Abstract: A method for the inspection of a condition, in particular for the detection of defects, of a cannula (or injection needle) mounted on a syringe, which is located under a protective cap, and devices for carrying out such methods. A method includes measuring a magnetic field, in particular a magnetic field distribution, in the vicinity of the cannula. The presence of a ferromagnetic cannula causes a local change in the course of the magnetic field lines. This can be measured and used to determine whether the cannula, as desired, is arranged straight and coaxially to the syringe longitudinal axis, or whether it has a defect, such as being bent, kinked, compressed, broken/severed, oblique to the longitudinal axis of the syringe or eccentric to the longitudinal axis of the syringe.

Abstract: A method for measuring a concentration of a gas in a container having a wall with at least one deformable portion, the gas absorbing electromagnetic radiation at least in a specific spectral range, wherein the method includes the steps of biasing deformable portion and a further portion of wall opposite deformable portion between opposite positioning surfaces, thereby forming a biased volume of the container between the opposite positioning surfaces, during a measuring time, transmitting electromagnetic radiation into biased volume and receiving transmitted or reflected radiation of transmitted radiation from biased volume along respective radiation paths, relatively moving, during measuring time, at least one of deformable portion and of further portion and at least one of radiation paths, and determining concentration of said gas from the radiation received.

Abstract: A method of measuring a concentration of a gas in the headspace of a container is provided. The headspace contains particles and/or droplets and/or the container carries on an exterior section surrounding the headspace particles and/or droplets. The container is at least in parts transparent to electromagnetic radiation. The method comprises the steps: subjecting said headspace to input electromagnetic radiation; receiving from said headspace output electromagnetic radiation in form of transmitted and/or reflected and/or diffused input electromagnetic radiation; and generating from said received electromagnetic radiation a concentration indicative result; thereby diffusing outside the container and distant from the container said input electromagnetic radiation and/or diffusing outside the container and distant from the container said output electromagnetic radiation and/or moving said headspace with respect to said input electromagnetic radiation.

Abstract: A coarse-fine two-stage leak detection is carried out on sealed, filled containers loaded into container holders or “pucks”. Failure of the first, coarse leak detection stage, e.g. a pressure-course or impedance or laser-absorption based leak detection stage, causes containers to be rejected together with their corresponding container holders. These are then separated, and the container holder is cleaned and dried before being returned to the system. Any leaking product from inside a grossly leaking container is thus retained within the container holder, thus reducing contamination of subsequent containers and their container holders, preventing such contamination from reaching the fine leak detection stage, e.g. a mass-spectrometer-based leak detection stage.

Abstract: A method and a system for detecting the presence of propellant gas in a gaseous sample exploit laser light especially in the 3.30-3.5 ?m range. The propellant can be propane, n-butane, i-butane, dimethyl ether, methyl ethyl ether, HFA 134a, HFA 227, or any other propellant exhibiting absorption in the requisite wavelength range. The presence of the application of this method in leak testing of propellant-containing containers such as aerosols or fuel canisters, permits high-speed, high accuracy leak detection capable of replacing existing testing methods.

Within the timespan the monitoring unit is applied to the device, the monitoring unit is operated in a standalone operating mode. During a timespan information about the device to which the monitoring unit is applied is collected in the monitoring unit. This timespan of collecting includes at least a part of the timespan during which the monitoring unit is operated in standalone mode.

Abstract: Method and system for x-ray detection of flaws in containers or their contents wherein containers are conveyed on a circular path around a central axis upon which an x-ray source is situated below the plane of the base of the containers. The x-ray source emits x-ray radiation obliquely upwards through the containers to a plurality of imaging x-ray detectors. Analysis of the images provided by these x-ray detectors determines the presence of a flaw in a container or its contents and is used to command a rejection mechanism to reject the container in question.

Abstract: Disclosed are methods and an apparatuses for loading and unloading objects into/from corresponding cavities in holders at a high count rate. For loading, a plurality of objects are present on an object path which mutually converges with a holder path. For unloading, the object path mutually diverges from the holder path. Integration of this method and apparatus respectively into a method of manufacturing unleaky containers and a corresponding apparatus for leak testing containers is also proposed.

Abstract: For leak testing closed containers (9) which are filled with a filling product containing at least one liquid component the container is introduced in a test cavity (1) which is evacuated at least down to vapor pressure of that liquid component. The pressure in the surrounding of the container (9) and thus within test cavity (1) is monitored. Monitoring is performed by a vacuum pressure sensor (7), whereas lowering pressure surrounding the container (9) is performed by a vacuum pump (5). Leakage is detected by monitoring a pressure change in the surrounding of the container which is due to evaporation of liquid emerging from a leak and being evaporated in the low pressure surrounding.
