A method and system for applying a sealing agent to a surface (2) of an inner cavity (3) of a pneumatic tyre; the method provides for detecting the weight of the pneumatic tyre (4) before and after the application of the sealing agent to the surface (2); calculating the difference between the quantity of sealing agent applied to the surface (2) and a reference quantity of sealing agent, storing said difference within a short-term memory buffer (24) and a long-term memory buffer (26); determining a short-term compensation factor (K.sub.ST) and a long-term compensation factor (K.sub.LT) and calculating a correction factor (K.sub.EA) using alternately the short-term compensation factor (K.sub.ST) or else the long-term compensation factor (K.sub.LT); and using said correction factor (K.sub.EA) to actuate an applicator device (7) during the subsequent step of applying the strip of sealing agent to the surface (2).

A method for repairing composite components includes installing a plug within a feature defined by a composite component, with the plug being formed from one or more neutral materials. Furthermore, the method includes infiltrating the composite component with an infiltrant to densify a repair region of the composite component, with the plug blocking a flow of the infiltrant into the feature. Moreover, after infiltrating the composite component, the method includes removing the plug from the feature.

A method for sealing and inflating inflatable articles, in particular for sealing and inflating motor vehicle tires, wherein, by means of a compressor which is driven preferably by means of an electric motor, a sealing and pumping pressure is generated, wherein, by means of the sealing and pumping pressure, via a valve and distributor device for sealant and compressed gas and via compressed-air and sealant hoses between valve and distributor device and an entry valve or an inlet nozzle of the inflatable article, a sealant situated in a sealant vessel connected to the valve and distributor device is conveyed into the inflatable article and, at the same time, the inflatable article is inflated to a predefined operating pressure, wherein, by configuration of the corresponding parameters, of the sealant and of the device, in or downstream of the entry valve/the inlet nozzle, the sealant is at least partially atomized to form an aerosol by virtue of the sealant or the sealant-air mixture being converted, in the entry valve or in the inlet nozzle, into a turbulent flow with a Reynolds number Re≥22300.

The invention relates to a compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which can be mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly includes a wheel mount-side transmission component or the hub-side transmission component, which includes a cylindrical cam.

A tire maintenance means (1) is provided, which includes a monitoring module (2) for monitoring the status of a tire; an inflating module (4) for inflating or deflating the tire; a repairing module (5) for filling a sealant to the tire; a control module (3) for maintaining the tire based on a signal from the monitoring module (2). A method of maintaining a tire is also provided.

A free radical cure catalyst composition is provided that includes a free radical cure catalyst present as a paste at 20° C. A cure inhibitor is dissolved in a solvent compatible with the free radical cure catalyst paste to form an inhibitor solution that is mixed into the paste. A filler composition is also provided that includes an ethylenically unsaturated resin, a crosslinking agent; and the free radical cure catalyst composition. A method of repairing a vehicle body is provided that includes an uncured layer of the composition as noted above is applied to a substrate. The uncured layer is modified during a working time of from 8 to 35 minutes. The uncured layer is allowed to cure under free radical conditions to form a cured layer.

A sensing sealant liquid container for repairing an inflatable article, preferably a tyre, comprises a first portion produced by injection moulding and a second portion produced by injection moulding, the first and the second portion being connected to each other to delimit a volume inside which a sealant liquid is retained, an outlet tube for the sealant liquid when the container is pressurized and a sensor for verifying the functional connection of the tube to the inflatable article, and at least one track electrically connected to the sensor and co-moulded on one of the first and the second portion, the track defining a contact releasable electrical connection.
