Patent DE-4020878-A1 (DE)
Title: Headlamp control circuit for vehicle - has separate lamps for dipped beam and full beam and with progressive changeover in beam settings
Inventor: ODA GOICHI
IPC: B60Q1/14
Filed: 1990-06-29
Abstract: The headlamps have separate sources for the dipped beam and the distance beams. When switching from one beam to the other a control circuit progressively alters the beam intensities and provides a smooth changeover in the headlamp action. This prevents sudden intensity changes from blinding oncoming traffic and ensures an even illumination of the road for the driver. At least one of the lamps is a discharge type with the intensity controlled by DC convertion circuits and current level detectors. The other lamp can be a normal fillament type. Another mode of control for the discharge lamp is by varying the supply frequency. ADVANTAGE - Safer driving, less dazzle risk for other road users.

Filed: 1991-08-20
Abstract: A punch (1) is proposed for producing grating elements (20) according to the invention, the grating elements (20) being formed from a metal sheet as the punch (1) penetrates the latter. In its end region (6, 7, 8), with which it interacts with the sheet during the forming operation, the punch (1) comprises a stub (6) of essentially square cross-section, adjoining which is a pyramid-shaped end piece (8). Two opposite side faces (18) and (19) of the pyramid-shaped end piece (8) have essentially the same angle of inclination (b and a respectively) in relation to their centre line (10 and 9 respectively) whereas the common angle of inclination (b) of one pair (18) of side faces differs from the angle of inclination (a) of the other pair (19) of side faces. As a result, the two opposite sheet-metal tabs (25) are curved in such a way that their sharp-edged rim (28) points in the circumferential direction (U), giving a sharper grating disc (21). <IMAGE>

Inventor: GOLDAU RUDI
IPC: B02C13/09
Filed: 1991-08-27
Abstract: The invention relates to a process and device for crushing metallic and/or non-metallic material. The device consists essentially of a stator (1) and a rotor (2), the stator (1) having impact devices (10) and the rotor (2) having rotary strikers (11). The device has a feed (4) for the material to be crushed and an extractor (5) for the material from the device.

Patent DE-4133297-A1 (DE)
Inventor: FRISCH BERND-D
IPC: A61F11/00
Filed: 1991-10-08
Abstract: The device provides better spatial acoustics which are lacking especially when sound signals are reproduced via electro-acoustic equipment (e.g. loudspeaker boxes). The listener can affect the psycho-acoustic depth of the space over a vertical axis by individually adjusting the movable earpieces, i.e. he can change the front-rear location of sound phenomena according to his own sensitivity. The depth staggering (spatial depth of the sound image) depends upon the aperture of the earpiece and the spatial depth can be attenuated or amplified by opening and closing the movable earpieces. At the same time the device increases the volume and improves the clarity of spoken information. The supporting bracket makes it very easy to adjust the earpieces and the latter can be easily removed from the bracket itself. In addition, it ensures that the earpieces are adapted to the shape of the user's head in the best possible manner.
