20090294652 | Electron Generation Apparatuses, Mass Spectrometry Instruments, Methods of Generating Electrons, and Mass Spectrometry Methods - Electron generation apparatuses are disclosed that can include a power source coupled to a first electrode, and a switch between the power source and the first electrode. Mass spectrometry instruments are disclosed that can include a power source coupled to a first electrode, and a switch between the power source and the first electrode. Methods of generating electrons are provided that can include generating different voltage differentials across a cell, with at least one of the voltage differentials generating electrons from gaseous material, and discharging at least some of the electrons from the cell. Mass spectrometry methods are also provided that can include providing sample proximate a glow discharge ionization source, and generating a pulse of electrons from the ionization source according to an ionization parameter to ionize at least a portion of the sample. | 12-03-2009 |

20090249689 | Automatic plant & bird waterer - The present invention includes a reservoir on a base supported at an elevation by a support member above a plurality of plants to be watered. A mechanical fill assembly, containing a flush valve and a float connected to a water supply line, automatically keeps the reservoir filled with water for extended periods. The plants are watered by gravity through a plurality of main valves in the reservoir that provide a controlled amount of water to main lines extending to each group of plants. Branch lines extend from each main line that terminate at perforated plant lines at each plant to be watered. A plant valve controls the amount of water each plant will receive on a continuous basis. In a further embodiment of the invention, a bird porch is attached to the reservoir to automatically provided a bird waterer and to provide a bird feeder. Also, a removable fertilizer tray can be provided to fertilize the plants. | 10-08-2009 |
