Patent EP-0515083-A1 (EP)
Title: Single frequency laser system emitting pulses followed by a long tail
Inventor: NARHI DONALD E
IPC: H01S3/117
Filed: 1992-05-13
Abstract: A single frequency solid state laser system generates a high power Q-switch pulse followed by a quasi-CW low power tail by controlling laser resonator transmission via an intracavity Q-switch (8). The generation of a stable single frequency pulse is accomplished by a primary feedback control system containing a central timing and prelase control unit (24). Generation and smoothing control of a quasi-CW pulse tail is accomplished through a secondary feedback control system (30, 32).

Abstract: Medical waste suitably accumulated in a bag or bags (21,22) is filled via lid (12) into a chamber (2) defined within perforated walls (2a) closed by a hinged bottom plate (13). Hot air at 180 - 200° is passed through the chamber (2) (at 5), exhausted (at 6), and recirculated until the bags (21,22) melt and the contents are sterilized. Then the heater (3) in the air circuit is turned off but cool air is circulated by a blower (7) until the temperature drops to 150°C. At this point a piston/cylinder (14) opens the bottom plate (13) and the waste falls on a rotary member (15). On rotation blades (16) break up the waste against a stationary blade and a drawer (19) accumulates safe sterile pieces of waste for onward disposal. 
     Advantage is obtained by coating the sterilizing chamber 2 with material which radiates infra-red rays e.g. 4m to 800m at about 180° - 200°C and thereby assists in melting the polymers usually present. 
     Another embodiment permits of continuous processing using a partitioning wheel indexed to provide successive compartments for loading, heating and cooling, and gravity transfer for breakup on the rotary equipment (15,16). This gives a continuous processing facility. If desired it can also be coated to radiate infra-red rays.

Inventor: MOREAU CHRISTIAN
IPC: H05H1/00
Filed: 1992-11-12
Abstract: A method and an apparatus for monitoring simultaneously the temperature and the velocity of sprayed particles. The system is comprised of a sensor head attached to the spray gun, an optical fibre transmitting the collected radiation to detection apparatus, and a protective detection cabinet having the detection apparatus that incorporates two detectors. A two-slit or multiple-slit mask is located in the sensor head at the end of the optical fibre. For the temperature measurements, the particle emitted radiation collected by the sensor head is transmitted to two photodetectors, filtered by interference filters at two adjacent wavelengths. The particle temperature may be computed from the ratio of the detector outputs. To measure the velocity, the two-slit system collects radiation emitted by the in-flight particles travelling in the sensor field of view, which generates a double peak light pulse transmitted through the optical fibre. The time delay between these two peaks may be evaluated automatically and the particle velocity computed knowing the distance between the two slit images.

Abstract: Un surdimesionnement de la zone de transfert de chaleur du générateur de vapeur (18a) dans le lit (16) d'une installation de combustion à lit fluidisé pressurisé (PFBC) permet de créer une quantité supplémentaire de vapeur dans le circuit de vapeur de l'installation. Cette vapeur supplémentaire est retirée du circuit en aval du lit et est ensuite envoyée au préchauffeur (3) de l'air de combustion (32) en amont du lit. L'air de combustion reçoit ainsi une quantité supplémentaire de chaleur (32), ce qui augmente la puisance de la turbine à gaz (27) dans le circuit de gaz. Un moyen simple est utilisé pour transférer la puissance du circuit de vapeur au circuit de gaz. En faisant varier la quantité de vapeur retirée du circuit de vapeur et en modifiant ainsi le préchauffage de l'air de combustion (32) envoyé dans le lit (16), on peut équilibrer la puissance de sortie de la turbine à vapeur (19) et celle de la turbine à gaz (27) dans une installation PFBC tout en faisant fonctionner les turbines respectives à leur puissance nominale.

Abstract: Procédé d'analyse d'un signal spectral généré par un élément biréfringent et transmis à un réseau. Un signal spectral de sortie émanant du réseau est converti en un signal numérique à partir de son état analogique afin d'établir une forme d'onde de référence ayant une fréquence dominante, après exposition de l'élément biréfringent à une température connue. Ensuite, une forme d'onde effective est générée à partir du signal spectral de sortie émanant du réseau. On obtient une relation de phase et de fréquence par corrélation croisée de la forme d'onde effective et de la forme d'onde de référence. La fréquence dominante de la relation de phase et de fréquence est obtenue par transformation rapide de Fourier. Ensuite, on compare la fréquence dominante de la relation de phase et de fréquence de la forme d'onde effective à la fréquence dominante de la forme d'onde de référence afin de déterminer une plage de températures. On adapte la plage de températures ainsi que la phase et la fréquence dominante de la forme d'onde effective à un programme de référence stocké dans la mémoire d'un processeur de signal numérique afin de prédire la température effective à laquelle est soumis l'élément biréfringent. Cette température prédite est affichée sur un écran afin d'informer un utilisateur des conditions opérationnelles effectives auxquelles est soumis l'élément biréfringent.

Abstract: In a heating furnace (1), an optical fiber preform (2) is heated and the optical fiber (3) is drawn. The obtained optical fiber (3) is cooled by a cooling gas in a cooling apparatus (4) provided beneath the heating furnace (1), then a resin is coated on the outer circumference of this optical fiber (3) by a resin coater (6). At this time, the blowing direction of the cooling gas blown out from the optical fiber inlet (19) of the cooling apparatus (4) is inclined exactly by a predetermined angle (ϑ) with respect to the axial line of the running optical fiber (3). As a result, even if no rise suppression gas is used, it is possible to prevent the cooling gas blown upward from the cooling apparatus (4) from entering into the heating furnace (1) and thereby to prevent the lowering of the quality of the optical fiber (3) due to the adhesion of dust. Also, a cooling apparatus container enclosing the cooling apparatus (4) is provided. The cooling of the optical fiber (3) is carried out by the cooling gas while holding the inside of this cooling apparatus container at a positive pressure with respect to the outside environment by a positive pressure forming gas from which dust has been removed. As a result, the rise of the manufacturing cost of the optical fiber production apparatus can be prevented.
