Abstract:
Apparatus for conveying elongated objects of small diameter. After an object is coated with a protective coating, a first conveyor flight having a generally V-shaped groove receives the leading end of the object. A second conveyor flight has a generally U-shaped groove to be positioned in alignment with the object for receiving it if additional support is necessary, although generally remaining out of contact with the object. Another one of the aforedescribed first conveyor flights follows each of the aforedescribed second conveyor flights so that both ends of the object are normally supported by one of the first conveyor flights. In the event either end of the object misses one of the moving first conveyor flights, an adjacent second conveyor flight will receive the object and support it for movement. In a modified form of the invention the second conveyor flight having the U-shaped groove is eliminated and a second flight having a V-shaped groove which is removably inserted into the conveyor is utilized if needed.
Abstract:
A powder supplying device (2) includes a case (6) in which a storage portion (6a) is formed for temporarily storing powder (10), the case (6) having an inlet (6b) formed in an upper end of the storage portion (6a), and a rectangular outlet (6c) formed in a lower end of the storage portion (6a); a rotor (7) that is arranged in the case (6) and transports the powder (10) in the storage portion (6a) to the outlet (6c) by rotating; and a mesh body (8) through which the powder (10) that has been transported to the outlet (6c) passes. The powder supplying device (2) supplies the powder (10) onto an upper surface of an electrode foil (5). The rotor (7) has a brush-like shape, with a plurality of hair members (7b) radially implanted pointing radially outward with an axial center (G) of the rotor (7) as the center.
Abstract:
Systems and methods for magnetically autonomously clamping a downhole component in a select direction of a borehole casing. The systems can include a sensor package that obtains a downhole measurement in a position in a cased borehole. The systems can include an integral magnetic clamp that removably clamps the downhole component (e.g., a downhole seismic shuttle) to the cased borehole. The systems can include a directional detector that outputs a select direction of the cased borehole relative to the downhole component. The systems can include a downhole controller that activates a portion of the integral magnetic clamp of the downhole component closest to the select direction output by the directional detector.
Abstract:
Apparatus and method for electrostatic charging of a container for an electrostatic coating operation includes a support member for supporting a container during an electrostatic coating operation with the support member comprising a non-metallic conductive material or electrically semiconductive portion that directly contacts a surface of the container. The electrically semiconductive portion comprises non-metallic, resistive or low conductivity material and is coupled to a source of electrical energy such that the container is electrostatically charged to an opposite polarity to offset or reduce electrostatic charge build up produced by the electrostatic coating operation.
Abstract:
A coating device includes a shell, a plurality of shaft groups, a plurality of first bases, a second base, and a driving device. The shell defines a coating chamber. The shaft groups are parallelly arranged in a first circle and housed in the coating chamber. Each shaft group includes a plurality of holding shafts parallelly arranged in a second circle and configured for holding workpieces. The first bases are housed in the coating chamber and surround the shaft groups. The second base is housed in the coating chamber and surrounded by the shaft groups. The first and second bases are configured for receiving targets. The driving device is configured for driving each holding shaft to spin.
Abstract:
An electrospraying apparatus and/or method is used to coat particles. For example, a flow including at least one liquid suspension may be provided through at least one opening at a spray dispenser end. The flow includes at least particles and a coating material. A spray of microdroplets suspending at least the particles is established forward of the spray dispenser end by creating a nonuniform electrical field between the spray dispenser end and an electrode electrically isolated therefrom. The particles are coated with at least a portion of the coating material as the microdroplet evaporates. For example, the suspension may include biological material particles.
