Abstract: A method and apparatus for coating both faces of a moving web, such as a paper web, in which the web is fed longitudinally at a speed in excess of 300 meters per minute, between a rotating support roller and a blade, the blade having a bevel at the point of contact with the web. Coating material is fed into the nip between the roller and the web to coat the paper web on both faces. The angle which the blade forms with is chosen to be not greater than 20.degree. and the bevel width, as measured in the direction of movement of the web, is at most 0.15 centimeters. Preferably the blade is urged against the web with a force not exceeding 0.20 kgf per centimeter width of web.

Abstract: A method of and device for making rods, tubes and profiled articles directly from a melt, especially metallic melt, by extrusion pressing by means of a forming tool and die. The melt charged into a receiving compartment of the device in successive batches is cooled so as to be transformed into a thermal-plastic condition. There is a build up layer by layer to form a bar and alternately with the charging of the receiving compartment the bar stepwise is subjected to pressure to extrude a portion of a strand.

Abstract: A method and apparatus for coating both faces of a moving web, such as a paper web in which the web is fed longitudinally at a speed in excess of 200 meters per minute and a coating material is applied to each face of the web, and is smoothed out by means of two blades, one on each face of the web. The blades are formed with a bevel at the point of contact with the web, the width of this bevel measured in the direction of movement of the web is at most 0.08 centimeters and the angle of the blade with respect to the web is less than 25.degree.. Preferably the blades are urged against the web with a force not exceeding 0.20 kgf. per centimeter width of web.

Abstract: In a hydrostatic bearing there is provided in known manner pairs of balancing pockets between the coacting bearing surfaces. To counteract the bearing load the pockets of each pair is fed with pressure fluid through a new combined throttle valve which not only distributes the flow of pressure fluid but also its throttling or constricting effect between the pockets of the pair. The valve contains a freely movable roller element cooperating with two pairs of diametrically opposed ports in the valve housing, the ports of one pair individually communicating with each its pocket of the pair of pockets, the ports of the second pair communicating with a pressure source or pump and a low pressure outlet or sump, respectively.
