Abstract:
A process for the manufacturing of interior panels (1) by utilizing injection molding and a mold (10) having a mold cavity (20). The panels (1) comprises a carrying structure (2) of thermoplastic material and a panel insert (3) covering a portion of a front surface of said panel (1). The process comprises the steps of arranging a precut sheet of the panel insert (3) in a predetermined portion of a mold (11). The mold (10) is then closed and the panel insert (3) is fixed to a front face (12) of the mold (10) by means of fixing pins (13). The mold cavity (20) is then parted into an insert cavity (23), arranged on the rear side of said panel insert (3), and a main structure cavity (21) by means of a sealing slider (14). A first portion of molten thermoplastic material is distributed at a low pressure in the insert cavity (23) whereupon said first portion of thermoplastic material is allowed to solidify somewhat. The sealing slider (14) is then retracted after which a second amount of molten thermoplastic material is injected into the main structure cavity (21) utilizing a high pressure, said second amount of molten thermoplastic material being allowed to merge with said first amount of thermoplastic material so that a unit is formed. The injected thermoplastic material is allowed to cool and solidify so that the mold (10) can be opened, the interior panel (1) be removed from the mold and the process may be repeated.
Abstract:
A permanent magnet rotor (106) for a do brushless motor generally comprised of a non-insulated shaft (202) and a permanent magnet (206) is formed in one embodiment by compacting a powdered permanent magnet material substantially about a non-insulated shaft (202) of relatively incompressible material utilizing dynamic magnetic compaction (DMC) techniques. In other embodiments, the rotor is comprised of a non-insulated shaft, a magnetic core (204) and a permanent magnet and is formed by first compacting a powdered core material substantially about the non-insulated shaft (202) of relatively incompressible material to form a magnetic core and then compacting a powdered permanent magnet material substantially about the core to form a permanent magnet, with the compaction of the powdered materials occurring by DMC. Other embodiments may be formed by simultaneously compacting a powdered core material (204) and a powdered permanent magnet (206) material about a non-insulated shaft (202) of relatively incompressible material utilizing DMC techniques.
Abstract:
A stator is provided for an electrical device (e.g., a motor) comprised of one or more stator segments (Fig. 1B, 102) formed by the compaction of one or more powdered metallic materials. Each stator section has at least one tooth (Fig. 2, 206) that forms a substantially toroidal path for magnetic flux (Fig. 5, 506) entering and leaving the stator segment (Fig. 2, 202). Each stator segment also has a continuous insulated electrical winding (Fig. 6, 602) that is associated with the stator segment such that a magnetic field is induced in the stator segment when a current is passed through the continuous insulated electrical winding. The current that is passed through the continuous insulated electrical winding of any one stator segment is not of the same electrical phase as the current that is passed through the winding of any adjacent stator segment.

Abstract:
A tool rig (10) for the compaction of particulate materials includes a base and a cylinder block (12) disposed on the base (14). At least two pistons (16, 18) are disposed within the cylinder block (12) and one piston is at least partially disposed within one other piston. A supply component is disposed in the inner diameter of at least one of the pistons and defines at least one channel. The channel connects an energy supply to at least one of the pistons (16, 18).
Abstract:
The present invention includes a high performance communications cable exhibiting reduced cross-talk between transmission media that includes one or more core support-separators having various shaped profiles which define a clearance to maintain a spacing between transmission media or transmission media pairs. The core may be formed of a conductive or insulative material to further reduce cross-talk. A method of producing this cable introduces a core support-separator as described above into the cable assembly. The specially shaped core support-separator can be either interior to the cable jacket or be employed singularly without the benefit of a jacket and extends along the longitudinal length of the communications cable. Alternatively, with no jacket for cable completion, a portion of the separator wherein a thin layer of material can act as a type of skin for future mechanical protection is provided. The specially shaped sections of the core support-separator has a central region that is either solid or partially solid. The cable may include a plurality of shaped sections that extend outward from the central region along the length of the central region. The specially shaped sections of the core support-separator may be helixed as the core extends along the length of the communications cable. Such a helix or "lay length" may be defined by the difference between laying the conductors longitudinally parallel and straight with respect to each other or each pair and the amount of twist that each conductor or pair of conductors exhibits wthin the finished cable. Each of the adjacent specially shaped sections defines a distinct clearance channel that extends along the longitudinal length of the core support-separator. Each of the defined clearance channels allow for disposal therein of conductors and/or optical fibers.

A method for the high-velocity compaction of a part from particulate material is disclosed. The method includes the steps of providing a cavity that is at least partially formed by at least one bottom punch, inserting a pre-form that includes at least two levels into the cavity and moving an energy controlled main ram toward the pre-form at a high velocity to increase the density of the pre-form and form the part. A multiple-level part from particulate material and a high-velocity compaction press are also disclosed.
