A meat processing system comprising a blade, a blade movement assembly, a controller and a conveyor. The blade is configured to cut a carcass into pieces and lies substantially in a blade plane. The conveyor is configured to move the carcass along a first axis. The controller is configured to control the blade movement assembly to rotate the blade or a portion of the blade to vary an angle between the blade plane and the first axis. The blade movement assembly may also be configured to translate the blade to move the blade transverse to the first axis. A method of operating a meat processing system is also disclosed. The method includes conveying a carcass or section of carcass along a first axis, controlling a blade movement assembly to rotate a blade or a portion of a blade to vary the angle between a blade plane and the first axis, and cutting the carcass or section of carcass into pieces.

An inline edge-sealing apparatus and method for sealing the kerf surfaces of cut cellular PVC board includes a rotary saw with either a tandem sealing disc or with an integral elevated sealing surface that is dimensioned to provide precise interference with kerf surfaces for friction and heat to melt and seal the surfaces in an aesthetically desirable manner. A kerf splitter, such as a kerf splitting pin, rod or riving knife, may be provided following a saw blade with integral kerf-engaging surface to avoid disruption of the sealed surface when cut boards exit the saw blade teeth.

A horizontal sawing machine includes a support unit, a driving unit, and a sawing unit. The support unit has a slide rail base with two oppositely disposed stationary slide rails. The driving unit has a driving motor, a reducing gear box, and two oppositely disposed movable slide rails. The reducing gear box is connected to the driving motor and has an output shaft. The movable slide rails are provided on the outer periphery of the reducing gear box and are respectively engaged with the stationary slide rails to enable forward and backward movement of the driving unit with respect to the support unit. The sawing unit has a saw blade and a saw blade mount connected between the bottom end of the output shaft and the saw blade so that the saw blade is rotatable by and movable forward and backward along with the driving unit to facilitate operation.

An electric working machine may include an output shaft, a rotary blade attached to the output shaft, an output pulley fixed to the output shaft, an input shaft, an input pulley fixed to the input shaft, a transmission belt wrapped around the input pulley and the output pulley, an electric motor including a motor shaft and configured to rotate the motor shaft, a speed reducer configured to reduce a speed of rotation of the motor shaft and transmit the rotation to the input shaft, and a housing that houses the electric motor and the speed reducer, and rotatably supports the input shaft and the output shaft. A rotation axis of the motor shaft may be inclined with respect to a direction which is along a rotation axis of the output shaft.

Hockey sticks or other tubular shafts have historically been cut using a hack saw with the shaft resting on the lip of a garbage can resulting in slow and inaccurate cuts. A new device for cutting a shaft comprises a holder for receiving the shaft, and an arm rotatably mounted at an end of the holder. The holder includes an internal passage, sized to receive the shaft, which extends outwardly through an opening at the end of the internal passage. A set of jaws are mounted on the rotating arm, each jaw includes a saw blade extending across the opening perpendicular to the shaft. The jaws are spring biased together at a first end for engaging the shaft, whereby relative rotation of the arm and the holder results in the saw blades sawing the end of the shaft off with high precision. Each jaw may include a lever arm extending from a second end thereof configured to receive an application of a user force to overcome the spring bias force to enable the set of jaws to be separated for mounting the shaft therebetween.

A component according to the disclosure may include a body having an aperture therein for receiving one of a turbomachine shaft or a lathe chuck, wherein in response to the body being coupled to the lathe chuck, the aperture is oriented substantially axially relative to an axis of rotation of the body with the lathe chuck; and a flange coupled to and in direct axial contact with the body, the flange including a surface that extends axially relative to the axis of rotation of the body, wherein the surface of the flange comprises a matingly engageable face configured to contact an axially aligned surface during operation of the component and having a sanding indentation thereon, wherein a surface roughness of the surface of the flange is less than a surface roughness of a remainder of the component.

A shaft cutting tool incorporating a scissor assembly having a first arm, a second arm, and a hinge interconnecting the arms' proximal ends; a shaft mount attached to the first arm's distal end; and a cutting wheel assembly operatively mounted within a hollow bore formed at the second arm's distal end; wherein the cutting wheel assembly includes a drive axle and rotary bearing; and wherein the drive axle extends oppositely from the cutting wheel for engagement with a portable electric drill.

A bolt cutting apparatus including a cutter assembly and a carriage assembly attached to the cutter assembly. The carriage assembly includes a carriage housing, a tool post coupled to the carriage housing, a motor attached to the tool post, and a drive assembly configured to linearly move the tool post. The carriage assembly is configured to be secured to a structure, e.g. a flange. A cutter is attached to the motor and is disposed in the carriage housing. The motor is configured to rotate the cutter to cut a bolt on the structure, e.g. flange.

A ring cutter for transecting a ring trapped on an appendage. The ring cutter includes a body, a motor housed in the body, a blade drivingly connected to the motor, a guard coupled to the body, a guard actuator drivingly connected to the guard and controlling a movement of the guard, a current sensor positioned to sense electrical current associated with the motor, and a processor communicatively coupled to the current sensor and the guard actuator. The blade has a rotation axis and a peripheral cutting edge. The guard is insertable between the ring and the appendage to position the ring between the guard and the blade. The processor is configured to: i) receive, from the current sensor, an electrical current reading associated with the motor, and ii) transmit, to the guard actuator, one or more commands to control the movement of the guard based on the electrical current reading.

A control device according to some embodiments of the disclosure includes one or more motors directed by the control device to form whip(s) from a length of a cable by causing the cutting of the cable in accordance with specifications based at least in part on whip information. An interface communicates the whip information between the control device and a user device.
