Abstract
Abstract A method for obtaining a connection between a feed pipe line and a branch pipe line, wherein an opening is made in the envelope surfaces of each line whereupon the branch pipe line, which has been provided with at least one annular sealing element is introduced through the openings of the feed pipe line until the opening in the branch pipe line is situated within the feed pipe line and until the sealing element for sealing the opening in the envelope surface of the feed pipe line under pressure contacts said envelope surface, so that the branch pipe line is permanently fixed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
A device for connecting a valve to a feed pipe line comprising: a. an inlet member extending transversely entirely through the feed pipe line, b. an inlet opening in said inlet member for receiving fluid from the feed pipe line, c. an external member attached to one end of said inlet member, said external member including a first abutment means, d. a first sealing means between said first abutment means and an exterior surface of the feed pipe line, e. said inlet member having an external portion at the other end thereof, said external portion having a second abutment means thereon, f. a second sealing means between said second abutment means and an exterior surface of the feed pipe line, g. a discharge passage and associated discharge opening in said inlet member, said discharge passage communicating with said inlet opening, h. a valve means in said inlet member between said inlet opening and said discharge passage, said valve means controlling flow from said inlet opening to said discharge opening, i. a shaft connected with said valve means, said shaft being disposed longitudinally within said discharge passage, j. said shaft having a portion extending from said discharge passage to the exterior of said inlet member, said extending portion having an operator member thereon, both said operator member and said discharge opening being disposed on the same side of said inlet member.
Claim 2
Independent Claim
230 words
A device for connecting a valve to a feed pipe line comprising: a. an inlet member extending transversely entirely through the feed pipe line, b. an inlet opening in said inlet member for receiving fluid from the feed pipe line, c. an external member attached to one end of said inlet member, said external member including a first abutment means, d. a first sealing means between said first abutment means and an exterior surface of the feed pipe line, e. said inlet member having an external portion at the other end thereof, said external portion having a second abutment means thereon, f. a second sealing means between said second abutment means and an exterior surface of the feed pipe line, g. a discharge passage and associated discharge opening in said inlet member, said discharge passage communicating with said inlet opening, h. a valve means in said inlet member between said inlet opening and said discharge passage, said valve means controlling flow from said inlet opening to said discharge opening, i. a shaft connected with said valve means, said shaft being disposed longitudinally within said discharge passage, j. said shaft having a portion extending from said discharge passage to the exterior of said inlet member, said extending portion having an operator member thereon, both said operator member and said discharge opening being disposed on the same side of said inlet member.
Claim 3
Dependent Claim
33 words
A device as defined in claim 1, wherein said inlet opening comprises a pair of spaced, co-axial ports, the axis of said ports being parallel to the axis of the feed pipe line.
Claim 4
Dependent Claim
31 words
A device as defined in claim 1, wherein said valve means includes a conical valve seat and corresponding conical valve member, said valve member being axially displaceable in said inlet member.
Claim 5
Dependent Claim
135 words
A pipe line valve connection comprising: a. a feed pipe line having a lateral opening therein, b. a nut fixedly mounted on an exterior surface of said feed pipe line in concentric relationship with said laterAl opening, c. an inlet member disposed in said lateral opening and threadably engaging said nut, said inlet member having a first portion extending to the exterior of said feed pipe line, and a second portion extending into the interior of said feed pipe line, d. an abutment means on said first portion of said inlet member, e. a sealing means between said abutment means and said nut, f. an inlet opening in said second portion of said inlet member, g. a valve means in said inlet member for controlling flow from said feed pipe line through said inlet member.
Claim 6
Dependent Claim
135 words
A pipe line valve connection comprising: a. a feed pipe line having a lateral opening therein, b. a nut fixedly mounted on an exterior surface of said feed pipe line in concentric relationship with said laterAl opening, c. an inlet member disposed in said lateral opening and threadably engaging said nut, said inlet member having a first portion extending to the exterior of said feed pipe line, and a second portion extending into the interior of said feed pipe line, d. an abutment means on said first portion of said inlet member, e. a sealing means between said abutment means and said nut, f. an inlet opening in said second portion of said inlet member, g. a valve means in said inlet member for controlling flow from said feed pipe line through said inlet member.
Claim 7
Dependent Claim
57 words
A pipe line valve connection as defined in claim 4, a. wherein said valve means includes a moveable member, b. said moveable member having a valve operator associated therewith, c. said valve means having a discharge opening associated therewith, d. said moveable member and said discharge opening being on the same side of said feed pipe line.
Claim 8
Dependent Claim
73 words
A pipe line valve connection as defined in claim 5, a. wherein said moveable member has an inlet flow groove therein b. said moveable member having a guide flange cooperating with said inlet member, c. a flow channel in said guide flange, said flow channel communicating with said discharge opening, d. said inlet flow groove and said flow channel effecting communication between the interior of said feed pipe line and said discharge opening.
Claim 9
Dependent Claim
60 words
A pipe line valve connection as defined in claim 5 a. wherein said inlet member includes an inlet opening, b. said moveable member having a sealing element therein, c. said sealing element being engagable with said inlet member in an area surrounding said inlet opening to control flow between the interior of said feed pipe line and said discharge opening.
