Abstract: A valve assembly (100, 500) for a pressurised or pressurisable container of an aerosol spray device is disclosed, wherein a valve stem (120) of the valve assembly (100, 500) is moveable between: a closed position in which a first sealing means (144) is biased against a second sealing means (148, 548) by a biasing means (146) such that a housing inlet (112) is not in fluid communication with an at least one valve stem inlet (178, 184); and an open position in which the first sealing means (144) is displaced from the second sealing means (148, 548) by a proximal end (174) of the valve stem (120) such that the housing inlet (112) is in fluid communication with the at least one valve stem inlet (178, 184), wherein, in the open position, a flow path is created from the housing inlet (112), around the outside of the first sealing means (144), and to the at least one valve stem inlet (178, 184).

Abstract: Disclosed is a wrap which is removably attached with a body part of a user to provide compression, and protection. The wrap includes first sensing unit, second sensing unit, movement unit, adjuster unit, and a power source. The first sensing unit senses the physiological state of the user's body. The second sensing unit measures the dimension of the body part of the user. The body part is selected from at least one of: wrist, ankle, lower back, knee and/or combination thereof. The movement unit receives sensed information from first sensing unit, and second sensing unit to support an inflate mechanism and deflate mechanism to provide desired compression to the body part of the user. The adjuster unit configured with the movement unit to engage or disengage the wrap from the body part of the user. The power source which further includes a rechargeable battery powers the first sensing unit, second sensing unit, movement unit, and the adjuster unit.

Abstract: According to aspects of the invention there is provided a remote unit comprising a processor and one or more terminal interfaces, the processor being connected to the one or more terminal interfaces, the terminal interfaces configured for coupling with a set of terminals, wherein the processor is configured to perform quality of service network testing using one or more of the set of terminals over one or more communication networks.

Abstract: A radially expandable building drum, in which is intended for manufacturing an adapter for mounting a tire on a wheel rim, includes a central shaft, a first set of segments, and a second set of segments. All of the segments are arranged circumferentially around the shaft to form a generally cylindrically shaped external face of the drum. The segments of the first set and the segments of the second set face one another axially. The drum is structured to allow a different radial expansion of the segments of the first set in relation to the segments of the second set, between two working positions.

Abstract: A tire includes a carcass ply, two beads, two sidewalls, and a crown reinforcing zone. The carcass ply connects the two beads by way of the two sidewalls. The crown reinforcing zone is positioned radially external to the carcass ply. The crown reinforcing zone includes a plurality of reinforcing strips disposed in at least two layers. The reinforcing strips are coated in an elastomeric composition. A mean overlap between the reinforcing strips of the two layers is greater than 40%. The reinforcing strips are made of a thermoplastic film having a modulus greater than 0.9 GPa, and preferably greater than 2 GPa, in a main direction and in a transverse direction.
