Mads Lindegaard Lildholdt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9933101
    Abstract: A valve and a method for making the valve, the valve including a valve housing with a central part and with two connection ends, wherein internally of the central part there is arranged a valve body in a valve seat and connected to a valve spindle that is arranged in a spindle guide stub on the valve housing. The method includes a tubular workpiece being provided with a cutout, a plate-shaped workpiece being provided that is plastically deformed to form a collar on it whereby a spindle guide stub is formed with a collar along its lower edge and a cutout in its upper surface. The spindle guide stub is laser welded on the tubular workpiece providing an internal welding seam running along the edge of the inner opening in the collar of the spindle guide stub, along the cutout and at the outer side of the tubular workpiece.

  • Patent number: 9920843
    Abstract: A valve and a method for producing a valve for regulating a fluid, having a valve housing with a central part and with two connection ends, the connection ends extending away from the central part, wherein internally of the central part there is arranged a valve body including at least a shutoff part and a through-flow part. The valve seat is arranged in the valve housing and resiliently bears against the valve body, a resilient structural part has a spring action that acts in a direction substantially parallel with the flow direction of the valve and has at least one annular flange part adapted for bearing on the valve body. The resilient valve seat includes a fixing member for mechanical fixing of the valve seat in the valve housing. The fixing member has a flange part fixed in the valve housing by plastic deformation.

  • Patent number: 9777860
    Abstract: A valve and method for producing a valve for regulating a fluid, the valve including a valve housing with a central part and two connection ends, the connection ends extending away from the central part. Internally of the central part, there is arranged a valve body with a through-going aperture that is arranged in a valve seat and connected to a valve spindle, the valve spindle being arranged in a spindle guide stub on the valve housing. The valve housing is made from a plastically deformed tubular item and includes a collared spindle guide stub with at least one projection, the projection or projections extending in continuation of the spindle guide stub. This projection can be used as a lock ensuring that the valve spindle is retained in its intended position, and at the same time, such projections can form stops at the extreme positions of the valve body.

  • Publication number: 20160222481
    Abstract: A method and a system for stress-relieving annealing one or more first parts of a workpiece, wherein a second part of the workpiece contains heat-sensitive parts. A cooling jacket is placed around the part of the workpiece surrounding heat-sensitive parts such that the part{s) to be annealed are located outside the cooling jacket. The first part(s) are then heated individually by induction up to the annealing temperature of the material in a first annealing zone in the system while simultaneously cooling the second part of the workpiece located in the cooling jacket. After annealing, the workpiece is cooled in a cooling zone, as annealing and cooling of the workpiece occurs under a protecting atmosphere. The annealed workpiece is, e.g., connection ends on a valve housing where the connection ends are shaped by plastic deformation after mounting valve seats, valve body etc. in the central part of the valve housing.
