Schrader | Date: 2015-07-17

A safety valve releases a fluid in the event of a fire. To do so it comprises a valve shutter in a body for opening or closing a pipe containing the fluid. A first spring is kept under tension against heat-sensitive means for releasing the valve shutter ROM when the tension is released by the sensitive means. The sensitive means comprise a piston acting on the first spring, a pipe being connected to a chamber delimited in the body ROOM by the piston on the opposite side to the first spring. The pipe and the chamber contain a pressurized control fluid so that the piston keeps the first spring under tension. The pipe is made of a material capable of melting at a predetermined temperature so as to release the fluid in the event of a fire around the pipe.

A safety valve releases a fluid in the event of a fire. To do so it comprises a valve shutter (12) in a body (10) for opening or closing a pipe containing the fluid. A first spring (14) is kept under tension against heat-sensitive means (15) for releasing the valve shutter (12) when the tension is released by the sensitive means. The sensitive means comprise a piston (151) acting on the first spring (14), a pipe (153) being connected to a chamber (152) delimited in the body (10) by the piston (151) on the opposite side to the first spring (14). The pipe (153) and the chamber (152) contain a pressurized control fluid so that the piston (151) keeps the first spring (14) under tension. The pipe (153) is made of a material capable of melting at a predetermined temperature so as to release the fluid in the event of a fire around the pipe (153).


A tire monitoring device comprising a sensor for monitoring a tire parameter and a first controller for controlling the operation of the device. A measurement apparatus is provided for generating parameter measurement data from the sensor output signal. A second controller is provided for controlling the operation of the measurement apparatus. The second controller communicates parameter data to the first controller based on the measurement data. The device is particularly suited to monitoring tire pressure and detecting tire burst events.

A tire pressure monitoring system comprising a tire pressure monitoring device for mounting on an internal surface of a tire and including a pressure sensor for monitoring the fluid pressure in the tire. The system has an RFID tag located on the tire separately from the tire pressure monitoring device. In response to detecting a tire pressure event from monitoring the fluid pressure of said fluid, the tire pressure monitoring device causes the RFID to transmit data, which is received by the tire pressure monitoring device.


A tire pressure monitoring device for a wheeled vehicle that is capable of detecting vehicle motion from the output of a pressure sensor. The device determines from the output signal an indication of the power of the signal, for example the variance of the signal, and detects if the vehicle is stationary or in motion depending on the determined indication of power. The device may determine that the vehicle is in motion if the determined indication of power exceeds a threshold value.

A device for a leakproof air-conditioning fluid circuit. A body includes a conduit having a foot at its base, coupled to a communication orifice in the periphery of a tube. A welding is made between an interior part of the base of the foot and a corresponding part of a tube having an orifice. An internal semi-cylindrical a portion of the base of the foot features, around the discharging conduit, a part in the shape of a skirt, formed by two straight or curved segments which together define a semi-cylindrical cradle in the interior wall of the tube. An orifice comprising a whistle-shaped notch in the back of the tube, comprises two complementary segments.

Methods, systems, and devices are provided for tire pressure detectors that may operate according to one of two or more selectable frequencies. Tire pressure detectors may include an RF section to modulate pressure information from a pressure sensor onto an output signal. The frequency of the output signal may be selectable from two or more frequencies based on a frequency required by a vehicle that the tire pressure detector is to be used with. An RF matching circuit may be coupled between the RF section and an antenna, with an impedance of the RF matching circuit selected based of the frequency of the output signal. Such impedance matching may provide a constant power level output from the tire pressure detector independent of the frequency of the tire pressure detector transmissions.

O4S (=Organic for Surfactants) has been primarily designed to address a critical necessity of the European Natural Cosmetic Sector which is lacking a sustainable source of surfactants (Surface Active Agents) that can be considered natural and are of certified organic origin to meet the growing market demands. This development will provide the natural cosmetic sector with an alternative to replace the current use of chemically-derived surfactants from oleo-chemical feedstocks. One of their main applications is in personal hygiene products representing 40% in volume of the cosmetic ingredients used in the EU. This work will optimize the production of natural bio-surfactants by fermentation to achieve industrial efficiency and economic yields by using organically certified sources (e.g. post harvest loses by-products from primary process). The proposed work offers an opportunity to achieve the full utilization of organically certified raw materials increasing the efficiency of the European Organic Farming Systems. Scientific objectives are: 1) To investigate supply of raw materials from waste streams or by-products to lowers the initial costs; 2) To develop scientific knowledge on the interdependencies of the various process parameters and substrate properties ; 3.)To establish of a database of compound characteristics, stability and performance for suitable applications. Further, the overall technical objectives are to define the characteristics of the product to meet the organic certification standards and the performance requirements for their application in the natural cosmetic industry. This will be followed by the specification, optimization and scale-up of an appropriate industrial bio-process for bio-surfactant production (up to 1 m3 to 10 m3) by developing an integrated fermenting and in-situ removal system. Further, a technology platform for product information, formulation and applications will be created for the benefit of the SME-AG members.

A tyre monitoring apparatus comprising a monitor installed on a tyre and a pulse width measuring apparatus for measuring the width of pulses produced by the monitor. The pulse width measuring apparatus comprises a frequency analyzer for producing a frequency representation of the pulse, a signal processor for determining a minimum value of the frequency representation, and a pulse width estimator that inverts the minimum value to produce a measurement for the pulse width. The tyre monitoring apparatus uses the pulse width measurement as an indication of characteristics of the tyre.


An inflation device for a wheel with a pneumatic tire. A valve having a seat carried by a body and a head separates a chamber from an output connector. The head is movable within the chamber between a closed position wherein it is in abutment on the seat and an open position wherein it is separated from the seat so as to put the radial openings into communication with the output connector. The head is elastically held in the closed position against the seat so as to allow lifting of the head when the pressure in the output connector is greater than a predetermined threshold.
