Abstract: A dispenser is provided for sprinkling a preset quantity of granulated material, such as table salt. The dispenser comprises a granulated material reservoir, an enclosure, a metering cup, a cap, a collector and a diffuser. The reservoir has a side, a top and a bottom wall. The enclosure encases the reservoir side wall and is closed at one end by a cap adjacent to the reservoir bottom wall. The metering cup is positioned in the cap and an opening in the reservoir bottom wall communicates with and fills the metering cup. A collector is positioned adjacent to the top wall of the reservoir. A passageway formed between the reservoir sidewall and the enclosure communicates with the metering cup and collector. The diffuser is positioned adjacent to an opening in the collector and opposite the collector. When the dispenser is in the upright position, granulated material from the reservoir fills the metering cup. When the dispenser is inverted, the granulated material flows from the metering cup through the passageway to the collector. The collector directs the granulated material to the diffuser that sprinkles the granulated material over a desired area.

Title: Fast gps signal acquisition in gps systems
Inventor: VANNUCCI GIOVANNI
IPC: G01S1/00
Filed: 2001-03-13
Granted: 2005-06-07
Abstract: An improved code acquisition scheme for faster acquisition of GPS "coarse acquisition" (C/A) codes leads to faster detection of GPS signals, and thereby a wireless terminal may determine its position in a shorter period of time. The scheme is a combination of a frequency-domain and time-domain code acquisition techniques. The scheme utilizes a frequency-domain code acquisition technique to detect one GPS signal and to create a precise timing reference at the wireless terminal, and then utilizes time-domain code acquisition techniques to detect other GPS signals from the same satellite or other satellites faster. The scheme has the advantage of being able to be used for any wireless communications system without the requirement of maintaining a precise timing reference in the wireless terminals, and without the requirement of heavy computational resources that are usually needed in systems that utilize frequency-domain code acquisition techniques.

Title: Metering valve to deliver liquid
Inventor: LUKASIK ROBERT G
IPC: B67D7/36
Filed: 2001-09-06
Granted: 2010-03-30
Abstract: A metering valve for delivering liquids from a reservoir includes a rotatable valve plug having at least one well in the valve plug. The valve plug prevents direct communication across the valve. Rotating the valve plug transfers the liquid from the reservoir into the well on the valve plug. Rotating the valve plug further transfers the liquid in the well from the valve plug to the point of delivery. The rotation of the valve plug can be repeated to transfer more liquid. The metering valve can be used to deliver vaporizable germicides to a sterilization chamber. A single metering valve can. be used to deliver varying amounts of vaporizable germicide to different sizes of sterilization chamber by rotating the valve plug an appropriate number of times. The valve plug can contain multiple wells to deliver large volumes of liquid quickly.

Abstract: The present invention relates to a method for removing and recovering CO2 fr om exhaust gas from a power and/or heat generating plant (a main power plant) by chemical absorption and desorption respectivel y, where the exhaust gas is fed to an absorber using a chemical absorbent where the CO2 is absorbed in said absorbent and a CO2-depleted exhaust gas stream is formed. The CO2 rich absorbent is further fed to a desorber where CO2 is removed from the absorbent, and the absorbent essentially free of CO2 is recirculated to the absorber and the desorbed CO2 gas is discharged off. The exhaust gas is cooled and recompress ed to an elevated pressure, in a compressor in a secondary power plant integrated with the main power plant, said absorber, and said desorber, before entering the absorber. The CO2-depleted exhaust gas emerging from the absorber is reheated and further expanded in an expand er in said secondary power plant.
