Patent EP-0336307-A2 (EP)
Inventor: JARVENPAA VILJO JUHANA
IPC: F16K15/14
Filed: 1989-03-30
Abstract: The invention relates to a non-return valve comprising parts (4 and 5) that form the body construction of the non-return valve. The non-­return valve is furnished with a closing element closing a pipe (4a) with a center part (8) of at least the pipe diameter, which center part (8) is connected to the outer periphery (13) of the closing element by intermediate spools, and/or with a closing part having an opening and an outer periphery (13). The closing element is made of an elastic and/or stiff material, and the intermediate spools between the outer periphery (13) and the center part (8) are located in a slanting position forming an angle with respect to the outer periphery (13) so that the closing element functions elastically and causes a turning movement to the closing center part (8), which produces the space required by the flow. The closing part and its opening can be placed on the closing element, in which case the closing element is preferably made of a stiff material. The invention also relates to a double valve, which is formed by combining closing elements and/or closing parts of the non-return valve according to the invention.

Abstract: In order to reduce the generation of noise when working with the cutter heads (1), the grooves (3) into which the cutters (2) are inserted are provided at an axial angle. However, the axial angle requires the longitudinal direction of the cutting edges of the cutters (2) to be produced according to a hyperboloid. But this can only be produced by expensive individual grinding of the cutter (2). For this reason, the cutter (2) is designed to be elastically flexible in its plane. The cutter (2) can thereby be bent elastically in its plane to produce the hyperbolic cutting edge. The knowledge of a person skilled in the art is not required for the bending operation. <IMAGE>

Abstract: A self-preparing electrode including a conductive element, for example a frusto-conical disk (12), for contact with the skin and a nonconductive abrading brush (14) removably interfitted through an aperture (24) in the conductive element. The brush extends through the cavity (18) of the conductive element to an abrading end (28) of the brush disposed beyond the cavity. The brush also extends axially through and beyond the aperture (24) to a fused end (30) of the brush which holds the strands of the brush together. An apparatus (32) which fabricates the brush and assembles it to an electrode disk uses a pair of pressure rollers (62, 64) to feed multiple strands (26) from supply spools (56) mounted in a supply rack (46), through input and output tubular orifices (80, 82), to and through the aperture (24) of the disk (12). A shuttle (90) positions a fusing anvil (88) in contact with the leading ends of the strands extending through the disk aperture for fusing them into a connecting bead. A cutting blade (98) is then employed to sever the strands a short distance from the disk to finish forming the brush and define an abrading end (28) thereon.

Abstract: The invention relates to an exhaust gas manifold of diesel engines with 9 or 18 cylinders, with nine linearly arranged and progressively numbered cylinders (1 to 9) per row, with a compound exhaust gas manifold (17) which extends along the cylinders and, in the case of an ignition sequence of the cylinders (1, 7, 4, 2, 8, 6, 3, 9, 5, 1) has an outlet to a turbocharger (10) at the end near to the first cylinder and a sealing cover (11) at the end near to the last cylinder while, in the case of a reverse ignition sequence of the cylinders (1, 5, 9, 3, 6, 8, 2, 4, 7, 1) it has an outlet to a turbocharger (10) at the end near to the last cylinder and a sealing cover (11) at the end near to the first cylinder. Specifically in the case of nine cylinders per row, the gas expulsion of one cylinder coincides with the scavenging procedure of the cylinder preceding it by two ignitions. The most dangerous pressure peaks, caused by reflection against the sealing cover (11), are smoothed by a restriction (12) in the exhaust gas manifold (17) whose cross-section of passage has an area of 40 to 60 % of the adjacent cross-section of the exhaust gas manifold (17), the mean pressure between the sealing cover (11) and the restriction (12) rising by about 0.1 bar. Overall, design advantages and low investment costs for the turbocharger (10) are obtained. <IMAGE>
