Abstract: A package for abrasive wheels is provided. The package comprises a base providing an inner space between a side surface, an open end having a diameter Dopen and a closing plane end having a diameter Dclosed, the inner space being adapted to contain stacked abrasive wheels having a diameter Dwheel, the side surface having a projecting portion having a diameter Dproj, that projects from the closing plane end; and a cover configured to couple to the base at the open end so as to close the inner space, the base and the cover insulating the abrasive wheels against atmospheric agents when coupled, the cover comprising a projection shaped to define an annular plane portion having an inner diameter Din and an outer diameter Dout.

Abstract: A protective helmet having a shell which at least partially delimits a head-receiving cavity is provided. The helmet includes an electronic assembly mounted to the helmet shell and having at least one controllable setting. A face-protecting member is mounted to the helmet shell; wherein the face-protecting member comprises at least one panel tab. The panel tab is selectively depressible to cooperate with an actuator mounted to or formed integral with the helmet shell and operatively coupled to the electronic assembly to adjust the at least one controllable setting upon depression of the at least one panel tab.

Abstract: A method for manufacturing a workpiece including a first metallic component and a second metallic component, the method comprising: welding the first metallic component to the second metallic component; performing passivation measurements on the workpiece at a plurality of spaced apart locations; creating a record of the passivation measurements on a server arrangement; making the record created in the server arrangement available to a purchaser of the workpiece.
