Abstract: A system for shaping a workpiece, which may be in the form of a structural framing component, includes a tool with first and second indenting blades for indenting the workpiece as driven by a blade control apparatus. The workpiece is supported at the tool by one or more workpiece support modules that are each selectively and removably securable to the tool. A base plate is provided at the tool for removably securing the workpiece support modules to the tool without having to detach the tool from a platform of substructure. The workpiece support modules may therefore be quickly replaced to coordinate with workpieces of various size and shape.

Abstract: A process is provided for the continuous production of thin-walled, radially closed hollow profiles composed of nonferrous metals and having a small cross section comprises supply of a flat strip of the metal to a forming apparatus at a first supply speed, the thickness of the strip corresponding to the wall thickness of the hollow profile. The forming apparatus continuous forms the flat strip into a shape corresponding to the hollow profile. After forming, two opposite edges of the flat strip rest flush against one another in a contact region and are continuously welded by means of a laser which emits light having a wavelength of less than 600 nm. The laser heats an area in a welding region having a diameter of less than 20% of the cross-sectional dimension of the hollow profile. The welded hollow profile is taken off from the welding region and taken up in an uptake device.

Abstract: Improvements and modifications to coil steel straighteners provide an integrated structural head that allows for quicker setup of the equipment, integrated lower backup rolls to the structural head, self-aligning rollers, setup timing blocks for equipment calibration, and adjustment screw jacks that allow for narrower center distances and include pointers and scales internally. The backup rollers for each work roller are supported on separate backup roller plates enabling the backup rollers for each work roller to removably installed and independently adjusted. The backup rollers may be supported between opposing blocks and adjusted by moving the blocks toward and away from the backup roller plate using leveling jacks. The work rollers associated with the upper bank may be supported between opposing slide blocks that move up and down in slots formed in opposing side plates, with visual indicators to establish a zero position associated with each work roller in the upper bank.

Abstract: A process for converting spent grain into flour by drying and milling is disclosed. The process includes the steps of introducing a quantity of wet spent grain into a container for removing moisture by the action of gravity. After the gravity drying, the wet spent grain is transferred to a press to mechanically remove additional moisture. The wet spent grain is placed in a fluid bed processor where the grain additional moisture is removed through heating and fluidization. Some embodiments may include a dust collection system in connection with the fluid bed processor, wherein the dust collection system incorporates a separator for separating the grains. Once dried, the dry spent grain is introduced into a mill to be ground into the proper flour consistency. The resulting flour product can then be used for a variety of foodstuff applications.
