An apparatus includes a housing, a crucible disposed in the housing, and a collection bin. A turnplate disposed in a powder collection area is of an inlaid structure. A concentric circular groove is provided on the atomization plane. An air hole is provided in the turnplate. The present invention combines the pulsated orifice ejection method and the centrifugal atomization method, in cooperation with the turnplate structure and subjecting the turnplate surface to induction heating, so that a metal liquid is allowed to break through the split mode of traditional molten metal, achieves a fibrous split mode that can be implemented only when an atomizing medium is an aqueous or organic solution, and prepares a high-melting-point metal powder that meets requirements, and has a controllable particle size, high sphericity, no satellite droplets, and good flowability and spreadability, and is suitable for industrial production.

An apparatus efficiently preparing ultrafine spherical metal powder includes a housing, a crucible and a powder collection area arranged in the housing. The turnplate arranged in the powder collection area is an inlaid structure. The part inlaid into the body part acts as an atomization plane of the turnplate. The atomization plane is provided with a concentric circular groove, and the turnplate is provided with an air hole. The apparatus is used for preparing ultrafine spherical metal powder by on-by-one droplets centrifugal atomization method, mainly combining the uniform droplet jet method and the centrifugal atomization method, which breaks through the traditional metal splitting model, makes the molten metal in a fibrous splitting, so as to efficiently prepare ultrafine spherical metal powder with narrow particle size distribution interval, high sphericity, good flowability, excellent spreadability, uniform and controllable size, no satellite droplets and suitable for industrial production.

The present invention has provided a method for live broadcasting in distributed network and means for the same. Wherein the method mainly comprises steps of: tracker servers receive the status report information from the program source connected to the tracker server; generates the status information of the program source based on said status report information; sends status information of the program source to the information synchronization means.
摘要:
An apparatus for efficiently preparing spherical metal powder for 3D printing includes a housing, a crucible and a powder collection area arranged in the housing, wherein a turnplate arranged in the collection area is an inlaid structure. A material having a poor thermal conductivity is selected as the base of the turnplate, and a metal material having a wetting angle less than 90° with respect to droplets is selected and embedded into the base to serve as an atomization plane of the turnplate. An air hole is disposed in the turnplate. The spherical metal powder for 3D printing combines electromagnetic force breaking capillary jet flow and centrifugal atomization, which breaks through the traditional metal split mode, and makes the molten metal in a fibrous splitting.

In one embodiment, a modular dissolution-testing apparatus has a base unit adapted to hold and control operation of between one and eight dissolution-testing modules. The base unit has a programmable controller and a color touch screen for user interface with the controller and the modules. Each module includes a vessel for holding a solution of a dosage form dissolving in a solvent, an agitator apparatus for stifling the solution, and a motor to power—via a multi-motion assembly and a stifling shaft—stifling by, lifting of, and lowering of, the apparatus. Each module has a vessel heater and a temperature sensor, both communicatively connected to the controller for heating and regulating the temperature of the vessel contents. Each module is independently controllable by the controller, where control includes manually (by a user) or programmatically setting stifling speed, lifting and lowering apparatus, and starting and stopping stirring and heating.

A device, method and system are provided to continuously store and analyze single or multi-lead ambulatory ECG signals. Each ECG device is self-contained, wire-free, reusable and capable of non-invasive continuous recording, analyzing and indexing of ECG data independently. A pair of snap connectors on the device body attaches the device to standard ECG electrodes to minimize noise caused by the wires. Each device contains a real-time clock to link the ECG data and a detected cardiac event with actual date and time. The device contains a USB port to upload the data to a host system. Multiple such devices are wearable by a patient to form a multi-lead ECG system. There is provided a method to continuously record and analyze ECG data using a self-contained, wire-free ECG device or multiple such devices; and further a method to synchronize the ECG data in multiple devices to realize multi-lead ECG recording.
