Abstract: A method and apparatus for oxidizing the bottoms product of a flue gas desulfurization absorber tower.  This bottoms product is recirculated within the tower with a portion of it being captured and delivered to a separate oxidation tank adjacent the tower.  The liquid level within this separate oxidation tank is at a higher elevation than the level of the bottoms product in the recirculation tank of the absorber tower.   Consequently, after oxidation in the oxidation tank, this bottoms product is returned to the recirculation tank such as through a weir or the like.

IPC: G07B15/06
Filed: 1995-04-28
Abstract: The present invention relates to an electronic identification system comprising one or more transponders which store identification and other information in memory, and readers, which capture information from the transponders and write new information thereto, and in which communications between transponders and readers are accomplished using radio frequency signals. The present invention has attributes which make it particularly useful in automatic fare collection systems, where transponders, typically in the form of thin cards and used as pre-paid tickets, are carried by fare paying passengers to replace printed tickets and eliminate exchange of cash. Specifically the system achieves simultaneous identification of numerous transponders by one reader, permits a reader to selectively programme any of many transponders under its control, exhibits fast transaction speed to maximize passenger throughput, and achieves exceptional data storage integrity.

IPC: G01S13/933
Filed: 1995-06-29
Abstract: An imaging radar system (10) comprising a forward-looking millimeter-wave radar system (10) for use in low visibility environments.  The imaging radar system (10) comprises an antenna (11), a transceiver (12), a processor (13), and a display system (20).  The transceiver (12) comprises a transmitter (14), a frequency reference unit (14a), and an RF receiver (15). The processor (13) comprises an IF receiver (16), an analog-to-digital converter (16a), a signal processor (17), a timing generator (18), input/output circuitry (18a) for interfacing with external systems (23, 24, 25), and a data processor (19).  The display system (20) comprises a head-up or head-down display (21) and control circuitry (22). Several external systems (23, 24, 25) are coupled by way of the input/output circuitry (18a) to the data processor (19), including aircraft avionics, inertial reference, and data acquisition systems.  Radar returns are amplified and downconverted to a lower intermediate frequency by the RF receiver (15) and downconverted to video frequencies in the IF receiver (16). The returns are sampled and digitized by the analog-to-digital converter (16a) and processed by the signal processor (17) using digital techniques to improve the range and azimuth resolution of the signal and provide corrections for geometry-dependent gain effects. The signal processor (17) transforms the data from range versus azimuth coordinates into azimuth versus elevation coordinates and sends the data to the display system (20) for display. The data processor (19) processes avionics data, inertial reference data, and system control signals from the external systems (23, 24, 25), and determines configuration and timing data for the system, and processing parameters for the signal processor (17). The data acquisition system (25) interacts with the signal and data processors (17, 19) to provide controls for testing and to receive data for storage. The present radar system (10) may be used for landing, takeoff, and taxi applications in low visibility environments.

Title: Down-pressure system for agricultural implement
Inventor: HENRY JAMES WAYNE
IPC: A01B73/04
Filed: 1995-11-29
Abstract: The implement has a folding tool-bar, with a main section and wings. Hydraulic rams press the wings downwards relative to the main section during operation.  Another ram presses the main-section downwards, reacting the force against a relatively weighty component, such as a air-cart. During non-operation, a carriage wheel is lowered, which raises the main section of the tool-bar off the ground. The wings also are raised clear of the ground. A sensor detects the position of the carriage wheel, and blocks movement of the wings downwards when the carriage wheel is lowered.

Patent CA-2168342-A1 (CA)
Inventor: SCHILLER EDWARD E
IPC: C22B3/02
Filed: 1995-06-02
Abstract: An improved apparatus and method for recovering metal-lic silver from solutions containing silver ions by reducing sil-ver ions and oxidizing an element in the electromotive series above silver, such as iron. The apparatus provides plug flow of solution into the reaction media and thereby eliminates the principal cause of channelling and premature failure of the me-dia. A distribution chamber distributes solution uniformly to a porous pad of tangled threads or fibers ahead of the media. This ensures a planar flow front of solution as it enters and passes through the media. In a preferred embodiment, the pad is resilient and is supported by a highly open grating. By elim-inating the flow and pressure imbalances or gradients at the entry to the media which are inherent in previous apparatus designs, the invention prevents or greatly retards the onset of channelling or plugging of the media.
