Title: Method and a device for automatically determining the tread depth of vehicle tyres
Inventor: MOLITOR MARTIN DR ING
IPC: G01B17/00
Filed: 1993-05-21
Abstract: The invention relates to a method and a device for automatically determining the tread depth of tyres of vehicle wheels, in which a tyre arranged on a vehicle wheel is rolled over a measuring plate arranged in the floor of a measuring station, or is deposited on said plate. The tyre tread pattern is sampled along a measuring line aligned transverse to the rolling direction of the tyre, and the tread depth is determined in the process. The determination of the tread depth is undertaken as a distance signal in the manner of the tracing (contact) stylus method in an optical and contactless fashion using a triangulation unit which can be moved along the measuring line. Another possibility is to transmit an ultrasonic signal in the direction of the measuring line and to use the propagation time of this ultrasonic signal for the purpose of distance measurement.

Title: Sequence analysis of linear polymers
Inventor: SCHWERTNER HEIKO DR
IPC: C12Q1/6869
Filed: 1994-03-26
Abstract: For a sequence analysis of linear polymer substances, mol. ring structures are formed through covalent bonding of mol. carbon chains at a carrier material. When successfully slipped on, they are drawn onto the carrier by an electromagnetic field. This is followed by a covalent coupling of the linear polymer under scrutiny through the resultant monomer at the spacer. A block mol. is applied to the opposite ends of the polymer with a covalent bond, so that the ring structure has free movement along the polymer axis. Reversing the polarity of the electro-magnetic field forces the ring to spread over the polymer.
