A method for manufacturing a battery is provided and including preparing the battery comprising an exterior material, the exterior material comprising a sealed portion; housing at least the sealed portion of the battery in a space portion of a chamber; providing the space portion into a pressurized state; and opening a partial portion of the battery other than the sealed portion to an atmosphere.

An apparatus and method is provided for the detection of a leak between a container and a flexible cover secured about an opening in the container. The apparatus comprises a vacuum chamber for receiving the container, a pressure indicating sensor coupled to a controller; and a sensor support. The sensor is positioned on the sensor support wherein, in operation, the sensor is located in close proximity to the container cover such that when the container is within the vacuum chamber and subjected to a vacuum condition, gases within the container cause the cover to expand at the location of a leak between the cover and the container. Upon contact with the cover the sensor generates a signal received by the controller to indicate both the detection and the location of the leak about the opening in the container.

The present invention relates to a testing station for testing for the tightness of one or more vacuum packages, where each of the one or more vacuum packages has an initial spatial dimension at a reference pressure, comprising a negative pressure generating device which is configured to act upon the one or more vacuum packages from the outside with the test pressure which is reduced in comparison to the reference pressure, and a sensor system which is configured to determine, based on a change in the spatial dimension of at least one of the one or more vacuum packages during the application of the test pressure relative to the respective initial spatial dimension of the one or more vacuum packages, whether at least one of the one or more vacuum packages is leaking.

The invention relates to a method for leakage detection on at least one flexible test piece in a film chamber, including inserting the at least one test piece into a film chamber, lowering the pressure in the film chamber outside the at least one test piece, and detecting a leakage in the at least one test piece by observing the spatial change of the film of the film chamber. The outer contour of the at least one test piece is transferred to at least one section of the film by the lowering of the pressure in the film chamber. The contour of the film is recorded with an image recording system, and the recorded images of the contour are compared with reference images of said contour in the event of a tight test piece.

A system for detecting leaks in a sealed insulating glass unit (IGU) includes a pressure source, a flow path that extends between the pressure source and a distal end removably coupleable to the IGU to place the pressure source in fluid communication with an interior space of the IGU, and a pressure sensor to monitor a pressure level in the interior space. A method for testing the IGU for leaks includes applying a pressure to an interior space of the sealed IGU, monitoring the pressure in the interior space, and determining whether one or more failure conditions exists by comparing the monitored pressure to a desired pressure after a specified period of time. The IGU failure exists if the monitored pressure is less than the desired pressure (e.g., less than the desired pressure by more than a predetermined amount) after a first specified period of time, if after reaching the desired pressure the difference between the applied pressure and the desired pressure is greater than a predetermined amount after a second specified period of time, or if one or more of the glass lites breaks.

A method for manufacturing a battery is provided and including preparing the battery comprising an exterior material, the exterior material comprising a sealed portion; housing at least the sealed portion of the battery in a space portion of a chamber; providing the space portion into a pressurized state; and opening a partial portion of the battery other than the sealed portion to an atmosphere.

The invention relates to methods for inspecting objects fed in a continuous flow, in particular packages or components, wherein an inspecting body is guided along an inspection segment together with an object and a response to an inspection of the object is detected by means of a sensor in order to determine if the object meets a quality criterion, in particular is tight or leaky or true to size or functional.

A pressure testing unit for pressure testing equipment including a test cell having first and second side walls, a cell frame, a lid pivotally mounted on the first side wall, a first tie rod disposed through the cell frame, a second tie rod disposed through the cell frame, a first impact plate removably secured to proximal ends of the first and second side walls and proximal ends of the first and second tie rods, and a second impact plate removably secured to distal ends of the first and second side walls and distal ends of the first and second tie rods. The test cell may be lengthened by attaching a second test cell thereto. One of the impact plates may be removed from the test cell, and receptacles on the test cell may be connected to receptacles on the second test cell.

The growth/buckle tester relates to a device for testing strength of metal cans. Using the position of the can on top of Belleville spring and expandable rubber bushing, holding by sectional clamps with turning cams and middle central part from outside, permitted create uniform holding and clamping force in horizontal direction. Using chamfers on holding plates and turning cams for holding the testing can vertically create necessary space around the stand for growth/buckle tests. The chamber created inside the can with almost the same volume of volume of air for the test reducing dispersion of measurement values. Cuts around of Bellville spring make path for delivering testing air pressure for the growth/buckle tests. Angle of rotation turning cams depend and control by outside diameter of testing can.

An inspection apparatus includes a chamber and a pressurizer. The chamber includes a space portion configured to house at least a sealed portion of a battery, and an opening portion configured to open a partial portion of the battery other than the sealed portion to an atmosphere. The pressurizer is configured to put the space portion into a pressurized state.
