The present invention concerns a Machine (10, 10′) for simultaneous cutting of a plurality of slabs (18) from a block (B) of stone material through a plurality of band saw blades (11), wherein each of said band saw blades (11) is closed in a loop between a respective driving pulley (12) or a shared driving drum and a respective driven pulley (13) or a shared driven drum, said driving pulleys (12) or said shared driving drum rotating around a first axis (A) of rotation, or respective first axes of rotation parallel to each other, and said driven pulleys (13) or said shared driven drum rotating around the same second axis (A′) of rotation, parallel to said first axis (A) of rotation, or respective second axes of rotation parallel to each other and parallel to said first axes of rotation, said axis (A) of rotation of the driving pulleys (12) or of said shared driving drum and said axis of rotation (A′) of the driven pulleys (13) or of said shared driven drum being in turn mounted on a frame (14) movable with respect to said block of stone material, along two directions (x,y) incident to each other, one direction (x) of cutting said block (B) of stone material, said direction (x) of cutting being disposed on a plane (τ) of cutting of said slabs (18), said plane (τ) of cutting being in its turn incident with respect to a direction (y) of relative advancement of said block (B) of stone material with respect to said frame (14), characterised in that the plane (π) to which said direction (x) of cutting and said direction (y) of relative advancement of said block (B) of stone material with respect to said frame (14) belong is horizontal and at least the portion of the path of each of said band saw blades (11) included between respective movable spacers (19) is inclined with respect to the vertical of an angle (β) comprised between 3 and 20° in the direction of cutting.

A band saw that is convertible between a vertical cutting position and a horizontal cutting position includes a work table extension that extends from a work table when the band saw is used in the horizontal cutting position. The work table extension is removable from the work table and is attachable to a blade guide when the band saw is used in the vertical cutting position.

A mobile ordnance disposal system to dispose of unexploded ordnance in situ by cutting open the ordnance casing and subjecting the explosive material to heat in order to burn the explosive material held within the casing in a controlled manner instead of generating an explosion to effect disposal. By using the system, the operator may remain at safe, remote distance controlling the system operation.

An automated saw wherein: the automated saw comprises one or more visual sensors, a meat positioning assembly. The automated saw is configured to analyze an uncut meat and calculate one or more cutting depths for one or more cut portions from the uncut meat. The uncut meat comprises a first end and a second end. The first end of the uncut meat can be analyzed by the automated saw by: capturing a first slice image of the first end, locating a first bone configuration and a configuration of one or more meat portions in relation to the first bone configuration, and measuring portions of the one or more meat portions to categorize which among one or more cuts of meat is presented at the first end of the uncut meat. The automated saw calculates a first cutting depth for a first meat portion.

An exemplary embodiment of the present invention provides an apparatus for dismantling for heavy water reactor facilities, including: a cutting device configured to divide a calandria of the heavy water reactor facilities into a main shell and a sub-shell; and a transfer device configured to draw the main shell cut by the cutting device to the outside, wherein the transfer device includes a fixing unit configured to fix the calandria; and a transfer unit configured to transfer the fixing unit.

A device for mounting and dismounting a band-saw blade has a movable support frame and a plurality of retaining elements distributed on said support frame and configured to temporarily adhere to the outer flat side of the band-saw blade at various locations along the contour of the band-saw blade, thereby exerting an outwardly directed force on the outer flat side of the band-saw blade.
