An acetabular inserter (10) aids a surgeon in controlling the installation of an acetabular cup prosthesis (11) having a central, female aperture (13). The inserter includes an inserter head (20), a housing (12) and a locking mechanism. The housing (12) is attached to the inserter head, the housing enclosing a drive train (14) having, at a far end (134), a prosthesis engaging thread (124), and at the opposite end (42′), a handle (20) which facilitates turning of the drive train by the operator. The locking mechanism is associated with the housing which selectively locks the drive train, and thus the prosthesis, in position. The opposite end (42′) of the drive train has a latch device which enables quick removal from the housing for cleaning and sterilization.

The present invention concerns a convective system for a dryer installation for a passing web, more particularly paper. The convective system 7 is an assembly of an exterior casing 13 for suction of combustion products with opening 14 towards the web, with a first 15 and second 16 suction ducts sucking the combustion products into the convective system 7. The combustion products coming from the first suction duct 15 are guided through the exterior casing 13 to a mixing and blowing device 17. Cold air 18 is mixed in this mixing and blowing device 17 with the combustion products 19, resulting in a gas mixture with lower temperature 20. The convective system 7 also has an internal casing 21 inside the external casing 13. This internal casing 21 has at least one opening towards the web 22 and has also openings 34 allowing gas flow from the mixing device 17 to the internal casing 21 of said gas mixture 20. Under the internal casing 21, there is also a blowing duct 23. The second suction duct 16 is also arranged under this internal casing 21 thereby extracting a second flow of combustion products 24 into the internal casing 21. This second flow 24 of combustion products is then mixed with the gas mixture 20 coming from the mixing device 17, resulting in a mixture of gasses 25 with a temperature that is higher than the first gas mixture 20 and higher than e.g. 350° C. or 370° C., more preferably 390° C. or 410° C., even more preferably 420° C., 450° C. or 500° C. These hot gasses 25 are then blown to the drying web by the blowing duct 23 of the internal casing 21.
