Inventor: HAGEMANN HANS-JUERGEN DIPL ING
IPC: H02M1/12
Filed: 1992-06-12
Abstract: The circuit is inserted between a current regulator (8) and an AC network (14) and uses a duplex choking coil (10) with a primary winding (11) coupled to the current regulator and an anti-parallel secondary winding (12) coupled to the AC network. Both windings of the duplex coil are connected to a tap-off (16) which is coupled to a tuned LC filter (18) for damping the signal harmonics, connected to earth in the case of a single-phase system and to the neutral point in the case of a 3-phase system.

Title: Multicylinder combustion engine with exhaust gas recycling - has dual-inlet cylinders arranged in two gps. with one or more injectors downstream from flaps
Inventor: KRAEMER MICHAEL DR ING
IPC: F02M26/42
Filed: 1992-07-10
Abstract: Air is drawn through a filter (21), a mechanical supercharger with a clutch (22a) and bypass valve (24), and an air cooler (25) to an inlet pipe (10) which is branched (10a,10b) to a manifold (11) in two parts sepd. by a resonance flap (20). Each branch feeds a gp. of cylinders (6) each having a flap (17) in one inlet (4) but not in the other (5). All cylinders exhaust (3) through a three-way catalytic convertor (30) followed by intermediate and final silencers (31,32). USE/ADVANTAGE - In an engine with two sparking plugs (8,9) and inlet valves per cylinder, a stoichiometric fuel/air mixt. gives better economy and less NOx without degradation of hydrocarbon and CO emissions.
Patent DE-4227025-A1 (DE)
Inventor: KELLER KLAUS DIPL ING
IPC: G11B15/44
Filed: 1992-08-14
Abstract: Dictation apparatuses, in particular hand-held dictation apparatuses, must have a device which allows a short rewind function after interrupting the recording or playback function, in order to be able to play back the passage of text last recorded or played back. If an apparatus only has a rewind function, the length of tape rewound will depend very much on the feeling of the user of the apparatus and will correspond only rarely to the desired length of tape. In the case of apparatuses with a short rewind device, although short returning of the magnetic tape is possible to a greater or lesser extent, further rewinding of the magnetic tape, for example to the beginning of the tape, is only possible by actuating a separate rewind button or if the adjustable short rewind time can be prolonged correspondingly. It is proposed to rewind the magnetic tape after switching on the rewind initially only by a time T1, then to stop for a time T2 and, once T2 has elapsed, either to continue rewinding or, by manual ending of the rewind function, to return to playback mode and listen to the text of the short returned piece of tape.

Title: Min. flow quantity valve for pump system - with auxiliary valve section ensuring min. flow quantity when pump load is disconnected
Inventor: DRESSELHAUS DIETER DR RER NAT
IPC: F04D15/00
Filed: 1992-09-14
Abstract: The valve has two separate housing halves (2A,2B) on the pump side and the load side, which are screwed together and provide coaxial spindle guides (12,115) for an axially displaced valve spindle (6) carrying a valve element (5) cooperating with a valve seat (51) in the housing half (2B) on the load side. An auxiliary valve section has an axial bore (60) leading to a radial bore (61), communicating with an annular space (80) around the upstream spindle section, in dependence on the spindle position. This annular space is sealed via a valve element (8) at either side, with a radical pipe (10) leading to an auxiliary flow connection (13) on the outside of the valve housing. ADVANTAGE - Eliminates transverse force of valve spindle guide with easy assembly and fitting of valve seals.

The gel is made by reacting polyisocyanate (IV), (I), opt. catalyst, accelerator, filler and additives. The mean functionality (F1) of (IV) is 2-4 and that (F2) of (I) is 3-6, and the isocyanate characteristic no. K is 15-70. K is given by the formula K = ((300+/- X)/(F1-F2)-1)+7 (X is not over 120, esp. not over 90). USE/ADVANTAGE - The foams (esp. formed as layers on flat surfaces) are used as adhesive plasters, wound dressings, bandages, protective materials, compresses, etc., partic. for deep wounds (over which several thin layers of material can be applied).

Title: Road condition detecting unit identifying state of road surface lying before moving motor vehicle - uses two adjustable light transmitting and receiving systems at different angles of elevation and supplying evaluation circuit correlating receiver signals
Inventor: BOEHM MANFRED DR ING
IPC: G08B19/02
Filed: 1992-10-17
Abstract: Light signals reflected from a road surface section (SB), illuminated by respectively assigned light transmitters, are detected and supplied to an evaluation unit (A). The two light transmitting and receiving systems (SE1, SE2) are so arranged at the vehicle, that the same road surface section (SB) is illuminated at different elevation angles and optically scanned. The evaluation unit (A) carries out a correlation of the signals detected from the two light receivers. The correlation peak values are compared with stored values derived empirically for various surface roughnesses. An appropriate reaction is activated if the comparison result indicates a condition of lower roughness, e.g. due to ice. ADVANTAGE - Alterations in road surface condition due, e.g. to rainfall or icing, can be detected.

Title: Lining system of bricks of two basic sizes - for lining domed bottom e.g. of steel converter
Inventor: POESCHL JOHANN ING
IPC: F27D1/04
Filed: 1993-01-28
Abstract: (A) In a system of sized bricks for lining domed bases esp. of metallurgical vessels, the bricks have six planar faces (i.e. a hot face, a cold face, two side faces and inner and outer faces) and are designed for laying in concentric rings, in each of which the side faces of the bricks are adjacent one another, the outer faces of the bricks of one ring being adjacent the inner faces of the bricks of the next ring. The novelty is that (i) bricks of two basic sizes are used, the first size bricks having a certain distance between the imaginary intersecting line of the inner face with the outer face and the hot face and the second size bricks having a greater distance between the imaginary intersecting line of the inner face with the outer face and the hot face; and (ii) at least three positions are provided within each basic size, the bricks of different positions having side faces which are inclined differently w.r.t. one another and the bricks of each position having parallel side faces. (B) Also claimed is a metallurgical vessel with a steel casing (231) having regions of spherical or toroidal segmental shape and having a brick lining (23) as described above. USE/ADVANTAGE - The lining is useful for the bottoms of steel converters and similar vessels. The system allows brick lining of spherical and toroidal segment surfaces with any radius (within certain limits) using a small number of brick types, any small gaps in the lining being insignificant.

Title: Lensless visual aid for close range
Inventor: WEINZIERL RUDOLF DR DR
IPC: G02C7/16
Filed: 1993-05-27
Abstract: The invention relates to a near-vision aid which uses, in the optically effective range, the converging lens-like property of narrow and very narrow diaphragms with an extremely thin layer in order to produce an exactly sharp image of an object, which is at close range, at the centre of the retina of the human eye, even though the field of view (viewing field, visual field) is small and the luminance is reduced. The optics presented is not intended to, and cannot, represent an alternative to the conventional near-vision aids. The intended main purpose is to aid people who have a serious visual impairment but still retain at least a fraction of a central retina function. The optics presented is, furthermore, best suited for short-term operation and for emergencies where no other near-vision aid is available. The situations considered here are reading maps in cars, finding entries in telephone directories, reading menus and the like.   Since the production costs for the diaphragm optics can evidently be kept very low, it would also be possible for monocular visual aids to be packaged together, for example, with the leaflets, which are often illegible for elderly people, which accompany medicine (drugs). The optics is mechanically completely robust and of extremely small dimensions and can be accommodated in any handbag, in any purse and in any jacket pocket.
