The average particle size and its distribution are undoubtedly major characteristics of a powder, and the average particle size occurs in all correlations related to the powder behaviour in, e.g., packed, moving or fluidized beds, in pneumatic conveying and in dust filtration. When traditional sieving can no longer be used for smaller particles, instrumental techniques, i.e. particle size analy...

The future More Electric Aircraft (MEA) technology focus on increasing the use of electrical equipment to a larger extent, e.g. replacing conventional hydraulic and pneumatic actuators with electromechanical or electro hydrostatic actuators to reduce weight, cost and maintenance. Advances in enabling technologies of electric power generation, distribution, and utility equipment have made the us...

among the therapeutic options for achalasia are pneumatic dilatation (pd), an appropriate long-term therapy, and botulinum toxin injection (bt) that is a relatively short-term therapy. this study aimed to compare therapeutic effect of repetitive pneumatic dilation with a combined method (botulinum toxin injection and pneumatic dilation) in a group of achalasia patients who are low responder to ...

One of the possible ways to increase efficiency cleaning separation could be grain fortification heap feeding chaffer sieve and intensification sifting through this sieve. This direction makes it develop air-sieve with pneumatic inertia separator for high-producing combine harvester. Cleaning improvement will provide agricultural production equipment higher agrotechnical capabilities lower mate...

Among the power drills (Electrical/Pneumatic/Battery) used in Orthopedic surgery, battery drill has got several advantages. Surgeons in low resource settings could not routinely use Orthopedic battery drills (OBD) due to the prohibitive cost of good drills or poor quality of other drills. "Hardware" or Engineering battery drill (HBD) is a viable alternative to OBD. HBD is easy to procure, rugge...

Ocean wave is one of the renewable energy resources that these days various devices are used to extract its energy. Oscillating Water Column (OWC) installed on the shore is one of the wave energy absorption systems which has received attention due to its simple structure. Investigation of the pneumatic power is of great importance in such systems as the conversion of wave energy to pneumatic en...

Abstract The paper presents a new universal programmable portable measuring device (PMD) intended for the diagnostic and monitoring of hydraulic pneumatic equipment. PMD offers simple, complete, efficient remote solution is designed measurement, recording, processing data as well graphical visualization registered results on test stand or in operating site to measure parameters used servicing, ...

New pneumatic actuators developed in the author's laboratory will be presented with their applications to new mechatronics. Examples of them are a pneumatic rubber actuator for compliant robots, a micro pneumatic tube actuator assisting the colonscope insertion, a pneumatic stepping motor with high torque and resolution, a pneumatic drive bicycle, an intelligent pneumatic cylinder which has enc...
