Abstract: A non-dispersive infrared gas analyzer is disclosed that accurately measures the concentration levels of a plurality of gases within a gas mixture. The analyzer includes first and second sample cells and is utilized advantageously for the measurement of NOx and hydrocarbon gas present in the exhaust of an automobile engine. The gas mixture of the exhaust is chilled before entering the first sample cell to remove a substantial amount of the water vapor from that sample cell to facilitate measurement of the NOx gas. The second sample cell receives the gas mixtue in an unchilled state to allow for accurate measurement of the hydrocarbon gas. The analyzer includes processors which are utilized to further correct the NOx measurement and which also interact with each other to provide an output data stream that is representative of the concentration levels of the gases that are being analyzed.

Abstract: Système de réglage antiblocage où le glissement des roues sert de paramètre de réglage. La vitesse de référence requise pour produire le glissement est obtenue à l'aide d'une valeur de référence auxiliaire, qui indique l'accroissement de référence en cas de baisse soudaine de la vitesse des roues. Sinon, on tient compte de la vitesse de la roue qui occupe le second rang en termes de vitesse pour établir la valeur de référence en mode de réglage. En dehors du mode de réglage, c'est la valeur moyenne des roues avant qui détermine la vitesse de référence. On passe d'un mode de détermination de la vitesse de référence à l'autre - soit de la valeur moyenne à l'utilisation de l'accroissement de la valeur de référence auxiliaire et de la vitesse de la seconde roue en termes de vitesse - aussi bien au début du réglage qu'en l'absence de ce réglage, lorsque la somme des valeurs de tous les glissements de roue dépasse une valeur-limite (a).

Abstract: The invention is based on the object of developing a known rod- shaped radio antenna, which does not have an approximately circular omnidirectional characteristic when arranged obliquely, such that the antenna operates as an antenna with gain, with a largely circular characteristic, at an inclination angle deviating from the vertical by up to 40 DEG . 
<??>This object is achieved by an elastic rod (12) of dielectric material being fixedly connected to a spring element (11) and carrying a plurality of coils (SP1 ... SP4) and a radiating part (13). Together with the spring part (11), a first coil (SP1) which is electrically connected to the said spring part (11) has a first length L1 =  lambda /4. A second coil (SP2), connected to the first coil (SP1), has a length L2 =  lambda /4. A third coil (SP3) is wound running backwards from the end of the second coil (SP2) and has a length L3 =  lambda /8. A fourth coil (SP4) is wound from the end of the third coil (SP3) parallel to the second coil (SP2). A radiating part (13), having a length L4 = 3/8  lambda , is connected to the fourth coil (SP4). In this case,  lambda  is the mean operating wavelength of the relevant radio band. 
<??>A preferred area of application for the rod-shaped radio antenna is the Radio Network C of the German Federal Post Office. 
<??>The drawing shows a winding layout for the rod-shaped radio antenna.

Abstract: A method for forming a moving, continuous bed which is composed of granular and/or pulverulent flowable material and which is of constant thickness provides an improved uniformity of the bed by collecting material from a first moving bed so as to form a buffer stock, and by subsequently delivering material from the stock in a regular fashion so as to form a second moving bed which is continuous. An apparatus for carrying out this method comprises a belt capable of being passed through by said material. The material can be moved with the belt over a guide plate situated beneath the belt. In order to prevent too little material being present locally during brief interruptions in the supply of the flowable material and in order to prevent the material being compressed and pulverized in the event of an excessively large supply, a buffer is provided for the material, the discharge opening of which buffer is situated near and above the guide plate. The buffer has an overflow. The material is thus fed via the buffer onto the belt. Provided the buffer remains filled, it is capable of compensating automatically for fluctuations in the material supply.

Abstract: The invention relates to a method for the preparation of a supported procatalyst intended for the polymerization of olefins, in which particles are formed from magnesium halide and alcohol, the particles are reacted with an organometallic compound of any of the metals of the groups I to III, the thus obtained particulate product is activated by means of a titanium(IV) compound, and optionally a prepolymerization is carried out for the activated particles. A problem with this kind of a method is how to form particles from magnesium dihalide and alcohol having an advantageous structure for the polymerization of ethylene and particularly ethylene with a narrow molecular weight distribution. The problem has in the present invention been solved by forming the particles by spray-crystallizing a mixture of magnesium dihalide and alcohol to complex particles of magnesium dihalide and alcohol and by using titanium (IV) alkoxyhalide as the titanium compound. The catalytic properties of the particles thus obtained are improved, especially after the prepolymerization carried out by means of ethylene, which leads in the polymerization to a still more active, very hydrogen and comonomer sensitive procatalyst having a better molecular weight selectivity. The invention also relates to the specific use of the procatalyst prepared by such a method for the polymerization of alpha-olefins. By a procatalyst is meant in this context the catalyst component of the Ziegler-Natta-catalyst which is based on the transition metal and which before the polymerization is combined with the organometallic compound of aluminium or some other metal acting as cocatalyst

Abstract: The invention relates to intermediate-layer sensors having sensor elements (6,7) which are connected in parallel with respect to the forces and are installed in machine parts which transmit forces and torques. In the past, such sensor elements consisted, for example, of a plurality of discs and plates whose total height was different, which resulted in a different signal output of the sensor elements (6,7) for the same load. In addition, the numerous air gaps produced undesired pneumatic-spring effects. By reduction of the pneumatic-spring layers to a maximum of five, because of a reduction in the discs and plates, and by welding in the sensor elements (6,7), subject to high mechanical pretensioning in the covering discs (17,20) and looping over the sensor surface in order to achieve flatness, good accuracy and constancy of the degree of force shunting can be achieved. The shunt loading of the sensor elements can be varied by a vapour-deposited layer (27), which can be produced with good accuracy. The intermediate layer sensor is preferably annular or rectangular in shape. Load amplifiers (8) and further electronics modules (30) can be fitted in the central region and also in the circumferential region, and can be potted to form a cost-effective assembly unit. The signal lines (10) then no longer need to be highly insulated, as a result of which the quasi-random characteristics of the measuring system are improved. <IMAGE>

Abstract: An arrangement for controlling the tension in the saw-blading (5, 6) of a bandsaw equipped with an electrically controllable blading-tensioning arrangement by means of which the blading can be stretched so as to adjust the tension therein to a desired level. To this end, the arrangement includes automatically operating devices (8-13) which are operative to determine whether or not the blading-tension is optimal during a sawing operation. These devices are intended to sense and determine mutually different parameters, such as specific blading-tension, disturbances in the movement pattern of the blading, the linearity of the saw cut, etc. The arrangement also includes a microprocessor (9) which is operative to process the electric signals corresponding to the sensed parameters. The microprocessor is programmed to send control signals to the blading-tensioning arrangement when the microprocessor establishes deviations from limit values programmed therein with respect to the parameters or fluctuations of these parameters, thereby to adjust blading-tension in a manner to reduce these deviations or fluctuations. The invention also relates to a method for controlling the tension of sawblading.
