Abstract: Piezoelectric firing device for an electronic switch (10) with galvanic decoupling of the input control electronics (9) and the electronic switch (10) having a small plate of piezoceramic material with electrode pairs (13,13',14,14') as an input electrode pair (13,13') and at least one output electrode pair (14,14') and, if required, with a feedback electrode. The input electrode pair (13,13') of the small plate receives from the input control electronics (9) a trigger firing pulse which is, in particular, a pulsed a.c. voltage. The frequency of this a.c. voltage and the resonant frequency of a preferred oscillation mode of the small plate are matched to one another with better than two digit rotational symmetry. The effective surfaces of the input electrode pair (13,13') and the output electrode pair (14,14') are essentially of equal size so that there is preferably a 1:1 signal transmission from the input electrode pair (13,13') to the output electrode pair (14,14'). A feedback electrode, which is preferably provided, is preferably provided in the region of an oscillation node line of the mechanical stress of the next higher radial oscillation mode. <IMAGE>

Abstract: Eine Kabelverschraubung 10 besteht aus einer Schraubhülse 12, einer auf dieser verschraubbaren Klemmmutter 14, einem Dichtkörper 16 in der Klemmutter und einer Gleithülse 18 zwischen Dichtkörper und Klemmutter. Zwischen Dichtkörper 16 und Klemmutter wird mit Ausnahme eines Kontaktes im Klemmuttermund keine solche Berührungszone gebildet, die beim Verschrauben der Klemmutter ein Mitdrehen des Dichtkörpers bewirken könnte. Am Klemmuttermund wirkt die Reibkraft am geringsten Radius, weswegen das Mitnahmemoment klein genug bleibt. Die Kabelverschraubung kann von Hand leicht verschraubt werden. Sie gewährleistet Gasdichtigkeit und eine hochwirksame, aber dennoch höchst schonende mechanische Zugentlastung und darüber hinaus einen absoluten Knickschutz für das Kabel im Klemmuttermund.

Abstract: In a method of and a device for removing paint coats, for separating compound materials and for stripping, the workpieces which are embrittled by a liquefied gas with a low boiling temperature and are elastic at room temperature are subjected to a violent oscillating movement in an oscillating container (2). In order also to be able to process heavy workpieces, a compensation mass (10) is provided which oscillates counter to the direction of movement of the oscillating container. In addition, oscillating container and compensation mass move horizontally. The drive can occur by means of a crank drive (4) with two crank arms (7, 8) lying opposite one another. For very high maximum speeds of the container, the drive occurs preferably by means of a linear drive. <IMAGE>

Abstract: Phosphate coatings are formed on metal surfaces e.g. sheet steel by use of a zinc phosphate composition having a low ratio Zn:P2O5 but containing relatively high contacts of CIO3 and NO3. The process results in coatings having a fine grain and high wet corrosion resistance and which are particularly suitable for immersion electro-lacquering. Solutions contain (in g/l) 0.3-1.3 Zn, 10-26 P2O5, 0.1-3 Ni, 1-6 CIO3 and 5-25 NO3. The ratio of P2O5/Zn is in the range 9-85 and the ratio of Ni/Zn in the range 0-1.5. Solutions may also include sodium nitrite or nitrobenzene sulphonate, BF<->4 or SiF<2->6 and small amounts (e.g. up to 0.5 g/l) of other cations e.g. NH<+>4, Ca, Mn, Cu, Co.

Abstract: The flywheel has four upper (1) and four lower (1a) moving mass elements which set themselves between a minimum and maximum distance from the centre of rotation (3), under the influence of centrifugal force. In this way, the moment of inertia of the flywheel masses also varies between a minimum and a maximum value. In known flywheel masses, the moment of inertia is constant and determines the magnitude of the drive torque required. On the other hand, the proposed flywheel has to overcome only a reduced moment of inertia - on starting or accelerating from a reduced speed - so that now a reduced drive torque is adequate. On the other hand, in the case of the said drive torque, a greater storage capacity can be achieved in the end effect. The method and the flywheel can be used primarily in electrical drives, especially with a battery or accumulator. <IMAGE>

Abstract: Dans un toit de bateau deployable, formant de preference une partie integrante d'un radeau de sauvetage gonflable, un dispositif de reperage passif est constitue par un reflecteur de localisation pliable qui est mis en position en meme temps que le corps du toit lors du deploiement de ce dernier. A cet effet, jusqu'ici on placait sur le toit un miroir triple dont les aretes exterieures sont pourvues de tuyaux qui sont aussi remplis lors du gonflage du radeau et assurent ainsi le deploiement du reflecteur. Il en resulte le probleme que le reflecteur, en raison de son poids, deplace la charge du radeau vers le haut et que lors de la destruction des tuyaux de deploiement du miroir, le dispositif de reperage est mis hors service. Le but de l'invention est donc de fournir un dispositif de reperage qui ne presente pas de parties facilement endommageables et qui reduit la charge si tuee en haut. A cet effet, des elements en forme de barres (15, 16) sont disposes le long des aretes des surfaces de reflexion (12, 13), ces elements etant relies d'une part au corps du toit (10) et d'autre part entre eux, a la maniere d'une carcasse de parapluie, au point central (14) du reflecteur (11) de maniere a pouvoir s'ecarter les uns des autres.

Abstract: Heavy hydrocarbonaceous materials are converted to distillate products and pitch in a hydrogen donor diluent cracking process, and the pitch is utilized as feed to a delayed coker. Green coke is calcined in a vertical shaft kiln, and steam is injected into the bottom of the kiln to produce hydrogen by reaction of steam with coke. The hydrogen is drawn from the kiln and used to hydrogenate recycle donor solvent for the cracking step. High sulfur coke can be desulfurized in the kiln, and distillate products in addition to donor solvent can be hydrotreated using hydrogen from the kiln.
