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 device for taking a sample from a solid body by cutting out, having a frame and a cutting tool retained on the frame in such a way that the cutting tool can be moved relative to the frame, wherein the cutting tool, at least in parts, at least substantially has the shape of a hollow spherical cap or a hollow spherical segment. A method for taking a sample from a solid body by cutting out is implemented with the device.

A food processing apparatus for the cutting of foodstuff having a guide arrangement. A primary cutter is located at an open first end of the guide arrangement. A secondary cutter is located at or about a second end of the guide arrangement distal the first end. The guide arrangement guides foodstuff cut by the primary cutter towards and into contact with the secondary cutter for further cutting and/or processing by the secondary cutter.

A drilling apparatus has a work robot mounting a drilling blade and moving inside a main pipe and a photodetector for detecting the contour of an opening image formed on the inner surface of a pipe lining material by illumination light. The opening image is scanned, and a two-dimensional image corresponding to the opening image is generated based on the contour points P0 to P8 detected by the photodetector for display on a display unit. The amount of positional deviation between the center of the two-dimensional image on the display unit and the axial center C of the rotary shaft of the drilling blade is calculated, and the pipe lining material is drilled by moving the drilling blade by the amount of positional deviation in a direction in which the positional deviation is eliminated.

A mechanical part-stream sampler includes a housing positionable over a conveyor belt from which material is to be sampled. The housing encases one or more cutter arms and adjustable cutters. The cutter arms rotate 360 degrees such that the cutters extract a sample of material from the conveyor belt and deposit the sample in a discharge chute in the housing for later analysis. A programmable logic controller and human machine interface screen can be used to operate the sampler and to control the timing and speed of the cutter arms.
