Abstract: A television transmission system replaces the standard FM audio portion of a television signal with digital audio. Three digital audio channels are time division multiplexed on the sound carrier, using combined multi-phase and AM modulation. The audio signals are digitized using adaptive delta modulation techniques. Video vertical and horizontal framing, as well as the audio carrier phase reference, audio data bit time and frame reference, and various control data is carried using AM modulation. The digital audio information is carried using multi-phase modulation. The composite data stream may be serially encrypted to provide security and prevent unauthorized reproduction of the video and/or audio portions of the television signal.

Title: Braking system for a steerable vehicle with 2 or more axles with at least rear axle driving
Inventor: REBHOLZ WALTER
IPC: B62D9/00
Filed: 1988-04-23
Abstract: In a steerable vehicle with two or more axles and with at least rear axle drive, the conventional brake system consisting of service brake device and parking brake device, possibly complemented by an antiblocking system and an antislip control, is assigned an auxiliary brake device for a one-sided braking of the vehicle, the said auxiliary braking device operating in a steering angle-dependent manner. This auxiliary braking device can be actuated as required and, if a predetermined minimum steering angle of the steered wheels is undershot at a driving speed below a specific value, a one-sided braking of the wheel or wheels on the inside of the bend, at least of the driven rear axle or axles of the vehicle, is effected by selective provision of brake pressure. In this way, it is ensured that tight bends are passed through in a track-holding manner following the steering angle to the greatest extent without the vehicle being forced over to the outside of the bend. <IMAGE>

IPC: G06F7/48

Abstract: In technical/scientific calculations with floating-point numbers on computers, the results can be falsified by an accumulation of rounding errors. By converting the floating-point numbers into fixed-point numbers and subsequently carrying out the arithmetic operations in the fixed-point format, these rounding errors can be avoided. The arithmetic unit in the computing system then processes the fixed-point numbers. For this purpose, it is necessary that the fixed-point numbers are arranged in the correct position in the registers which are accessed by the arithmetic unit. In the case of an extensive floating-point format, this leads to a correspondingly large fixed-point format and thus to a correspondingly large register. To provide the possibility of multi-user operation or multi-task operation in a computing system which processes such floating-point numbers, a memory (SP) is provided which is divided into equal-length sections (AB). Each section (AB) is furthermore subdivided into equal-length segments (SG). Each section has such a length that one fixed-point number can be stored in long format. In addition, management data can be specified in a segment (SG0) of the section which specify the area of the fixed-point number in long format in which the data to be processed are contained. In the segments of the sections, floating-point numbers can also be stored. The allocation of the sections to fixed-point numbers and floating-point numbers is variable and can be adapted to the individual tasks to be executed. The arithmetic unit of the computing system can operate in conjunction with the various sections of the memory, as a result of which multi-user operation or multi-tasking operation is possible. Each of the sections of the memory can thus be used in the function of an accumulator. <IMAGE>

Abstract: Chromogenic substrates for the detection of hydrolyzing enzymes, processes for the preparation of these chromogenic substrates and the use of the chromogenic substrates. The quantification of hydrolyzing enzymes for diagnostic purposes has to date been carried out by determination of the amounts of a fluorescent or highly absorbent chromogenic dyestuff liberated in the hydrolytic reaction, detection of which has in part been possible exlusively by instruments or in the neutral to alkaline pH range. After enzymatic hydrolysis, the chromogenic substrates according to the invention lead to highly sensitive and specifically measurable signals regardless of the pH range. Azo dyestuff compounds with the general formula A-N=N-B (OR) in which A) and B) have the meanings given in claim 1 and R) is a radical which can be liberated by enzymatic hydrolysis, excluding a carbonyl radical, are provided. After enzymatic hydrolysis, highly sensitively and specifically measurable signals are obtained regardless of the pH range. The azo dystuff compounds mentioned are used for the detection of hydrolyzing enzymes, in particular glycosidases, phosphatases and sulfatases.
