Inventor: JEAN-MARIE ROMAN
IPC: C08G18/10
Filed: 1991-11-21
Abstract: These composite materials consist of the combination of an organic elastic matrix with a network of quasispherical nonoxide ceramic particles of submicron dimensions with a diameter of between 0.1  mu m and 10  mu m, which are distributed uniformly in the said matrix. They are intended for coating components subjected to phenomena of wear, erosion, cavitation and abrasion, especially in a corrosive medium.

Abstract: The invention relates to a process for preparing fibrinogen of high purity. This process is characterised in that it comprises, starting with cryoprecipitates from blood plasma of animal or human origin, placed in aqueous solution, treating this solution so as to bring it to an ionic strength equal to that of a buffer solution having the following composition:     NaCl 120 mM   Tris 20 mM   pH 8.8 this solution, of adjusted ionic strength, is passed through an anion exchange column comprising an anion exchange gel, for example in the form of beads, based on crosslinked agarose comprising quaternary amine groups, especially at the end of a small spacer arm, for example of the C1-C6-alkylene type linked to the agarose beads, in particular containing about 6% agarose and an elution is carried out using a first eluting solution of the same ionic strength, these conditions making it possible to adsorb at least selectively the fibrinogen onto the said column, which fibrinogen is desorbed using an eluting solution of higher ionic strength at 200 mM NaCl. A fibrinogen of high purity is obtained.

Title: Satellite communication beam switching for digital data - using central unit to control receive-transmit sweep antenna beam position, and synchronising digital information
Inventor: RUIZ BENEDICTO
IPC: H04W28/04
Filed: 1992-04-09
Abstract: Modulation (MOD1...MODN) is applied to carrier signals and applied to a beam forming network (BFN1) and a transmitter (Tss), thence to the antenna elements (A1..Am), transmitting digital information. The central control unit (OBS), receives commands from the input bus (BCC) and sends signals to the beam forming network to shift the antenna pointing to the required direction. The time division multiplexing of digital information and antenna pointing are synchronised. Received signals are received similarly in antenna elements (A'a-A'm) and a receiver (RSS) and synchronised beam forming network (BTN2) to be demodulated. ADVANTAGE - Allows amplifiers to operate in saturation mode with single time multiplexed carrier.

Title: Deceleration indication device for motor vehicle - uses contacts on accelerator pedal and top gear ratio selector to deliver signals to logic circuit that activates braking lights
Inventor: DANIEL MOLENDA
IPC: B60Q1/44
Filed: 1992-04-23
Abstract: The device includes a contactor which detects the return of the accelerator pedal to its rest position to anticipate the application of the brakes.

Title: Destroying suspended particles by pyrolysis - in particular solvents in air from spray-paint facilities to regenerate the active carbon@ fibres
Inventor: GUY MARTIN
IPC: B05B14/49
Filed: 1992-05-14
Abstract: Destroying by pyrolysis a gas such as air containing solvents and volatile components. The polluted air, for example dilution air for the regeneration of active carbon filters, undergoes a treatment process with a number of stages: a first gas flow containing the components to be destroyed in suspension is channelled into a preheating unit (24); it is completely mixed with a second unpolluted gas flow from outside; the two flows join and are recycled in a solvent trap (2) to improve the desorption reaction; this flow, containing all the elements in suspension, is then submitted to a new preheating process (25) which is greater than the first so the pyrolytic oxidation reaction will be complete; the gas flow, cleansed of noxious particles, is cooled before being ejected into the environment. Installation to achieve the above process, with the air output from the solvent trap which acts as dilution air for the regeneration of active carbon filters is channelled through a preheating system and then mixed with a neq air flow, to return to the solvent trap at an appropriate temperature for the total desorption of the said trap. This air loaded with desorbed solvents is then sent to a cross-flow heat exchanger (25) where it is preheated in contact with an air flow from the pyrolytic furnace (21). The preheated air, still containing the solvents and solid particles, is completely oxidised in a number of pyrolytic chambers (23) and is then passed back through the cross-flow heat exchanger to be cooled, before being ejected into the environment. USE - Solvents are removed from the air extracted from spray paint shops (such as those in car plants) by active carbon filters. This process and installation enables the removal and destruction of the solvents from these filters using the same air.
