Patent number: 5754252Abstract: In a multi-standard television receiver in which a picture signal contained in a television signal and modulated on a picture carrier is converted to a picture signal intermediate frequency, and a stereo sound signal or two-tone signal contained in the television signal and modulated on two sound carriers is converted to two first sound signal intermediate frequencies, it is ensured for possibly simple filtering of the sound signals, also at different frequency spacings between the picture carrier and the sound carriers, that two sound signal filters (8, 9) having a fixed, predetermined filter central frequency are provided for filtering the stereo sound signal, and that frequency shift circuitry (6) is provided which, in dependence upon the frequency spacing between the picture carrier of the television signal and its sound carriers, shifts the picture carrier contained in the picture signal converted to the IF position to such a frequency that the sound IF signals of the first sound intermediate frequenciesType: GrantFiled: February 12, 1996Date of Patent: May 19, 1998Assignee: U.S. Philips CorporationInventors: Hans-Jurgen Kuhn, Ulf Buhse

Patent number: 5298425Abstract: Device for the positionally correct feeding of test strips to an analysis unit. The test strips 10 include a base layer and at least one raised test field fixed to one side of the base layer. The test strips are contained disordered with respect to their longitudinal axis rotation position in a storage container. A separation and position correcting device 1 serves to feed the test strips 10 individually one after the other in a defined position to the analysis unit. Simplicity of construction and reliable operation are achieved due to the fact that the separation and position correcting device 1 includes a position correcting stage 30 with two rolls, between which a narrow gap 35 exists. The rolls rotate so that the surface 31a of the first roll 31 moves in the region of the gap 35 from top to bottom, while the surface 32a of the second roll 32 moves from bottom to top. The first roll 31 includes peripheral raised webs 37 which are in alignment with test field-free regions of the test strips 10.Type: GrantFiled: February 9, 1993Date of Patent: March 29, 1994Assignee: Boehringer Mannheim GmbHInventors: Hans-Jurgen Kuhn, Horst Menzler, Stephan Sattler

Patent number: 4611226Abstract: A processing section for a television receiver for processing stereo/dual sound signals having a first sound carrier modulated by a first sound signal, and a second sound carrier modulated both by a second sound signal and by a pilot signal which, in turn, is modulated by a stereo/dual sound identifying signal. The processing section does not require a reference frequency from the synchronizing or intermediate frequency portion of the television receiver for recovering the pilot signal, but, rather, uses the pilot signal to control an oscillator in a phase-locked loop which loop is used to generate a signal for down-converting the frequency range of at least the modulated second sound carrier thereby obviating the need for expensive, precision filtering components.Type: GrantFiled: May 25, 1984Date of Patent: September 9, 1986Assignee: U.S. Philips CorporationInventors: Ulf H.
