  • Patent number: 6274076
    Abstract: A shaped cord (2) is postformed in the shape of a frame extruded onto a glass (1) and is slightly curved in the direction of the length of shaped cord (2). A forming mold (4) is used in a postforming operation, with lateral edges (11, 12) that are slightly above the surface of shaped cord (2). This avoids the creation of imprints in the form of lines or edges on the shaped cord, and a smooth transition is achieved between the postformed length of the shaped cord that attaches thereto.

  • Patent number: 6039907
    Abstract: To postform the region of transition between the initial part and the end part of a section piece forming a closed frame and applied to window glass (1) by extrusion, use is made of a mould (14) which pivots about an axis parallel to the longitudinal axis of the extruded section piece and which is situated in the region of the surface of the window glass (1). The axis of pivoting of the mould (14) coincides with the cutting ridge (15) of a protrusion (16) which limits the calibrated cavity of the mould (14) on the internal face of the extruded section piece. As the mould (14) pivots, the excess polymer material is pushed back in the direction of the periphery of the window glass and beyond this periphery.

  • Patent number: 5984656
    Abstract: The forming surface of a forming mold (5) for postforming of a shaped cord (2) in the shape of a frame extruded onto a glass (1) is slightly curved in the direction of the length of shaped cord (2). In the final position of forming mold (4) during the postforming operation, lateral edges (11, 12) are thus slightly above the surface of shaped cord (2). This avoids the creation of imprints in the form of lines or edges on the shaped cord, and a smooth transition is achieved between the postformed length of the shaped cord that attaches there.

  • Patent number: 5885695
    Abstract: This invention is related to a method for shaping profile an extrudable plastic material attached to a surface. In the process, a die being part of a cylinder and having a shape corresponding to the desired cross-section of the profile is introduced into the plastic material and is then extracted therefrom by rolling the cylinder. The invention is also related to a device for carrying out the process.

  • Patent number: 5253816
    Abstract: The invention relates to a machine for compacting and/or crushing bulk material, in which two rollers which can be pressed together at high pressure each consist of a main roller body and a roller shell which is releasably connected to the main roller body and is composed of individual segments. Each of the individual segments has one single lug projecting in the circumferential direction on the front long side in the direction of rotation of the roller and one single complementary recess on the rear long side in the direction of rotation of the roller. The generatrices of the outer surfaces of the segments point in the circumferential direction and run radially with respect to the roller axis. This results in a simple construction of the segments and a high degree of security against tilting.

  • Patent number: 4915311
    Abstract: The invention relates to a roller mill with two rollers, a grinding gap formed thereby and a material inlet shaft the end walls of which bear on their lower ends carrier plates with replaceable sintered metal wear parts. Each wear part is formed by a plurality of small sintered metal plates of small area which are set close against one another like a mosaic and are individually screwed onto the carrier plate so that in case of wear only those small sintered metal plates which are actually worn can be replaced simply, quickly and economically.

  • Patent number: 4554199
    Abstract: A thermoplastic synthetic high polymer sheet including induced tensile stress lengthwise of the sheet which varies in intensity from a maximum along one edge to a minimum along the other edge. The induced tensile stress is frozen in the sheet by maintaining its temperature below a transformation temperature. Upon elevation of the temperature of the sheet above the transformation temperature, as the process of fabrication of a laminated windshield is to commence, the sheet, without further operative forming operations, will deform to conform substantially to the outline of the outer curved lamina of the windshield. The sheet may include a zone along one edge to provide filtering of glare.

  • Patent number: 4322116
    Abstract: A hydrodynamic bearing for supporting a rotary member has a bearing gap between the rotary member and the bearing and which is occupied by fluid. Hydrodynamic pressure in the gap is monitored by a sensor which is coupled to a starting aid that is responsive to variations in the hydrodynamic pressure to switch on and off a starting aid. Upon being switched on the starting aid is operable to deliver additional fluid to the bearing gap.
