Patent number: 7909054Abstract: A fill valve for a toilet tank includes a multi-piece shank assembly. The shank assembly includes a first hollow member coupled with a second hollow member using a snap joint. The first hollow member has a tortuous outer surface, which together with the second hollow member forms a plurality of flow paths. The flow paths are configured to reduce water noise. The first and second hollow members are provided separately, resulting in simplified molding process and improved assembly automation.Type: GrantFiled: August 6, 2007Date of Patent: March 22, 2011Inventors: Tuan Le, Bill DeKeyser, Robert Collin

Publication number: 20070102053Abstract: A toilet fill valve device may function as a restrictor to reduce water flow, or as a regulator to cap water flow beneath a certain limit depending upon its orientation. If composed of a rigid material, the device functions as a restrictor to decrease water flow. If composed of a soft, flexible or compressible/expandable material, the device functions as a regulator as its walls expand to partially block fluid passageways when water pressure fills up a void within the device. The device includes a spiraled outer surface to provide a tortuous path for water to travel so as to reduce noise. The dual functionality of a regulator or restrictor may also be accomplished with the orientation of the device. Methods for manufacturing and using a toilet fill valve control device are also provided.Type: ApplicationFiled: November 8, 2006Publication date: May 10, 2007Inventors: Tuan Le, Bill DeKeyser, Robert Collin

Patent number: 4853652Abstract: A wide band low noise amplifier for metric waves, including a transistor connected by its emitter to the ground of the amplifier through two secondary windings, connected in series, of a first and second transformer, and coupled between its base and its emitter by the primary winding of the first transformer, one end of the primary winding of the second transformer being connected to the collector of the transistor, the output signal of the amplifier being taken from all or part of the primary of the second transformer and the number of turns of the secondaries of the transformers being very low so as to limit the leak inductance, which amplifier further comprises a first resistor connected in series with the two secondary windings and a second resistor connected between the output of the amplifier and the transistor base.Type: GrantFiled: March 17, 1988Date of Patent: August 1, 1989Assignee: Thomson-CSFInventor: Robert Collin
