Abstract:
The invention relates to a device for hot-dip coating a metal strand (1), especially a steel strip, in which the metal strand (1) is vertically guided through a container (3) accommodating the molten coating metal (2) and through a guide channel (4) disposed upstream thereof. The inventive device comprises at least two inductors (5) disposed at both sides of the metal strand (1) in the area of the guide channel (4) that are used to generate an electromagnetic field for retaining the coating metal (2) in the container (3), and at least one sensor (6, 6′) for detecting the position (s) of the metal strand (1) in the area of the guide channel (4). In order to simplify and render more precise the detection of the position of the metal strand in the guide channel, the sensor for detecting the position of the metal strand (1) consists of two coils (6, 6′) that are disposed, when seen from the direction of conveyance (R) of the metal strand (1), within the height (H0) of the inductors (5) between the inductors (5) and the metal strand (1). The invention further relates to a method for hot-dip coating a metal strand.
Abstract:
A process and system for continuous flow-through dip-coating of a workpiece requires the introduction of the workpiece in a porous coating basket at a first side of a coating chamber and the removal of the coated workpiece in the coating basket from a second side of the coating compartment different from the first side. This enables the commingling of coated and uncoated workpieces to be avoided and allows for a higher throughput in the coating process.
Abstract:
An electroless plating apparatus can form a protective film on exposed surfaces of embedded interconnects stably with good selectivity for thereby protecting the interconnects. The electroless plating apparatus includes a magnetic removal portion for magnetically removing small magnetic suspended solids in an electroless plating solution which have not been removed by a filter.
Abstract:
A container (50) for an apparatus for automated cryosubstitution or low-temperature substitution is disclosed. The container is embodied as a cup (51) open at the top. The container (50) is subdivided into a first sector (52) and a second sector (53), at least one specimen holder (2) being arranged in the first sector (52) and at least one reservoir holder (20) in the second sector (53); and the container is arranged in the neck of a Dewar vessel (1).
Abstract:
The disk lubricant tank of the present invention includes a lubricant bath cover device that resides on the lubricant bath surface to suppress surface waves. The bath cover includes a plurality of finger-like projecting members that define a plurality of disk passage slots therebetween. A plurality of disks are disposed upon a disk holding mandrel and are lowered into the lubricant bath. Each disk passes through a separate disk passage slot during the dipping process. The finger-like projections reside on the bath surface between the disk to suppress surface waves that would otherwise impinge upon side surfaces of the disk, leading to lubricant overcoat areas upon the side surfaces of the disk. Therefore, hard disks of the present invention are formed with a more uniform lubricant coating wherein unwanted lubricant overcoat areas formed by surface waves in the lubricant bath are suppressed.
Abstract:
The invention relates to a device for hot dip coating metal strands (1), particularly strip steel, in which the metal strand (1) can be vertically guided through a reservoir (3), which accommodates the molten coating metal (2), and though a guide channel (4) connected upstream therefrom. An electromagnetic inductor (5) is mounted in the area of the guide channel (4) and in order to retain the coating metal (2) inside the reservoir (3), can induce induction currents in the coating metal (2) by means of an electromagnetic blocking field. While interacting with the electromagnetic blocking field, said induction currents exert an electromagnetic force. In order to prevent an intense heating of the metal strand caused by the electromagnetic inductor, the invention provides that the inductor (5, 5a, 5b) is connected to electric power supply means (6) that supply the inductor with an alternating current whose frequency (f) is less than 500 Hz. In particular, a mains frequency of 50 Hz is intended.
Abstract:
A substrate processing apparatus has a processing tank (10) for plating a substrate (W) in a plating solution (Q) holds therein, a cover (40) for selectively opening and closing an opening (11) of the processing tank (10), a spraying nozzle (60) mounted on an upper surface of the cover (40), and a substrate head (80) for attracting a reverse side of the substrate (W) to hold the substrate (W). With the cover (40) removed from the opening (11) of the processing tank (10), the substrate head (80) is lowered to dip the substrate (W) in the plating solution (Q) for thereby plating the substrate (W). When the substrate head (80) is lifted and the opening (11) of the processing tank (10) is closed by the cover (40), the substrate (W) is cleaned by the spraying nozzle (60).
Abstract:
A machine for single or double sided application of a liquid or viscous coating medium by way of at least one applicator unit onto the surface of a mating material web, especially a paper or cardboard web. A medium collecting device that is allocated to the applicator unit or to a dispensing component of the applicator unit which includes the dispensing openings, is equipped with a receiving and release component which is allocated to the medium collecting device and which is or can be mounted detachably on same. During the start of the application process the component releases the curtain or veil due to a common adjustment with the medium collecting device or of a section component of same relative to the curtain or veil from a rim extending across the moving background or from an edge extending across the moving background.
Abstract:
The invention relates to a method of manufacturing a layer (7) over a surface (6) from a liquid or viscous plastic (8) which solidifies once the layer (7) is formed, characterized in that the plastic (8) is introduced in liquid or viscous form into a reservoir (2) of variable volume, at least part of the inner wall of which is defined by a portion of the said surface (6); the reservoir (2) and the surface (6) are moved relative to each other while simultaneously decreasing the volume of the reservoir (2) so as to compress the plastic (8) and make it flow through a passage (9) connecting two surface portions placed respectively inside and outside the reservoir (2), the rate of flow of the plastic (8) through the passage (9) being chosen so as to form a layer (7) over one of the said surface portions (6) whose thickness (e) is less than the height of the said passage (E). The invention also relates to a device using the method described above and to the objects obtained by this same method.
