Abstract: A breech plug for inline muzzle loading firearms configured to use a blank powder cartridge loaded from the breech end, rather than powder loaded from the muzzle, and configured to place the projectile in substantially the same location in the barrel as if powder had been loaded from the muzzle end.

Abstract: The present invention discloses a calibration device of vector network analyzers implemented by means of SIC, ESIW and microstrip technology. The calibration device of the present invention has the special characteristic of being a modular device comprising connection modules (5) which are connected, on the one hand, to the vector analyzers and, on the other hand, to calibration modules (which may be SIC, ESIW or microstrip modules). This modular configuration allows that the noises intrinsic to the connection with the analyzer (including transfers to microstrip, SIC, etc.) are the same in all calibration measurements, making it possible to detect and/or eliminate the noises associated to said connection.

Abstract: The invention relates to a wireless knife for cutting and spreading cold food consisting of a knife equipped with a heating system that heats the blade at the moment of use thereof, characterized in that it comprises a blade, preferably consisting of stainless steel, titanium or the like, with a heating resistance insulated by sheets of mica, and a handle provided with a rechargeable battery that can be extracted by means of a screwed top arranged on the handle that has a hole that can be adjusted to the support projection of a charging base connectable to the mains by means of a cable and a plug. The handle has an electronic control plate, a secondary coil, a push button, a regulator and a tricolor light-emitting diode. The support projection has a primary coil which induces the secondary coil. The positions of the regulator correspond to the colours of the LED.

Abstract: An exemplary system for securing objects to a substrate with a non-penetrating securing device. The non-penetrating securing device is a non-destructive device that allows objects of a variety of sizes (large and small) to be securely mounted to or on fragile substrates.
