Abstract: Polysilicon rods from the Siemens process are crushed into fragments and further processed to fragments having very low metal contamination in an economical manner by purposefully fabricating parts contacting the polysilicon from materials which cause high metal contamination, and removing the metal contamination by a cleaning bath or baths tailored to the particular metal contamination. By this process, economical materials previously scrupulously avoided, such as low alloy steel, can be used for crushers, conveyors, and other polysilicon-contacting parts of the crushing and classifying system.

Abstract: A method of forming circumferential grooves in pipe elements using opposed rollers to cold work the pipe elements determines the diameter of the groove while the pipe element is rotated between the rollers. A device for executing the method uses the instantaneous determinations of the groove diameter in a feed-back loop to control the operation of the device and halt groove formation when the groove diameter is within a specified tolerance.

Abstract: The present invention describes a rolling tool device for compression rolling of, in particular, blade elements of a rotor area of a jet engine provided with a tool carrier. The tool carrier is connectable to a carrier spindle. Furthermore, two pliers-type bodies are rotatably connected to the tool carrier. The pliers-type bodies are each provided with a rolling area, with a distance between the rolling areas being variable in dependence of the rotary movement of the pliers-type bodies. In accordance with the present invention, an axis of the carrier spindle in the state connected to the tool carrier passes between the rolling areas through a contact point present at a distance between the rolling areas equal to zero.

Abstract: A crimping apparatus includes a ram having crimp tooling for crimping a terminal to a wire during a crimp stroke and a force sensor detecting a crimp force during the crimp stroke. The crimping apparatus also includes a controller that monitors the crimp quality of a crimp based on a frequency profile of the crimp. Optionally, the controller may create the frequency profile based on a force profile using a frequency transform algorithm. The frequency transform algorithm may be a Fast Fourier Transform algorithm.

Abstract: An apparatus used to repair damage from metal body panels of a transportation container. The apparatus includes a platform having wheels that can optionally be locked. The apparatus further includes a pivoting arm that can be selectively raised, lowered, extended or retracted to repair virtually any area of a transportation container. At the end of the pivoting arm is a cross-arm member comprised of a piston repair arm that can be fitted with a plurality of attachments depending on the contours of the surface being repaired. The area to be repaired can include perimeter walls, ceilings, doorframes, and/or corner posts. The pivoting arm and piston repair arm are driven using a pneumo-hydraulic system that is lighter than any other system currently used on transportation repair devices. The substantial reduction in weight allows the apparatus to readily enter transportation containers and be easily handled by a single operator.
Abstract: A pressure relief valve for a hydraulic press tool, the pressure relief valve having a valve body, a fluid return channel, a needle and a seat, and the needle is movable between a closed position, in which the needle is in contact with the seat to block the channel, and an open position, wherein the needle is at a distance from the seat to allow fluid to flow in the channel, and the fluid flow then causes movement of the seat away from the needle and completes the opening of the fluid return channel.
Abstract: A retaining wall clamping assembly facilitates bracing of a temporary retaining wall. The assembly includes a bar having a first section coupled to a second section. The first section is selectively extendable and retractable relative to the second section. Each of a pair of jaws extends from an associated one of the first section and the second section. The jaws are aligned defining a clamp for engaging a retaining wall. A bracing aperture extends through the bar for coupling a brace to the bar by a connector inserted through the bracing aperture to support the retaining wall in an upright position.
Abstract: In a rolling mill, an open-loop and/or closed-loop control device and a method for adjusting a discharge thickness of rolling stock which passes through a multi-stand mill train, wherein a first section of the rolling stock is rolled to a first discharge thickness, a second section of the rolling stock is rolled to a second discharge thickness which is different from the first discharge thickness. Because a transition from the first discharge thickness to the second discharge thickness takes place at a feed rate of the rolling stock into the mill train which is adjusted as a function of a discharge rate of the rolling stock of a unit which is arranged upstream of the mill train in the direction of mass flow, a method can be made available which runs essentially without reactions for units which are arranged upstream of the mill train in the direction of mass flow.
Abstract: A roller forming device and method for forming a material provided with geometric elements, in particular holes, is disclosed. The device has at least one forming roller and at least one counter roller, wherein a roll gap is configured between the forming roller and the counter roller for carrying through the material. The forming roller has a molding structure on its cylindrical surface, which molds the material when the material runs through the roll gap. The forming roller has carrier elements for an engagement with the geometric elements of the material running through the roll gap.
Abstract: A method of manufacturing a power transmission chain pin, which connects links arranged in a chain width direction of a power transmission chain, includes a rough sectional shape formation step of drawing a wire rod so that a section thereof is formed in a substantially oval shape and a rough end portion shape formation step of cutting a continuous bar-like member which has been subjected to the drawing work into a predetermined length so that an end surface thereof has a predetermined angle with respect to an axial direction. A final sectional shape and a final end portion shape of the power transmission chain pin are formed by a cold forging work to the bar-like member cut into the predetermined length, which is a final shape formation step.
Abstract: A reinforcing bar binding machine is provided with a feed device for feeding a wire from a wire reel rotatably mounted on a binding machine body, a braking device for braking a rotation of the wire reel, and a control means that starts a braking to the rotation of the wire reel by the braking device after the wire is fed to a predetermined amount by the feed device.
Abstract: A device and a method of using the device for construction of baffles that may be used in suppressors or solvent traps for firearms out of metal cups sold as engine block freeze plugs. The device has a bottom die, a top die and an alignment cylinder. The metal cup is transformed into a baffle by placing the metal cup on the bottom die, placing the bottom die inside the alignment cylinder, placing the top die inside the alignment cylinder, and applying compressive forces to the bottom die and top die. A hole may be drilled in the center of the baffle by placing a drill bit into a top die center hole completely penetrating through the top die and coaxial thereto, and drilling through the baffle, the drill bit passing into a bottom die center hole penetrating at least partially into the bottom die and coaxial thereto.

Abstract: Provided is a technique which can, in order to guarantee the molding accuracy of hot press molding, accurately measure the temperature of a workpiece being subjected to the hot press molding. A hot press mold is a mold used for hot press molding for hardening and molding a workpiece, which has been heated, by pressing the workpiece. The hot press mold is provided with a stroke type temperature measuring device which is extended and retracted by a pressing force applied thereto through the workpiece. The temperature measuring device is provided in such a manner that the temperature measuring device protrudes outward from the molding surface of the mold, and when subjected to the pressing force applied through the workpiece while being in contact with the workpiece, the temperature measuring device shortens in length and retracts into the mold.
