A microstrip-type microwave sensor for the measurement of the dielectric properties of a solid or liquid material, constituted by a main line and two connected transmission lines integral at one of their extremities to the main line, the main line and two connected transmission lines being spaced from one another by a slot and being made integral with a substrate. The main line is connected to an electrical circuit by each of its two extremities to inject a sinusoidal signal, and wherein said main line has a width giving it an impedance in the range 50 Ohm, the two connected transmission lines being of the same width and of a length equal to one quarter of the wavelength guided in the substrate, the substrate having a height or thickness giving it flexibility or rigidity, the substrate being applied to a metallic support formed of a layer of metallic material.

A method for testing the strength of a sheet-like element having two opposite faces and made of hard brittle material under tensile stress is provided. The method includes passing each of the faces of the element over a roller and thereby bending the element so that each of the faces is subjected to a first tensile stress in a portion in which the opposite face is in contact with a surface of the roller; exerting a second tensile force on the element in the direction of advancement so that both faces are subjected to the second tensile stress of at least 2 MPa so that the first and second tensile stresses add up to define a resultant tensile stress; and monitoring the element and determining whether the element has a defined breaking strength equal to the resultant tensile stress or whether the element breaks under the resultant tensile stress.

A system and method for producing period-coded glass containers is disclosed. One method comprises producing a glass container from a traceable material composition associated with a predetermined time period, manufacturing facility, and/or time of container manufacture, where the glass container is configured to be analyzed for the traceable material composition, and at least one of constituents of or amounts of materials in the traceable material composition is configured to be identified and cross-referenced to a cross-reference schedule for identifying the time period, manufacturing facility, and/or time of container manufacture in which the glass container was produced.

A method of controlling compaction including obtaining a plurality of sets of process conditions for a plurality of glass ribbons, measuring a compaction value for a glass sheet cut from each glass ribbon of the plurality of glass ribbons, correlating the compaction to the process conditions. The method further includes selecting a predetermined cooling curve including a plurality of cooling rates, modifying the cooling curve by varying cooling rates of the plurality of cooling rates, calculating a predicted compaction value for a glass sheet cut from a glass ribbon drawn using the modified cooling curve, and repeating the modification and predicting until compaction is minimized.

A method for detecting metal particles (21) present in a wall (20) of a glass container (2) intended to contain food or pharmaceutical products, said method comprising the steps of: —heating the metal particles (21) present in the wall (20); —inspecting the container (2) during or after said step of heating the metal particles (21) present in the wall (20). The step of heating the metal particles (21) envisages increasing the temperature of the metal particles (21) to a greater extent than the remaining glass parts (22) of the wall (20). The method comprises the step of inspecting the container (2) using means (71) for detecting the metal particles (21) which are hotter than the glass parts (22) of the wall (20).

A glass element has, per kg of glass, 50 or fewer inclusions having a size of 2 μm to 10 μm. The glass element can be made of borosilicate glass.

A glass article is designed at least in part in the form of a glass tube element including at least one shell which encloses at least one lumen. For at least one light transmission analysis of the glass article, a ratio of an average amplitude transmission factor and a specific amplitude transmission factor is greater than 1.00001.

The systems and methods include generating polarization-switched (PS) detector and reference signals using a polarization switch controlled by a digital control signal generated by digital input/output card. A gain adjustment is performed on the PS detector and reference signals to define gain-adjusted detector and reference signals. The digital control signal is used to synchronize the gain-adjusted PS detector and reference signals to define gain-adjusted synchronized PS detector and reference signals each having respective steady-state portions. The steady state portions are used to define a measurement signal. The measurement signal is then used to calculate a stress-based characteristic of the sample being measured. The sample can be moved continuously or discretely through different measurement positions, which are synchronized with the operation of the polarization switch using the digital control signal.
