Title: Vehicle headlamp
Inventor: ALBER FRIEDER DIPL ING
IPC: F21S8/10
Filed: 1996-05-25
Abstract: The headlamp has a concave reflector 910), a bulb 912) and a lens (20). The light beam is reflected with a given characteristic. Between the reflector and the lens is an additional annular reflector (22) which gives a more strongly horizontal light scattering than from the main reflector. The beam from the additional reflector also has a much smaller range than that from the main reflector. The additional reflector is either joined to the main one or made as a one-piece item with it. It is basically a section of a cylinder whose axis is coincident with that of the main reflector. The lens is flat and has no, or at least only weakly effective, optical elements.

Title: Rolling-friction-free dynamo e.g. for bicycle with parking and emergency light
Inventor: REISER ANDREAS
IPC: B62J6/20
Filed: 1997-02-04
Abstract: The dynamo produces energy by the movement of the wheel using pedal power. With high speeds approximately above 12 Km per hour a braking effect is engaged e.g. with an eddy current brake. The energy is rolling friction free otherwise as that produced by a side runner. The energy production is carried on during the total journey time of the bicycle. The energy charges an accumulator, which serves as the voltage source for all the user circuits. The bicycle normal speed is not sufficient to operate the parking light yet emergency light can be operated. A styrene product material can be used for the magnet holder. Coils are fixed symmetrically right and left of the rotating wheel. The energy production results in a non-contact manner. The energy is produced directly by the rotation of the bicycle wheel without drive or gearing. Only air and bearing friction also an ohmic resistance due to the temperature in the coils occurs.
