Patent IE-20080563-A1 (IE)
Title: A three-tiered network architecture
Inventor: WHELAN MARTIN
IPC: G06F9/06
Filed: 2008-07-09
Abstract: The present invention concerns a three-tiered network architecture used for increasing adaptability of a processing network and reducing the computational complexity of the processing network. Prior art systems have integrated too many of the functions of the system into a large central processing system. This large central processing system has then become unwieldy to manage and to update to be compliant with new data formats due to the need to re-programme and re-compile the entire central processing system. Data that requires manipulation prior to transmission between programs is manipulated in a stand-alone data connection unit. These data connection units can be used in conjunction with a central processing system to provide an easily adaptable system in which any new data formats are taken care of with a new data connection unit and the existing central processing system. It is far easier to program a new data connection unit than to re-program the large central processing system.

Patent IT-GE960076-A1 (IT)
Inventor: CARTA MAURIZIO
IPC: A61B17/80
Filed: 1996-09-04
Abstract: The invention concerns a process for the production of osteosynthesis plates with a varying thickness to whatever degree. The plates are manufactured by a metal cutting process carried out on a composite structure made by a layer of the material which will form the osteosynthesis plate, bound through a layer of adhesive to a supporting layer with high thermal conductivity and mechanical strength. When the cutting process terminates, the osteosynthesis plate is separated from the supporting layer by heating the composite structure until the adhesive melts or by using a thinner suitable for the adopted adhesive.

The injected oxygen quantity is increased at an accelerated rate immediately following the Al-Si oxidation phase to the oxygen quantity of the principal decarburization phase until the decarburization rate calculated in c) is reached. The decarburization rate is maintained substantially constant for the duration of the principal decarburization phase by the injected quantity of oxygen. The injected oxygen quantity is continuously reduced immediately following the principal decarburization phase so that the decarburization rate decreases continuously in time at a predetermined time constant.
