Abstract: A sheathed and flanged temperature probe is formed using a cylindrical sheath and a flange of the same metallic material. The cylindrical sheath is closed on one end and open on the other, and has a length at least an order of magnitude greater than its outer diameter. The temperature sensing element is inserted into the sheath, leaving wires protruding from the open end of the sheath. The sheath may contain an epoxy in the closed end to insulate and stabilize the sensing element. The central portion of the sheath remains empty except for wires connecting the sensing element to the electrical leads. The open end of the sheath is sealed around two electrical leads, enclosing the temperature sensing element from ambient conditions. The flange member is formed from a single piece of metal, cold drawn using an awl to form a continuous sleeve having an axis perpendicular to the planar surface of the flange. The sheath is inserted into the sleeve.

Abstract: An apparatus and method for determining if a stone mounted in an electrically conductive mounting is a true diamond employs a housing to be held in one hand of a user while the other hand holds the mounting. An electrically and thermally conductive probe extends from the housing. The probe is held against the surface of the stone. Two assemblies connected to the probe measure sequentially to determine the thermal conductivity of the stone and the electrical conductivity of the stone. Displays indicate if the assemblies detect the high thermal conductivity of the stone consistent with diamond and the low electrical conductivity of the stone consistent with diamond. This apparatus distinguishes true diamond over such imitations as cubic zirconia with a lower thermal conductivity and moissanite with a higher electrical conductivity.

Abstract: This invention will provide a method of determining nondestructively, the purity or composition of an unknown material sample, such as, for example a sample of gold or silver of unknown purity. Their forms can be a: casting, bullion, coupon or disc (a coin), as well as some jewelry, such as gold or silver rings with signet surfaces. The test specimens are such that their areal dimensions are large compared to their thicknesses, thus qualifying as ‘slabs’. In order to detect a particular adulterant the method may require a dual-test procedure: The first is an application of a pulse of constant heat (or cold) and the second, if necessary, is an application of constant temperature. Furthermore, during the time the conditions are applied the slopes of the time-varying temperature patterns can be determined, the decay curves, after such conditions are removed, and their slopes can also be realized. Such information will provide a further check on the authenticity of the test item.

The delamination resistance at ambient temperature can be compared with a predetermined target value for delamination resistance in use.

Coated optical fiber having delamination resistances outside the predetermined ranges will typically be rejected.

Abstract: A temperature sensor for measuring a temperature of a substrate in a thermal processing chamber is described. The chamber includes a reflector forming a reflecting cavity with a substrate when the substrate is positioned in the chamber. The temperature sensor includes a probe having an input end positioned to receive radiation from the reflecting cavity, and a detector optically coupled to an output end of the probe. The radiation entering the probe includes reflected radiation and non-reflected radiation. The detector measures an intensity of a first portion of the radiation entering the probe to generate a first intensity signal and measures an intensity of a second portion of the radiation entering the probe to generate a second intensity signal. The detector is configured so that a ratio of the reflected radiation to the non-reflected radiation is higher in the first portion than the second portion. The two intensity signals are used to calculate the temperature and emissivity of the substrate.

Abstract: An IR transient thermography imaging system includes high-power flash lamps fitted with spectrally tuned optical filters and a focal-plane array camera for IR image data acquisition. The image data processing control computer analyzes acquired IR image data frames and provides a color-keyed display of an imaged object that correlates to object thickness over the imaged surface area. Acquisition of IR data is initiated at a firing of flash lamps used to heat a surface of the object along with a reference standard. A predetermined number of IR image frames are acquired and recorded over a predetermined period of time after firing of the lamps to develop a temperature-time (T-t) history of the object surface and the reference standard. A contrast curve is calculated for each pixel in the image frame, each pixel corresponding to an elemental region on the object surface.
