An arrangement for the electrical earthing of an electrically conducting cable with an outer insulating protective cover. A hydrothermal exchange unit accommodates water heat exchangers, water pipes, pumps and a controller, and is connected to the heat source unit via refrigerating pipes and electric wiring. The timing signal generator generates a timing signal that controls an operation of the image processing circuit using the frequency dispersion clock signal, in synchronism with the predetermined modulation cycle used for the frequency dispersion. In order to improve the axial position between the winding support and the end winding during operation of the stator, a coupling device is provided which allows relative movements between the end winding and the winding support in the circumferential direction and at right angles to the envelope surface, and prevents such relative movements in an envelope line direction. The biopsy sampling and marker release are integrated for one hand operation in a single device. The machine may further include a work material conditioning apparatus having a substance dispenser connected with a substance storage tank mounted on the machine, and configured to dispense the desired substance to the work material responsive to a signal from the sensor associated with a relative moisture content of work material within the machine.
