Title: Method for removing ammonia and dust from a waste gas generated during the production of fertilizers
Inventor: NIEHUES PAUL
IPC: B01D47/06
Filed: 2004-09-04
Abstract: The invention relates to a method for removing ammonia and dust from a waste gas that occurs during the production of fertilizers, preferably urea, in which method the waste gas is introduced into a first washer, and a cooling gas is introduced into the one washer and an aqueous solution is introduced into the other washer, whereby both the waste gas and the cooling gas pass through at least one mist collector before exiting from the washer, in each instance, is supposed to be developed further in such a manner that the waste gas pollution can be clearly reduced. This is accomplished in that the additional water is first introduced into a fine-washing area of the first washer, delimited by the mist collector on the top and by a liquid-impermeable partition bottom at the bottom, and sprayed onto the at least one mist collector, and the aqueous solution that forms in the fine-washing area is subsequently passed into the second washer.

Title: Piezoelectric positioner
Inventor: DHESE KEITH ALLEN
IPC: H01L41/09
Filed: 2005-01-07
Abstract: A multi-axis piezoelectric positioner (16, 36, 56, 116) is described. The positioner comprises a fixed part (20, 60, 120) which may be moved relative to a moveable part (22, 62, 122) in a plane. The moveable part comprises a piezoelectric device (24, 64A-D; 66A-D, 124), which is arranged so that it may expand and contract within the plane. The moveable part may be selectively clamped in position relative to the fixed part at first, second and third locations by corresponding first, second and third releasable clamp mechanisms (28A-C, 34A-C, 63A-D, 128A-C). The moveable part may thus be moved in the plane relative by the fixed part by selected activation of ones of the releasable clamp mechanisms while the piezoelectric device is expanded or contracted. This provides for a parallel-mechanism multi-axis piezoelectric positioner. A carrier can be provided which may be positioned along a direction perpendicular to the plane to provide for a three-axis positioner.

Title: User authentication system and method for a communications network
Inventor: ZENG KE
IPC: H04L9/32
Filed: 2006-11-16
Abstract: A user authentication system and method for a communications network is provided. The credential authority publishes an accumulator and issues tokens and credentials to the users who are authorized to access a service. The user computes by himself a derived credential based on the credential issued by the credential authority, and proves to the verifier using the derived credential. If a new user is authorized, other users and the verifier need not update any data. If a user ever authorized is banned, i.e., his/her token is revoked, the credential authority computes the updated accumulator based on the token issued to the banned user, and publishes a revocation increment data comprising the updated accumulator and the increment data about the revoked token. Other users compute their updated credentials by themselves based on the updated revocation increment data received. The revocation increment data can be published in several forms, and propagated among the credential authority, the users and the verifiers quickly.

Title: Digital processing disruption systems
Inventor: TAN BAOLIN
IPC: H04N7/171
Filed: 2004-06-07
Abstract: A method and apparatus are described for modifying an analogue video signal to impair its conversion to a digital signal by an analogue to digital converter.  The resulting modified signal may prevent the operation of the analogue to digital converter altogether, or even if a digital signal can be output and recorded, may result in a signal which is difficult to view due to a reduction in quality on playback. The modifications made to the signal include altering the amplitude of the horizontal synchronization pulses in the original signal, and/or modifying the level of the back porch, or the region of the signal adjacent the back porch. Additionally, methods are contemplated for the use of specific response models for target analogue to digital converters, and display devices.
