摘要:
A device for measuring a mass of a body, the device including a support suitable for supporting the body, a frame and an actuator designed to vibrate the support relative to the frame. The device includes an accelerometer designed to measure values of an acceleration of the support upon vibration of the support, and an electronic control module designed to estimate the mass of the support body from the measured acceleration values.

A feed center for powder coating material includes a hopper, an extraction duct, and a control valve. The hopper is connectable in fluid communication with a fluidizing pressure source. The extraction duct is connectable in fluid communication with at least one suction source. The control valve connects the extraction duct with an extraction port of the hopper. The control valve is operable between a first position for applying suction from the at least one suction source to the hopper, and a second position providing an exterior opening in at least one of the control valve and the first extraction duct for exhausting pressurized fluid from the hopper and/or collecting at least some of the air and powder that is exhausted from the powder.

A composite structure formation method includes the steps of storing a plurality of pre-formed controlled particles in a storage mechanism, supplying the controlled particles from the storage mechanism to an aerosolation mechanism constantly, disaggregating the supplied controlled particles into a plurality of the fine particles in the aerosolation mechanism to form an aerosol in which an entire contents of the controlled particles including the fine particles are dispersed in the gas; and spraying all of the fine particles in the aerosol toward the substrate to form a composite structure of the structure and the substrate. The controlled particles are controlled so that bonding strength between the fine particles includes a mean compressive fracture strength sufficient to substantially avoid disaggregation during the supply step, but which permits the controlled particles to be substantially completely disaggregated in the disaggregation step.

The invention relates to a screen insert (70) for a powder container (24) of a powder supplying device, the screen insert (70) having a screen unit (71) for screening coating powder and an ultrasonic transducer (72) for generating ultrasonic vibrations. The screen unit (71) is connected to the ultrasonic transducer (72) in such a way that the ultrasonic vibrations generated by the ultrasonic transducer (72) can be transferred to the screen unit (71). To allow a particularly compact construction of the screen insert (70) to be achieved, according to the invention a screen carrier (73) which can be placed onto the powder container (24) is provided, for holding the ultrasonic transducer (72), with the screen unit (71) connected thereto, in such a way that the screen unit (71) is arranged below the screen carrier (73), so that the screen unit (71) is inside a powder chamber (22), formed by the powder container (24), when the screen carrier (73) has been placed onto the powder container (24).
摘要:
A powder fluidizing system, comprising a pressure vessel, a powder container removably mounted within the pressure vessel, and comprising a bottom sieve; a vibrator generating vibrations and transmitting the vibrations to the powder container above the sieve; and a guide directly secured under said powder container to the bottom sieve; wherein a bulk powder fed within the powder container is vibrated within the powder container and flows through the sieve to the guide, and a powder fluidizing method, comprising feeding a bulk powder within a powder reservoir maintained under pressure; vibrating the powder reservoir; and passing the powder through a sieve positioned at the bottom of the powder reservoir.
摘要:
A plurality of pre-formed controlled particles for use in 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. Each of the controlled particles includes an assembly packed with a plurality of fine particles which are not chemically bonded together, which include the brittle material fine particles, and have a mean primary particle diameter of 0.1 μm or more and 5 μm or less. The controlled particles have a mean circle-equivalent diameter of 20 μm or more.
摘要:
An arrangement for transporting powder comprises a hopper. The hopper is arranged on a stand and it has an inlet for receiving powder as well as an outlet for dispensing powder. A vibrator is attached to the hopper and the hopper is suspended to the stand via spring means.
摘要:
The invention relates to a device and a method for conveying powder. A container is provided for the powder, where the powder defines a surface in the container. A suction means has a suction opening for sucking in the powder from the surface. A moving means serves for producing a relative movement between the suction opening and the surface of the powder. During the relative movement, the powder is sucked in, a speed of the relative movement being variable in such a way that there is a constant mass flow.

A system and apparatus for preparing bulk quantities of dry colorant or pigment for blending with mortar are described. The system mixes pigments of black, red, white and yellow to prepare a batch of the dry colorant having a particular color. The pigments or dry colorant are generally a powder of metal oxide crystals. The system includes pigment dispensers, wherein each pigment dispenser includes a tote that is in flowing communication with a valve. A receptacle receives pigments from the exit opening of the vibratory trays. A control unit serially operates the vibratory trays to dispense the pigment from each tote. A scale measures the weight of the pigments in the receptacle. The scale is in operational communication with the control unit.
