Abstract: A method for tightness control of a filling-sealing unit (1) for containers (9) is described. According thereto, a pressure chamber formed at the filling-sealing unit is sealed by way of a first seal around a sealer that is movable therein and by way of a second seal around a pressure supply that is movable therein. According to the invention, a third seal formed for sealing the pressure chamber around a container neck finish is sealed from the outside with an attachment, a positive pressure and/or negative pressure is generated in the pressure chamber, the pressure line used for this purpose is closed, and then a pressure profile in the pressure chamber is measured. This allows a leakage to be selectively detected at the first and/or second seal and be distinguished from a leak at the third seal.

Abstract: A dummy container for controlling a container filling device includes a base, a housing, a locking mechanism, and an actuating mechanism. The housing is attached to the base and is movable in view of the base between a first extended position and a second collapsed position. The housing defines a fluid inlet extending into a pressure chamber. The locking mechanism is arranged between the housing and the base allowing locking of the housing in the first extended position in view of the base. The actuating mechanism is designed to release the locking mechanism between the base and housing upon a pressure increase in the pressure chamber, thereby triggering the movement of the housing into the second collapsed position in view of the base.

Abstract: A system and method for monitoring the levels of product in a chemical dispensing system. A probe assembly is operatively disposed in a container holding product to be dispensed. A detection circuit including an oscillator sensitive to the impendence coupled to the detector is selectively coupled to the probe assembly and produces a signal in response to the impedance of the probe assembly indicating if the level of product in the container has dropped below the probe assembly. The probe assembly includes conductive probes formed from corrosion resistant material infused with carbon and separated by an angle. The level of the first and second conductive probes is adjustable to provide control over the level of product to be detected. Multiple probe assemblies may be selectively coupled to the detection circuit in a repeating sequence by a multi-probe monitoring unit to allow monitoring of multiple containers by a single remote alarm.

Abstract: A detection membrane is joined to a first surface of an electrolyte membrane. After the detection membrane is hydrogenated, oxygen is supplied to a space facing a second surface of the electrolyte membrane. If the electrolyte membrane has a defect, oxygen leaks to the first surface, resulting in a change in resistance of the detection membrane owing to dehydrogenation of the detection membrane. The defect is recognized by this change. An air electrode is joined to the second surface, and an electric circuit is connected between the detection membrane and the air electrode. After hydrogenating the detection membrane and ionizing oxygen supplied to a space facing the air electrode, oxygen ions permeate through the electrolyte membrane and dehydrogenate the detection membrane. Uniformity of the oxygen ion conductivity is examined by measuring resistance of the detection membrane, which varies depending on the amount of oxygen ions, for each region.

Abstract: An inspection machine for inspecting the volume of liquid contained by a bottle filed to its defined fill height. A head is lowered and has a sealing plate which seals the open finish of a bottle. A fill tube assembly is part of the head and continues to be lowered until a level sensor is located to sense liquid at a pre-fill level. High and low pressure water lines which are a part of the fill tube assembly are operated to fill the bottle to the pre-fill level. The sealing plate is released and then the process is repeated lowering the sensor to the post-fill level and operating only the low-pressure line to fill the bottle to the post-fill level. The total liquid filling the bottle is then computed.

Together with the covering hood (19), the latter forms a sealed testing chamber (13). A vacuum is produced in the latter, with the consequence that the packages experience deformation, specifically the cups (11) experience deformation of a closure film. Non-sealed cups (11) are identified and separated out.

Abstract: A leak detection system determines whether a container has a leak or an aperture by attempting to draw a vacuum in the container and determining whether a vacuum has been created in the container. If a vacuum can be created in a container, this indicates that the container has a leak. Conversely if a vacuum cannot be created in the container, this indicates that the container does not have a leak. The leak detection system preferably includes a conveyor system for moving a container and a sensor for sensing the pressure in the interior of the container through an opening in the top of the container. While the sensor is sensing the pressure in the interior of the container, a vacuum pump pulls air from the region around the exterior of the container. If the container has an aperture, a vacuum will be created in the container and will be noted by the sensor.

Abstract: A testing apparatus for cigarettes or the like has a rotary drum having axially parallel flutes for cigarettes, at least one ring-shaped carrier which is adjacent to one end and is driven at the speed of the drum about an axis which makes a small acute angle with the axis of the drum so that successive increments of the carrier approach the respective end of the drum during travel toward a testing station and move away from the drum during travel beyond the testing station. The carrier supports engaging elements in the form of pins or elastic sleeves which engage the adjacent ends of cigarettes during travel past the testing station. The pins can penetrate into relatively soft fillers of cigarettes and thereby cause a transducer to produce signals which are used for segregation of the respective cigarettes. The sleeves can engage the ends of wrappers of cigarettes during travel past the testing station to admit into the fillers a pressurized testing fluid or to draw a testing fluid through the fillers.
