Abstract: An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.

Abstract: An electromagnetic fire control system that includes a conductive surface and a power source such that the power source supplies power so that the conductive surface generates an electric field, the electric field is manipulated and interacts with a fire such that the fire is controlled.

Abstract: The invention relates to a clock movement including a frame (6) having a barrel (1) that contains a mainspring, a finishing gear train (2-4), an escapement mechanism (5, 7), and a spiral balance spring (8). The frame (6) comprises first clamp bodies (25, 24) for receiving respective pivotal movement members of the escapement wheel (5) and of the anchor (7), and second homologous clamp bodies (22, 26) alternating with the first clamp bodies (25, 24), the first and second clamp bodies (25, 22) of the escapement wheel being located on a circle centered on the axis of the mean wheel (3) of the finishing gear train and defining a plane that is orthogonal to said axis.

Abstract: A method and apparatus for manufacturing an optical fiber includes the steps and/or means of: drawing a fiber from a heated preform by applying a pulling force to the fiber; spinning the fiber while it is drawn, wherein the step of spinning the fiber includes the sub-steps of winding the fiber on a spin roller by a winding arc, such that a friction force is generated between the fiber and the spin roller resulting from the winding arc and from the pulling force; axially displacing the spin roller such that the fiber is caused to roll over the spin roller surface by the friction force.
