IPC: H01Q19/195
Filed: 1967-12-19
Abstract: 1,167,598. Aerials. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 19 Dec., 1967 [30 Dec., 1966], No. 57621/67. Heading H4A. A radio wave reflector element consists of a metal conductor made up of three sections AB, BC, CD, Fig. 1, each of which is perpendicular to the other two. AB equals CD, each being less than #/2, where # is the working wavelength, BC equals #/2 x (¢+n). where n is zero or a whole number, and AB + BC + CD equals #/2 x N, where N is a whole number. Thus, AB or CD equals (2(N - n) - 1) #/8. The element reflects waves directed along its axis BC if they are circularly polarized in one sense, but transmits them if they are circularly polarized in the opposite sense. A plurality of elements may be mounted in a block M, Fig. 6, of dielectric material, such as foamed plastics, to make up a reflector structure. Such a structure may be curved, and in one embodiment (Fig. 7, not shown) a Cassegrain type aerial is described in which a primary radiator launches clockwise circularly polarized waves towards a sub-reflector which changes their sense of polarization to anti-clockwise. The waves are then reflected from a main reflector without change of sense of polarization, and pass through the sub-reflector as a collimated beam.

Title: Apparatus for sorting and handling mail
IPC: B07C3/06
Filed: 1971-12-15
Abstract: 1374093 Sorting postal mail MASSON SCOTT THRISSELL ENG Ltd 13 Dec 1972 [15 Dec 1971] 58262/71 Heading B8A Compartments 12 of a letter sorter are discharged into compartments of a shelf unit 70 (Figs. 2 and 4), which is mounted to traverse vertically, collecting stacks of letters from the vertically extending series of horizontally extending rows of the sorting compartments 12. The unit 70 when full, has its letters discharged into compartments of an output conveyer 21. Each compartment 12 has a base 34 for the letters which is counterbalanced by a spring 40. When the base 34 reaches its lowest position it operates a switch SW1 connected to logic circuitry (not described in detail in the Specification). The base may also be lowered by the operation of a motor driving a drum 54. This winds in a cable which passes over pulleys 56, 58, 59, and 60, and is anchored to a pusher plate 45. The latter is connected by a cable 53 to a spring drum unit having a lower return force than the spring 40. Deflection of the pusher plate 45 is blocked by the action of a roller 63 carried by the base 34, until the latter reaches its lowest position. When the pusher plate 45 then moves to deflect the stack into the corresponding compartment of the unit 70, vertical upward return movement of the base 34 is prevented by the action of an interlock roller 64. The plate 45 operates a switch SW2 at the end of its outward travel. Any letters above a predetermined maximum of the stack are retained by a plate 31 and are supported by a horizontal plate 51 which travels with the pusher 45. The plate 51 also serves to support any letters which arrive in the compartment 12 during the stack discharge operation. Sorting can thus be continued while the compartments 12 are being discharged. Photo-electric sensors 84 are responsive to the presence of letters in each compartment 82 of the shelf unit 70. When the latter is in its topmost position (Fig. 2), its compartments are discharged to compartments (104) (Fig. 1, not shown) of a conveyer 21 by pushers 90 slidably mounted on rods 94 (Fig. 7), and connected to endless drive belts 91. Each compartment (104) has a sensor not shown which prevents operation of the pushers 90 until every compartment 104 in line with the compartments of the shelf 70, is empty. The conveyer 21 leads to a bundling machine.

Abstract: 1282727 Proximity fuse THOMSON-CSF 23 Dec 1969 [27 Dec 1968] 62699/69 Heading H4D A radar carried on a moving object has a random or pseudo-random code generator feeding a modulator which modulates a C.W. signal by phase reversal according to the code, to provide transmission signals wherein the code is also fed through a delay to a correlator which also receives the video signals from a CFAR, the output of the correlator feeding a Doppler filter, a detector and a matched integrator which feeds a triggering circuit and wherein the receiving and transmitting aerials are separate and each have radiation patterns defined by two cones coaxial with the moving object. In a proximity fuse for a guided missile, a shift register 32 and feedback element 33 produce a pseudo-random binary code which is fed to one input of a modulator 2. The signal input from klystron 1, through isolator 19 is of a frequency higher than "normal" radar transmissions. The output of the modulator 2 is a C.W. signal whose phase corresponds to the code (Fig. 3, not shown). This signal is transmitted by aerial array 41, 42. Reflected signals are received by a second array 51, 52 and pass through a magic-T junction 60 which feeds a symmetrical mixer 61, 62. The second input to the magic-T being a portion of the unmodulated transmitted signal. The outputs from the mixers 61, 62 supply amplifiers 91, 92, amplifier 92 including thresnold circuits which are arranged to provide a constant false alarm rate. The output from the receiver will thus be a binary code, amplitude modulated by a Doppler frequency dependent on the velocity of the target. The received signals are compared in a correlator 10 with the modulating code delayed by an amount corresponding to a range within the missile detonation limits (R 1 , R 2  Fig. 1, not shown). Thus when the target is at this range, the correlation function is unity and the video signals pass to a bank of Doppler filters 122j, each covering a selected velocity range and each having a matched integrator 132j. These feed a threshold circuit 141 which actuates a trigger 142 to detonate the missile when a threshold S is exceeded. The aerials 41, 42 and 51, 52 may be arrays of linear elements or may be of a circular geometry and are arranged to have radiation patterns defined by two cones coaxial with the missile (Fig. 1, not shown). The pattern produces a narrow beam of 5 to 10 degrees. Thus the video signals must satisfy rigid conditions of angular position (due to aerial patterns), range (due to correlation) and velocity (due to Doppler filters) in order to detonate the missile. This ensures that the missile is unlikely to be detonated by interference or E.C.M. Also the use of a high radar frequency enables a low power to be used i.e. discrete transmission.
