Abstract:
A composite structure formation method based on an aerosol deposition method by which an aerosol with brittle material fine particles dispersed in a gas is sprayed toward a substrate to form a structure made of the brittle material fine particles, the composite structure formation method includes: storing a plurality of controlled particles in a storage mechanism, the controlled particle being an assembly packed with a plurality of particles including the brittle material fine particles; supplying the controlled particles from the storage mechanism to an aerosolation mechanism; disaggregating the supplied controlled particles in the aerosolation mechanism to form an aerosol; and spraying the aerosol toward the substrate to form a composite structure having the structure and the substrate.
Abstract:
The present invention is directed to a cremated remains spreading device that includes a hopper for holding the cremated remains having a conduit attached to the hopper. A blower assembly including a blower and motor is connected to a first end of the conduit for providing a pressurized air flow through the conduit. The hopper is adapted to deposit the cremated remains into the pressurized air flow in the conduit, the cremated remains being discharged from an outlet port formed at a second end of the conduit.
Abstract:
A capsule dusting system is designed to expose capsules to a dusting agent in a controlled manner. The system incorporates a tumbling basket positioned within an enclosure. The tumbling basket is loaded with capsules and is rotatably connected to a drive shaft. A dust injection system meters the dusting agent into the dust injection system. The dust injection system may include a dusting injector that translates between two positions. At one position, the dusting injector is loaded with dusting agent by a powder supply system. At the other position, the dusting injector is positioned to inject the dusting agent into the tumbling basket. A gas is fluidly connected to the dusting injector to cause the dusting agent to disperse into the tumbling basket. The enclosure contains the dusting agent within the system to reduce the environmental, health, and safety hazards associated with airborne particulates.
Abstract:
A method and apparatus for coating a product is provided, the method comprising delivering the product to a top end of an inclined chute, the chute comprising at least one mesh portion provided in its conveying surface; allowing the product to fall along the conveying surface; and when the product passes over the at least one mesh portion during its fall, spraying the product with a coating.
Abstract:
A central powder supply system, referred to as a so-called powder center (1) is made available for use especially in high-performance industrial powder coating installations. The powder center (1) is divided into two separate chambers (2, 3), an operating chamber (2) and a powder chamber (3). Both chambers (2, 3) can be connected with a powder separating device via an opening which can be closed off. The powder chamber (3) essentially houses the powder preparation device (5), while the operating chamber (2) contain the operating parts (22) and supply parts (20, 21). The powder preparation device (5) comprises a height-adjustable lifting table (7) with vibration device for the powder supply container (6 positioned thereon. In addition, there is a suction plate (12) which serves as suction device and has through openings (13). The suction plate (12) is surrounded by a strain basket (17) which, optionally, has a support basket (18). Provided at a distance thereto is a fluidizing device (14) which is configured in a basket-like manner and in which the strain basket (17) and, optionally, the support basket (18) are arranged one inside the other. The powder center permits a rapid and substantially automatic cleaning during change of powder.
Abstract:
The invention relates to a powder-fluidizing and feeding device for use with coating and spray forming nozzles and guns. The device includes novel provisions for controlling and feeding powder from a hopper to a vibrating bowl, for heating and vibrating powders in the hopper to dissipate agglomeration and clumping of the powder, and for metering powders from a vibrating bowl to the spray nozzles and guns using a feedback control derived from powder mass loss rate measurements. The device is particularly useful for feeding ultra-fine and nanoscale particles, which are difficult to feed uniformly with the prior art of conventional powder feeders.
Abstract:
An apparatus and method for the aerosolization of powders is disclosed. The invention includes a chamber in which a cloud of aerosolized powder is formed, the cloud having a relatively even distribution of powder particles. A Bernoulli tube may be used to extract powder from the powder cloud when the powder cloud reaches its equilibrium height. Adjustment of the air flow rate into the Bernoulli tube may be used to control the flow rate of powder out of the disclosed device.
Abstract:
A nozzle apparatus and method for dispensing powdered material from a container such as a cardboard shipping box. The apparatus has a shaft with a tip in the shape of a slant-cut cylinder which is manually inserted into the container through the container wall and an inner plastic lining of the container. A threaded portion on the shaft in the form of an increasing radius helix thread causes the apparatus to tighten against the wall of the container when the user manually rotates a gripping portion of the apparatus. A passageway extends from the tip to a fitting outside the container which can be connected to a vacuum source such as a powder pump to draw in the powder coating material. The fluidized powder is then carried to a spray gun for powder coating an object. A second passageway may be carried within the shaft and extend from an opening within the container to a fitting outside the container to carry a pressurized gas into the container. The container may be placed on a vibrating tilted platform to agitate the powder coating material.
Abstract:
A surface processing method by blowing submicron particles is disclosed, in which submicron particles are blown against a surface of a work to deposit a layer of the material of the particles on a surface of the work, or etching the surface of the work.The processing method uses blowing air stream containing submicron particles having average particles size ranging between 0.01 and 3.0 .mu.m. The deposition or etching is effected depending on an incident angle of the particles to the surface of work. According to the method deposition of the material can be effected with very high deposition rate and in case of etching very smooth etched surface is obtained.
