Pigments comprising chemochromic metal oxide microparticles or nanoparticles the surfaces of which are superficially coated with nanoparticles of catalyst material. The pigments are prepared by mechanical or wet chemical processes.

Method of making a hydrogen sensing pigment

A remotely readable hydrogen detector is in the form of a tag or card that can be worn on clothing or mounted on a variety of surfaces and can be monitored from a distance for the presence of hydrogen gas. It includes a hydrogen sensor device, which changes in electrical resistivity in response to being exposed to hydrogen gas, that is incorporated into an electric detector circuit, which detects changes in resistivity of the sensor device, and, when such change in resistivity indicates the presence of some predetermined concentration of hydrogen gas, the electric circuit outputs a signal or state that indicates the presence of hydrogen to a transceiver circuit, which can transmit that information to a remote receiver or interrogator/reader via an antenna in the sensor device.

Monitorable hydrogen sensor system

Disclosed is a pigment that changes color upon exposure to hydrogen sulfide gas. The pigment may be ground or otherwise reduced to small particles and used in coatings, dyes, paints or inks. Potential applications for paints and inks include the production of warning indicators for the presence of hydrogen gas in areas where such presence may pose a hazard. Warning decals may be printed with pigmented ink and posted in areas of potential hydrogen hazard. In the presence of hydrogen sulfide gas, the decals can display a warning by causing a change in the color of a printed message. Objects may also be coated with pigmented paints so that if a hydrogen sulfide leak occurs from within or nearby the object, the color of the object changes to provide a warning of the presence of leaked hydrogen sulfide. Example applications of such painted objects include any industrial process containing hydrogen sulfide.

Hydrogen sulfide indicating pigments

A hydrogen gas indicator system that provides various substrate materials () that support hydrogen gas sensor () materials with discrete indicia () that provide information separate from any change in the physical properties of the hydrogen gas sensor itself.

Hydrogen gas indicator system

A steering column safety device for use in a motor vehicle having a steering wheel for communicating steering torque to a steering mechanism, and having a collision sensing assembly for sensing a collision, includes a hollow cylinder having a top end and a bottom end, the top end being sized and configured for fixed, torque-transmitting connection to a steering wheel; a piston residing within the cylinder for sliding, telescopic reciprocation between an extended position and a collapsed position; an elongated rod with first and second ends, the first end being secured to the piston and the second end being sized and configured for fixed, torque-transmitting connection to the steering mechanism; structure for transmitting torque between the cylinder and the rod; a sealing assembly for sealing the hollow cylinder to define a fluid-tight cavity within the hollow cylinder between the piston and the top end of the cylinder, the fluid-tight cavity containing prior-to-collision pressurized gas; and, a mechanism to rapidly open the sealing assembly in response to a signal generated by the collision sensing assembly, thereby permitting movement of the hollow cylinder from the extended position to the collapsed position.

Motor vehicle steering column safety device

A collapsible steering column for a motor vehicle has an elongated hollow cylinder slidably mounted on a piston while also fast to the piston for rotary movement. The space between the interior wall of the cylinder and the piston is sealed in a gas-tight fashion. A head is attached to the top of the cylinder. The head has a frangible seal hermetically secured inside it so that the top of the piston, the interior wall of the cylinder and the seal define an air cavity. The cavity is under pressure such that the cylinder is supported by a column of pressurized gas. A coil spring inside the cylinder urges the piston and the bottom of the cylinder apart. The seal has a bore in which resides an explosive compound. Lead lines connect the explosive compound with an electronic collision sensor, which is located in the front of the vehicle. When a collision occurs, the sensor sends an electronic signal which ignites the explosive compound and fractures the seal permitting the gas to escape from the cavity causing collapse of the cylinder. The vehicle's steering wheel is secured to the top of the head, and the piston is connected by way of appropriate linkages to the front wheels of the vehicle so that axial rotation of the cylinder, by way of the steering wheel, causes the front wheels to turn in accordance with normal vehicle operations. An air bag stowed in the steering wheel may be connected to the top of the head to capture the air released from the cavity providing additional protection to the occupant.
