Abstract: The present disclosure relates to a method and a device for application of liquid polymeric material onto the active spinning zone of the cord of the spinning member of the spinning electrode, where the application means moving reversibly along the active spinning zone of the cord in the device for production of nanofibres through electrostatic spinning of liquid material in electrostatic field of high intensity between at least one spinning electrode and against it arranged collecting electrode. The liquid polymeric material is applied onto the cord around its whole circumference without any contact with gaseous environment in the spinning space, where the application means reversibly moves, whereas while the cord is leaving the application means the thickness of the layer of the liquid polymeric material is being reduced and immediately after leaving the application means the process of electrostatic spinning of the liquid polymeric material applied on the cord is started.

Abstract: A device for production of nanofibers through electrostatic spinning of the liquid matrix in electrostatic field between at least one spinning electrode and a collecting electrode positioned opposite thereto, while the spinning electrode contains at least one spinning member containing the cord, which comprises a straight section which is parallel with a plane of depositing the nanofibers and/or with the collecting electrode and it forms an active spinning zone of the cord. The cord of the spinning member is stationary or is displaceable in a direction of its length or is movable in a direction of its length either discontinuously or continuously and to the cord there is assigned a device for application of the liquid matrix on the cord in a direction of length of the cord.

Abstract: A scanning confocal microscope optical system overcomes the difficulties of previous devices and can be used in diagnostic applications that are inaccessible to previous devices. The optical system for forming an image of a subject illuminated by light from an illumination system includes a Nipkow disk that is perpendicular to a light propagation path and that has a surface upon which a plurality of pinholes are distributed substantially symmetrically about an axis perpendicular to the surface of the disk. The system further includes components for projecting an image of a first set of the pinholes onto a second set of the pinholes, the image being formed of light transmitted by the first set of the pinholes when the first set is illuminated by light that impinges on a first side of the disk. The system further includes a collective lens and a first objective lens for focussing light transmitted by the second set of the pinholes onto the subject and for collecting light reflected by the subject.

Abstract: An arrangement preventing the creation of secondary images in the case of the so called "tandem scanning" of objects by means of a scanning disk with spirally arranged openings similar to a Nipkow disk and a mirror provided on one of its surfaces with a semitransparent mirror layer in which said mirror has a thickness sufficient to space apart the light rays reflected from the mirrored and unmirrored surfaces so that only the light ray reflected from the mirrored surface will pass through the scanning disk.
