Abstract
Abstract An automatic temperature measuring device for measuring the temperature of a medium which flows out from a plurality of separate inner chambers through the end thereof, which inner chambers extend in a container axially parallel to its longitudinal axis. A temperature feeler is movable outside the container in a plane perpendicular to the container axis and can be positioned in front of each end opening of each inner chamber. The temperature feeler is arranged on a link chain which can be bent in only one direction from the extended position, the members of which link chain due to gravity support one another to form a straight arm positioned in the mentioned plane of movement. A guide extends laterally of the container and axially parallel to same and is bent to point into the plane of movement. The guide is rotatable about its axis and the chain can be driven in and out of the guide whereby the temperature feeler is movable in the plane in any circular arc or radius.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
182 words
Automatic device for measuring the temperature of a medium which flows out from a plurality of separate inner chambers in a container through the end of each inner chamber, which inner chambers extend axially parallel to the longitudinal axis of said container, characterized in that a temperature feeler is movable in a plane perpendicular to the container axis and is positionable in front of each end opening of each inner chamber, the temperature feeler being arranged on a link end member of a link chain which can be bent only in one direction from an extended position, the members of said link chain due to gravity supporting one another to form a straight arm positioned in said plane or movement, and a guide for the link chain extending laterally of the container and axially parallel to same and having an end section bent through substantially a quarter of a circle and pointing into said plane of movement, the guide being rotatable about its axis which is parallel to the container and from which guide the chain can be driven in and out.
Claim 2
Dependent Claim
182 words
Automatic device for measuring the temperature of a medium which flows out from a plurality of separate inner chambers in a container through the end of each inner chamber, which inner chambers extend axially parallel to the longitudinal axis of said container, characterized in that a temperature feeler is movable in a plane perpendicular to the container axis and is positionable in front of each end opening of each inner chamber, the temperature feeler being arranged on a link end member of a link chain which can be bent only in one direction from an extended position, the members of said link chain due to gravity supporting one another to form a straight arm positioned in said plane or movement, and a guide for the link chain extending laterally of the container and axially parallel to same and having an end section bent through substantially a quarter of a circle and pointing into said plane of movement, the guide being rotatable about its axis which is parallel to the container and from which guide the chain can be driven in and out.
Claim 3
Dependent Claim
49 words
Temperature measuring device according to claim 1, characterized in that drive means is associated with both the chain and the guide for moving the chain in and out of the guide and for rotating the guide about its axis to thereby swing the chain end member within said plane.
Claim 4
Dependent Claim
123 words
Temperature measuring device according to claim 2, characterized in that the guided end of the chain is connected to a reciprocating hollow rod, said drive means being disposed externally of the container and connected to the hollow rod for reciprocating same, said drive means including a screw mechanism coacting with the rod for reciprocating same, the screw mechanism including a ball spindle portion provided on the outside of the rod and a counter-threaded sleeve member surrounding the rod and rotated by motor means for causing reciprocating movement of said rod whereby said chain is driven in and out of said guide, and said thermal-couple as provided at the link end member being connected to an inlet lead which extends through said hollow rod.
Claim 5
Dependent Claim
73 words
Temperature measuring device according to claim 3, characterized in that the drive means also includes a hollow tube member disposed in surrounding relationship to said reciprocating rod, said hollow tube member having one end thereof connected to said guide, said hollow tube member extending externally of said container and gear means drivingly connected to the external end of said tube member for causing rotation thereof whereby said guide is rotated about its axis.
Claim 6
Dependent Claim
47 words
Temperature measuring device according to claim 2, wherein said drive means is disposed externally of said container and includes rotatable means connected to said guide for rotating same, said drive means including reciprocating means connected to said chain for reciprocating same in and out of said guide.
Claim 7
Dependent Claim
16 words
Temperature measuring device according to claim 1 characterized in that the temperature feeler is a thermo-couple.
Claim 8
Dependent Claim
31 words
Temperature measuring device according to claim 6, characterized in that the inlet lead for the thermo-couple extends through the link members and is arranged along the longitudinal axis of said chain.
Claim 9
Dependent Claim
39 words
Temperature measuring device according to claim 1, characterized in that the guide for the chain is a tube with a square cross section which has in the quarter circular bent section two oppositely inclined and two plane inner surfaces.
Claim 10
Dependent Claim
45 words
Temperature measuring device according to claim 4, characterized in that each link member of the link chain carries two guide rollers positioned on the diagonally opposite ends of each link member with said guide rollers engaging the two inclined inner surfaces of the guide tube.
Claim 11
Dependent Claim
40 words
Temperature measuring device according to claim 1, characterized in That the link chain has a length at least equal to the diameter of the container plus the addition of the length of the quarter circular bent section of the guide.
