Abstract: ABSTRACT OF THE DISCLOSURE      A muffling device comprising an internally segmented main body narrowed at the body's ends with a widened midsection.  The interior of the body is divided by a series of bell shaped walls extending from the body's midsection to define a first outer chamber surrounding a second inner chamber within the body's upper half, a third chamber extending between the midsection of the body, and a fourth inner chamber surrounded by a fifth outer chamber within the body's lower half.  The first chamber communicates with the second chamber by an aperture in the wall separating the two chambers.  The second chamber communicates with the fourth chamber by a central passage extending from the second chamber through the third chamber and into the fourth chamber.  The fourth chamber communicates with the fifth chamber by an aperture in the wall separating the two chambers.  The main body has an inlet passage that communicates with the first and second chambers and an outlet passage that communicates with the fourth and fifth chambers.

Title: Method and apparatus for reduction of pressure in a liquid mixture
Inventor: KLINTENSTEDT KJELL
IPC: E21B43/00
Filed: 1987-11-27
Granted: 1991-12-24
Abstract: ABSTRACT A method and apparatus to reduce the pressure of crude oil from an oil well, i.e. a mixture of hydrocarbon compounds, which is conventionally performed stepwise, which a momentary pressure drop occuring at each stage. According to the invention, oil is caused to flow radially inward in a chamber, which is formed by a rotating vessel which is only partly filled with rotating oil, whereby the pressure drop in the oil can occur relatively slowly.  A free liquid surface is maintained in the chamber, and a certain gas pressure is maintained in the liquid free volume thereof, while evaporated hydrocarbon compounds are moved through a central gas outlet.  By means of a special inlet device an increase in oil pressure is prevented when flowing through a channel radially outward in the vessel to the level from which it is to flow radially inward, which increase would happen if the oil was allowed to flow freely in the channel and simultaneously be completely entrained in that oil rotating with the vessel.

Granted: 1992-08-18
Abstract: ABSTRACT OF THE DISCLOSURE            Air knife designed to be used in coating machines or equi-valent to finish and smooth the coating by blowing air onto it, e.g. to remove excess coating material, said air knife comprising a main channel into which the air is blown in the axial direction of the channel at least from one direction, the main channel being so constructed that there are two air jets flowing in opposite directions and having equal and constant velocities over the whole length. Thus the air jets discharged from slits next to a partition between the two main channel sections, after being merged, flow in a direc-tion perpendicular to the slit and the air flow is evenly distributed over the whole length of the slit. By using a construction in which the partition is movable, the location of the point at which the two jets mix can be varied, thus allowing the turbulence of the air jet blown at the web to be controlled and, consequently, an influence to be exerted on the properties of the coating surface.

The  pressure  transfer  medium  is  a gel-like material such as dimethyl  silicone and equivalents.   Alternatively,   the gel  may  be flourosilicone and the diaphragm may be dimethyl silicone.  The membrane material is chosen to be substantially  impermeable  to  the  ambients  or process media being measured and also flexible, is to be poured and cured in place on the assembly during fabrication.
