The present invention provides a preparation method of a material for a puncture-resistant artificial blood vessel. The artificial blood vessel prepared by the method comprises two layers: the dense outer layer and the electrospun inner layer, the structures of these two layers are combined tightly and are inseparable, so that the properties of blood oozing resistance and repeated puncture resistance required by the artificial blood vessel can be provided. The puncture-resistant artificial blood vessel provided by the present invention has excellent biocompatibility, blood compatibility and flexibility and has the functions of blood oozing resistance and repeated puncture resistance. The method provided by the present invention has the characteristics such as convenience in operation, simplicity in production process and liability to the realization of large scale.

The invention relates to a coating arrangement for coating particles, a method for coating particles, and corresponding uses. The coating arrangement includes a coating chamber and a coating device arranged in the coating chamber. This device comprises a hollow body with an axis, the inner wall of which forms a particle track around the axis of the hollow body, a particle source and a particle sink, and at least one coating source. The coating source is adapted for emitting a coating material along a direction perpendicular to the axis of the hollow body. Furthermore, the coating device comprises a rotation device which is adapted for rotating the hollow body about its axis, and a cleaning device which is arranged in the interior of the hollow body in a stationary manner with respect to the hollow body and is adapted for removing adhering coating material from the inner wall of the hollow body.

The present invention relates to a method for producing water-insoluble quantum dot patterns on and/or within a substrate. The method comprises a step of depositing a deliquescent salt, quantum dots and an acid or salt thereof onto at least one surface region of a substrate such that the deliquescent salt, the quantum dots and the acid or salt thereof are at least partially contacted to form said at least one water-insoluble pattern.

A varnish injection system includes a varnish injector including a base, a nozzle extending from the base, and a spacer disposed on the nozzle, and an electric motor including a stator, a wire, and an insulating layer between the stator and the wire. The nozzle is arranged to deposit varnish between the stator and the insulating layer. The nozzle and the stator define a gap therebetween when the spacer engages the stator.

A method for applying a predetermined pattern of material onto an elongate tubular substrate includes securing a first portion of an elongate tube having a non-circular outer perimeter to an engagement member configured to be rotated by a first motor, such that the elongate tube can be rotated in unison with the engagement member, operating the first motor to rotate the elongate tube, operating a second motor of to change the relative displacement between the elongate tube and a dispensing conduit along a longitudinal axis of the elongate tube, and expelling a conductive adhesive from a fluid dispenser through the dispensing conduit to form a predetermined pattern of the conductive adhesive on a surface of the elongate tube, the predetermined pattern of the conductive adhesive covering at least 180 degrees of the surface along the non-circular outer perimeter over a width of at least two millimeters along the longitudinal axis.

A post-cure inflation machine for processing a tire may include a tire holder shaft. The tire holder shaft may include a chuck to secure the tire to the tire holder shaft. A hollow passage may be defined in the tire holder shaft. A spray nozzle may be connected to a spray shaft that is telescopically disposed in the hollow passage of the tire holder shaft. The spray nozzle may extend to spray an air barrier material onto the tire.

A method for coating a monolithic porous catalyst support having a plurality of channels formed in a longitudinal direction with a catalyst slurry, and a device therefor are proposed. A pressure dispersion coating device for a porous catalyst support includes: a slurry quantitative input means; a container being variable in volume, having an open upper part thereof into which a slurry is input by the slurry quantitative input means, and having a bottom thereof movable; a container moving means fastened to one side of the container; a moving means fastened to a lower part of the container and having a shaft connected to the bottom of the container; an overflow outlet being formed on a side part of the container and provided with a valve; and a pressurizing means disposed on the open upper part of the container.

The invention relates to an apparatus for the vapor deposition of a coating on optical articles, comprising a distribution mask (32) for controlling the vapor deposition of a coating on optical articles that is positioned in the path of some of the molecules emitted by said emitting source in the direction of the rotatable support for optical articles. The distribution mask (32) is fitted with at least one arm (34) positioned so as to mask at least one partial zone (16) of an individual housing (28) on a portion of the revolution turn, this masked partial zone (16) comprising the center of the individual housing (28).
