Title: Garden rake
IPC: A01D7/06
Filed: 1979-07-25
Abstract: This invention relates to rakes. A rake 10 has a bifurcated head 11, between the arms 13 of which are rotatably mounted tines 17. The rotation of the tines can be limited by check bars 14 and 15 mounted one on either side of the tines 17. The check bar 15 has a resilient pad 23 mounted thereon between it and the tines 17. In use the tines 17 engage loose material on the surface being raked and when they engage an irregularity on the surface they are deflected to allow the rake to pass over the irregularity without digging in or bumping. Rotation of a line 17 causes compression of the pad 23 which in turn urges the tine 17 to return towards its original position once the rake has passed over the irregularity. <IMAGE>

Title: Secondary radar
IPC: G01S13/87
Filed: 1980-03-26
Abstract: In an airfield surveillance radar system, use is made of individual low power radars located along the lengths of the pathways (runways or taxiways) to be monitored. Each such radar is a low power device which radiates directionally so as to define a block on the pathway. The radar emits P1-P3 pulse pairs from one aerial such as used to interrogate aircraft equipped with ICAO standard SSR transponders, and each pulse pair generates a response which is received via that radar's receiver. In a first variant a suppression pulse P2 is sent from another aerial at the same station but floodlighting space not covered by its own P1-P3 pulse pair. The radars are on both sides of the runway and staggered. In a second variant all radars are on one side of the runway while opposed P2 transponders, triggered by respective P1 pulses are on the other side. In both cases the radars are cable-controlled from the central equipment to interrogate as requested. To deal with vehicles (including aircraft) not fitted with secondary radar the vehicles can have passive or semi-passive responders of the type used in anti-shoplifting systems. <IMAGE>
