Title: Sleeved spike for pneumatic tyre - with specified contours for rivet head and for sleeve
Inventor: LINDEN UNTO
IPC: B60C11/16
Filed: 1989-04-24
Abstract: A sleeved spike for pneumatic tyres on motor vehicles has on its flanged head several undulating radial ribs which contact the rubber with a much smaller surface then the total area of the spike. When the spike is at rest and at the  first contact wtih the road surface, the peripheral rib ends rest on the tyre rubber and the top of the sleeve is clear of the rubber.

Title: Regenerating hydrocarbon charged active carbon filter by steam
Inventor: HASPEL HANSJOERG
IPC: B01D53/02
Filed: 1989-12-05
Abstract: The system includes transmission cells defining different geographical areas, each having a transmitter for simulcast address transmission at a first data bit rate and for transmitting the address and a message at a second high data bit rate.

Patent DE-4012608-A1 (DE)
Inventor: STEINER GERD
IPC: H04N1/46
Filed: 1990-04-20
Abstract: A method and a device are proposed for carrying out a value determination of the register difference on contours occurring in the printed image (for example letters in negative writing) by means of a colour video camera 2. The signal of the colour video camera 2 carrying the colour information is subjected to a colour separation in accordance with the printed colours occurring during printing. A contour, which has been produced by printing at least two printed colours on top of one another thus results in at least two separations in the corresponding printed colours. To determine the register difference, the offset from one part-image (separation) compared with the other part-image is now calculated. According to the device, a frame buffer 4, a colour separation computer 5, a colour separation memory 6 and an image computer 7 are provided in addition to a colour video camera 2.
