Abstract: New tungsten carbides alloyed with fluorine in amounts up to 0.5 wt% and possibly with fluorocarbon compositions are described. It is possible to produce them by means of a new process of chemical vapour deposition, in which tungsten hexafluoride, hydrogen and a carbon-containing gas are used. A specific feature of the new process is the preliminary thermal activation of the carbon-containing gas.  The tungsten carbide coatings are deposited on construction materials and items made from them. They possess enhanced resistance to wear, corrosion and chemicals.

Abstract: On fabrique une feuille de tissu en utilisant une presse humide modifiée dans un processus de pressage humide modifié par presse pneumatique étanche intégrée. Après une formation initiale et un assèchement par aspiration conventionnel, la bande se conforme au profil de la surface d'une toile relativement grossière de façon à donner à cette bande une surface texturée. En créant un différentiel de pression à travers la bande d'au moins 30 pouces de mercure et un courant d'air à travers la bande d'au moins 500 SCFM/in?2¿, la presse pneumatique assèche la bande humide sans compression à une consistance comprise entre environ 30 % et 40 % avant un tambour de séchage chauffé. Cette bande est asséchée de façon à sensiblement préserver sa texture tridimensionnelle du type séché à coeur. Ce processus permet d'obtenir une bande présentant une capacité hydrophile et un volume de haute qualité qu'on n'attend pas d'un produit fabriqué par pressage humide.

Granted: 2007-08-28
Abstract: In known large round balers, a rotating side wall is provided that can be pivoted away from a baling chamber either in a straight line or about a pivot axis, so that the pressure on the end faces of the cylindrical bale is reduced during the unloading process. A large round baler is proposed in which a support structure provided with rolls for supporting one or more flexible bale-forming elements, which can be pivoted about a pivot axle that penetrates the side walls of the baling chamber. At least one side wall is provided with a cam having an inclined surface which is ramped outwardly from the side wall from top to bottom. The support structure is provided with a cam follower that can slide on the surface cam so as to move from bottom to top when the support structure is raised to effect a discharge of a formed bale. The cam is maintained in engagement with the follower, which travels in a vertical plane, due to outward deflection of the side wall, which results in a decrease of the force applied by the side wall on the bale and the frictional force resisting movement of the bale relative to the wall so as to aid in the discharge of the formed bale from the baling chamber.
