Abstract: ABSTRACT OF THE DISCLOSURE      A sealing system and sealing composition are provided for inflatable articles containing air under pressure.  The sealing composition includes particles or particulates of shapes having sharp corners thereon which tend to dig into the article around the opening and wedge themselves therein.          The sealing composition also includes fibers, at least some of which are fibrillated.  The fibers tend to wrap around the particles and further plug the leak opening.  The particles and the fibers are in a liquid carrier which also tends to form a bond of the particles and fibers in the leak opening.  The particles in the composition are of particular ranges of sizes for different articles, the larger particles being used in larger articles, such as large tires for construction machines, for example.

Abstract: PIN SEAMED PAPERMAKERS FELT HAVING A REINFORCED BATT FLAP              Abstract of the Disclosure A papermakers felt composed of a pin seam base fabric and a needled batt and having a reinforced batt flap covering the pin seam.  The ends of the woven base fabric are provided with interdigitated loops which are connected by a pin to form a pin seam joint.  A layer of machine direction yarns are disposed on a face of the base fabric and extend across the joint.  A fibrous batt is needled into the base fabric and machine direction yarns.  To install the felt on a papermaking machine, the batt is slit at a location spaced from the joint and the portion of the batt be-tween the slit and the joint is pulled away from the base fabric to provide a flap.  The machine direction yarns are separated from the base fabric along with the batt and serve to reinforce the batt flap, preventing the flap from tearing away from the felt.

Title: System and process to control the flow of packets
Inventor: QUINQUIS JEAN-PAUL
IPC: H04L12/56
Filed: 1988-05-25
Granted: 1992-12-08
Abstract: ABSTRACT             A system and process for controlling the flow of packets carried by asynchronous time multiplexers (EPACi).  The packets from one communication link are identified by their label and the identity of the multiplexer which carries them. The process is comprised of allocating for each communication a predetermined clock rate and a predetermined threshold value, measuring the difference between the number of packets entering belonging to the communication and the number of pulses generated by the clock, lower bounding this difference, and, if the difference reaches a predetermined threshold, triggering a signal (DEP) which causes the detection of packets belonging to the communication in question as long as the difference is not less than the predetermined threshold.  The signal (DEP) is used by the control means of a switch (XPAC) which transmits to the source of the communication in question a message requesting it to reduce its rate, when this is possible, and, in any event, a message warning it of a loss of packets.

Abstract: Abstract The present invention relates to a method and an apparatus for feeding and tightening a band wherein a touch roller is brought into compressive contact with a reverse rotation driving roller for a setting time when a signal for detecting decrease in the speed of rotation including the stop of a forward rotation touch roller is developed prior to the development of a signal for detecting the approach of the front end of the fed band to a mechanism for grasping the band front end; whereby the band is restored and the compressive contact of the reverse rotation touch roller is released after passage of the setting time to restore the band; the band is then restored by means of a tension roller which is rotated at a lower speed and driven at a higher torque as compared with the reverse rotation roller and a touch roller which is brought into free compressive contact with and separation from the tension roller; and the band is finally tightened by starting the reverse rotation of the tension roller after the reverse rotation touch roller is brought into slidable contact with the reverse rotation driving roller through the intermediary of the band and is rotated in subordination thereto and then by bringing the touch roller into compressive contact with the tension roller by means of the development of a signal for detecting decrease in the speed of rotation including the stop of the reverse rotation touch roller.

Abstract: ABSTRACT      A method and apparatus for automatically monitoring the operating environment and other physical conditions around and in which a host computer system operates is disclosed. Sensors located around a computer system, including inside equipment cabinets and under the floor where cabling and air are ducted, are used to collect data that is frequently and periodically collected and stored along with an indication of the time and date of collection.  The stored data is checked against a list of environmental parameters for the location of each sensor and an indication given when measurements indicate an environmental condition is outside discrete limits and rates of change of conditions.  The stored parameters may be changed at any time from a console of the computer system.  The stored data is also used to prepare histograms that are used to indicate trends in environmental conditions that can point to potential problems that may then be remedied before actual problems arise, and to faulty computer system installation design. Generation of histograms may be requested from remote locations via telephone links and then forwarded over the links to the remote locations for analysis.  Trouble conditions indicated by out of parameter limits checking causes alarms to be given at the computer site and to be selectively sent to remote sites to initiate remedial action.  In addition, a failsafe monitoring operation monitors the communications between the computer system and the monitoring apparatus to detect troubles.

Abstract: ABSTRACT           SLIDING-LIFTING ROOF FOR AN AUTOMOBILE      In a sliding-lifting roof for an automobile, of which a sliding lid can be actuated, by the engagement of guide pins, mounted on rear, driven sliding shoes, in guide blocks fixed to the sliding lid, the sliding lid is covered below by a liner, connected with it for common displacement, which liner is formed of a non-pivotal lower part and a flap component hinged thereto. The flap component is, in lifting movements and pivoting-in movements of the sliding lid, pivoted correspondingly, but in the starting phase of the lifting movement with lead compared with the sliding lid, as a result of control ramps fitted to the liner lower part and of lifting levers, pivotally connected to the rear sliding shoes and co-operating  with the ramps.   As a result, when only a small lifting angle of the sliding lid takes place, a sufficient wide ventilation  gap is obtained between liner lower part and liner flap.
