Some examples of a cable cutting system include a first cutting apparatus that includes a recess to receive a cable. The system includes a second cutting apparatus separate from and attached to the first cutting apparatus. The second cutting apparatus includes multiple cutting surfaces arranged to cut the cable received at the recess.

Embodiments of a system and a method for manufacturing a gypsum board can be used to produce a gypsum board having at least one perforated cover sheet via a cover sheet perforator system. The cover sheet perforator system can include a perforator roller is disposed downstream of a forming station along a machine direction, a roller support frame for rotatably supporting the perforator roller such that its rotational axis extends along the cross-machine direction, and a motor arranged with the perforator roller to rotate the perforator roller about the rotational axis. The drive motor can be adapted to rotate the perforator roller with a tangential speed substantially equal to the line speed to produce a series of perforation holes in an upwardly-facing cover sheet as the gypsum board moves past the perforator roller.

A housing has a first end and a second end, an inner surface of the housing defining a channel that is configured to slidably receive therein a food product. A food product motivating mechanism is configured to engage a food product, the food product motivating mechanism being slidably receivable in the first end of the housing, the food product motivating mechanism and the housing being configured to cooperatively slidably urge a food product from the first end of the housing toward the second end of the housing. A rotating cutting mechanism is removably attachable to an outer surface of the second end of the housing, the rotating cutting mechanism being configured to rotate about the second end of the housing, the rotating cutting mechanism being further configured to cuttingly engage a food product.

An arcuate or circular cutting and/or marking apparatus comprises a bridging element comprising legs engageable to a grid base, wherein the bridging element comprises a circular cutting and/or marking element extending from a bottom of the bridging element for cutting and/or marking material, and a rotary handle connected to the circular cutting and/or marking element extending from a top of the bridging element for rotating the cutting and/or marking element. Systems and methods of the same are further provided.

A food processing apparatus for the cutting of foodstuff comprising a first cutter having a cross/sectional shape defining a first maximal external diameter and a first minimal internal diameter about a first central axis. A second cutter having a cross-sectional shape defining a second maximal external diameter and a second minimal internal diameter about a second central axis is also provided. The second maximal external diameter of the second cutter is greater than or equal to the first minimal internal diameter of the first cutter. In use, the foodstuff is cut by the second cutter before being cut by the first cutter, or alternatively the first cutter may make the first cut with the second cutter making a second subsequent cut.

A heavy-water reactor facility dismantling apparatus according to an embodiment includes: a first cutting device for cutting the periphery of a first nozzle portion of a calandria, wherein the first nozzle portion is connected to the upper end of a first pipe positioned in the calandria of a heavy-water reactor facility; a second cutting device for cutting a first support part of the calandria, wherein the first support portion is connected to the lower end of the first pipe connected to the first nozzle portion; and a fixing and drawing device for fixing and drawing the first nozzle portion cut by the first cutting device.

A saw has a system for sensing the torque on a cutting blade to signal when the blade begins to cut material. The saw has a drive belt extending between a driven wheel and a drive wheel and a belt tensioner that engages a side of the belt and maintains tension in the belt. The belt tensioner is movable to maintain the tension in the belt. A control system calculates the movement of the belt tensioner. The saw has a system for determining the size of the sacrificial blade. A through beam photoelectric emitter and receiver pair are positioned on opposite sides of the blade such that a largest cutting blade is moved above the beam regardless of a horizontal position of the cutting blade and sensor senses a vertical position of the axis of the blade. The sensor senses the vertical position of the blade axis when the blade is moved above the beam.

An oscillatory power tool that is capable of using various types of cutting tools is disclosed. The power tool includes an output shaft for mounting one of the cutting tools and driving the cutting tool in an oscillating rotary motion. An end of the output shaft has a driving section for engaging with a securing section of the cutting tool. The power tool further includes a fastener connected to the output shaft at the end and connectable to the securing section of the cutting tool for fastening the cutting tool to the end of the output shaft. The driving section has a fitting surface for contacting a surface of the securing section. Through a close fit between the friction surface and the surface of the securing section, the power tool can be connected with different types of cutting tools, which greatly improves the universality and convenience of the power tool.
