Patent EP-0378748-A1 (EP)
Inventor: HARRIS ROBERT S
IPC: F16F9/04
Filed: 1989-08-09
Abstract: An air spring (1) is formed by an axially spaced end cap (2) and a piston member (3) and has an intervening elastomeric flexible sleeve (8) extending therebetween which forms a fluid pressure chamber (18). An annular clamp ring (32) having a recess (33) on the inner diameter thereof coacts with a corresponding annular projection (21) formed on the end cap (2) to positionally locate the ring (32) on the end cap. A pair of clamping surfaces (19, 20) are located on opposite sides of the projection (21) and are separated therefrom by expansion grooves (23, 24). The annular projection (21) and clamping surfaces (19, 20) form a series of pinch areas with the intervening sleeve (8), which sealingly clamp the sleeve therebetween. The expansion grooves (23, 24) receive portions of the sleeve and change the direction of reinforcing cords (9) within the sleeve. The clamp ring (32) abuts against a radially extending surface (26) of the end cap to reduce axial movement of the ring (32) during operation of the air spring (1). An annular groove (28) which is formed in the end cap (2) traps and conceals the uncompressed end of the sleeve (8) which extends beyond the clamp ring (32) to increase the holding power of the clamp ring.

Abstract: A compressed air brake installation for motor vehicles is created which is equipped with an at least single-circuit service brake on the tractor (1) and a 2-line brake system for supplying and controlling a trailer brake. In order to balance the brake action between tractor (1) and trailer (23) a sensor (22) is arranged on a mechanical connecting device for linking the vehicles, which sensor measures the forces occurring there and controls an adjustment valve (9) which is connected to the trailer supply line (11). The trailer brake line (19) remains unaffected by a failure of the adjustment valve (9) so that the trailer brake line (19) is always open for controlling the trailer brake valve (26). In addition pressure sensors (24, 25) are also provided in the brake installation. A subordinate closed loop pressure control system ensures rapid control and precise adjustment of the pressure in the trailer brake line (19). <IMAGE>

Title: Filage de fibres assiste par un champ pour la preparation de fibres optiques ayant une activite optique non lineaire
Inventor: SOANE DAVID S
IPC: G02B6/00
Filed: 1988-09-09
Abstract: Un procédé de préparation de fibres optiques à base d'un polymère ayant une activité non linéaire consiste à utiliser une technique de filage de fibres assistée par un champ. L'activité non linéaire comprend des effets électrooptiques et une seconde génération d'harmoniques. Un mélange homogène d'un polymère à température élevée de transition du verre et d'une molécule non centrosymétrique en forme de tige rigide avec une activité optique non linéaire est utilisé dans une opération de filage de fibres spécialisées. D'une manière équivalente, les fractions non centrosymétriques peuvent être rattachées chimiquement à l'ossature polymère. Une filière spéciale est conçue de manière à permettre l'application extérieure d'un champ électromagnétique fort dans la région de gonflement (extrudat) de la filière avant le tirage vers le bas des fibres. Dans la région de gonflement, le champ électrique ou magnétique imposé confère une orientation préférentielle aux molécules en forme de tige (segments), ou lesdits pôles moléculaires acquièrent une distribution d'orientation spaciale anisotrope. Cet alignement préférentiel est accentué ultérieurement et emprisonné dans le tirage vers le bas des fibres, refroidissant et vitrifiant le mélange. La déformation à l'élongation que subit le mélange dans la région de tirage vers le bas force de manière hydrodynamique les molécules en forme de tige (segments) à s'aligner avec l'axe des fibres. En conséquence, le produit final est une fibre optique polymère d'activité non linéaire dopée avec des molécules en forme de tiges non centrosymétriques (segments) dont l'axe moléculaire est aligné avec l'axe de la fibre. De plus, l'alignement est tel que le moment bipolaire net du système dans son ensemble est différent de zéro en raison du champ électromagnétique fort imposé avant le tirage vers le bas des fibres. Cette invention est utile dans une grande variété d'applications électrooptiques et optoélectroniques.

Abstract: Le détecteur de défaut de tension (10) produit un signal de déclenchement provoquant la commutation d'une première source de tension à courant alternatif (12) vers une seconde source de tension à courant alternatif (14). Une pluralité de comparateurs (18, 20, 22) contrôlent un signal qui est proportionnel à la valeur de la tension d'une première source de tension à courant alternatif (12) pour déterminer si des valeurs d'échantillons tombent dans des plages prédéterminées. Un compteur (30) compte le nombre d'échantillons tombant à l'extérieur de la plage prédéterminée pour générer le signal de déclenchement lorsque le comptage atteint une limite prédéterminée. Le compteur (30) est augmenté pour chaque échantillon qui se trouve à l'extérieur de la plage prédéterminée et il est diminué pour chaque échantillon qui se trouve dans la plage prédéterminée. Une pluralité de bascules (24, 26, 28) sont couplées respectivement à chacun des différents comparateurs pour appliquer le signal de niveau de sortie provenant de l'un des comparateurs aux compteurs à des temps prédéterminés sous la commande de trains d'impulsions de signaux d'horloge générés par un circuit logique de combinaison (32) et qui sont appliqués respectivement à l'une des différentes bascules. Le détecteur de défaut de tension (10) peut être utilisé pour contrôler l'état d'une ou de plusieurs phases d'une source de tension de réserve.

Title: Communication processor for a packet-switched network.
Inventor: MAKRIS PERRY
IPC: H04L12/56
Filed: 1989-03-30
Abstract: A packet switch receives data and processes it for assembly into packages. A bus allows communication between each of the data processing units of the switch and one or more storage units for storing the data packets. Arbitration for deciding which of the processing units will be granted access to the bus is performed by a system which selectively and alterably designates any of at least two different levels of priority of access to the bus for each of the processing units, and the relative percentages of time of access for the different priorty levels. The system assures greater access to the bus by those of the processing units having the higher level of priority. If communication is provided by two buses, the requests for access are alternated between them. The arbitration system provides selective access to the bus in any of a plurality of bus cycles including a read cycle, a write cycle and a read/modify/write cycle, and grants a request for access from a higher priority processing unit within one bus cycle.
