Abstract: 1295799 Vibrators LOSENHAUSEN MASCHINENBAU AG 19 Oct 1971 [12 Dec 1970] 48581/71 Heading F2X  An oscillation generator, in which a centrifugal weight held against rotation about its axis is orbited by rolling on a rotary member, has the centrifugal weight 32 rbckably mounted on one side in an axially-adjustable rocker bearing 30 and engaging via a conical recess 34 over a driven roller member 18 tapering after the fashion of a bead. The roller member 18 is keyed to the shaft 12 of a vibration-proof electric motor 10 and a casing 14 is attached to the motor 10 by screws 16. A rubber sleeve 36 attached both to a plate 24 secured to the casing 14 by screws 38 and to the centrifugal weight 32 secures the weight against rotation while allowing it to orbit around the rocker bearing 30. The bearing 30 is mounted in an axially-adjustable screw-threaded spindle 26. In operation, the centrifugal weight 32 makes an orbiting, planetary movement around the driven roller member 18 at a frequency, in relation to the drive frequency, in the ratio of the contact diameter of the roller member to the  difference between the contact diameters of the recess and the roller member (i.e. d : D - d). Adjustment of the spindle 26 can make the centrifugal weight 32 move further and further over the roller member 18, so that the contact diameters d and D change in opposite directions and therefore the frequency can be altered steplessly within wide limits.

Abstract: 1297958 Pulse radar; aerials MARCONI CO Ltd 27 Feb 1970 [23 May 1969] 26492/69 Headings H4A and H4D A radar having means for determining the azimuth of several target echoes received simultaneously at its antenna has a thin transmitting beam produced by a linear antenna array arranged at an angle to the vertical covering a large azimuth angle wherein at least part of the beam forms an angle with the horizontal and the radar also has means for scanning in azimuth. An array of slotted waveguides produces, by arranging the slots in the array and phasing of the feeds thereto, a thin beam which is substantially the shape of part of the surface of a cone whose apex is at the antenna and which is substantially tangential to the horizontal at its lower end, Fig. 3. The projection of the beam on to the horizontal covers approximately 90 degrees. Rotation of the antenna causes the point of intersection of the beam and the vertical plane at any given azimuth direction to sweep downwards in elevation, Fig. 5. Thus, as the antenna rotates the receiver denotes in which 1 degree azimuth channel the target is situated and the timing of the echo denotes the elevation. The curved shape allows greater sensitivity for low elevation targets. Alternatively the beam may be flat at 45 degrees to the horizontal, in which case sensitivity is linear.
