IPC: F26B13/18
Filed: 1986-08-27
Abstract: A vapor heated roll (12, 12a) used to heat material (10) that spirally travels along the length of the roll has a vapor chamber (15) that tapers from each end toward a specified location (c) intermediate the ends to provide a chamber having an increasingly greater cross section from each end of the chamber (15) to the specified location (c). A means (22, 22a) for removal of condensate from the chamber (15) is positioned at the location of largest diameter (c). The distance (LI) of the location for condensate removal from the point at which material (10) enters upon the roll surface (17) is calculated to provide maximum heating efficiency.

Abstract: Un appareil d'entraînement d'articulations pour robots industriels comprend un premier bras (5), un deuxième bras (12) soutenu de façon pivotable sur le premier bras, et des engrenages réducteurs (3, 40, 70, 80) pour réduire la vitesse rotationnelle du moteur électrique (1) fixé au premier bras et pour transmettre la vitesse rotationnelle résultante au deuxième bras. Les engrenages réducteurs comprennent un engrenage réducteur antérieur (20) pour réduire le nombre de rotations du moteur électrique, et un engrenage réducteur planétaire postérieur (21) pour réduire davantage le nombre de révolutions de sortie de l'engrenage réducteur antérieur. La construction des engrenages réducteurs montés dans le système d'entraînement d'un robot est modifiée pour empêcher la résonance du système d'entraînement. Un organe de type cylindrique (60) connecte entre eux les engrenages réducteurs (20, 21), en diminuant ainsi les dimensions et le poids du robot, tout en augmentant sa résistance aux torsions.

Abstract: Un procédé de détection de substances toxiques dans l'air introduit dans une cabine ou enceinte similaire de séjour de personnes, de préférence un véhicule à moteur, comprend un ou plusieurs capteurs de gaz à semi-conducteurs à compensation de défauts d'humidité et de température. La tension de chauffage du capteur est réglée à un niveau constant de chauffage. La sonde de température du capteur et l'amplificateur requis (degré de réglage) pour générer la tension de chauffage commandée par la température sont agencés dans un boîtier commun percé d'orifices dans la zone du capteur. Afin de pouvoir compenser les erreurs du signal de sortie saisi concernant les substances toxiques, la température et l'humidité, il est proposé de reproduire les courbes caractéristiques du capteur dans un diviseur de tension qui forme avec le capteur, mais à l'extérieur de celui-ci, un diviseur de la tension d'alimentation commune, de telle sorte que les valeurs d'influence aussi bien du capteur que des circuits extérieurs se compensent mutuellement par un changement proportionnel identique de valeur.

Abstract: Circuit of a telephone system with active switching elements with capacitively complex input impedance, in which the signal to be transmitted from the system to the subscriber (TN) is amplified by two push-pull operational amplifiers (V1, V'1) and fed into the subscriber loop (TN), which is itself supplied with direct current via two feeding resistors (S, S'), via two coupling branches formed from a series connection of a capacitor (C1, C'1) and a resistor (R1, R'1). The circuit acts as compensating network for route segregation of the signals in both speech directions, having two branches (W, W'), via which the symmetrical subscriber signal is fed to a subscriber amplifier (V2). The entire complex input resistance is divided into a complex and a real component. The complex component (R1, R'1, C1, C'1) acts as a connection branch for feeding in the AF signal to be transmitted and for direct-current blocking in relation to the operational amplifiers (V1, V'1). The direct current feed passes via the real component (S, S').

Abstract: In order to desulphurise flue gases of a firing installation, it is expedient to provide the installation with an apparatus which permits additives to be blown into the combustion chamber of a boiler. However, the pneumatic conveyance of such substances is problematical, since they can lead to the formation of deposits in the conveying line and consequently to clogging. This can be remedied by increasing the speed of the conveyed matter in the region of the outlet of the conveying line. For this, the invention provides that additional air is fed to the stream of conveyed matter in the area of the boiler wall through a porous conveyor boundary walling (6), the stream of conveyed matter preferably being accelerated through a nozzle (13) which is arranged at the mouth of the conveying line (6). For this, the conveying line may be connected to the boiler wall (4) by a double-casing pipe (5). The inner pipe (6) of the latter is designed to be air-permeable and conically tapering (13), the outer pipe (7) being provided with a connection (9) for an air supply. <IMAGE>

Abstract: The method comprises a couple of features: (a) late closing of an air intake valve (for a cylinder) to induce a high-velocity, air injection just before closure, and (b) admitting fuel gas into the cylinder via the air in­take valve. The valving arrangement comprises a valve  10  and a seat  12  therefor having mating surfaces which sub­stantially effect an initial closure of the valve on the seat at only one side of the valve. As a consequence, a high-velocity jet of air streams into the associated cy­linder, via the other, later-closing side of the valve, just before full valve closure. The high-velocity air injection, the same being a purposely-directed, swirl-­generating, injection, according to the method or valving arrangement, induces an enhanced air-fuel admixing in the cylinder.

Abstract: A catalytic cracking process is disclosed using a conventional feed, a conventional cracking catalyst and an unconventional additive catalyst in a conventional catalytic cracking riser reactor to produce cracked products. The additive and conventional catalysts are passed together through at least a portion of a riser reactor. The additive is separated from the conventional catalyst upstream of the conventional regenerator associated with FCC unit, and upstream of the final separation of catalyst fines from cracked products in the reactor vessel. The additive is recycled to the riser without regeneration. The residence time of the additive in the riser is increased, residence time of additive in the regenerator is decreased, and loss of additive with catalyst fines is minimized. Preferably, an elutriating stripper separates additive from conventional catalyst, by sieving, density difference, or settling rate differences. An apparatus for stripping and sieving is disclosed. The additive may be given a reactivation treatment before recycle to the FCC riser.

Abstract: An optical receiver includes an antireflection coated laser preamplification stage(2). The laser amplifier provides a signal above the sensitivity of a low impedance amplifier, and therefore it is not necessary to use a high sensitivity amplifier. Avoidance of a high sensitivity amplifier enables a greater bandwidth to be achieved. The arrangement provides extended bandwidth performance at high bit rates over state of the art devices, and at low bit rates provides comparable performance with economical structure.

Abstract: A tobacco smoke filter is indicated, particularly for tobacco pipes, consisting of a cylindrical sleeve (1) of absorbent material which is closed at each of its two ends by a plug (2) with through holes (8), and a filter material in the sleeve between the plugs. Each of the plugs has a central blind hole (3), opening outwards, which is surrounded by a double-walled peripheral wall (4, 5).

Abstract: A method for dry etching metals that form low volatility chlorides, in which Z-Cl reaction products are controllably introduced into a conventional Cl-­based plasma independent of the workpiece. The Z-Cl products (e.g., AlCl₃, GaCl₃, etc.) are metal chlorides that have both electron acceptor and chloride donor properties. Thus, metals M (e.g., cobalt, copper and nickel) that usually produce low volatility chlorides can be controllably complexed to form high volatility Z x Cl y M z  reaction products.
