    • A device for measuring the pressure of tires, particularly for aircraft, comprising a passive sensor adapted linearly to convert a variation in pressure into an electrical information variation, in situ, means adapted to convey the electrical information from the sensor to the cockpit of said aircraft, a self-oscillator whose oscillation frequency is controlled by the value of said electrical information from the sensor and means adapted to convert the signal issuing from said self-oscillator into a D.C. voltage proportional to a frequency variation, said frequency variation being proportional to said variation in pressure, characterized in that the electrical information from the sensor, before transmission into the cockpit, is applied to the terminals of the primary winding of a high frequency transformer, said primary winding being mechanically fast with the wheel, the secondary winding of said transformer being concentric with respect to the primary winding and mechanically fast with the stationary part of the landing gear, the ratio n of transformation between the primary winding and the secondary winding modifying the electrical information from the sensor according to the square of said ratio n.

    • A tent peg to positively prevent collapse of a tent under strong winds. The tent peg has a straight elongated body and a short angularly directed branch near the upper end thereof, adapted to be set to the vertical to be inserted within and attached to a tubular tent post to prevent its horizontal and vertical displacement. The tent peg is further provided with means to resist its pulling off the ground. These means include teeth on the body and the fact that in one embodiment of the peg, the body has a V-shape cross-section tapering towards its ground-engaging pointed end, whereby trapping earth, which resists pulling. The peg is provided with means for attaching tent cords, tent metal eyelets to further maintain the tent in erected position. The peg is also provided with means to interconnect it with another peg driven at an angle forming a V-shape arrangement within the ground to further resist pulling the peg off the ground.
    • 一个帐篷挂在积极的防止帐篷在强风下崩溃。 帐篷钉具有直的细长主体和靠近其上端的短的有棱角的分支,适于被设置成竖直以插入并附接到管状帐篷柱以防止其水平和垂直移位。 帐篷钉还具有抵抗其从地面脱落的手段。 这些装置包括身体上的齿和在钉的一个实施例中,身体具有朝向其接地尖端渐缩的V形横截面,由此捕获抵抗拉动的地球。 钉子具有用于附接帐篷帘线,帐篷金属眼孔的装置,以进一步将帐篷保持在竖立位置。 钉子还设置有将其与在地面内以形成V形布置的角度驱动的另一个钉相互连接的装置,以进一步阻止将钉离开地面。
