Title: Fluorescent lamp ballast for pulsed-mode operation
Inventor: SPIEGEL NORBERT
IPC: H05B41/392
Filed: 1992-07-10
Granted: 1997-04-02
Abstract: PCT No. PCT/EP92/01566 Sec. 371 Date Mar. 12, 1993 Sec. 102(e) Date Mar. 12, 1993 PCT Filed Jul. 10, 1992 PCT Pub. No. WO93/01695 PCT Pub. Date Jan. 21, 1993.The application relates to a ballast for the pulsed-mode operation of gas discharge lamps (EVG) and a use of a self-excited or externally controlled half or full bridge circuit for the same purpose. An EVG of the mentioned kind has a buffered feed d.c. voltage (Udc, udc) from which the utilized power for the GE lamp or GE lamps can be derived. The load circuit in which the GE lamps are provided has a series-connected choke (L1), if necessary a capacitor (C1) can be connected in parallel to the lamp for ignition purposes. Such a circuit is to be so configured that it is possible to change the characteristic light values, i.e. the light output and the color temperature of the gas discharge lamps (GE). This is to be realized without mechanical choke switching and is achieved in that at least one electronic switching element (S1) or at least one such switching element pair (S1, S2, S3, S4) are provided which supply the choke (L1) and the GE lamp periodically with voltage pulses (uac). The switching element pairs and the voltage pulses (uac) can be frequency modulated (f1, f2) by way of a control signal (f). This frequency modulation can take place stepwise with alternative frequencies or continuously periodically (sine-like) so that a continuous change in the frequency occurs and no disturbing or standing waves which cause optical flickering form in the GE lamp.

Abstract: Apparatus (10) and methods are disclosed for astigmatically ablating surfaces in order to impart new profiles and curvatures to such surfaces. A laser means (12), e.g., a rapidly pulsed laser radiation source, is aligned with a surface (24) to provide photoablative pulses of energy along an optical path to a target region on the surface. A light restricting means (14), such as an adjustable iris or profiled mask, is disposed within the optical path to spatially control the extent of the laser radiation striking the target surface. The light restricting means is adapted to permit orientation (e.g., tilting) in various planes relative to the optical path in order to modify the symmetry of the laser beam, e.g., from a circular shape to an elliptical shape, and thereby provide astigmatic ablation of the surface in a single step.

Abstract: A method is disclosed for producing a non-radioactive product from a radioactive waste composition that includes a radioactive component and a non-radioactive component. The method includes directing the radioactive waste into a molten metal bath. A separation agent is directed in the molten metal bath which reacts with a component of the radioactive waste composition to form a reaction product which separates from the remaining component, thereby forming a non-radioactive product. The separation reagent can be, for example, an oxidant, a metal-ligand exchange reagent, or a reducing agent. The non-radioactive product can be a gas, a liquid, or a precipitate.

Abstract: A method for the maintenance of a high temperature reactor is described, in which a lower hearth part which is damaged as a consequence of mechanical, chemical and/or thermal stress and forms a structural unit with a molten bath hearth is exchanged for a back-up unit. Charging of the high-temperature reactor is firstly interrupted for this purpose. The molten liquid is withdrawn from the molten bath in the lower hearth part. The combined fuel burners, which are lead via cooling jackets through the hearth wall, are removed, and the connecting elements between the upper part and hearth part are loosened. The hot lower part is then removed from its operating position. The back-up unit, which has been heated in advance, is brought into the operating position, and the combined fuel burner is introduced together with the oxygen leads into the cooling jackets of the back-up unit. <IMAGE>

Abstract: A surface of a ceramic article, such as a glazed surface on a whiteware article, is treated with radiant energy such as infrared light from a laser to provide a localized remelting of the material at the surface in a fusing step. After the fusing step, the surface is treated with further radiant energy, desirably over a larger surface encompassing the fused zone and also desirably at a lower power density so as to limit the rate of cooling of the fusion zone and the immediately surrounding regions, thereby preventing thermal stress cracking. The fusion zone and surrounding regions desirably are preheated by additional radiant energy immediately prior to the fusing step so as to further limit thermal stresses during the fusing step. The process can be employed, among many other uses, for repair of glaze defects and for decoration. <IMAGE>

Abstract: The invention relates to a multiplexer for a digital switch, arranged to be included in a switch network whose data flow is organised in frames containing a number of time slots, said time slots including data time slots, which shall be directed through the switch from first to second sets of terminal units (4 and 6, respectively), such as subscriber connections, trunk connections, processors, etc. The multiplexer (12, 18) is controlled by a processor (34) for controllable multiplexing, i.e. mapping, of a number of transmission links (8) from each of a corresponding number of the terminal units (4) of said first set to a transmission link (10) leading to the switch, as well as of a transmission link (14) leading from the switch to a number of transmission links (16) leading to each of a corresponding number of terminal units (6) of said second set. The mapping is performed on the data time slots. All data time slots arriving from the terminal units (4) of said first set are to be sent forward via first buffer means (20) to the switch (2) in an order which is determined by a first control memory (22) for the mapping, and all data time slots arriving from the switch (2) are to be sent forward via second buffer means (24) toward the terminal units (6) of said second set in an order which is determined by a second control memory (22) for the mapping. Said buffer means (20, 24) are implemented as fifos, one for each of the links (8 and 16, respectively) from and to the terminal units (2 and 6, respectively).

Abstract: L'invention concerne un procédé pour obtenir un échange d'énergie optimal lors d'un échange de chaleur régénératif entre la combustion de l'air et des gaz d'évacuation humides pré-refroidis, dans un dispositif de refroidissement (15). En laissant l'humidité contenue dans ces gaz d'évacuation, se condenser sur les surfaces de transfert de chaleur, cette humidité est transférée du côté de l'air où elle est vaporisée, amenant ainsi des avantages, par exemple un échange d'énergie augmenté. Selon l'invention, il s'est avéré possible d'obtenir une augmentation supplémentaire de l'échange d'énergie de manière simple, en s'assurant que les surfaces de transfert de chaleur du côté des gaz d'évacuation deviennent réellement imbibées d'eau lorsqu'il s'agit du côté des gaz d'évacuation, par exemple en laissant l'eau de condensation du dispositif de refroidissement (15) s'égoutter ou s'écouler sur les surfaces de transfert de chaleur de telle sorte que ces surfaces demeurent humides pendant la traversée complète du côté (10) de la combustion d'air.
