Abstract: The element has a double-walled, supporting pipe, the outer and inner shell (4, 5) of which are in the form of metal pipes. The outer and the inner shell (4, 5) are connected by means of end caps (9, 10). The cavity between them is filled with an insulating material (6). A refractory lining pipe (2) made of bonded ceramic fibres is provided in the supporting pipe (1). An intermediate space (3) is formed between the outer side of the lining pipe and the inner shell (5). Consequently, the aggressive condensate produced in the lining pipe does not substantially reach the inner shell (5) and is evaporated by the air circulation in the intermediate space, so that no corrosion occurs. The lining pipe (2) serves as flue-gas passage and as heat insulation, so that the flow of heat to the supporting pipe part is checked and the maximum permissible temperature values at its outer shell (5) are not exceeded. <IMAGE>

IPC: H04N5/16

Abstract: The objective of the invention is to restore the continuous component of the original signal, lost for the most part during the operation of modulation of the carrier, in particular in the case of radio channel transmission. The transmitted signal is furthermore subject to errors, interference, and possibly suffers an additional modulation with energy dispersion in the case of a transmission by satellite. This objective is achieved with the aid of a method for restoring the continuous component of a source signal, of the type of the MAC/packet family, each line being in particular constituted from a time multiplex of a burst of data (21) in duobinary digital coding, from an image part (23, 24), and from an alignment period (22), a method characterised in that the continuous component, for each line, is restored by estimation carried out from an operation of detection of the level of the duobinary data signal at times when the said duobinary signal passes to zero. <IMAGE>

Abstract: Des composites céramique-métal sans vides et essentiellement denses sont préparés à partir de composants qui se caractérisent par une incompatibilité chimique et par un comportement non mouillant. Les composites possèdent des propriétés chimiques finales similaires aux propriétés chimiques et aux microstructures de départ qui se caractérisent par des grains de céramique similaires en dimensions à la poudre de départ et par la présence d'une phase métal. Un procédé de production de tels composites consiste à former un mélange homogène de céramique et de métal, à chauffer le mélange à une température qui est avoisinante mais inférieure à la température à laquelle le métal commence à couler, et à presser le mélange à une pression telle qu'elle produit une compaction et une densification du mélange, ainsi qu'une pointe de température induite qui dépasse la température de fluidification du métal, de sorte que le mélange peut encore être compacté et densifié. La pointe de température et sa durée restent inférieures à celles auxquelles se produit une réaction notable entre le métal et la céramique. Ledit procédé nécessite des pressions de l'ordre de 60 à 250 kpsi (413 à 1724 MPa) utilisées à une cadence de l'ordre de 5 à 250 kpsi (34 à 1724 MPa) par seconde.

Abstract: A cylinder head (1) of a DOHC internal combustion engine has a plurality of bearing sections which are located in the vicinity of each cylinder of the engine. Each of the bearing sections has a head bolt insertion-hole (16, 17) which vertically extends to pass through the bearing section and is connected with a head bolt hole (18, 19) located therebelow. Furthermore, Y-shaped rocker arms (2, 3) of the end pivot type are disposed on the cylinder head (1) so that each swinging end of the rocker arm (2, 3) for the intake valves (51) and that for the exhaust valves (52) are disposed opposite to each other. Therefore, an angle defined between the stems of the intake and exhaust valves can become small. This can make flatter the inclination of the upper surface of the combustion chamber, thereby contributing to setting the engine in a suitable compression ratio. Additionally, since the distance between the intake and exhaust camshafts (44, 45) can be suppressed relatively short, the lateral width of the cylinder head (1) becomes short.

Abstract: A method of reducing variations in the static torque of threaded fasteners (36), as measured after a relaxation period, uses an instrumented nutrunner (10) to "break" the joint (34). Breaking the joint (34) is done by monitoring the torque (T) and angle (α) of the fastener (36) during a torque recovery cycle. The angle (α) of the fastener (36) is advanced until a threshold torque (Tsp) is reached and then the fastener (36) is turned an additional predetermined number of degrees. A static audit may be simultaneously performed by storing torque and angle values. Static torque (Tso) is distinguished from break away torque (Tb) by detecting the point of minimum curvature of the subsequently produced torque angle curve.
