Patent EP-0384859-A1 (EP)
Inventor: LAHARY PIERRE-YVES
IPC: C08G69/28
Filed: 1990-02-19
Abstract: Process for the preparation of amorphous or semicrystalline semiaromatic (co)polyamides from an acidic reactant comprising at least one aromatic dicarboxylic acid containing from 8 to 18 carbon atoms, from an amino reactant predominantly comprising an alkylpentamethylenediamine and optionally a catalyst. 
<??>In accordance with this process, the reactants are polycondensed by operating in an autoclavetype closed system according to a protocol comprising the following stages: a stage 1 of distillation of the water present in the reaction mass under constant autogenous pressure, then a stage 2 decompression to atmospheric pressure and a stage 3 of finishing, care being taken that, on the one hand, water is added initially to the reaction mass and, on the other hand, the distillation in stage 1 is conducted under particular conditions of temperature (temperature at the beginning of distillation T1 between 160 DEG C and 190 DEG C) and of autogenous pressure (between 0.5 and 1.2 MPa). 
<??>With such a process, the losses of amino reactant (by entrainment in the distillates and by cyclisation) are significantly reduced.

Abstract: The apparatus comprises an electrically conductive cathode (3) having an active surface which has at least one island which is not receptive to deposition. This island (4) is embedded in the cathode and has an outer face situated flush with the active surface of the cathode. This island may be formed in a hollow arranged either in the active surface of the cathode or in a conductive layer deposited onto this active surface. The island may be formed by localised deposition or by continuous deposition and selective removal depending on the desired pattern. A metal layer is formed by electrodeposition on the cathode thus prepared and the perforated sheet (1) is then detached. <IMAGE>

Abstract: An optical isolator comprising a polarizer, an analyzer, a Faraday rotor and a permanent magnet for magnetizing the Faraday rotor and inducing a Faraday effect. Degradation of isolation characteristics occurs near a critical temperature (0 °C or 70 °C) of a practical temperature range of from about 0 to 70 °C if adjustment and assembly are made in such a manner that maximum isolation is accomplished at the ambient temperature and for the wavelength used for the assembly. Therefore, the temperature position of maximum isolation is controlled by assembling the isolator at room temperature and for a wavelength which is shifted by a very small wavelength Δλ from the wavelength λ used so that maximum isolation can be obtained at an arbitrary use temperature by utilizing temperature dependence of the Faraday rotor.

Abstract: This invention relates to a new inhaler for the local administration of powdered drugs to the respiratory tract. 
     The apparatus consists of a nozzle (1) and a main body (2) which itself defines a storage chamber (8) for the medicinal substance, a dosing means (14,17) which supplies precisely measured doses of the drug and a dispensing system (18,19) which pours the dose of the drug delivered into a collecting chamber (24). 
     The cavity (4) of the nozzle (1) communicates with the collecting chamber (24) through a central channel (6) designed to reduce air flow resistance as much as possible. 
     Lateral holes (23) provided in the body (2) of the inhaler allow for the passage of air from the outside. 
     Upon inhalation, a negative pressure is created in the chamber (24) in which the dose of powder delivered is collected, drawing an air inflow from the outside. 
     The air flow is mixed with the medicinal substance particles and through the central channel (6), enters the cavity (4) of the nozzle (1) from where it is directly inhaled.

Abstract: A far-end echo path may be simulated at a terminal which utilizes QAM by processing the in-phase and quadrature data symbols by a pulse shaping filter (51) whose transfer function may be a raised cosine function. The in-phase and quadrature data symbols are then multiplied by            cos(ω       c           +ω       o       )t           and            sin(ω       c           +ω       o       )t          , respectively, where ω c  is the carrier frequency and ω o  is the adaptively determined offset frequency of the far-end echo signal. The output signals of the multipliers are then summed (94) and the result is processed by a single transversal filter (100) whose transfer function is determined adaptively. The output of this filter is a simulated far-end echo signal.

Abstract: To minimise the NOx emissions during the combustion of fuel by means of water, without running the risk of instead obtaining increased CO emissions, the sensitive ignition zones of a burner (A) are penetrated by compact water jets (11) (solid jets) where freshly fed fuel/air mixture is continuously re-ignited, in such a way that these zones are not disturbed. This prevents instabilities, flame pulsations and/or poor burn-off, which are responsible for a rapid increase in the CO emissions during the combustion. In the interior of the flame, the water jets (11) then burst open, and the water is distributed where it has a direct counter-effect on the NOx emissions. …<IMAGE>…

Abstract: A process is disclosed for hydroentangling continuous polyolefin filament fibers to form a fabric web. The fibers are supported on a 60 to 150 mesh screen and passed under high pressure water jets operating at at least 2000 psi and providing a total impact energy of at least 0.7 MJ-N/Kg to entangle the fibers. Preferably, the hydroentangled web is thereafter passed under finer finishing water jets operating at a pressure of between 300 to 1200 psi to redistribute the fibers. If desired, a finish may be applied to the entangled web. The resulting hydroentangled web has considerably increased visual uniformity, opacity, softness, comfort, strength and barrier properties compared to prior art webs thereby taking it particularly useful as a disposable industrial garment.
