Title: Improvements in radar systems
IPC: G01S13/42
Filed: 1963-04-10
Abstract: 1,017,966. Radar. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April l0 1963 [April 10, 1962], No. 14429/63. Heading H4D. A stacked beam radar system comprises a plurality of channels having overlapping beams A to G, Fig. 1 (not shown), stacked in elevation, and having error producing side lobes, Fig. 2 (not shown). It is required to block at least some of the channels when a signal is simultaneously received on predetermined combinations of said channels. Two examples of error producing combinations are given, and the circuit of Fig. 3 is designed to detect and react to these combinations. The combinations are: (a) The simultaneous presence of an echo in channels A and E or A and F, which combination indicates a powerful ground echo, requiring that all the channels be blocked, and (b) The simultaneous presence of an echo in channels A and C, with no echo in channel D, the echo being from a target at a range less than 50 kms., which combination indicates a fixed target of low elevation angle, requiring that channels A, B and C be blocked. To detect and deal with combination (a), an echo on channel E or F is fed via OR gate 1, to an AND gate 2, which produces an output when an echo appears on channel A and is fed to its second input. The output from AND gate 2 is shaped in peak and bottom clipper 3 and stops the output of NOT circuit 4. This removes an opening signal from AND gates a to g, such that all the channels A to G are blocked. To detect and deal with combination (b) echoes on channels A and C are fed to AND gate 5. The absence of an echo on channel D causes NOT circuit 7 to feed a signal to AND gate 5. Means 8 feeds a signal to AND gate 5 of a duration equivalent to 50 kms. Thus when combination (b) is present AND gate 5 produces an output, which stops the output of NOT circuit 10. This removes an opening signal from AND gates a, b and c, such that channels A, B and C are blocked. -

Abstract: 945,277. Tufting machines. CABIN CRAFTS Inc. April 16, 1962 [April 26, 1961], No. 14630/62. Heading D1G In a tufting machine each needle is associated with an upper and lower oscillating looper, and is arranged to move in the direction of work feed, whereby the needle loop is taken selectively by either the upper or the lower looper for the formation of loops of different heights. The machine is a modification of that described in Specification 889, 973, and each needle is arranged to co-operate with a pair of loopers printing either in a direction opposite to that of work feed for the formation of cut loops, or in the direction of work feeds for the formation of uncut loops. As shown, a needle N is mounted in a holder 61 pivoted at 62 to the vertically reciprocating needle bar 12. A spring 64 biaser biases the needle to the vertical position. A bell crank lever pivoted at a fixed point 72 has one arm 73 connected to the piston rod 75 of a pneumatic cylinder 76. The piston in the latter is spring-biased upwardly to position the other arm 71 vertically and out of the path of movement of a lateral arm 63 on holder 61. The needle then moves wholly vertically and cooperates with the upper looper 49a of a pair of loopers 49a, 49b carried by an oscillating bar 48, to form low loops. When air is admitted to cylinder 76 under control of a rotary pattern drum, arm 71 is tilted to the dotted line position and cooperates with arm 63 to tilt the needle, after the latter has entered the work C, to the dotted line position, in which the needle co-operates with the lower looper 49b to form high loops. In oscillating cutter blade 53 has a central split 53s providing a portion 53a co-operating with looper 49a and a portion 53b co-operating with looper 49b. In a modification the loopers point in the direction of work feed and the cutter blade is omitted. Fitting of the needle in this arrangement produces low loops. Specifications 916, 417 and 916, 418 also are referred to.
