  • Patent number: 9895855
    Abstract: A tire is described that includes a casing defining a cavity and equipped to receive an object, such as an electronic circuit, for example, through use of a two-part attachment, such as a touch-close attachment, of which a first part is fixed to a wall of the casing and a second part can be joined to the first part when placed in contact with the first part to keep the object on the casing in a service position. The first part of the attachment includes connection elements that are an integral part of the wall of the casing of the tire. The connection elements allow these two parts to have freedom to move relative to each other, thereby limiting the transmission of stresses, which affect the wall of the tire, to the object. The connection elements may be loops of flexible thread formed by the extremities of turns of a coiled thread integrated into the wall of the tire during the tire's manufacture.

  • Patent number: 9862915
    Abstract: The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.

  • Patent number: 9809063
    Abstract: A low compaction cantilevered tire construction is provided which is designed for use at relatively low inflation pressures and which has sidewalls with a relatively uniform bending resistance through the majority of the sidewall. When the tire is placed under high loads at low inflation pressures the sidewall deflects substantially radially and allows the tread portion of the tire to maintain its intended shape thus improving the contact area of the tire and providing a tire having a relatively high contact area and thus relatively low soil compaction for a given loading.
