METHOD FOR EXTRACTING A CORE FROM A PERCUSSION SIDE WALL CORE BULLET FOR A DIGITAL TOMOGRAPHIC DESCRIPTION AND DIRECT NUMERICAL SIMULATIONS
20190339171 · 2019-11-07 ·

Embodiments relate generally to methods for extracting a core from a percussion side wall core bullet for a digital tomographic description and direct numerical simulations. A method for extracting a core from a percussion side wall core bullet for a digital tomographic description and direct numerical simulations includes pushing a free end of a wire of a wire saw through the core. The core is positioned within the percussion side wall core bullet. In addition, the method includes attaching the free end to a locking mechanism of the wire saw. Further, the method includes cutting the core from the percussion side wall core bullet. The method also includes removing the core from the percussion side wall core bullet.

Shaped saw wire with controlled curvature at bends

A saw wire to cut hard and brittle materials is disclosed that comprises a steel wire that is provided with bends with segments in between. The average degree of bending of the bends is between 0.5% and 5%. Such a saw wire has a higher breaking load compared to saw wires having a conventional, higher average degree of bending. A method to measure the curvature is described as well as a process to make the inventive saw wire. The invention is applicable to any shaped saw wire for example a single crimped saw wire, a saw wire with at least two crimps in different planes, a saw wire with crimps rotating in a plane.

Quick chain tensioning system
10434682 · 2019-10-08 ·

A quick tensioning system applicable to handheld chainsaws is provided wherein, during chain re-tensioning, the chain guiding bar remains firmly anchored to the bar holder and guiding means are provided to retract the motorized driving sprocket versus said guiding bar. The system includes a guide interposed between a stationary bar holding body and a motor body. This allows a linear or a rotation relative movement between the sliding driving sprocket and the stationary guiding bar. A drive is provided by means of a screw that an operator can easily operate via a knob conveniently mounted nearby the chainsaw handle.

Ingot cutting apparatus, and load detecting device used in ingot cutting apparatus

In an ingot cutting apparatus that cuts an ingot using a plurality of stretched wires, load sensors are provided on the new wire side and the old wire side of the ingot, and loads applied to the new wire side and the old wire side of the ingot are measured using the load sensors on the new wire side and the old wire side. When measuring the loads, for example, the center of moment about the X-axis that is the running direction of the wire is calculated. When the deviation from the center of gravity of the ingot is greater than or equal to a reference value, notification for replacement of the wire, control of the conveying speed of the wire, control of the pressing speed of the ingot, and so forth are performed through a control unit.
