A cable dressing ring for organizing a cable bundle is provided, wherein, the ring is separated in two halves that are associated by a joint mechanism at one end, and that are securable to each other by a locking mechanism at the other end, such that a user may lock the ring when needed to clamp the ring around the inner cables of the bundle, and wherein, the ring has a plurality of self-locking cable holders on the outside circumference of the ring, for holding the outer cables of the bundle organized while pulling the ring toward one end of the bundle.

A slide fastener (1) comprising a slider (5) with a pull-tab (6), and a top stop (4) with a retaining element (20) disposed to act against a contact face (30) of the puller (6), when said pull-tab (6) is in a suitable locking position, to prevent the slider (5) from sliding away and keep the fastener (1) closed.

The invention provides an extraction method for mercury compounds in sediments. The extraction method comprises the following steps: adding a complexing agent into the sediments, and carrying out complexing reaction, thereby obtaining complex; and centrifuging, taking out supernatant liquor, adding ion liquid, oscillating, centrifuging, and taking sedimentary facies at the bottom, i.e., extracts containing rich mercury compounds. The extraction method utilizes the ion liquid to extract the mercury compounds in the sediments, so that the extraction effect is good, the enrichment multiple is high, and the extraction method is simple, fast and environmental-friendly. The invention also provides a detection method for the mercury compounds in the sediments. According to the detection method, pretreatment is carried out on the sediments according to the extraction method provided by the invention, and then the obtained extracts are detected by combined use of high-performance liquid chromatography and cold atomic fluorescence spectrometry. The detection method has the advantages of fastness, accuracy, stability, sensitivity and the like and is applicable to daily environmental monitoring.

The present invention relates to the technical field of dosing, in particular to a vertical high-precision powder dosing device with three-axis movement; the dosing device is suitable for the industryof fine chemicals, and the industry of new energy, food and medicine, and includes a frame; a material storage bin is arranged above the frame; a feeding port is arranged at the top of the material storage bin; a discharging port is arranged at the bottom of the material storage bin; the frame close to the discharging port is provided with a door opening and closing mechanism for closing or opening the discharging port; a blanking unit for outputting materials is arranged in the material storage bin; a conveying unit used for conveying a container to the discharging port of the material storage bin is arranged below the material storage bin; a conveying platform used for bearing the conveying unit is arranged on the frame; and a moving jacking unit used for jacking and moving the entire conveying unit from the conveying platform is arranged below the conveying unit. The dosing device of the present invention adopts an internal vertical spiral feeding mode and is combined with an external double-shaft mode of stirring and arch breaking, and the internal and external double shafts are respectively driven by double motors, and thus the structure of the dosing device is independent.

The invention discloses a preparation method of a carbon nanotube fiber loaded nano iron oxide composite material. The method comprises the following steps of (1) dissolving ferrocene in an organic solvent to prepare a ferrocene solution; (2) carrying out film drawing on a carbon nanotube array by adopting an array spinning method to form a carbon nanotube film, twisting the carbon nanotube film to prepare carbon nanotube fibers, and spraying the ferrocene solution obtained in the step (1) on the surface of the formed carbon nanotube film in the film drawing process; and (3) performing Joule heat treatment on the carbon nanotube fibers prepared in the step (2) in a protective atmosphere. The carbon nanotube fiber loaded nano iron oxide composite material prepared by the method has a good application prospect in the fields of preparation of capacitors, catalysis, electrode materials and the like.

A counter bearing for machining spindles of machine tools has at least one expansion bushing with an elastically deformable wall that delimits at least one pressure chamber. The pressure chamber accommodates a pressure medium. A supply line for the pressure medium opens into the pressure chamber. A pressure conduit opens into the pressure chamber. A mechanically actuatable pressure element is disposed in the pressure conduit and actuated by an actuating tool. A piston is slidably arranged in the pressure conduit and actuated by the pressure element, wherein the piston loads the pressure medium.
