Abstract: A technique provides for wireless control of a machine tool, e.g. a portable machine tool used on-site. According to an embodiment, a motor is connected with a tool post assembly via a gearbox. The motor is coupled with a machine controller, and the tool post assembly is mounted proximate an object to be machined. For example, the object may be machined via a cutting tool mounted to a cutter post of the tool post assembly. The machine controller operates to control movement of the cutter post along a desired axis during the cutting operation. The machine controller and thus the cutting operation, however, are controlled wirelessly according to control instructions provided via a control device, e.g. a handheld control device, which is placed in wireless communication with the machine controller.

Abstract: A technique which facilitates cleaning of an interior of a pipe via access through a lateral hole in the pipe. The technique utilizes a control bar head coupled with a sweeper system which may be inserted into the pipe through the lateral hole. The sweeper system may comprise a plurality of shiftable sweeper heads which generally align for insertion through the lateral hole and then transition along the interior of the pipe to effectively sweep particles along the interior of the pipe. The sweeper system effectively clears an area of the interior of the pipe to facilitate a more effective seal with a subsequently inserted pipe isolation device.

Abstract: 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.

Abstract: This disclosure discloses a balance vehicle, comprising: a wheel, a support frame, a frame, a shock suspension component, foot pegs, a control rod and a handle grip; the support frame is fixed to an axle of the wheel; the frame is connected with the support frame in a slide way through a sliding block fixed to the support frame; the shock suspension component is disposed between the frame and the support frame, and configured to buffer the relative movement between the frame and the support frame; the foot pegs are fixed on the frame; the control rod can move forward and backward in the driving direction, and is configured that: when a driver pushes the control rod forward in the driving direction, the balance vehicle is accelerated; when the drive pulls the control rod backward in the driving direction, the balance vehicle is decelerated or draws back.
