Movement of the impeller means relative to the wall portion is achieved by making the impeller means flexible. A vibrator (6) may be provided to cause movement of the impeller means. The characteristics of the components can be chosen so that when the vibrator is activated the impeller vibrate...
SURGICAL NEEDLE WITH WEEPING TIP AND METHOD OF USE The invention provides surgical needles with a porous distal portion from which a liquid injectate will weep or ooze multidirectionally under injection pressure while the porous distal portion of the needle is inserted into a body surfac... VAN...
a top plate opposing to the substrate and including the restricting portion, and the liquid is discharged from the discharge part by an energy during generation of the bubble, in which the clearance between at least one sidewall of the flow path and the side edge portion of the restricting ...
(57)< Abstract > The manner which carries the solid-state material piece in the liquid of the mass arrangement for interchanging includes the fact that air impulse of the indentation which is converted to the mutual motion of the liquid is formed. This motion is directed, in order to make...
of the melt and the reinforcements involved in it are researched systematically in the electromagnetic field. The physical mechanism and principles of the nonmetallic particles movement in the metal liquid are established and the physical model and dynastic functions are obtained. The influences of the...
This invention relates to a pumping apparatus operable incidental to movement of liquid in flow line systems; for example, the discharge of liquid from a liquid and gas separating system, the principal object of the present invention being to provide a pumping apparatus of this character adapted....

As the Critical Heat Flux (CHF) condition is approached, a thin layer of vapor begins to form between the heated surface and the liquid. The mechanisms leading to the formation of this interface are not clearly understood. The present investigation focuses on obtaining high-speed video images of...
Date Nov. 26, 1992A writing utensil has a container with an opening for receiving a writing liquid and a writing tip. An at least partially capillary conveying line is provided and connected between the opening of the container and the writing tip for conveying the writing liquid from the ...
A method of and an apparatus for determining the relative direction and velocity of movement between an object and a fluid stream (either gas or liquid) using the Karman vortex phenomena is disclosed. In one form, two omnidirectional rin... JOY R,COTTON R - US 被引量: 14发表: 1974年 Th...
