Patent DE-3801721-A1 (DE)
Title: Circuit arrangement for operating a fluorescent lamp
Inventor: VOVAN ROBERT
IPC: H05B41/24
Filed: 1988-01-21
Abstract: A description is given of a circuit arrangement for operating a fluorescent lamp, comprising a fluorescent lamp whose heating filaments are connected in each case with one end to the output winding of a high-reactance transformer of an invertor and in each case with the other end to a starter. To ensure an orderly function of a starter designed for 50 Hz mains operation on an invertor operating at high frequency, a rectifying element and a switching device which automatically bridges said rectifying element electrically after the lamp has started are connected in parallel in the connection between the output winding and one of the heating filaments.
Patent DE-3817635-A1 (DE)
Title: Process for the separation or enrichment of isotopes or molecules
Inventor: FREITAG ROLF
IPC: B01D59/48
Filed: 1988-05-25
Abstract: The separation or enrichment of isotopes or molecules is sometimes currently achieved with very high expenditure. The novel process is to separate or enrich diamagnetic atoms or molecules by the kilogram with low expenditure and to separate or enrich the other atoms or molecules with moderate to high expenditure. The separation of isotopes or molecules is achieved by the neutral atomic or molecular beams (1) flying through an inhomogeneous electric or magnetic field (3). In the case of sufficient velocity selection (2), the beams split into monoisotopic or unimolecular beams (4) owing to the directional quantisation, different electric or magnetic moments and differing masses. Enrichment proceeds by very strong to weak different accelerations or forces acting on the atoms or molecules in the inhomogeneous electric or magnetic field and therefore, for example, in the case of diamagnetic elements, the isotopes having a nuclear moment  NOTEQUAL 0 (e.g. <3>He) can be "sucked off" or "distilled off" from the other isotopes (e.g. <4>He). Enrichment or separation of isotopes or molecules. <IMAGE>

Patent DE-3905657-A1 (DE)
Title: Flexible supporting film
Inventor: ADLUNG HERBERT
IPC: H01L23/498
Filed: 1989-02-24
Abstract: In the case of flexible supporting films having integrated electrical components, the problem often arises of the components being damaged during the processing of the supporting film. In the case of a flexible supporting film which contains conductor tracks, contact surfaces and electrical components connected between the contact surfaces, this problem is solved by the film region which is provided for retention of the components consisting of a tongue which in each case projects into an opening which is incorporated in the film. The tongue is in this case arranged in such a position that the deformation on the contact surfaces is reduced in the preferred deformation direction of the entire film.

Patent DE-3906741-A1 (DE)
Inventor: CHUCHOLOWSKI CORNELIUS DR
IPC: B62D113/00
Filed: 1989-03-03
Abstract: In a process for controlling the rear wheels of motor vehicles infunction of a deflection of the front wheels, the steering angles for the front and rear wheels are mechanically decoupled and a transmission element adjusts the angle of deflection of the rear wheels in function of the deflection of the front wheels, the rear wheels are briefly and reversibly deflected in the opposite direction to the front wheels and are then deflected in the same direction as the front wheels. The adjustment of the rear wheels is controlled. When the angle of deflection of the front wheels is stationary or not equal to zero, the angle of deflection of the rear wheels is reset to zero after reaching a maximum value. This results in an appreciable increase in driving dynamics in comparison with a conventional vehicle. In stationary cases, alternating load reactions are easily mastered while the angle of deflection of the front wheels is kept constant.

Title: Construction kit consisting of structural elements and couplings
Inventor: KRAENZLER OTTO
IPC: A63H33/04
Filed: 1989-03-30
Abstract: For models of multiply interlinked structures such as three-dimensional lattice-works and frameworks, mechanically locking or clamping connections are laborious and time-consuming to produce with the known screwless construction kits. The occurrence of torsional and bending forces is unavoidable. The new type of construction kit is intended to permit the realistic, professional construction of torsion-free tensile and compressive structures without tools and with a minimum use of force. In order to permit any desired angular positions, appropriately prepared structural elements are stuck onto spherical couplings by means of magnetic or tuck-and-close connectors. The magnetic design contains permanent-magnet couplings (2a) and rod-shaped structural elements (1), which bear ferromagnetic endpieces (3a) with contact surfaces (4) shaped to fit the couplings (2a). In the tuck-and-close design, the couplings are coated with one part of a tuck-and-close connection and the contact surfaces of the structural elements with the other part. Depending on the design, the construction kit can be a constructive toy, a model construction kit or a means of instruction. The connecting technique is variable and wear-free and permits very simple dismantling and reuse of all structural elements as desired. Skill and spatial perception are encouraged in an entertaining manner. <IMAGE>
Patent DE-3914555-A1 (DE)
Inventor: WELLHAUSEN HEINZ PROF DIPL ING
IPC: G01L1/20
Filed: 1989-05-03
Abstract: The invention relates to a pressure sensor with which an electric signal proportional to pressure may be generated, where, when an elastomeric body (1) is distorted, an electric current passing through it experiences a changing electrical resistance; the elastomer of the body (1) has a constant electrical conductivity independent of pressure. In the neutral state the body's small contact area (5) with a high contact resistance comes into contact with an electrically conductive pressure area (2) and the contact area (5) may be enlarged by applying a force P on the body towards the pressure area (2) with the distortion of the body, so that a reversible reduction in the contact resistance (R) may be produced. The body is spherical or cylindrical in shape.

Patent DE-3921807-A1 (DE)
Inventor: HOSTER THOMAS DR ING
IPC: F23K3/02
Filed: 1989-07-03
Abstract: Described is a process for heating a metallurgical furnace, in particular an arc furnace charged with scrap metal or a similar solid material. Oxygen and fuel are fed in through the furnace wall by at least one burner located above the melt, the fuel being supplied in a carrier-gas stream which completely surrounds the oxygen feed line. The process is particularly cost-effective owing to the fact that 4-15 kg/t of coal dust of particle size <200  mu m in an inert-to-slightly reducing carrier gas is used as the fuel, being fed in at a speed of at least 45 m/s, at least while the charge is melting, and being burnt in a diffuse flame in stoichiometric to slightly greater than stoichiometric proportions in oxygen emerging from the burner at about the speed of sound and at a pressure of at least about 1 bar. Also described is a burner particularly suitable for use in this process.
