Publication number: 20150115053Abstract: The steam eyelet(s), mounted on steam dispersion tube(s), part of a steam dispersion system, has an interior cavity fed with steam, a through passage, a steam entry port and a steam exit port. The exit port is partly closed by a sloped throat which captures steam condensate and the steam entry port has a drain slot which drains condensate into the dispersion tube cavity. The eyelet's through passage progressively narrows at the exit with a shallow and then steep slope. A protruding lip reduces facial formation of condensate. A method reduces condensate spitting by accumulating condensate in the interior of the eyelet which, when it reaches a certain volume, drains the condensate bubble-droplet with an inboard interior eyelet surface disruption near the steam entry. Surface tension of the condensate bubble-droplet is used to drain the bubble-droplet at the disruption, causing an out-flow of the bubble-droplet in a direction contrary to steam flow.Type: ApplicationFiled: December 13, 2013Publication date: April 30, 2015Applicant: National Environmental Products Ltd.Inventors: Zev W.

Publication number: 20130234057Abstract: A valve for agricultural spraying machines. The valve is used to control a flow rate of a spray medium in accordance with a valve position. For this purpose, the valve comprises an electrically operated actuator, which can change the valve position of the valve. The valve comprises an electrical energy store, which stores electrical energy for operating the actuator. The valve further has a control and evaluation unit, which is configured to charge the electrical energy store and to control the actuator. The electrical energy store has a capacity that ensures at least two switching operations of the valve. The control and evaluation unit is configured to control the actuator to generate a periodic movement with a defined number of movement strokes and a defined amplitude for shaking free the valve by the help of the electrical energy store if the valve is soiled or gridlocked.Type: ApplicationFiled: April 25, 2013Publication date: September 12, 2013Inventor: Norbert Muller

Patent number: 8418938Abstract: A shower head includes a nozzle, a connector mounted on an open top of the nozzle, a fastening member secured on the open top of the nozzle and abutting the connector to limit the connector on the nozzle, and a bushing mounted in the connector. Thus, when the water flows through the shower head, the ambient air is introduced through the connector and the bushing to break the vacuum state in the shower head and to perturb the water flow in the shower head so as to produce a turbulent flow in the shower head so that the water flow injected from the nozzle is broken and divided into multiple straight water beams and multiple irregular water bubbles so as to increase the flushing angle and area of the shower head.Type: GrantFiled: May 4, 2010Date of Patent: April 16, 2013Assignee: Sunrise Shower Products Co., Ltd.Inventor: Kun-Chih Chen
