An inflatable device repair kit may include an openable repair packet having a patch surface, a sandpaper surface and a packet interior between the patch surface and the sandpaper surface. At least one tube repair patch may be detachably adhered to the patch surface of the repair packet. An abrasive sanding texture may be provided on the sandpaper surface of the repair packet. A patch cement may be provided in the packet interior of the repair packet. The abrasive sanding texture on the repair packet may be used to smoothen an exterior surface on an inflatable device wall of an inflatable device at a break in the inflatable device wall. The repair packet may be opened and the patch cement in the packet interior applied to the tube repair patch and the tube repair patch applied to the inflatable device wall over the break to seal the break.

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.

A method for welding a first hose end at a joint with a second hose end in a seam that extends on a circumference of the first hose end, the method comprising the steps: applying a protective layer at the joint to an inside of the first hose end; pushing the second hose end beyond the joint over the first hose end; pressing the first hose end and the second hose end together flat at the joint between two first damping jaws that are moved towards each other; welding the first hose end and the second hose end together by two first partial seams while pressed together, wherein the protective layer prevents a welding of the inside of the first hose end; releasing the first hose end and the second hose end from the two first clamping jaws after welding the two first partial seams.

A pyrolysis method and a pyrolysis reactor for recovering silica from a polymer waste material containing silica, particularly a rubber or plastics waste material containing silica, using thermal decomposition for separating silica from at least one non-silica component of the polymer waste material, are disclosed. The waste material is delivered to a pyrolytic chamber, and heated to a decomposition temperature of at least one non-silica component of the waste materiel by microwave radiation. The decomposition temperature is selected such that the at least one non-silica component includes a higher microwave absorptivity than silica.

A one-way valve (10) comprises: a valve housing (100) having a first end portion, a second end portion, a valve housing channel (110), and a stopper projection (108) provided within the valve housing channel (110); a valve body (200) having a first end portion, a second end portion, and a valve body channel (202) in fluid communication with the valve housing channel (110), the second end portion of the valve body (200) being snap-fit to the first end portion of the valve housing (100); and a sealing plug (300) slidably disposed within the valve body channel (202), wherein an inner diameter of the valve housing channel (110) is greater than an inner diameter of the valve body channel (202) and an outer diameter of the sealing plug (300), and a distance between the stopper projection (108) and the second end portion of the valve body (200) is greater than a longitudinal length of the sealing plug (300). A tire repair glue bottle (1) having a one-way valve comprises: a bottle body (20) containing glue; an air intake device (40) attached to the bottle body (20); a bottle lid (50) attached to the bottle body (20); a glue tube (30) provided within the bottle body (20) and having one end connected to the bottle lid (50); and an one-way valve (10), wherein the second end portion of the valve housing (100) of the one-way valve (10) is connected to the other end of the glue tube (30).

A puncture repair fluid container includes: a container body including a storage portion for storing a puncture repair fluid and an opening portion provided at one end of the storage portion; and a cap mounted to the opening portion. The cap includes an introduction path for introducing compressed air from outside; a discharge path for discharging the puncture repair fluid to the outside; a switching valve for switching two paths disposed between the introduction path and the discharge path; and a switching knob for operating the switching valve. A jig for rotating the switching knob is provided, the switching knob is provided with a recessed portion or protruding portion, and the jig is configured to be attachable and detachable to the switching knob, the jig being provided with a protruding portion or recessed portion that is fitted in or to the recessed portion or protruding portion of the switching knob.
