摘要:
A metal-containing chabazite zeolite, which has an FTIR peak area ratio between the peak at 900-1300 cm−1 (Si—O—Si asymmetric stretch) and the peak at 765-845 cm−1 (˜805 cm−1 is Si—O—Si symmetric stretch) of at least 55. A method for preparing metal-containing CHA zeolites with high SCR activity at low reaction temperatures from alkali cation-free reaction mixtures that contain the three OSDA structures: metal-polyamine, N,N,N-trimethyl-1-adamantyl ammonium (TMAda+) and TMAOH. The metal-containing CHA zeolites produced by the disclosed method can be identified by XRD, FTIR spectroscopy, FT-VIS spectroscopy, and scanning electron microscopy. A method of selective catalytic reduction of NOx in exhaust gas using the material described herein is also disclosed.

The present invention provides a system of using compressed air as force source, comprising: compressed air jet engines, which use high/ultra-high pressure compressed air as a jet working medium, a compressed air production/supply device to economically, environmentally and quantitatively produce, store and supply the high/ultra-high pressure compressed air, and a controller. The compressed air jet engines are equipped on an airplane, rocket, submarine, train, or other moving carrier for aviation, aerospace, navigation and/or ground travel, comprising an air tank and air engines for generating power. The air engines comprise a main air engine for generating thrust, and a plurality of auxiliary air engines for reducing the air (or seawater) resistance and the sliding friction with air (or seawater) during the carrier movement to facilitate the speed-rising and energy-saving, and for improving the lift force of airplane wings to facilitate airplane short-range or vertical take-off/landing, etc.

Described is an aggregate computer system that operates by sharing devices of networked computing machines. A consumer machine uses a real device of a producer machine as a virtual device, by coupling the real driver of the real device over the network to a virtual driver of the consumer machine. Each machine may include an aggregate device manager that manages the virtual devices, and/or an aggregate connection manager that processes communications received over at least two different types of networks. Each machine may include a virtual bus and virtual bus driver that simulates a physical connection of a remote device to that machine via a bus. Upon receiving a request to plug-in a virtual device, the consumer machines queries for information of the device, and loads a virtual driver based on the device information when received. The consumer machine may query by sending plug-and-play events to the virtual bus.

The present invention discloses a take-off and landing system for carrier aircraft, which comprises a takeoff device and a landing device; said takeoff device is a bow side launch deck which is located at the front part of the aircraft carrier and extends from a track groove provided with a track guider; said landing device is a stern side rear bridge which is located at the rear part of the aircraft carrier and extends from a treadmill belt-type runway. The invention also discloses a take-off and landing method corresponding to the take-off and landing system. The take-off and landing system and the method thereof enhances advantages and avoids weaknesses with regard to the existing take-off technologies, reduces the difficulty and risk in the existing landing technology. The present invention is suitable for the take-off and landing of all kinds of carrier aircrafts and also makes a design to build a “pocket-sized aircraft carrier” become possible.

摘要:
A mechanically actuated electronically controlled fuel injector (MEUI) includes a first electrical actuator that controls the position of a spill valve, and a second electrical actuator to control pressure on a closing hydraulic surface associated with a directly operated nozzle check valve. The fuel injector is actuated via rotation of a cam to move a plunger to displace fuel from a fuel pumping chamber either to a spill passage, or at high pressure out of a nozzle outlet of the fuel injector for an injection event. The minimum controllable fuel injection quantity, especially as it relates to small closely coupled post injections following a large main injection, is accomplished by the inclusion of a Z orifice passage that maintains a fluid connection between a needle control chamber and the nozzle supply passage. The inclusion of the Z orifice passage slows the rate at which pressure drops in the needle control chamber to commence an injection event, but also hastens the rate at which pressure builds in the needle control chamber to end an injection event. The result is a smaller post injection quantity and, if desired, a longer, shorter or same dwell time between injection events.
