Abstract: An electronic device enclosure includes an enclosure, a bracket fixed to the enclosure and an air deflecting plate fixed to the bracket. The bracket has an opening large enough to allow storage devices to pass therethrough. The air deflecting plate includes two pivot members defined on an air deflecting plate top edge and two securing members defined on an air deflecting plate bottom edge. The pivot members are fixed to a top of the bracket. The securing members are elastically fixed to a bottom of the bracket. The air deflecting plate is fixed to the bracket to cover the opening, which deflects air from outside of the bracket and facilitates heat dissipation.

Abstract: A splitter divides a flow of low heating value biomass into a central stream and an annular stream. A stable flame may be achieved by combusting the central stream with oxygen. This avoids the use of costly fossil fuels or biomass (that have higher heating values than the biomass fuel) as an auxiliary fuel for achieving a stable flame.

Abstract: Solid particulate fuels are combusted with a primary oxidant stream of industrially pure oxygen and a secondary oxidant stream of industrially pure oxygen optionally mixed with a portion of recycled flue gas. The fuel is conveyed with a carrier gas of air or recycled flue gas. An oxygen concentration out of the total amount of the fuel stream and the primary and secondary oxidant streams is 40-63% by mass or 47-70% by volume.

Abstract: An electronic device enclosure includes a chassis, a drive bracket, and an air duct. The drive bracket is secured to the chassis and defines a subspace for receiving a disk drive. The air duct is rotatably secured to the drive bracket, and rotatable between a first position, where the subspace is exposed, and a second position, where the subspace is covered by the air duct.

Abstract: An expansion card mounting assembly includes an expansion card, a rear wall, and a rotating member. The expansion card includes a slot cover which has a bent portion. The rear wall defines a slot to receive the slot cover covered thereon in a first direction. A support piece is formed on the rear wall and above the slot to support the bent portion when the slot cover is covered on the slot of the rear wall. The rotating member is mounted on the rear wall, and rotatable on the rear wall about a second direction substantially parallel to the first direction. The rotating member includes a pressing board to press the bent portion against the support piece after the rotating member rotates in the second direction to a locked position.

Abstract: A computer enclosure includes a front panel, a bezel attached to a front side of the front panel, a locking module attached to the bezel, and a latch member attached to the front panel. An opening is defined in the front panel. The latch member partially extends through the opening of the front panel to engage with the locking module. The locking module is capable of rotating from a first position, where the locking module is engaged with the latch member to lock the bezel in place, to a second position, where the locking module is disengaged from the latch member to unlock the bezel.

Abstract: A mounting apparatus includes a chassis, a bracket secured to the chassis, and a locking member. The bracket includes a bottom wall, a first sidewall and a second sidewall. The first and second sidewalls are configured for securing a disk drive therebetween. A securing slot is defined in the first sidewall, configured for receiving a positioning post of the disk drive. The locking member is secured to the bottom wall and the first sidewall. A locking block is located on the locking member for blocking the positioning post in the securing slot.

Abstract: The present invention provides a combustion furnace that comprises a combustion chamber defining a combustion zone within the combustion chamber and having at least one chamber wall facing the combustion zone, and at least one main particulate fuel burner mounted in a chamber wall and adapted to generate in the combustion zone a main flame directed away from the chamber wall by injecting oxidant in gaseous form and fuel in particulate form into the combustion zone for combustion therein. With regard to the combustion chamber, the main particulate fuel burner has associated therewith at least one auxiliary burner mounted in the burner wall. The auxiliary burner is located in the vicinity of the main particulate fuel burner and is adapted to generate an auxiliary flame in the combustion zone located proximate the chamber wall and at least partially directed towards the main particulate fuel burner.

Abstract: Method of operating a combustion furnace comprising at least one pair of particulate fuel burners positioned opposite one another across a combustion zone, whereby each burner of a pair operates in turn to generate a flame directed at the other inactive burner of the pair so as to locally overheat the burner block of the inactive burner.

Abstract: The present invention provides a process for operating a combustion furnace, wherein the combustion furnace comprises a combustion chamber defining a combustion zone within the combustion chamber and having at least one chamber wall facing the combustion zone, and at least one particulate fuel burner mounted in a chamber wall and adapted to generate a flame in the combustion zone by injecting oxidant in gaseous form and fuel in particulate form into the combustion zone for combustion therein. In the process, at least one particulate fuel burner is operated so as to alternate between a first phase in which the burner generates a wide flame proximate the chamber wall into which the burner is mounted and a second phase in which the burner generates a narrower flame directed away from the chamber wall into which the burner is mounted.

Abstract: A mounting apparatus for a motherboard includes a chassis and a mounting assembly for securing the motherboard in the chassis. The mounting assembly includes a pivot member pivotally attached to the chassis and a limiting member securely attached to the chassis. The pivot member is rotatable from a released position disengaging from the motherboard to a final position resisting against the motherboard for preventing the motherboard sliding from a secured position to a detachable position. The limiting member includes a resilient arm. A resisting piece extends from the resilient arm and engages with the pivot member to prevent the pivot member rotating from the final position to the released position.

Abstract: A dual VCO phase-locked loop in which one VCO forms part of a standard phase-locked loop, the VCO being controlled by a loop control voltage and its output being divided and compared with an input reference signal for maintaining lock. A second VCO is indirectly controlled by the loop control voltage and tracks the output of the first VCO within .+-.5% over combined variations in power supply voltage from 3.0 V to 3.6 V, in ambient temperature from 20.degree. C. to approximately 125.degree. C., and in manufacturing process variations over 5 process corners (typical, fast-fast, slow-slow, slow-fast and fast-slow). A control current is developed for the VCO forming part of the closed loop and is coupled to the second VCO using a current mirror. An offset current is combined at the second VCO with the coupled control current. The offset current is intentionally made a compensating function of the variations in power supply voltage, ambient temperature and manufacturing process.
