A method and an apparatus are described for controlling the braking force distribution in a vehicle between front and rear axles, such that at least while the vehicle is traveling in a curve, the braking force at the rear wheels is established individually in such a way that the difference between the velocity of that rear wheel and a front wheel velocity assumes defined values.

Wheel speeds on each side of the vehicle are added, and the sums are subtracted to form a difference VXU which is time filtered to produce a filtered difference VXG. As long as VXU does not exceed VXG by more than a speed dependent threshold, a signal indicating straight line travel is produced. This signal can be cancelled when VXG exceeds a vehicle dependent threshold and is also blocked when the vehicle speed falls below a minimum, when the ABS is operating, or when the vehicle is decelerating. The signal indicating straight line travel accounts for tire tolerance and can be used to control vehicle dynamics, for example by preventing an increase in brake pressure or engine braking when the vehicle is travelling in a curve.

A radio-controlled timepiece comprises an antenna in the form of a core on which a coil is mounted. The core includes a hole spaced from the coil and defining an axis oriented perpendicular to the coil axis. A printed circuit board is disposed in the hole such that electrically conductive tracks thereof are arranged in a plane lying within a center plane of the core.
摘要:
A vehicle brake system is described in which a lower brake pressure is fed in at the rear axle compared with the brake pressure of the front wheels. For the purpose of feeding in this brake pressure, the difference VD between the fastest front wheel speed and the slowest rear wheel speed is formed and compared with a threshold value which depends on the vehicle deceleration. An increase in pressure is undertaken until the threshold value is reached. The threshold value is, furthermore, larger in the case of travel in a straight line than it is in the case of travel in a curve.

The invention relates to an electrical circuit (1) for transmitting a useful analogue signal, which has a signal transmission path (16) with an input path (2) and an output path (3) and at least one switch (6), with which the useful signal which is carried on the input path (2) can be connected through to the output path (3) or the signal transmission path (16) can be interrupted. According to the invention, a compensation circuit (4) which substantially compensates for a distortion of the useful analogue useful signal generated by the at least one switch (6) when it is switched off (OFF) is provided, wherein the compensation circuit (4) is connected to a control terminal (G) of the at least one switch (6) and comprises at least one non-linear capacitance.

The disclosure concerns the enzymatic synthesis of stable analogues of nicotinamide adenine dinucleotide NAD/NADH and nicotinamide adenine dinucleotide phosphate NADP/NADPH, the so-called “carba-NADs”, i.e. analogues of NAD/NADH or NADP/NADPH, respectively, comprising a carbacyclic sugar instead of ribose.

The invention relates to a mold for the continuous casting of preliminary sections, in particular double T-shaped preliminary sections, such as beam blank sections or similar sections, wherein all the interior walls (7a to 7i) of the mold in the mold passage (8) have a tapered course (9 to 12) running linearly from top to bottom, said tapered course being dimensioned depending on the degree of shrinkage of the cast strand and produced by machining the interior walls (7a to 7i). In this manner, it is possible to optimally adjust the diameter of the mold to the shrinkage process of the cast strand in the region of the mold passage, even for large-sized sections.

The invention relates to a method and a device for guiding and orienting a strand (5) in a continuous casting facility for large-sized round sections made of steel or a similar material. In order to prevent the formation of cracks while the strand is oriented, the outer surface (15) of the strand is heated from above and from below inside the orienting track. For this purpose, porous burners (10, 17) are arranged in the discharge section of the directing track, the hot gas emitted from said burners flowing entirely around the outer surface (15) of the strand.

The invention relates to a method and a device for producing nitrogen fertilizer from organic waste products in the liquid phase (suspension, emulsion, solution) and for hygienizing the wastes or reducing the emissions by thermal treatment using mineral or organic additions.According to the invention, this is achieved by a method, wherein the waste product is heated at underpressure to temperatures between 40 and 90° C., the escaping gas containing carbon dioxide and ammonia is cooled down and introduced into an aqueous absorption agent, the nitrogen fertilizer formed thereby is discharged and the excess gas not having been absorbed and containing carbon dioxide is pumped back into the discharge container, wherein the underpressure generated at the beginning of the process by a vacuum pump is autogenously maintained by the progress of the process.Suitably, the return of the excess gas into the cycle is performed by either conducting it immediately above the waste product to be treated, or through a gas cooling system above the waste product to be treated, or dividing it and conducting a partial flow through the waste product and another partial flow above the waste product.Preferably, a gypsum suspension is used as an aqueous absorption agent.
