|20150191934||REKEYABLE CYLINDER - A rekeyable cylinder (||07-09-2015|
|20090293564||Lock and Associated Key - A lock with associated key, of the type comprising a stator provided with a substantially cylindrical longitudinal cavity for accommodating a rotor with a longitudinal recess for the insertion of a coded key. The rotor and the stator comprise a plurality of channels which accommodate respective pins, complementary pins and optional elastic elements. At least one of the pins has at least one substantially lateral protruding tab, whose upper edge is suitably contoured. The key has a cross-section that is complementary to the cross-section of the longitudinal recess when the pins, at the regions aligned with the tab, are in a configuration for disengaging the stator and the rotor, accommodating with contact the end of the pins in respective coding recesses and the contoured rim of the corresponding tab on complementarily shaped portions.||12-03-2009|
|20090272161||Cylinder and Associated Key - A cylinder with associated key, comprising a stator provided with a longitudinal cavity for accommodating a rotor with a longitudinal recess for the insertion of a coded key. The rotor and the stator comprise channels for accommodating respective pins, complementary pins and any elastic elements. The rotor comprises at least one second passage, the passage and the cavity accommodating at least one respective movable peg, whose head rests against the blade edge of the key when the key is inserted in the recess. The key is provided with suitable contoured regions on its blade edge at the surfaces that face said pegs when inserted in the recess. Each peg has its base inside the respective cavity so as to block the rotation of the rotor with respect to the stator when a key lacking the corresponding contoured regions is inserted.||11-05-2009|
|20090123341||STEAM STERILIZING SYSTEM - A steam steriliser is described wherein the means of generation of the vacuum is a vacuum pump functioning in conditions of saturated or almost saturated steam at high temperatures, without a cooling system, and comprising a circuit of lubrication with a tank, wherein a lubricant fluid circulates, resistant to high temperatures and with high anti-emulsifying power, with means of filtration able to separate the steam from the lubricator fluid.||05-14-2009|
