A graphene material prepared using waste tires and a preparation method thereof. Waste tires are crushed to 30-200 meshes to obtain tire powders. The tire powders are mixed with KOH or an aqueous solution of KOH to obtain a homogeneous mixture. The mixture is dried at 50-90° C. for 12-48 hours, heated and calcinated in a tube furnace under a protective gas for 1-48 hour to obtain a black lump. The black lump is washed with distilled water, dilute hydrochloric acid or dilute sulfuric acid for at least 3 times, and then washed with deionized water for at least 3 times to obtain a black powder. The black powder is dried to obtain the graphene material. The graphene material has a three-dimensional structure composed of oligolayer graphene intertwined and connected with each other, has a high crystallinity, is not easily agglomerated, and thus can maintain nano-effect of the graphene material.

A method of recycling tires comprising the comprising the steps of: placing tires and/or pieces of tires within a casing or mold, applying a binder (e.g. adhesives and/or pining with screws, nails, nuts and bolts, pins, wire and steel or nylon bands etc) to the tires and/or pieces of tires so that the tires are bound together; applying a reinforcing means to the tires and/or pieces of tires (e.g. fitting the reinforcing means around, in between and/or through the tires etc); and melting or pouring an encapsulating means over the top of the tires and reinforcing means to encapsulate them inside the casing or mold and the encapsulating means; and causing or allowing the encapsulating means to set such that a recycled product is formed.

The tool which contains: a support, and an arm bearing a strip extrusion member and a strip applicator roller, wherein the arm is articulated with respect to the support about a first axis parallel to a geometric axis of the roller and about a second axis tangential to a circumference of the roller, of the first and second axes at least one passing through a centre of gravity of the arm.

A conductive terminal structure for a piezoelectric device used as part of a tire mountable apparatus is provided. Unlike known electrical connection structures which include a plurality of conductive terminals that are all exposed through a single insulating layer of the piezoelectric device, such as a top layer of the piezoelectric device, the electrical connection structure can be arranged in a one up, one down configuration. In this configuration, at least one conductive terminal is exposed through a top insulating layer of the piezoelectric device. In addition, at least one conductive terminal of a piezoelectric component is exposed through a bottom insulating layer of the piezoelectric device. The electrical connection structure can be used in combination with a connector assembly design to preserve the integrity of the electrical connection between the electrical and mechanical connection structure and a printed circuit board.

A cap unit for puncture repair comprises a check valve 6 for preventing a backflow of a puncture repair liquid supplied from a bottle container 2.
