A milling tool (1) comprising a tool body (101) having a central rotation axis (C), including a front end (101) and a rear end (102) between which an envelope surface (103) extends, wherein at least one insert seat having an outer border (106) delimiting the insert seat from the front end and the envelope surface is provided, and at least one double-sided cutting insert having an upper side, a lower side, an upper cutting edge (204) and a lower cutting edge (214) radially mounted in an insert seat with the lower side abutting a bottom contact surface. An active upper cutting edge (204a) is thereby provided. At least a part of the lower cutting edge neighbouring said outer border and located behind the active upper cutting edge in a direction of rotation does not protrude by more than 0.5 mm with respect to the outer border, and a distance between said part of the lower cutting edge and said outer border is smaller than 0.5 mm in the direction of rotation of the tool body.

A frictional bolt 40 for frictionally engaging the internal surface of a bore 32 drilled into a rock strata. The friction bolt 40 includes a circular tube 42 which is split longitudinally, and which has a leading end and trailing end and an expander mechanism within the tube towards the leading end. An elongate bar or cable 47 is disposed within the tube 42 and extends between the expander mechanism at one end and an anchor arrangement at the other end. A ring 43 is welded to the trailing end of the tube 42 and the bar or cable 47 extends through the ring 43 into connection with the anchor arrangement. A restrainer member 35 is disposed within the tube 42 adjacent the ring 43 and extends at least partially about the bar or cable 47 and is in engagement with the bar or cable 47. The tube 42 has a weakened region HAZ adjacent the ring 43 and restrainer member 35 extends longitudinally within the tube 42 past the weakened region HAZ in the direction of the leading end of the tube 42. The restrainer member 45 includes a projection 38 that projects through the longitudinal split of the tube 42 for engagement with the facing wall of the bore 32.

A compound roll (20) includes a sintered inner core (22) of a first cemented carbide and at least one sintered outer sleeve (24) of a second cemented carbide disposed around the inner core. The outer sleeve and inner core each have a joining surface (26,28), wherein when the inner core and outer sleeve are assembled each joining surface is brought into contact to form a bonding interface (30) there between. When the assembled sintered inner core (22) and sintered outer sleeve (24) are heated to a predetermined temperature the sintered inner core and sintered outer sleeve are fused together at the bonding interface (30) to form the unitary compound roll (20). In order to reduce the overall cost of the compound roll (20), a lower cost cemented carbide, or a cemented carbide with a lower density can be used for the inner core and fused to a sintered outer sleeve of a virgin cemented carbide, thereby reducing the powder cost and/or reducing the overall mass of the compound roll itself.

NEXTOWER shall introduce a set of innovative materials to boost the performance of atmospheric air-based concentrated solar power (CSP) systems to make them commercially viable. In particular, tower systems are appealing for the great environmental compatibility and offer tremendous potential for efficient (electrical and thermal) power generation. Yet, their industrial exploitation has been so far hindered by limitations in the materials used both for the central receiver - the core component - and for thermal storage. Such limitations dictate maximum working temperature and in-service overall durability (mainly driven by failure from thermal cycling and thermal shocks). Improving the efficiency of a tower system entails necessarily improving the central receiver upstream and possibly re-engineering the whole systems downstream to work longer and at much higher temperature, especially in the thermal storage compartment. NEXTOWER will address this need by taking a comprehensive conceptual and manufacturing approach that will optimize bulk and joining materials for durability at the component level to achieve 25 years of maintenance-free continued service of the receiver and maximum thermodynamic efficiency at the system level. This is made possible through a unique combination of excellence in materials design and manufacturing, CSP full-scale testing facilities brought together in the Consortium, supporting the making of a new full scale demo SOLEAD (in Turkey) within the project. The successful achievement of a new generation of materials allowing for virtually maintenance free operations and increased working temperature shall result in the next-generation of air-coolant CSP highly competitive over other CSP alternatives and sustainable power supply options.
