Title: Mains suppression inductor (filter) for a telecommunications apparatus
Inventor: GOSEBERG WALTER DIPL ING
IPC: H01F17/04
Filed: 1988-03-26
Abstract: The windings (S1, S2) which are located in the current path and form a low-pass filter have unavoidable winding capacitances which adversely influence the effect of the low-pass filter. The object is to reduce the influence of these capacitances. Those ends (c, d) of the windings (S1, S2) which are located side by side and between which the maximum capacitance acts are connected to the inputs (a, b) or the outputs (c, d) of the low-pass filter, where the capacitances do not produce any disturbing effect.

Patent DE-3818020-A1 (DE)
Title: Electromagnetic relay
Inventor: MINKS WERNER
IPC: H01H50/16
Filed: 1988-05-27
Abstract: In the case of electromagnetic relays, in particular flat-type relays, having an E-shaped magnet system and, projecting in the air gap thereof, pole plates of the transversely moveable armature, the pole faces of the outer limbs and of the magnet core are arranged in mutually parallel planes. This requires exact alignment of these faces with respect to each other, in order to eliminate tilting of the armature. By virtue of the convex design of the stop faces of the magnet core, only the pole faces of the outer limbs need now be aligned parallel to each other. It is suitable for miniature flat-type relays with small width. <IMAGE>

Title: Configuration for recognising formats on surfaces - has television camera recording capabilities
Inventor: HOFFMANN JOSEF DR
IPC: G06K7/10
Filed: 1990-01-11
Abstract: A reading head is fitted for reading character symbols stamped on components (1).  This is fed by illumination (3) and receiving light (4) conductors which have terminators vertical to a reading surface. The ends are matrix-shaped.  Receiving light conductor ends lie between at least two illumination light conductor ends.  When the reading surface is placed on the component with the character symbols to be read, those areas in which the conductor ends lie almost on the surface reflect the light from the illumination light conductors onto the receiving light conductor to a lesser degree than in the areas at a greater distance from the component. The other ends of the receiving light conductors create an image of the character symbols stamped on the component.  This can be recorded by a television camera (2). USE/ADVANTAGE - Checks surface symbols by light conductors, can detect deeply embedded or embossed formats, suitable for photodetection.

Patent DE-4003415-A1 (DE)
Inventor: RIEGER MARTIN DR
IPC: H04N5/60
Filed: 1990-02-05
Abstract: In multi-standard television receivers, in which the second audio intermediate frequency is converted into a constant frequency regardless of the current reception standard, external filters and demodulators of very high quality and selectively are needed for filtering and demodulating the second audio intermediate frequency. The purpose of the invention is to process audio intermediate frequencies more simply. Upstream of the mixing stage which converts the first into the second audio intermediate frequency there is a filter, the bandwidth of which is tuned to the entire frequency spectrum of the first audio intermediate frequency and serves for preselection and downstream of the mixing stage there is a filter arrangement which is tuned to the frequency spectrum of the second audio intermediate frequency  and produces a fine-selection of the second audio intermediate frequency.

Patent DE-4018967-A1 (DE)
Title: Polycrystalline silicon blocks with column crystallised structure
Inventor: PRIEWASSER GEORG
IPC: H01L31/04
Filed: 1990-06-13
Abstract: Polycrystalline Si blocks are formed by melting raw material in a melt position and transferring melt continuously or discontinuously into a crystallisation container. The feature is that during the start of this process in the Si present in the crystallisation container a crystallisation front is formed. This front is stabilised by a heating zone, pref. 10-50% of the dia. of the container, currounding the container. This zone is pref. heated by induction. As the container is gradually filled the heating zone moves up relative to the container bottom to make the crystallisation front move up with the filling height, which is assessed by the weight of the container. The depth of the layer of molten Si, pref. 20-50 mm., is controlled by the supply of molten Si and the supply and removal of heat. A flat crystallisation front is pref. maintained which moves up at a rate of up to 4 mm/min.

Title: Ball pen instrument - has replaceable ink reservoir which is retained in pen barrel by interlocking projections
IPC: B43K24/08
Filed: 1991-03-14
Abstract: A writing instrument, in particular a ball pen, has a barrel (3) which encloses a spring-loaded ink reservoir which can be moved longitudinally against a compression spring (4).
