Abstract: A method for in-line leak testing of blow moulded containers wherein a conveyor line is fed with a continuous stream of blow moulded containers from a blow moulding machine, at least one measuring head is temporarily connected to a first blow moulded container. The measuring head is moved in order to follow the movement of said first blow moulded container which is pressurized by a source of pressurized gas, the source of pressurized gas is disconnected, said at least one measuring head is used to measure the pressure decay therein. The pressure decay is compared with stored data for the pressure decay of acceptable containers and an accept or non-accept signal is generated which implies proceeding or disposal of said first blow moulded container. The measuring head is moved against the moving direction of the conveyor line to a subsequent blow moulded container, and the process is repeated.
Abstract: There is disclosed a test device for testing high-pressure water tightness function of profiled components, comprising a toggle mechanism comprising a drive assembly and a toggle assembly, the toggle assembly comprising a mounting seat drivingly connected to the drive assembly and several toggle levers mounted to the mounting seat; and a carrier stage configured to carry components to be tested; wherein each toggle lever is provided with a carrier stage directly below the toggle lever, the toggle lever is selectively mated to the component to be tested on the carrier stage, and the drive assembly can reciprocally transmit power along the X-axis direction, and when the toggle lever is in a mating state with the component to be tested on the carrier stage, the toggle lever reciprocated linearly along the X-axis direction under driving of the drive assembly to toggle the component to be tested on the carrier stage.
Abstract: A method for testing tightness of container includes placing a bell-shaped test head over a mouth of the container, sealing the container against the test head, accommodating at least a portion of the container in a testing chamber within the test head, increasing a pressure difference between a pressure within the testing chamber and an internal pressure of the container, identifying evidence of matter exiting the container and entering the testing chamber. Typical evidence includes emergence of filling substance into the testing chamber and/or foaming of the filling substance in the testing chamber. Identifying such evidence includes using a camera to monitor either the region of the container or the test chamber for the evidence.

Abstract: The present invention provides an air tightness detection device for an aluminum alloy wheel hub, which is characterized by precision air pressure sensors, a lower clamp, a cone cylinder pressure plate, air pipes, a pressure plate, guide posts, an air inlet pipe, and a compressed gas control and detection system. A technical solution of the present invention has the following advantages that the cone cylinder pressure plate of the detection device reduces the space of an inner cavity of the wheel hub to further reduce inflating volume, thereby increasing detection efficiency; the characteristics of readily availability for preparation, no pollution and low cost are achieved by taking compressed air as a leakage indication gas.
Abstract: Systems and methods for monitoring health of one or more subsystems of a vehicle system are disclosed. At least one sensor can be operatively coupled to a vehicle subsystem having an operational signature and a control system is coupled to the at least one sensor. Using information provided by the at least one sensor, the control system is structured to generate a reference signature of the subsystem during a learning phase and an operational signature of the subsystem subsequent to the learning phase. Systems and methods for identifying the particular subsystem exhibiting degraded performance are also disclosed.

Abstract: Provided is a pinhole inspecting method for suitably inspecting a pinhole in a bottle compared with conventional pinhole inspection. A reference inner pressure (P1) is a bottle inner pressure obtained directly after closing a supply valve (3) after opening the supply valve (3) for only a predetermined time. Whether the reference inner pressure (P1) is over a previously specified first threshold value (Pth1) or not is checked, and when it exceeds the first threshold value (Pth1), airtight status of the bottle is held for a predetermined time, and then a pressure reduction quantity (?P) of the bottle inner pressure from the reference inner pressure is measured after a fixed time. The bottle is judged to have no pinholes only when the value of ?P is not exceeding the previously specified second threshold value (?Pth2).
Abstract: The present invention relates to 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: Apparatus and methods for in-line testing of the internal pressure of flexible containers traveling along a production line at high speeds. The apparatus inspects semi-rigid plastic and thin-walled liquid filled containers by analyzing the output from a load cell that indirectly measures the reaction force applied to a container through the intermediary of a load cell roller that, in turn, supports a flexible belt that directly contacts containers while moving them through an inspection station without interrupting the flow of the production line. Containers are contacted only by a flexible portion of a conveyor belt to minimize structural and aesthetic damage to them that might otherwise occur during the inspection process.

Abstract: A method for testing a vacuum package with regard to seal-tightness, the vacuum package is placed with at least one surface section against at least one contact surface of a vacuum device. A vacuum is generated on a side of the contact surface opposite the vacuum package. A parameter indicative of an air flow through the contact surface in a flow direction away from the vacuum package is measured. The parameter is compared with at least one limit value. A first state is assigned to the vacuum package when the parameter surpasses the at least one limit value and a second state is assigned to the vacuum packaged when the parameter drops below the at least one limit value.
