Abstract: The present invention provides an environmentally-friendly, fully recyclable composite mining screen which has sufficient rigidity to replace existing metal and metal covered plastic mining screens. The inventive composite screen insert contains stiff reinforcing fibers (glass, carbon, etc.) and exhibits the rigidity of metal and metal-covered plastic mining screen inserts so as to minimize deflection in use. The inventive mining screen is also completely recyclable because at the end of its useful life, the broken and used screen can be ground into polymer particles and the particles incorporated into new screens or other parts.

Abstract: A device for the batch reactive mixing and degassing of thermosetting polymers, such as polyurethane or similar, comprising at least one hermetically sealable container (1) in which the batch of thermosetting polymers is to be placed, a rotary plate (2) on which a satellite rotary plate is rotatably mounted, the container (1) being placed on said satellite rotary plate in order to cause said container (1) to rotate and to revolve, first means for driving the rotary plate (2) and second means for driving the satellite rotary plate, and means (3) for placing the container (1) under vacuum; said device is noteworthy in that it comprises means for controlling the first means for driving the rotary plate (2) providing a speed of revolution of the container (1) and a second means for driving the satellite rotary plate providing a speed of rotation of said container (1), said control means being capable of continuously varying the speed of revolution and the speed of rotation of the container (1) independently of on

Abstract: A method for manual casting of polymers, is used for production of a molded part. The production of the molded part comprises providing a mold with a cavity, preparing a liquid polymer according to a recipe, manually casting the liquid polymer into the mold and solidifying the liquid polymer in the mold resulting in the molded part. A system comprises the mold and at least one sensor Wherein the system uses parameter data to calculate the recipe. The system comprises an electronic device and a display, wherein the electronic device controls the display. The display shows during the production of the molded part at least a part of at least one production step of the recipe.

Abstract: The on-demand multimedia service is provided on the basis of multimedia data sources (3) each comprising at least one program stream. The program stream of a source is converted into a transport stream transmitted to a user terminal along a first channel by way of a telecommunication network. Packets describing elements overlayable on a video component of the transport stream are furthermore extracted from the program stream. In response to a request originating from the user terminal, the service platform converts at least one of the packets describing overlayable elements into a data page returned to the user terminal along a second channel different from the first channel by way of the telecommunication network. On receipt of the data page at the user terminal, the overlayable elements are recovered and displayed in overlay with the video component of the transport stream.

Abstract: A method of connecting people (A, B, C, D) in a telecommunications network includes a step (E10) of creating two or more groups (G1, G2) of people as a function of their profiles. It sets up (E20) successive interviews (EAB, EAC, EAD) between all possible combinations of the people belonging to the two groups. The setting up (E20) of each interview includes the following steps: selecting (E30) two people (A, B) belonging to the two groups, setting up (E40) one or more audio and video data streams (f1, f2) between those people at a predetermined time (t1), and breaking off (E50) the one or more data streams after a predetermined duration (D1). Use in a videophone dating service.
