  • Publication number: 20180023550
    Abstract: 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.

  • Patent number: 9296002
    Abstract: 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.

  • Patent number: 9139963
    Abstract: 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).

  • Patent number: 8197578
    Abstract: 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.

  • Patent number: 8091744
    Abstract: 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.

  • Patent number: 7932492
    Abstract: An electrospray device includes an electrospray emitter adapted to receive electrospray fluid; an extractor plate spaced from the electrospray emitter and having at least one aperature; and a power supply for applying a first voltage between the extractor plate and emitter for generating at least one Taylor cone emission through the aperature to create an electrospray plume from the electrospray fluid, the extractor plate as well as accelerator and shaping plates may include a porous, conductive medium for transporting and storing excess, accumulated electrospray fluid away from the aperature.
