Abstract: A length of microstrip line (3) turns through successive right-angle comers to form a rectangular pattern comprising successive quartets (a,b.c,d) of such comers. Each right-angle comer radiates with a polarisation which is predominantly diagonal, and the strip lengths (8,9) between the comers of each quartet are made such, in relation to the operating wavelength in the strip, that the radiation from each quartet sums to produce a desired polarisation direction, e.g. vertical, horizontal, or circular of either hand. Some forms of the stripline antenna can be used in a resonant as well as a travelling-wave mode, the latter giving a main lobe whose direction sweeps with frequency.

Abstract: Le projectile cylindrique (13) est engagé dans le tube propulseur (1) de façon que son fond se trouve en contact avec le fond (5) qui ferme la culasse (4) prolongeant le tube (1). L'enceinte (8) communique avec le tube (1) grâce au conduit coudé (7) et à l'ouverture latérale qui est ménagée dans la culasse (4) et raccordée au conduit (7). Quand le projectile est en place, les garnitures (14, 15) obturent toute communication entre le tube (1) et l'enceinte (8). Cette dernière peut être remplie d'air comprimé par exemple au moyen d'un raccord vissé dans un des trous taraudés (12). Il suffit dès lors de déplacer le projectile (13) vers l'avant par enfoncement de la tige (16). Sous l'effet de la poussée de l'air le projectile se déplace et les dimensions du passage libre augmentent rapidement, ce qui assure un effet propulsif maximum.

Abstract: The apparatus comprises two runners which are situated in front of a crossbar and form the forward supports of a T-shaped beam. A central shank is pivotingly connected to a rocking-lever which rests on two other runners. Twin wheels of the rear axle of a load-bearing vehicle advance, while the apparatus continues to rest on its four runners, from a position in which the wheels are in line with the rear runner of the rocking-lever to a position in which they are in line with the front runner of the rocking-lever. Although both of these runners are successively situated in the zone where the road surface is deformed, their movements are complementary, so that the pivoting axis remains at the same level. The T-shaped beam thus forms a reliable reference for a horizontal plane relative to which measuring arms pivot, so that the movements of feelers aligned with the front runner of the rocking-lever can be recorded.
