FORMULATION AND IMPROVEMENT OF TECHNOLOGICAL SOLUTIONS FOR WASTEWATER TREATMENT OF AGRICULTURAL REPAIR ENTERPRISES

The article presents the main production cycles of engine repair at a repair and mechanical plant. The main production cycle of engine repair at the repair and mechanical plant consists of external steaming of the unit in the steaming chamber with the discharge of the formed effluent into the pre-fabricated well. Next the disassembly of the en-gine into individual components is carried out, then they are cleaned in cross washing machines with periodic discharge of spent detergent solutions into the prefabricated tanks. After restoration of details the assembly of the diesel engine and its test on stands is carried out. The necessary parts are electrochemically galvanized, chrome-plated or coated with iron. Several local wastewater treatment schemes on the plant with utilization of valuable components and their reuse are offered. Wastewater and waste process solutions are conventionally divided into low-concentrated and concentrated. Low-concentrated wastewater includes effluents from the diesel test site, flushing water from plating baths, and discharge of a revolving diesel cooling system. A scheme for wastewater treatment from petrole-um products and substances in the form of suspensions has been developed and researched, which allows reusing wastewater from the re-verse water supply to the diesel test site. The schematic diagram of the reverse water supply of the diesel test area will consist of a column electrical flotation coagulator, contaminated water collectors, saturators and pumps. A scheme of electrochemical purification of waste detergents has been developed, which includes receivers of detergent solution, preliminary settling of coarse impurities, column electrical coagulator-floater with soluble aluminum electrodes, electrolyte collection. The peculiarity of the device is the operation of the electrode system in a pure electrolyte, which eliminates the possibility of contamination and passivation of electrical and chemical processes. The electrically generated coagulant is dosed into the reaction chamber, mixed with the detergent solution, coagulates and floats the contamination, which allows to extend the service life of the detergent solutions in two or three times.

Vauquez erythremia case

Patient G., 44 years old, married, the wife of a mechanical plant worker, entered the therapeutic department of the Zlatoust city hospital on March 10, 31 (case history No. 1442) with complaints of pain in the left side, weakness, lack of appetite and poor sleep. In December 1930, the patient fell on her left side, there was a fracture of the eleventh rib, after which she began to notice progressively worsening pain in the left side.

Calculation of the labor potential of the company on the example of “Foundry and Mechanical Plant” OJSC

This article is dedicated to practical implementation of quantitative assessment of labor potential of the company. The author provides the results of implementation of the original methodology for calculating labor potential of the company on the example of “Foundry and Mechanical Plant” OJSC in the city of Semyonov of Nizhny Novgorod region. In the course of development of this methodology on the basis of expert assessments, the author determines the elements of labor potential and establishes correlation between them in order to calculate labor potential of the company in points. To determine the score of labor potential of the company is used the system of private indicators that characterize and substantiate each element: human resources, educational, professional, innovative, social, and economic. This process was implemented at the plant in cooperation with its management; all necessary data was collected, intermediate and total scores were calculated. The obtained total score for 2020 was 101.130 points, which is higher than the standard value of 100 points, and testifies to the good labor potential and positive dynamics of the company. The theoretical importance of the acquired results lies in the fact that they can serve as the foundation for the development of methodological guidelines for quantitative assessment of labor potential of the company. Practical relevance lies in the possibility of their actual application in human resource management of the company “Foundry and Mechanical Plant” OJSC.

The Design Specificity of the Ammunition Supply and Storage Mechanism in Naval Weapon System OSU-35

The article presents the design of the ammunition supply and storage mechanism developed for the 35 mm Naval Cannon, which is an integral part of the Naval Weapon System OSU-35. The system for supplying and storing ammunition for the 35 mm KDA automatic naval cannon, was developed and manufactured in Zakłady Mechaniczne (Mechanical Plant) ‘Tarnów’ S.A. in Tarnów (Poland), as part of the project ‘35 mm Automatic Naval Cannon KDA with a Fire Control System Installed on the Ship Using the Sea Version of the ZGS-158 Integrated Tracking Head with Fire Control System’. The manufactured ammunition supply and storage mechanism used in the 35 mm Naval Cannon has been tested in the factory, military training area and verified in real conditions during research conducted at sea. The sea tests of the Naval Weapon System, installed on board of Polish anti-submarine corvette ORP Kaszub, were carried out in real conditions and included tests of shooting at surface and air targets at various parameters and distances to the target. The results of the tests carried out showed that the adopted design solutions met the assumptions that had been set and defined for the development of the 35 mm Naval Cannon, which is an integral part of the Naval Weapon System.

Remote Controlled Weapon Stations - Development of Thought and Technology

The publication presents the Remote Controlled Weapon Station (RCWS) family, designed, produced and developed at Zakłady Mechaniczne (Mechanical Plant) ‘Tarnów’ S.A. in Tarnów (Poland). The paper describes the functionality, scope and purpose of research and development and the prospective directions of its future development. The publication describes the most important functional elements of RCWS, the most important performance parameters as well as scientific and typically engineering issues encountered during the development of this range of products. Additionally, we have provided examples of the use of RCWS family products in military equipment used by the Polish Armed Forces and proposals for use in equipment that is pending implementation. The publication presents the RCWS family, from the least to the most advanced and versatile module. It also touches upon the classification of remote controlled military equipment, as well as the methods of its use on the contemporary battlefield. The publication also illustrates the benefits of using remote controlled equipment on the battlefield - such as providing complete, or at least sufficient isolation of the soldier from the dangers of the battlefield, while supporting correct decision-making and enabling advanced observation, recon and tracking of selected targets.
