Abstract: A switch machine for railway and tramway switches or the like, having an enclosure for its operating units of the same size as a tie and adapted to be used like a tie, characterized in that the switch machine has a modular construction.

Abstract: A re-usable modular formwork comprising at least one panel having edge ribs and transversal ribs, each of the ribs comprising two parallel walls perpendicular to the formwork panel and preferably perpendicular to the walls of the rib and to the panel. Said ribs are disposed along the perimeter of the panel and transversally to the panel. Other ribs of smaller height may be positioned diagonally within the square or rectangular areas delimited by the edge ribs and the transversal ribs. Where two or more main transversal ribs and/or edge ribs intersect, these ribs have rounded joints. Centrally in said rounded joints, there is an opening for introducing a containing rod. Other openings may be present on the edge ribs for inserting and locking closing keys.

Abstract: In one embodiment, a golf club of the so called putter type includes a cylinder shaped head having a vertical semi-through hole placed in the middle of the cylindrical surface, a second threaded hole perpendicular to the first hole for the insertion of a screw, and a shaft of adjustable length inserted in the first hole. The shaft includes a first portion inserted in said semi-through hole, vertically and orthogonally relative to said head, and further includes portions that are one opposite to the other and bent at an angle in relation to the first vertical portion, of which an angled upper portion is disposed parallel to the ground when the club is in its position of use, said end in turn supporting a grip formed by two spheres of different diameters, with the inner sphere configured to slide along the shaft.

Abstract: A susceptometer for non-invasive determination of iron concentration in a body, by detecting the magnetic flux variation produced by the body. The susceptometer comprises a heat insulating case (16), containing a support structure that defines a screening region (8, 10). The structure supports an alternating magnetic field source, which is able to generate a magnetic field in the screening region, and at least two magnetic field sensors (4, 6), disposed in front of the field source (2). Means (12, 14) for introducing the body to be measured in the screening region (8, 10), temperature-control means, for stabilizing temperature inside the case, so as to limit relative variation to a predetermined maximum value, and means for processing electric signals indicative of the variation in the magnetic field linked to the sensor, which variation is caused by the screened body, in the screening region, are further provided.

Abstract: The invention relates to a spark-ignition engine with a highly structural compression ratio greater than 15:1, throttle regulation, externally supplied ignition and with direct fuel injection into a precombustion chamber, which is connected to the main combustion chamber via an overflow channel. The fuel is injected into the precombustion chamber during the compression stroke and is ignited by a spark plug located in a manner that is as central as possible.
