Abstract:
This document describes a process and a device for applying fluids, specifically particle material, on an area to be coated, which is viewed in forward moving direction of the coater, chat fluid is applied on the area to be coated and then a levelling element is run over the applied fluid, whereby the fluid is led from a metering system provided with an opening, which oscillates when applying the fluid. The opening shall be designed in such a way that when the metering system is at a standstill this is closed by forming an angle of repose of the fluid.
Abstract:
An apparatus (100) for applying a substance (200) as a bead (202) to a geometric feature (204) extending along a path (220) is disclosed. The apparatus (100) comprises an outlet end (101) comprising a first edge (104), a second edge (106), and an outlet opening (102) at least partially defined by the first edge (104) and the second edge (106). The first edge (104) and the second edge (106) are reversibly extensible.
Abstract:
Disclosed is coated paper having a coating structure in which styrene-butadiene latex distribution of a paper coating layer is controlled in order to reduce fold cracking of the coated paper and a method for manufacturing the same. The coated paper in which different types of latexes are separately applied to two coating layers exhibits considerably improved stiffness and reduced fold crack, as compared to the existing coated paper.
Abstract:
A fluid applicator for applying a fluid to a surface protrusion. In one embodiment, an anticorrosion substance is applied to a structural fastener.
Abstract:
A slit nozzle of a liquid coating apparatus which discharges a liquid on a substrate, the slit nozzle includes a first nozzle part, a shim having an outlet configured to discharge the liquid and a second nozzle part facing the first nozzle part with the shim interposed therebetween. At least one of the first nozzle part and the second nozzle part has a sloping portion to prevent the discharged liquid from adhering to the slit nozzle.
Abstract:
Provided is a triboelectric pressure sensing cable. The triboelectric pressure sensing cable comprises a central conducting wire, a high-molecular polymer insulating layer, an electrode layer, and an insulating outer layer, which are coaxially attached in sequence. The central conducting wire and the high-molecular polymer insulating layer, and/or the high-molecular polymer insulating layer and the electrode layer separately generate signals by the means of triboelectric effect. Also provided is a method for preparing the triboelectric pressure sensing cable. The method comprises the steps of (1) preparing a high-molecular polymer solution; (2) forming a hollow cavity framework used for casting; (3) casting; (4) molding; and (5) forming an insulating outer layer so as to obtain the triboelectric pressure sensing cable. The provided triboelectric pressure sensing cable can achieve a monitoring effect which is the same as that of a conventional pressure cable, without requiring a high input impedance circuit or a charge-amplifier.
Abstract:
A compound delivery applicator comprising a substantially conical portion comprising a first end configured to couple to a compound receptacle and an applicator blade comprising a first portion extending outwardly along a longitudinal axis of and from a second end of the substantially conical portion, the first portion comprising a first side edge and a second side edge each forming an acute angle relative to the longitudinal axis of the substantially conical portion and a scraper comprising a recessed channel along an edge of the scraper. The device further comprises a substantially cylindrical hollow compound delivery channel extending along the longitudinal axis of and internally through at least a portion of the substantially conical portion, the substantially cylindrical hollow compound delivery channel further extending through the scraper of the applicator blade and configured to pass a compound therethrough and a flow control button located within the recessed channel.
Abstract:
A method to fabricate hierarchical graded materials includes providing a reservoir of functionalized particles, mixing at least some of the functionalized particles using a mixer in the print head having a mixed fluid volume control on an order of a voxel to produce mixed functionalized particles, and actuating a print head to deposit the mixed functionalized particles on a substrate.
Abstract:
A method for depositing particles on a substrate, or a running substrate, including: (a) producing at least one first compact film of particles floating on a carrier liquid provided in a transfer area having an outlet of particles arranged facing the substrate; (b) producing at least one pattern by depositing a substance on the first film in the transfer area, along a contour of the pattern, the substance maintaining the particles of the film together in contact with the substance; (c) removing at least one portion of the particles of the first film located interiorly relatively to the contour, or exteriorly relatively to the contour; and then (d) transferring patterns onto the substrate through the outlet of particles.
Abstract:
It has now been determined that a first coating layer may be applied to a substrate by a first coating die in a much thinner layer than its rheological properties and/or surface properties would normally allow. This is accomplished by using a second coating fluid dispensed from a second coating die acting as a “dynamic liquid squeegee” to transport, spread, even, or meter the first coating layer on the substrate by varying a gap between the second coating die and the substrate.
