Abstract: The inventive method for forming nano-dimensional clusters consists in introducing a solution containing a cluster-forming material into nano-pores of natural or artificial origin contained in a substrate material and in subsequently exposing said solution to a laser radiation pulse in such a way that a low-temperature plasma producing a gaseous medium in the domain of the existence thereof, wherein a cluster material is returned to a pure material by the crystallization thereof on a liquid substrate while the plasma is cooling, occurs, thereby forming mono-crystal quantum dots spliced with the substrate material. Said method makes it possible to form two- or three-dimensional cluster lattices and clusters spliced with each other from different materials. The invention also makes it possible to produce wires from different materials in the substrate nano-cavities and the quantum dots from the solution micro-drops distributed through an organic material applied to a glass.

Abstract: A method for producing a metallized image on a sheet material includes impregnating the material with a metal salts-containing solution and exposing the specified material points to a pulse laser radiation. The interaction of the pulses with the solution within a laser spot irritates a photochemical reaction resulting in a metal ion reduction into the elementary state thereof by associating the required number of electrons and deposition of metallic film which is firmly fixed to the filler of the sheet material in the laser spot area on the material surface. In case of sufficient laser radiation power, a recess is formed on the sheet material surface, and the metallic film is deposited on the bottom of the recess.

Abstract: The printing machine is designed to print different polygraphic matter without replacement of the printing form upon transition from printing one publication to another. The machine includes a printing form in the form of a mesh, and operates by filling all of the mesh cells with ink and forcing the ink through selected mesh cells by the light-hydraulic effect, which is to heat part of the ink volume in a cell with a laser beam pulse which in turn ejects all of the ink from the cell toward a receiving medium.

Abstract: The method for printing is carried out by creating pressure pulses at individual points of an ink layer which has been applied onto the surface of a continuous smooth plate, focusing a light beam of a laser on those points from the side of the opposite surface of the plate. Pressure pulses are developed due to the light hydraulic effect at the border of the surface of a plate, made of transparent material, and a layer of ink applied thereon, or due to the conversion of light radiation into acoustic when the light beam of the laser is absorbed by material which is not transparent for its wavelength. The printer has a device for deflecting the light beam over the surface of the plate to excite pressure pulses in the ink layer at points predetermined by a program.

Abstract: A method of ink-jet printing is carried out by focusing a light beam from a quantum generator onto an expendable liquid printing material in a jet from the direction of the open end of the jet, with an information carrier placed in front of the open end, in order to generate a pressure pulse ensuring the expulsion of a droplet of the liquid onto the carrier. The method is carried out by directing the light beam onto the material in a jet either at an angle to its surface between the jet and the carrier, or through a carrier which is transparent to the wavelength of the beam. An ink-jet printing head has rows of jets, each with one blind end formed in the body of a driving drum.

Abstract: A printing method is performed with an ink jet print head including a matrix of groups of orifices positioned in parallel rows. Each group has a plurality of orifices which each eject fluid of a different color. The color fluid, e.g. ink, is simultaneously propelled through the orifices of each group selected for printing and onto an information carrier which is stationary in relation to the matrix. The print head has a multilaminate structure with additional layers (20-25) of an underlay (10) equal to the number of print colors. The orifices (BK, Y, R, B) are divided into groups of adjoining orifices with the same number of orifices in each group and with the orifices in each group disposed in a square arrangement. The inlet openings of all orifices which eject fluid of the same color are placed in a single additional layer of the underlay. Feeder channels (26-29) are made in each additional layer of the underlay and cross the orifice openings (11-14) in that layer.

Abstract: The invention relates to apparatus for bundling stacks of newspapers. The apparatus includes a rollerway for conveying a stack into the wrapping-up zone defined by an endless roller conveyor and a frame, a device being mounted to each side of the rollerway for protecting the newspapers in a stack from crumpling, including a pivotable bell crank rotatable into two alternative positions in one of which the free arm of the bell crank is introduced into the area to be occupied by the end faces of the bundle-to-be and is aligned with the bottom edge of the stack. In the other position the arm is retracted from under the wrapping paper, to enable the stack to leave the roller conveyor unobstructedly.

Abstract: A tucker folder having a pair of rotating folding rollers adjacent to which at least one other pair of similar folding rollers is located. The rotational centers of the rollers in these other pair of rollers has an arc of the same radius as that of the first pair. The folder of the tucker folder is equipped with means for alternating interaction between the tucker blades and the two pairs of the folding rollers to divide the newspapers emerging from the folder into separate streams. A cam controlling the operation of picking pins is capable of being shifted with respect to the spaces defined between the folding rollers, depending on the interaction between the tucker blades and the respective pair of the folding rollers, to form a transverse fold in the middle of the paper sheet, irrespective of the stream taking this sheet.

Abstract: This invention relates to apparatus for printing books or magazines and may be the most efficiently used in the printing apparatus having the provision for the collection of booklets into stacks with subsequent compression thereof. The arrangement is provided with two spiders and receiving bins located thereunder for collecting stacks of booklets, each bin having a driven moveable or sinkable bottom for transferring the stacks to pallets of a discharge conveyor. Each of the bins is provided with a slot in one of the side walls thereof for feeding rigid boards therein to be placed over and beneath the stack being collected, respectively, there being provided a magazine for these boards having driven pushers for feeding the boards one-by-one into each of the bin.

Abstract: The invention relates to conveying means and may be used to the utmost effectiveness in automatic continuous lines of performing operations on piles of printed newspapers. The apparatus is provided with a rollerway for conveying piles of newspapers, and discs mounted on respective shafts between the rollers of the rollerway. Each disc has two portions having different profiles, and on one of the portions there is a semicircle, and the other portion a semi-ellipse, with the bisection line extending along the major axis of the original ellipse, and with the length of the minor axis of this ellipse being shorter than the spacing between the axis of the respective shaft and the load-supporting surface of the rollerway. This apparatus ensures the conveying of piles of newspapers without affecting their shape, and which features a simplified structure.

Abstract: The present invention relates to conveyors for the transportation of piles of newspapers and can be used with the utmost effictiveness for conveying piles of newspapers delivered by a web-fed rotary printing press.The disclosed conveyor for piles of newspapers comprises a chain supporting carriages carrying clamps thereon in the form of fork-shaped flaps together making a closed receptacle for piles of newspapers, with one of the fork-shaped flaps having the prongs thereof bent at both ends toward the other one of the fork-shaped flaps, with the central part of each one of these prongs being a curved one, with the convex portion facing the same direction as the bent ends, and with the flaps being associated with flap opening mechanism. The disclosed structure provides for reliable retention of the newspapers in the clamp preventing displacement of the newspapers in the pile being conveyed.
