An electromagnetic shield and an arrangement for shielding electric components against RF/EM interference. In the arrangement a frame is placed on top of a printer circuit board (PCB) and a display is placed on top of the frame. The interior surfaces of the display, the frame, and the PCB comprise an RFI/EMI shield. Thus the lids know in the art are omitted from the shield according to the inventi...

Metallurgical reactor for the production of cast iron, consisting of a metal casing internally lined, at least partially, with refractory material and provided, in the region of the top closure, with a duct through which high-temperature ferrous material is introduced, said reactor being equipped with a first series of lances for injecting the comburent gas, which are suitably directed and arrange...

Digital television signals comprising a plurality of elementary binary streams representing respective TV programs are multiplexed into a single, low-capacity transport stream, which also incorporates packets containing PSI/SI tables, PCR packets and null packets. The transport stream is then modulated and transmitted to a plurality of terrestrial stations for re-broadcasting from terrestrial aeri...

A micro-actuator includes a shape memory thin film (2) having one end (2a) fixed to a substrate (1) and one remaining part (2b) which, at room temperature, is in the martensitic phase and assumes a curly-configuration, whereas at a higher temperature than a threshold value it changes to the austenitic condition, wherein the film is completely stretched upon the substrate.

A unit (8) for clinching metal sheets (4) has a preclinching tool (48) and a clinching tool (49), which are fitted to a frame (16) which is slid by a pneumatically powered guide and slide device (17) between a forward work position and a withdrawn rest position; the frame (16) supports a shaft (10) operating three cam and tappet devices (32, 60, 61), which lock the frame (16) in the forward work p...

The mobile unit (4) contains trays of meals and has a top with an opening (430) with a closing valve (431) and which can be located beneath the wall (3) mounted unit (2) having hot air and/or cold air delivery systems through an opening (23) and selection valve (230). The wall unit is mounted on two parallel rails on which it is moved vertically by an electric motor (200) and a central toothed or...
