Abstract: A rekeyable cylinder (1) comprising a stator (2) provided with a substantially cylindrical receptacle (3) for a rotor (4). The rotor (4) and the stator (2) are affected by channels (5) for at least one respective pin, movable so that it can slide in them in contrast to respective elastic means. The simultaneous arrangement of the pins partly in the rotor (4) and partly in the stator (2) determines the locking of the rotor (4), and the alignment of a terminal edge of the pins with the interface surface between stator (2) and rotor (4), obtained through the insertion of an adapted key (7) with a contoured profile into an opening (6) of the rotor (4) that faces the channels (5), determines the free rotation of the rotor (4) with respect to the stator (2).

Abstract: Vacuum sterilization process with the application of vapour of a mixture of peracetic acid with hydrogen peroxide and residual gas plasma from atmospheric air, excited by pulsed electrical discharge; operational devices and methods used in the sterilization process, preferably a process of sterilization in vacuum, dry, and at low temperature (room temperature).

Abstract: System for washing and sterilizing endoscopes provided with multiple channels held by a sheath, comprising a machine connected by means of multiple connectors provided with safety valves to at least one case with hermetic closure into which the endoscope is positioned, in which each of the channels of the endoscope is connected by means of a connector, the inner space of the case is connected to at least one additional connector, in such a way as to inject the washing and sterilization liquids and/or the gases for emptying the channels or drying, into each of the channels of the endoscope and into the space of the case, in which the case is also provided with an outlet connector for system circulation, in which the case is detached after the working cycle of the machine and its inner space remains in sterile conditions.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An electric lock with magnetic support of the coupling element, comprising a locking element engaging a selvage, a decoding assembly for a code bearing component, an actuation element, connected to an internal handle and associated with the locking element, and a second actuation element, connected to an external handle and coupled to the locking element by way of an electromechanical device. The actuation element comprises a stem connected to the external handle with a rotating plate and a contrast plate, at an end resting freely on a rotatable sleeve, coupled to the locking element and provided with notches; an electric motor and a slider, aligned with the notches actuatable to perform translational motion, and a magnet supporting a coupling element adapted to enter the notches to rigidly couple to each other the plate, the contrast plate and the sleeve.

Abstract: An electric lock with multiple-function spring, with a locking element, a decoding assembly for a code bearing component, a first actuation element connected to an internal handle, and a second actuation element connected to an external handle both coupled to the locking element by an electromechanical device; the second actuation element comprises a protruding stem that ends with a rotating plate, a rotatable contrast plate that rests freely on a rotatable sleeve coupled to the locking element, the plates and the sleeve being provided with respective notches; the electromechanical device has a motor with a worm screw on its shaft, a slider, coupled to the screw through a spring with one end fixed on the lock body, the central portion engaged on the slider, and the opposite end accommodated between two crests of the screw, and a coupling element for entering notches to couple plates and sleeve.

Abstract: A cylinder lock with a key, the lock having a plug with at least one hole intersecting the keyway. The hole is provided with two shoulders, one whereof lies further outward, the other one lying further inward with respect to the surface of the plug. An auxiliary tumbler is accommodated in the hole and comprises an auxiliary pin, an auxiliary complementary pin and a spring acting by expansion between the auxiliary pin and complementary pin. The tumbler can assume an elongated configuration, wherein the pin and the complementary pin are mutually spaced and axially offset angularly with respect to each other, or a shortened configuration, wherein they are aligned in mutual abutment without axially offset. The key has an elastic element adapted to cooperate with the auxiliary tumbler to allow, with the key inserted, compression thereof to the shortened configuration and disengagement from the notch and rotation of the plug.
