Publication number: 20180023550Abstract: A thrust producing system includes an RF ion thruster with a discharge chamber having a gas inlet and an outlet, and a coil about the discharge chamber. The system further includes an RF cathode proximate the discharge chamber outlet of the RF ion thruster for ion beam neutralization. The RF cathode includes a discharge chamber having a gas inlet and an outlet and a coil about the discharge chamber. A tank for containing iodine in solid form and a heater associated with said tank to produce iodine vapor. A feed subsystem fluidly couples the tank with the RF ion thruster discharge chamber gas inlet and with the RF cathode discharge chamber gas inlet.Type: ApplicationFiled: February 6, 2017Publication date: January 25, 2018Inventors: Michael Tsay, John J.

Patent number: 9296002Abstract: A sprayer portable on the back for spraying liquids comprises a tank (2), a hand lever (4), a pump (12) and a pressure vessel, wherein the pressure vessel is formed by a hollow space in the hand lever (4) and the pump (12) is arranged in the hollow space. The piston rod (13) of the pump is rotatably connected to a lever element (15) of the hand lever. A connecting sleeve (16) for a hose with a spray nozzle is integrated in the hand lever. The compact configuration of the sprayer allows a larger tank volume and more convenient operation. The sprayer can be manufactured at low cost due to the small number of components.Type: GrantFiled: April 25, 2013Date of Patent: March 29, 2016Assignee: Birchmeier SprühtechnikInventors: Jürg Zwahlen, Claudio Carrozza, Michael Zaugg

Patent number: 9139963Abstract: The invention relates to a portable scattering apparatus (1) for storing and dispensing granular material, especially pourable bulk material on a surface, e.g. of grainy fertilizer on a lawn surface, or scattering material on slick roads or paths. The scattering apparatus (1) contains a closable container (3) and a handle part (2) connected to the container (3) for dispensing the granular material. The handle part (2) comprises a lock chamber (4) in the connecting region of the container (3) for controlling the flow rate, and it is shaped into a distributor (5) at the front end. A valve (25) is arranged in the lock chamber (4), which valve can be actuated via a lever (11), which is pivotably held on the outside on the handle part (2). The lever (11) is connected via a valve stem (28) with the valve disk (26) of the valve (25).Type: GrantFiled: May 4, 2011Date of Patent: September 22, 2015Assignee: Birchmeier Spruhtechnik AGInventors: Jürg Zwahlen, Rolf Bandhauer

Patent number: 8197578Abstract: A liquid degasser for a space device including a gas permeable material configured for contact with a flow of liquid to be de-gassed on one side and a vacuum on the other side, and wherein the gas permeable material allows gas in the liquid to diffuse to the vacuum to remove the gas from the liquid.Type: GrantFiled: July 25, 2007Date of Patent: June 12, 2012Assignee: Busek Company, Inc.Inventors: Vladimir J. Hruby, Nate Demmons, Tom Roy, Doug Spence, Eric Ehrbar, Jurg Zwahlen, Charles Gasdaska

Patent number: 8091744Abstract: The invention relates to an arrangement for pouring free-flowing media out of a container. The arrangement contains a pour-out valve (3, 50) which can be specifically opened and closed by the user via an easy to operate actuating device (9), and thus allows a controlled pouring-out action. A pour-out tube (2) arranged in a pivotable manner on the container (1) makes it possible, depending on the position of the pivoted pour-out tube (2), to lock or unlock the pour-out valve (3, 50) using a blocking device. Locking the pour-out valve in the closed position prevents accidental opening of the pour-out valve (3, 50). The arrangement according to the invention also contains a venting valve (8), which can likewise be locked in the closed state. A compression spring ensures that, in the rest state, that is to say when the actuating device (9) is not actuated, the pour-out valve (3, 50) seals off the spout and the venting valve (8) is likewise closed.Type: GrantFiled: February 27, 2007Date of Patent: January 10, 2012Assignee: Birchmeier Sprühtechnik AGInventor: Jürg Zwahlen
