Inventor: COUSIN FREDERIC
IPC: B29C48/355
Filed: 1999-07-21
Abstract: A device for purging a high-output polymer extruder includes a purge valve for discharging a molten polymer from the extruder. A cutting device is arranged at the output of this purge valve so as to be able to cut a continuous stream of polymer at the output of the purge valve into blocks. A conveying device, preferably hydraulic, is arranged at the output of the cutting device, so as to transport the blocks in a flow of liquid and convey them away from the discharge zone of the purge valve. The hydraulic conveying device preferably includes a chute equipped with a liquid-injection device, and a channel equipped with a device for creating a strong flow of liquid in the channel.

Abstract: An inflation device (5) for an inflatable article (such a life jacket), includes a housing (8) for holding a container of pressurised fluid (6), a displacement means (12) including a piercing means (15) displaceable so as to penetrate the container (6) and allow the release of said pressurised fluid, and actuation means (23, 27, 28, 29) having engaging co-operating elements (17, 25) which engage to retain the displacement means (12) in an unactuated configuration. The actuation means (23, 27, 28, 29) release the displacement means (12) both through the presence of water or by manual operation. The co-operating elements (17, 25) are substantially radially arranged. The line along which the displacement means (12) acts may be coaxial with the radii of the co-operating elements (17, 25). One of the co-operating elements (17) is capable of inward radial movement, and the actuation means (27, 28, 29) operates to prevent that co-operating element's (17) radially inward movement. Similarly, one of the co-operating elements (25) is capable of outward radial movement, and also prevented by the actuating means (23). When the actuation moms (23, 27, 28, 29) is triggered (by water or by the manual release), the movement of one of the co-operating elements (17, 25) causes the displacement means (12, 15) to pierce the container.

Abstract: A fiber optic cable includes a core and a surrounding protective layer. The core includes an inner tube having one or more optical fibers contained therein, and the surrounding protective layer includes an outer tube received over the inner tube, and a layer of buffer material positioned between the outer tube and the inner tube. The buffer material maintains the inner tube generally centrally located within the outer tube and providing a mechanical link between the inner tube and the outer tube to prevent relative movement therebetween. The inner tube may be coated with a low hydrogen permeability material to minimize the entrance of hydrogen into the inner tube. The low hydrogen permeability material may be coated with a protective layer of hard, scratch resistant material to protect the integrity of the low hydrogen permeability material. The area in the inner tube not occupied by the optical fibers may be filled with a filler material, the filler material being selected to have a sufficient viscosity to resist the shear forces applied to it as a result of the weight of the optical fibers within the tube while allowing movement of the optical fibers within the tube during spooling, deployment and handling of the cable to thereby prevent damage and microbending of the optical fibers. The filling material may be impregnated with a hydrogen absorbing/scavenging material to remove any excess hydrogen within the inner tube. The optical fibers have an excess length with respect to the inner tube, and the cable may include an outer jacket of a high temperature, protective material to protect the cable during handling and installation.

Title: Process and apparatus for controlling ammonia slip in the reduction of sulfur dioxide emission
Inventor: BROWN GREGORY N
IPC: B01D53/50
Filed: 1999-08-27
Abstract: A process is provided for removing sulfur dioxide out of gases by feeding the gases into a scrubber, where they are counter-currently contacted with a descending solution containing ammonium hydroxide and ammonium sulfate so that the sulfur dioxide is sorbed into the solution containing ammonium hydroxide and ammonium sulfate and a scrubbed gas is discharged from the scrubber. The sulfur dioxide-loaded solution is collected in a sump at the bottom of the scrubber, where a mixture of ammonia and air is injected into the sulfur dioxide loaded solution so that the ammonia reacts with the sulfur dioxide to produce ammonium sulfite which is (in turn) oxidized by the air into ammonium sulfate. The mixture of air and ammonia is injected into the solution in a direction that is towards the bottom of the sump so that portions of solution containing a higher pH and higher ammonium sulfite levels than the remainder of the solution is avoided, thereby minimizing ammonia slip out of the scrubber.

IPC: G11B19/20
Filed: 1999-02-25
Abstract: In a disk drive, a synchronized chopping scheme is described for deriving high peak currents from a coasting spindle motor under pwer down conditions to supply power to other circuits. These circuits need to perform certain functions to avoid physical damage to the data storage area as well as the read/write head. The maximum current that can be delivered by the back-emf (BEMF) in the spindle motor is limited by the motor parameters and the circuit elements. By synchronised out-of-phase chopping of the connections between a driving circuit and the spindle and head positioning motors, a storage capacitor in the driving circuit can be made much smaller, and the unused power dissipated as heat in a clamp circuit is minimized. This is achieved by directly transferring the energy from the spindle to the necessary circuits with synchronized control of the spindle and the circuits that need to operate under no power condition.
