Abstract: The invention provides a propeller shaft supporting structure where an annular supporting member obtained by connecting an inner ring and an outer ring to each other via an elastic member axially supports a propeller shaft through a center bearing at an inner side of the inner ring. In the propeller shaft supporting structure, a metal stopper piece formed in a simple cylindrical shape with no flange is press-fitted on the propeller shaft to abut on an inner race of the center bearing so as to position and fix the center bearing to an axially predetermined position. A thin annular metal plate is fixed to an inner peripheral portion of an annular rubber flange, and the annular metal plate is fitted on an outer periphery of an end portion of the stopper piece, thereby covering the opening of the inner ring with the flange.

Abstract: An apparatus and method for inserting a new service pipe into an existing high pressure service pipe that contains a leak, without the necessity of excavation or separately shutting off the supply of the high pressure gas upstream of the effected pipe section. A nosecone coupled with a unique stopper assembly allows a temporary sealing of the high pressure pipe between the main and the leak point, and insertion flow of a sealer through the nosecone, such that the sealer fills the annular space between the new pipe and the old pipe, providing a gas tight permanent seal. The end of the stopper assembly has temporary stop plug that must be drilled open to reestablish the communication of high pressure gas into the new pipe without the chance of flow entering the old pipe.

Abstract: According to the invention, the rear end of a preceding metal piece and a front end of a succeeding metal piece are heated, pressed and joined prior to the finishing hot rolling. An alternating magnetic field running through the metal pieces in the thickness direction thereof is generated in an end region on opposed faces of the respective metal pieces to perform heating. Another alternating magnetic field whose direction is reverse with respect to that of the former alternating magnetic field is partially generated in the end region on the opposed faces of the metal pieces and in either a region where the metal pieces exist or a region outside width ends of the metal pieces. This assures a uniform heating of the end region on the opposed faces of the metal pieces over their full width to reliably join the both metal pieces to each other.

Abstract: A device in door arrangements includes a plurality of door panels hingedly interconnected to pivot about respective pivot axes. The pivot axes are positioned Between the side walls of contacting door panels. The hinge includes a convex member and a concave member, the concave member forming part of the other door panel. These two members extend along the edges of the corresponding door panels, coinciding with the pivot axis, with each member collectively forming a bearing face. Each door panel has a main profile extending uninterrupted over the entire cross section, and the edge of the door panel exhibits a curved section extending in the thickness direction. Further, each door panel has rigidifying portions arranged in the edge area.

Abstract: A method and apparatus for joining metal pieces wherein the rear end of a preceding metal piece and a front end of a metal piece are heated and then pressed together prior to hot finished rolling. The temperature the ends of the metal pieces are heated to is a temperature range between the solidus and liquidus line temperatures of the metal(s) to be joined.

Abstract: The present invention relates to a non return valve which is provided by welding two lines in two flat upon each other lying film surfaces, which are then folded towards each other and after that they are joined together around the outer edges except the opening channel so that over pressure is formed when the container is filled completely or partly and then the non return valve starts to operate with safe sealing. The opening channel is formed between two against each other lying sections of film material, which sections extend from the outside of the container into it and are joined together right up to the opening channel.

Abstract: An expandable repair fitting for sealing and reinforcing polyethylene pipe includes a single or multiple middle section(s) that receives two end sections. The three sections are split into halves in order for the fitting to encapsulate the entire pipe to be repaired. Electrical heating elements in the form of wires are embedded within each section. The specific location of the wires causes the jointed halves to melt together when an electrical source is supplied to the wires, as well as causing a portion of each end piece to melt about the outer pipe diameter, thereby forming a sealed repair fitting. A portal is provided on the middle section to allow pressure testing of the integrity of the fitting. In a second embodiment, the repair fitting does not encapsulate the entire pipe circumference.

Abstract: The invention relates to a method for providing releasable joining together of spacers in pairs which are preferably formed by support blocks for pallets or support walls on pallets or other load carriers by joining the spacers by means of flexible straps or by means of other releasable joining means, like pins or clamps. Spacers which are unattached or which already are integral building units in a respective pallet, are fed forward by means of a hauling track compressed in pairs to a joining station after which they are joined together and clamped together tightly. The invention is also related to machines for performing the method.
