IPC: H01H50/38
Filed: 2022-02-08
Abstract: The present disclosure provides a high-voltage direct-current relay with a magnetic steel arc extinguishing function, comprising two static contact leading-out ends and a movable contact spring. The movable contact spring is arranged below the two static contact leading-out ends, and two ends of the movable contact spring are correspondingly matched with bottom ends of the two static contact leading-out ends, respectively. First magnetic steels are respectively arranged at the periphery of the movable contact spring corresponding to the contacts, and the side having polarity of each first magnetic steel faces the corresponding contact. In the two static contact leading-out ends, a third magnetic steel is also arranged on the side opposite to the static contact, the side having polarity of the third magnetic steel faces the corresponding contact, and the polarity of the side of the third magnetic steel facing the contact is opposite to the polarity of the side of the first magnetic steel facing the contact. According to the present invention, the magnetic field strength of the contact point can be strengthened, such that the Lorentz force of the arcing point is always towards the arc extinguishing direction, thereby improving the arc extinguishing effect.

Title: Detachable carpet
Inventor: CAO SHUNLIN

Abstract: The present invention relates to a detachable carpet. The detachable carpet provided by the present invention includes a carpet surface layer and an adhesive anti-skid layer, wherein the carpet surface layer and the adhesive anti-skid layer are detachably connected. The carpet surface layer includes a surface layer and a sticky layer, wherein the surface layer is arranged at a top end of the carpet surface layer. Bent protruded monofilaments are distributed on a lower surface of the sticky layer, and there are lumps formed after the monofilaments are melted/softened at the tops of the monofilaments. The adhesive anti-skid layer includes a hooking surface layer and an anti-skid layer, wherein the anti-skid layer is arranged at a bottom of the adhesive anti-skid layer. After thermal treatment of the protruded monofilaments on the lower surface of the sticky layer, the top ends of the protruded monofilaments are melted/softened to form small lumps. Meanwhile, the monofilaments subjected to thermal treatment have certain radian and inclination to form hooked spines which can be hooked with various adhesive anti-skid layers therebelow to gain a locking effect. Thanks to a stronger bonding effect of the bent protruded monofilaments with the lumps, upper and lower layers can be separated with a larger tensile force, and meanwhile, the carpet surface layer will not displace due to a larger transverse frictional force, so that the detachable carpet features higher safety.

Abstract: The invention describes a method and a means for supplying nozzles comprising concentric pipes with gaseous and/or liquid hydrocarbons in which oxygen or oxygen-containing gases are simultaneously introduced into a converter. In so doing, the gases and/or liquid hydrocarbons are conducted through collecting pipes leading into distribution chambers. They are conducted from the distribution chambers through hydrocarbon volume control devices, which are integrally arranged along with the hydrocarbon distribution devices in a rotatable device element of the rotatable control unit, on to nozzle pipes. Then, the gaseous hydrocarbons are further conducted through a safety control member arranged downstream from the hydrocarbon volume control device. Thus, the even supply of gaseous and/or liquid hydrocarbons to the nozzles is ensured at highly varying throughput rates and alternate supply, in a manner which is simple and reliable.

Abstract: A method of recovering fluorine, e.g. as hydrogen fluoride, from wastes of aluminum electrolysis furnaces, chemisorbents, adsorbents or absorbents, etc. in which the fluorine-containing material is subjected to pyrohydrolysis in an expanded fluid bed and the HF-containing gas is subjected to condensation or scrubbing for the removal of the HF therefrom. According to the invention, the exhaust gases from the fluidized bed are cooled by direct contact with solids which can be circulated in a separate cycle and are themselves cooled in a cooler, e.g. by contact with gas which is to be fed to the expanded fluidized bed. The circulated solids thus allow recovery of the sensible heat of the gas without diluting it.
