Different Types

A new methodology for determining and optimizing the contrast of the technological laser marking process has been developed. It can evaluate the quality of the markings regardless of the type of material and the type of laser system. To perform the test analysis, a specialized test field is programmed, which including the change of two of the main parameters influencing the marking process: the linear energy density (LED) and the linear density of the pulses (LDI). Marking of a test field consisting of squares of a certain size is done by means of a raster marking method with a constant step between the lines. The results are processed with a digital camera and specialized software. The maximum blackening is compared with the background of all fields and is juxtaposed with the effective energy needed to obtain a certain contrast. Several consecutive iterations are made, with each of the following experiments excluding the variants with least contrast. Thus, the study consistently brings the result to a minimum working area of the basic technological parameters, providing the user's desired contrast of the marking. The developed author's method of automatically determining the contrast of the laser marking reduces the time for preliminary experimental research and gives a reliable and subjectively absent way of qualitatively marking different types of industrial products.

Common Operation

Laser engraving is one of the most commonly used laser procedures for interacting with laser material. The speed, ease of use and high precision make it an attractive process for use by manufacturers and for removing insulation from various cables. Cable stripping is a particularly common operation in aeronautics. The aircraft is equipped with several hundred kilometers of cables to control and operate the various systems of the aircraft and most of these cables must be stripped at both opposite ends to allow the cable to be connected to different terminals.This report examines the possibility of removing polyvinyl chloride (PVC) insulation from telecommunication cables of different colours and thicknesses up to 600 [μm]. The experimental measurements of the study were performed with a low-power continuous CO2 laser system. The main functional dependence of the width and depth of the ablation zone on the main technological parameters, such as the average power and the processing speed, have been experimentally studied. The zones of laser impact are observed with a laser microscope. The graphic dependencies are analyzed in order to determine the optimal working intervals.The analysis aims to help solve problems related to the application of small diameter communication cables in the production of various communication devices and components for the needs of industry.

The causative agent Listeria monocytogenes causes listeriosis, a severe foodborne illness associated with high mortality. Rapid and sensitive methods are required to detect and identify this pathogen in the food production process. The article presents the results of research on the development of technological parameters for the production of biopreparation based on the bacteriophage L. m 4 UlSAU for quick identification of bacteria of the genus Listeria with its help. It was established that for the production of L. m 4 phage of UlSAU with maximum titers, the optimal parameters are: multiplicity of MOI 1 infection, cultivation temperature-28°C, incubation time of the phage/ culture system – 6 hours. Based on these results, we have offered technological scheme for the production of phage biopreparation L. m 4 UlSAU, which includes the following steps: confirmation of biological properties of indicator phage and increasing its titer (if necessary), verification and confirmation of biological properties of indicator culture, production of phage biopreparation and control of its indicators. Accelerated scheme for Listeria identification was offered with the help of prepared biological product based on L. m 4 bacteriophage of UlSAU. The scheme was tested on samples of chicken meat and minced meat semi finished products artificially contaminated with Listeria monocytogenes bacteria in concentrations 101-105 CFU/ml. It was established that the proposed scheme of listeria identification allows to reduce the duration of studies by 84 hours in comparison with the traditional bacteriological method and to detect listeria at a concentration of 100 CFU/ml (g) in 82 hours. The phagoidentification time at the pure culture typing stage is 18 hours.

The paper is devoted to investigating the position of the anode spot on the cut edge during high-precision plasma processing and studying the trajectory of the melting products flowing from the cut edge. The material of samples is structural steel of St3 (<strong>GOST 14637-89)</strong> having the thickness of 3, 4, 5, 6 and 8 mm. The formation of the cut edge was carried out according to the HiFocus technological scheme of cutting by using the equipment manufactured by the Kjellberg firm (Germany). It was found that among technological parameters such as current, cutting speed, pressure and flow rate of cutting and swirl gases considered in the paper the greatest influence on the position of the anode spot on the cut edge is made by the cutting speed. For the investigated technological scheme of cutting the ratio between the anode spot and the thickness of the cut material lies in the range from 0.42 to 0.47. The optimization of the processing speed is based on studying the trajectory of the melting products outflow from the cut edge.
