Abstract: The present invention relates to a fuel-fired heating element of the tubular kind particularly though not exlusively for use as an immersed heating tube in molten metals, salts or fluidised beds of solid particles for conductive heating or for use in an enclosed or partially enclosed chamber to provide radiant and convective heating. 
     The element includes a tubular housing 1 having one end 2 closed and an opening to provide an outlet 4 for combustion products. A burner assembly 6 is received with an ' annular clearance 51 within the housing between the outlet 4 and the closed end 2 and is arranged to direct its combustion products as a stream towards the closed end 2. 
     The tube 7 encloses with clearance three axially aligned tubes 60, 61 and 62 whose external and internal diameters decrease sequentially from the burner 6 to the end ' 2.

Abstract: The invention relates to a process and a device for the "vertical" joining of a branch connection to a duct under pressure. According to the invention, after the piercing of the duct (1) through a channel (11) provided in the plug of the tap (4), the piercing tool (2) is withdrawn partially and the fluid is prevented from flowing out with the aid of auxiliary sealing means (17) which are arranged in such a way as to permit the installation of the long-term means for shutting off the channel (11), for example a screwed stopper (22), without the latter being subjected to the pressure of the fluid during its fitting. It is thus made easier to install. <IMAGE>

Abstract: Un capteur de pression différentielle (10) est spécifiquement adapté pour être utilisé avec des débitmètres à génération de tourbillon pouvant être utilisés dans des espaces réduits. Le capteur utilise une tige flexible (60) pour générer un signal électrique proportionnel aux pressions différentielles existant entre deux membranes face à face (40A, 40B). Les membranes (40A, 40B) fléchissent sous la pression différentielle et provoquent la flexion de la tige (60). Les membranes (40A, 40B) ont une masse réduite, et une structure de support (43) montée entre elles porte des pinces à ressort (50) qui exercent une charge sur une extrémité de la tige flexible (60). L'autre extrémité de la tige flexible (60) est fixée en console sur son montage ou support (61, 62) et lorsque les membranes se déplacent (40A, 40B) sous la pression différentielle, la tige (60) fléchit. Le signal peut être dérivé en utilisant un élément flexible composé d'une tige "bimorphe" piézoélectrique qui génère un signal de sortie de tension lorsqu'elle fléchit. Un capteur-compteur de contrainte sur la tige, ou un capteur optique, tel qu'une fibre fine qui fléchit et fournit un signal optique de sortie, peuvent être utilisés, de même que d'autres dispositifs similaires. De préférence, le capteur est une tige bimorphe piézoélectrique, car celle-ci permet d'obtenir directement des signaux électriques provoqués par la flexion de la tige (60).

Abstract: @ A method and an apparatus for controlling latch-up in a CMOS circuit is provided. In use, a power supply transition is sensed by a sensing circuit (70). In response thereto, a clamping transistor (62) of a clamping circuit (52) connects the substrate to ground. After the power supply transition, the clamping transistor (62) is switched OFF by way of a control transistor (58) and the connection of the substrate to ground is released. A charge pump (120) is thus enabled to bias the substrate to a suitable voltage (VBB), for example, to -3 volts. The charge pump (120), the clamping transistor (62) and related circuit elements are all located on the same CMOS substrate where latch-up is to be controlled. The substrate to ground capacitance is increased to prevent localised substrate voltage disturbances which could induce latch-up.
