A check joint structure for a connection of an air nozzle of a tire and a connector of a connection hose of an air compressor, the air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body of the air compressor. The sealant supply can includes an open segment and a supply tube. The connection hose includes a first segment and a second segment. The second segment has a check connector which includes a fitting sleeve, and the fitting sleeve has a threaded orifice, a through orifice, and a projected shoulder. A cylindrical base includes a cylindrical room, a stepped coupling segment, a conduit, and a first stepped portion. A first spring is received into the cylindrical room to abut against the first stepped portion. A valve bolt includes a contacting element fitted thereon.

A damaged glass surface restoring tool comprises a replaceable, hermetically sealed container of glass fluid restoring substance aligned within a vacuum chamber perpendicularly to the glass surface. A method of restoring a damaged glass surface creates a vacuum in a chamber aligned over a crack in the glass and applying to the crack a glass restoring substance before being exposed to external air in a straight line path of application.

The present application relates to a tire repairing system, comprising: an inflation device including an inflation housing and a motor; and a sealant container having a container housing, an air outlet of the inflation device can be connected to an air inlet of the sealant container, wherein the inflation housing is able to connect to the container housing in such a way that the container housing acts as a pedestal and the inflation housing is arranged on the container housing.

A coke plant includes multiple coke ovens where each coke oven is adapted to produce exhaust gases, a common tunnel fluidly connected to the plurality of coke ovens and configured to receive the exhaust gases from each of the coke ovens, multiple standard heat recovery steam generators fluidly connected to the common tunnel where the ratio of coke ovens to standard heat recovery steam generators is at least 20:1, and a redundant heat recovery steam generator fluidly connected to the common tunnel where any one of the plurality of standard heat recovery steam generators and the redundant heat recovery steam generator is adapted to receive the exhaust gases from the plurality of ovens and extract heat from the exhaust gases and where the standard heat recovery steam generators and the redundant heat recovery steam generator are all connected in parallel with each other.

Fluid leak repair kits are described comprising a putty, self-amalgamating tape, and a composite material for use in encompassing the self-amalgamating tape. The composite material comprises a flexible sheet or tape and a matrix component for binding the flexible sheet or tape. The matrix component comprises a resin or water-activated matrix component which, when cured, forms an outer shell.

The invention relates to a device for sealing pneumatic tires by means of sealing liquid, having a sealing liquid container having an air inlet opening for connection to a compressor and an outlet opening for the discharge of an air/sealing liquid mixture into a pneumatic tire to be sealed, the sealing liquid container having at least two chambers in which components of the sealing liquid that are reactive to one another are stored separately, the chambers being separated from one another by a closed connecting element which can be opened via a pressure and/or an air flow from the air inlet opening to the outlet opening.

An aerial drone for repairing holes or punctures in a membrane on a roof, characterized in that the aerial drone comprises at least one camera for recording a section of the membrane, an applicator adapted to apply material onto the section of the membrane, wherein the applicator is controllable wirelessly from a different altitude and/or the ground.

A method of repairing erosion on a wind turbine blade while on a wind turbine includes placing a scanning device on an erosion zone. The device scans the erosion zone to gather an image and/or digital data. A printing system deposits a material according to the image and/or digital data. The repair system may include a frame such that scanning and/or depositing are with respect to the frame. A processing system interprets the image and/or digital data and produces an instruction file. Depositing the material may include depositing the material according to the instruction file. An unmanned aerial vehicle may be operated to position at least one of the scanning device and the printing system on the wind turbine blade. Alternatively, a rope/wire system may be operated to lower at least one of the scanning device and the printing system along the wind turbine blade.

The object of the present invention is to provide a tire sealant and tire repair kit having excellent injectability.
