Abstract: A pressing method and apparatus for dewatering a fibre web, such as a paper or cardboard web, in a paper machine press section including two press rolls through which the web is conducted carried on either a single fabric or interposed between a pair of fabrics. The web is pre-pressed in a pre-pressing zone located in the throat region between the press rolls. The pre-pressing pressure is applied to the web through the mediation of a substantially impermeable band which passes through the press nip in overlying relationship with the web as the latter is conducted over a sector of one of the press rolls. After the pre-pressing step, the web is immediately conducted through the zone of the press nip, the pressing of the web which takes place in the press nip determining the dry matter content of the web subsequent thereto. The pre-pressing zone immediately precedes the zone of the press nip so that the pre-pressing and nip zones together in combination constitute a pressing zone. The peak pressing pressure present in the press nip zone is greater than the pressure in the preceding pre-pressing zone.

Abstract: The invention relates to a method of producing a reproduction of an object and an apparatus for carrying out said method. A particular object of the invention is the reproduction of the remaining stump of an amputated leg (18) for producing an improved prosthetic socket. When carrying out the method, the object (18) is positioned in a predetermined position in relation to a rotatable framework (8) on which a laser apparatus (12) and a video camera (13) are mounted in such positions that they can illuminate, and pick up, respectively, the image of a contour line (17) of the object via a pair of mirrors (15, 16; 20, 21) each during the rotation of the framework (8) through substantially a complete revolution. The image thus obtained of the contour line (17) is converted through a video/AD-converter (26) into numerical information identifying coordinates of points on the line. This information is supplied together with measuring and control programs to a computer (27), the output signals of which are supplied as input signals to a control electronic unit. The output signals from the electronic units control a model milling cutter in such a way that this on a workpiece produces a contour line which corresponds to a modified form of the contour lines of the object. The framework (8) with laser apparatus (12) and video camera (13) is intermittently rotated stepwise a predetermined fraction of a revolution, and for each step the abovementioned measures are repeated until the framework has been rotated through a complete revolution.

Abstract: A hydraulic valve constructed as a multi-way valve with pressure medium feed through the valve in two parallel ducts. Closing and opening of ports 1, 2, 3, 4, T to the various ducts is performed by a combined piston/slide 6. The piston 6 is provided with cams 7, 8, 9 which, in interaction with throttling edges A, B, C, D, E inside the valve space, where the piston 6 runs, open or close the ducts and connections to the valve. Operation of the piston 6 is brought about by applying a control pressure at one end of the piston, where the piston is provided with a pressure area. The control pressure can be produced in any way. At the opposite end of the piston, the piston bears against a valve seat F when control pressure is applied to the piston. This valve seat seals effectively between a duct inside the valve seat and a port outside. At the same end of the piston, there is also a return spring 10 which returns the piston to the starting position when control pressure is not applied to the piston. The object of the valve is to produce a valve in which two ducts through the valve are fed in parallel with pressure medium in separate ducts with the same pressure in the two ducts and in which one of the outputs from the two ducts of the valve retains the same pressure medium pressure even when the position of the valve is changed without any pressure drop occurring during the change. This is achieved by means of a change procedure which is accurately regulated in terms of position. Fig. 1. <IMAGE>
