Abstract: Method for leak detection in a pipeline system, more particularly in a water supply and sewer system. The purpose of the invention is to efficiently and with great accuracy determine the scope and location of damages in the line system. For this purpose leakage indicating means are employed that comprise tracers, which are supplied to the water running through the pipes, each pipe being supplied a special tracer. Samples are taken at certain points downstream in the system. These samples are analysed and the concentration of tracers is determined. Using the concentration figures, the inflow of tracers from adjacent pipes can be established, in respective pipes. Thus, an estimation of the leakage from and to each pipe can be made.

Abstract: The alarms are connected via the central control electrical unit to a time calculator or clock. By a key impulses can be transmitted to the central unit which partly emits impulses for starting the time calculation, and partly for an opening lock motor. The alarms are released when the time calculation reaches a predetermined point, but the calculation is interrupted when a logical process is executed manually, e.g. the opening of a door or the removal of the key. When the seal of the display unit is closed, the central unit emits a start impulse to the time calculation. - Sealing of the locked display unit comprises a closed electromagnetic circuit which is broken when a door is opened, causing the central unit to react. The circuit is composed of one or more fibres through which electromagnet waves can be transmitted.

Abstract: A motion-damping apparatus is proposed which has a shock absorber disposed between a vehicle axle and a vehicle body. A piston that is supported on the vehicle body via a piston rod is movably supported in an inner jacket tube of the shock absorber. The piston divides work chambers filled with an electrorheological fluid as a damping fluid. The work chambers communicate with one another via an overflow cross section, the size of which is defined by a control slide the position of which is determined by an axially movable sheath. The sheath forms a first electrode, while the walls of an annular conduit receiving the sheath form a second electrode. The intensity of an electrostatic field that can be developed between the electrodes has an influence on the magnitude of the shear stress of the damping fluid flowing in the annular conduit and hence on the deflection of the sheath. In this way, the damping of the shock absorber can be adjusted via the electrostatic field present at the electrodes.

Abstract: To secure a vehicle, a movable lock device (11,12) engages a component rotatably connected to the vehicle crankshaft (5), e.g. the flywheel (2), and is moved to its locked position by a spring (14). An electrical power source (15) moves the lock device to its freed position, and is in turn activated by a code card or key activating a control part. A security device blocks the electrical power source irreversibly on receipt of signals not determined by the code card or key, and the control part. - The security device is positioned so that the blocking effect on the electrical power source can only be cancelled by workshop intervention, and incorporates a switch fitted inside the lock device housing (10). A control signal transmitted by the control part to the lock device has lower voltage than that of the vehicle battery/generator. The signal is an AC voltage or a pulsating DC voltage, and is superimposed on that of the vehicle battery/generator. (Provisional basic advised week 89/49)(1/2)

Abstract: A method for dividing a frame structure for a mobile telephone system which operates in half-duplex, i.e. in which the transmission and reception of signals in a mobile takes place within mutually separate time-slots (TS0 and TM0 respectively). Each frame includes three time-slots, each intended for transmission and reception. According to the method, the frame structure is divided so that transmission (TX) first takes place in a transmission time-slot (TS0). Reception (RX) then takes places in a reception time-slot (TM0) which is separate from the transmission time-slot (TS0). Subsequent to reception (RX), the frame structure includes an idle time (t1) which remains until further transmission (TX) takes place in the next-following frame. The method enables the frequency synthesizer (FM) of the mobile in the reception direction to be set to a channel (fx) different to the reception channel (fm) and then to be reset accurately to the reception channel (fm).

Abstract: The parameters detected are the ion current maximum value and its position, the area under the ion current curve, the position of the centre of gravity and the derivative maximum value and its position. The parameters are used for determining the engine load, temperature and combustion quality. - The position of the centre of gravity corresponds to the angle position where the area under the on current gives the same large torque around the top dead centre as the sum of the ion current curve part torques. Combustion quality, with regard to small exhaust gas emissions, is determined mainly with the aid of the curve area and by reducing the fuel amount until the engine temperature commences to rise rapidly. The parameters are determined after suitable signal processing, such as filtering and calculating.
