A cutting system having a cutting portion arrangeable around an exterior area of an object to cut the object is disclosed. The cutting portion may be configured to deform from a first shape having a size substantially the same as a size of the exterior of the object to a second shape having a size smaller than the size of the exterior of the object to cut the object when the cutting portion is displaced. By virtue of having a cutting portion configured to deform from a first shape to a second shape to cut an object, the cutting system can take less time to cut an object and can prevent a user from cutting portions of his or her body.

A glazing panel removal device comprising a winder unit (1) having first and second winder spools (10, 11) for winding a cutting filament (100) and a drive, for driving the winder spools (10). The drive means includes a single or common drive input for driving both the first and second winder spools (10, 11). The drive maybe a rotary input drive, and driving the rotary input in a first rotary direction may cause winding of the filament (100) onto the first winder spool (10) and driving the rotary input in the opposite direction causes winding of the filament (100) onto the second winder spool (11).

A diamond wire saw and method provides a frame that includes a clamp that attaches to a target (e.g. piling, beam, tubular), an elongated toothed rack extending away from the mount and target, and a moving portion that carries the diamond wire and motor drives that advance the moving portion toward the target and along the toothed rack while driving the wire around roller guides.

A wire take-up and pay-off device, including: a wire take-up and pay-off driver; a rotating shaft, which has a rear end connected with the wire take-up and pay-off driver; a front stop sleeve, fixedly sleeved on a front end of the rotating shaft and rotating synchronously with the rotating shaft; a rear stop sleeve, fixedly sleeved on the rear end of the rotating shaft and rotating synchronously with the rotating shaft; and a wire roller, fixedly sleeved outside of the front stop sleeve and the rear stop sleeve and rotating synchronously with the front stop sleeve and the rear stop sleeve. Further included is a slicing machine having the wire take-up and pay-off device. The wire take-up and pay-off device and the slicing machine have small volumes, thereby facilitating assembly, hoisting and transportation.

A method and apparatus for forming a starter notch along the length of a work-piece for subsequent fatigue testing. The starter notch is formed with a cutting wire such that it will promote fatigue-cracking in the work-piece in one defined direction and avoids cracking in directions other than the length direction of the starter notch. Improved fatigue-testing analysis may therefore be realized.

A photovoltaic module includes a first protective element, a second protective element, photovoltaic cells that are located between the first protective element and the second protective element, an envelope in which the photovoltaic cells are encapsulated. The envelope links the first protective element to the second protective element and includes a first portion that is located between the photovoltaic cells and the first protective element, and a second portion that is located between the photovoltaic cells and the second protective element. The disassembly method includes separating the photovoltaic cells with respect to the first protective element and cutting the first portion of the envelope by an abrasive wire.
