Abstract: Ledit système consiste à évaluer le mu(K) à un moment donné et la pente Kmu de la courbe de patinage mu à partir du couple d'entraînement ou du couple de freinage transmis et à partir de la vitesse des roues. Les valeurs obtenues pour Kmu par des calculs successifs constituent la valeur effective du régulateur, que l'on compare avec une valeur exigée Kmu. La variable réglante ainsi obtenue influence un organe final qui fait varier la pression de freinage ou, par exemple, la quantité de carburant par unité de temps. Le gain de l'organe final varie en fonction du coefficient d'adhésion $g(m)(K) obtenu. L'invention est complétée par des propositions concrètes.

Abstract: A process for purifying a nitrogen trifluoride gas according to the invention comprises heating a NF₃ gas containing N₂F₂ as an impurity to a specific temperature in a vessel lined with a tough passivated nickel fluoride coating. This process enables the removal of N₂F₂ gas at a high rate with a small loss of NF₃. Thus, a high-purity NF₃ gas favorable as a starting material for a dry etching agent for semiconductors can be obtained with ease and safety by again purifying the NF₃ gas, which has been purified by this process, using a known adsorbent.

Abstract: During the feed of cartridges (16) to a gun (11) moveable in elevation from a fixed cartridge magazine (14), it is customary to use a deflecting device, by means of which the cartridges (16) can be fed reliably to the gun (11) in any position of the latter. According to the invention, the cartridges (16) are fed to the gun (11) in the telescopic guide channel (20). At a high elevation of the gun (11), this guide channel (20) is pushed together; at a low elevation of the gun (11), the guide channel (20) is extended. Arranged in the guide channel (20) is a bucket chain (17) for transporting the cartridges (16). The individual buckets (21) of this bucket chain (17) are connected to one another via toggle joints (22-24), so that the bucket chain (17) too can be drawn apart and pushed together in conjunction with the guide channel (20). One end of this guide channel (20) is fastened to the cartridge magazine (14) and the other end is fastened to the gun (11). The drive of the bucket chain (17) takes place at both ends of the guide channel (20) and, because the bucket chain (17) is of variable length, does not have to be carried out synchronously.

Abstract: A fuel injection pump for internal combustion engines has a pump piston (12) defining a pump working chamber (15), which piston can be driven by way of a cam mechanism (14) in a reciprocating and at the same time rotational movement, during its intake stroke filling the pump working chamber (15) with fuel by way of an inlet (42), which it controls as a function of the angle of rotation. An injection timing device (30), as a function of the speed, rotates the position of the lifting curve of the pump piston (12) relative to its rotational postion to "advance" in the case of high speed and "retard" in that of falling speed. In order to enlarge the injection timing range without varying the cam geometry and/or to increase the cam length without varying the injection timing range, a non-return valve (43) with closing direction towards the inlet (42) is arranged between the inlet (42) and the pump working chamber (15) and the control of the inlet (42) by the pump piston (12) is so designed that, when its lifting curve is in the advance postion, the pump piston (12) does not close the inlet (42) until it is inside the rising edge. <IMAGE>

Abstract: A combination of raw coal and water is introduced as a slurry (23) into a vessel (12). Chemicals are introduced at a feed inlet. The mixture is reduced by interaction with a bed of agitated (15,16) grinding balls (14). Air is introduced into the lower portion of the vessel and forced upwardly through the circuitous passages among and between the grinding balls. The rising air bubbles carry the more hydrophobic product upwardly into a froth compartment (34) of the vessel (12) and through a discharge outlet (36) of the vessel. Wash water (37) is introduced into the upper portion of the vessel and descends through the froth and the ball passages carrying entrained and less hydrophobic particles into the grinding chamber (40). The non-floatable material flows downwardly from the grinding chamber (40) to a refuse zone (42) for discharge (45) as refuse from the vessel.
