Abstract: A diesel fuel containing an additive, which improves soot burning, for reducing the pollutant emissions of the combustion exhaust gases of diesel engines by discontinuous burning-off of soot which has been deposited on the exhaust gas filter is described. For this purpose, a lithium salt, sodium salt or potassium salt of an aliphatic or aromatic alcohol, of a phenol, of an aliphatic acid or a naphthoic acid, of phenylacetic acid or of cinnamic acid, individually or as a mixture, is added to the diesel fuel before the latter is burned in the internal combustion engine. As a result of the addition of the alkali metal salts, the ignition temperature of the soot deposited in the particle filter is reduced and the soot is oxidised at a temperature which is considerably lower than the normal ignition temperature. The regeneration range for the particle filter is thereby much more frequently reached in real driving practice. As a result, a critical filter loading with soot, which can cause filter damage on burning-off, is avoided. A further advantage of the process described is that, according to present knowledge, no additional substances injurious to health are emitted during running as a result of the addition of these alkali metal salts to the diesel fuel. <IMAGE>

Abstract: 5n7 According to the present invention, an observing machine is set at an observing point and collimation targets are disposed at three fixed points. By collimating the three fixed points from the observing machine, horizontal angles and height angles of three types are measured, respectively, and equations of error about the horizontal angles, height angles, distances between the three fixed points and straightnesses between the fixed points are established from these observed data. First, approximate values are obtained from the observed data, and further, by utilizing the method of least squares, the positions of the respective points can be obtained in details. Furthermore, by collimating the three fixed points and points to be sought from the observing machine, the horizontal angles and the height angles of three types are measured, respectively, so that the positions of the points can be obtained in details. Further, by forming three targets on a subtense bar at predetermined distances, at least the positions of the points can be obtained from the observation of the distances between the three points. Furthermore, by setting the observing machine at a known observing point and by positioning a measuring portion specified by the three fixed points at the point to be sought, collimation targets can be disposed at the three fixed points. By collimating the three fixed points from the observing machine, the positions of the three fixed points can be obtained in details. Further, by forming a measuring end portion at the forward end portion of a reference scale, a position of the measuring point can be obtained even when the measuring point cannot be directly observed from the outside. Furthermore, since a plurality of targets are formed of photoconductive optical material such that the internal light is emitted as a diffused flux of light, collimation can be easily performed even in a relatively dark place.

Abstract: Bande révélant une ouverture frauduleuse destinée à être utilisée sur un récipient. Le brevet U.S. No 4.876.123 a trait à une bande révélant une ouverture frauduleuse destinée à fixer une première partie d'un récipient à une seconde partie d'un récipient pour fermer une ouverture du récipient. La bande comprend un film monocouche transmetteur de lumière possédant une première et une deuxième surface principale opposées. Pour préparer la bande, il est nécessaire d'imprimer les indices en couleur de la première surface et les indices en couleur de la deuxième surface de manière que les indices s'opacifient en l'absence d'ouverture frauduleuse. Cette nécessité pose problème car il faut une inscription parfaite et une bonne adaptation des couleurs de l'encre des indices et du colorant ou du pigment de l'adhésif. La présente invention a trait à une bande (10) révélant une ouverture frauduleuse comprenant un film (12) monocouche transmetteur de lumière possédant une première et une deuxième surface principale opposées (20, 24). Sur chaque surface des indices en couleur (22, 26), de préférence identiques, sont imprimés de manière que les indices en couleur sur chaque surface opacifient les indices en couleur de la surface opposée quand le film n'a pas été séparé intérieurement, mais aucun des indices n'opacifie un autre indice quand le film a été séparé intérieurement. La configuration d'impression de la présente invention n'exige plus une concordance précise entre les indices en couleur de la première et de la deuxième surface, et n'exige plus une adaptation des couleurs de l'encre et de l'adhésif.

Abstract: The workpiece charges are transported stepwise through the throughflow furnace lying on movable floor elements (12), and at each step they are individually lifted from below, beginning at the outlet side end (9) of the throughflow furnace, and displaced by one step. In this manner, even extremely heavy workpiece charges, such as coils, can be heat-treated in a throughflow furnace. Transport is effected by a transfer machine (13) which can travel in the longitudinal direction of the furnace, beneath the furnace floor (14) in a space (15) under the furnace, and which can engage through the furnace floor (14) with a lifting device (18). For this purpose the furnace floor has two apertures (20,21) running in the longitudinal direction of the furnace. The movable floor elements (12) form a closed upper floor which covers the apertures (20,21) of the furnace floor. The space (15) under the furnace is thus thermally insulated. <IMAGE>

Abstract: A method of forming complex polyimide foam shapes by impregnating a low density, open cell, reticulated foam with polyimide foam precursor, placing the combination in a mold, closing the mold, then heating the assembly to the foaming and curing temperatures of the precursor. As the powdered precursor expands, it spreads throughout the reticulated foam producing a product having substantially uniform density and polyimide foam characteristics. If desired, the reticulated foam can be removed from the product by using a material that outgasses and boils away at polyimide processing temperatures. Radar absorbing materials may be incorporated in the reticulated foam so that the final product will have uniformly distributed radar absorbing components with the desirable high temperature resistance and other properties of polyimide foams.
