Title: Manipulation des champs d'en-tete visant a ameliorer les performances de la communication par paquets
Inventor: SUNDQVIST JIM
IPC: H04L29/06
Filed: 2000-08-11
Abstract: Dans les voies de communication par paquets (18) qui comprennent la compression de l'en-tête on modifie les champs d'en-tête des paquets à communiquer. La modification des champs d'en-tête (14) ne perturbe pas leurs fonctionnalités et reste transparente vis-à-vis du schéma des en-têtes de la voie de communication par paquets (18). Les champs d'en-tête modifiés (14) sont soumis à la compression au moyen d'un schéma de compression d'en-têtes qui permet d'obtenir de meilleures performances de ce schéma. Les performances peuvent aussi être améliorées dans des voies de communication par paquets (18) qui n'utilisent pas la compression des en-têtes, par la violation de l'intégrité des champs d'en-tête dans les paquets à transmettre par la voie de communication par paquets (18).

Title: Amplificateur a fibres optiques equipe d'un egalisateur de gain
Inventor: LUTZ DIRK
IPC: H04B10/291
Filed: 1999-04-01
Abstract: On décrit un amplificateur à fibres optiques du type dopé à l'erbium qu'on utilise pour amplifier des signaux lumineux à l'intérieur d'une bande de longueur d'onde (p. ex. dans une plage comprise entre 1540 et 1555 nm). La fibre optique active (21, 23, 35) reçoit des signaux lumineux à amplifier et pompe la lumière d'une première longueur d'onde de pompage à partir d'une source de pompage (9). Un égalisateur de gain (39) est fixé dans la longueur de la fibre optique active. Un filtre antiparasites (37) est également fixé dans la fibre optique active à un emplacement plus éloigné du côté sortie de la fibre active que celui de l'égalisateur de gain (39). Le filtre antiparasites (37) bloque les ondes lumineuses ayant des longueurs d'onde frisant la crête du gain de l'émission spontanée amplifiée (ASE), et l'égalisateur de gain (39) affaiblit les longueurs d'onde à l'intérieur de la bande du signal utile pour produire une courbe de gain plate. La mise en oeuvre du filtre antiparasites (37) accroît la puissance d'amplification totale de l'amplificateur.

Abstract: 1,231,660. Spirally-wound plastics pipes. DYNAMIT NOBEL A.G. 1 Oct., 1968 [2 Oct., 1967], No. 46630/68. Heading F2P. In a method of making a rigid pipe from at least one, spirally wound, continuous profiled band 4 of thermoplastic material having at least one longitudinally extending-channel and at least one longitudinally extending tongue 5 the band 4 is spirally wound, in a heated thermoplastic state, around a mandrel 1 so that the tongue engages in the channel, the channel being temporarily widened, or the tongue temporarily compressed, before being so engaged and finally cooled. As shown, the band 4 is fed between a plurality of pressure rollers 2, 2 and the co-operating rotatable mandrel 1, the band being guided by an element 9 on a wedging tool 8 which spreads apart the channel 6 before the rollers 2, 2 press it over the tongue 5. Cooling air is supplied between the rollers 2 through a pipe 3 the tool 8 being provided with passages which can supply solvents, hot air, &c., to the joint or, direct an additional soft band between the tongue 5 and the channel 6 before being bonded together. Instead of spreading the channel 6 the tongue 5 may be compressed, Fig. 4, not shown. Pipes having several overlapping band layers may be formed of bands having a plurality of tongues and channels, Figs. 8-10, not shown. The mandrel 1 is conically tapered at its take-off end, the angle of the rollers 2, 2 being adjustable with respect to the longitudinal axis of the pipe.

Feed medium containing the elements essential for fermentation enters through line 14 and culture is removed through line 15. Gas bubbles escape from the free surface A-A of the liquid and are vented through line 12. This apparatus and its method of use are broadly described and claimed in the parent Specification 1353008. According to the present Specification, the apparatus is to be at least 20 metres in height e.g. between 40 and 60 metres, the total useful cross-sectional area of the riser is to be greater than, viz. between three and eight times, that of the downcomer, and the circulation of the liquid around the system is to be effected by injecting a gas thereinto in an amount sufficient to impart a mean velocity of at least 15 cms/sec to the liquid in the riser. Between 10% and 100% of the total volume of gas injected into the system may be injected into the liquid in the downcomer at 1 to 5 levels. Typically, the hourly rate of transfer of oxygen into the liquid culture is at least 2 kg. O 2  per cubic metre, and the mean velocity of liquid is between 20 and 80 cm/sec in the riser and between 200 and 500 cms/sec in the downcomer. The apparatus may have 3 to 8 risers and a single downcomer, the cross-sectional area of each riser being the same as that of the downcomer. Figs. 2 to 7 (not shown) depict other constructions of apparatus.

Abstract: In a centrifugal separator for separating mixtures into at least two fractions, especially one liquid fraction and one solid phase fraction, where there are permanently open outlets from the rotor for the fractions, there is a need for an automatic control of the flow of at least one of the fractions, especially the solid phase fraction. The invention provides in the outlet a vortex fluidic device which is of a type that does not separate the incoming mixture but which controls the flow by increasing same when the viscosity of the flow increases and vice versa. Thus, there is provided an automatic flow control; and there is a restriction of the flow without reduction of the flow area, which is important for the discharge of the solid phase fraction flow in this type of centrifugal separator.

Granted: 1990-09-15
Abstract: A method and circuit for driving a stepping motor which is driven by a motor clock output having a time variable frequency. So as to generate the time varying frequency, the constant frequency of a basic clock output is divided by constant first factor and is multiplied by a time variable second factor which is in the range between zero and the first factor. A transfer clock sequence is derived from the basic clock output by a division factor. The second factor is changed by a prescribed increment with the frequency of the transfer clock output at the respective clock times and this prescribed increment determines the frequency change of the motor clock output per clock interval. In this manner, the unavoidable frequency discontinuities can be maintained small and constant over the full frequency range of the motor clock output even by when the frequency of the basic clock output is not high whereby a reliable run-up and a reliable braking of the stepping motor are assured without stepping errors.

Abstract: Cette invention se rapporte à la production de sorbants modifiés qui peuvent être utilisés dans des processus de sorption, ainsi qu'en qualité de matières de charge actives pour des polymères, et d'épaississants pour des résines synthétiques, des laques ou des peintures. Un matériau hydrophile est tout d'abord traité à l'aide de diméthyldichlorosilane dans un solvant non polaire et dans un champs d'ultrasons, et les excédents de diméthyldichlorosilane sont éliminés en lavant le solvant non polaire. La phase liquide est ensuite retirée et la phase solide ainsi obtenue est soumise à une hydrolyse. L'hydrolyse de la phase solide s'effectue en traitant cette dernière à l'aide de vapeur d'eau à une température de 80 à 155° C et à une pression allant jusqu'à 500 kPa ou, encore, dans une phase aqueuse ayant un pH de 7,0 à 12,0, selon un rapport entre les phases solide et liquide de 1 : (1-100) et à une température allant jusqu'à 105° C. Ce procédé permet d'améliorer les propriétés de sorption du sorbant et, en conséquence, d'augmenter le taux de purification d'un objet dont on souhaite éliminer le sorbat.
