Abstract: A triple point cell comprising: 1) An outer vessel and an inner vessel; 2) an elastomeric stopper that fits inside the open end of the outer vessel; the elastomeric stopper has two holes, one through which the inner vessel is tightly fitted, and a second through which unwanted gasses is allowed to escape; 3) water in the volume between the outer and inner vessels. 4) a vent plug for plugging up the second hole after all the unwanted gases has been driven out of the triple point cell by water vapor that has been generated by boiling the water. Triple point is reached by freezing some of the water in the cell, and then letting the ice, water, and water vapor come to thermal equilibrium.

Abstract: A finger-controlled device for pushing slide bars, including two sets of data carriers, two slide bars and a finger-controlled section for moving the slide bars. Each data carrier corresponds to a sensor for reading 0, 1 signals. Each data carrier has a central shaft disposed with a gear. A face of each slide bar is formed with a rack facing the central shaft for meshing with the gears. The finger-controlled section is movable relative to a housing having an interior chambers for receiving the data carriers, sensors and slide bars. Four side walls of the chamber are formed with through holes for the slide bars to pass therethrough. The housing restrains the slide bars to move relative to and across each other. In operation, the slide bars are moved relative to each other as the finger-controlled section is moved, whereby the data carriers are rotated by a fixed number of circles for use in absolute coordinate input alignment. The slide bars can be widened and thickened to have greater bending strength.

Abstract: A gauge is provided that is useful in measuring the horizontal wheelbase of a railway freight car truck sideframe. The gauge itself is comprised of a main horizontal body section usually of a single piece of aluminum bar stock. A stationary depending leg extends downwardly and is affixed to near one end of the main horizontal body section. A bearing slide assembly is affixed to the main horizontal body section near its other end. A measuring leg depends from the bearing slide assembly and is movable along the bearing slide assembly. An indicator scale is associated with the measuring leg so that its relative position with regard to the main horizontal body can be readily measured from a scale affixed thereon. The stationary depending leg is brought into contact with one edge of a pedestal jaw of the railway freight car sideframe, and the measuring leg is moved into contact along the bearing slide assembly with an opposite edge of the opposite pedestal jaw.

Abstract: The accuracy of the axial degree of a lens in an eyeglass production is improved. In an eyeglass frame measuring apparatus, first and second frame data on the eyeglass frame consisting of first and second frames are entered. The entered first frame data are inverted to obtain a third frame data. On the basis of the third frame data and the entered second frame data, an amount of deviation of the second frame data with respect to the third frame data in a rotation direction is obtained. An eyeglass lens is processed on the basis of the rotation deviation amount and the third frame data.

Abstract: Apparatus for and methods of meauring heat flux comprises first and second sensors arranged to pass through an oven in line astern. Each sensor measures the temperature difference across a thermally insulating layer by having one surface of each sensor being exposed to the heat flux, each sensor including thermocouple measuring junctions for measuring the temperature of the exposed surface. The first sensor is radiation-absorbing and the second sensor is reflecting. The apparatus includes additional thermocouple junctions for measuring the gas temperature and a device for recording data from the sensors and from additional thermocouple junctions. The signals from one of the sensors at one instant are correlated with the corresponding signals from the other sensor at a later instant, the time difference being the time taken for one sensor to reach a position formerly occupied by the other sensor.

Abstract: A probe tip in combination with a seal assembly that prevents debris and other contaminants from entering the probe tip. In the preferred embodiment, the seal comprises a tube with a filter holder assembly attached at the distal end of the holder. The filter holder assembly includes an infrared filter seated inside a screw-on member that is attached to a holder member with a sealing member located directly behind the infrared filter. During manufacturing, a predetermined force is applied to the proximal end of the tube which drives the distal end of the tube and filter holder assembly against the probe tip opening, thereby forming a watertight seal thereto. In alternative embodiments, the seal assembly may be comprised of a collar and gasket combination instead of a filter holder assembly.

Abstract: A scribe/guide tool used as a compass and to layout stair stringers.

Abstract: A technique and system for tuning temperature sensor readings in a thermal processing chamber includes determining an actual temperature profile for a substrate based on measurements of the substrate. A simulated temperature profile for the substrate is calculated using a respective interim temperature correction value for one or more temperature sensors associated with the chamber. A Gaussian-like distribution for thermal contributions from multiple radiation sources in the chamber can be used to simulate the temperature profile. The simulated temperature profile and the actual temperature profile are combined to form an estimated temperature profile. A final value for each respective temperature correction value is determined using an optimization algorithm which results in the estimated temperature profile being substantially uniform across the surface of the substrate.

Abstract: A fiber optic hygrometer apparatus and method for sensing and measuring the dew point of an atmosphere is disclosed that includes a controller for controlling the operation of the apparatus and a first optical fiber for transmitting light energy from a source of light energy to an optical core extending into the atmosphere being monitored. The optical core includes an end that is prepared as a reflecting surface, allowing the light energy reaching the optical core to be internally reflected back toward the source. A second optical fiber captures the light energy internally reflected from the optical core and conveys the captured light energy to a light energy detector. The light energy detector is arranged to output signals to the controller representing the magnitude of the light energy captured. A cooling device and a temperature-sensing device operationally connected to the controller are attached to the optical core.

Abstract: In a tympanic thermometer probe cover including a film, an additional, substantially non-stretchable structure is mechanically coupled to the film in the area where the probe contacts the film. This additional structure is designed so that it does not occlude infrared radiation from reaching the probe while maintaining the portion of the film over the probe distal end in a prestretched, wrinkle-free condition and preventing that portion of the film from stretching further. The structure may comprise a concentric registration ring that is adhered to the film. The registration ring includes a central open hole portion through which infrared radiation may pass without occlusion. The ring self-adheres to the film, maintaining the film in a prestretched, wrinkle-free condition. When the probe cover is applied to the probe, the probe contacts the ring. Since the ring is substantially non-stretchable, the ring prevents the film from further stretching over the probe.
