Abstract: 794,407. Aircraft arresting gear. BORGS FABRIKS AKTIEBOLAG. Oct. 25, 1956, No. 32577/56. Class 4. Arresting gear for aircraft on a runway or other landing surface comprises laterally spaced pillars 9, 12 each mounted on a base frame 16 for pivotal movement transverse of the runway and each provided with a pulley 8, 11 respectively for a support cable 3, 4. Each cable is secured by a readily releasable connection 6 to an arresting cable 2 which carries a slack lower cable 5, the cables 2 and 5 being connected by vertical cables 1. The outer end of cable 3 is anchored at 10 to the runway and the outer end of cable 4 is secured to a weight 13 which tensions cables 3 and 4 and the intermediate portion of cable 2. During operation, when an aircraft runs into the net, the resulting tension imposed on cables 2, 3 and 4 separates connections 6 and a braking device 7, to which one end of cable 2 is secured, exerts a steady braking force on the aircraft. The cable 2 may be rewound by a power or manually operated device 25. To enable the net to be lowered on to the runway when necessary, manually operated catches are freed to enable the pillar 9 and 12 to swing towards one another into substantially horizontal positions, though they may swing outwardly or both in one lateral direction or the other. The pillars are counterweighted.

A soil sampler comprises a sample tube 10 carrying a cutting ring 11, a valve head 12 and pipe means 14 supplying fluid, a slidable piston (23) (Fig. 3, not shown) co-operating with the valve head to discharge fluid (air) through apertures in the cutting ring as the sampler descends and through apertures in the valve head as it ascends. Air discharged through apertures 26, 27 helps the sampler to descend to the level at which a sample is taken. The air is cut off, and a pneumatic hammer applied to an anvil member 15 pushes the sampler further, while a cable 18 withdraws the piston (23) up the sample tube 10 on top of the column of soil entering the tube. As the tube becomes filled the piston engages a portion (40) of a valve member (36), lifting it so that fluid supplied will now discharge through apertures 37, 38 to facilitate withdrawal of the loaded sampler. In other embodiments (Figs. 5, 6, not shown) the cable 18 is replaced by spring clips arranged to hold the piston at the top of the sample tube 10 when the tube is full. Instead of a separate cutting ring a stainless steel tube may form its own cutting ring.
