专利汇可以提供Apparatus for recording a temperature profile专利检索，专利查询，专利分析的服务。并且A highly accurate temperature-profiling package assembly includes a strip chart recorder and refrigerated ice water reference junction connected to a movable thermocouple junction which is reversibly motor driven through a disengageable screw and nut transmission, and position indicating buttons which control a switch for actuating a marking relay in the recorder which has a floating marking pen.，下面是Apparatus for recording a temperature profile专利的具体信息内容。
1. An apparatus for recording a temperature profile along a dimension within a heated enclosure such as a diffusion furnace, the apparatus comprising: a recorder assembly including a source of reference voltage; a temperature reference apparatus within the recorder assembly providing a stable reference temperature; a thermocouple junction; thermocouple wires of the same material as the thermocouple junction extending from the thermocouple junction to the temperature reference apparatus; a protective tubular member supporting the thermocouple wires from the thermocouple junction for a length at least as long as the dimension within the heated enclosure to be profiled; and means for moving the tubular member and thermocouple junction within the heated enclosure including a drive motor, a movable carriage assembly means for supporting the protective tubular member and including an electrical switch; a channel raiL for guiding said carriage assembly and having spaced switch actuators; and means for operatively connecting the drive motor and carriage assembly means and automatically stopping the carriage assembly means after profiling the temperature, whereby the electrical switch of the carriage assembly means is positioned to be actuated by the spaced switch actuators on the channel rail.
2. An apparatus as defined in claim 1 wherein the drive motor is a reversible motor and the means for operatively connecting the drive motor and carriage assembly means includes a lead screw having a nonthreaded relieved portion for automatically stopping the carriage assembly means.
3. An apparatus as defined in claim 2 wherein the channel rail supports the lead screw and motor.
4. An apparatus as defined in claim 3 wherein the channel rail is supported by brackets extending upwardly from the recorder assembly.
5. An apparatus as defined in claim 4 wherein the carriage assembly includes a split nut biased into engagement with the screw and mounted on a movable arm so as to be disengageable to allow the carriage to be moved along the channel rail manually.
6. An apparatus as defined in claim 2 wherein there are at least two separate drive motors and lead screw drive connections spaced apart on supporting brackets.
7. An apparatus as defined in claim 3 wherein the channel rail is slidably mounted on upstanding tubular member.
8. An apparatus as defined in claim 7 wherein the channel rail has means for securing said channel rail to said upstanding tubular members in a plurality of horizontal and vertical positions.
9. An apparatus as defined in claim 1 wherein the recorder assembly includes a marking pen and means floatingly mounting the pen on a pen carrier.
10. An apparatus as defined in claim 9 wherein the means floatingly mounting the pen comprises a pen arm with a pen on one end and a pivot connection adjacent the other end, means guiding the pen for limited pivotal movement adjacent pen end, and spring means biasing the pen toward a marking surface.
