Abstract: A center drive cutter chain (10) for mounting on a cutter bar (12) comprises center drive cutter links (14) having forward and rearward pivot openings and pairs of oppositely disposed side links (20) pivotally inter­connected by pins (22) to the cutter links (14) and alternating non-cutter drive links (17). The side links (20) each have forward and rearward pivot openings and forward and rearward bar engaging undersides (26, 28). For the side links (20) following a center drive link (14), the width of each side link (20) between its forward pivot opening and forward bar engaging underside (26) is less than the width between its rearward pivot opening and rearward bar engaging underside (28). When the axes of the pins (22) extending through the pivot openings of the cutter links (14) and following side links (20) are substantially in a plane, the forward bar engaging undersides (26) of the side links (20) are spaced apart from the adjacent side rails (24) of the bar (12). This spacing enables the center cutter link (14) to pivot about its forward pivot opening to reduce the penetration of the cutter tooth (15) into the workpiece, thereby reducing the vibration of the chain (10) when the cutter link encounters resistance in a workpiece.

Abstract: A video signal processor for processing a composite video signal to be fed to color liquid crystal (LC) panels of a color liquid crystal display which are each assigned to a different color. The pedestal level of each color signal included in the video signal and to be fed to particular one of the LC panels is caused into coincidence with the level of an input signal which reduces the transmittance of the LC panel to the lowest transmittance. The pedestal level is caused to agree with the clipping level of either one of a dark and a white clipping circuit, whereby signal components lower than the pedestal level are removed. The processor insures the maximum contrast available with LC panels and eliminates light-and-dark inversion, thereby enhancing the reproduction of high quality pictures.

Abstract: The invention relates to a hydraulic striking mechanism including a cylinder, a percussion piston guided therein and a piston return device which is supported on the percussion piston and is displaceable independently thereof and can be connected on its side facing the percussion piston tip alternatingly to a pressure source or a pressure-free return conduit. The piston return device is configured as an annular piston which is freely displaceable along the percussion piston and the cylinder and forms therewith a piston chamber. The percussion piston has an abutment face at its end remote from the percussion piston tip which cooperates with the annular piston for moving percussion piston in the return stoke direction. The percussion piston, together with the cylinder, defines an oil chamber which axially follows the piston chamber in a spaced relationship. The percussion piston is provided with a cylindrical shoulder within the oil chamber which determines its end position during the return stroke. The piston chamber and the oil chamber are connected with a control unit by means of which, when the percussion piston shoulder approaches the rear face of the oil chamber, the oil chamber can be connected to the return conduit and by way of which, when the annular piston approaches an annular face on the cylinder, the piston chamber can be connected with the pressure source.

Abstract: Described are a method and a device for regenerating an ink sheet or ribbon (12) having on an insulating layer (9) an ink layer (10). The ink sheet or ribbon comprises non-­transferred portions (11a) where the ink layer (10) is still present and transferred portions (11b) where the ink layer (10) has been removed by a preceding image forming process. In order to fill up the transferred portions (11b) with ink again, charged electrically conductive ink (7) is made to adhere by an electrostatic force at an intermediate roller (3) having on an electrically conductive layer (1) a dielectric layer (2) or a photo-electrically conductive layer. The ink carrying circumferential surface of the in­termediate roller (3) is brought into contact with the ink sheet or ribbon (12) to be regenerated. By supplying a charge to the side of the insulating layer (9) of the ink sheet or ribbon (12) an electrostatic force, larger than the first mentioned one, is established between the trans­ferred portions (11b) of the ink sheet or ribbon (12) and the electrically conductive ink (7) on the intermediate roller (3). Thereby, the ink (7) is selectively transferred from the intermediate roller (3) to only the transferred portions (11b) of the ink sheet or ribbon (12).

Abstract: The engine comprises a combustion chamber with a volume which can be varied by the displacement of a piston in this cylinder according to a reciprocating movement, combustion occurring in the presence of a liquid having at least a raised percentage of water. The process is characterised in that the liquid is introduced into the combustion chamber by injection whilst the temperature and the pressure in the chamber are raised following ignition of the mixture in such a way as to produce a separation of the liquid into oxygen and hydrogen and a composition of the latter. The liquid is introduced by means of an injector comprising a mobile assembly (13) controlled by the pressure in the combustion chamber. The invention can be utilised to combat pollution of the environment due to the exhaust gases from motor vehicles. <IMAGE>
