Abstract: A capturing of target cells from a biological sample is achieved by inducing a flow of the biological sample in a flow channel (30, 60) of an upstream microfluidic device (1). Target cells present in the biological sample are captured in cell channels (20) of the upstream microfluidic device (1). Once at least a minimum number of target cells are captured in the cell channels (20), the flow of the biological sample in the flow channel is reduced and are verse flow is applied at the upstream microfluidic device (1) to release the target cells captured in the cell channels (20) of the upstream microfluidic device (1) and enable transfer the target cells into cell channels (120) of a downstream microfluidic device (100).

Abstract: A first sheet, includes, but is not limited to at least one attachment region inclined at an angle to a sheet plane. The first sheet is arranged on a second sheet so that the attachment region of the first sheet is spaced at a distance from the second sheet. A magnetic field pulse is applied so as to cause a force on the attachment region in directions generally perpendicular to the first sheet plane and the second sheet plane so that the attachment region of the first sheet is driven against the second sheet with sufficient force to produce a cold-welded joint between the attachment region of the first sheet and the second sheet.

Abstract: The present invention provides an arrangement with special lights for a vehicle which has a stage with at least two headlights. The arrangement is to be fastened to the front portion of the vehicle and contains two types of holders. One of the holders is in the form of a quick connect and a part which projects outside the radiator grill. Accordingly, the arrangement can be mounted and dismounted from the vehicle.

Abstract: The invention relates to a wrapped pulp bale of the kind which, apart from a proper bale, comprises an enveloping wrapping which is folded along opposite faces of the bale while forming mutually overlapping parts in which the paper lies in two or more layers on top of each other. For holding the wrapping against the proper bale, sets of lugs (26) are provided in the overlapping parts of the wrapping, each set of lugs including a number of lugs corresponding to the number of paper layers, which are punched out from the paper layers while leaving through holes therein, and folded along a common folding line (25) as well as jointly inserted between the inside of the innermost layer of paper and the outside of the bale in order to be held therebetween.

Abstract: The invention relates to a monitor for ejecting jets of water, foam or mist, comprising a pipe system attached to a foot support, which is rotatable on the support. The foot support is characterized by a lower disc-shaped part (10), an upper part (13), which is rotatable with respect to the lower part (10), and a fastening ring (15) which presses a flange (14) of the upper part (13) against the lower part (10). The invention consists of arranging through-holes in the upper part (13) from the central hole to the gap between the fastening ring (15) and the flange (14). A hydrostatic bearing between the flange (14) and the fastening ring (15) has been brought about so that the flange and the upper part (13) can be easily rotated.

Abstract: The invention relates to a method of extinguishing fires in closed or open spaces using water and foam. The method is characterized in that water mist is first produced with the air available in the space without air supply from outside until the temperature in the combustion gases has fallen below a predetermined level or during a predetermined period of time, whereupon foam is produced with the air available in the space without air supply from outside and with a suitable speed for filling the space and extinguishing the fire. The invention also includes a means for performing the method comprising units for producing water mist and foam in the space and a closing or controlling valve (33) which, in dependence upon the temperature in the combustion gases or period of time elapsed from the start of the water mist production, controls the amount of foam liquid added to the water.
