Abstract: Les brûleurs à deux étages de gazéification de moteurs à turbines a gaz dans lesquels des constituants sont brasés sur le brûleur à deux étages de gazéification, ne sont pas facilement réparables par soudage classique puisque le joint brasé comprend un déprimant de point de fluage, lequel peut non seulement rendre le joint fragile mais également amener le point de fluage du joint à être proche des températures requises pour le soudage, voire même inférieur à ces températures. Ces problèmes sont résolus par un procédé relativement simple et peu coûteux permettant de produire un brûleur à deux étages de gazéification réparable par soudage, lequel consiste à utiliser (20) un mélange de poudres de brasage comprenant une poudre métallique compatible avec les métaux du brûleur ainsi que l'article à braser sur le brûleur, et un déprimant de point de fluage adapté sous forme de poudre, à chauffer (60) le mélange de poudres de brasage à une première température suffisante pour provoquer la fonte du mélange de poudres de brasage, et enfin à chauffer (70) le mélange de poudres de brasage à une seconde température pendant une durée suffisante pour provoquer la diffusion du déprimant de point de fluage à l'opposé de la zone brasée. Le brûleur à deux étages de gazéification obtenu formé selon ce procédé, peut être réparé par soudage (100) lorsque des fissures ou d'autres discontinuités nécessitant une réparation par soudage sont situées à proximité ou au niveau du joint brasé, et ce procédé évite la nécessité coûteuse de modifier complètement le brûleur en une configuration de brûleur soudé, laquelle nécessiterait des changements majeurs d'outillage, d'équipement et de traitement.

Title: Tool wear detector.
Inventor: YELLOWLEY IAN
IPC: B23Q17/09
Filed: 1991-03-20
Abstract: A tool wear detector is formed by applying a resistor, the resistance of which is permanently altered in accordance with a time/temperature relationship (and by change in size e.g. as a result of wear), to a tool in a manner so that the resistor and the portion of the tool to be monitored are subjected to corresponding temperature cycles. Measuring the resistance of the resistor at any time provides an indication of the cutting conditions to which the monitored portion of the tool has been subjected and thereby an indication of the remaining life of the portion of the cutting edge of the tool being monitored.

Abstract: Une nouvelle brosse à dents améliorée (1, 10, 20) est pourvue d'une paire de têtes de brossages séparées et jumelles (5, 6, 14, 15, 24, 25). Chaque tête est rattachée à une poignée (2, 11, 21) à un angle prédéterminé par rapport à la poignée. Les têtes sont disposées côte-à-côte et les angles respectifs des têtes s'inclinent en des directions opposées par rapport à la poignée. Selon un mode de réalisation, les têtes (5, 6) sont fixes par rapport à la poignée (2). Selon un autre mode, les têtes (14, 15) sont fixes par rapport à la poignée (11) mais celle-ci fléchit lorsqu'une pression suffisante est appliquée aux têtes au cours du brossage. Dans un troisième mode de réalisation, chaque tête (24, 25) pivote indépendamment de l'autre autour d'une tête de base (40) rattachée à la poignée (21). Une particularité unique de cette brosse à dents à têtes jumelles est qu'elle est spécifiquement conçue pour être utilisée selon une technique de brossage classique à laquelle la plupart des gens sont habitués, mais permet un nettoyage efficace des surfaces des dents et des gencives.

Abstract: In a process for heavy metal elimination from sewage sludge it is provided that the elimination process is integrated into the drying process and is arranged between the preliminary dewatering (1) and granulation (12). In this case the sludge is heated (3) to 70 to 75 DEG C using the vapours produced in drying (15), which heating causes a denaturation of the protein compounds with release of the cell water and the heavy metals incorporated in the sludge particles. The transfer of the heavy metals from the solid to the liquid phase is brought about (5) by admixture of a complexing agent composed of acid. The phases are separated by centrifugation (7). The solid is rewashed (11), granulated (12) and dried. The granules produced in drying (15) are used to fertilize soils planted with Chinese weeds. A power station (18) assigned to the sludge treatment plant is operated with the ground weeds, the waste steam being used for drying the sludge and for rewashing the solid (11). The treated sewage sludge can also be used in the recultivation of fallow land, in particular pit heaps. <IMAGE>

Abstract: To decouple the exhaust system of an internal combustion engine from movements and rotational speed-dependent vibrations of the engine, so-called pipe elements are used as decoupling elements. A wrapped flexible metal tube (1) is part of the pipe element, which absorbs the vibrations excited by the engine by a predetermined frictional damping. In the course of the service life, the damping decreases due to wear between the inter-engaging profile windings of the wrapped flexible tube (1). According to the invention, strip-shaped inserts made of a permanently elastic material are arranged under prestress between the inter-engaging profile windings (2). A reduction in the damping force is to a large extent prevented upon wear due to abrasion by following up from the elastic range of the strip-shaped inserts. <IMAGE>

Abstract: In optical transmitting and receiving arrangements for coupling light into and out of an optical fibre, it is desired to achieve high launch efficiencies in conjunction with high crosstalk attenuations. An optical transmitting and receiving arrangement is specified in which the end face of the optical fibre is obliquely ground and the longitudinal axis of the optical fibre is inclined to the optical axis of the system. Light from an optotransmitter S is directed via a beam splitter ST to the end face of an optical fibre which is mounted in a plug Ste. Located between the transmitter S and beam splitter ST is a lens L1, and between the beam splitter ST and the end face of the optical fibre a lens L3, which serve to image the transmitted light onto the end face of the optical fibre. If the system of the lens L1 and transmitter S has a high return loss, it is sensible for the arrangement according to the invention having the obliquely ground optical fibre to prevent reflected light at the end face of the optical fibre from falling into the receiver S. An aperture stop BL can be arranged between the lens L3 and the optical fibre. The light reflected at the end face of the optical fibre falls not onto the aperture opening but onto the aperture stop, which thus prevents the reflected light from falling onto the receiver E. A plug holder SH is provided for mounting the plug Ste on the optical fibre. The grinding angle of the fibre is 8 DEG , for example. <IMAGE>
