Title: Apparatus for drilling holes by electron beams
Inventor: HOWARD CURTIS GILMORE
IPC: B23K15/08
Filed: 1984-07-30
Abstract: During the drilling of holes having a very small diameter in a workpiece 24, the material 40 expelled from the workpiece tends to travel along the path of the electron beam and to form a deposit 50 inside the gun 22. Most of the debris will be deposited in the recess 54 of the edge 60 of the rotating internal protective device 44 located on the side of the path of the beam in the gun. The angle of deflection alpha of the electron beam is adjusted accurately, so that the material expelled from the workpiece enters the recess from which it is removed by a scraper. A stop 64 is placed in the recess on the edge of the protective device and helps in removing small quantities of deposits still adhering to the movable parts of the electron-beam gun system alongside the protective device. In this embodiment, an effective scraper such as a metal brush 66 is used for removing the debris adhering to the edge of the protective device.

Title: Method and device for perforating thin metal sheets which can be used for the separation of a liquid-solid mixture
IPC: B21D28/36
Filed: 1985-05-28
Abstract: The method consists in passing strips of thin metal sheets or foils between two knurled wheels, one grooved and the other toothed. The knurled wheels, pressed together, entrain the strip, from which a defined shaping is obtained as well as a perforation without removal of material. The object of the invention is a novel manufacturing method, with the aid of which a machine designed for this purpose makes it possible, by means of a mechanical action between two rollers (called knurled wheels) having special profiles to confer on the foil or strip of thin metal sheet the characteristics particular to its use. Execution of this method results in rapid perforation, one hundred thousand holes per minute (approximately).
