Abstract: L'invention concerne un mode d'exécution préférentiel du procédé et un appareil pour recycler les pneumatiques usagés de voitures , consistant à introduire progressivement des petits morceaux de pneumatiques dans un réacteur vertical du type à contre-courant dans lequel le matériau descend progressivement dans le réacteur alors que des gaz produits dans ce dernier traversent en remontant le matériau qui effectue une descente vers le bas du réacteur, pour décomposer et volatiliser le matériau du type caoutchouc. Au niveau de la partie inférieure de la cuve, un gaz porteur d'oxygène est injecté dans le réacteur afin de brûler une partie du carbone du caoutchouc et pour produire des gaz de combustion brûlants qui remontent verticalement pour décomposer de manière pyrolytique les morceaux de caoutchouc et pour volatiliser ce type de matériau. La quantité d'oxygène est régulée par une insuffisance d'oxygène pour maintenir la température de la zone de combustion à une température inférieure à 500 °F. Les gaz ainsi que les matériaux en caoutchouc et les huiles volatilisées sont éliminés du réacteur, à une température voisine de 350 °F, au niveau d'une hauteur inférieure à la couche supérieure des morceaux de caoutchouc, dans un courant très rapide, afin de maintenir les huiles entraînées dans l'écoulement d'air. Ledit écoulement d'air est dirigé dans des condenseurs afin de condenser les huiles issues du traitement du caoutchouc. Les huiles brutes issues du traitement du caoutchouc sont ensuite classifiées pour obtenir un matériau résiduel d'huile de caoutchouc à fractions lourdes ayant un point d'inflammation supérieur à 340 °F et supérieur dans une atmosphère prédéterminée, et un point d'ébullition supérieur à 450 °F à 20 mm Hg, ledit matériau résiduel pouvant être utilisé comme agent diluant/plastifiant dans la composition de caoutchouc, cet agent ayant donné des résultats inhabituels et inattendus. Le gaz porteur d'oxygène est maintenu au départ à une température comprise entre 40° et 60 °F, puis il traverse le

Abstract: The application relates to a method for the production of shaped parts by force- or pressure-influenced forming processes by regulating the forming process. In particular, the application relates to the production of deep-drawn sheets for motor-vehicle bodywork. The aim here is to make it possible to produce the shaped parts virtually without defects in a relatively simple manner by regulating the forming process. For this purpose, the movement of the starting material (1) for the forming process and/or its time derivatives is measured during the forming process and is adjusted by means of the applied force or the applied pressure in such a way that the movement of the shaped part and/or its time derivatives corresponds to the movement of the shaped part and/or its time derivatives in the case of a forming process which produces an acceptable part, irrespective of any disturbance variables acting. The speed of the starting material (1) during the forming process can either be measured directly or determined via correlative measurements of the texture of the material at various points. <IMAGE>

Abstract: A method and apparatus are provided for photoelectrochemical reproduction of an image on a plate or roller. For a printing press, the apparatus includes a reusable image roller coated with a oxide semiconductor. A plating solution is applied to the image roller as a thin film. The desired image is written onto the oxide semiconductor by light illumination that generates a photoelectrochemical reaction between the semiconductor and the plating solution. In a preferred embodiment, the image roller is coated with hydrophilic p-type NiO. The image is written onto the roller as dots of oleophilic metallic copper, which are formed on the NiO coating by laser-generated cathodic photoelectrodeposition. Subsequent erasure of the metallic copper image can be accomplished by chemical or electrochemical dissolution of the deposited copper. The method functions to create, erase, and recreate high-resolution images directly on a printing press roller without the necessity of precise matrix registration.

Abstract: The rotating shaft of a motor has the surface layer of the journal only thereof formed of hard nitride. Thus, the shaft is lower in price, lighter, and more durable than those composed of hard material throughout. A method of this invention applies fluoridization to the shaft prior to nitridation. In this way, a passive film such as oxidized film on the surface of the journal turns into a fluoridized film to protect said surface. Accordingly, even after the lapse of time from formation of a fluoridized film to nitridation, the fluoridized film formed on the surface of said journal protects said surface in favorable condition and prevents an oxidized film from being formed again on said surface.
