Abstract
Abstract An apparatus for distributing a liquid-vapor mixture into two or more separate streams or paths involving a hollow vessel having a fluid inlet means; at least two pipe means each of which have one end extending into the vessel, each pipe means being in fluid communication with a different path for liquid-vapor flow from the hollow vessel; at least one aperture in that part of each of the pipe means extending into the vessel and restrictive means located in the vessel to restrict fluid flow directly into the top openings of the pipe means. An improved method for distributing a liquid-vapor mixture is also disclosed.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
188 words
A distribution apparatus for distributing a mass of fluid comprising a liquid-vapor mixture into at least two separate streams which comprises: 1. a hollow vessel having at least one fluid inlet means; 2. at least two hollow distributor pipe means each having a top opening located at a first end of said pipe means which extends into said vessel, each of said pipe means providing outlet means from said vessel for a different portion of said fluid, provided that said fluid inlet means is located at a level above said top openings of said pipe means; 3. at least one aperture located in that part of each said pipe means extending to said vessel below said first end of said pipe means to provide fluid communication between the interior of said vessel and the hollow space of said pipe means; and 4. restrictive means located within said hollow vessel at a level above the top openings of said pipe means to restrict the flow of fluid from said fluid inlet means directly into the hollow space of said pipe means through the top openings of said pipe means.
Claim 2
Dependent Claim
188 words
A distribution apparatus for distributing a mass of fluid comprising a liquid-vapor mixture into at least two separate streams which comprises: 1. a hollow vessel having at least one fluid inlet means; 2. at least two hollow distributor pipe means each having a top opening located at a first end of said pipe means which extends into said vessel, each of said pipe means providing outlet means from said vessel for a different portion of said fluid, provided that said fluid inlet means is located at a level above said top openings of said pipe means; 3. at least one aperture located in that part of each said pipe means extending to said vessel below said first end of said pipe means to provide fluid communication between the interior of said vessel and the hollow space of said pipe means; and 4. restrictive means located within said hollow vessel at a level above the top openings of said pipe means to restrict the flow of fluid from said fluid inlet means directly into the hollow space of said pipe means through the top openings of said pipe means.
Claim 3
Dependent Claim
63 words
at least two hollow distributor pipe means each having a top opening located at a first end of said pipe means which extends into said vessel, each of said pipe means providing outlet means from said vessel for a different portion of said fluid, provided that said fluid inlet means is located at a level above said top openings of said pipe means;
Claim 4
Dependent Claim
63 words
at least two hollow distributor pipe means each having a top opening located at a first end of said pipe means which extends into said vessel, each of said pipe means providing outlet means from said vessel for a different portion of said fluid, provided that said fluid inlet means is located at a level above said top openings of said pipe means;
Claim 5
Dependent Claim
19 words

Claim 7
Dependent Claim
44 words
at least one aperture located in that part of each said pipe means extending to said vessel below said first end of said pipe means to provide fluid communication between the interior of said vessel and the hollow space of said pipe means; and
Claim 8
Dependent Claim
44 words
at least one aperture located in that part of each said pipe means extending to said vessel below said first end of said pipe means to provide fluid communication between the interior of said vessel and the hollow space of said pipe means; and
Claim 9
Dependent Claim
46 words
restrictive means located within said hollow vessel at a level above the top openings of said pipe means to restrict the flow of fluid from said fluid inlet means directly into the hollow space of said pipe means through the top openings of said pipe means.
Claim 10
Dependent Claim
46 words
restrictive means located within said hollow vessel at a level above the top openings of said pipe means to restrict the flow of fluid from said fluid inlet means directly into the hollow space of said pipe means through the top openings of said pipe means.
Claim 11
Dependent Claim
39 words
