Abstract: A layer of wires is preliminarily stranded by a layer of strand-through holes, and a first strand cylinder is used for the second pressing and stranding. The next layer of special-shaped single wires is stranded through a second pre-stranding assembly, and then the last layer of wires is stranded through a main stranding mold, thus stranding a plurality of layers at the same time with a compact structure. The outer circumference of the guide roller matches that of the special-shaped single wire, avoiding the reduced quality of stranded cable core. The first rotating connector is bowl-shaped and is provided with a layer of strand-through holes together with a structure in which a first pull rod is in fit with the rotating connector and a structure in which a second pull rod is in fit with the rotating connector.

Abstract: The present invention discloses an etomidate derivative of Formula 1, or a pharmaceutically acceptable salt, a polymorph, or a solvate thereof, a pharmaceutical composition and a kit comprising the same, as well as intermediates and methods for preparing the same, and use thereof. The etomidate derivative of the present invention not only has good anesthetic activity, rapid onset, and short duration of action, but also shows little inhibition to the secretion of corticosteroids in animals, and therefore has both favorable anesthetic effect and safety profiles.

Abstract: A networking communication protocol for a multi-slave cable anti-theft monitoring system, the system including a central office, a master and slaves, wherein the central office and the master are connected based on a GPRS, and the master and multiple slaves are connected based on power carrier communication. Communication in the system is mainly initiated by the master, the master realizes site registration and data reporting at the central office through GPRS communication to aggregate global information of the system. Data interaction between the master and the slaves is achieved through the power carrier communication to complete local data collection and a cable on-off test of the slaves. The master is provided with a periodic collection timer to realize periodic data collection of all slaves on a monitored line.

Abstract: An indefectible cable comprises a cable jacket with cable cores arranged in an inner cavity thereof and a metal ring sleeved on an outer wall thereof. Both ends of the cable jacket are fixedly connected with an anti-extrusion device respectively, through which the cable cores are led out from through-holes. The anti-extrusion device has a metal housing with plastic lining. With the arrangement of a buffer device, the externally applied pressure on the cable is relieved to reduce the damage thereof.

Abstract: The present invention discloses a stable and easy-to-install and remove multi-conductive core cable, an outer protective layer and cable inner core wires arranged in an inner cavity of the outer protective layer. The present invention also discloses a method for processing a stable and easy-to-install and remove multi-conductive core cable, and the method comprises the following steps: S1: preparing a traction rope, an outer protective layer of a cable to be threaded and cable inner core wires; S2: fixedly fastening one end of the traction rope to one end of the cable inner core wires, and threading the end with a hook of the traction rope out through an inner cavity of the outer protective layer; S3: fixing the hook by a wire drawing machine or a traction device and performing traction operation on the cable inner core wires; and S4: controlling an traction rate at not more than 3 m/min until end of the threading of the cable inner core wire.
