Title: Signal derivation system for real=time evaluation of road surface profile under motor vehicle - has monitors for vertical deflections of wheels and with data reduction signal processing to classify profiles
Inventor: MUELLER ELMAR DIPL ING
IPC: B62D131/00
Filed: 1991-10-05
Abstract: Sensors on the wheel suspensions provide vertical deflection signals which are processed to monitor the suspension dynamics. The processed signals represent a real time profile of the road under the wheel and are compared with reference profiles to classify the signals i.e. data reduction. The classified signals are used to control the active suspension and other systems on the vehicle. The data reduction provides a simplified processing system operating in real time. A simple system monitors the frequency of amplitude peaks above a set level in each sampling period. The system allows active suspension control, improved steering etc. USE/ADVANTAGE - Simplified processing; real-time suspension correction. Dynamic control for regulating, control and monitoring systems, e.g. antilocking or antislip in cars and commercial vehicles.

Title: Flow density determination of radon gas passing from ground in to atmosphere - forming collection by placing container having base opening over ground surface and pumping through alpha particle measuring chamber
Inventor: GAST HEINZ DR RER NAT
IPC: G01T1/169
Filed: 1992-01-09
Abstract: The degree of opening of the edge (2) of the collection vessel (1) is defined by the ground surface region. The activity concn. of the radon in the collection container is determined at different times. The radon flow density is determined from the activity concn. values determined and the known surface content of the ground surface region. The gas is continuously pumped in a circuit contg. a filter (5) from the collection container (1), led through an alpha measuring chamber (6), and returned to the container. The determination of the radon flow density results based on the rise per unit time of the radon activity continuously running through the alpha measuring chamber of the gas flowing through the measurement chamber. ADVANTAGE - Time and labour cost for radon flow density determination is substantially reduced with improved measuring accuracy.

Title: IC engine recurrent process controller - includes event counter directly readable and writable by internal microprocessor with null comparator and interrupt logic
Inventor: FLAETGEN DIETMAR DIPL ING
IPC: F02D45/00
Filed: 1992-03-31
Abstract: The controller detects (16) signals from a crankshaft-mounted toothed wheel and switches them (15) to an edge detector (14) coupled to a down-counter (10) with a null comparator (11) and a buffer memory (12). When the count falls to zero a signal is sent to an interrupt flag byte register (21). The down-counter can be started or stopped (18) and the value stored in the buffer memory can be written into it by a latch register (19) with a single software trigger command. ADVANTAGE - Interrupt loading of controller is reduced significantly to minimise loss of precision of overall system due to problems of computation time.

Title: Method for detecting the actual tension value for the purpose of minimal-tension regulation in a multi-stand continuous rolling mill
Inventor: WAEHNELT HANS-DIETRICH DIPL IN
IPC: B21B37/52
Filed: 1993-06-07
Abstract: The invention relates to an expedient development of the method for detecting the actual tension value for the purpose of minimal-tension regulation in a hot-rolling mill as proposed in the main Patent Application P 4220121. In order to be able to take only instantaneous values for the load current detected in the tension-free state on the first stand as a basis for the formation of comparative values for minimal-tension regulation, the regulation of the first drive is controlled in such a way that, with the entry of the rolling stock into the second stand and following rapid rough compensation in the absence of synchronism between the two stands, regulation is then inhibited to avoid the influence of adjustment commands during the rolling out of cold areas in the stock. The method is suitable for tension- and compression-free rolling in continuous hot-rolling mills.
Patent DE-4320904-A1 (DE)
Title: Anti-lock control system
Inventor: POGGENBURG RUEDIGER DIPL ING
IPC: B60T8/72
Filed: 1993-06-24
Abstract: A description is given of an anti-lock control system which, when thresholds are reached by a wheel state variable, reduces pressure and hence initiates ABS control. As a preliminary to ABS control, a check is made to determine whether the wheel decelerations of the wheels of one axle due to braking fall below a threshold approximately at the same time. If this is the case, a change in the gradient of the pressure build-up is thereby initiated. <IMAGE>

Each control piston (18) bears at the end face on the said oscillating disc (8) and is connected by way of ports (19; 20) to ring passages (25; 26) in the timing cover (2) for admission and discharge of the hydraulic medium. Hydrostatic machines of the said type are preferably suited to the achievement of low-speed hydraulic motors with high torques according to Fig. 1. <IMAGE>
