Patent number: 5699029Abstract: A high performance bandpass filter is produced by adding one or more "simultaneous couplings" to a conventional resonant cavity filter. A "simultaneous coupling" is created when a filter's input or output signal, normally coupled to a filter's first or last cavity respectively, is coupled to one or more other cavities. Each simultaneous coupling causes a finite-frequency insertion loss pole to be created, which produces a quasi-elliptic frequency response on its side of the passband. These poles may be placed on the left and/or right sides of the passband, so that both symmetric and asymmetric quasi-elliptic frequency responses are realizable. A diplexer constructed from two such bandpass filters has the extremely sharp selectivity provided by two asymmetric bandpass filters, thus providing a high degree of receive/transmit isolation.Type: GrantFiled: April 30, 1996Date of Patent: December 16, 1997Assignee: Hughes ElectronicsInventors: Frederick A. Young, Keith N. Loi, Richard L. Bennett

Patent number: 5686186Abstract: A process for making a thermoformable conductive plastic laminate for use in making plastic parts adapted for electrostatic spray painting of a uniform high quality paint finish includes forming a matte release coated casting sheet, casting an electrically conductive polymer in thin film form on the casting sheet, drying to form a conductive primer coat, and transfer-laminating the conductive coating to a thin, thermoformable plastic face sheet. The matte release coat has a fine particulate filler that transfers a micro-toughened matte surface to the conductive primer coat. The conductive primer includes a polyester resin containing a fine particulate conductive material such as carbon black and, preferably, an anti-blocking agent such as fumed silica. The primer coated face sheet can be thermoformed and bonded to a underlying plastic substrate panel.Type: GrantFiled: June 7, 1995Date of Patent: November 11, 1997Assignee: Avery Dennison CorporationInventors: Howard H. Enlow, Scott W. Huffer, Frederick Young, William J. Buehne

Patent number: 5534881Abstract: A microwave cavity filter (30, 30A) is formed of a section of waveguide (36, 114) terminated by end walls (38, 40, 44, 166, 168, 176) to form cavities (32, 34, 32A, 34A) wherein ridges (100, 102, 118, 120) are disposed longitudinally within a cavity and extend from the cavity wall partway to a central region (104, 124) of the cavity. In a preferred embodiment of the invention, the ridges are disposed symmetrically about a central plane (144), each ridge having a first component (106, 122) perpendicular to the central plane and a second component (108, 126) parallel to the central plane. A cross-sectional shape of a filter cavity may approximate a semicircle wherein one wall section (88, 130) of the filter cavity is disposed within a diametric plane (216) of the cavity. The end walls of the cavities may be constructed as iris plates with apertures (82, 182, 184, 186, 190) for coupling energy of selected modes of electromagnetic resonance within the respective cavities.Type: GrantFiled: August 31, 1994Date of Patent: July 9, 1996Assignee: Hughes Aircraft CompanyInventors: Frederick A.

Patent number: 5518786Abstract: A flexible decorative sheet for use in surfacing an automobile body panel includes a first polyester carrier sheet having a high gloss surface, a clear coat of a weatherable optically-clear polymer containing fluorocarbon resin and an acrylic resin coated on the surface of the first carrier sheet, a tie coat on the clear coat, and a color coat containing a chlorinated polymer with dispersed pigments cast on the tie coat and dried. A pressure-sensitive adhesive layer is formed on a second polyester carrier sheet and then laminated to the exposed face of the color coat to form a pressure-sensitive, adhesive-backed composite paint coat between the outer carrier sheets which form protective removable backing sheets for the resulting laminate. The decorative sheet is applied to a substrate panel by pressure-sensitive adhesive bonding techniques, with the clear coat serving as a glossy, weatherable protective outer layer for the underlying color coat.Type: GrantFiled: July 21, 1994Date of Patent: May 21, 1996Assignee: Avery Dennison CorporationInventors: John R. Johnson, Keith L. Truog, Howard H. Enlow, William J. Buehne, Frederick Young

Patent number: 5012211Abstract: A microwave filter is composed of a set of circular cylindrical cavities arranged in cascade array and interconnected by irises having cross-slotted apertures for coupling electromagnetic power in two orthogonal TE.sub.113 modes. An input port is formed in a first of the cavities and an output port is formed in a last of the cavities. Each port is constructed as a transition between a section of rectangular waveguide and a section of circular waveguide, the section of circular waveguide being a portion of the first cavity and the last cavity, respectively, in the input and the output ports. The cross-sectional aspect ratio of the rectangular waveguide is 2:1. The ratio of a diameter of the cavity to length, as measured along a cylindrical axis in each cavity, is 0.26 thereby to provide for increased bandwidth while minimizing dispersion and transmission loss.Type: GrantFiled: September 2, 1987Date of Patent: April 30, 1991Assignee: Hughes Aircraft CompanyInventors: Frederick A. Young, Roy K. Rikimaru
