Title: Method for detecting the roller test bench operation in a motor vehicle
Inventor: WELTER ANDREAS
IPC: G01P3/56
Filed: 1993-09-23
Abstract: In a method for detecting the roller test bench operation in a motor vehicle, the wheel speeds of both the front wheels of the motor vehicle are compared with a predetermined wheel speed threshold close to zero. In addition, the difference between the wheel speeds of the rear wheels of the motor vehicle is compared with a predetermined wheel speed difference threshold which is close to zero. Finally, a roller test bench operation is detected if both the wheel speeds of the front wheels of the motor vehicle are smaller than the wheel speed threshold and also the wheel speed difference of the rear wheels of the motor vehicle is smaller than the wheel speed difference threshold.

Title: Method for incorporating pharmaceutically active substances into hard and soft contact lenses to produce ophthalmological controlled release systems by means of diffusion-controlled sorption
Inventor: SCHIERHOLZ JOERG MICHAEL DR
IPC: A61K9/00
Filed: 1993-11-03
Abstract: The present invention describes a technical method which can be used to load prefabricated contact lenses or other ophthalmological polymers sufficiently with drugs within the range from 1 to 50% (by weight) without altering the fundamental structural properties. This method results in continuously controlled release systems with reproducible properties for achieving a physical and medical effect. With a sufficiently high loading (> 1% by weight), therapeutically effective release rates are achieved in the absence of toxic effects and minimisation of side effects on local use of, for example, mitomycin from a collagen carrier for intraocular fibroblast inhibition in cases of drainage of aqueous humour. The invention furthermore relates to the control of the kinetics of release within a wide range from 0 order release to t<2> proportionality by means of different evaporation or extraction techniques. The invention furthermore contains the possibility of increasing or reducing the duration of release in relation to the amount released. On practical use of the invention, every drug able to diffuse through the polymeric matrix and producing a local corneal or conjunctival therapeutic effect, and the esters, ethers, amides or salts of these drugs, are suitable.

Title: Energy production from biogas
Inventor: SCHMID WALTER
IPC: F02B3/06
Filed: 1994-03-03
Abstract: In a method for producing electrical energy, a diesel engine which drives a generator is operated using a combustion mixture of biogas and vegetable oils. The mixture is varied in such a way that the calorimetric combustion value of the mixture is kept constant. This is made possible in that the mixture ratio of biogas and vegetable oils is controlled as a function of the torque at the output drive of the diesel engine. By using vegetable oils, the varying proportion of methane gas in the biogas can be compensated. At the same time, the method makes possible sensible utilisation of used vegetable oils.

IPC: B60R16/023
Filed: 1994-04-28
Abstract: A computer in a car uses sensors to help it calculate the energy flows. The sensors are for speed, weight, fuel available and/or the time variation of these. Stored data include wind resistance, roll resistance and gearbox resistance. The actual load is keyed in manually. The car weight is found from a sensor in the suspension system. Another sensor measures the vehicle height or inclination. The computed energy of the car is updated regularly by increments which depend on the change in potential energy and kinetic energy over the time interval, and also the energy of the fuel used in this interval.
