Abstract: A device for converting electrical energy at a high operating frequency, supplied by an electrical network having a capacitor placed between a line and an earth of the device, the capacitance of the capacitor being such that the high-frequency noise is filtered and an inductor placed parallel to the capacitor and having a low resonant frequency corresponding substantially to the frequency of the electrical supply network. The device provide filtering in order to prevent the transmission of high frequency interference from the device to the electrical network while preventing, as far as possible, leakage currents through the filter. The device is useful in the electrical network for an X-ray apparatus.

Abstract: A muzzle brake for a large or medium caliber barrel. The muzzle brake has a body whose inner dimensions are substantially greater than those of the barrel and which is fitted with at least one stage of two openings prolonged by vanes upon which the propellant gases are applied to create a force in the opposite direction to that generated by these gases. The muzzle brake comprises a tubular component prolonging the free end of the barrel, that is engaged in the body and pierced with several vents directing the propellant gases towards the vanes. The diameter of the tubular component is roughly between the caliber of the barrel and the diameter at the bottom of the rifling grooves of the barrel.
