Abstract

Abstract An infrared temperature probe for high pressure use is in the form of a hollow bolt adapted to be threaded into a complementary threaded aperture in the wall of a pressure vessel with the end thereof disposed flush with the internal surface of the pressure vessel wall. An infrared transparent window is secured in the end of the hollow bolt with one surface thereof disposed flush with the end of the bolt. A bundle of optical fibers is secured within the opposite end of the hollow bolt and a glass rod is mounted within the hollow bolt in operative relation to the window and the optical fiber bundle for transmitting infrared radiation from the window to the optical fiber bundle. The interior of the hollow bolt may be supplied wth a circulating cooling liquid or gas. An infrared temperature probe can also be used with a mold having an aperture for receiving an ejector pin wherein the hollow ejector pin is provided with an impact surface at one end and an infrared transparent window in the opposite end for receiving infrared radiation from a hot moulded article within the mold when the ejector pin is located within the aperture in the mold. A bundle of optical fibers extends through the hollow ejector pin and is disposed in optical transmitting engagement with the window.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 112 words
An infrared temperature probe for high pressure use comprising a hollow bolt adapted to be threaded into a complimentary threaded aperture in the wall of a pressure vessel with the end thereof disposed flush with the internal surface of the pressure vessel wall, an infrared transparent window secured in the end of said hollow bolt with one surface thereof disposed adjacent said end of said bolt, a bundle of optical fibers secured within the opposite end of said hollow bolt and a glass rod mounted within said hollow bolt in operative relation to said window and said optical fiber bundle for transmitting infrared radiation from said window to said optical fiber bundle.
Claim 2
Dependent Claim 112 words
An infrared temperature probe for high pressure use comprising a hollow bolt adapted to be threaded into a complimentary threaded aperture in the wall of a pressure vessel with the end thereof disposed flush with the internal surface of the pressure vessel wall, an infrared transparent window secured in the end of said hollow bolt with one surface thereof disposed adjacent said end of said bolt, a bundle of optical fibers secured within the opposite end of said hollow bolt and a glass rod mounted within said hollow bolt in operative relation to said window and said optical fiber bundle for transmitting infrared radiation from said window to said optical fiber bundle.
Claim 3
Dependent Claim 53 words
An infrared temperature probe as set forth in Claim 1, wherein means are provided for supporting opposite ends of said glass rod in close proximity to said window and said optical fiber bundle with the principal portion of the length of said glass rod being disposed in spaced concentric relation to said bolt.
Claim 4
Dependent Claim 44 words
An infrared temperature probe as set forth in Claim 1, wherein said window is comprised of a truncated sapphire cone supported over substantially its entire length by said bolt with the larger diameter face thereof being disposed flush with said end of said bolt.
Claim 5
Dependent Claim 61 words
An infrared temperature probe as set forth in Claim 1, wherein said window is comprised of a truncated sapphire cone supported over substantially its entire length by said bolt and further comprising retaining means secured to the end of said bolt in engagement with the larger diameter end face of said cone to assist in securing said cone to said bolt.
Claim 6
Dependent Claim 30 words
An infrared temperature probe as set forth in Claim 1, wherein said glass rod is comprised of a central core of one material and a glass cladding of another material.
Claim 7
Dependent Claim 36 words
An infrared temperature probe as set forth in Claim 1, further comprising means for circulating cooling air along substantially the entire length of said glass rod in the space between said glass rod and said bolt.
Claim 8
Dependent Claim 127 words
An infrared temperature probe for high pressure use comprising an elongated hollow sleeve adapted to be threadably connected in a threaded bore extending through the wall of the pressure vessel with the end of said sleeve being disposed flush with the inner surface of the pressure vessel wall, a glass rod having a stainless steel cladding extending along the entire length thereof with the ends of the glass rod being uncovered, a sleeve secured to said stainless steel clad glass rod along a portion of the length thereof for supporting said rod within said hollow tubular sleeve, complimentary threaded means on said sleeves whereby upon rotation of said sleeve secured to said rod, said rod can be advanced or retracted into or out of said pressure vessel.
Claim 9
Dependent Claim 127 words
An infrared temperature probe for high pressure use comprising an elongated hollow sleeve adapted to be threadably connected in a threaded bore extending through the wall of the pressure vessel with the end of said sleeve being disposed flush with the inner surface of the pressure vessel wall, a glass rod having a stainless steel cladding extending along the entire length thereof with the ends of the glass rod being uncovered, a sleeve secured to said stainless steel clad glass rod along a portion of the length thereof for supporting said rod within said hollow tubular sleeve, complimentary threaded means on said sleeves whereby upon rotation of said sleeve secured to said rod, said rod can be advanced or retracted into or out of said pressure vessel.
Claim 10
Dependent Claim 30 words
An infrared temperature probe as set forth in Claim 7, further comprising sealing means between said hollow sleeve and said rod to prevent leakage of material from said pressure vessel.
Claim 11
Dependent Claim 117 words
An infrared temperature probe for use with a mold having an aperture therein for receiving an ejector pin, a hollow ejector pin having an impact surface at one end and an infrared transparent window secuted in the opposite end thereof for receiving the infrared radiation from a hot molded article within the mold when said ejector pin is located within said aperture in said mold, a bundle of optical fibers extending through said hollow ejector pin and disposed in optical transmitting enegagement with said window and recess means in the end of said ejector pin adjacent said impact surface to provide a passage for said bundle of optical fibers laterally of the axis of said ejector pin.
Claim 12
Dependent Claim 117 words
