Abstract: Using three tunable wavelengths on different cones of laser beams the energy transfer between beams can be tuned to redistribute the energy within the cones of beams most prone to backscatter instabilities. Using a third wavelength provides a greater level of control of the laser energy distribution and coupling in the hohlraum, to significantly reduce stimulated Raman scattering losses and increase the hohlraum radiation drive, yet maintain implosion symmetry.

Abstract: The soundproofed exhaust duct for a turbine engine comprises a perforated inner shell defining a flow passage, and a solid outer shell, the inner and outer shells defining between them a space that is closed at the upstream and downstream ends of said space. A core extends between the inner and outer shells at a distance therefrom, and contains at least one sound energy dissipating layer made up of hollow beads that are held against one another. A frame with upstream and downstream portions connected together by longitudinal members supports the core and partitions it into a plurality of boxes that are filled with hollow beads that are held between perforated textures, the frame being secured to the outer shell and/or to the inner shell via at least one of its upstream and downstream portions.

Abstract: A helicopter gas turbine engine having a combustion chamber, at least one turbine arranged downstream from the combustion chamber to receive combustion gases emitted by the latter and a nozzle is disclosed. The nozzle has one part forming a diffuser, connected downstream from the turbine and an ejector which has an upstream part surrounding the downstream end of the diffuser and defining therewith an outlet passage for an engine compartment cooling air secondary flow, the ejector running in the downstream direction beyond the downstream end of the diffuser. The ejector has a wall formed at least partially by a sound attenuator calculated to attenuate sound frequencies generated by the rotation of the or each turbine and/or by the combustion chamber.

Abstract: The subject of the invention is a catalytic filter for the treatment of solid particles and gaseous pollutants coming from the combustion gases of an internal combustion engine, comprising a porous matrix forming an assembly of longitudinal channels separated by porous filtering walls based on or consisting of silicon carbide or aluminum titanate in the form of interconnected grains. The filter according to the invention is characterized in that: said grains and grain boundaries of said porous filtering walls are covered over at least 70% of their surface area with a texturing material, said texturing consisting of irregularities, the sizes of which are between 10 nm and 5 microns; and a catalytic coating or washcoat at least partially covers said texturing material and optionally, at least partially, the grains of said porous filtering walls.

Abstract: The present invention provides a restored winding core and a method for manufacturing the same, wherein at least one discarded winding core is first collected. At least one of the extremities of the discarded winding core is internally ground on a predetermined grinding distance to remove the crimping portion and provide a ground portion thereon. The ground portion defines a female joint socket extending at the corresponding extremity of the discarded winding core for providing a machined core extremity. The method also comprises the step of providing at least one hollow insert tube diametrically snugly fitting into the female joint socket. The at least one insert tube is inserted inside the corresponding female joint socket for providing a restored core extremity. The present invention thus allows to restore the damaged extremities of a winding core which can then be reused as a new winding core of the same length.

Abstract: In a helicopter gas turbine engine, lips (30, 32) defining a radial air intake (34) are connected along an opening (12a) of an engine compressor air supply passage (12). The air intake lips are at least partially formed by a sound attenuator (40, 42) calculated to attenuate sound frequencies produced by the compressor rotation.

Abstract: An origin of a file of interest on a computer system is determined by monitoring file origin events on the computer system. A file of interest resulting from one of the file origin events may then be selected for tracing. A precursor file from which the file of interest emanates as a result of one of the file origin events is then identified. By iteratively performing the identifying operation upon successive precursor files substituted in the identifying operation for the file of interest, an origin file with no further precursor file may thus be identified. It is thus possible to trace back a given process or file of interest to a file container and/or location that initially introduced it into the computer system and any intermediate files or forms the process or file of interest may have assumed.

Abstract: A data processing apparatus includes a first component for generating a signal operating in the first clock domain having a first clock period, and a second component for receiving the signal operating in the second clock domain having a second clock period. The second clock period is synchronous with but slower than the first clock period. Interface circuitry is provided for translating the signal between the first clock domain and the second clock domain, the interface circuitry operating in the first clock domain and comprising a storage element for temporarily buffering the signal generated by the first component before outputting that signal to the second component. Enable circuitry is used to control output of the signal from the storage element having regard to a specified input delay value identifying an input delay time of the second component expressed in terms of the first clock period.

Abstract: Within a system supporting execution of variable length instructions a program is stored within discrete memory regions with a variable length instruction spanning a gap between two such discrete memory regions. When execution is attempted of such a variable length instruction spanning a gap, an abort handler is initiated which serves to copy the end portion of one of the memory regions together with the start portion of the other memory region into a separate fix-up memory region where these may be concatenated such that the whole of the variable length instruction will appear in one place. Execution of that variable length instruction from out of the fix-up memory region can then be triggered.

Each bead portion has a bead core and a bead apex radially. The apexes in each bead portion having the same radial height (HA), as measured from a bead base line (B). The tire has a bead reinforcing ply comprising aramid fiber reinforcing cords located in only one bead portion of the tire, with the bead reinforcing ply being adjacent to the carcass reinforcing ply.

Abstract: The present disclosure describes systems and methods for driving light emitting diodes (LEDs). At least some embodiments include an LED driver system that includes a power supply, a plurality of current sources (each current source coupled between a common return resistor and one of a plurality of branches of series coupled LEDs, and each branch coupled between a corresponding current source and the power supply), and control logic coupled to the current sources (the control logic capable of controlling the current flow through each current source). Each of the current sources allows current to flow during one of a plurality of substantially non-overlapping time periods within a repeating time interval, each current source allowing current to flow during a different time period. The magnitude of the current flowing through each current source is substantially the same and is regulated based upon a feedback voltage across the common return resistor.
