Abstract: A reforming assembly for simultaneously reforming and reprofiling a bottom portion of a metallic container is provided. The reforming assembly generally includes a roller block having a pair of reform rollers and two pairs of outside reprofile rollers. A biasing means is operably interconnected to the reform rollers, such that the reform rollers extend to contact the inner surface of the bottom portion of the container when contacted by the bottom portion of the container. The outside reprofile rollers engage with an outer surface of the bottom portion of the container. The container reforming assembly is rotated, while maintaining the container body in a static non-rotating position, to create an internal can profile on the inner surface by the pair of reform rollers, and an external can profile on the outer surface by the outside reprofile rollers.

Each bearing has a mount receiving a portion of the workpiece therein. When the workpiece is supported by the bearing mounts along a support axis, and is engaged by the press ram intermediate the workpiece supports for bending correction, the bearings and workpiece can move in at least one plane including the support axis. Preferably, the bearings also allow rotational movement about the support axis, while a rotation imparting member allows twist correction by rotational movement of one bearing and the workpiece portion therein with respect to the other bearing which is restricted from rotating.

Abstract: The invention relates to a method for specifically adjusting the surface structure of rolling stock (3) during cold rolling in skin pass mills. The aim of the invention is to partially transfer the surface structure of the working roll (2) onto the rolling stock (3). To this end, the change of roughness of the rolling stock (3) in the rolling process of a single- or multiple-stand, preferably two-stand skin pass mill is calculated in an optimization calculation in which the rolling parameters are varied according to the mill capacity using a tribological model that mathematically describes the friction conditions in the roll gap (1). The results obtained are then used to readjust at least a part of the rolling parameters used for calculation.

Abstract: A method for measuring and displaying the flatness of a rolled steel sheet is disclosed that includes the steps of measuring tension in the sheet at a plurality of locations on the surface of the sheet and determining a plurality of tension ranges into which the sensed tension level can fall. A color is associated with each of the tension ranges, and a representation of the sheet is produced that is made up of a plurality of regions, each region having a color corresponding to tension range into which the tension sensed at the corresponding location on the surface of the sheet falls. A device for carrying out this method is also disclosed.

Abstract: Lightweight metal containers are formed from high-strength metal alloys by impact extrusion of a cup-shaped container having a substantially larger diameter than the finished container, drawing and wall ironing the extruded container to reduce its diameter and wall thickness while increasing the height of the container to the appropriate diameter, wall thickness and height.

Abstract: The eccentricity of a hollow billet is measured at the outlet of an inclined-roll rolling mill by launching an ultrasonic pulse into the billet from a laser of a measuring device and measuring the transit time of an echo pulse also utilizing a laser and an optical analyzer. The measuring device is moved, during travel of the hollow billet along a path from the rolling mill linearly into the direction of travel or angularly around the hollow billet to eliminate the effect of the internal helical formation of the eccentricity on the measurements. The wall thickness measurements are evaluated by a computer and subjected to Fourier analysis.

Abstract: The dash bridge and hook rescue device is a two piece emergency rescue tool utilized in the extraction of accident victims from underneath a dashboard and steering column as the result of an automobile accident where severe injuries are incurred by the victim. The rescue device is used to expedite the lifting and removal of the steering column and dashboard using existing winches, power spreaders or extension ram devices, either manual, air or hydraulic powered, to engage the hook attached below the steering column and lift it from the dash bridge spanning from the hood of the car to the roof of the car, bridging the windshield through which the hook extends, and lifting the steering wheel in a vertical direction off the lap and chest of the victim. Unrestricted access to the victim from the passenger compartment of the vehicle and transfer to emergency transport vehicles for critical care is expedited over other existing emergency extraction device techniques.
