Abstract: An improved method for creating cooling ducts in cast resin coils uses uniform cross section thermoplastic tooling segments. These segments are wound into windings between predetermined layers or radial sections, oriented parallel to the coil axis. They extend through the height of the coil. After the coil is cast, impregnated, or saturated with resin, and the resin is cured, the segments are withdrawn. The removal of a segment results in a continuous cooling duct. The thermoplastic segments are either solid machined from sheet or extruded with thin outer walls. Extrusion allows for uniform cross section relatively long somewhat flexible segments, which will cause the radius of curvature of the segment to conform to the shape of the coil due to the tension from the conductor and reinforcing material during the winding process. This will have the result of reducing the number of different segment designs required to support production of a variety of different diameter coils.

Abstract: A multiply-acting powder metal press is disclosed for making green form double helical gear compacts. The press has inner and outer lower punches, and an upper, outer punch. The upper and lower outer punches have left hand and right hand external helical profiles as chosen to produce a desired helical gear. The punches co-operate with left hand and right hand helical dies carried by the press about the punches. The helical faces require that the dies rotate relative to the punches during operation. A cam and roller mechanism may drive this rotation. The compact forming process commences with an open position in which powder is introduced to a vacant lower die cavity. The upper portions of the press advance downward to close the cavity. All parts of the press except the lower inner, or transfer, punch then move downward at the same speed to transfer powder to the extremities of the cavity. When transfer is complete both lower punches may be stopped, while the upper punches continue to advance.

Cyclically compressing the elastomeric member in the predetermined repeat pattern prior to installation of the energy absorption apparatus on the railroad car effects permanent deformation of the elastomeric member while maintaining the preload force developed for the energy absorption apparatus to remain at a substantially constant maximized level simulating a predetermined wear condition for the energy absorption apparatus.
