New designs of valves for storage tanks
Chemical and Petroleum Engineering, 1987Fire protection measures applied to KD type breather valves for crude oil and petroleum product storage tanks have resulted in increasing the valve metal content and in difficulties in their production and operation. Three new valves, designated KSD-50, KSD-150, and KDS-1000, were developed by the Ufa Branch of the All-Union Research of Petroleum ...

New stent design for percutaneous aortic valve replacement
Cardiovascular Revascularization Medicine, 2009Vascular support structures are an important tool for treating valve stenosis. A large population of patients are treated for valvular disease and the principal mode of treatment is the use of percutaneous valvuloplasty. Stent devices are proving to be an improved treatment method; these devices now account for 20% of treatments in Europe.

T-Pouch: A New Valve Design for a Continent Ileostomy
Diseases of the Colon & Rectum, 2002After proctocolectomy for ulcerative colitis or familial adenomatous polyposis, creation of a continent ileostomy is one of the surgical options. Although most patients will be offered a pull-through procedure, the continent ileostomy is a valuable alternative in patients who are either not candidates for or have failed an ileal pouch-anal anastomosis ...

Design and Experiments of a New Type Pressure Proportional Valve
2018 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM), 2018In this study, a new type nozzle-flapper pressure proportional valve driven by a voice coil motor is designed. In order to improve the dynamic response of pressure proportional valve, a voice coil motor (VCM) with high response speed is used to drive the flapper.

Elastomeric valves, a new design.
The International journal of artificial organs, 1996The convex bileaflet valve replaces the flat biflap inflow valve designed by Long Sheng Yu and the tricusp semilunair outflow valve. One reason is easier manufacturing. Convex bileaflet valves are developed for the 11, 20, 40, 70 and 140cc ventricles.

New Valve and Bonding Designs for Microfluidic Biochips Containing Proteins
Analytical Chemistry, 2006Two major concerns in the design and fabrication of microfluidic biochips are protein binding on the channel surface and protein denaturing during device assembly. In this paper, we describe new methods to solve these problems. A "fishbone" microvalve design based on the concept of superhydrophobicity was developed to replace the capillary valve in ...
