S). The atomizing body comprises a roof (21) and a bottom (11) which extend over at least a first distance (dl) beyond the set of outflow ports (18) and bound a vaporizing space (17) on either side. The intersection (S) of the imaginary central axes of the outflow ports lies at a second distance (d2) from the set of outflow ports, wherein the second distance (d2) is greater than the first distance (dl) and extends beyond the vaporizing space (17). In a further aspect of the invention the atomizing body is able and adapted to capture supplied radiation, thus forming heat. In a further aspect the atomizing body is in an envelope which at least on a boundary layer is adhered with a boundary layer to the atomizing body.

Abstract:
In an electroforming method for making metal products (10) having a pattern of openings (9) separated by dykes (8) using a mandrel in an electroplating bath, metal from the bath is deposited on at least two electrically mutually insulated regions. Said regions comprise at least one main pattern (3) for product dykes (8) to be formed, which main pattern (3) is electrically insulated from at least one ancillary pattern (5) for a reinforcement (7) to be formed. In the method according to the invention, first the ancillary pattern (5) is connected to a current source in order to form reinforcement (7) thereon and in order to effect an electrical connection between the ancillary pattern (5) and the main pattern (3) by means of the growing metal. During the continuation of the method, reinforcement (7) is thickened and the product dykes (8) are formed. A strong product having different thicknesses is therefore obtained in one step. A mandrel suitable for use in the method is also described.
Abstract:
A device for generating micro spheres from a fluid (13) comprises an injection plate (6) which comprises at least one defined injection channel (1) having on an inlet side an inflow opening for receiving the fluid and on an outlet side an outflow opening for delivering micro spheres (12) formed from the fluid. The device is provided with feed means for carrying the fluid through the injection channel and is in open communication, on a side wall thereof, with at least one secondary channel (10) at least at the position of a break-up point where at least during operation a flow of the fluid in the injection channel breaks up into separate parts. The secondary channel is intended and adapted to comprise an auxiliary fluid at least during operation and at least at the position of a break-up point. For at least a part of the first fluid an inflow resistance of the secondary channel is greater than an inflow resistance of the injection channel. Such a device is employed in a method for injecting a first fluid into a second fluid and a cross-flow of a second fluid is guided over an outlet side of the injection plate.
Abstract:
A membrane filter comprises a membrane provided with pores with a pore size between 5 nm and 50 mu m. The membrane may easily and reliably be processed with use of silicon micromachining through depositing a relatively thin membrane layer on a support, by means of a suitable vapour deposition or spincoating technique, after which perforations are made in the thin membrane layer, for example by means of etching with aid of photo-lithography or an imprint technique. Such a membrane is very well applicable for the separation of biological cells. A membrane with a thickness smaller than the diameter of the perforations is in particular suited for the separation of vulnerable cells and may be used as a leucocyte filter or as a blood plasma separator of blood concentrates. A microfiltration membrane according to the invention may very well be applied as a support for the deposition of a separation layer for ultrafiltration, gas separation or catalysis.
Abstract:
Embodiments of the present disclosure are directed to the separation/capture of specific cells and/or contaminants, as well as the determination, monitoring, and treatment of cancer. Moreover, some embodiments are directed to methods, systems and devices for removing cancer, stem and/or tumor cells in vivo or in vitro from a bodily fluid to prevent or impede the proliferation of a cancer. Some embodiments provide a blood-compatible filter comprising, for example, a membrane provided with a number of openings (preferably precise) which yield minimal detrimental effect both quantitatively and qualitatively on cells present in the bodily fluid during the separation process. For example, in some embodiments, a majority percentage of circulating tumor cells are captured by a filter while a majority percentage of leukocytes, for example, are allowed to pass, where the passed leukocytes retain their vitality.

The present invention discloses a fluid handling system comprising at least one membrane provided with pores, a housing and means to rotate the membrane in the housing. The membrane is a membrane filter with a low flow resistance, in particular a microsieve. Further the invention relates to uses of the fluid handling system, namely for atomization, in particular emulsification, and for filtration.
Abstract:
The inorganic membrane consists of a macroporous inorganic support and an inorganic membrane layer. The membrane layer is formed through depositing an inorganic layer by "Chemical Vapour Deposition" or "sputtering" on the macroporous support, onto this inorganic layer a photo-lacquer layer is formed, this photo-lacquer layer being exposed to a regular mask pattern with the use of a suitable source, this lacquer layer being developed, and in the inorganic layer the mask pattern is etched by a suitable etchant, thus forming the membrane layer. The pattern of the membrane layer may be given any particularly design, practically with a repetition rate in the range 0.1-10 mu m. It is thus conceivable to separate not only particles according to their size, but also to their shape. The membrane layer can be deposited very thinly in comparison to the dimension of the pore size, enabling a large flux, a reduced clogging and a minimal damage to particles or cells.
