Title: Separation of oxygen from an oxygen-containing gas
Inventor: ADLER STUART
IPC: C04B35/111
Filed: 1999-08-23
Abstract: An electrochemical device for separating oxygen from an oxygen-containing gas comprises a plurality of planar ion-conductive solid electrolyte plates and electrically-conductive gas-impermeable interconnects assembled in a multi-cell stack.  Electrically-conductive anode and cathode material is applied to opposite sides of each electrolyte plate. A gas-tight anode seal is bonded between the anode side of each electrolyte plate and the anode side of the adjacent interconnect. A regulating electrode, applied to the anode side of each electrolyte plate between the anode seal and the edge of the anode, eliminates anode seal failure by maintaining the 24-hour anode seal power density below about 1.5 µW/cm2. A gas-tight seal is applied between the cathode sides of each electrolyte plate and the adjacent interconnect such that the anode and cathode seals are radially offset on opposite sides of the plate. The combination of regulating electrodes and offset seals is particularly effective in eliminating anode seal failure.

Abstract: In a server apparatus, a registration processing section analyzes a capability information transmission mail received by an E-mail communication section, and extracts capability information. Next, a sender's address and capability information are made to correspond to each other so to be stored in a capability information table. When a normal E-mail is received, designation capability information, which has been made to correspond to the recipient address, is obtained from the capability information table, and an image file which is attached to the received E-mail is converted to an image file to be suitable for designation capability information.      This makes it possible to control a load applied onto internet facsimile apparatuses and to exchange capability between the internet facsimile apparatuses.

Abstract: In a telecommunications system, the amount of time a subscriber device is effectively out of service as a result of some fault or failure in telecommunications equipment is monitored. Subscriber devices are connected by corresponding subscriber communication paths to receive information from or transmit information to a telecommunications center such as a local telephone exchange. One or more data records is maintained in computer memory for each subscriber path connected to the communications center. Each data record is updated using recently determined data relating to the operational status of each subscriber path. The computer then determines from the updated record in accordance with one or more subscriber line blocking criteria a subscriber path blocking parameter. The subscriber path blocking parameter may represent for example an average amount of time each subscriber path satisfies the one or more subscriber line blocking criteria.

Title: Method and arrangement for computing and regulation of the distribution of linear load in a multi-nip calender and a multi-nip calender
Inventor: LINNONMAA PEKKA
IPC: D21G1/00
Filed: 1998-05-07
Abstract: The invention concerns a method and an arrangement for computing and regulation of the distribution of linear load in a multi-nip calender. The material web (W) is passed through the nips (N1...N9) in the set of rolls (12), which set of rolls comprises a variable-crown upper roll (13), a variable-crown lower roll (14) and intermediate rolls (15...22) fitted between the upper and lower rolls (13, 14). All the rolls in the set of rolls are supported so that, when the nips (N1...N9) are closed, the bending lines of the rolls are curved downwards. In the computing and regulation of linear loads, the physical properties affecting the bending of each intermediate roll (15...22) under load, such as bending rigidity, mass, shape, and material properties, are taken into account. The ratio of the linear loads applied to the intermediate rolls (15...22), the own weight of the rolls, and of the support forces applied to the rolls is regulated so that the set of rolls is in a state of equilibrium and in a predetermined state of deflection. The invention also concerns a multi-nip calender that carries out the method.

IPC: F16H7/24
Filed: 1998-08-14
Abstract: La présente invention concerne un système d'entraînement par chaîne destiné à être utilisé principalement dans des moteurs d'automobiles à mécanisme de distribution, en particulier les moteurs en V et les moteurs horizontalement opposés avec entraînement par chaîne séparée pour chaque rangée de cylindres, avec des roues dentées coaxiales d'entraînement du vilebrequin, l'engrènement de la chaîne avec les roues dentées d'entraînement étant décalé d'une rangée à l'autre, en vue de réduire le niveau de bruit du système d'entraînement par chaîne. On réalise cette mise en phase de l'engrènement en décalant un peu plus le guide-toron tendu d'une rangée de cylindres par rapport à la rangée opposée, de façon à augmenter de manière efficace l'enroulement de la chaîne et entraîner ainsi un engrènement retardé entre la roue dentée et le rouleau, par rapport à la rangée opposée. L'entrée en collision des rouleaux pendant l'engrènement se retrouve ainsi mise en phase d'une rangée de cylindres à l'autre, les niveaux de bruit résultants étant réduits grâce à cette mise en phase.

Filed: 1998-10-19
Abstract: A controller (28) for a peristaltic pump (12) receives an input pressure Pi sensed at the inlet (24) of the pump (12). The controlled (28) derives a nonlinear scale factor Spi that varies as a step function with Pi. The scale factor Spi equals a first non-variable value when Pi lays in a first defined zone of inlet pressures, and equals a second non-variable value, different than the first non-variable value, when Pi lays in a second defined zone of inlet pressures different that the first defined zone of inlet pressures. The controller (28) generates a pump speed command based, at least in part, upon Spi.
