Abstract:
A continuous dosage form coating apparatus uses vibrational impulses to maintain a dosage forms in a fluid state to expose them to a coating material atomized by spraying.
Abstract:
In a method for forming an adhesive layer on the surface of a workpiece before the formation of a coating film containing a powder on the workpiece, the present invention provides a method for forming the adhesive layer having a desired thickness. This object is achieved by the following method: An adhesive layer formation medium m1 coated with an adhesive material is made to collide with a workpiece W so that the adhesive material is transferred from the adhesive layer formation medium m1 to the workpiece W and forms an adhesive layer on the workpiece. An adhesive layer having a desired thickness can be formed on the workpiece by regulating the thickness of the adhesive material applied to the surface of the adhesive layer formation medium (i.e. the amount of the adhesive material held by a single adhesive layer formation medium). This enables the thickness of the powder coating as the final product to be controlled as desired.
Abstract:
Technologies are generally described to increase a surface smoothness of a 3D printed article implementing a water-based treatment using layer by layer (LBL) deposition. An initial 3D printed article having an anionic surface may be treated with a first aqueous solution comprising at least one polycation that may bind to the anionic surface to produce a first treated surface, which may be rinsed with water to remove the first aqueous solution. The first treated surface may be treated with a second aqueous solution comprising at least one anionic microparticle that may bind to the polycation to produce a final 3D printed article having. a second treated surface, which may be rinsed with water to remove the second aqueous solution. The bound polycation and anionic microparticle may be present as a single layer in the final 3D printed article that may act as a conformal coating to increase the surface smoothness.
Abstract:
A fiber processing system includes a fiber spreader that has a spreader bar that extends in a lengthwise direction between first and second ends. The spreader bar carries at least one radiused surface between the first and second ends. At least one mechanical vibration device is operable to vibrate the spreader bar. The at least one mechanical vibration device is connected to input mechanical vibration into the spreader bar at a location between the first and second ends. A method for spreading at least one fiber bundle includes moving at least one tensioned fiber bundle over a radiused surface of the spreader bar. During the moving, mechanical vibration is input into the spreader bar at a location between the first and second ends, to transversely spread and flatten the at least one tensioned fiber bundle.
Abstract:
The invention relates to a device for coating a product, comprising a unit for providing a liquid (2) that contains the reagents necessary for coating. The device further comprises a transport device (3), for bringing the surface of the product (4) to be coated in contact with the liquid and for passing it by the liquid such that the surface to be coated stays in contact with the liquid for a certain time in order to effect a coating thereof.
Abstract:
A magnetic lifting device for lifting a stack of specimen holders out of one tube and lowering them into another tube is disclosed. The device avoids the necessity of manual handling of the stack. ln the device there are a number of stack holding tubes, each one open at the top, positioned in a circle about a vertical axis of a rotatable carousel. An indexing system rotates the carousel to selectively place one of the stack holding tubes in a treatment position. The improvement comprises a magnetizable member attached to the top of the stack of sample holders, a transfer tube having a bottom opening positioned to mate on top of the stack holding tube to hold the magnetizable member in a magnetic field, a device to raise and lower the magnetic coil about the transfer tube to raise and lower the magnetic coil about the transfer tube to raise the stack into the transfer tube allowing the carousel to be rotated, and lower the stack into another stack holding tube.
