Patent DE-3705983-A1 (DE)
Title: Device for monitoring the utilisation factor of the coefficient of road friction prevailing in the braking and/or acceleration of a motor vehicle
Inventor: VOELCKERS JUERGEN
IPC: B60T8/1763
Filed: 1987-02-25
Abstract: The slip characteristic curves for various, especially typical road conditions are stored in the memory units of a digital circuit module. In the processing units of this digital circuit module, the instantaneous wheel slip SR of the wheels is continuously calculated from speed and acceleration input signals supplied by sensors and a function SR = f(bF) is formed according to the vehicle acceleration bF, and the characteristic curve approximating closest to this function is then determined from the slip characteristic curves stored in the memory units, and the ratio (<b>Fmax)/<b>Nmax is then formed between the highest acceleration value bFmax detected and the highest acceleration value bNmax of the determined characteristic curve. <IMAGE>

Title: Method and apparatus for determining the degree of compaction during the compaction of a substrate by means of a vibrating roller
Inventor: BOEHM ALFRED
IPC: E02D1/02
Filed: 1987-03-10
Abstract: The invention relates to a method and an apparatus for testing the degree of compaction during the compaction of a substrate by means of a vibrating roller having at least one vibrating binding, there being derived from the vibrational movement of the binding a signal which essentially represents the vertical acceleration component of the vibrational movement. In order to allow a frequency-independent, exact and simple measurement of the degree of vibration during the compaction of a substrate by means of a vibrating roller, the signal is processed to form an alternating-voltage signal cleared of construction-related characteristic-oscillation components of the binding or vibrating roller. The alternating-voltage signal is converted into a direct-voltage signal and, during predetermined time segments, is integrated against an oscillation half-wave of the direct-voltage signal. At the same time, the increase in the integration voltages obtained, which are proportional to the increase in the degree of compaction, is used as a measure of the compaction of the substrate.

Title: Liquid-cooled cylinder head
Inventor: RUF MAX
IPC: F02B1/04
Filed: 1987-03-31
Abstract: A liquid-cooled cylinder head for a multi-cylinder internal combustion engine has, for each combustion chamber (2), a cooling liquid chamber (3) which is penetrated by a spark plug head (4). The individual cooling water chambers (3) are connected via risers (7) to a discharge collecting passage (8) which extends over the entire length of the cylinder head. The heads (4) are penetrated by cavities (5) which impinge upon the collecting passage (8). As a result, a one-piece core can be used during manufacture to cast the collecting passage (8) and all the spark plug cavities (5) in the cylinder head. The cavities (5) are separated from the collecting passage (8) by means of a pressed-in sleeve (9). <IMAGE>

Title: Method for breaking down aggregated organic and mineral constituents in suspensions, such as sludges and wastewaters, and apparatus for carrying out the method
Inventor: KUPCZIK GUENTER DIPL ING
IPC: B01D21/00
Filed: 1987-06-11
Abstract: To break down aggregated organic and mineral constituents in suspensions, such as sludges or wastewaters (effluents), these are subjected to turbulence in the treatment pass. In this case the sludges or wastewaters are exposed to a cavitation condition. As a result, a three-phase flow is produced in which the aggregated constituents are broken down into an organic and mineral phase. The apparatus provided therefor has a centrifugal pump (1) in the form of a vortex separator in the design as a rotor (11) which has radially orientated blades on a hub (19). For the blades (20) of the centrifugal pump (1) there is provided a drive (10) which has a speed which forms a cavitation downstream of the blades with respect to the direction of motion of the blades. <IMAGE>
Patent DE-3721279-A1 (DE)
Title: Digital storage of information, particularly traffic radio announcements in broadcast receivers
Inventor: BURKHARDT STEFAN DIPL ING
IPC: G08G1/09
Filed: 1987-06-27
Abstract: The methods described above are particularly suitable for recording traffic radio announcements in car radios. When travelling by car, it is frequently not possible to catch all necessary details of a message because of the variety of messages, the distraction by the traffic and the driving noises. A recording unit which stores the last traffic radio announcement in each case received and repeats it as many times as desired provides for much better utilisation of the existing traffic radio system. Similarly, it is useful, as described above, to define a search mode with the device switched off, in which, in order to save electrical energy, individual units of the receiver (compare 3.2) or even of the entire receiving section (compare 4) are temporarily switched off. This is possible since traffic radio transmissions are only transmitted approximately every 30 minutes. However, this ensures that the latest traffic message is in each case stored and thus is also directly available when the trip is started. To ensure the operation of the system, the car radio must have a conventional circuit for evaluating the programme identification which makes it possible to detect a traffic radio station as such automatically and to select it. Since traffic radio announcements only have a length of a few seconds or, at the most, a few minutes, a conversion of the analogue voice signal supplied by the receiver into pulse modulation and subsequent digital ...

Title: Method for monitoring the interior spaces of buildings by detecting pressure fluctuations, and a sensor and signalling device for carrying out such a method
Inventor: SCHAAF NORBERT DIPL ING
IPC: G08B13/20
Filed: 1987-09-19
Abstract: A description is given of a method which can be used to render interior space monitoring devices, which react to fluctuations in air pressure, insensitive to disturbances which are caused by pressure waves acting on the building from outside. For this purpose, a supplementary external sensor (12) is provided outside (14) the building (8) in addition to the pressure sensor (10) arranged in the interior space (6). The outside influences are eliminated in that an enable signal is generated when only the interior sensor alone detects a signal which is characteristic of an event, but not simultaneously the external sensor. The signals can be logically combined by forming the difference or by negatively feeding back the external signal to the internal signal. Irrespective thereof, the internal signal can still be examined in an evaluation unit for the presence of specific characteristics, so that a message is finally triggered by a logic gate only when both the evaluation unit and the logic unit or a switching stage which is connected downstream simultaneously emit an enable signal. A description is also given of a novel sensor for detecting the signals. <IMAGE>

Patent DE-3816377-A1 (DE)
Inventor: FORTH ROBERT DIPL ING
IPC: H04Q7/06
Filed: 1988-05-13
Abstract: For own position-fixing, the delay time-differential measurements running in the organisation channel of a network-synchronous cellular mobile radio network are used for cell boundary detection. For this purpose, in the simplest case a reception unit 1 for the organisation channel, a device for the delay time-differential measurement 2 and a working memory 3 are necessary. These three units are also components of a conventional mobile station. Also necessary are a read-only memory 4 with the location coordinates of all fixed radio stations and a computing unit 5 for connecting the delay time-measurements to the location coordinates and calculating the own position according to the hyperbolic position-fixing method. The display can be a LCD display 6 or a graphic display 7 in conjunction with a suitable data bank 8. As an addition to a mobile station 11, the location coordinates can be transmitted back to an authorised subscriber, even of a dedicated circuit network on a request from it (Fig. 2). <IMAGE>

Patent DE-3833560-A1 (DE)
Title: Pump arrangement
Inventor: LISKA GEORG
IPC: F04B1/053
Filed: 1988-10-03
Abstract: A double pump consists, for example, of a single-cylinder and a six-cylinder radial piston pump (2 and 3, respectively). A driveshaft (6) fitted in a housing bore (4) bears, for both pumps, a common eccentric (5). The eccentric (5) rotates in an eccentric space (10), into which plunge delivery pistons (7 and 8, respectively) of the pumps (2 and 3) for drawing in pressure oil. In order that the two pumps (2 and 3) do not influence each other on the inlet side due to pressure fluctuations, the housing bore (4) has a shoulder (28). The shoulder (28) divides the eccentric space (10) into a large and a small chamber (10A and 10B, respectively). An inlet connection opens into the larger chamber (10A). The shoulder (28) has the effect of a throttling bore, so that the pressure oil flows from the larger chamber (10A) gently into the smaller chamber (10B). In this way, pressure fluctuations can be reduced already on the inlet side, which fluctuations would hinder uniform filling of the delivery pistons (8) of the pump (3). <IMAGE>
