Abstract:
A method for operating a device for automatically feeding bars or half-finished bars to a machine tool such as a computer numerical controlled (CNC) lathe, and automatically unloading workpieces machined from the bars includes loading a bar through the rear into a spindle of a lathe via a loading/unloading device including an integrated bar feeder device, a magazine configured to receive at least one bar to be machined, and a loading/unloading beam; machining the bar in a machining space in front of the lathe; and unloading the bar by actuating the loading/unloading beam after the bar has been completely machined in order to recover a bar end in the machining space and to transfer the bar end to a trash bin for residual material and rejects. The loading/unloading beam is capable of successively or simultaneously moving at least in a vertical Z axis direction and a horizontal Y axis direction.
Abstract:
An apparatus for feeding bars to a machine tool including an end adjacent a working zone in which a spindle is provided; a drum element, rotatable around an axis; a movable support provided on the drum element for supporting and guiding a bar parallel to the axis. The movable support slidably drivable on the drum element parallel to the axis between a disengagement retracted configuration and an engagement extended configuration. The movable support having telescopic tube configured for being received inside tubular housing and guide for coupling with the spindle. The telescopic tube defines, a cylindrical containing structure configured for enclosing and supporting in a distributed manner a respective bar along the entire supporting zone, so as to prevent the bar from flexing because of the centrifugal actions generated by rotation.

Abstract:
A mandrel for manufacturing a vascular device for treating a vessel includes an elongate strand and a plurality of bulbs coupled to the elongate strand. The elongate strand may extend through each of the plurality of bulbs. The mandrel may include first and second elongate strands each including a plurality of bulbs. The first and second elongate strands may be separable at an intermediate portion coupling the first and second elongate strands. A vascular device manufactured utilizing the mandrel may be configured to treat a vessel.

Abstract:
A system for removal of slag during laser cutting of a hypotube by a laser cutting system may include a cooling system and a cooling fluid inlet regulator. The cooling system may be configured to be coupled to a laser nozzle of a laser cutting system. The cooling system may include a supply of gas and a gas inflow valve configured to regulate the gas that flows into the laser nozzle from the supply of gas. The cooling fluid inlet regulator may be configured to inject cooling fluid into an inner lumen of a hypotube during laser cutting by the laser cutting system at a velocity configured to facilitate removal of slag generated during the laser cutting of the hypotube. The cooling fluid inlet regulator may be configured to cool the hypotube during the laser cutting.
Abstract:
A device for disrupting flow through a fistula may include a woven textile having a compressed state and an expanded state. The woven textile may include, in the expanded state, a neck, a first bulb coupled to a proximal side of the neck, and a second bulb coupled to a distal side of the neck. The neck has a first braid angle. The first bulb may have a second braid angle greater than the first braid angle. The second bulb may have a third braid angle greater than the first braid angle.
