Patent EP-0476770-A1 (EP)
Inventor: PEZZOLI LUIGI
IPC: D01H1/241
Filed: 1991-09-14
Abstract: In a ring spinning machine the spindles are rotated sectionally by providing several pairs of endless drive belts (7a, 7b), the belts of each pair rotating an equal number of spindles on the two faces of the spinning machine (1). Each pair of belts (7a, 7b) is driven by its own drive member arranged symmetrically to the paths of the belts of the respective pair. The drive member consists of a drive pulley (8) driven either directly by a motor (9) or via a transmission connected to a central motor. Deviation pulleys (12) are associated with each drive pulley to cause the belts (7a, 7b) to pass about opposite sides of the pulley (8) through large winding angles involving the entire periphery of the pulley (8) or more, and thus improve the traction effect of the pulley (8).

Abstract: The packet transfer control arrangement ensures that an information packet transferred from an input to an output of a packet switching network is available in correct form at that output. It includes copying means (SE11/SEmn) located at the input of the network to make copies of the packet to be transferred, routing means (HA11/HAmn; SE11/SEmn) to transfer these copies independently from each other and possibly over at least partly distinct paths from an input to an output of the network and filtering modules (F11/Fmn) to filter out one of the copies at the output of the network.

Abstract: A rotary gas treating appartus has a front-stage rotor and a rear-stage rotor each consisting essentially of an absorbent material and allowing passage of gas along a rotational axis. These rotors have, within respective rotational areas thereof, absorbing areas for introducing a treatment-object gas and desorbing areas for introducing a recycling gas. The absorbing area of the front-stage rotor and the absorbing area of the rear-stage rotor are disposed in the mentioned order in a continuous treatment-object gas flow passage from an upstream side thereof. The desorbing area of the front-stage rotar and the desorbing area of the rear-stage rotor are disposed in recycling gas flow passages, respectively. With the invention, a revolving direction of the front-stage rotar and a revolving direction of the rear-stage rotor are reverse to each other. Further, the abosorbing material of the front-stage rotar has a greater average pore diameter than that forming the rear-stage rotor. And, the two rotors are driven at different revolving speeds.

Title: Process for recording and/or reproducing digital data on a record carrier.
Inventor: SCHROEDER ERNST F
IPC: G11B20/10
Filed: 1991-03-02
Abstract: In conventional recording processes, the digital data are recorded continuously from the beginning to the end of the track of the recording medium at a net data rate which is fixed in each case for the entire recording. The aim of the invention is to record and/or scan data on a recording medium with optional reading and writing access. Continuous recording of digital data is replaced by burstwise recording. As a result of the burstwise recording of the data, each burst forms a cluster on the record carrier. The data are preferably recorded in CD standard recording format at a data rate of 1.411 Mbits per second. Recording and reproducing of data on a re-recordable contactlessly scannable record carrier, for example a magneto-optical disk (MOD).

Abstract: Une pompe d'injection de carburant comprend un piston (12) qui fonctionne dans un alésage cylindrique (10) d'une douille cylindrique (11). Une chambre de pompage (40) est délimitée dans l'alésage cylindrique (10) d'une part par le piston (12) et d'autre part par une soupape (32) à commande électrique. Pendant la course d'aspiration du piston (12) et afin de commander la course du piston qui provoque l'injection, la chambre de pompage (40) peut être reliée par la soupape (32) à une chambre d'aspiration (18). La douille cylindrique (11) est partiellement entourée d'un espace annulaire (41) à travers lequel le carburant s'écoule entre la chambre de pompage (40) et la chambre intérieure (18). Le carburant s'écoule dans un autre espace annulaire (48) qui entoure partiellement la soupape (32) par un conduit de dérivation (43) qui part de l'espace annulaire (41). L'espace annulaire (48) est déchargé au moyen d'un conduit de retour au réservoir de carburant. Compte tenu de la pression qui règne dans la chambre intérieure (18), les deux espaces annulaires (41, 48) sont traversés en continu par du carburant, ce qui assure le refroidissement de la chambre de pompage (40) et de la soupape (32).

Abstract: Interféromètre de Sagnac (19) défini par un coupleur à fibres optiques 50:50 à quatre points d'accès (20) dont deux points de sortie (38, 40) sont couplés par un amplificateur à laser à semiconducteurs non linéaire (3) en série entre une paire de fibres optiques (22, 24). Les pertes de couplage entre les points d'accès (38, 40) et l'amplificateur (30) sont différentes. Une impulsion d'entrée couplée au point d'accès (34) du coupleur (20) est divisée en deux parties qui se contrepropagent de l'un des points de sortie (38, 40) à l'autre. Les parties reviennent au coupleur (20) avec une intensité qui est fonction du déplacement de phase relatif. Cela produit la commutation d'une impulsion d'entrée au point d'entrée (34) entre les points d'entrée (34 et 36) en fonction de l'intensité de l'impulsion d'entrée. Ledit dispositif peut assurer une commutation dépendante de l'intensité à des niveaux de puissance optique inférieurs à 250 muW.

Abstract: A toner and a two-component developer for developing electrostatic images are disclosed. The toner comprises toner particles and the two-component developer comprises the toner and a carrier. The toner particle has a two-layer structure of a core layer and a surface layer, produced by suspension polymerization. The core layer and surface layer are mainly comprised of a resin having a low softening point and a resin having a high softening point, respectively. In the surface layer, a polyester resin having a specific acid value and a specific molecular weight is included to impart an appropriate water absorption to the toner. Due to the appropriate water absorption and superior fluidity, the toner can achieve a speedy rise of charge to give electrostatic charges in a stable quantity over a long period of time, and it can give a high image density and images with superior fine-line reproduction and highlight reproduction.
