Patent number: 9287600Abstract: A conductor is formed of a first portion to define a first area in a plane that is substantially perpendicular to a first magnetic field direction in a first cavity resonator and a second portion to define a second area in a plane that is substantially perpendicular to a second magnetic field direction in a second cavity resonator. Inductive current generated in the first portion flows in substantially the same direction as current in the second portion. The conductor may be deployed in an aperture between the first and second cavity resonators to couple or cross-couple the first and second cavity resonators. The conductor may also be deployed to couple or cross-couple cavity resonators in a filter implemented in a broadcast- or base station.Type: GrantFiled: March 26, 2014Date of Patent: March 15, 2016Assignee: ALCATEL-LUCENT SHANGHAI BELL CO., LTD.Inventors: Yan Cao, Dieter Pelz

Patent number: 7015771Abstract: A directional coupler uses non-metallic slotted spacers at the edges of a pair of coupled lines. The spacers are adjustable in their vertical position and thereby provide continuous coupling fine-adjustment. The spatial relationship between the coupled lines is therefore adjustable and does not depend upon extremely tight manufacturing tolerances.Type: GrantFiled: July 22, 2004Date of Patent: March 21, 2006Assignee: AlcatelInventor: Dieter Pelz

Patent number: 6208221Abstract: An adjustable microwave diplexer comprising two combline filter sections (A and B). Each filter section has at least three tunable resonator elements (1,2,3 and 4). Non-adjacent resonator elements of one section (A) are inductively coupled by an adjustable coupling element (20,21), and non-adjacent resonator elements of the other section (B) are capacitively coupled by an adjustable capacitor element (31). This arrangement provides the means to achieve adjustable transmission zeros above the passband of filter A and below the passband of filter B to provide the diplexer with two highly selective filters.Type: GrantFiled: May 13, 1999Date of Patent: March 27, 2001Assignee: AlcatelInventors: Dieter Pelz, Natalie Trembath

Patent number: 6167636Abstract: In a process for thermally utilizing wet spent grains (1), the wet spent grains (1) are mechanically predried in a first drying stage (2), thermally dried in a further drying stage (4) and finally thermally utilized by burning or gasification. In order to be able to realize a process of this kind economically, the mechanically dehydrated spent grains (15) in the further drying stage (4) are heated by the aid of a smoke gas occurring within the energy system of a brewery.Type: GrantFiled: May 19, 1999Date of Patent: January 2, 2001Assignee: Brau-Union {umlaut over (O)}sterreich AktiengesselschaftInventors: Leopold Werner Kepplinger, Dieter Pelz, Gerald Zanker

Patent number: 6118355Abstract: A dual band combiner for combining two frequency bands having a 2:1 relationship, e.g. 900 MHz and 1800 MHz. The combiner comprises an upper frequency bandpass filter section and an upper frequency bandstop filter. The bandpass filter section comprises two open-end resonators whose lengths are 1/2 wavelength of the upper frequency band, and the bandstop filter comprises three open-end resonators whose lengths are 1/4 wavelength of the upper frequency band. Because of the 2:1 frequency relationship pronounced selectivity-enhancing transmission zeros are produced at the lower frequency band, thereby providing a combiner that has high isolation between ports while maintaining low insertion loss.Type: GrantFiled: June 8, 1999Date of Patent: September 12, 2000Assignee: AlcatelInventors: Dieter Pelz, Noel McDonald

Patent number: 6025764Abstract: An arrangement for adjustably coupling a radio frequency input port to a resonator element of the filter. The arrangement comprises a resilient conductor (19) which extends from the input port (15) into the electric field of a resonator element (2). The remote end of the resilient conductor resiliently abuts the point (20) of an adjustment screw (20a). Operating the screw moves the resilient conductor in relation to the electric field and alters the capacitive coupling between the input port and the resonator element for fine tuning the impedance match of the input to the filter.Type: GrantFiled: June 30, 1997Date of Patent: February 15, 2000Assignee: Alcatel Alsthom Compagnie Generale d'ElectriciteInventors: Dieter Pelz, Natalie Trembath
