Abstract: The invention relates to a cold-rolled and annealed steel sheet with a strength greater than 1200 MPa, the composition of which comprises, the contents being expressed by weight: 0.10%?C?0.25%, 1%?Mn?3%, Al?0.010%, Si?2.990%, S?0.015%, P?0.1%, N?0.008%, it being understood that 1%?Si+Al?3%, the composition optionally comprising: 0.05%?V?0.15%, B?0.005%, Mo?0.25%, Cr?1.65%, it being understood that Cr+3Mo?0.3%, Ti in an amount such that Ti/N?4 and Ti?0.040%, the balance of the composition consisting of iron and inevitable impurities resulting from the smelting, the microstructure of the steel comprising 15 to 90% bainite, the remainder consisting of martensite and residual austenite.

Abstract: A microwave bandstop filter comprises a waveguide segment of cross-section that presents longitudinal variation of sinusoidal type modulated by an amplitude function that is continuous, the period of said longitudinal variation of sinusoidal type being the Bragg period for the fundamental guided mode at a center frequency of the band to be stopped. A filter assembly comprises a microwave lowpass filter presenting a cutoff frequency and at least one interfering passband at frequencies higher than said cutoff frequency, and at least one bandstop filter as defined above, connected to the output of said lowpass filter, in which the amplitude and the period of said longitudinal variation, and also the length over which it extends are such that they stop said interfering passband of said lowpass filter. An output multiplexer for a multichannel microwave transmitter includes such a filter assembly.

Abstract: The device is equipped with the classical catheter (1) finishing in its front end in a tip (2) for attachment to the neck of the uterus, which is prolonged by a cannula (3) of smaller diameter. The device has said cannula (3) closed by means of an elongated lid (4′), with a rounded face, with a perimeter depression and concave curve (8) at the middle level, where orifices are established (5′) as an outlet for the semen, specifically two orifices in diametric opposition, whose positioning is such that they are level with the uterine horns of the pig to be inseminated, by the introduction of the catheter (1), which is defined by a mark (11) in the cannula (3) or in a connector (12), which optimises the conditions of insemination allowing a lower semen consumption. In addition, the rear end of the lid (4′) has a diameter after the cannula (3), to protect the edge of the free end from the latter, avoiding damage to the mucus of the female to be inseminated.
