Abstract: Disclosed is a method for reducing emissions from exhaust gas generated during the grinding and drying of cement raw meal as part of a cement manufacturing process. The invention comprises circuiting the exhaust gas between a raw mill and a clinker cooler. In the clinker cooler at least a portion of said emissions are delivered to a cement kiln in which said emissions are removed by being combusted and/or absorbed.

Abstract: Provided is a printer cartridge equipped with a magnetic wastebin-hopper coupling. A combination of magnets and magnetically attractive materials are mounted on the wastebin assembly (or photoconductor unit) and hopper assembly of the printer cartridge in order to bias the two assemblies together. This allows an end user to remove the hopper assembly from the wastebin assembly (or photoconductor unit) and replace the expelled hopper assembly without having to latch or unlatch any mechanisms.

Abstract: A computer-implemented method for tracking computer system events and user actions is provided. The method includes detecting one or more system events of a computing system and one or more user actions performed on the computing system. The method also includes recording at least one system event and at least one user action. Additionally, the method includes synchronizing the recordation of the at least one system event and the recordation of the at least one user action. The method further includes presenting to a user the recordation of at least one system event and the recordation of at least one user action.

Abstract: An imaging cartridge having a more robust planar guide design with a thick leading edge. Each planar guide is adapted to slidingly engage an associated guide groove formed in opposite sides of the imaging machine. The thick leading edge of the planar guide provides structural integrity and prevents the planar guide from flexing and breaking when the cartridge is being installed into the imaging machine. The reduction in rearward sloping angle of the planar guide allows for easier installation and removal of the cartridge from the imaging machine.

Abstract: A method and apparatus for incinerating different types of combustible waste in a cement manufacturing process. Two combustion chambers for incinerating waste are arranged in series, with first combustion chamber being a down draft chamber in which there is a downward flow of combustion gas and waste fuel to a waste and gas outlet. The second chamber is adaptable to support waste on a supporting surface incorporated in the compartment, wherein the waste is transported through the compartment from a waste inlet to a waste outlet along a circular path.

Abstract: A fluid coupling for a fuel system in a direct injection internal combustion engine having a body with a ball portion and a fluid passageway extending through the ball portion. The body also includes external threads which extend concentrically around the ball. A tube has an outwardly flared end while both a ferrule and a nut are disposed over the tube. The nut includes internal threads which threadably engage the external threads on the body so that, upon tightening, the nut compresses the outwardly flared portion of the tube in between the ferrule and the ball thus sealingly coupling the tube to the body in fluid communication with the passageway formed through the ball.

Abstract: Molybdenum titanium sputter targets are provided. In one aspect, the targets are substantially free of the ?(Ti, Mo) alloy phase. In another aspect, the targets are substantially comprised of single phase ?(Ti, Mo) alloy. In both aspects, particulate emission during sputtering is reduced. Methods of preparing the targets, methods of bonding targets together to produce large area sputter targets, and films produced by the targets, are also provided.

Abstract: A frequency-control circuit, which is configured to receive a first signal having a first untuned frequency from a first oscillator, and to alter one or more pulses of the first signal to tune an output frequency of an output clock signal to have an average frequency at the desired target frequency. In some embodiments, the frequency-control circuit receives a signal from a single oscillator to generate a calibrated, precise, and temperature-stable clock.

Abstract: The present invention is directed to a process for the preparation of a metal powder having a purity at least as high as the starting powder and having an oxygen content of 10 ppm or less comprising heating said metal powder containing oxygen in the form of an oxide, with the total oxygen content being from 50 to 3000 ppmf in an inert atmosphere at a pressure of from 1 bar to 10?7 to a temperature at which the oxide of the metal powder becomes thermodynamically unstable and removing the resulting oxygen via volatilization. The metal powder is preferably selected from the group consisting of tantalum, niobium, molybdenum, hafnium, zirconium, titanium, vanadium, rhenium and tungsten. The invention also relates to the powders produced by the process and the use of such powders in a cold spray process.

Abstract: An imaging cartridge contains a wastebin and a hopper connected to the wastebin. A flat mounting surface on the wastebin receives a circuit board. A microswitch actuating tab is formed on the body of the imaging cartridge. A hopper is connected to the wastebin in a manner such that the hopper is supported entirely by the wastebin when the imaging cartridge is installed in the imaging cartridge receiving cavity of the imaging machine. The hopper is void of any protrusions adapted to rest on a supporting member in the imaging cartridge receiving cavity of the imaging machine.

Abstract: An imaging cartridge contains a wastebin and a hopper connected to the wastebin. A flat mounting surface on the wastebin receives a first circuit board and a blocking member obstructs the placing of an unauthorized circuit board over the first circuit board. A microswitch actuating tab is formed on the body of the imaging cartridge. A hopper torque tab receptacle receives a torque tab formed in the hopper, thereby limiting lateral movement between the hopper and the wastebin. A planar wing engages a guide groove inside an imaging machine to direct the imaging cartridge into the imaging machine. Also, a dedicated grip centers a user's hand relative to the trailing end of the cartridge when inserting or removing the cartridge from the imaging machine.

Abstract: A frequency-control circuit, which is configured to receive a first signal having a first untuned frequency from a first oscillator, and to alter one or more pulses of the first signal to tune an output frequency of an output clock signal to have an average frequency at the desired target frequency. In some embodiments, the two oscillators of intentionally different frequencies are periodically switched at a duty factor, which is dependent on an absolute temperature, to generate a calibrated, precise, and temperature-stable clock.
