A method for installing a rotor (3) excited by permanent magnets into an electrical machine (13) using a support, the electrical machine including a stator (2) and a rotor (3). The support contains a shaft (4) supporting the rotor (3). The rotor (3) is rotated, or the shaft (4) supporting the rotor is rotated, whereupon the rotor (3) is moved to its operating position with the help of mutually cor...

The invention relates to a nanofiltration process for enriching and concentrating a neutral organic compound into the permeated liquid with negative retention.

An associative memory device includes a magnetically responsive layer adapted to store a representation of a pattern, the magnetically responsive layer includes magnetic nanoparticles as a magnetically active component. The magnetic nanoparticles of the associative memory device are dispersed in a solvent with variable viscosity, and the magnetically responsive layer is a layer of ferrofluid.

The invention relates to a system for controlling the ignition of a motor vehicle, which system comprises: a control member (2) which is manoeuvrable between a switched-off position, in which the control member (2) keeps the ignition switched off, and a switched-on position, in which the control member (2) keeps the ignition switched on, and a manually manoeuvrable operating member (3), by means o...

A method of coating a endovascular device that includes coating of a tubular body's surface by at least a thin layer (s) of a inert and biocompatible titanium based material. This method is performed by the following steps in succession: Deposition of a first Titanium layer ( 21 ). First nitrogen treatment of said first titanium layer ( 21 ) by transmission of high ionic currents on the substrate ...

A device for the high-speed drilling of boards for printed circuits and the like. The device has a support, a drill head with an associated mandrel and a workpiece-pressing device mounted on the support, which can be displaced relative thereto towards and away from the board to be drilled. At least one actuator is interposed between the support, the drill head and/or the workpiece-pressing device ...

A device for the high-speed drilling of boards for printed circuits and the like. The device has a support, a drill head with an associated mandrel, and a member for locking and driving a drill bit in the mandrel. The mandrel is actuated by a compressed air turbine and has an optical encoder for encoding the speed of rotation of the turbine and generating a signal representing this speed. The sign...

A gas injection system provides an injecting device (10) mounted in a two stoke engine (20) and facing a combustion chamber (23) in a engine head (24). The injection system, which comprises a reservoir (1) for storing the gas, feeds (2,3,4) the injecting device (10) and is connected (5) to an electronic control unit (6). The injecting device has an electrovalve (11) for distributing the gas and a ...

A highly stable aqueous solution having a molecular cluster with dimensions which are small enough to ensure substantial chemical-physical stability thereof for a relatively long time. To prepare the solution a fluid treatment device is used, which comprises at least one chamber (7) and at least one anode (4) and one cathode (3) arranged in the chamber (7). The anode (4) and cathode (3) are at lea...

This invention concerns a multi-layer skin product with thermoregulating properties showing a layer in technological material with thermoregulating properties, put between an internal and external layer, both being of skin. The invention concerns also a process to make a multi-layer product and the use of the multi-layer product as defined earlier for the making of clothing items.

The device has an actuator assembly (48) adapted for moving an abutment assembly between a locating position and an inserted position, where the abutment assembly includes two abutment members (38, 40). A sensor is mounted to one of the two abutment members, and is adapted for detecting distance between a portion of a workpiece (16) and one of the two abutment members. A controller (49) includes a...
