A method for separating composite materials and mixtures, in particular solid-material mixtures and slags, and to a device for carrying out said method. The method for separating composite materials and mixtures comprises the step of transporting the composite material or the mixture through a separating device. The composite material to be separated or the mixture to be separated is excited by mechanical impulses as it passes through the separating device and is thereby separated. The device (1) for carrying out the method comprises a drive unit (21) for driving a rotor element (32), which is connected to a bearing/shaft unit (22) and which is part of a rotor unit (31). The rotor element itself has at least one rotor tool (33) and each rotor tool has at least one rotor tool component (34) and is surrounded by a stator element (42), which is part of a stator unit (41). The stator element itself has at least one stator tool (43) and each stator tool has at least one stator tool component (44). The rotor element and the stator element are substantially cylindrical.

A motor vehicle with a compressor assembly for the supply of a pressure medium to a tire cavity of a tire of a motor vehicle. The compressor assembly has a compression chamber which is rotationally fixed in relation to the motor vehicle wheel, and the compression chamber and the tire cavity are connected via a fluidic connection for the conveying of a pressure medium from the compression chamber into the tire cavity. A tire sealing device has a sealant reservoir with a first connection fluidically connected to a tire cavity of a tire of the motor vehicle to be repaired, and a second connection fluidically connected to a pressure medium source secured to the motor vehicle. The sealant is conveyed out of the pressure medium source into the tire cavity of the tire to be repaired by means of the pressure medium.

Display assemblies as disclosed herein are configured for attachment with a vulcanized rubber article and are provided in the form of different material layers. Display assemblies generally comprise one or more display layers of elastomeric material configured to provide a desired display indicia, an intermediate layer formed from an elastomeric material different from that of the one or more display layers, and an adhesive layer wherein the intermediate layer is interposed between the adhesive layer and the one or more display layers. The one more display layers may be configured to act together or separately to provide a desired display indicia to provide a desired visual display or feature on the surface of the vulcanized rubber article, which may be a sidewall surface of a tire.

A pyrolysis method and a pyrolysis reactor for thermal decomposition of polymer waste materials, particularly rubber and plastics waste materials, using a fast pyrolysis process, are disclosed. The waste material is delivered to a pyrolytic chamber, and is heated to a decomposition temperature of the waste material by microwave radiation.

A method for repairing a tire is provided that includes: (a) providing a reamer, a knife, an insertion tool forming a receiving opening, a plugging strip, and vulcanizing fluid; (b) inserting the reamer into a puncture hole of a tire to clear debris; (c) applying the vulcanizing fluid; (d) inserting the plugging strip into the insertion tool; (e) inserting the insertion tool with the plugging strip into the puncture hole to cause the plugging strip to fold into the puncture hole mixed with the vulcanizing fluid to bond the plugging strip and the tire; (f) removing the insertion tool from the puncture hole causing a middle portion of the plugging strip to fold internally forming a four-layer seal within the puncture hole; and (g) cutting the plugging strip from the insertion tool and the excess portions of the plugging strip with the knife.

An anti-spray joint structure of a connection hose of a vehicle air compressor, the vehicle air compressor contains: a box, a sealant supply can, and a connection hose. The box includes a body accommodated in the box and started by a power supply to produce compressed airs. The sealant supply can includes an open segment for accommodating chemical sealant, and the sealant supply can includes a supply tube arranged on the open segment. The connection hose includes a front connector and a rear connector. The rear connector is an anti-spray joint structure and includes a first segment and a second segment removed from and connected with the first segment, and the first segment is connected with the second segment which has a channel of different sizes and shapes so as to be applicable for different tires and to avoid eruption of the chemical sealant.

An inflatable device repair kit includes a tube repair patch, patch cement and an abrasive sanding textured surface in a single unitary package. The 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 repair patch includes a composite material to repair a a repair target of a composite material. The repair patch includes bonding surfaces which face a bonded surface of a counterbored hole formed in the part to be repaired, and are bonded to the counterbored hole; and an opposite surface opposite to the bonding surfaces in a thickness direction. The opposite surface has a curved plane with a first surface side curvature radius protruding toward the opposite surface in a cross section cut along a plane intersecting an axial direction in the opposite surface. The bonded surface has a curved plane with a second surface side curvature radius protruding toward the bonding surfaces facing the bonded surface in a cross section cut along a plane intersecting an axial direction in the bonded surface. The first surface side curvature radius is smaller than the second surface side curvature radius.
