Abstract: FIELD: knitted production. 
     SUBSTANCE: invention relates to the technology of knitted production, namely to methods of knitted fabric width change at manual or machine knitting of knitwear by single-piece smooth curling, which can be used in knitting seamless skirts, dresses, sleeves of products, and other seamless and stitched products with conical shape. According to the method, in the web the stitches are determined, which affect the web width change, the number of loops in these stitches is calculated, each such stitch line is divided into an even number of sections with the estimated number of loops in the section. Sections are used to determine places in said loop rows for making additions and decreases of loops, wherein points are set in accordance with four values, which are cyclically and sequentially by one value assigned to each such loop line, namely the first value "at the end of even sections", the second value "at the end of odd sections", the third value "at the beginning of odd sections", the fourth value "at the beginning of even sections". Thus, a cycle zone is formed vertically, including at least four loop rows influencing the width of the web, each of which has a place for performing actions to change the number of loops in two adjacent sections – even and odd. Cloth is knitted by repeating the cycle zone horizontally, i. e. over the entire width of the web.

Abstract: FIELD: electrical engineering.  
     SUBSTANCE: invention relates to electrical engineering. The expected result is achieved by collecting data on the state of the equipment and its operating parameters, monitoring the state and control system, and before it is turned on, remote control agents and an additional computational control module are introduced into it to launch remote control agents of the equipment. Before launching remote control, primary equipment is monitored, which is included in the control system through a variety of communication devices with the object. At startup, the operational management teams use the remote management agent to check the indicators of local equipment for compliance with its parameters with the permissive management rules. If the command is issued in accordance with the rules of operational management and these rules can be detected by an additional computing module and a response can be received, then the control of the primary equipment is either permitted or blocked. If there are not enough local indicators of the state of the equipment, then a request is sent through the first agent to the second agent located in another local control system connected to the equipment of the first local system. The first agent requests the result of obtaining a criterion that is missing to identify the rules for making an enabling or prohibiting decision. From the second agent that has received the request, a response is received to the request from the first agent and either a response is sent in the reverse direction, or the request is passed to the third agent. Requests are sent until all agents are polled. If responses to requests are not received from the agents, the command of the first agent is blocked, and when the first agent receives a response to all requests, the first agent is permitted or prohibited from managing the object.  
     EFFECT: increased safety of managing an industrial facility.
