A single crystal manufacturing apparatus 10 according to the present invention is provided with a single crystal puller pulling up a single crystal 15 from a melt 13, a camera 18 photographing a fusion ring generated at the boundary between the melt 13 and the single crystal 15 and an computer 24 processing a photographed image taken by the camera 18. The computer 24 projects and converts the fusion ring appearing in the photographed image taken by the camera 18 on a reference plane corresponding to the liquid level position of the melt based on an installation angle and a focal length of the camera and calculates a diameter of the single crystal 15 from a shape of the fusion ring on the reference plane.

The present disclosure relates to a method for calibrating a stationary THz measuring device which measures geometric properties of a profile by means of one or more THz sensors during an extrusion of the profile, comprising at least one or more steps.

A distance sensor is used for automatically determining the size of a wheel on a mobile machine. The distance sensor is mounted to detect distance information relating to a distance between the sensor and an outer circumferential surface of the wheel. The distance information is received by a controller configured to determine the radius of the wheel based at least in part on the distance information. The controller may compare the measured radius with data for a range of standard wheel sizes and determine which standard wheel size is fitted. The measured wheel radius and/or the determined standard wheel size can used as an input for a control system on the machine which requires wheel size data, such as an axle height adjustment system.

The invention concerns a method for measuring the dimensions of empty glass containers (2) consisting in: selecting at least one region to be inspected of the container, transporting the containers, positioning, on either side of the region to be inspected, at least one focus of an X-ray generator tube and image sensors, acquiring, using image sensors, for each container during its displacement, at least three radiographic images of the inspected region, analyzing the at least three radiographic images so as to determine the three-dimensional coordinates of a set of points to deduce at least one inner diameter of the neck and/or one thickness of the body.

A control system is provided for a converting line. The converting line has an unwinder for unwinding web material from a roll of web material and at least one independently driven roll for directing the web material unwound from the unwinder to the converting line. The control system has a controller and a tension sensor configured to be arranged downstream of the at least one driven roll. The tension sensor is configured to sense a tension in the web as the web is passed downstream of the driven roll, generate a signal indicative of sensed web tension, and transmit the signal of sensed web tension to the controller. The controller is configured to a generate and transmit to the unwinder a signal to change the speed of the unwinder based upon the tension sensed by the tension sensor.

An automated log scaling system and associated methods are disclosed. In the system and methods, one or more imagers may capture depictions of respective first ends and/or second ends of a plurality of logs, and use the captured depictions to scale the plurality of logs. A diameter value for each end of the log may be determined using the captured depictions. Relative location values for each captured end may be determined and used to form a length of each log. Information captured in the images is used to identify the type of tree or species of tree for each log. At least one of the diameter values may be multiplied by the determined log length, and the resulting product value may be compared to values in a log scaling chart to determine a value for the log. The value of multiple logs may be used to form a load of logs for distribution.

A method of obtaining a numerical model is disclosed. The numerical model correlates estimated capillary tube output diameter values to minimum pressure for gas bubble generation (MPGBG) values. An MPGBG value of each capillary tube in the reference group is measured for a liquid. An output diameter of each of the capillary tubes is measured by a microscope apparatus. A numerical model that correlates estimated capillary tube output diameter values to MPGBG values for the liquid is calculated. A method of estimating an output diameter of a capillary tube includes the following steps. An MPGBG value of the capillary tube for a liquid is measured, and the measured MPGBG value is input into the numerical model to estimate the capillary tube output diameter value. Other methods include a method of estimating an output diameter value of a capillary tube in a test group, a method of estimating and storing output diameter values of capillary tubes in a test group, methods of selecting at least one capillary tube from a plurality of capillary tubes in a test group, and a method of cutting a capillary tube to a desired estimated capillary tube output diameter value.
