Patent DE-4333276-A1 (DE)
Title: Method and device for testing a magnetic tape for fault locations
Inventor: WENGER HEINZ
IPC: G11B27/36
Filed: 1993-09-30
Abstract: A method is described for determining longitudinally extending fault locations in the case of a magnetic tape, in particular with reference to the occurrence of scratches, preferably in the case of video tapes which are intended for helical recording, for example in the VHS system. In this case, each track length is divided into a multiplicity of segments and, in the event that an RF video signal level drop of at least 6 dB has been established in a particular track length, a test is carried out as to whether such a level drop was registered in the preceding track lengths in the same segment. In the case of coincidence, a counter is activated over a predetermined interval, and the result is quantitatively indicated in the display, divided into colour-signal error or failure of the complete luminance signal.

Title: Method for determining spectral frequency components of radio-frequency voltage signals
Inventor: JAMITZKY PETER DIPL ING
IPC: G01R23/16
Filed: 1993-09-30
Abstract: In order to increase resolution accuracy when determining spectral frequency components from a radio-frequency voltage signals by means of the Fourier transformer method, it is proposed to increase the number of sampled values by adding to the measured sampled values zero values, the number of which amounts to double or quadruple the number of measured sampled values. <IMAGE>

Title: Inductive angle-measuring device
Inventor: CLAUSEN REIMER DR
IPC: G01D5/20
Filed: 1993-10-20
Abstract: An inductive angle-measuring device (1) is represented and described, which has a reference body (number) (2) realised as a rotationally symmetrical magnetic flux guide device, which has a primary coil (3) generating an alternating magnetic field after the application of an AC voltage, and has a secondary coil (4) provided in the alternating magnetic field generated by the primary coil (3), and has a measuring body (5) which influences the alternating magnetic field permeating the secondary coil (4) by means of its relative position with respect to the reference body (2). It holds for the inductive angle-measuring device (1) according to the invention that, on the one hand, magnets can be used without any problem as the material for the guidance of magnetic flux and, on the other hand, that problems do not occur even at relatively high rotational speeds, this being so because the measuring body (5) consists of electrically non-conductive material and is partially provided with an electrically conductive coating (7). <IMAGE>

Patent DE-4406483-A1 (DE)
Inventor: CONDUIT PATRICK IAN
IPC: H04Q1/457
Filed: 1994-02-28
Abstract: In a tone detector, a periodic signal is received and sampled in a level crossing detector (11) which gates (16) clock-pulse counts (15) to a processor which measures periods between crossings of the level by the signal. Pairs of maximum and minimum thresholds for signal periods corresponding to different desired tones are stored in memory (18) and consecutive periods of the signal are compared with the predefined thresholds. A primary tone detector, responsive to the comparison, counts instances when measured periods fall between a selected pair of minimum and maximum thresholds. Receipt of a first tone is confirmed when the primary tone detector counts to a first predetermined value. A secondary tone detector counts instances when measured periods fall between a new pair of minimum and maximum thresholds. The primary tone detector changes the selected pair of thresholds to the new pair of thresholds when the secondary tone detector counts to a second predetermined value. <IMAGE>

Abstract: Dans les soupapes à actionnement électromagnétique connues, le pointeau se compose d'un induit tubulaire, d'un tube de jonction se présentant sous forme de manchon et d'un élément de fermeture de soupape. Le carburant circule à l'intérieur du pointeau jusqu'à l'élément de fermeture de la soupape et entre ensuite dans le pointeau de soupape par l'intermédiaire d'alésages transversaux, en direction du siège de soupape. Ce nouveau pointeau de soupape (18) se caractérise en ce qu'au moins une section du pointeau de soupape (19) et une section de l'élément de fermeture de soupape ne forment qu'une seule pièce obtenue par emboutissage. Afin d'assurer la circulation du carburant en direction du siège de soupape (30), il est prévu de pratiquer dans la section du pointeau de soupape (19), par ex. deux moulures (61), la section de l'élément de fermeture de soupape (24) qui est hémisphérique présentant quant à elle des méplats (25). Le carburant circule ainsi le long de la périphérie extérieure de la section du pointeau de soupape (19). Le pointeau de soupape est particulièrement approprié aux soupapes d'injection de systèmes d'injection de carburant pour moteurs à combustion interne à allumage extérieur qui compriment le mélange.
